These are the minutes for 2022, for 2023 see Task Team Meeting - Rolling Agenda and Minutes 2023.

ICU Database Task Group Meeting – November 24, 2022

  • Present: Allan, Julie, Tina, Pam, Pagasa, Val, Barret, Joanna, Mailah, Mindy
  • Minutes prepared by: AG
  • Action items in BOLD

1. Transition to Database Server#Shared Health - Nothing new about either of the possible alternative options for hosting the database.

2. Two related issues: (a) APACHE Comorbidities in ICD10 codes - Moving to automated identification of the five APACHE II comorbid conditions, and (b) Non-standard ICD10 Diagnoses - Adding non-standard ICD10 Diagnoses to APACHE II codings for chronic conditions or admit diagnoses.

  • Allan has done both of these tasks, and what remains to be done is: (a) Tina to reformat them for integration into our existing data infrastructure (ACCESS and SAS) (Tina has done), (b) send the reformatted version to Allan so he can ensure completeness (Tina has done), and finally (c) Tina/Julie to incorporate them into workflow and backdate them to 1/1/2019.
  • Allan and Tina to meet about this later today.

3. Location metadata storage - Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. Validating new types of DSM results - Update on lab issues -- Allan and Tina have a followup meeting planned with Dr. Sokoro and Alun Carter.

5. Controlling Dx Type for ICD10 codes - Regarding the task (led by Barret) to improve data collector diagnosis assignment into the 3 "bins" of admission diagnosis, acquired diagnosis and comorbid diagnosis.

  • Lisa believes there is capacity to have one of the experienced collectors to work with Barret on this task. Lisa, Barret and Julie to meet about this soon.

6. New item: for Pre acute living situation field, how to code group homes. After discussion, we recognized that group homes, "Supportive Housing" and assisted living exist on a continuum of care levels in the community. Furthermore, no user has ever asked for this information. Thus, we agreed to combine them altogether. To this end Tina will create a new value for this field (to be called something like “Community Facility with support”, and distinguish it from PCHs.

7. New question: now to code transfusion-associated fluid overload. Answer is combine one of the Congestive Heart Failure codes with Iatrogenic problem NOS, related to a surgery or procedure, NOS, and of course to code the transfusion as a procedure.

8. Next Task meeting January 11, 2023 at 11 am

ICU Database Task Group Meeting – October 27, 2022

  • Present: Allan, Julie, Tina, Pam, Pagasa, Val, Brynn, Barret
  • Minutes prepared by: AG
  • Action items in BOLD

1. Transition to Database Server#Shared Health - Nothing new about Shared Health helping us move hosting by Digital Health forward. Last we heard (via Bojan), Perry thought this was a dead issue as the Shared Health lead for Quality had resigned. Allan sent an email to Bojan about this today, to get an update.

2. Two related issues: (a) APACHE Comorbidities in ICD10 codes - Moving to automated identification of the five APACHE II comorbid conditions, and (b) Non-standard ICD10 Diagnoses - Adding non-standard ICD10 Diagnoses to APACHE II codings for chronic conditions or admit diagnoses.

  • Allan has done both of these tasks, and what remains to be done is: (a) Tina to reformat them for integration into our existing data infrastructure (ACCESS and SAS), (b) send the reformatted version to Allan so he can ensure completeness, and finally (c) Tina/Julie to incorporate them into workflow and backdate them to 1/1/2019. Tina has worked through the list and sent additional comments to Allan and Julie.

3. Location metadata storage - Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. Validating new types of DSM results - Update on new lab listings, which appear to duplicate prior listings.

  • Allan sent to Tina the replies from DSM (Dr. Sokoro) about whether any of the new codes need to be added to our list for the purpose of tabulating the number of labs performed.
  • More generally, Dr. Sokoro clarified that: (a) the lab never eliminates test codes, but (b) creates new codes when new assays are introduced and when a new analyzer type begins usage. Thus over time the test codes we’d want to use to count the usage of certain tests will change. For example, in the next year DSM plans to purchase new analyzers which will result in new codes for many/most tests.
  • Tina pointed out that in order to keep abreast of these changes, and also to allow us to appropriately parse the DSM data stream we receive, she needs a contact as DSM to whom she can talk about these changes. Allan spoke with Dr. Sokoro about this issue, and there is a plan for Allan, Tina and Abdi to meet to discuss this.

5. Allan provided information, from Dr. Martha Sheperticki at St. B about the 2 new service listings in Cognos: SBGH Internal Med / Respiratory, SBGH Palliative Care / Respiratory.

  • These are non-teaching services run by Respirology Attendings. Though they do borrow Medicine Ward beds for these patients, when a patient is on these services they are no longer considered Medicine Ward patients. Thus we should not capture information for those services. Lisa updated STB Medicine Collection Guide. Julie will remove from our Medicine database records information from when patients are on those services.
  • Allan sent an email notification to Drs. Chisick and Renner to be aware of such fluctuations in St. B Medicine Ward bed numbers in interpreting utilization data.

6. Pam raised a query about the legacy item Urosepsis. Allan updated this Wiki page.

7. Lisa questioned how to code viral meningitis when the clinical team believes this is present but there are no supportive culture findings. Allan clarified that this is the usual situation for viral meningitis and one should code Meningitis, viral - incl West Nile along with Virus, NOS.

8. Controlling Dx Type for ICD10 codes - In discussion after this meeting, Allan and Barret determined a way of trying to make faster progress on going through all the diagnosis codes for the purpose of improving data collector assignment into the 3 "bins" of admission diagnosis, acquired diagnosis and comorbid diagnosis. Specifically to ask at the next Database Steering Meeting whether we can pay one or another of the experienced data collectors to help in this task. Allan has emailed Roseanne to put this on the agenda.

9. Next Task meeting Nov 24 at 11 am . Next JALT meeting on Nov 11 at 11 am.

ICU Database Task Group Meeting – September 28, 2022

  • Present: Allan, Julie, Tina, Mailah, Gail, Pam, Pagasa, Stephanie, Mindy, Michelle, Joanna, Brynn, Barret
  • Minutes prepared by: AG
  • Action items in BOLD

1. Transition to Database Server#Shared Health - Nothing new about Shared Health helping us move hosting by Digital Health forward.

2. APACHE Comorbidities in ICD10 codes - Update on moving to automated identification of the five APACHE II comorbid conditions. Status is these have been updated now Tina and Julie to review them; after finalization and implementation Julie will backdate to 1/1/2019.

3. Location metadata storage - Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. Validating new types of DSM results - Update on new lab listings, which appear to duplicate prior listings. Nothing new to report, Allan has a meeting planned for next week with Dr. Sokoro.

5. Update on use of Post COVID-19 condition vs. Past history of Covid-19 infection

  • Lisa will check to ensure it was clarified on the Wiki.

6. Non-standard ICD10 Diagnoses - Allan has gone through the Non-standard ICD10 Diagnoses and sent to Julie and Tina the list of those that should be included in APACHE II codings for chronic conditions (APACHE Comorbidities in ICD10 codes) or admit diagnoses (APACHE Acute Dxs in ICD10 codes).

7. Although we agreed last meeting to cease coding of routine swabbing for COVID-19, today after discussion we agreed to maintain the “button” that codes SARS-COV2 (the coronaviral cause of COVID-19) as an organism and the isolation procedure.

8. New issue: Cognos has begun having 2 new services: SBGH Internal Med / Respiratory, SBGH Palliative Care / Respiratory. These usually appear as transfers from IM wards. As it’s unclear what these services represent (continued IM ward care vs. actual transfer off of such ward care), Allan emailed Dr. Martha Shepertiki about this today.

9. New issue: How to code an exchange transfusion?

  • This is very rarely done in Manitoba -- the most common indication is Sickle Cell crisis
  • Surprisingly, in CCI exchange transfusion of RBC is included in the code for any other Transfusion of PRBC (1.LZ.19.HH-U1-J) , which is already one of our Picklist CCI codes.
  • Thus, we should just use this code for transfusion, INCLUDING the number of units transfused. The fact that the individual usually will have a code for Sickle cell crisis should clarify the situation.

10. New issue: Meaning of “organic” in Organic brain disorder, NOS.

  • Answer: It indicates a state of cerebral dysfunction associated with a disturbance in any of consciousness, cognition, mood, affect, and behavior in the absence of drugs, infection, or a metabolic cause. These usually are due to fixed, anatomic abnormalities, though these do not always show up on brain imaging.
  • Allan has added this to the Wiki.

11. Followup on the prior issue of location transfers where the recorded discharge is "after" the recorded admission (link_suspect_negative_transit_time query). In February 2022 we decided to not worry about such “negative” intervals if they were <30 minutes. Pagasa reported that with that alteration we have approximately 6 of these events per week. After discussion, we agreed that this number is sufficiently small to handle them by having Pagasa send queries to the collectors for correction.

12. New issue: Julie received a request for details of trachs inserted during time in ICUs from 2010-2020. An issue making this difficult is that the data addressing this has changed over time: (a) pre-2013 we used TISS-76 which had new insertion, (b) from 2013-2018 we used TISS-28 which has trach present but not new insertion, and (c) since 2019 we’ve used TISS-28 plus the CCI code for new insertion. Julie pointed out that from 2010-2020 there are >500 instances where the available trach-related data elements were inconsistent, with most of these being 2010-2018.

13. JALT issues -- including leftover ones from before, and new ones:

  • Visit_Admit_DtTm differences within same admission - Update/reminder about when Visit Admit DtTm in Cognos is DIFFERENT for records included within a single hospitalization. Julie to forward next few of these to Tina who will analyze them, and if it seems they're an ADT/Cognos error it may require reporting it to be fixed to Charity.
  • Reminder about ambiguity in the ICD10-based algorithms Allan created for the APACHE Acute Diagnoses. Allan checked and fixed them, and sent the updated file to Julie and Tina, who will check if these are now finalized.
  • Update/reminder about patients (ICU>Medicine) with very short LOS. Julie did an analysis and found that virtually all of these with LOS of 15 mins or less died. Increasingly as these short LOS grow longer (say to 1-2 hrs) the % who die falls. We hypothesize that for those who don't die but have LOS<2 hrs that most are getting sent from Medicine to ICU or being transferred to a different hospital. To check this out Julie will itemize, separately for Med and ICU, the dispositions of patients with LOS of 2 hrs or less who didn't die.

14. Next Task meeting October 27 at 11 am

ICU Database Task Group Meeting – Sepbember 7, 2022

  • Present: Allan, Julie, Tina, Lisa, Mailah, Gail, Pam, Pagasa, Stephanie, Mindy
  • Minutes prepared by: AG
  • Action items in BOLD

1. Nothing new about Shared Health helping us move hosting by Digital Health forward.

2. Update on moving to automated identification of the five APACHE II comorbid conditions. Status is these have been updated now Tina and Julie to review them; after finalization and implementation Julie will backdate to 1/1/2019.

3. Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. Update regarding the universal, unique patient identifier in Cognos, ClientGUID field. Tina reports: (a) we are currently obtaining it behind the scenes but (b) it is unlikely to replace our D ID field.

5. Regarding transfer ready issues -- Julie, Allan and Tina met and finalized this, with changes made in the Wiki.

6. Update on new lab listings, which appear to duplicate prior listings. Nothing new to report, Allan to discuss with Dr. Sokoro.

7. Update on use of Post COVID-19 condition vs. Past history of Covid-19 infection

  • Lisa will check to ensure it was clarified on the Wiki.

9. Update on decision to stop collecting Previous Service field -- Tina has implemented it Ttenbergen 09:21, 2022 September 8 (CDT).

10. Allan to go through all the Non-standard ICD10 Diagnoses to see if any of them need to be included in the APACHE II codings for chronic conditions or admit diagnoses.

11. Regarding decision made last time on if/when/how to code elevated platelets -- Allan has updated the page on Essential thrombocythemia/thrombocytosis to describe/explain coding of elevated platelets.

12. We agreed to cease coding of routine swabbing for COVID-19.

13. JALT issues -- including leftover ones from before, and new ones:

  • Visit_Admit_DtTm differences within same admission - Update/reminder about when Visit Admit DtTm in Cognos is DIFFERENT for records included within a single hospitalization. Julie to forward next few of these to Tina who will analyze them, and if it seems they're an ADT/Cognos error it may require reporting it to be fixed to Charity.
  • Reminder about ambiguity in the ICD10-based algorithms Allan created for the APACHE Acute Diagnoses. Allan checked and fixed them, and sent the updated file to Julie and Tina, who will check if these are now finalized.
  • Update/reminder about patients (ICU>Medicine) with very short LOS. Julie did an analysis and found that virtually all of these with LOS of 15 mins or less died. Increasingly as these short LOS grow longer (say to 1-2 hrs) the % who die falls. We hypothesize that for those who don't die but have LOS<2 hrs that most are getting sent from Medicine to ICU or being transferred to a different hospital. To check this out Julie will itemize, separately for Med and ICU, the dispositions of patients with LOS of 2 hrs or less who didn't die.

14. Next Task meeting September 28 at 11 am

ICU Database Task Group Meeting – August 24, 2022

  • Present: Allan, Julie, Tina, Lisa, Mailah, Gail, Pam, Pagasa, Val, Brynn, Michelle
  • Minutes prepared by: AG
  • Action items in BOLD

1. Allan reported having heard nothing more yet about Shared Health helping us move hosting by Digital Health forward.

2. Update on moving to automated identification of the five APACHE II comorbid conditions. Status is Julie to email Allan a final set of questions, before Julie implements it, backdating to 1/1/2019.

3. Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. Update regarding the universal, unique patient identifier in Cognos, ClientGUID. Tina reports she is working on it.

5. Regarding transfer ready issues -- everything is done except some decisions about reporting. Julie, Allan, Tina met and finalized this. See notes in Transfer Delay.

6. Update on new lab listings, which appear to duplicate prior listings. Nothing new to report, Allan to discuss with Dr. Sokoro.

7. Regarding the new decision (see July 13 minutes) to NOT allow someone with Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15 not yet on dialysis to also be coded as having acute renal failure either as an ICD10 code (Concept:Acute renal failure) or as regards APACHE II (ARF (APACHE)) .

  • After further discussion it was agreed not to implement any cross-checks around this. Thus this should now be disseminated to all collectors and implemented.

8. Discussion about when to use Post COVID-19 condition vs. Past history of Covid-19 infection

  • It was clarified that Past history of Covid-19 infection is a comorbid diagnosis that we use to keep track of people who have had COVID-19 in the past, but it's currently inactive. While Post COVID-19 condition is used to indicate an ongoing sequelum of having had COVID-19 in the past (e.g. pulmonary fibrosis, brain fog, etc).

9. Discussion about whether we still want/need to code the Previous Service field, in light of the fact that since Randy Martens retired nobody has asked for this information. Allan asked Bojan and Jodi, who agreed that we do not need this data item --> so we will cease collecting it.

10. Other new questions/issues:

  • Allan to go through all the Non-standard ICD10 Diagnoses to see if any of them need to be included in the APACHE II codings for chronic conditions or admit diagnoses.
  • Q: How should we code cystic hygroma and subdural hygroma?
  • Q: How should we code VEXAS Syndrome (Vacuoles E1 ubiquitin UBA1 gene on the X chromosome Autoinflammation Somatic mutations). It's a rare, predominantly-male, newly-described (in 2020), genetic abnormality that can cause inflammation in numerous different places along with a variety of hematologic abnormalities. It's diagnosed with genetic testing.
  • Q: Should we, and if so how should we, code elevated platelet counts not due to Essential thrombocythemia/thrombocytosis?
  • A: High platelets are an extremely common laboratory finding. It's only rarely due to Essential thrombocythemia/thrombocytosis and instead is almost always a reactive change due to bone marrow stimulation from any number of stimuli. Reactive thrombocytosis is rarely a clinical issue of importance except in the very rare case that the platelet counts >1 million when blood viscosity may rise leading to thromboembolism, strokes, TIA, and other problems of vascular congestion. There is an ICD-10 code for "Reactive thrombocytosis" (D75.81) that we aren't currently using and don't want to add since as above it's rarely a clinical problem of relevance. And our code Disease of blood or blood-forming organ, NOS seems like it might work but again reactive thrombocytosis isn't really a disease. SO, the thrombocytosis not due to Essential thrombocythemia/thrombocytosis should only be coded at all if it is directly causing a clinical problem (as above) and then code the clinical consequence (such as a DVT) combined with Disease of blood or blood-forming organ, NOS.

11. JALT issues -- including leftover ones from before, and new ones:

  • Visit_Admit_DtTm differences within same admission - Update/reminder about when Visit Admit DtTm in Cognos is DIFFERENT for records included within a single hospitalization. Julie to forward next few of these to Tina who will analyze them, and if it seems they're an ADT/Cognos error it may require reporting it to be fixed to Charity.
  • Reminder about ambiguity in the ICD10-based algorithms Allan created for the APACHE Acute Diagnoses. Allan checked and fixed them, and sent the updated file to Julie and Tina, who will check if these are now finalized.
  • Update/reminder about patients (ICU>Medicine) with very short LOS. Julie did an analysis and found that virtually all of these with LOS of 15 mins or less died. Increasingly as these short LOS grow longer (say to 1-2 hrs) the % who die falls. We hypothesize that for those who don't die but have LOS<2 hrs that most are getting sent from Medicine to ICU or being transferred to a different hospital. To check this out Julie will itemize, separately for Med and ICU, the dispositions of patients with LOS of 2 hrs or less who didn't die.

12. Next Task meeting September 7 at 11 am

ICU Database Task Group Meeting – July 13, 2022

  • Present: Allan, Julie, Tina, Lisa, Mailah, Gail, Pam, Pagasa, Barret, Val, Gladys, Pam
  • Minutes prepared by: AG
  • Action items in BOLD

1. Allan reported that he asked Bojan today to ask Perry again about Shared Health helping us move hosting by Digital Health forward. Awaiting more information from Bojan/Perry -- Bojan indicated that Perry indicated at end of June that it’s being looked it “actively” (whatever that means).

2. Update on moving to automated identification of the five APACHE II comorbid conditions. Status is Julie and Tina are working through a final inconsistency related to immunocomprimise, before Julie implements it, backdating to 1/1/2019.

3. Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. Update regarding the universal, unique patient identifier in Cognos, ClientGUID. Tina reports she is working on it. - 2022-08-09 now being collected; needs to be added to CFE and sending still.

5. Update regarding rule in template Template:ICD10 Guideline Transplant Failure in relation to ICD10 codes for transplant rejection. Specifically, to eliminate the guideline that says: If you use this code, you should not also code the comorbid diagnosis for past history of the transplant. Julie identified that in the past 3 yrs there have been 354 T86.x codes (i.e. transplant failure or rejection) -- 30 as acquired, 105 as admit and 219 as comorbids.

  • Julie reports the software is made and for the approximately 100 records that need fixing, Pagasa is doing them manually.

6. There was more discussion about the Transfer Delay issues. Julie reports that there are still some differences and some collectors are looking at them. Julie indicated that she has some questions about how to report this information, and it was decided that this will be discussed at the next JALT meeting.

7. Update on new lab listings, which appear to duplicate prior listings. Allan reported that he emailed Dr. Sokoro for a name of someone at DSM who can clarify how these 11 new listing may relate to those labs we currently collect/count.

8. We revisited the question of whether someone with Chronic kidney disease (end-stage renal/kidney disease, ESRD), Stage 5, GFR LT 15 not yet on dialysis should be allowed to also have a coding of acute renal failure.

  • As we previously discussed, such people are perilously close to needing dialysis and if they live long enough all will progress to needing it. Thus, since a majority of such people who have deterioration of renal function don’t have ARF, but rather just progression of their chronic disease, we generally shouldn’t also code ARF in these cases. BUT, this issue not only comes up in diagnosis coding, but also in APACHE II scoring, where the presence of ARF doubles the number of renal points. And we really need these two aspects of coding to be the same.
  • Accordingly, we tentatively agreed to change the rule such that a person with CRF Stage 5 isn’t allowed to have ARF either as regards ICD-10 coding OR APACHE scoring. But there are possibly other crosschecks or codings that this may affect, so before implementing this rule, Tina will check on such potential complications.

9. New question: How to code foot drop?

  • Answer consistent with ICD-10 is to include it as part of Joint disorder, nontraumatic NOS, rather than add the code specific for this entity. Allan altered that Wiki page to indicate that it includes foot drop and wrist drop.

10. New question: If a patient has a UTI with one organism, and then grows another bug in the urine from a later urine culture, should this be coded as a different UTI?

  • Answer: Especially in patients with Foleys, growing bugs in the urine may or may not indicate the presence of a UTI. The way urine colonization is usually differentiated from UTI is from presence of WBC in the urine, and the organism colony counts. Thus the ultimate answer here is that clinical judgement (on the part of the clinical team, and the data collector) is required.

11. New issue: Code for Disorder of vein, NOS (I87.9) lists alternative diagnoses which have their own codes and so shouldn’t be included here. It was requested that Allan identify them, so they can be listed in the Wiki page for I87.9.

12. New issue: Interplay between regional ischemia and the corresponding regional atherosclerosis. Example is Limb ischemia (upper or lower) and Atherosclerosis of arteries of arms or legs

  • Answer goes beyond just the limbs, and should incorporate any regional ischemia.
  • Ischemia is an acute manifestation of arterial problems that can be from atherosclerosis or other causes (e.g. arterial throboembolism, compartment syndrome, physical compression, pressor agents, and other things.
  • Thus an ischemia code should be used if ischemia exists but coding atherosclerosis (which is a chronic condition) may or may not go along with it.
  • Allan has updated the Template:ICD10 Guideline ischemic gut and inserted these ideas into the new Template:ICD10 Guideline Regional Ischemia

13. Report on the JALT meeting items that occurred prior to today’s Task Group meeting:

  • Apparently it is not uncommon (up to 10-15% in ICUs) for the Service tmp entry to be before the prior Dispo DtTm. This doesn’t occur within Cognos, but can occur when collectors alter incorrect accept or discharge time based on chart data. As the current rule is that collectors only alter such times if they’re off by >30 minutes, most of the resulting “negative” intervals found by Pagasa using link_suspect_negative_transit_time query are <30 mins.
    • The biggest problem here is postoperative patients with times in OR not being appropriately included in Cognos.
    • We decided that:
      • (a) the crosscheck for such “negative” intervals will be altered by Tina to only highlight those that exceed negative 30 minutes - done in Centralized data front end.accdb Change Log 2022 #2022-07-13
      • (b) when those occur Pagasa will not just check them against EPR and change them based on that but instead query collectors for “the truth”, and
      • (c) hoping that ‘a’ will greatly reduce the # of such crosschecks, we will have Pagasa report on this issue in about 6 weeks.
  • Visit_Admit_DtTm differences within same admission - Julie reported that sometimes the Visit Admit DtTm in Cognos is DIFFERENT for records included within a single hospitalization. This is clearly an error. To figure it out, the next few times Julie sees such a problem she’ll forward them to Tina, who’ll analyze the reason(s). This may be an ADT/Cognos error and it may require reporting it to be fixed to Charity.
  • There was discussion about ambiguity in the ICD10-based algorithms Allan created for the APACHE Acute Diagnoses
    • Allan checked and fixed them, and sent the updated file to Julie and Tina
    • Notes on some choices made in doing this -- so we can remember why it was done this way:
      • For the postop diagnoses which include an admit diagnosis and a CCI code: Reasoning that since these cases must be postop (i.e. preICU location is OR or PACU), the choice was made for procedures only to require the 1st 3 digits (i.e. organ) and not "what was done on it". While this choice may overcount it seems likely that allowing only certain of digits 4/5 would undercount even more.
      • Example for craniotomy for malignancy: our version of CCI doesn't include digits 6/7 (which are the ones which specify craniotomy), so it seems sufficient to require a brain tumor admit diagnosis, patient to be postop, and the organ of the admit procedure done be brain components.
  • Over several meetings we discussed whether or not to include "wasted bed-days in ED while on our service" in the calculations of wasted bed-days, defined as bed-days while in ICU on our service but after being designated as transfer ready to a lower level of care (remembering that level of care while in ED is taken as the level of the service caring for them).
    • There are arguments on both sides of this: (i) is we seek only to count wasted hospital bed days, then we'd exclude ER days, (ii) but on the other hand, in using wasted bed-days as an argument that we need more hospital beds, it would seem relevant to include ER days.
    • Julie did some analysis which showed that: (a) in ICU such wasted bed-days were very few, and (b) while in Medicine they were somewhat more common, they were a small fraction of the total wasted bed-days.
    • Based on this, we decided to INCLUDE such wasted bed-days.
  • Question arose that there are some patients (ICU>Medicine) with lengths of say of just a few minutes. We hypothesized that these are mainly people who die very soon after arriving in ICU or ward. Indeed a quick check of a handful of them showed that all were of this type.
    • Before going further, Julie is going to collate, for 2019-2021, the number of such people, separately in Medicine and ICU, and identify the fraction of them with a dispostion of death. We expect almost all of these are deaths very quickly after admission.
  • Question arose of if/how to include lost/discontinued records in our various reports and analyses. As there are only a handful of these per year, we decided to EXCLUDE them from all reports/analyses.
  • There was discussion about the Minimal Dataset:
    • As the reason for creating this preliminary data is "early reporting", we agreed that: (a) there is no need to go beyond Cognos in obtaining this information, and (b) there is no need to do any data checks on it, or for it to be vetted.
      • Tina will change the Wiki in this regard
      • Lisa will notify collectors
    • We also agreed to add previous location to the Minimal Dataset, and again, to just take for this whatever is in Cognos. If it's blank in Cognos, we'll leave it blank for the Minimal Dataset.

14. Next Task meeting August 10 at 11 am

ICU Database Task Group Meeting – June 22, 2022

  • Present: Allan, Julie, Tina, Lisa, Stephanie, Joyce, Mindy, Brynn, Mailah, Gail, Pam, Pagasa
  • Minutes prepared by: AG
  • Action items in BOLD

1. Allan reported that he asked Bojan today to ask Perry again about Shared Health helping us move hosting by Digital Health forward. Awaiting more information from Bojan/Perry.

2. Change for Apache Chronic to ICD10 from separate variable - Update on moving to automated identification of the five APACHE II comorbid conditions. Tina reported that she is working on this. We agreed that this will be backdated to 1/1/2019, i.e. when we began using ICD10 coding.

3. Location metadata storage - Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

4. ClientGUID field - Update regarding the universal, unique patient identifier in Cognos, ClientGUID.

  • Tina reports she needs to give this more thought.

5. Update regarding rule in template Template:ICD10 Guideline Transplant Failure in relation to ICD10 codes for transplant rejection.

  • We want to eliminate the guideline that says: If you use this code, you should not also code the comorbid diagnosis for past history of the transplant. Julie identified that in the past 3 yrs there have been 354 T86.x codes (i.e. transplant failure or rejection) -- 30 as acquired, 105 as admit and 219 as comorbids.
  • Before moving forward on it and fixing the template Allan and Julie will soon chat about the programming logic to fix these going backwards.

6. Transfer Delay - There was more discussion about the transfer delay issues. Tina and Julie are working on this.

7. We reviewed and dealt with a number of outstanding questions.

8. Update on new lab listings, which appear to duplicate prior listings. Allan will contact Dr. Sokoro at DSM to clarify how these 11 new listing may relate to those labs we currently collect/count.

4. ClientGUID field - Update regarding the universal, unique patient identifier in Cognos, ClientGUID.

  • Would be convenient for us and we want to use it to replace both pseudoPHIN and PersonID, except that we don’t have it for records entered manually by data collectors.
  • Tina will inquire with Chastity about this.

5. Update regarding rule in template Template:ICD10 Guideline Transplant Failure in relation to ICD10 codes for transplant rejection.

  • We want to eliminate the guideline that says: If you use this code, you should not also code the comorbid diagnosis for past history of the transplant. Julie identified that in the past 3 yrs there have been 354 T86.x codes (i.e. transplant failure or rejection) -- 30 as acquired, 105 as admit and 219 as comorbids.
  • Before moving forward on it and fixing the template Allan and Julie will chat about the programming logic to fix these going backwards.

6. Controlling Dx Type for ICD10 codes - Barret updated the group on his first path through all our ICD10 codes to identify those that should NOT be allowed in the 3 bins (comorbids, admit dx, acquired dx). He’s about 40% through the listings.

7. There was more discussion about the transfer ready issues. There will be a smaller working group meeting on this June 8.

8. Update on new lab listings, which appear to duplicate prior listings. Allan reported that Dr. Sokoro, his contact at DSM, is away until next week, after which Allan will contact him to clarify how these 11 new listing may relate to those labs we currently collect/count.

9. Next Task meeting June 16 at 10:30 am

ICU Database Task Group Meeting – May 4, 2022

  • Present: Allan, Lisa, Brynn, Michelle, Julie, Pam, Tina, Gail, Val, Gladys, Pagasa
  • Minutes prepared by: AG
  • Action items in BOLD

1. Allan updated the group about asking Shared Health to help us move hosting by Digital Health forward. At a Zoom meeting about this on May 2, including Allan, Shelley Irvine Day, others from SH and DH, it was again recognized that we need Perry Gray to take this to the SH Executive. To that end, Bojan Paunovic asked Perry about the status. Perry replied that he will address it this week. It is not completely clear what form this will take, so we’ll have to wait and see. Awaiting more information from Perry.

2. Update on replacing Accept DtTm with first Service tmp entry, and Arrive DtTm with first Boarding Loc. Tina reports this is now essentially completed.

3. Update on moving to automated identification of the five APACHE II comorbid conditions. Tina reported that she is working on this.

4. Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

5. New item. After discussion we agreed that we no longer need the DC Treatment field and will stop collecting it. Tina has removed it from collection

6. New item: Unique patient identifiers.

  • Manitobans have PHIN; non-Manitobans have a pseudoPHIN. In addition, everyone has a PersonID. These latter two are created for the database and thus have no external existence, i.e. could not be used to link our data to other data. Also, it requires both a consistency check and Pagasa to ensure that the pseudoPHIN and PersonID are consistent across the entire database.
  • Cognos has a universal, unique code called the ClientGUID and as such it could be a very convenient replacement for both pseudoPHIN and PersonID, and allow for linkage to other datasets -- except that we don’t have it for records entered manually by data collectors (instead of using Cognos data as the starting point). This latter occurs mainly for all IICU patients (as they’re not on the “patient follow” method of assigning collectors) and for a smattering of others (likely <25/year). We agreed that we will replace pseudoPHIN and PersonID with the ClientGUID if we can secure a reliable method of filling it in for records entered manually.
    • To this end, Tina will inquire with Chastity.
    • If it turns out we can do it then:
      • Tina has in mind a workaround for the IICU patients
      • Tina will implement automated entry of ClientGUID from Cognos -- and then its absence will indicate to Pagasa those we need to fill in manually.
      • Tina/Julie will update the ClientGUID backwards to the start of its existence, and to the extent possible connect it to pseudoPHIN and PersonID prior to that.
  • We’ll discuss this more next time.

7. New item. We recognized the inconsistency of an item in the template Template:ICD10 Guideline Transplant Failure regarding ICD10 codes for transplant rejection. Specifically we agreed to eliminate the guideline to: If you use this code, you should not also code the comorbid diagnosis for past history of the transplant. In order to help guide us whether to try and fix this going backwards, Julie will obtain a count of the number of persons with codes for transplant rejection.

8. Update on new lab listings, which appear to duplicate prior listings. After the regular meeting today, Allan, Julie and Tina discussed these. Allan has identified 11 new lab listings that may (or may not) relate to the lab counts we collect.

  • Tina has sent Allan the official DSM codes for the labs we collect -- and thereafter Allan will contact DSM to clarify how these 11 new listing may relate to them.

9. Next Task meeting May 18 at 11 am

ICU Database Task Group Meeting – April 19, 2022

  • Present: Allan, Lisa, Brynn, Julie, Pam, Tina, Sherry, Gail, Mindy, Val, Mailah
  • Minutes prepared by: AG
  • Action items in BOLD

1. Update on new lab listings, which appear to duplicate prior listings. Tina will send Allan an updated list of these (done) and he’ll contact the lab this week.

2. Update on asking Shared Health to help us move hosting by Digital Health forward. There is a Zoom meeting about this scheduled May 2 including Shelly Irvine Day to talk about it further, but prior to that Allan will ask Bojan to send to Perry a request for an update (done). Awaiting more information from Perry.

3. Updates on two data change issues: (a) moving to automated identification of the five APACHE II comorbid conditions, and (b) replacing Accept DtTm with first Service tmp entry, and Arrive DtTm with first Boarding Loc.

  • The status of making these changes are similar, i.e. that there are many Wiki pages and other data-related issues that have to be identified and modified before going live with these 2 changes. Tina is working on them.
  • Allan reported that after talking with Carmen and Bojan, they desire to have reporting on transfer delays (including out of ED) altered to be as follows:
    • Reporting on all 3 of these items (transfer out of ED, transfer out of ICU, transfer out of ward) to be the same.
    • At today’s meeting we made some decisions, but on April 27 Julie and Allan had additional discussion and these will be done as indicated herein, in which (unlike the prior decision, we will include, not exclude, delays <30 mins)
    • For transfer out of ED delays report as follows: total # of patients who left alive and admitted to hospital; distribution of TRUE transfer delays [i.e. from transfer-ready until they left]; average value of the TRUE delay; cumulative true delays
    • For delays in transfer out of ICU or ward, report both of the following:
      • Total # of patients who left alive to a lower level of care -- among these provide distribution of true transfer delays [from transfer-ready until they left to lower level, considering leaving to lower level without a noted transfer ready date/time as 0 delay]; average value of true delay; cumulative true delays AND also report #of people who had a transfer ready date/time to lower level but in fact went to a higher or same level instead AND also report #of people who had a transfer ready date/time to lower level but in fact died before going anywhere
      • same as above except restricted to those with transfer delays >2 hrs (ICU) and >4hrs (ward)
  • Sherry identified that the ward attendings at Grace are generally not putting a date/time alongside their notes (and orders) indicating a patient is transfer ready to a lower level of care. Allan let Nick and Ebi know this April 21 in hope they can get it to change, so that they can then have more accurate transfer delay data -- Nick indicated he will try and work with them on this.

4. Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports no new progress.

5. Final discussion about how to code if someone has a limb or organ removed during this stay but before they become our patient, in light of the fact that we already have a group of “Past history of” ICD10 codes for this. See April 6 minutes for decisions on this item.

  • Remaining is to modify the guidelines for Admit Procedure. This has now been done.

6. After further discussion, we agreed that instead of creating new location items of hospital-specific procedure locations, we already have a location item ("Other Procedure Location") that we will use for both previous locations and disposition locations. Tina has made this happen.

7. New item: whether to allow/disallow duplication of diagnoses. This arose with a patient who had two separate skin infections during a single admission. After discussion we agreed to allow this, and remove the crosscheck disallowing it. Tina has disabled query check_ICD10_duplicates.

8. New item: when should Liver enzymes, elevated (liver function tests) be used, as opposed to Disorder of liver, NOS? Discussion highlighted:

  • In general, coding abnormal laboratory findings is optional when the specific cause is known and coded.
  • In the absence of knowing the specific cause, the choice of using the code for abnormal lab test versus a nonspecific diagnosis code (e.g. Disorder of liver, NOS) should mainly be guided by whether or not the other coded diagnoses are present.
    • Example: COVID is associated with elevated LFTs in about 30% of cases. Thus if that is the only recognized reason for the elevated LFTs, then it makes most sense to code and link the COVID diagnosis and the abnormal labs together (instead of using the Disorder of liver, NOS code).

9. Next Task meeting May 4 at 11 am.

ICU Database Task Group Meeting – April 6, 2022

  • Present: Allan, Mindy, Gladys, Mailah, Stephanie, Julie, Tina, Val, Pam, Pagasa
  • Minutes prepared by: AG
  • Action items in BOLD

1. Instructions_for_importing_a_batch_of_DSM_Data#Check_for_new_labs - Update on new lab listings, which appear to duplicate prior listings. Nothing new to report.

2. Update on what Shared Health is planning with regards to the databases. Allan reported that he resent to Perry Gray the most recently requested document about this. Awaiting more information from Perry. Tina reported that through the ticket about this she put in to Digital Health awhile ago, apparently they are deciding on who should be the “owner” of the database.

3. Update on agreement to move to automated identification of the five APACHE II comorbid conditions. So, collectors will no longer be specifically identifying these once Julie/Tina implement this change.

4. Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina reports that Chastity gave her a data sample from Cognos and that Tina/Julie to go over it.

5. More discussion about how to code if someone has a limb or organ removed during this stay but before they become our patient, in light of the fact that we already have a group of “Past history of” ICD10 codes for this. We agreed on the following:

  • As per the existing guidelines, those “Past history of” codes will remain restricted to comorbid diagnoses.
  • In coding an admission which is directly related to a prior procedure:
    • We will expand the guidelines for Admit Procedure. Specifically, to the existing 48 hour rule we will add “OR -- irrespective of whether it's within 48 hours (this could be outside of current hospitalization), if the association of that procedure with the admission is abundantly obvious (as per data collector discretion)”
    • We recognize and accept that since there is no linking of diagnoses with procedures, and in light of restricting “Past history of” diagnosis codes to comorbid diagnoses, such a relationship will be suggestive, not explicit.
  • Example: Patient had a BKA before ICU admission (either before hospital admission, or during this hospital admission), and then develops a wound infection from the amputation site with sepsis. Past history, loss of limb(s) should be a comorbid diagnosis. The CCI code for the amputation should be an Admit Procedure, and the diagnosis would be Iatrogenic, infection, following a procedure or surgery, NOS .

6. More discussion about replacing Accept DtTm with first Service tmp entry, and Arrive DtTm with first Boarding Loc

  • A canvassing of collectors indicates that the Service tmp and Boarding Loc entries are likely MORE accurate that are the Accept DtTm and Arrive DtTm fields.
  • Julie informed the group that per old guidelines, before calculating statistics on discharge/transfer delays, she substracts 2 hrs for ICU and 4 hrs for wards.
    • Apparently, this was in order to account/adjust for procedural delays (e.g. room cleaning, transport, etc) in moving patients.
    • As many/most of those sorts of delays ARE modifiable, it’s not clear if this practice should continue.
    • Allan queried Bojan Paunovic, Carmen Hrymak and Ebi Renner to ask about how they prefer this in the future. The consensus answer is to report both:
      • (a) total # of patients who left alive; the distribution of TRUE transfer delays [i.e. from transfer-ready until they left]; and the average value of the TRUE delay
      • (b) same as 'a' except restricted to those with transfer delays >2 hrs (ICU) and >4hrs (ward)
    • Tina will implement an automatic data check (soft check) for such delays <30 mins, and in calculating the statistics on such delays, Julie will ignore them if <30 mins.
  • Once all this is done, we will make the switchover, ceasing to collect Accept DtTm and Arrive DtTm fields.

7. Further discussion about recording Drug-induced immunosuppression, particularly as part of the APACHE comorbidity

  • As per before, this is now going to be collected exclusively under ICD10 code Z92.25 Past history of immunosuppressive drugs or corticosteroids. Lisa to notify collectors about this.
  • Of note, there’s no real reason to convert over the prior incarnations of collecting this as a CCI/TISS item, as in any case it exists as a created variable, not a hard-coded variable.

8. Next Task meeting April 20 at 11 am

ICU Database Task Group Meeting – March 9, 2022

  • Present: Allan, Julie, Lisa, Tina, Pam, Pagasa, Barret, Pam, Stephanie, Mailah
  • Minutes prepared by: AG
  • Action items in BOLD

1. Update on new lab listings, which appear to duplicate prior listings. Nothing new to report.

2. Update on what Shared Health is planning with regards to the databases. Allan reported that as requested, he provided Perry with a document (from Tina) a technical description of what is needed. Awaiting more information from Perry.

3. Update on agreement to move to automated identification of the five APACHE II comorbid conditions. So, collectors will no longer be specifically identifying these once Julie/Tina implement this change. See also point (7)

4. Location metadata storage - Regarding creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina/Julie to implement this, but Tina recently recognized that Cognos contains this information and before implementing it using info supplied by collectors, she has asked Chastity about obtaining it from Cognos instead.

5. Question from list: How to code if someone has a limb or organ removed during this stay but before they become our patient?

6. Question from list: Change to replace Accept DtTm with first Service tmp entry, and Arrive DtTm with first Boarding Loc

  • We want to finally retire arrive time and accept time, replacing them with info from the Boarding Loc and Service temp. But Julie notes that we use these data to calculate and report on ER delays, and that in comparing the old with new way methods she has found some inconsistencies. So, before we completely make the changeover,
    • At the next task meeting Julie will show us histograms comparing the two sets of data
    • Lisa will look at the inconsistencies and see if she can figure out why it’s happening

7. Question from list Drug-induced immunosuppression.

  • Tina made the point that the way we’re currently recording this entity for purposes of Chronic Health APACHE is as a TISS element, but that this is awkward and suboptimal.
  • After discussion we agreed to instead collect this information under existing code Z92.25 Past history of immunosuppressive drugs or corticosteroids, and for that purpose Allan has changed the definition of that ICD-10 code, which is applicable to both ICU and wards. Lisa to notify collectors of this. Tina to update the created variables queries to reflect this.

8. Next Task meeting April 6 at 11 am

ICU Database Task Group Meeting – February 17, 2022

  • Present: Allan, Julie, Sherry, Lisa, Tina, Pam, Pagasa, Mindy, Brynn, Barret
  • Minutes prepared by: AG
  • Action items in BOLD

1. Update on new lab listings, which appear to duplicate prior listings. Allan has begun working on this. Nothing new to report.

2. Update on what Shared Health is planning with regards to the databases. Allan reported that as requested, he provided Perry with a document (from Tina) a technical description of what is needed. Awaiting more information from Perry.

3. Change for Apache Chronic to ICD10 from separate variable - We agreed to move to automated identification of the five APACHE II comorbid conditions. So, collectors will no longer be specifically identifying these. Julie/Tina to implement this change.

4. Update on the approximately 200 database questions that have been assigned for assessment but not addressed.

  • Tina reports this list is down to about 120 now.
  • After discussion, we agreed to delay aggressively addressing these until our data collectors come back from their COVID assignments.

5. Location metadata storage - Update on creating new table containing information (metadata) about individual medicine wards (including High Obs). Tina/Julie to implement this. It will require that data collectors notify Julie and/or Tina and/or Pagasa when a specific ward is altered in such ways.

6. New questions:

7. Next meeting March 9 at 1pm.

ICU Database Task Group Meeting – February 3, 2022

  • Present: Allan, Julie, Sherry, Lisa, Tina, Val, Pam, Pagasa, Mindy
  • Minutes prepared by: AG
  • Action items in BOLD

1. Update on new lab listings, which appear to duplicate prior listings. Allan has begun working on this. Nothing new to report.

2. Update on what Shared Health is planning with regards to the databases. Allan reported that as requested, he provided Perry with a document (from Tina) a technical description of what is needed. Awaiting more information from Perry.

3. Update on plan (4/15/2021 Task meeting) to implement automatic coding of APACHE comorbidities

  • Allan is working on refining the ICD10 codes.

4. Further consideration of T19 - Spontaneous breathing via ETT without PEEP/CPAP, with or without supplemental O2 (TISS Item) and T20 - Supp O2 through any device, delivered via nose, mouth, ETT or trach (TISS Item).

  • The original TISS28 item (CCM 24(1):64-73,1996) of supplemental ventilatory support, worth 2 points, is either of: (a) Breathing spontaneously via ETT without PEEP/CPAP, or (b) Supplemental O2 by any method without mechanical ventilation (invasive or noninvasive)
    • So there’s some overlap here (which is OK since it’s a single TISS item) in that spontaneous breathing via ETT without PEEP/CPAP but with supplemental O2 fits into both ‘a’ and ‘b’
  • On 6/15/2021 we changed TISS19 and TISS20 to:
    • TISS19 = Spontaneous breathing via ETT without PEEP/CPAP, with or without supplemental O2 -- e.g. includes trach mask, T-tube
    • TISS20 = Supplemental O2 though any device, delivered via nose, mouth, ETT or trach [which must be without invasive or noninvasive mechanical ventilation]
    • However, at that time we incorrectly said that TISS19 is just 1 point, while in fact it should be 2 points (and TISS20 is 2 points also)
  • There is still overlap between these versions of TISS19 and TISS20, specifically: breathing via ETT with O2 but without PEEP/CPAP fits both -- but this is not a problem, as when one computes the TISS score for a given domain (e.g. respiratory support), only the single item with the highest point score is counted.
  • Allan suggests that we:
    • Clarify TISS20: Supplemental O2 though any device, delivered via nose, mouth, ETT or trach, without invasive or noninvasive mechanical ventilation
    • Modify TISS19: Spontaneous breathing via ETT without PEEP/CPAP, with or without supplemental O2, without invasive or noninvasive mechanical ventilation
    • Ensure that TISS19 and TISS20 both are 2 points

5. Update on the approximately 200 questions that have been flagged for assessment but not addressed.

  • Lisa dealt with approximately 40 of these, and referred approximately 70 of them to Julie and Pagasa.
  • The remainder were either assigned to others, or unassigned. Lisa will categorize them into into 3 groups: Need to be addressed; Can be deleted from further consideration; Unclear.

6. A clarification was made in the Wiki regarding Medical Assistance In Dying (Z51.81). Specifically that it should not be coded in a record if the patient was transferred to a different institution to undergo MAID -- instead it should be coded at that other institution.

7. It was agreed to stop the manual notation made in the Boarding Loc comment field for COVID patients or those on COVID wards.

8. Clarification of coding for iatrogenic pneumothorax.

  • The issue was that in coding iatrogenic PTX, the instructions are to combine: Iatrogenic, puncture or laceration, related to a procedure or surgery NOS along with one of the nontraumatic PTX codes. BUT all of the latter indicated not to use them for iatrogenic or traumatic causes --- and this was WRONG. The relevant Wiki pages have now been changed to say not to use them for traumatic pneumothorax, but that can be used for iatrogenic PTX.

9. After extensive discussion it was agreed to create a new table containing information (metadata) about individual medicine wards (including High Obs). This additional layer will be used to keep track over time of: bed count, ward type (specifically general ward vs. high obs) and other information. We recognize this will increase the work that Julie has to do for reporting on unit-specific information, but it provides flexibility for future. See Location metadata storage for further info. Tina/Julie to implement this. It will require that data collectors notify Julie and/or Tina and/or Pagasa when a specific ward is altered in such ways.

10. An example was raised that a patient went medicine ward --> endoscopy --> OR --> surgery ward; but there was no appropriate Dispo location from the medicine ward. After discussion, we agreed to add to Dispo locations for each hospital a listing such as: HSC, Procedure location, NOS. Tina to implement this; this is also mentioned at Medical_Assistance_In_Dying#Collection_Instructions_for_MAID so any update needs to fix that as well..

ICU Database Task Group Meeting – January 6, 2022

  • Present: Allan, Julie, Sherry, Lisa, Stephanie, Tina, Val, Pam, Mailah, Mindy
  • Minutes prepared by: AG
  • Action items in BOLD

1. Update on new lab listings, which appear to duplicate prior listings. Allan has begun working on this. Nothing new to report.

2. Update on what Shared Health is planning with regards to the databases. Allan reported that as requested, he provided Perry with a document (from Tina) a technical description of what is needed. Awaiting more information from Perry.

3. Update on plan (4/15/2021 Task meeting) to implement automatic coding of APACHE comorbidities. Allan is working on refining the ICD10 codes.

4. Update on the decision from 11/30/2021 meeting to revert to the old system, of starting a new record (with new APACHE score and new admit diagnoses) with service changes. This has been done, with relevant changes to the Wiki and “unwinding” of the 10 records that contain such MICU to SICU or SICU to MICU transfers into separate records.

5. Allan reported that he is working on drafting a Data Sharing Agreement that all users of line-level (i.e. individual record) data will need to complete to obtain such data. Draft version is in Database_Request_Process#Data_Accessibility_and_Responsibility. Work is ongoing on this. Also, a decision will need to be made about whether we need a similar agreement for users of cumulative/aggregate data.

6. Discussion about the Minimal Data Set and reporting. We agreed:

  • We will retain the 11 elements of the “true” minimal dataset, all of which come from Cognos.
  • Going forwards, all reporting by Julie will consist of details only from completed records, along with information about what % and # of records for the time interval are incomplete as of the time of the reporting.
  • Lisa will let all collectors know of this change
  • Tina has updated Minimal Data Set regarding it
  • Allan will let Bojan know -- done.

7. There is a new ICD10 code U07.5 Past history of Covid-19 infection which is meant to be used just like the other “Past history of…” codes. Lisa to let all collectors know about it.

8. After discussion we agreed that there is no further need for the Wiki page "HSC Boarding Locations". Tina has deleted it.

9. The question was raised about definition of Emergency Surgery (concept). After discussion we agreed to maintain it as is, i.e. admitted from Operating Room or Recovery AND surgery was classified as E1. Tina has updated wiki Emergency Surgery (concept), Emergency Surgery (TISS Item) and Admit Type for APACHE II to make sure this is defined consistently.

10. There is confusion about TISS elements T19 - Spontaneous breathing via ETT without PEEP/CPAP, with or without supplemental O2 (TISS Item) and T20 - Supp O2 through any device, delivered via nose, mouth, ETT or trach (TISS Item) .

  • This issue tracks back to the 6/15/2021 and 7/8/2021 minutes where indeed the current versions of TISS#19 and TISS#20 were chosen, both as 2 points, in order to correlate correctly to the original/actual delineation of TISS. So, no changes needed for these.

11. Tina identified that there are approximately 200 database questions that have been assigned for assessment but not addressed. Lisa will go over this list and categorize them into 3 groups: Need to be addressed; Can be deleted from further consideration; Unclear. We’ll discuss this further next meeting.

12. Next meeting February 3, 2022 at 11 am.
