Length of stay in all medicine wards per HOSPITAL ADMISSION

Indicators
Indicator:	LOS Medicine per hospital admission
Created/Raw:	not stated
Program:	Medicine
Start Date:	2003-10-01
End Date:
Reports:	Directors Quarterly and Annual Report (Medicine)

Usually used in aggregate form as "per location" and/or "per reporting timeframe", e.g. month/quarter/year x Ward/Unit x Hospital.

Significance

Length of stay (LOS) is influenced by many factors, but safe and effective care should result in shorter length of stay.

Start Dates

Oct 2003 to Sept 2020 - each record is per ward stay. A hospital stay may have one or more individual ward stay (or records).
Starting Oct 2020- each record is a continuous stay in any locations under Medicine service (or one Medicine episode) - see Definition of a Medicine Program Admission. If the patient is transferred to another service and comes back to Medicine service, this is a new record. A hospital stay may have one or more Medicine episodes.

Sampling Plan / Procedure

Inclusion Criteria

All Medicine admissions - see Definition of a Medicine Program Admission

Exclusion Criteria

None

Frequency

Reported the admission to the Medicine Service ends, ie when there is a Dispo DtTm(Discharge Date)
Monthly, quarterly, year based on discharged date of Dispo DtTm

Definition and Derivation

Calculate the LOS for each record - refer to LOS Per Record
Per patient, identify the records having the same Visit Admit DtTm. This implies same hospital stay or hospitalization.
Per patient per hospitalization, sum up all the LOS Per Record
- It is possible that the same patient may have one or more hospitalization within the same reporting time frame.

Data Source

For dates refer to LOS Per Record
For hospitalization date - use Visit Admit DtTm
For patient identifier - use either Person ID, Chart, PHIN

Reported as

Mean, median, sum, minimum, maximum (in days) per site and/or time frame
N is the number of patient's hospitalizations
Counts and % of N based on LOS groups (<1,1-5,6-10,11-15-16-20,>20) for a given reporting time frame and/or site

 ==Significance==
 Length of stay (LOS) is influenced by many factors, but safe and effective care should result in shorter [[:Category: Length of stay | length of stay]].
-== Definition ==
+==Start Dates==
-Average LOS reported for each ward, for each [[CTU]]/[[NTU]]/[[MU]] and for each [[Site and Location table | hospital]] in the region.
+*Oct 2003 to Sept 2020 - each record is per ward stay. A hospital stay may have one or more individual ward stay (or records).
+*Starting Oct 2020- each record is a continuous stay in any locations under Medicine service (or one Medicine episode) - see [[Definition of a Medicine Program Admission]]. If the patient is transferred to another service and comes back to Medicine service, this is a new record. A hospital stay may have one or more Medicine episodes.
 ==Sampling Plan / Procedure==
 ===Inclusion Criteria===
-All patients admitted to a medical ward. If a patient is admitted to a Medicine service, stayed in one or more Medicine [[Site and Location table | ward]]s or came from/went to ICU and then discharged from the [[Site and Location table | hospital]], the individual length of stays in each of the [[Site and Location table | wards]] will be summed up. The LOS is accounted to the first [[Site and Location table | ward]] the patient was admitted. Movements are monitored between wards and ICUs. See the COMMENT below for details on how to link the flow of movement of patient within the [[Site and Location table | hospital]].
+All Medicine admissions - see [[Definition of a Medicine Program Admission]]
-{{Discuss | who = Julie | question = Does this mean time spent in an ICU between wards is included in the LOS? If not, can we tweak the text so that is clearer? }}
 ===Exclusion Criteria===
-All ICU admissions (e.g. ward patients who went to ICU) while [[Bed holds|beds are put on hold]] in Medicine wards are excluded (because the admission and discharge dates in ICU are within the admission and discharge dates in Medicine [[Site and Location table | ward]]).
+None
-==== Required Variables  (Definition of Terms/) ====
+===Frequency===
-*'''Ward admit date/time''' – the date and time the patient is admitted to a [[Site and Location table | ward]].
+* Reported the admission to the Medicine [[Service tmp entry|Service]] ends, ie when there is a [[Dispo DtTm]](Discharge Date)
-*'''Ward discharge date/time''' – the date and time the patient was discharge to a [[Site and Location table | ward]].
+* Monthly, quarterly, year based on discharged date of [[Dispo DtTm]]
-*'''Ward ''' – the ward(s) the patient was(were) admitted in the [[Site and Location table | hospital]]. The first and last wards must be clearly specified.
-*'''ICU ''' – the ICU(s) the patient was(were) admitted in the [[Site and Location table | hospital]]. The first and last ICUs must be clearly specified.
 ==Definition and Derivation==
-{{Discuss |who=Julie | question = originally you called this "Calculation Procedure:" - which do you prefer? }}
+* Calculate the LOS for each record - refer to [[LOS Per Record]]
+* Per patient, identify the records having the same [[Visit Admit DtTm]]. This implies same hospital stay or hospitalization.
-* '''Individual LOS per ward''' = [[Dispo DtTm]] – {{discuss | is this [[Arrive DtTm]] or [[Accept DtTm]]? }}
+* Per patient per hospitalization, sum up all the [[LOS Per Record]]
-(expressed in days).
+** It is possible that the same patient may have one or more hospitalization within the same reporting time frame.
-* '''LOS per patient''' = sum of individual LOS in all  the wards the patient stayed during a [[Site and Location table | hospital]] stay.
-* '''Ave LOS Per Ward''' = average LOS from all hospital stays over all admissions in each ward, where discharge date of the last service (ward/ICU) is between the beginning and the ending of the reporting time.   The term of reference for the [[Site and Location table | ward]] is the first [[Site and Location table | ward]] the patient was admitted.
-* '''Ave LOS Per [[CTU]]/[[NTU]]/[[MU]]''' = average LOS from all [[Site and Location table | hospital]] stays over all admissions in each [[CTU]]/[[NTU]]/[[MU]], where discharge date of the last service (ward/ICU) is between the beginning and the ending of the reporting time.
-* '''Ave LOS Per [[Site and Location table | Hospital]]''' = average LOS from all hospital stays over all admissions in each [[Site and Location table | Hospital]], where discharge date of the last service (ward/ICU) is between the beginning and the ending of the reporting time.
-== Reported ==
-* Reported:  1)  by [[Site and Location table | ward]] of each [[Site and Location table | hospital]], 2) by [[CTU]]s/[[NTU]]s/[[MU]]s of each hospital, and  3) by hospital in the region.
-* WHERE & WHEN  REPORTED:
-| [[Quarterly report | Quarterly]] and [[Annual report]] in Fiscal Year for Summary of Early Predictor of Adverse Outcome ([[ALERT Scale]]) .
-==Report Users==
-{{Discuss | who = Julie | question =
-[[p:Dr. Dan Roberts]]
-You had this as "PRESCRIBED BY: "; which is not how you set it in [[Template:Reporting Indicators]]. Also, Dan is likely no longer the user of this, so it should probably be updated. If we use a title rather than a name it will be self updating. }}
-== TARGET==
-{{Discuss | who = Julie | question =
-"None yet."
-What does that mean in the context of "Target"? And how does "Target" fit in with the structure you described in [[Template:Reporting Indicators]]?  }}
-==Comment==
-{{Discuss |who=Julie | question = this still talks about TMSX... what is the new status of this field? }}
-The Medicine [[MedTMS]] and Critical [[TMSX]] Databases were combined to determine if a Medicine patient was admitted from ICU and/or have been transferred to ICU during a [[Site and Location table | hospital]] stay.  Patient’s stay to different services within the [[Site and Location table | hospital]] were linked and cumulative LOS only in the medicine wards was calculated.
-Two approaches to link patient's admissions within a [[Site and Location table | hospital]] stay when a patient appeared more than once in the database, '''1)'''  link the admissions if the patient is transferred to or came from an ICU/another ward/went to OR within the [[Site and Location table | hospital]], and do not link if otherwise. '''2)''' do not link the patient if the next admission is a new admission, and do link if otherwise. Both will produce the same results .
+==Data Source==
+* For dates refer to [[LOS Per Record]]
+* For hospitalization date - use [[Visit Admit DtTm]]
+* For patient identifier - use either [[Person ID]], [[Chart]], [[PHIN]]
-The second approach has been used and the criteria to determine a new admission are the following:
+== Reported as==
-# Patient who has first and only admission
+* Mean, median, sum, minimum, maximum (in days) per site and/or time frame
-# Patient who left the hospital against medical advice (AMA) ([[Med Var 6 - AMA | Med Var 6]]), from previous admission
+* N is the number of patient's hospitalizations
-# When patient is transferred to a different [[Site and Location table | hospital]], the admission for that [[Site and Location table | hospital]] ends and the patient becomes a new admission to the second hospital (except if the reason is further lab test and the stay in the second [[Site and Location table | hospital]] < 1 day because the [[Bed holds|bed is usually put on hold on the first hospital]])
+* Counts and % of N based on LOS groups (<1,1-5,6-10,11-15-16-20,>20) for a given reporting time frame and/or site
-# Patient with previous encounter and now admitted from ER, home/long term care facility, outside city or province
-# Patient with previous encounter who was discharged home/long term care facility, outside city or province and now admitted from a service/unit within the hospital
-# Patient who was previously discharged to OR/RR and now admitted from OR/RR  for more than 7 days from previous discharge date
-# Patient who was previously discharged to a ward (not a Medicine ward) and now admitted from OR/RR  for more than 30 days from previous discharge date
-# Patient previously discharged to a ward and now admitted from a [[Site and Location table | ward]] but the ward [[Site and Location table | locations]] are now the same
-# None of the above but the gap in time between the two admissions is >90 days.
-=== Elements used in linking admissions ===
+==SAS Program==
-# [[PHIN field | PHIN]], [[Last Name]], [[First Name]]
