LENGTH OF STAY in all medicine wards per HOSPITAL ADMISSION

  • Default form:

Usually used in aggregate form as "per location" and/or "per 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 Laptop 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 Laptop Admission

Exclusion Criteria

None

Frequency

  • Reported when patient had been discharged out of Medicine.
  • Monthly, quarterly, year based on discharged date of Dispo DtTm

Definition and Derivation

  • Calculate the LOS - see 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 time frame.

Report Users

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

"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?

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 hospital stay. Patient’s stay to different services within the hospital were linked and cumulative LOS only in the medicine wards was calculated.

Two approaches to link patient's admissions within a 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 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 .

The second approach has been used and the criteria to determine a new admission are the following:

  1. Patient who has first and only admission
  2. Patient who left the hospital against medical advice (AMA) ( Med Var 6), from previous admission
  3. When patient is transferred to a different hospital, the admission for that 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 hospital < 1 day because the bed is usually put on hold on the first hospital)
  4. Patient with previous encounter and now admitted from ER, home/long term care facility, outside city or province
  5. 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
  6. Patient who was previously discharged to OR/RR and now admitted from OR/RR for more than 7 days from previous discharge date
  7. 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
  8. Patient previously discharged to a ward and now admitted from a ward but the ward locations are now the same
  9. None of the above but the gap in time between the two admissions is >90 days.

Elements used in linking admissions

  1. PHIN, Last Name, First Name
  2. Hospital/Site
  3. Ward/ICU location
  4. ‘Admit From’ location
  5. ‘Discharge To’ location
  6. Admit date and time
  7. Discharge date and time
  8. Med Var 1, Med Var 2, Med Var 6
