Transfer Delay (Medicine)
Transfer Delay is the difference between Dispo_DtTm and #Time patient is ready for transfer in decimal days. Other terms use to call it are Beds Occupied by transferable patients, Wasted Beds, Avoidable Days.
|Indicator:||Transfer Delay (Medicine)|
|Reports:||Directors Quarterly and Annual Report (Medicine)|
- "created" is not in the list (Created, Raw) of allowed values for the "IndicatorCreatedRaw" property.
- Default form:
See also Transfer Delay (Critical Care).
- The purpose is to determine the amount of time a patient is occupying a bed in at a given Level of care (High Observation ward or a regular ward) when the patient is no longer needing that Level of care.
- This is relevant because:
- If patients are at a higher level of care than they need this can indicate that beds at a lower level are not available and more might be needed.
- It might also indicate that beds at a higher (and more expensive) level of care might be reduced if patients could consistently move to the appropriate level of care.
- A patient who doesn't need to be in a hospital runs the risk of nosocomial complications if they remain in hospital.
- Transfer Delay is the difference in decimal days between the time the pt is first transfer ready at a Level of care and the time that they leave that level
- starts at the Transfer Ready DtTm corresponding to the first Boarding Loc of a given Level of care
- ends as a patient leaves that level of care in one of the following ways:
Time patient is ready for transfer
The definition of this has changed between before and after PatientFollow Project.
Starting Oct 1, 2020, it will need to be calculated differently.
It is not reported by ward, it is reported only per episode / profile.
Julie sums up the multiple transfer delays that might be present and reports them all aggregated to their Dispo DtTm. It is done this way because only once we have a complete record with a Dispo DtTm we have reliable Transfer Ready data, so it's the only way we can report on this without becoming inconsistent with data reported earlier.
Start time is first transfer ready per level of care; end is either last of this level of care, or dispo.
- Before Oct 1, 2020, it is calculated by Created_Variables_Common_maker query and stored in Created_Variables_Common table in CFE.
- Starting Oct 1, 2020, it will be added but haven't started.
Implementation in CFE
For now, a "Transfer Ready Med testing" button on the main form of CFE needs to be pressed to generate this data. Once we are comfortable with it this generating will be included in the "calc created variables" button.
Sub populate_created_transferDelay() loads created_TransferReady query (which generates transfer ready dates) and created_BoardingLoc_plus_historical query and writes delays to created_transferDelay table.
Which Transfer Ready DtTm To Use?
Admit DtTm or Dispo DtTm < 2020-10-01 00:00
- for each patient in ICU and Medicine ward, the transfer date and time is taken from the Transfer Ready DtTm field.
Admit DtTm or Dispo DtTm >= 2020-10-01 00:00
- the transfer date and time is taken from the Transfer Ready DtTm tmp entry.
- for each record, it is possible to have one or more entries of Transfer Ready DtTm corresponding to one or more boarding locations, which may or may not be at a different level in the Level of care hierarchy, namely regular wards (CTU or NTU) and High-Obs Wards
- for the purpose of Transfer Delay (Medicine), we will have a transfer delay for each group of Boarding Locs at the same level of care, i.e. there may be more than one per CCMDB record. To accommodate more than one line per record, this is stored in its own table.
- the first Transfer Ready DtTm from a Boarding Loc with the same level of care will be used
Calculation when transfer time missing
|legacy info, expand to see details - we have updated the data with an imputed time component for old transfer ready entries that only had a date.|
This is as per approval by Dr. Dan Roberts.
Reporting of Transfer Delays
- Include all cases with transfer ready dttm (who went to same/lower/higher level of care or died).
- Refer to indicator Beds occupied by transferrable patients
