| Patients may show up in our database repeatedly either during the same hospital stay or at a later time. If they show up at a later time, but soon after the last hospital stay, they may qualify as "readmission", which we report monthly, quarterly and annually | | Patients may show up in our database repeatedly. Our [[L_Log]] records are patient-ward-stay based. Once the [[data processor]] completes the [[centralized data Vetting Process]] (i.e. [[PHIN field|PHINs]] are checked and PseudoPHINs are generated) the PHIN field can be used for linking L_Log records for the same patient. This combining data is stored in [[L Person table]] by [[Encounter processing]]. |

| What is the cut-off for continuous stay detection when moving between ICUs and/or wards? E.g. if patient is discharged from one ward at 0800, how late can he arrive at the next ward and still be considered a continuous stay?

| What are the fields that have to match to consider two encounters the same patient?
| | If a patient is never discharged in between L_Log entries it may be a '''[[Continuous Stay]]'''. |

| == Continuous Hospital Stay ==
| | If a patient is discharged and then admitted again at a later time, but soon after the last hospital stay, they may qualify as '''[[Readmission]]'''. |
| The [[statistician]] uses data from [[Admit From & Discharged To]], [[Med Var 1 - Admit-from Ward]] and [[Med Var 2 - Discharge-to Ward]] to
| |
| * link profiles from one ward to another when both wards are within the database program
| |
| * detect a likely continuous stay when a pt is discharged from one of our wards to a non-collected ward and then re-admitted to one of our wards from the same non-collected ward.

| For our purposes, readmissions are admissions of patients who were recorded by our database recently. | | For patients encountered repeatedly some data should be consistent between stays. |

|
| === ICU Definition ===
| | The [[data processor]] runs a set of checks during vetting that attempts to find and make consistent the records for patients encountered previously. |
| For ICU, a readmission is a patient where
| |
| * (admit date/time) - (most recent ICU discharge date/time to ward or home) <= 72 hours
| |
| * is '''not''' admitted for planned and scheduled surgery
| |
| * might be readmitted from Ward or outside hospital
| |
| | |
| === Medicine Definition ===
| |
| For medicine, a readmission is a patient where
| |
| * (admit date/time) - (most recent discharge date/time to the hospital) <= 7 days after their most recent discharge time to the hospital
| |
| * is admitted from outside hospital
| |
| * (Legacy: planned surgery used to be excluded, but this stopped because of insufficient data when we stopped collecting some APACHE elements in the medicine program Dec 31, 2006)
