Calculation: Description
Table Cell (td)

Risk-adjusted rate for each facility = Observed number of readmissions for each facility ÷ Expected number of readmissions for the facility × Canadian average readmission rate

Unit of Analysis: Episode of care

An episode of care refers to all contiguous inpatient hospitalizations and same-day surgery visits. For episodes with transfers within or between facilities, transactions were linked regardless of diagnoses. To construct an episode of care, a transfer is assumed to have occurred if either of the following conditions is met:

a) An acute care hospitalization or a same-day surgery visit occurs less than seven hours after discharge from the previous acute care hospitalization or same-day surgery visit, regardless of whether the transfer is coded

b) An acute care hospitalization or same-day surgery visit occurs between 7 and 12 hours after discharge from the previous acute care hospitalization or same-day surgery visit, and at least one of the hospitalizations or visits has coded the transfer

For episodes of care that involved transfers, readmissions were attributed to the last hospital from which the patient was discharged before readmission.

Rationale
Table Cell (td)

Urgent readmissions to acute care facilities are increasingly being used to measure institutional or regional quality of care and care coordination.

Readmission rates can be influenced by a variety of factors, including the quality of inpatient and outpatient care, the effectiveness of the care transition and coordination, and the availability and use of effective disease management community-based programs. While not all unplanned readmissions are avoidable, interventions during and after a hospitalization can be effective in reducing readmission rates.
