Calculation Methods

Readmission rate is calculated as the number of patients readmitted within 30 days of discharge divided by the number of patients discharged during the study period.

OMHRS and CIHI/DAD databases are used to identify index as well as subsequent hospitalizations for mental health and addictions.

Numerator (short description i.e. not inclusions/exclusions)

Number of individuals with any MHA hospital readmissions* within (≤) 30 days following the incident hospital discharge in the reporting period.

For any MHA hospital discharge (denominator), calculate the following readmissions (numerator):

Any MHA Admission during follow-up period:

DAD ICD-10-CA Dx10Code1: F04 to F99,
or OMHRS DSM-IV: Any hospital admission (including missing diagnosis except for DSM-IV 290.x. 294.x in AXIS1_DSM4CODE_DISCH1)

Denominator (short description i.e. not inclusions/exclusions)

Total number of incident MH&A hospital discharges in the reporting period.

Incident = 1st event in a calendar period without any look-back for past events (If multiple hospital visits in CY, use first). Keep only one discharge person per year.

MH&A Hospital Discharges:

From DAD var DX10CODE1 with any of the following ICD-10-CA codes: F04 to F99

From OMHRS:

If var AXIS1_DSM4CODE_DISCH1 complete* use AXIS1_DSM4CODE_DISCH1
