Description |
The indicator measures the risk-adjusted rate of readmission following discharge for a mental illness. Note |
Calculation: Description |
Risk-adjusted rate for each region = Observed number of readmissions in each region ÷ Expected number of readmissions in the region × Canadian average readmission rate Unit of Analysis: Episode of care An episode of care refers to all contiguous inpatient hospitalizations in general and psychiatric hospitals and all day surgery visits regardless of diagnoses. To construct an episode of care, a transfer is assumed to have occurred if the following condition is met:

Rationale |
Readmission to inpatient care may be an indicator of relapse or complications after an inpatient stay. Inpatient care for a person living with a mental illness aims to stabilize acute symptoms. Once stabilized, the individual is discharged, and subsequent care and support are ideally provided through outpatient and community programs in order to prevent relapse or complications. High rates of 30-day readmission could be interpreted as a direct outcome of poor coordination of services and/or an indirect outcome of poor continuity of services after discharge. |
Interpretation |
Lower rates are desirable. |

Trending Issues |
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was implemented in the Ontario Mental Health Reporting System as of 2016-2017. Prior to 2016-2017, the fourth edition (DSM-IV-TR) was used. Due to the fact that the DSM-IV-TR and DSM-5 diagnostic categories are not fully comparable, there may be some shift in the distribution of cases across categories. Therefore, trending of 2015-2016 and 2016-2017 rates for Ontario may potentially be affected. |
Comments |
A 30-day readmission can occur in the same facility as the index episode or in a different facility. A readmission can be a planned or unplanned admission. Planned versus unplanned admissions cannot be distinguished in all available data sources. For jurisdictions where comprehensive information was available, rates including both planned and unplanned readmissions and only unplanned readmissions were compared, and they were not statistically significantly different. Published work has shown that few planned readmissions for mental illness within 30 days are scheduled by practitioners. |
