1 Hospitalization for Mental Health Disorders Hospitalization for Mental Health Disorders 1 CHA REPORT 2004 Definition/Description: Hospitalization for Mental Health Disorders Mental health disorders were defined according to ICD-9-CM. This includes anxiety disorders, dementia, depression, sonality disorders, schizophrenia, substance abuse and other mental health disorders. This data examines in-patient hospitalization for mental health disorders and therefore represents the incidence of what are likely the most serious mental illnesses in the population. The following data are presented: 1. Mental Health Disorders: and age-adjusted hospitalization rates, and case counts, for females, males, both sexes in the Winnipeg Health Region, annually from 1997/98 to 2002/ Mental Health Disorders: Case counts and age-specific rates of hospitalization for females, males, and both sexes in the Winnipeg Health Region. 3. Mental Health Disorders: Case counts and crude and age-adjusted rates of hospitalization for females, males, both sexes, by Community Area in the WHR, 2002/ Per cent Distribution of Categories of Mental Health Disorders for females, males, and both sexes in the Winnipeg Health Region, 2002/ Per cent Distribution of Categories of Mental Health Disorders by -Sex Groups for Residents of the Winnipeg Health Region, 2002/03. Method Mental Health disorders were defined according to ICD-9-CM codes in the Manitoba Health Discharge Abstract database. Inclusion of a case was based on the diagnosis most responsible for the hospital stay i.e. the diagnosis that is the reason for the greatest proportion of time spent in hospital. One fiscal year of data (2002/03) was used. The denominator was the regional or community area population from the same year. All rates are provided as population. Limitations: This rate reflects the number of visits for in-patient hospital treatment for mental health disorders and therefore does not reflect discrete cases. In other words, one resident could have several hospital visits for treatment of one or more mental health disorders. Therefore, this indicator should not be used as an indicator of prevalence of mental health disorders in the population for the region. It represents the utilization of in-patient hospital-based treatment in the population for mental health disorders.

The rationale for this is that there was very little difference between the crude and age-adjusted rate for each community area and for the region. For comparison purposes, both crude and age-adjusted rates are shown in the Findings section. The crude rate of hospitalization for mental health disorders was 5.95 population in the Winnipeg Health Region in fiscal year 2002/03. The rate for females is similar to that of males: 6.01 and 5.89 population, respectively in fiscal year 2002/03. The highest rate of hospitalization for mental health disorders was found in the 85 years and older age group, at population, in fiscal year 2002/03. The Downtown community area had the highest rate of hospitalization for mental health disorders, at 13.61, which is more than double the rate for the region. However, the rate in this community area should be interpreted with caution, 1 Source of information: Canadian Institute of Health Information (CIHI), QuickStat on-line service:

It is possible that sons in care may contribute more cases to this indicator however their true residence may be elsewhere in the region or province. See Methods. Point Douglas also has a higher rate of hospitalization for mental health disorders, at 8.86 population. The lowest rate is found in Transcona community area, at 2.66 population. Leading causes of hospitalization for mental health disorders: Approximately 65% of all hospitalizations for mental health disorders can be attributed to anxiety disorders, dementia, depression, sonality disorders, schizophrenia and substance abuse. Of these, substance abuse and schizophrenia were the most common. Leading causes of hospitalization for mental health disorders among females differed than those for males. For females, leading causes of hospitalization for mental health disorders were depression, schizophrenia and substance abuse. For males, leading causes of hospitalization for mental health disorders were substance abuse, and schizophrenia. Comparison of CIHI Hospitalization s for Mental Illness or Addiction, 2000/01: the crude rate of hospital separation for mental illness or addiction for the Winnipeg Regional Health Authority is slightly lower than that of Canada. The same can be said for the standardized rates.
