Reasons for Admissions or Visit

Nearly one third (31%) of all mental illness-related hospitalizations were related to mood disorders such as major depressive disorder or bipolar disorder, followed by substance-related (other than overdose) admissions (17%). Looking at specific diagnostic codes by age group shows the most common admissions among youth are for severe depressive episodes, while in adults 65-74 and 75+ delirium is the most commonly identified diagnosis. In adults 20 to 44, the most common diagnosis is for paranoid-type schizophrenia, and among those 45-64, alcohol withdrawal state was the most common diagnosis among Simcoe Muskoka residents.


Among emergency department visits related to mental illness, anxiety disorders were identified as the most probable diagnosis in over one third (38%) of visits, followed by substance-related (other than acute overdose) visits (22%) and mood disorders (17%). The most common diagnoses in Simcoe Muskoka residents were unspecified anxiety disorder, unspecified depressive episode, acute stress reaction and acute intoxication and harmful use of alcohol. Among children and youth (ages <1 to 19), acute stress reaction was the most commonly diagnosed reason for mental illness-related emergency room visits, while unspecified anxiety disorder was the most common diagnosis in all other age groups.
