psychiatric case fatality rate
The proportion of individuals with a specific psychiatric disorder who die within a defined time period, often used to assess suicide risk.
Full Definition
A measure that quantifies the mortality risk associated with psychiatric disorders by calculating the percentage of diagnosed cases that result in death within a specified timeframe. This rate is particularly relevant in psychiatric epidemiology for conditions with elevated suicide risk, such as major depression, bipolar disorder, or schizophrenia. The case fatality rate helps clinicians and researchers understand the severity and prognosis of psychiatric conditions, inform treatment priorities, and evaluate the effectiveness of intervention programs. It differs from general mortality rates by focusing specifically on individuals with confirmed psychiatric diagnoses.
Usage
Usage note: Not to be confused with general mortality rates in psychiatric populations, which may include deaths from all causes.
