psychiatric case fatality
The proportion of individuals with a psychiatric disorder who die within a specified time period.
Full Definition
Psychiatric case fatality refers to the proportion of individuals diagnosed with a specific psychiatric disorder who die within a defined time period, typically one year. This measure differs from general mortality rates by focusing specifically on the subset of the population with psychiatric conditions. Case fatality rates in psychiatry often reflect elevated mortality associated with suicide, medical comorbidities, lifestyle factors, and treatment-related complications. The measure is particularly relevant for severe mental illnesses such as schizophrenia, bipolar disorder, and major depressive disorder, which are associated with increased mortality risk. Calculating psychiatric case fatality requires accurate case identification and comprehensive mortality follow-up, making it challenging but valuable for assessing the public health impact of mental disorders.
Usage
Usage note: Distinguish from 'psychiatric case fatality rate,' which includes the denominator specification.
