Prevalence and course of psychiatric disorders among nursing home admissions.

Several studies have shown that psychiatric disorders are common in nursing homes, but information on the course of psychiatric morbidity shortly after admission is still lacking. Therefore, we interviewed 262 residents of Austrian nursing homes within 2 weeks following admission, and a second time after 6 months. Using the Clinical Interview Schedule and its case criteria, prevalence was 76.3% at admission, and 69.9% 6 months later. In the intervening period, the mortality rate was markedly higher among psychiatric cases, and the incidence of new psychiatric cases (5.9%) was slightly lower than the rate of remission (8.6%). At both assessments, organic mental illness was the most frequent diagnosis. Nursing home residents suffering from psychiatric disorders were treated predominantly by general practitioners applying a psychotropic drug regimen.
