Prevalencia de trastornos psiquiátricos en hombres y mujeres hospitalizados en un servicio de medicina interna de un hospital de Santiago de Chile / Prevalence of psychiatric disorders among subjects hospitalized in a medicine ward of a general hospital

ABSTRACT

Background: Mental disorders may interfere, aggravate or mimic medical conditions. Aim: To study the prevalence of psychiatric disorders among patients hospitalized in a medical ward of a general hospital. Patients and methods: A structured interview for DSM-III, devised for "non patients", was applied to 203 men and 203 women, aged 11 to 90 years old, hospitalized in an internal medicine service of a public hospital. Thirty four psychiatric conditions that can be discriminated with the instrument and others that complied with DSM-III criteria, were investigated. Results: There was a 60 percent prevalence of mental disorders among men (alcohol dependency in 26 percent, delirium or dementia in 10.8 percent, anxiety disorders in 10.4 percent, major depression in 7.8 percent and adaptation disorders in 3 percent). Among women, the prevalence of mental disorders was 65 percent (major depression in 23.2 percent, anxiety disorders in 14.3 percent, adaptation disorders in 8.4 percent, dementia in 5.6 percent, delirium in 3 percent and alcohol dependency in 2.5 percent). Most conditions were of moderate or mild intensity. Two or more conditions coexisted in 40 percent of cases. Only in 8 percent of these subjects, a psychiatric consultation was requested. Conclusions: There is a high frequency of psychiatric disorders among medical patients. These must be adequately diagnosed and treated
