Psychiatric and Medical Diagnoses as Risk Factors for Mortality in Psychiatric Patients: A Case-Control Study. .

On the basis of a case-control study, the authors conclude that former psychiatric inpatients are more likely than control subjects to die of both natural and unnatural causes within 2 years of discharge. Patients who committed suicide were more likely to have had a diagnosis of affective disorder (unipolar depression) or alcoholism. Those who died of natural causes were more likely to have been admitted with medical diagnoses; no specific psychiatric diagnoses were associated with these deaths. It is doubtful that medical illnesses caused psychiatric syndromes such as depression in these inpatients. Psychiatric and medical illnesses combined may increase a patient's likelihood of seeking psychiatric help and entering the hospital. [ABSTRACT FROM AUTHOR]
