Unrecognized physical illness prompting psychiatric admission: a prospective study

The authors studied 100 state hospital psychiatric patients consecutively admitted to a research ward who were screened to eliminate physical illness before admission. They found an unusually high incidence of medical illness: 46% of these patients had an unrecognized medical illness that either caused or exacerbated their psychiatric illness, 80% had physical illnesses requiring treatment, and 4% had precancerous conditions or illnesses. A workup consisting of psychiatric and physical examination, SMA-34, urinalysis, ECG, and EEG after sleep deprivation identified over 90% of medical illnesses present in this population. The authors suggest that such a battery be part of the routine workup for all hospitalized psychiatric patients.
