Psychiatric consultation among hospitalized arthritis patients.

Fifty consecutive psychiatric consultations on 48 patients over an 18-month period in an arthritis hospital are analyzed. The range of psychiatric disorders and their relationship to characteristics of the patient population, such as age, sex, and medical diagnosis, are described. Approximately 2% of patients admitted to the hospital during this period elicited psychiatric consultation. This rate is one-third of the consultation rate of an acute medical and surgical hospital serviced by the same consultants. The relative distribution of psychiatric diagnoses--depression 59%, personality disorders and drug abuse 15%, psychosis 10%, conversion reaction 10%, and "other" 6%--was similar to that encountered in an acute general hospital setting. Although depression was the most prevalent psychiatric problem, it was severe enough to elicit consultation only in 1% of the total hospitalized population; its severity did not correlate directly with the severity of rheumatoid arthritis, the most common medical diagnosis encountered. Neither a particular medical illness nor sex accounted for a disproportionate share of the psychiatric consultations.
