Depression in primary care: changes in pattern of patient visits and complaints during a developing depression.

The purpose of this study was to characterize changes in patient behavior associated with a developing depression. The records of 154 depressed patients from a solo family practice were examined for type and number of complaints, number of visits, and amount of hospitalization during two periods of time. In addition, 154 patients were used as controls and matched to the depressive patients by age, sex, and season of year seen. Two similar time periods were examined in the controls. The depressed group in comparisons both with itself and with the control group showed, in the seven months prior to the diagnosis of depression, these changes: (1) increase in number of patient-initiated office and home visits; (2) increased incidence of hospitalization; and (3) increased number of presenting complaints of three types: ill-defined "functional" complaints; pain of undetermined etiology in a wide variety of sites: head, chest, abdomen, and extremities; and "nervous" complaints, mainly increased tension and feelings of anxiety. The study results indicate that increased number of office visits and "functional" somatic complaints or anxiety-tension feelings should suggest depression.
