The 'usual care' of major depression in primary care practice.

OBJECTIVE
To determine how primary care physicians treat patients with major depression in the course of routine practice and the degree to which such practice produces outcomes anticipated with interventions recommended by the Agency for Health Care Policy and Research Depression Guideline Panel.


DESIGNS
Prospective cohort study.


SETTINGS
Academically affiliated ambulatory family practice centers and internal medicine clinics in urban neighborhoods of Pittsburgh, Pa.


PATIENTS
Ninety-two patients who were seen in primary care practices and who met criteria for a current major depression as determined by the Diagnostic Interview Schedule and a psychiatrist's assessment.


INTERVENTION
Physicians were informed of the patient's psychiatric diagnosis, and were urged to treat it in whatever manner and for whatever duration they deemed appropriate (ie, with "usual care").


MAIN OUTCOME MEASURES
The treatments that were provided, the patients' clinical course, and the relationship between the type of treatment and clinical course.


RESULTS
Health center records indicated that 67 patients (73%) received a depression-specific treatment in the 8 months following study entry. A majority of the total cohort were prescribed an antidepressant drug. Of the 92 patients, 18 (20%) were asymptomatic at 8 months (Hamilton Rating Scale for Depression score, < or = 7). The treatment pattern was not clearly related to the clinical course.


CONCLUSIONS
The recovery rates for the patients with major depression who were treated with usual care in routine primary care practices were lower than those anticipated from treatments consistent with the Agency for Health Care Policy and Research guidelines. Further studies of the caregiving elements that influence the effectiveness of depression-specific treatments of patients in primary care settings are needed.
