Effects of medical illness and somatic symptoms on treatment of depression in a family medicine residency practice.

The specific aims of this pilot study were to describe the treatment received by depressed patients in a family practice residency setting and to compare treatment modalities and intensity of treatment between patients with and without medical illnesses. A 12-month chart audit of a cohort of 340 patients randomly sampled from a family practice waiting room for a previous study revealed a 1-year period prevalence for diagnosed depression of 10.3% (35 patients). No patient met DSM-III-R criteria for major depressive disorder and yet 57% received tricyclic antidepressant therapy and 60% were eventually referred for specialist mental health care. Tricyclic therapy and follow-up visits for depression were less likely to take place for patients with more severe medical illnesses or high levels of somatic symptoms. These findings suggest that patients in primary care settings may have depressive symptoms severe enough to provoke tricyclic therapy or referral but do not meet current diagnostic criteria. Furthermore, medical illness and somatic symptoms may deleteriously affect treatment in primary care patients. Additional prospective research is needed to determine appropriate criteria for treatment of depressive symptoms in primary care patients and to evaluate the effects of medical illness and somatic symptoms on treatment by primary care physicians.

Functional versus structural social support and health care utilization in a family medicine outpatient practice.

Three hundred forty-three family-practice patients were surveyed by questionnaire and medical record audit to evaluate the relationships between social support and medical care utilization. Social support was not associated with laboratory test ordering. The mean number of office visits per year was higher for patients with low versus high confidant support (4.71 vs. 3.81, P less than 0.10) and affective support (5.21 vs. 3.60, P less than 0.05). Mean total charges in 1 year were higher for patients with low versus high confidant support ($232 vs. $148, P less than 0.05) and affective support ($244 vs. $154, P less than 0.05). Poor confidant and affective support were both associated with longer visits. Structural measures of social support were not related significantly to any utilization indicator. These findings were maintained in multiple-regression models controlling for physical health and seven demographic characteristics. Second-order regression models revealed interaction by race, employment status, and sex. Blacks showed no effect of confidant support on office visits. Poor confidant support resulted in $201 more in total charges for the unemployed (P = 0.003) versus $49 more for the employed (P = 0.15). Women with low affective support had $119 more in charges (P = 0.001) versus $16 less for men (P = 0.82). The results suggest that low functional social supports are important determinants of increased medical service utilization and that they may have differential effects by race, sex, and employment status, all of which should be considered independently in future studies.

The effect of a telephone family assessment intervention on the functional health of patients with elevated family stress.

A randomized trial of a telephone family assessment intervention was conducted during a 2.5 month period on 224 ambulatory primary care patients, aged 18-49 years, who were selected according to self-report of elevated family stress levels. Family physicians conducted telephone interviews to collect information from patients on their supportive and stressful family members. The working hypothesis was that this process would lead to reduction in the patient's family stress and to improvement in family support and personal health status. Patients reported that the intervention caused them to think about their family support and helped them to feel better. Comparison of family factor and functional health scores before and after intervention also indicated a limited beneficial effect, but only for a small subset of black patients. These results suggest that the telephone family assessment alone is inadequate as an intervention and should be strengthened to include professional assistance to patients for the family problems that are identified by the assessment.

The Duke-UNC Functional Social Support Questionnaire. Measurement of social support in family medicine patients.

A 14-item, self-administered, multidimensional, functional social support questionnaire was designed and evaluated on 401 patients attending a family medicine clinic. Patients were selected from randomized time-frame sampling blocks during regular office hours. The population was predominantly white, female, married, and under age 45. Eleven items remained after test-retest reliability was assessed over a 1- to 4-week follow-up period. Factor analysis and item remainder analysis reduced the remaining 11 items to a brief and easy-to-complete two-scale, eight-item functional social support instrument. Construct validity, concurrent validity, and discriminant validity are demonstrated for the two scales (confidant support--five items and affective support--three items). Factor analysis and correlations with other measures of social support suggest that the three remaining items (visits, instrumental support, and praise) are distinct entities that may need further study.

Does a coexisting anxiety disorder predict persistence of depressive illness in primary care patients with major depression?

We assessed whether a coexisting anxiety disorder predicts risk for persistent depression in primary care patients with major depression at baseline. Patients with major depression were identified in a 12-month prospective cohort study at a University-based family practice clinic. Presence of an anxiety disorder and other potential prognostic factors were measured at baseline. Persistent depressive illness (major depression, minor depression, or dysthymia) was determined at 12 months. Of 85 patients with major depression at baseline, 43 had coexisting anxiety disorder (38 with social phobia). The risk for persistent depression at 12 months was 44% greater [Risk Ratio (RR) = 1.44, 95% confidence interval (CI) 1.02-2.04] in those with coexisting anxiety. This risk persisted in stratified analysis controlling for other prognostic factors. Patients with coexisting anxiety had greater mean depressive severity [repeated measures analysis of variance (ANOVA), p < 0.04] and total disability days (54.9 vs 19.8, p < 0.02) over the 12-month study. Patients with social phobia had similar increased risk for persistent depression (RR = 1.40, 95% CI 0.98-2.00). A coexisting anxiety disorder indicates risk for persistent depression in primary care patients with major depression. Social phobia may be important to recognize in these patients. Identifying anxiety disorders can help primary care clinicians target patients needing more aggressive treatment for depression.
