Depression decision support in primary care: a cluster randomized trial.

BACKGROUND: Intensive collaborative interventions improve depression outcomes, but the benefit of less intensive interventions is not clear. OBJECTIVE: To determine whether decision support improves outcomes for patients with depression. DESIGN: Clinician-level, cluster randomized, controlled trial. SETTING: 5 primary care clinics of 1 Veterans Affairs medical center. PARTICIPANTS: 41 primary care clinicians, and 375 patients with depression (Patient Health Questionnaire [PHQ-9] depression scores of 10 to 25 or Hopkins Symptom Checklist-20 [SCL-20] scores > or = 1.0). MEASUREMENTS: The primary outcome was change in depression score (SCL-20) at 6 and 12 months. Secondary outcomes were health-related quality-of-life (36-item Short Form for Veterans [SF-36V] score), patient satisfaction, antidepressant use, and health care utilization. INTERVENTION: Clinicians received depression education and were randomly assigned to depression decision support or usual care. The depression decision support team, which consisted of a psychiatrist and nurse, provided 1 early patient educational contact and depression monitoring with feedback to clinicians over 12 months. RESULTS: Although SCL-20 depression scores improved in both groups, the intervention had no effect compared with usual care. The difference in slopes comparing intervention and control over 12 months was 0.20 (95% CI, -0.37 to 0.78; P = 0.49), which was neither clinically nor statistically significant. Changes in SF-36V scores also did not differ between groups. At 12 months, intervention patients reported greater satisfaction (P = 0.002) and were more likely to have had at least 1 mental health specialty appointment (41.1% vs. 27.2%; P = 0.025), to have received any antidepressant (79.3% vs. 69.3%; P = 0.041), and to have received antidepressants for 90 days or more (76.2% vs. 61.6%; P = 0.008). LIMITATIONS: Usual care clinicians received depression education and had on-site mental health support, which may have mitigated intervention effectiveness. CONCLUSIONS: Decision support improved processes of care but not depression outcomes. More intensive care management or specialty treatment may be needed to improve depression outcomes.

Use of videoconferencing for depression research: enrollment, retention, and patient satisfaction.

The goal of this study was to describe the effects of using videoconferencing on participant enrollment, research measure administration and responses, study retention, and satisfaction. We recruited 400 patients from the Portland Veterans Affairs Primary Care Clinics for a randomized clinical trial of a care management intervention for depression. Patients recruited from distant clinic sites had the option of traveling to Portland, Oregon, for initial interviews or being interviewed using videoconferencing. Interviews included obtaining informed consent and administration of research measures. Remote participants were subsequently asked to complete a 12-item mail survey regarding the interview. There were no significant problems with the process of interviewing and obtaining informed consent by videoconferencing, as reported by patients and clinic staff. Twenty of the 31 participants interviewed by videoconferencing returned the satisfaction questionnaire. Participants indicated a high degree of satisfaction with these interviews, and expressed willingness to recommend videoconferencing to others. No differences were observed between the Patient Health Questionnaire depression scores of videoconferencing and in-person participants, and there was no significant difference in the 6-month rate of loss to follow-up in the randomized trial. Videoconferencing allows patients in rural and remote locations to participate in psychiatric research and expands sources of recruitment for research projects.

Screening for depression and suicidality in a VA primary care setting: 2 items are better than 1 item.

OBJECTIVE: To evaluate the psychometric properties of a single-item depression screen against validated scoring algorithms for the Patient Health Questionnaire (PHQ) and the utility of these algorithms in screening for depression and suicidality in a Department of Veterans Affairs (VA) primary care setting. STUDY DESIGN: Recruitment phase of a randomized trial. METHODS: A total of 1211 Portland VA patients with upcoming primary care clinic appointments were administered by telephone a single item assessing depressed mood over the past year and the PHQ. The PHQ-9 (9 items) encompasses DSM-IV criteria for major depression, the PHQ-8 (8 items) excludes the thoughts of death or suicide item, and the PHQ-2 (2 items) assesses depressed mood and anhedonia. Patients whose responses suggested potential suicidality were administered 2 additional items assessing suicidal ideation. Patients receiving mental health specialty care were excluded. RESULTS: Using the PHQ-9 algorithm for major depression as the reference standard, the VA single-item screen was specific (88%) but less sensitive (78%). A PHQ-2 score of > or =3 demonstrated similar specificity (91%) with high sensitivity (97%). For case finding, the PHQ-8 was similar to the PHQ-9. Approximately 20% of patients screened positive for moderate depression, 7% reported thoughts of death or suicide, 2% reported thoughts of harming themselves, and 1% had specific plans. CONCLUSIONS: The PHQ-2 offers brevity and better psychometric properties for depression screening than the single-item screen. The PHQ-9 item assessing thoughts of death or suicide does not improve depression case finding; however, one third of patients endorsing this item reported recent active suicidal ideation.

Effects of a depression education program on residents' knowledge, attitudes, and clinical skills.

OBJECTIVE: To determine whether an interactive educational program would improve obstetrics and gynecology residents' knowledge, attitudes, confidence, and skills in caring for depressed patients. METHODS: We recruited 74 residents from eight residency programs to attend the Depression Education Program, which consists of a 1-hour lecture and two 2-hour workshops combining discussion, diagnosis and treatment tools, critique of a videotape, practice with feedback, and audiotape self-assessment. Before and after the program, participants 1) completed a questionnaire measuring knowledge, attitudes, and reported actions taken with a recent depressed patient; 2) received a standardized patient visit; and 3) kept lists of patients they suspected were depressed. Clinic patients completed a depression screening questionnaire. To assess improvement, we used paired t tests, McNemar chi2 tests, and multivariate models adjusting for training site. RESULTS: The education program led to 3-month improvements in participants' reported use of formal diagnostic criteria (38% before, 66% after; P =.004), clinical actions documented for suspected depression (P =.035), and perceived self-efficacy in depression care (P <.001). Perceived preparedness to diagnose depression, treat with medications, and comanage with a mental health practitioner improved (P <.05 for each). Small improvements in clinical behaviors with standardized patients and clinic-based depression detection rates were not statistically significant. CONCLUSION: The Depression Education Program improved residents' knowledge, confidence, and reported clinical actions with depressed patients, but did not improve most objectively assessed outcomes.

Worklife and satisfaction of general internists.

BACKGROUND: Prior studies have reported relatively low job satisfaction for general internists. We used data from a large US physician survey to assess correlates of satisfaction of general internists. METHODS: The Physician Worklife Survey was mailed to a national random stratified sample of 5704 US physicians. General internists were assessed for their satisfaction, training, patient mix, work hours, the likelihood of recommending their specialty to medical students, and job stability. We then compared them with a specialist sample (internal medicine subspecialists [IMSSs]) and a primary care sample (family physicians [FPs]). Logistic regression was used to model predictors of satisfaction, stress, and medical student recruitment. RESULTS: There were 2326 respondents (adjusted response rate, 52%): 450 (19%) were general internists; 502 (22%), FPs; and 438 (19%), IMSSs. General internists were less satisfied than were IMSSs with their relationships with colleagues and with patient care issues (P<.01 for both) and less satisfied than were FPs with community ties (P =.001). Global job, career, and specialty satisfaction were significantly lower for general internists vs FPs and IMSSs (P<.05). General internists spent proportionately more of their work week in the hospital than did FPs (20% vs 13%; P<.001) and more time providing outpatient care than did IMSSs (56% vs 42%; P<.001). General internists had more patients with complex medical and psychosocial problems than did FPs (P<.01) but fewer patients with complex medical problems than did IMSSs (P<.001). Higher satisfaction for general internists was associated with older physician age, less time pressure during office visits, fewer work hours, and fewer patients with complex psychosocial problems (P<.05 for all). General internists were less likely than were FPs to recommend their specialty to medical students (P<.001). Specialty satisfaction, female gender, and control of hassles predicted medical student recruitment by general internists. CONCLUSIONS: General internists' role of caring for patients with complex problems is associated with lower levels of satisfaction than for IMSSs and FPs. Adjusting caseload for patient complexity, expanding time for office visits, and additional training in the care of patients with psychosocially complex problems may improve the job satisfaction of general internists and medical student recruitment into the specialty.

Measuring adherence to depression treatment guidelines in a VA primary care clinic.

The primary objectives of this pilot study were to develop a measure of adherence for depression practice guidelines and to assess the degree to which providers and patients adhere to guidelines in a VA primary care setting. The Depression Guideline Measure (DGM) is based on three national guidelines. The DGM was used to review medical records of 111 patients with Patient Health Questionnaire (PHQ) scores >or=10. Interrater reliability for 15 of 19 DGM checklist items was excellent (kappa > 0.75). There was a broad range of adherence to guideline criteria: only 13.5% of patients were contacted for follow-up within 2 weeks, while 100% of providers documented follow-up plans. Forty percent of patients saw mental health providers, and 63% were prescribed antidepressants. A secondary objective of the study was to explore the relationship between guideline adherence and changes in PHQ scores. Among 51 patients who completed follow-up PHQs, no associations were detected. The results suggest that the DGM shows promise as a reliable measure of guideline adherence and that guideline criteria are frequently not met in busy primary care clinics. More research is needed to determine the validity of the DGM and the impact of guideline adherence on depression outcomes.

Radiologist uncertainty and the interpretation of screening.

OBJECTIVE: To determine radiologists' reactions to uncertainty when interpreting mammography and the extent to which radiologist uncertainty explains variability in interpretive performance. METHODS: The authors used a mailed survey to assess demographic and clinical characteristics of radiologists and reactions to uncertainty associated with practice. Responses were linked to radiologists' actual interpretive performance data obtained from 3 regionally located mammography registries. RESULTS: More than 180 radiologists were eligible to participate, and 139 consented for a response rate of 76.8%. Radiologist gender, more years interpreting, and higher volume were associated with lower uncertainty scores. Positive predictive value, recall rates, and specificity were more affected by reactions to uncertainty than sensitivity or negative predictive value; however, none of these relationships was statistically significant. CONCLUSION: Certain practice factors, such as gender and years of interpretive experience, affect uncertainty scores. Radiologists' reactions to uncertainty do not appear to affect interpretive performance.
