BACKGROUND: Depression's high prevalence and large amount of potentially modifiable morbidity make it an excellent candidate for quality improvement (QI) techniques. Yet there is little evidence on how to promote adherence to evidence-based guidelines. A locally run research and QI project that was part of a larger National Institute of Mental Health-funded study to implement depression guidelines was implemented by a primary care team at a Department of Veterans Affairs (VA) ambulatory care center in 1997 and 1998. DEVELOPMENT OF THE QI INTERVENTION: The plan to improve screening and recognition entailed systematically screening all patients attending the primary care clinic; sending computer reminders to clerical staff, nursing assistants, and primary care providers; and auditing team performance with monthly feedback. RESULTS: Once the intervention was in place, nearly all patients were screened. The primary care provider documented the assessment of whether a patient was depressed for nearly all patients who screened positive. Few resources were needed to maintain the project once it was implemented. DISCUSSION: An evidence-based QI intervention led to profound and lasting changes in primary care providers' recognition of depression or depressive symptoms. The QI implementation continued for one year after the intervention's end, but a new VA computerized medical record system uses similar computer-generated reminders

Smoking is the main cause of chronic obstructive pulmonary disease (COPD), and smoking cessation is the only effective intervention to slow its progression. We examined whether smokers with COPD received more cessation services than smokers without COPD. Current smokers from 18 Veterans Health Administration primary care clinics completed baseline and 12 month follow-up surveys (baseline n = 1,941; 12 month n = 1,080), composed of validated questions on smoking habits, history, and attitudes; health/functional status; and sociodemographics. Both at baseline and 12 month follow-up, smokers with COPD were more likely to report that they had been advised to quit, prescribed nicotine patches, or referred to a smoking cessation program within the last year. However, the rate of quitting smoking was the same for smokers with COPD and smokers without COPD. The increase in cessation services received by smokers with COPD was noted primarily among smokers not interested in quitting. New approaches may be required, particularly to help smokers not interested in quitting

PURPOSE: To determine the behaviors, knowledge, and attitudes of resident physicians regarding exercise counseling. METHOD: In 1997, a self-administered questionnaire was sent to 313 internal medicine resident physicians at six U.S. training programs. Pearson correlation coefficients examined associations between the resident physicians' practices, attitudes, and personal habits. Stepwise multiple linear regression identified predictors of exercise counseling by the resident physicians. RESULTS: A total of 251 resident physicians responded. Only 15.5% reported counseling more than 80% of the clinic patients about exercise. Over 93% understood the benefits of exercise, and almost all (96%) felt that it was a physician's responsibility to counsel patients about exercise. Only 29% felt successful at getting their patients to start exercising, and only 28% felt confident in their skills to prescribe exercise for patients. Ninety-one percent felt that training in exercise counseling would be worthwhile. The significant predictors of physician exercise counseling were perception of exercise counseling as a priority (p <.001), confidence in exercise-counseling skills (p <.001), and postgraduate year of training (p <.05) (R(2) =.18). The significant predictors of physicians' confidence in exercise-counseling skills included physician's gender (i.e., men) (p <.001), perception that exercise is important for a healthy 35-year-old (p <.01), feeling successful at exercise counseling (p <.001), perceiving less interference with counseling by barriers (p <.001), and prior training in exercise counseling (p <.05) (R(2) =.44). CONCLUSIONS: Resident physicians' perceptions of exercise counseling as a priority, confidence in counseling skills, and postgraduate year of training are important predictors of their providing exercise counseling. These factors should be addressed in future educational programs

BACKGROUND: People who are physically active live longer, but it is unclear whether this is because of physical activity in the distant or more recent past. METHODS: We assessed activity levels in 5209 men and women in the Framingham Heart Study from 1956 to 1958 and again from 1969 to 1973. We included individuals who were alive and without cardiovascular disease in the period 1969 to 1973. The primary outcome was death from all causes during the 16 years after the 1969 to 1973 assessment. Secondary outcomes were incidence and mortality rate of cardiovascular disease. We used Cox proportional hazards regression to calculate the relative risk of being sedentary, both unadjusted and controlling for smoking, weight, systolic blood pressure, cholesterol, glucose intolerance, left ventricular hypertrophy, chronic obstructive pulmonary disease, and cancer. RESULTS: The overall 16-year mortality rate was 37% for men and 27% for women. When both distant and recent activity levels were included along with major cardiovascular disease risk factors, for recent activity the most active tertile had lower overall mortality rate than the least active tertile for men (risk ratio 0.58, 95% confidence interval, 0.43-0.79) and women (risk ratio 0.61, 95% confidence interval, 0.45-0.82). For distant activity there was no difference in overall mortality rate between the most and least active tertiles either for men or for women. Adjusting for major cardiovascular disease risk factors had little effect on the results. CONCLUSIONS: The reduction in overall mortality rates is more associated with recent activity than distant activity. These results suggest that for sedentary patients, it may never be too late to begin exercising

OBJECTIVE: This study assesses the effects of competing demands, such as poor health habits or new medical problems, on health-habit counseling during a primary care visit. METHODS: We surveyed a consecutive sample of 1,259 patients visiting primary care clinicians at an academic VA medical center. Before the visit, patients reported their health status, health habits, and sociodemographics; immediately after the visit, patients reported reasons for the visit and whether they had been counseled about specific health habits. We scored visit acuity ranging from visits for unscheduled walk-in care or new medical problems to scheduled visits for check-ups or old problems. We defined counseling 'triggers' as clinical indications for counseling about particular health habits (e.g., smoking). We developed a logistic model predicting primary care provider counseling during a visit. RESULTS: Over two-thirds of patients (68.9%) received some health habit counseling. Controlling for other independent variables, patients with more triggers were more likely to report being counseled. Counseling rates went up as visit acuity went down; patients with the lowest visit acuity having 67% greater odds of being counseled than patients with the highest visit acuity. CONCLUSIONS: Physicians set priorities for health-habit counseling during a visit based on patients' health habit problems or triggers; whether the visit is scheduled or walk-in; and whether the patient has new or acute problems. Future research about primary care performance of health habit counseling should account for these patient and visit characteristics, and prevention-oriented health care organizations should ensure access to scheduled 'check-up' visits

OBJECTIVE: To evaluate two performance-based measures of functional status and assess their correlation with self-report measures. DESIGN: Cross-sectional study. PARTICIPANTS: Of the 363 community-dwelling elders enrolled in a trial of comprehensive geriatric assessment who participated, all had at least one of four target conditions (urinary incontinence, depression, impaired functional status, or history of falling). MEASUREMENTS: Two performance-based measures, National Institute on Aging (NIA) Battery, and Physical Performance Test (PPT), and three self-report functional status measures, basic and intermediate activities of daily living and the Short-Form-36 (SF-36) physical functioning subscale, were used. Measures of restricted activity days, patient satisfaction and perceived efficacy were also used. MAIN RESULTS: All measures were internally consistent. There was a high correlation between the NIA and PPT (kappa = 0.71), while correlations between the performance-based and self-report measures ranged from 0.37 to 0.50. When patients with values above the median on the two performance-based measures were compared with those below, there were significant differences (p </=.0001) for age, number of medications, and the physical function, pain, general health, and physical role function SF-36 subscales. CONCLUSIONS: Performance-based measures correlated highly with each other and moderately with questionnaire-based measures. Performance-based measures also had construct validity and did not suffer from floor or ceiling effects

The Veterans Health Administration (VHA) Western Region and associated medical schools formulated a set of recommendations for an improved ambulatory health care delivery system during a 1988 strategic planning conference. As a result, the Department of Veterans Affairs (VA) Medical Center in Sepulveda, California, initiated the Pilot (now Primary) Ambulatory Care and Education (PACE) program in 1990 to implement and evaluate a model program. The PACE program represents a significant departure from traditional VA and non-VA academic medical center care, shifting the focus of care from the inpatient to the outpatient setting. From its inception, the PACE program has used an interdisciplinary team approach with three independent global care firms. Each firm is interdisciplinary in composition, with a matrix management structure that expands role function and empowers team members. Emphasis is on managed primary care, stressing a biopsychosocial approach and cost-effective comprehensive care emphasizing prevention and health maintenance. Information management is provided through a network of personal computers that serve as a front end to the VHA Decentralized Hospital Computer Program (DHCP) mainframe. In addition to providing comprehensive and cost-effective care, the PACE program educates trainees in all health care disciplines, conducts research, and disseminates information about important procedures and outcomes. Undergraduate and graduate trainees from 11 health care disciplines rotate through the PACE program to learn an integrated approach to managed ambulatory care delivery. All trainees are involved in a problem-based approach to learning that emphasizes shared training experiences among health care disciplines. This paper describes the transitional phases of the PACE program (strategic planning, reorganization, and quality improvement) that are relevant for other institutions that are shifting to training programs emphasizing primary and ambulatory care.
