Does physician education on depression management improve treatment in primary care?

OBJECTIVE: To assess the effect of physician training on management of depression. DESIGN: Primary care physicians were randomly assigned to a depression management intervention that included an educational program. A before-and-after design evaluated physician practices for patients not enrolled in the intervention trial. SETTING: One hundred nine primary care physicians in 2 health maintenance organizations located in the Midwest and Northwest regions of the United States. PATIENTS/PARTICIPANTS: Computerized pharmacy and visit data from a group of 124,893 patients who received visits or prescriptions from intervention and usual care physicians. INTERVENTIONS: Primary care physicians received education on diagnosis and optimal management of depression over a 3-month training period. Methods of education included small group interactive discussions, expert demonstrations, role-play, and academic detailing of pharmacotherapy, criteria for urgent psychiatric referrals, and case reviews with psychiatric consultants. MEASUREMENTS AND MAIN RESULTS: Pharmacy and visit data provided indicators of physician management of depression: rate of newly diagnosed depression, new prescription of antidepressant medication, and duration of pharmacotherapy. One year after the training period, intervention and usual care physicians did not differ significantly in the rate of new depression diagnosis (P =.95) or new prescription of antidepressant medicines (P =.10). Meanwhile, patients of intervention physicians did not differ from patients of usual care physicians in adequacy of pharmacotherapy (P =.53) as measured by 12 weeks of continuous antidepressant treatment. CONCLUSIONS: After education on optimal management of depression, intervention physicians did not differ from their usual care colleagues in depression diagnosis or pharmacotherapy.

How managed care can be ethical.

The growth of managed care in the United States has been paralleled by a rising tide of anti-managed care sentiment. The "managed care problem" is understood generally as the need to protect individuals against large companies that care more about their bottom line than about people. The premise of the BEST (Best Ethical Strategies for Managed Care) project is that the "managed care problem" is best understood as an ethical problem--a conflict of values that arises as the country changes from a patient-centered to a population-centered approach to health care. The BEST project team worked with nine managed care organizations to identify their most intractable problems. The team redefined these problems in terms of ethical dilemmas, then studied each organization in search of innovative, exemplary approaches. These exemplary approaches are being shared publicly with the aim that they be adapted and adopted by other organizations facing similar difficulties and by regulators and legislators hoping to improve the health care system.

Patient attitudes toward physician financial incentives.

BACKGROUND: Despite concern about the impact of financial incentives on physician behavior, little is known about patients' attitudes toward these incentives. OBJECTIVES: To assess patient attitudes toward physician compensation models and to explore patient characteristics associated with these attitudes. METHODS: We mailed a survey to 2000 adult patients in a large New England health maintenance organization. We asked about their trust in their primary care physician; discomfort with compensation models of salary with withhold (salary), fee-for-service with withhold, and group capitation (capitation). RESULTS: One thousand one hundred twenty-five (56%) of the 2000 patients who responded expressed varying levels of discomfort with the proposed compensation models: 16% for salary, 25% for fee-for-service with withhold, and 53% for capitation (P<.001). Patients who knew their primary care physician was paid through capitation did not report less trust in their primary care physician but still frequently expressed discomfort (46%) with capitation. Among all respondents, those who were younger, white, had better health, had a higher income, were more educated, and who lacked a very trusting relationship with a primary care physician were more likely to report discomfort with both capitation and fee-for-service with withhold. In multivariable analyses, discomfort with capitation was more common among white patients (odds ratio, 2.6; 95% confidence interval, 1.6-4.2), patients with incomes exceeding $20 000 (odds ratio, 3.7; 95% confidence interval, 2.3-6.1), and college-educated patients (odds ratio, 2.0; 95% confidence interval, 1.4-2.7). CONCLUSIONS: Most patients were uncomfortable with 1 or more of the 3 common methods used to pay physicians. Discomfort was highest with capitation and was more likely among wealthier, well-educated, white patients. With capitation increasing nationally, patients' concerns should be considered in the design of compensation agreements.

Critical pathways intervention to reduce length of hospital stay.

PURPOSE: Despite their popularity, critical pathways have been evaluated in only a few controlled studies. We evaluated the effectiveness of critical pathways in reducing length of hospital stay. SUBJECTS AND METHODS: We compared postoperative lengths of stay of patients who underwent coronary artery bypass graft (CABG) surgery, total knee replacement, colectomy, thoracic surgery, or hysterectomy before and after pathway implementation at a university hospital. For three procedures, changes in lengths of stay at neighboring hospitals without pathway programs were assessed for comparison. RESULTS: A total of 6,796 patients underwent one of the procedures during the study. The percentage of eligible patients managed on a critical pathway ranged from 94% for hysterectomy to 26% for colectomy. For most procedures, the postoperative length of stay was decreasing during the baseline period. After pathway implementation, the length of stay decreased 21% for total knee replacement, 9% for CABG surgery, 7% for thoracic surgery, 5% for hysterectomy, and 3% for colectomy (all P < 0.01). However, similar decreases were seen in the neighboring hospitals that did not have critical pathways or other specific efficiency initiatives. CONCLUSIONS: Critical pathways were associated with a rapid reduction in postoperative length of stay after all five study procedures. Secular trends at nearby hospitals, however, produced comparable reductions for the three procedures available for comparison. These findings raise questions about the effectiveness of critical pathways in a competitive environment.

Cost-effectiveness of systematic depression treatment for high utilizers of general medical care.

BACKGROUND: Expanding access to high-quality depression treatment will depend on the balance of incremental benefits and costs. We examine the incremental cost-effectiveness of an organized depression management program for high utilizers of medical care. METHODS: Computerized records at 3 health maintenance organizations were used to identify adult patients with outpatient medical visit rates above the 85th percentile for 2 consecutive years. A 2-step screening process identified patients with current depressive disorders, who were not in active treatment. Eligible patients were randomly assigned to continued usual care (n = 189) or to an organized depression management program (n = 218). The program included patient education, antidepressant pharmacotherapy initiated in primary care (when appropriate), systematic telephone monitoring of adherence and outcomes, and psychiatric consultation as needed. Clinical outcomes (assessed using the Hamilton Depression Rating Scale on 4 occasions throughout 12 months) were converted to measures of "depression-free days." Health services utilization and costs were estimated using health plan-standardized claims. RESULTS: The intervention program led to an adjusted increase of 47.7 depression-free days throughout 12 months (95% confidence interval [CI], 28.2-67.8 days). Estimated cost increases were $1008 per year (95% CI, $534-$1383) for outpatient health services, $1974 per year for total health services costs (95% CI, $848-$3171), and $2475 for health services plus time-in-treatment costs (95% CI, $880-$4138). Including total health services and time-in-treatment costs, estimated incremental cost per depression-free day was $51.84 (95% CI, $17.37-$108.47). CONCLUSIONS: Among high utilizers of medical care, systematic identification and treatment of depression produce significant and sustained improvements in clinical outcomes as well as significant increases in health services costs.

Leaving gatekeeping behind--effects of opening access to specialists for adults in a health maintenance organization.

BACKGROUND: Gatekeeping refers to the prior approval of referrals to specialists by a primary care physician. Although many health plans view gatekeeping as an essential tool for controlling costs and coordinating care, many patients and physicians object to it. METHODS: On April 1, 1998, Harvard Vanguard Medical Associates, a large, multispecialty, capitated group practice previously known as Harvard Community Health Plan, eliminated a gatekeeping system that had been in place for over 25 years. We determined the effects of opening access to specialists on visits to primary care physicians and specialists by adults. In randomly selected cohorts of 10,000 members each, we analyzed visits during 6-month periods for the 3 years before and 18 months after gatekeeping was eliminated. RESULTS: Adults visited a primary care physician an average of 1.21 times and 1.19 times per six-month period before and after the elimination of gatekeeping, respectively (P=0.05); the average number of visits to a specialist was 0.78 per six-month period both before and after its elimination (P=0.35). There was little change in the percentage of visits to specialists included in the analysis as a proportion of all visits (39.1 percent before the elimination of gatekeeping and 39.5 percent afterward). The percentage of first visits to specialists as a proportion of all visits to specialists included in the analysis increased from 24.7 to 28.2 percent (P<0.001). There were small increases in the numbers of visits to orthopedists and physical or occupational therapists. The proportion of visits to specialists for low back pain that were new consultations increased from 26.6 to 32.9 percent (P=0.01). CONCLUSIONS: In a capitated, multispecialty group practice, we found little evidence of substantial changes in the use of specialty services by adults in the first 18 months after the elimination of gatekeeping.

The impact of an inpatient physician program on quality, utilization, and satisfaction.

OBJECTIVE: To evaluate an inpatient physician system initiated in June 1996 for all patients of a health maintenance organization admitted to the general medicine service of an urban teaching hospital. In the new program, attending physician duties were transferred from the patient's own general internist to another internist serving on a hospital-based rotation. STUDY DESIGN: Cohort with historical controls. PARTICIPANTS AND METHODS: We compared the following measures before and after the new inpatient physician program began: (1) hospital length of stay and total charges, (2) outcomes related to quality of care, (3) primary care physician satisfaction, and (4) housestaff satisfaction. Differences before and after initiation of the inpatient physician program were evaluated using multivariate analyses to adjust for patient differences and secular trends. RESULTS: There were 2265 patients discharged from the general medical service in the year following implementation of the inpatient physician program. Postintervention average length of stay decreased from 3.5 to 3.0 days (P < .001). In multivariate analyses, average length of stay was reduced by 0.3 days (P = .008), and total hospital charges were reduced an average of $426 per admission (P = .001). In-hospital mortality rates, percentage of patients discharged home directly, and 30-day readmission rates did not change significantly in the postintervention period. Satisfaction among primary care physicians was high, with 90% of those answering a survey responding that they would recommend a similar program to other primary care groups. Medical housestaff satisfaction with their educational experience also increased. CONCLUSIONS: Implementation of an inpatient physician program at this institution significantly decreased resource utilization while maintaining or improving quality of care. Satisfaction with the program was high among primary care internists and housestaff.

Patients' trust in physicians: many theories, few measures, and little data.

Trust is one of the central features of patient-physician relationships. Rapid changes in the health care system are feared by many to be threatening patients' trust in their physicians. Yet, despite its acknowledged importance and potential fragility, rigorous efforts to conceptualize and measure patient trust have been relatively few. This article presents a synopsis of theories about patient trust and the evolution of methods to measure it. Clinicians, educators, and researchers interested in this area may find this information useful in practice and teaching. The gaps identified in our knowledge about trust can help target new efforts to strengthen the methodological basis of work to understand this vital element of medical relationships.

Caring and cost: the challenge for physician advocacy.

How should physicians respond to the growing tension between care and cost? One option is to reinforce the ideal of doing everything to further the best interests of the individual patient. Others, however, have argued that because health care resources are shared and limited, physicians should consciously participate in rationing by saying "no" to patients' requests for some marginally beneficial services. But even physicians who endorse the idea of rationing wonder whether patient-physician relationships could ever survive a frank admission of rationing at the bedside. This article explores the idea that caring about costs can be brought to the bedside in a way that will sustain trust among patients and the public. By illustrating a hypothetical case and the ensuing conversation between a physician and her patient, a mode of "proportional" patient advocacy is presented in which physicians can remain forceful agents for patient good while acting within a framework that admits to the boundaries of responsible budgets for health care needs.

Randomized trial of a depression management program in high utilizers of medical care.

BACKGROUND: High utilizers of nonpsychiatric health care services have disproportionally high rates of undiagnosed or undertreated depression. OBJECTIVE: To determine the impact of offering a systematic primary care-based depression treatment program to depressed "high utilizers" not in active treatment. DESIGN: Randomized clinical trial. SETTING: One hundred sixty-three primary care practices in 3 health maintenance organizations located in different geographic regions of the United States. PATIENTS: A group of 1465 health maintenance organization members were identified as depressed high utilizers using a 2-stage telephone screening process. Eligibility criteria were met by 410 patients and 407 agreed to enroll: 218 in the depression management program (DMP) practices and 189 in the usual care (UC) group. INTERVENTION: The DMP included patient education materials, physician education programs, telephone-based treatment coordination, and antidepressant pharmacotherapy initiated and managed by patients' primary care physicians. MAIN OUTCOME MEASURES: Depression severity was measured using the Hamilton Depression Rating Scale (Ham-D) and functional status using the Medical Outcomes Study 20-item short form (SF-20) subscales. Outpatient visit and hospitalization rates were measured using the health plan's encounter data. RESULTS: Based on an intent-to-treat analysis, at least 3 antidepressant prescriptions were filled in the first 6 months by 151 (69.3%) of 218 of DMP patients vs 35 (18.5%) of 189 in UC (P < .001). Improvements in Ham-D scores were significantly greater in the intervention group at 6 weeks (P = .04), 3 months (P = .02), 6 months (P < .001), and 12 months (P < .001). At 12 months, DMP intervention patients were more improved than UC patients on the mental health, social functioning, and general health perceptions scales of the SF-20 (P < .05 for all). CONCLUSION: In depressed high utilizers not already in active treatment, a systematic primary care-based treatment program can substantially increase adequate antidepressant treatment, decrease depression severity, and improve general health status compared with usual care.

Direct admission to an extended-care facility from the emergency department.

BACKGROUND: Many patients are admitted to acute-care hospitals when their medical needs might be more appropriately met in an extended-care facility (ECF). OBJECTIVE: To describe a cohort of patients who were admitted from an emergency department to an ECF. DESIGN: Observational cohort study. PARTICIPANTS: 121 enrollees of Harvard Vanguard Medical Associates who were admitted directly from an emergency department to an ECF between October 1, 1994, and December 31, 1997. OUTCOME MEASURES: Mean length of stay, charges per patient, and discharge disposition (discharged to home, discharged to a long-term-care facility, died, or transferred to an acute-care hospital within 30 days of ECF admission). RESULTS: Patients admitted directly to an ECF were generally frail and elderly (median age, 75 years). Mean length of stay in the ECF was 11 days; the mean per-patient charge was $3290. Three quarters of patients were discharged from the ECF to their homes. Six percent (seven patients) were transferred from the ECF to an acute-care hospital within 30 days of ECF admission. None of these transfers clearly suggested that the initial decision to directly admit a patient to the ECF was inappropriate. Most patients were satisfied with direct ECF admission: Of the surviving, cognitively intact patients admitted to an ECF in 1997, 71% stated that they would choose direct admission to an ECF over admission to an acute-care hospital if they were "in a similar situation in the future." CONCLUSIONS: For selected patients, direct admission to an ECF seems to be feasible, safe, and acceptable. A randomized, clinical trial is needed to fully assess the safety and cost implications of direct ECF admission.

Depression among high utilizers of medical care.

OBJECTIVE: To determine the prevalence of unrecognized or unsuccessfully treated depression among high utilizers of medical care, and to describe the relation between depression, medical comorbidities, and resource utilization. DESIGN: Survey. SETTING: Three HMOs located in different geographic regions of the United States. PATIENTS: A total of 12,773 HMO members were identified as high utilizers. Eligibility criteria for depression screening were met by 10,461 patients. MEASUREMENTS AND MAIN RESULTS: Depression status was assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders. Fourth Edition. Depression screening was completed in 7,203 patients who were high utilizers of medical care, of whom 1,465 (20.3%) screened positive for current major depression or major depression in partial remission. Among depressed patients, 621 (42.4%) had had a visit with a mental health specialist or a diagnosis of depression or both within the previous 2 years. The prevalence of well-defined medical conditions was the same in patients with and patients without evidence of depression (41.5% vs 41.5%, p = .87). However, high-utilizing patients who had not made a visit for a nonspecific complaint during the previous 2 years were at significantly lower risk of depression (13.1% vs 22.4%, p < .001). Patients with current depression or depression in partial remission had significantly higher numbers of annual office visits and hospital days per 1,000 than patients without depression. CONCLUSIONS: Although there was evidence that mental health problems had previously been recognized in many of the patients, a large percentage of high utilizers still suffered from active depression that either went unrecognized or was not being treated successfully. Patients who had not made visits for nonspecific complaints were at significantly lower risk of depression. Depression among high utilizers was associated with higher resource utilization.

Deep venous thrombosis: complete lower extremity venous US evaluation in patients without known risk factors--outcome study.

PURPOSE: To determine the diagnostic value of venous ultrasonography (US) that includes examination of calf veins in symptomatic patients suspected of having deep venous thrombosis (DVT) of the lower extremities. MATERIALS AND METHODS: A retrospective cohort study of the prevalence of DVT included 977 consecutive patients with possible DVT but without known risk factors for DVT. Color flow and compression US were performed. The outcome was the frequency of overlooked, clinically important DVT after negative initial results from bilateral venous US of above- and below-the-knee veins. Patient records (904 patients), mailed questionnaires (61 patients), and telephone contacts (12 patients) were used to establish a diagnosis of clinically relevant DVT. RESULTS: The prevalence of DVT was 15% (142 of 977), with DVT in 15% (21 of 142) restricted to the below-the-knee veins. Follow-up (median, 34 months) in 835 patients with negative US findings showed one occurrence of venous thrombosis (superficial thrombophlebitis) during the first 3 months of follow-up. Three other cases of venous thrombosis occurred at 17, 18, and 48 months of follow-up but were believed not to be linked to the initial complaint. The incidence of overlooked DVT was 0% (95% CI, 0.0%, 0.4%). CONCLUSION: In patients without risk factors for DVT, a negative venous US study can help exclude the presence of clinically important DVT if the examination includes careful evaluation of the calf veins.

An outpatient program to treat deep venous thrombosis with low-molecular-weight heparin.

CONTEXT: Although recent trials have demonstrated the safety and efficacy of low-molecular-weight (LMW) heparin, clinicians may need help incorporating this drug into routine practice. OBJECTIVE: To describe the development, implementation, and early results of an outpatient LMW heparin program for acute deep venous thrombosis (DVT). DESIGN: Before-after study. SETTING: Eight health centers of Harvard Vanguard Medical Associates, a multispecialty group practice in Boston. PATIENTS: Patients with confirmed acute, lower-extremity DVT before (40 patients given a diagnosis from January to August 1996) and after (67 patients given a diagnosis from September 1996 to April 1997) implementation of the LMW heparin program. INTERVENTION: A centrally coordinated outpatient LMW heparin program. DATA SOURCES: Hospital and HMO financial databases; electronic patient medical records. OUTCOME MEASURES: Costs of care for 2-week episodes and short-term clinical outcomes. RESULTS: The proportion of patients with DVT treated in the hospital decreased from 90% to 46% after the introduction of the LMW heparin program. The mean cost of treatment for all patients with DVT decreased from $5465 to $3719 per patient. For the subset of patients actually treated in the outpatient program, the average cost was $1402 per patient. There were no deaths, no clinically recognized pulmonary emboli, and no cases of significant bleeding among patients treated in the program, although 3 patients were subsequently hospitalized for worsening leg pain. CONCLUSIONS: The cost of caring for patients with DVT decreased after introduction of the outpatient LMW heparin program. Given explicit selection criteria, short-term clinical outcomes after outpatient management have been excellent. This program may serve as a model for physicians and health plans interested in establishing a program for treating acute DVT in the outpatient setting.

Communication problems for patients hospitalized with chest pain.

In many settings, primary care physicians have begun to delegate inpatient care to hospitalists, but the impact of this change on patients' hospital experience is unknown. To determine the effect on physician-patient communication of having the regular outpatient physician (continuity physician) continue involvement in hospital care, we surveyed 1,059 consecutive patients hospitalized with chest pain. Patients whose continuity physicians remained involved in their hospital care were less likely to report communication problems regarding tests (20% vs 31%, p =.03), activity after discharge (42% vs 51%, p =.02), and health habits (31% vs 38%, p =. 07). In a setting without a designated hospitalist system, communication problems were less frequent among patients whose continuity physicians were involved in their hospital care. New models of inpatient care delivery can maintain patient satisfaction but to do so must focus attention on improving physician-patient communication.

Informal consultations provided to general internists by the gastroenterology department of an HMO.

OBJECTIVE: To study the process, outcomes, and time spent on informal consultations provided by gastroenterologists to the primary care general internists of an HMO. DESIGN: Observational study. SETTING: A large, urban staff-model HMO. PATIENTS/PARTICIPANTS: Seven gastroenterologists constituting the total workforce of the gastroenterology department of the HMO. MEASUREMENTS AND MAIN RESULTS: Data on 91 informal consultations were obtained, of which 55 (60%) involved the acute management of a patient with new symptoms or test results, and 36 (40%) were for questions related to nonacute diagnostic test selection or medical therapy. Questions regarding patients previously unknown to the gastroenterology department accounted for 74 (81%) of the consultations. Formal referral was recommended in only 16 (22%) of these cases. As judged by the time data gathered on the 91 consultations, the gastroenterologists spent approximately 7.2 hours per week to provide informal consultation for the entire HMO. CONCLUSIONS: Gastroenterologists spend a significant amount of time providing informal consultation to their general internist colleagues in this HMO. The role informal consultation plays in the workload of physicians and in the clinical care of populations is an important question for health care system design, policy, and research.
