Reducing obesity prejudice in medical education.

BACKGROUND: Healthcare worker attitudes toward obese individuals facilitate discrimination and contribute to poor health outcomes. Previous studies have demonstrated medical student bias toward obese individuals, but few have examined effects of the educational environment on these prejudicial beliefs. We sought to determine whether an innovative educational intervention (reading a play about obesity) could diminish obesity prejudice relative to a standard medical lecture. METHODS: We conducted a randomized, controlled trial enrolling medical students (n = 129) from three universities. Students were assigned to play-reading or a standard lecture. Explicit attitudes and implicit bias toward obese individuals were assessed prior to intervention and after four months. RESULTS: At baseline, students demonstrated moderate explicit and implicit bias toward obese people despite high scores on empathy. Students randomized to the play-reading group had significantly decreased explicit fat bias (P = 0.01) at follow-up, while students in the lecture group showed increased endorsement of a prescriptive model of care at the expense of a patient-centered approach (P = 0.03). There was a significant increase in empathy for those in both the theater (P = 0.007) and lecture group (P = 0.02). The intervention had no significant effect on implicit bias or regard for obesity as a civil rights issue. DISCUSSION: Dramatic reading may be superior to traditional medical lectures for showcasing patient rights and preferences. The present study demonstrates for the first time that play-reading diminishes conscious obesity bias. Further research should determine whether nontraditional methods of instruction promote improved understanding of and care for obese patients.

Individualized patient education and coaching to improve pain control among cancer outpatients.

PURPOSE: An estimated 42% of cancer patients suffer from poorly controlled pain, in part because of patient-related barriers to pain control. The objective of this study was to evaluate the effect of an individualized education and coaching intervention on pain outcomes and pain-related knowledge among outpatients with cancer-related pain. PATIENTS AND METHODS: English-speaking cancer patients (18 to 75 years old) with moderate pain over the past 2 weeks were randomly assigned to the experimental (n = 34) or control group (n = 33). Experimental patients received a 20-minute individualized education and coaching session to increase knowledge of pain self-management, to redress personal misconceptions about pain treatment, and to rehearse an individually scripted patient-physician dialog about pain control. The control group received standardized instruction on controlling pain. Data on average pain, functional impairment as a result of pain, pain frequency, and pain-related knowledge were collected at enrollment and 2-week follow-up. RESULTS: At baseline, there were no significant differences between experimental and control groups in terms of average pain, functional impairment as a result of pain, pain frequency, or pain-related knowledge. At follow-up, average pain severity improved significantly more among experimental group patients than among control patients (P =.014). The intervention had no statistically significant impact on functional impairment as a result of pain, pain frequency, or pain-related knowledge. CONCLUSION: Compared with provision of standard educational materials and counseling, a brief individualized education and coaching intervention for outpatients with cancer-related pain was associated with improvement in average pain levels. Larger studies are needed to validate these effects and elucidate their mechanisms.

Underuse of coronary revascularization procedures: application of a clinical method.

OBJECTIVES: Our main objective was to apply a new method to determine whether coronary revascularization procedures are underused, especially among African-Americans and uninsured patients. BACKGROUND: Although overuse of revascularization procedures has been studied, underuse as defined clinically has not been examined before. METHODS: The study was conducted at four public and two academically affiliated private hospitals in Los Angeles; 671 patients who underwent coronary angiography between June 1, 1990 and September 30, 1991 and met explicit clinical criteria for coronary revascularization were included. The main outcome measure was the proportion of patients undergoing an indicated procedure within 12 months (ascertained by medical record review and confirmed with a telephone survey). Adjusted relative odds of undergoing an indicated procedure for African-Americans and patients in public hospitals compared with whites and patients in private hospitals were calculated. RESULTS: Overall, 75% of patients underwent a revascularization procedure. Of 424 patients requiring bypass surgery, 107 angioplasty and 140 either bypass surgery or angioplasty, 59%, 66% and 75% underwent the procedure, respectively. African-Americans were less likely than whites to undergo operation (adjusted odds ratio [OR] 0.49, p < 0.05) and angioplasty (adjusted OR 0.20, p < 0.05). Patients in public hospitals were less likely than those in private hospitals to undergo angioplasty (adjusted OR 0.10, p < 0.005). CONCLUSIONS: Underuse of coronary revascularization procedures is measurable and occurs to a significant degree even among insured patients attending private hospitals. Underuse is especially pronounced among African-Americans and patients attending public hospitals. Future cost-containment efforts must incorporate safeguards against underuse of necessary care.

Effect of physician specialty on use of necessary coronary angiography.

OBJECTIVES: This study sought to determine whether having a cardiologist as a regular source of care influences likelihood of undergoing necessary coronary angiography. BACKGROUND: An important element of the current health policy debate is the respective roles of primary care and specialist physicians. However, there are few data on interspecialty differences in quality of care for patients with ischemic heart disease. METHODS: We contacted 243 patients by telephone (response rate 72%) who had positive (or very positive) exercise stress test results and met additional clinical criteria for necessary coronary angiography. Study patients were randomly sampled from those undergoing exercise stress testing at one university and three public hospitals in Los Angeles between January 1, 1990 and June 30, 1991. Patients were asked whether they had a regular source of care during the time after their exercise stress test and, if so, whether that provider was a cardiologist or cardiology clinic. RESULTS: Among survey responders, 47% underwent necessary coronary angiography within 3 months of exercise testing and 61% within 12 months. After adjustment for sociodemographics and clinical presentation, patients with a cardiologist as a regular source of care were more likely than all other patients to have undergone necessary angiography within 3 months (52% vs. 38%, p = 0.05) and within 12 months (74% vs. 44%, p = 0.0001) of the exercise test. At 3 months, there was a trend toward a more pronounced effect of ongoing cardiologic care within the public hospitals compared with the private hospital (p = 0.09 for interaction between hospital types). CONCLUSIONS: Patients with a cardiologist as a regular source of care were more likely than all other patients to undergo clinically necessary coronary angiography within both 3 and 12 months of exercise stress testing.

Differences in clinical decision making between internists and cardiologists.

BACKGROUND: Whether cardiologists or internists use discretionary tests differently for noncritical cardiological presentation is unclear. OBJECTIVE: To explore differences in decision making for 3 common scenarios. METHODS: We asked 318 cardiologists and 598 internists to manage scenario patients presenting with (1) uncomplicated syncope, (2) nonanginal chest pain, and (3) nonspecific electrocardiographic changes. Participants also estimated baseline clinical risk for each scenario and answered questions on uncertainty, malpractice concerns, and cost consciousness. We used chi 2 analysis, analysis of variance, and t tests to compare management choice and test ordering. Response rate was 50%. RESULTS: Initial management choices (ie, admit or discharge, allow or delay surgery) were similar but subsequent testing differed substantially. For a 50-year-old woman with uncomplicated syncope, cardiologists more often recommended cardiological tests such as exercise treadmill tests (37% vs 18%, 95% confidence interval [CI] for difference: 10%-28%) and signal-averaged electrocardiograms (13% vs 4%, 95% CI for difference: 3%-15%) but less often requested neurological tests (29% vs 37%, 95% CI for difference: -17% to 1%). For a 42-year-old man with nonanginal chest pain, cardiologists more frequently ordered exercise tests (70% vs 51%, 95% CI for difference: 10%-28%). For a 53-year-old woman with nonspecific electrocardiographic changes, equal proportions of cardiologists and internists ordered exercise tests (56%) but cardiologists recommended thallium studies more often (73% vs 47%, 95% CI for difference: 10%-36%). For all scenarios, average charges for diagnostic evaluations by cardiologists and internists were similar. CONCLUSIONS: In 3 noncritical cardiology scenarios, discretionary test use by cardiologists and internists differed substantially, although this was not reflected in dollar resources. Internists tended toward a broader diagnostic evaluation while cardiologists tended to focus on cardiological tests. The potential effect on clinical outcomes is unknown.

Unsaid but not forgotten: patients' unvoiced desires in office visits.

OBJECTIVES: To examine patient, physician, and health care system characteristics associated with unvoiced desires for action, as well as the consequences of these unspoken requests. PATIENTS AND METHODS: Patient surveys were administered before, immediately after, and 2 weeks after outpatient visits in the practices of 45 family practice, internal medicine, and cardiology physicians working in a multispecialty group practice or group model health maintenance organization. Data were collected at the index visit from 909 patients, of whom 97.6% were surveyed 2 weeks after the outpatient visit. Before the visit, patients rated their trust in the physician, health concerns, and health status. After the visit, patients reported on various types of unexpressed desires and rated their visit satisfaction. At follow-up, patients rated their satisfaction, health concerns, and health status, and also described their postvisit health care use. Evaluations of the visit were also obtained from physicians. RESULTS: Approximately 9% of the patients had 1 or more unvoiced desire(s). Desires for referrals (16.5% of desiring patients) and physical therapy (8.2%) were least likely to be communicated. Patients with unexpressed desires tended to be young, undereducated, and unmarried and were less likely to trust their physician. Patients with unvoiced desires evaluated the physician and visit less positively; these encounters were evaluated by physicians as requiring more effort. Holding an unvoiced desire was associated with less symptom improvement, but did not affect postvisit health care use. CONCLUSIONS: Patients' unvoiced needs affect patients' and physicians' visit evaluations and patients' subjective perceptions of improvement. Implications of these findings for clinical practice are examined.

Recall of recommendations and adherence to advice among patients with chronic medical conditions.

BACKGROUND: Patient adherence to treatment regimens may be a critical mediator between physician recommendations and patient outcomes, but levels of adherence have not been compared across disease groups, and patient self-reports have not been well validated. METHODS: To determine recall of and adherence to physicians' recommendations among patients with chronic medical conditions and to measure the correspondence between self-reported adherence and disease activity, we analyzed data from the Medical Outcomes Study. A total of 1751 patients with diabetes mellitus, hypertension, and heart disease were identified among 20,223 patients visiting family physicians, general internists, cardiologists, and endocrinologists in 1986. Main outcome measures included recall of 15 disease-specific recommendations, self-reported general and specific adherence, and correlations between adherence and clinical measures of disease activity and control. RESULTS: Among patients in all three disease groups, the proportion recalling recommendations to take prescribed medications (> or = 90%) exceeded the fraction recalling recommendations to follow a restricted diet, exercise regularly, and perform various self-care activities (22% to 84%). Adherence to recalled recommendations was similar across conditions but varied markedly according to the nature of the recommendations; for example, 91% of diabetics took prescribed medications but 69% followed a diabetics diet and 19% engaged in regular exercise. Adherence to recommendations was correlated with reduced serum glucose (r = -.33) and glycohemoglobin (r = -.25) levels among insulin-dependent diabetics and with reduced diastolic blood pressure among patients with hypertension (r = -.15). CONCLUSIONS: The majority of chronically ill patients failed to recall elements of potentially important medical advice and did not always adhere to advice that was recalled. Self-reported adherence was correlated with clinical measures of disease activity and control. Additional research is needed not only to improve adherence to medical advice in patients with chronic illnesses but also to determine which life-style changes are truly beneficial for these patients.

Postdischarge geriatric assessment of hospitalized frail elderly patients.

BACKGROUND: The diffusion of comprehensive geriatric assessment services has been rather limited in North America partly because of reimbursement and organizational constraints. OBJECTIVE: To evaluate the impact of a comprehensive geriatric assessment intervention for frail older patients that is started before hospital discharge and is continued at home. METHODS: Patients older than 65 years were selected who had either unstable medical problems, recent functional limitations, or potentially reversible geriatric clinical problems. Patients (n = 354) were randomly assigned to either the intervention group or a control group. Information on survival, readmissions, nursing home placement, medication use, and health status was collected at 30 and 60 days after hospital discharge. RESULTS: No differences were observed between the two treatment groups in survival, hospital readmission, or nursing home placement by 60 days. After adjustment for baseline characteristics, no significant differences were observed between the two groups on measures of physical functioning, social functioning, role limitations, health perceptions, pain, mental health, energy and/or fatigue, health change, or overall well-being. CONCLUSIONS: Although efficacy has been demonstrated for some forms of comprehensive geriatric assessment, the types of services that are easier to establish (inpatient consultation services and ambulatory assessment) have not been shown to improve outcomes. Our results indicate that outcomes are unaffected by a limited form of comprehensive geriatric assessment begun in the hospital and completed at home. Further efforts are needed to develop and to evaluate realistic approaches to comprehensive geriatric assessment.

Geriatric home assessment after hospital discharge.

OBJECTIVES: To evaluate the feasibility of an intervention involving post-discharge geriatric home assessment and follow-up and to describe the spectrum of significant clinical problems identified during the home assessment. DESIGN: Prospective observational study nested within a randomized controlled trial. SETTING: Inpatient service of a large academic medical center in Southern California. PATIENTS: There were 152 adults aged 65 or greater who had one or more specific risk factors for functional decline or increased mortality, who were awaiting discharge from the hospital, and who were assigned to the intervention arm of a randomized controlled trial of post-discharge comprehensive geriatric home assessment. MAIN RESULTS: During the home assessment, the gerontologic nurse practitioner (GNP) identified new or worsening problems in 150 patients (99%); 61 problems (eg, serum sodium 125 mg/dL; severe orthostatic hypotension) were considered by a reviewing physician to require urgent medical attention. Older age, non-white race, and new incontinence were associated independently with a greater number of findings (P < 0.05). Based on the findings, an interdisciplinary team made an average of 3.4 recommendations per patient; only two of 111 requests for written approval of recommendations were rejected. CONCLUSIONS: Post-discharge visitation by a GNP to patients at high risk is capable of detecting a high yield of important and potentially reversible clinical problems. This multidisciplinary approach is acceptable to physicians. Research is needed to identify additional links between short hospital stays, impairment or instability at discharge, and adverse outcomes.

Parent expectations for antibiotics, physician-parent communication, and satisfaction.

OBJECTIVES: To explore how parents communicate their preferences for antibiotics to their child's physician and to examine whether physicians can communicate why antibiotics are not being prescribed in a way that maintains satisfaction with the visit. DESIGN: Previsit survey of parents, audiotaping of the study encounters, and a postvisit survey of parents and physicians. SETTING: Two private pediatric practices. PARTICIPANTS: Ten physicians (response rate = 77%) and a consecutive sample of 295 eligible parents (response rate = 86%) who attended acute care visits for their children between October 1996 and March 1997. MAIN OUTCOME MEASURES: Physician-perceived pressure to prescribe antibiotics and parental visit-specific satisfaction. RESULTS: Fifty percent of parents expressed a previsit expectation for antibiotics. Among these parents, only 1% made a direct verbal request for them. Even when no direct requests for antibiotics were made, physicians still perceived an expectation for antibiotics 34% of the time. Among parents who did not receive expected antibiotics, those offered a contingency plan from the physician (i.e., the possibility of receiving antibiotics in the future if their child did not get better) had a higher mean satisfaction score than parents not receiving a contingency plan (76 vs. 58.9; P<.05). CONCLUSION: Physicians should consider providing a contingency plan to parents who expect antibiotics for their children when there is no clinical indication. Further study is needed to determine how parents indirectly communicate their desire for antibiotics and what additional communication techniques physicians can use to resist the overprescribing of antibiotics.

Vaginal birth after cesarean in California.

OBJECTIVE: To estimate rates at which women were offered and consented to trial of labor in California hospitals with high and low risk-adjusted cesarean delivery rates. METHODS: From 267 nonfederal acute-care hospitals in California that performed more than 678 deliveries in 1992-1993, 51 hospitals were selected in a stratified sample. Hospitals in the sample were categorized as having high, medium, and low risk-adjusted cesarean rates using a logistic regression model based on data from the California Patient Discharge Data System. We reviewed medical records of women with previous cesareans for evidence of counseling regarding trial of labor, other clinical variables, and method of delivery. Differences in proportions between the three groups of hospitals were compared. RESULTS: According to records of 369 women with previous cesareans, after excluding contraindications, 312 were potentially eligible for trial of labor. Hospitals with low risk-adjusted cesarean rates documented counseling women for trial of labor in over 99% of records reviewed, compared with 85% and 79%, respectively, of hospitals with intermediate and high rates (P <.001). Rates of completed vaginal births after cesarean were 71% in hospitals with low risk-adjusted cesarean rates, compared with 39% and 31% in hospitals with intermediate and high rates (P <.05). CONCLUSIONS: California hospitals with high cesarean rates in 1992-1993 had markedly higher rates of repeat elective cesarean delivery without evidence of counseling regarding trial of labor. Informed patient choice is a critical element of the decision for trial of labor or elective repeat cesarean, and lack of documented counseling is cause for concern.

Direct-to-consumer prescription drug advertising: trends, impact, and implications.

We provide an overview of what is known about the impact of direct-to-consumer (DTC) advertising of prescription drugs. Specifically, we explore the historical trends that led to the industry's increasing use of this form of promotion. Then, using the published literature to date, we review the impact of DTC advertising on the consumer, the medical profession, and the health care system. We conclude by offering policy suggestions for how the pharmaceutical industry can promote its products more responsibly, how the Food and Drug Administration (FDA) can regulate DTC advertising more effectively, and how the medical and public health communities can educate the public about drug therapies more constructively.

Physicians' characteristics influence patients' adherence to medical treatment: results from the Medical Outcomes Study.

The influence of physicians' attributes and practice style on patients' adherence to treatment was examined in a 2-year longitudinal study of 186 physicians and their diabetes, hypertension, and heart disease patients. A physician-level analysis was conducted, controlling for baseline patient adherence rates and for patient characteristics predictive of adherence in previous analyses. General adherence and adherence to medication, exercise, and diet recommendations were examined. Baseline adherence rates were associated with adherence rates 2 years later. Other predictors were physician job satisfaction (general adherence), number of patients seen per week (medication), scheduling a follow-up appointment (medication), tendency to answer patients' questions (exercise), number of tests ordered (diet), seriousness of illness (diet), physician specialty (medication, diet), and patient health distress (medication, exercise).

Bedside charting of pain levels in hospitalized patients with cancer: a randomized controlled trial.

Despite advances in the technology of cancer pain assessment and control, cancer pain often remains undertreated even in hospital settings. To determine whether a graphical display of cancer patients' pain levels might improve their treatment, the investigators conducted a randomized controlled trial. Patients assigned to the intervention group (N = 40) had periodic pain assessments by study staff, who graphically recorded their reported pain-intensity levels on bedside wall charts. Control group patients (N = 38) had periodic pain assessments by study staff but did not have this information displayed. The results failed to show a significant beneficial effect of the intervention on pain control, sleep, cancer-related symptoms, or analgesic dosing, but confidence intervals were broad. More research is needed to improve the quality of care for inpatients with cancer-related pain.

Evaluating large and complex demonstrations: the CHAMPUS reform initiative experience. Civilian Health and Medical Program of the Uniformed Services.

OBJECTIVE: To examine the evaluation process for the CHAMPUS Reform Initiative (CRI) both to highlight issues that evaluators must consider when undertaking such projects and to provide policymakers with tools to better assess demonstration project evaluations. DATA SOURCES: The CRI evaluation. STUDY DESIGN: Case study. DATA COLLECTION: Review of CRI evaluation reports. PRINCIPAL FINDINGS: Although policymakers increasingly rely on the evaluations of demonstration projects to determine whether to extend the scope and funding of many public programs, the results of these evaluations are often difficult to assess. Despite its analytical sophistication, the CRI evaluation was no exception. The somewhat artificial time constraints imposed by policymakers made projection of the CRI's performance beyond the demonstration period particularly difficult. CONCLUSIONS: Much uncertainty generally remains even after well-planned and well-executed evaluations of demonstration projects.

Are nonspecific practice guidelines potentially harmful? A randomized comparison of the effect of nonspecific versus specific guidelines on physician decision making.

OBJECTIVE: To test the ability of two different clinical practice guideline formats to influence physician ordering of electrodiagnostic tests in low back pain. DATA SOURCES/STUDY DESIGN: Randomized controlled trial of the effect of practice guidelines on self-reported physician test ordering behavior in response to a series of 12 clinical vignettes. Data came from a national random sample of 900 U.S. neurologists, physical medicine physicians, and general internists. INTERVENTION: Two different versions of a practice guideline for the use of electrodiagnostic tests (EDT) were developed by the U.S. Agency for Health Care Policy and Research Low Back Problems Panel. The two guidelines were similar in content but varied in the specificity of their recommendations. DATA COLLECTION: The proportion of clinical vignettes for which EDTs were ordered for appropriate and inappropriate clinical indications in each of three physician groups were randomly assigned to receive vignettes alone, vignettes plus the nonspecific version of the guideline, or vignettes plus the specific version of the guideline. PRINCIPAL FINDINGS: The response rate to the survey was 71 percent. The proportion of appropriate vignettes for which EDTs were ordered averaged 77 percent for the no guideline group, 71 percent for the nonspecific guideline group, and 79 percent for the specific guideline group (p = .002). The corresponding values for the number of EDTs ordered for inappropriate vignettes were 32 percent, 32 percent, and 26 percent, respectively (p = .08). Pairwise comparisons showed that physicians receiving the nonspecific guidelines ordered fewer EDTs for appropriate clinical vignettes than did physicians receiving no guidelines (p = .02). Furthermore, compared to physicians receiving nonspecific guidelines, physicians receiving specific guidelines ordered significantly more EDTs for appropriate vignettes (p = .0007) and significantly fewer EDTs for inappropriate vignettes (p = .04). CONCLUSIONS: The clarity and clinical applicability of a guideline may be important attributes that contribute to the effects of practice guidelines.

Conditions that justify strikes as perceived by housestaff at a public hospital.

Although physicians' strikes provoke considerable controversy and are increasing in incidence, little information is available regarding house officers' attitudes towards the ethics of striking. To determine house officers' views of whether and when it is justified to strike, and to understand the factors affecting their judgments, in 1988 the authors surveyed 432 residents (including interns and fellows) at a large public hospital shortly following a four-day housestaff work action; 255 (59%) responded. In responding to 12 hypothetical scenarios, 218 residents (85%) thought striking was justified if vital equipment were in short supply and the strike was unlikely to cause lethal harm, but only 10 (4%) thought striking justified if the issue was low salaries and the risk to patients was high. Twenty-two residents (9%) thought striking unacceptable in all 12 cases. Training in obstetrics-gynecology or psychiatry, liberal politics, and low levels of job satisfaction were independent predictors of residents' believing that strikes were more often justified. Although the residents' responses to the hypothetical scenarios were related to their prior work action behaviors, the association was weakened by adjustment for contextual factors such as specialty and social norms. Implications for education in medical ethics are discussed.

The effects of a managed care educational program on faculty and trainee knowledge, attitudes, and behavioral intentions.

PURPOSE: To assess the state of managed care knowledge and attitudes and to evaluate the effects of a two-day course on participants' knowledge, attitudes, and behavioral intentions. METHOD: In 1996, the University of California, Davis, Medical School invited all medical students, residents, faculty, and administrators to participate in one of two sessions of a two-day course on managed care. Participants in the first session were given both pre- and post-course questionnaires. Participants in the second session were given only post-course questionnaires. The questionnaires measured objective knowledge, attitudes, and behavioral intentions. Participants (other than administrators) who completed the questionnaires also received a follow-up questionnaire six months after the seminar. RESULTS: The two sessions were attended by 818 UC Davis medical students, residents, faculty, and administrators: after excluding 33 non-physician administrators, 428 completed survey packets (55%) were available for full analysis. Before the course, participants in the first session correctly answered on average only 46% of 32 questions about managed care knowledge. Course attendance was associated with significant gains in knowledge (to 67% correct, p < .001) and a marked increase in appreciation for the cost-control effectiveness of managed care (from 3.35 to 3.98 on a five-point scale, p < .001). Knowledge gains were greatest among medical students; changes in attitudes and behavioral intentions were least among residents. Among respondents to a follow-up survey, the changes were partially sustained six months later. CONCLUSION: Within this academic medical center, baseline levels of managed care knowledge were low among faculty as well as among trainees, and attitudes reflected a blend of negativism and wishful thinking. An intensive two-day educational program effectively increased knowledge and changed selected attitudes among critical academic constituencies. Other academic medical centers may wish to consider presenting similar programs in order to orient their faculties and trainees to the economic realities of the foreseeable future.

Attitudes and behavioral intentions regarding managed care: a comparison of academic and community physicians.

Physicians' attitudes toward managed care and the impact of these attitudes on behaviors that affect patient care are important factors in managed care reform. In addition, the attitudes of academic physicians may influence their willingness to reform medical education in an effort to prepare students to practice under managed care. Although it is a conventional opinion that the academic health center and its academic physicians are antagonistic toward managed care, there has not been a direct comparison of the attitudes of these physicians to those of practicing community physicians. We used a self-administered questionnaire to assess attitudes toward managed care and behavioral intentions regarding practices related to managed care; a sample of academic physicians (n = 129) was compared with a sample of community physicians (n = 307). Community physicians were less negative in their evaluations of the quality of care in a managed care environment, but no differences were identified between the two groups with regard to the cost-effectiveness, inevitability, or need to adapt to managed care. Academic specialists were more likely than academic primary care physicians to rate managed care as something to which they needed to adapt. Community physicians were less likely to report a willingness to change their referral patterns. Aggregating across practice type, we also uncovered systematic differences between primary care and specialist physicians. The data suggest that opinions about quality and cost-containment in managed care are significant correlates of intentions to change practice behaviors.

Physicians' attitudes toward managed care: assessment and potential effects on practice behaviors.

This study was designed to identify the key components of physicians' attitudes toward managed care and develop a tool to assess these components. We developed a questionnaire based on physicians' reactions to managed care, as reflected in the published literature. We mailed this questionnaire to a sample of 753 community physicians in the greater Sacramento area. A factor analysis of these data (n = 315) identified five unifactorial scales, which we labeled managed care quality, need to adapt to managed care, cost-containment effectiveness of managed care, personal knowledge of managed care, and inevitability of managed care. Physicians were most negative about the quality of managed care and most in agreement about the need to adapt to it. Correlations among these five scales, while statistically significant, were modest in size, suggesting that these physicians were quite discriminating in their evaluations. In comparison with medical/surgical specialists, primary care physicians rated the quality of managed care, their knowledge of it, and the inevitability of a national transition to managed care more positively. These measures predicted the physicians' intentions to alter their medical behaviors to comply with managed care practices.
