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.

Direct-to-consumer prescription drug advertising, 1989-1998. A content analysis of conditions, targets, inducements, and appeals.

BACKGROUND: We conducted a content analysis of consumer-targeted prescription drug advertisements to explore trends in prevalence, shifts in the medical conditions for which drugs are promoted, reliance on financial and nonmonetary inducements, and appeals used to attract public interest. METHODS: We collected the drug advertisements appearing in 18 consumer magazines from 1989 through 1998. Two judges independently coded each advertisement and placed it in a category pertaining to the target audience, use of inducements, and product benefits (mean kappa=0.93). We employed descriptive statistics, cross-tabulations, and curve estimation procedures. RESULTS: A total of 320 distinct advertisements were identified, representing 101 brands and 14 medical conditions. New advertisement and brand introductions increased dramatically during this decade. Advertisements for drugs used for dermatologic, human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), and obstetric/gynecologic conditions were most common. Almost all of the advertisements were aimed at the potential user of the drug, not third-party intermediaries such as parents and spouses. Although most advertisements were gender-neutral, women were more likely to be exclusively targeted. One eighth of the advertisements offered a monetary incentive (eg, a rebate or money-back guarantee), and one third made an offer of additional information in printed or audio/video form. The most common appeals used were effectiveness, symptom control, innovativeness, and convenience. CONCLUSIONS: Consumer-directed prescription drug advertising has increased dramatically during the past decade. The pharmaceutical industry is turning to this type of advertising to generate interest in its products. Our data may be useful to physicians who want to stay abreast of the treatments that are being directly marketed to their patients.

Providing managed care options for a large population: evaluating the CHAMPUS reform initiative. Civilian Health and Medical Program of the Uniformed Services.

OBJECTIVES: To evaluate a managed care demonstration project in CHAMPUS (Civilian Health and Medical Program of the Uniformed Services), the insurance program covering physical and mental health care services for the dependents of active duty military personnel, military retirees, and the retirees' dependents. The demonstration project added a health maintenance organization (HMO) option and a preferred provider organization (PPO) option to the standard CHAMPUS coverage and allowed beneficiaries to select the coverage option they preferred. DATA SOURCES: Utilization, costs, access, and beneficiary satisfaction were measured using data from CHAMPUS claims records, the Defense Enrollment Eligibility Reporting System, the demonstration project contractor's HMO enrollment file, the contractor's list of network hospitals, and two surveys of CHAMPUS beneficiaries. STUDY DESIGN: Changes in utilization at 11 demonstration sites were compared with changes in utilization at 11 matched control sites. The effect of the demonstration project on costs was evaluated by estimating the costs for the demonstration sites both with and without the managed care options based on data from the control sites. Access to care and satisfaction were compared between the demonstration sites and control sites based on beneficiary surveys. DATA COLLECTION: All claims in both demonstration and control sites were used in estimating utilization changes. Two mailed surveys were sent to a randomly selected sample of active duty and retiree households with CHAMPUS beneficiaries; the sample was stratified by beneficiary type (active duty or retiree) and site. PRINCIPLE FINDINGS: Overall utilization in the CHAMPUS system decreased at the demonstration sites but stayed approximately the same at the control sites. Utilization among the enrollees in the HMO demonstration option, however, increased dramatically. Patient access to care and satisfaction generally remained at the same levels at both demonstration and control sites, but enrollees in the HMO option reported higher satisfaction. Costs to the government at the demonstration areas, based on regression estimates from the control sites, were about the same or slightly higher than what they would have been under the standard CHAMPUS system. CONCLUSIONS: Managed care plans for large government-sponsored insurance programs can reduce utilization and maintain patient access and satisfaction. Careful structuring of such plans is needed, however, if they are to reduce costs.

The educational value of consumer-targeted prescription drug print advertising.

BACKGROUND: The case for direct-to-consumer (DTC) prescription drug advertising has often been based on the argument that such promotions can educate the public about medical conditions and associated treatments. Our content analysis of DTC advertising assessed the extent to which such educational efforts have been attempted. METHODS: We collected advertisements appearing in 18 popular magazines from 1989 through 1998. Two coders independently evaluated 320 advertisements encompassing 101 drug brands to determine if information appeared about specific aspects of the medical conditions for which the drug was promoted and about the treatment (mean kappa reliability=0.91). We employed basic descriptive statistics using the advertisement as the unit of analysis and cross-tabulations using the brand as the unit of analysis. RESULTS: Virtually all the advertisements gave the name of the condition treated by the promoted drug, and a majority provided information about the symptoms of that condition. However, few reported details about the condition's precursors or its prevalence; attempts to clarify misconceptions about the condition were also rare. The advertisements seldom provided information about the drug's mechanism of action, its success rate, treatment duration, alternative treatments, and behavioral changes that could enhance the health of affected patients. CONCLUSIONS: Informative advertisements were identified, but most of the promotions provided only a minimal amount of information. Strategies for improving the educational value of DTC advertisements are considered.

Reasons for outpatient referrals from generalists to specialists.

OBJECTIVE: To determine the relative importance of medical and nonmedical factors influencing generalists' decisions to refer, and of the factors that might avert unnecessary referrals. DESIGN: Prospective survey of all referrals from generalists to subspecialists over a 5-month period. SETTING: University hospital outpatient clinics. PARTICIPANTS: Fifty-seven staff physicians in general internal medicine, family medicine, dermatology, orthopedics, gastroenterology, and rheumatology. MEASUREMENTS AND MAIN RESULTS: For each referral, the generalist rated a number of medical and nonmedical reasons for referral, as well as factors that may have helped avert the referral; the specialist seeing the patient then rated the appropriateness, timeliness, and complexity of the referral. Both physicians rated the potential avoidability of the referral by telephone consultation. Generalists were influenced by a combination of both medical and nonmedical reasons for 76% of the referrals, by only medical reasons in 20%, and by only nonmedical reasons in 3%. In 33% of all referrals, generalists felt that training in simple procedures or communication with a generalist or specialist colleague would have allowed them to avoid referral. Specialists felt that the vast majority of referrals were timely (as opposed to premature or delayed) and of average complexity. Although specialists rated most referrals as appropriate, 30% were rated as possibly appropriate or inappropriate. Generalists and specialists failed to agree on the avoidability of 34% of referrals. CONCLUSIONS: Generalists made most referrals for a combination of medical and nonmedical reasons, and many referrals were considered avoidable. Increasing procedural training for generalists and enhancing informal channels of communication between generalists and subspecialists might result in more appropriate referrals at lower cost.

Direct-to-consumer prescription drug advertising and the public.

OBJECTIVE: Drug manufacturers are intensely promoting their products directly to consumers, but the impact has not been widely studied. Consumers' awareness and understanding of, attitudes toward, and susceptibility to direct-to-consumer (DTC) drug advertising were examined. DESIGN: Random-digit dialing telephone survey with a random household member selection procedure (completion and response rates, 58% and 69%, respectively). SETTING: Respondents were interviewed while they were at their residences. PARTICIPANTS: Complete data were obtained from 329 adults in Sacramento County, California. MEASUREMENTS AND MAIN RESULTS: Outcome measures included awareness of advertisements for 10 selected drugs, misconceptions about DTC advertising, attitudes toward DTC ads, and behavioral responses to such promotions. The influence of demographic characteristics, health status, attitudes, beliefs, and media exposure on awareness and behaviors was examined. On average, respondents were aware of advertisements for 3.7 of the 10 drugs; awareness varied from 8% for Buspar (buspirone) to 72% for Claritin (loratadine). Awareness was associated with prescription drug use, media exposure, positive attitudes toward DTC advertising, poorer health, and insurance status. Substantial misconceptions were revealed; e.g., 43% thought that only "completely safe" drugs could be advertised. Direct-to-consumer advertisements had led one third of respondents to ask their physicians for drug information and one fifth to request a prescription. CONCLUSIONS: Direct-to-consumer advertisements are reaching the public, but selectively so, and affecting their behaviors. Implications for public policy are examined.

Advertisement-induced prescription drug requests: patients' anticipated reactions to a physician who refuses.

BACKGROUND: Drug manufacturers increasingly encourage patient prescription drug demand through the use of direct-to-consumer (DTC) advertisements. We describe patients' forecasts of their reactions if their doctor were to deny an advertisement-motivated drug request and then identify significant predictors of these reactions. METHODS: We conducted a random phone survey of 329 Sacramento adults (response rate = 69%). Key outcomes were respondents' perceived likelihood of reacting to the nonfulfillment of a prescription request by becoming disappointed, trying to persuade the physician to reconsider, seeking a prescription from a different physician, and changing physicians. We also assessed associations between the likelihood of these reactions and respondents' evaluations of their physician's communication skills; attitudes toward, assumptions about the regulation of, and past responses to DTC advertising; health status; and demographic characteristics. RESULTS: Disappointment was the most likely reaction (46%). One fourth of the respondents anticipated resorting to persuasion and seeking the prescription elsewhere, while only 15% considered terminating their relationship with their physicians. Subjects who anticipated reacting in these 4 ways reported lower satisfaction with their physicians, evaluated DTC advertising more favorably, and possessed more confidence in the government's regulation of these advertisements. CONCLUSIONS: A sizable fraction of patients believed they would react negatively if their physician refused to provide a prescription for a drug advertised in the general media. Avenues for dealing effectively with patients' advertising-induced requests for prescription drugs are needed.

A taxonomy of requests by patients (TORP): a new system for understanding clinical negotiation in office practice.

BACKGROUND: The goal of our investigation was to facilitate research on clinical negotiation between patients and physicians by developing a reliable and valid classification system for patients' requests in office practice. METHODS: We developed the Taxonomy of Requests by Patients (TORP) using input from researchers, clinicians, and patient focus groups. To assess the system's reliability and validity, we applied TORP to audiotaped encounters between 139 patients and 6 northern California internists. Reliability was assessed with the kappa statistic as a measure of interrater agreement. Face validity was assessed through expert and patient judgment of the coding system. Content validity was examined by monitoring the incidence of unclassifiable requests. Construct validity was evaluated by examining the relationship between patient requests and patient health status; patient request fulfillment and patient satisfaction; and patient requests and physician perceptions of the visit. RESULTS: The 139 patients made 772 requests (619 requests for information and 153 requests for physician action). Average interrater agreement across a sample of 40 cases was 94% (kappa = 0.93; P <.001). Patients with better health status made fewer requests (r = -0.17; P = .048). Having more chronic diseases was associated with more requests for physician action (r = 0.32; P = .0002). Patients with more unfulfilled requests had lower visit satisfaction (r = -0.32; P <.001). More patient requests was also associated with physician reports of longer visit times (P = .016) and increased visit demands (P = .006). CONCLUSIONS: Our study provides evidence that TORP is a reliable and valid system for capturing and categorizing patients' requests in adult primary care. Further research is needed to confirm the system's validity, expand its applicability, and explore its usefulness as a tool for studying clinical negotiation.

Effect of a large managed care program on emergency department use: results from the CHAMPUS reform initiative evaluation.

STUDY OBJECTIVE: To determine the effect of the CHAMPUS Reform Initiative (CRI) on emergency department use and charges, and to ascertain whether any reductions were concentrated among repeat users of the ED, those with less serious ED diagnoses, or those with selected chronic medical conditions. METHODS: Participants were approximately 1.2 million beneficiaries of the Civilian Health and Medical Program of Uniformed Services (CHAMPUS) residing within either 11 military hospital catchment areas in California and Hawaii ("demonstration areas") or 11 matched control areas in other parts of the United States. Under CRI, participants were offered a choice of the standard CHAMPUS indemnity plan, a Preferred Provider Organization-type plan, or a network-model Health Maintenance Organization plan. Beneficiaries were encouraged to use alternatives to the ED for nonemergency conditions. Visits to civilian EDs during two 12-month periods, before and after institution of CRI, were compared. RESULTS: Under CRI, the number of CHAMPUS ED visits decreased by approximately 40% relative to the control, and allowed charges fell by almost 50%. Relative reductions in ED use under CRI were seen among both frequent and infrequent users of the ED. ED case-mix severity increased modestly relative to control (+3.5% versus +.9%). ED use among patients with diabetes, hypertension, and asthma fell sharply in the demonstration areas (by 14% to 41%) but rose in control areas (by 4% to 9%). CONCLUSION: In one of the largest managed care demonstrations ever conducted, a nonintrusive use management program and improved access to outpatient care appeared to reduce ED use, allowed charges, and costs to the government. Reductions in ED use were concentrated to some extent among repeat users and patients with less severe illnesses and were effected without capitation of provider groups or strict gatekeeping requirements.

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.

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.

Measuring the clinical consistency of panelists' appropriateness ratings: the case of coronary artery bypass surgery.

OBJECTIVE: To assess the clinical consistency of expert panelists' ratings of appropriateness for coronary artery bypass surgery. DESIGN: Quantitative analysis of panelists' ratings. PARTICIPANTS: Nine physicians (three cardiothoracic surgeons, four cardiologists, and two internists) convened by RAND to establish criteria for the appropriateness of coronary artery bypass surgery. MAIN OUTCOMES MEASURES: Percentage of indication-pairs given clinically inconsistent ratings (i.e. higher rating assigned to one member of an indication-pair when rating should have been equal or lower). RESULTS: In the final round of appropriateness ratings, among 1785 pairs of indications differing only on a single clinical factor (e.g., three-vessel vs. two-vessel stenosis), 6.6% were assigned clinically inconsistent ratings by individual panelists, but only 2.7% received inconsistent ratings from the panel as a whole (using the median panel rating as the criterion). Internists on the panel provided fewer inconsistent ratings (4.6%) than either cardiologists (7.8%) or cardiothoracic surgeons (6.3%) (p < 0.001). More inconsistencies were noted when the factor distinguishing otherwise identical indications was symptom severity (inconsistency rate, 13.2%) or intensity of medical therapy (13.2%) than when it was number of stenosed vessels (3.8%) or proximal left anterior descending (PLAD) involvement (1.9%). Contrary to expectations, panelists' inconsistency rates increased between the initial and final rounds of appropriateness ratings (from 3.9 to 6.6%, p < 0.001). Panelists' mean ratings across indications were only weakly correlated with individual inconsistency rates (r = 0.18, p = ns). CONCLUSIONS: The RAND/UCLA method for assessing the appropriateness of coronary revascularization generally produces criteria that are clinically consistent. However, research is needed to understand the sources of panelists' inconsistencies and to reduce inconsistency rates further.

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.

Measuring and averting underuse of necessary cardiac procedures: a summary of results and future directions.

BACKGROUND: Attempting to explain the marked variation in utilization of medical procedures has vexed health policy analysts for nearly three decades. Most health services research to date has been directed at identifying and reducing excessive utilization. Little attention has been given to underuse of care. THE LOS ANGELES CARDIAC UNDERUSE PROJECT OVERVIEW: A research group at the University of California, Los Angeles (UCLA), performed two separate, published studies seeking to measure underuse of coronary angiography and coronary artery revascu-larization (bypass surgery and angioplasty), two critical links in the chain of care leading from initial diagnosis of coronary artery disease to definitive treatment. In each study, the necessity criteria developed by the panel were used to identify patients needing an invasive procedure. RESULTS: Within this population of patients (sampled predominantly from public hospitals), substantial underuse of clinically necessary coronary angiography (41% without refusers) and revascularization (23% without refusers) was detected. In this select population of patients, receiving a necessary revascularization procedure appeared to both reduce the risk of death and improve quality of life. DISCUSSION: Despite limitations of the method, detection of underuse is feasible, valid, and affordable in the context of overall health care expenditures. Moreover, the case for implementing "underuse prevention" systems is increasingly compelling. Measuring and disseminating data on underuse of expensive but highly beneficial procedures would provide health care consumers (patients and employers) with useful information and enable health care providers to develop quality improvement strategies aimed at rational use of health care resources.

Assessing patients' expectations in ambulatory medical practice. Does the measurement approach make a difference?

To compare three different approaches to the measurement of patients' expectations for care, we conducted a randomized controlled trial. Medical outpatients (n = 318) of a small (six-physician), single-specialty (internal medicine), academically affiliated private practice in Sacramento, California, were contacted by telephone the night before a scheduled office visit and enrolled over a 5-month period in early 1994. Patients were randomly assigned to receive: (1) a self-administered, structured, previsit questionnaire combined with a postvisit questionnaire; (2) an interviewer-administered, semistructured, previsit interview combined with a postvisit questionnaire; or (3) a postvisit questionnaire only. We assessed the number and content of patients' expectations by previsit questionnaire versus interview; the interaction between sociodemographic characteristics and survey method in predicting number of reported expectations; the effect of unfulfilled expectations elicited by questionnaire and interview on visit satisfaction; and the effect of unfulfilled expectations elicited directly and indirectly on visit satisfaction. Patients reported more expectations by structured questionnaire than semistructured interview (median 12 vs 3, p = .0001). Although there was no main effect of sociodemographic characteristics on expectations, nonwhite patients reported more expectations than white patients by questionnaire and fewer by interview. The number of interventions desired before the visit but not received (indirectly reported unfulfilled expectations) was associated with lower visit satisfaction regardless of whether a questionnaire or interview was used to elicit previsit expectations (p value for the interaction between number of expectations and survey method, > .20). Having more indirectly reported unfulfilled expectations was significantly associated with lower visit satisfaction even after controlling for the number of directly reported unfulfilled expectations (p = .021), but the incremental change in classification accuracy was small (increase in receiver-operating characteristic curve area, 3%). In conclusion, studies of patients' expectations for care must content with a substantial "method effect." In this study from a single group practice, patients checked off more expectations using a structured questionnaire than they disclosed in a semistructured interview, but both formats predicted visit satisfaction. Asking patients about interventions received in relation to their previsit expectations added little to simply asking them directly about omitted care. The interaction of survey method with ethnicity and other sociodemographic characteristics requires further study.
