RESUMO
Quality of care in the United States and elsewhere consistently fails to meet established standards. These failures subject patients to premature death and needless suffering. Yet, unlike the experience with other threats to life (tire failures or airplane rudders), public and private policymakers have been unable to maintain sufficient interest in identifying and solving problems with quality to change the way in which care is delivered. We discuss why it is hard to keep quality on the policy agenda and suggest short-term steps that are necessary if quality is to improve here and in the rest of the world.

OBJECTIVE: To assess the effect of providing free health care services to low-income adults. METHODS: We measured access to primary care services by enrollees with 4 chronic medical conditions in the General Relief Health Care Program (GRHCP), a program designed for adults receiving General Relief (GR). Implemented by the Los Angeles County Health Department in October 1995, the GRHCP is composed of private and public health care facilities. As adults registered for GR, they were asked to complete a baseline health survey, were enrolled in the GRHCP, and assigned a health care provider. A total of 8520 surveys were completed between September and November 1996 (98% response rate). The analyses of this article are limited to individuals (N = 2164) who reported a history of hypertension, diabetes mellitus, a nonresolving cough, or substance dependence. We reviewed medical records to determine whether new GR recipients had visited their designated GRHCP provider within 4 months of enrollment and used multivariate logistic regression to assess the effect of individual patient factors on the use of free health care. RESULTS: A total of 17% of individuals visited their assigned GRHCP provider within 4 months of enrollment. In multivariate analysis, patients were more likely to have made a visit if they were younger than 50 years, were female, were Asian/Pacific Islander, reported needing to see a physician, or had seen a physician within 12 months. CONCLUSIONS: It is not sufficient to merely supply the name and address of a health care provider to this population. More aggressive efforts should be attempted to increase utilization of services for patients with medical conditions responsive to ambulatory care.

CONTEXT: Continuing changes in the health care delivery system make it essential to monitor underuse of needed care, even for relatively well-insured populations. Traditional approaches to measuring underuse have relied on patient surveys and chart reviews, which are expensive, or simple single-condition claims-based indicators, which are not clinically convincing. OBJECTIVE: To develop a comprehensive, low-cost system for measuring underuse of necessary care among elderly patients using inpatient and outpatient Medicare claims. DESIGN: A 7-member, multispecialty expert physician panel was assembled and used a modified Delphi method to develop clinically detailed underuse indicators likely to be associated with avoidable poor outcomes for 15 common acute and chronic medical and surgical conditions. An automated system was developed to calculate the indicators using administrative data. SETTING AND SUBJECTS: A total of 345,253 randomly selected elderly US Medicare beneficiaries in 1994-1996. MAIN OUTCOME MEASURES: Proportion of beneficiaries receiving care, stratified by indicators of necessary care (n = 40, including 3 for preventive care), and avoidable outcomes (n = 6). RESULTS: For 16 of 40 necessary care indicators (including preventive care indicators), beneficiaries received the indicated care less than two thirds of the time. Of all indicators, African Americans scored significantly worse than whites on 16 and better on 2; residents of poverty areas scored significantly lower than nonresidents on 17 and higher on 1; residents of federally defined Health Professional Shortage Areas scored significantly lower than nonresidents on 16 and higher on none (P<.05 for all). CONCLUSIONS: This claims-based method detected substantial underuse problems likely to result in negative outcomes in elderly populations. Significantly more underuse problems were detected in populations known to receive less-than-average medical care. The method can serve as a reliable, valid tool for monitoring trends in underuse of needed care for older patients and for comparing care across health care plans and geographic areas based on claims data.

CONTEXT: Patients with rheumatoid arthritis are at risk for substantial morbidity because of their arthritis and premature mortality due to comorbid diseases. However, little is known about the quality of the health care that these patients receive. OBJECTIVE: To assess the quality of the health care that rheumatoid arthritis patients receive for their arthritis, comorbid diseases, and health care maintenance and to determine the effect of patterns of specialty care on quality. DESIGN, SETTING, AND PARTICIPANTS: Historical cohort study of 1355 adult rheumatoid arthritis patients enrolled in the fee-for-service or discounted fee-for-service plans of a nationwide US insurance company. Patients were identified and followed up through administrative data between 1991 and 1995. MAIN OUTCOME MEASURES: Quality scores for arthritis, comorbid disease, and health care maintenance were developed from performance on explicit process measures that related to each of these domains and described the percentage of indicated health care processes performed within each domain during each person-year of the study. RESULTS: During 4598 person-years of follow-up, quality scores were 62% (95% confidence interval [CI], 61%-64%) for arthritis care, 52% (95% CI, 49%-55%) for comorbid disease care, and 42% (95% CI, 40%-43%) for health care maintenance. Across domains, care patterns including relevant specialists yielded performance scores 30% to 187% higher than those that did not (P<.001) and 45% to 67% of person-years were associated with patterns of care that did not include a relevant specialist. Presence of primary care without specialty care yielded health care maintenance scores that were 43% higher than those for patterns that included neither primary nor relevant specialty care (P<.001). CONCLUSIONS: In this population, health care quality appears to be suboptimal for arthritis, comorbid disease, and health care maintenance. Patterns of care that included relevant specialists were associated with substantially higher quality across all domains. Patterns that included generalists were associated with substantially higher quality health care maintenance than patterns that included neither a generalist nor a relevant specialist. The optimal roles of primary care physicians and specialists in the care of patients with complex conditions should be reassessed. JAMA. 2000;284:984-992

PURPOSE: To understand the extent to which family planning clinic patients have health insurance or access to other health care providers, as well as their preferences for clinic versus private reproductive medical care. METHOD: An anonymous self-report questionnaire was administered at three Planned Parenthood clinics in Los Angeles County to 780 female patients aged 12-49 years. Dependent variables included insurance status, usual source of care, and a battery of questions regarding the importance of confidentiality. RESULTS: A total of 356 adolescents (aged 12-19 years) and 424 adults (aged 20-49 years) completed the survey in 1994. Fifty-nine percent of adolescents and 53% of adults had a usual source of care other than the clinic. The majority of each group reported some degree of continuity of care in their usual provider setting. Nearly half (49%) of all adolescents had health insurance compared with 27% of adults. Adolescents cited not wanting to involve family members as the primary reason for not using their usual providers, whereas adults were more likely to cite being uninsured. The majority of both adult and adolescent patients indicate they would prefer the clinic over private health care if guaranteed health care that was free, confidential, or both. CONCLUSION: Despite many patients' having health insurance and other sources of health care, family planning clinics were primarily chosen because of cost and confidentiality. Their reasons for preferring clinics may continue despite changes in access to insurance or efforts to incorporate similar reproductive services into mainstream health care provider systems. Making public or private health care funds available to family planning clinics through contracts or other mechanisms may facilitate patients' access to essential services and reduce potential service duplication.

CONTEXT: Information about the performance of hospitals, health professionals, and health care organizations has been made public in the United States for more than a decade. The expected gains of public disclosure have not been made clear, and both the benefits and potential risks have received minimal empirical investigation. OBJECTIVE: To summarize the empirical evidence concerning public disclosure of performance data, relate the results to the potential gains, and identify areas requiring further research. DATA SOURCES: A literature search was conducted on MEDLINE and EMBASE databases for articles published between January 1986 and October 1999 in peer-reviewed journals. Review of citations, public documents, and expert advice was conducted to identify studies not found in the electronic databases. STUDY SELECTION: Descriptive, observational, or experimental evaluations of US reporting systems were selected for inclusion. DATA EXTRACTION: Included studies were organized based on use of public data by consumers, purchasers, physicians, and hospitals; impact on quality of care outcomes; and costs. DATA SYNTHESIS: Seven US reporting systems have been the subject of published empirical evaluations. Descriptive and observational methods predominate. Consumers and purchasers rarely search out the information and do not understand or trust it; it has a small, although increasing, impact on their decision making. Physicians are skeptical about such data and only a small proportion makes use of it. Hospitals appear to be most responsive to the data. In a limited number of studies, the publication of performance data has been associated with an improvement in health outcomes. CONCLUSIONS: There are several potential gains from the public disclosure of performance data, but use of the information by provider organizations for quality improvement may be the most productive area for further research.

OBJECTIVE: To evaluate the association between physician-reported utilization management (UM) techniques in capitated physician groups and physician satisfaction with capitated care. STUDY SETTING: 1,138 primary care physicians from 89 California capitated physician groups in 1995. STUDY DESIGN: Eighty percent of physicians (N = 910) responded to a mail survey regarding the UM policies in their groups and their satisfaction with the care they deliver. Physician-reported UM strategies measured included group-mandated preauthorization (number of referrals requiring preauthorization, referral denial rate, and referral turnaround time), group-provided explicit practice guidelines, and group-delivered educational programs regarding capitated care. We also measured two key dimensions of satisfaction with capitated care (multi-item scales): (1) satisfaction with capitated care autonomy and quality, and (2) satisfaction with administrative burden for capitated patients. EXTRACTION METHODS: We constructed two multivariate linear regression models to examine associations between physician-reported UM strategies and physician satisfaction, controlling for demographic and practice characteristics and adjusting for clustering. PRINCIPAL FINDINGS: Physician-reported denial rate and turnaround time were significantly negatively associated with capitated care satisfaction. Physicians who reported that their groups provided more guidelines were more satisfied on both dimensions, while physicians who reported that their groups sponsored more educational programs were more satisfied with administrative burden. The number of clinical decisions requiring preauthorization was not significantly associated with either dimension of satisfaction. CONCLUSIONS: Physicians who reported that their groups used UM methods that directly affected their autonomy (high denial rates and long turnaround times) were less satisfied with care for capitated patients. However, a preauthorization policy for referrals or tests was not, in and of itself, associated with satisfaction. Indirect control mechanisms such as guidelines and education were positively associated with satisfaction.

PURPOSE: To develop a research agenda for uterine artery embolization (UAE) for the treatment of symptomatic leiomyomata. MATERIALS AND METHODS: An expert panel was convened to examine data and develop a consensus for UAE research. Panelists reviewed data from articles about UAE and data on hysterectomy and myomectomy, which were abstracted into evidence tables. A modified Delphi process was used to rate the importance of measuring specific outcomes and a nominal group process was used to develop ideas for study designs. RESULTS: Panelists agreed that UAE studies would have to examine certain key measures. Outcomes identified as either "important to measure" or "essential to measure" were death, reoperation, operative injury, menorrhagia, premature menopause, recurrence of myomata, and satisfaction. The panel proposed four areas for research: randomized trial, prospective registry, disease-specific quality-of-life instrument, and cost analysis. CONCLUSIONS: Symptomatic uterine leiomyomata are a major health concern for women. New techniques that promise to provide symptom relief deserve careful consideration. Traditionally, surgical procedures have been poorly studied until after they have been widely used. If the process described in this article can guide the acquisition of knowledge in this field, it may serve as a model for evaluating other new technologies before they become widely adopted.

PURPOSE: To determine the extent of overuse and underuse of diagnostic testing for coronary artery disease and whether the socioeconomic status, health insurance, gender, and race/ethnicity of a patient influences the use of diagnostic tests. SUBJECTS AND METHODS: We identified patients who presented with new-onset chest pain not due to myocardial infarction at one of five Los Angeles-area hospital emergency departments between October 1994 and April 1996. Explicit criteria for diagnostic testing were developed using the RAND/University of California, Los Angeles, expert panel method. They were applied to data collected by medical record review and patient questionnaire. RESULTS: Of the 356 patients, 181 met necessity criteria for diagnostic cardiac testing. Of these, 40 (22%) failed to receive necessary tests. Only 7 (3%) of the 215 patients who received some form of cardiac testing had tests that were judged to be inappropriate. Underuse was significantly more common in patients with only a high school education (30% vs 15% for those with some college, P = 0.02) and those without health insurance (34% vs 15% of insured patients, P = 0.01). In a multivariate logistic regression model, only the lack of a post-high school education was a significant predictor of underuse (odds ratio 2.2, 95% confidence interval 1.0 to 4.4). CONCLUSION: Among patients with new-onset chest pain, underuse of diagnostic testing for coronary artery disease was much more common than overuse. Underuse was primarily associated with lower levels of patient education.

OBJECTIVE: To estimate charges attributable to osteoarthritis (OA) in a managed care organization. METHODS: Longitudinal study based on insurance claims incurred and filed between 1991 and 1993 in a national managed care organization. Patients with claims for OA were randomly sampled to yield 20,000 study subjects. Charges per person-year were determined for these patients and compared to those of comparison subjects matched for age, sex, and insurance plan without claims for OA. RESULTS: Total charges per patient-year adjusted to 1993 dollars for patients with OA <65 and > or =65 years of age were $5,294 and $5,704, respectively, while charges for controls were $2,467 and $3,741, respectively. Thus, charges due to OA were $2,827 and $1,963, accounting for 5% of total plan charges. CONCLUSION: Patients with symptomatic OA incur charges for medical care at about twice the rate of plan enrollees without claims for OA and account for a substantial proportion of total charges in a managed care plan.

BACKGROUND: Satisfaction with health plan performance has been assessed frequently, but assessment of physician group performance is rare. OBJECTIVE: To present ratings of the care provided by physician groups to enrollees in a variety of capitated health maintenance organization plans. METHODS: A random sample was drawn of adult enrollees receiving managed health care from 48 physician groups in a group practice association. Each individual in the sample was mailed a 12-page questionnaire and 7093 were returned (59% response rate). The mean age of those returning the questionnaire was 51 years; 65% were women. RESULTS: Reliability estimates for 6 multi-item satisfaction scales were excellent, and noteworthy differences in ratings among groups were observed. In particular, ratings of overall quality ranged from a low of 28 to a high of 68 (mean, 50; SD, 10). Average scores for physician groups were strongly correlated across all scales, but no single group scored consistently highest or lowest on the different scales. Negative ratings of care were significantly related to the following: intention to switch to another physician group, difficulty in getting appointments, lengthy waiting periods in the reception area and examination room, the inability to get consistent care from one physician for routine visits, and not being informed by the office staff when there was a delay in seeing the primary care provider. CONCLUSIONS: Monitoring of health care quality at the physician group level is possible, and could be used for benchmarking, internal quality improvement, and for providing information to the public about how these physician groups will meet its needs.

CONTEXT: Managed care and capitation have placed new responsibilities on primary care physicians, including formally acting as "gatekeepers" for specialty services and tests. Previous studies have not examined whether primary care physicians who provide services to patients under many coverage arrangements feel differently about caring for patients covered under capitation vs those covered through more traditional forms of insurance. An understanding of whether California primary care physicians feel that they deliver a different level of quality to capitated patients could help signal whether variations in care for patients with different coverage forms are evolving. OBJECTIVE: To evaluate whether primary care physicians in California capitated groups report different satisfaction levels with quality of care for patients in their overall practice than for patients covered by capitated contracts and to examine whether physicians' satisfaction with capitated care quality is influenced by the characteristics of the practice setting. DESIGN: Cross-sectional questionnaire. SETTING: A total of 89 California physician groups with capitated contracts. PARTICIPANTS: A total of 910 primary care physicians (80% response rate). MAIN OUTCOME MEASURE: Satisfaction with 4 aspects of quality of care provided to patients covered by capitated contracts vs patients overall. RESULTS: Physicians reported lower satisfaction with all 4 aspects of care for patients covered by capitated contracts than for patients in their overall practice: 71% were very or somewhat satisfied with relationships with capitated patients (compared with 88% for overall practice), 64% were very or somewhat satisfied with the quality of care they provided to capitated patients (compared with 88% for overall practice), 51% were very or somewhat satisfied with their ability to treat capitated patients according to their own best judgment (compared with 79% for overall practice), and 50% were very or somewhat satisfied with their ability to obtain specialty referrals (compared with 59% for overall practice) (P< or =.001 for all comparisons). Being in a medical group practice (vs an independent practice association) and having a larger percentage of capitated patients were independently associated by multivariate analysis with higher levels of satisfaction with capitated quality of care (P< or =.005). CONCLUSION: These California primary care physicians were less satisfied with the quality of care they deliver to patients covered by capitated contracts than with the quality of care they deliver to patients covered by other payment sources. However, those in medical group practices and with a higher percentage of capitated patients were more satisfied with capitated care. National expansion of capitation should be accompanied by efforts to ensure that the satisfaction of practicing physicians with the care they deliver does not decline.

OBJECTIVE: To compare rates of cataract extraction in 2 prepaid health settings and in traditional fee-for-service (FFS) settings. DESIGN: A cross-sectional analysis using 1993 health maintenance organization (HMO) Medicare claims and encounter files, the Health Care Financing Administration (HCFA) 5% Medicare Part B provider/supplier file, and the HCFA October 1992 100% Medicare population file. SETTING: Southern California Medicare FFS settings and the staff-model and independent practice association (IPA) plans of a large California HMO. PATIENTS: 1993 Medicare beneficiaries aged 65 years and older. The study included 43387 staff-model HMO enrollees, 19050 IPA enrollees, and 47 150 FFS beneficiaries (a 5% sample of all Southern California FFS beneficiaries). MAIN OUTCOME MEASURE: Age and risk-factor adjusted rates of cataract extraction per 1000 beneficiary-years. RESULTS: After controlling for age, sex, and diabetes mellitus status, FFS beneficiaries were twice as likely to undergo cataract extraction as were prepaid beneficiaries (P<.01). Female FFS beneficiaries were nearly twice as likely to undergo the procedure as were male FFS beneficiaries (P<.001); there were no extraction rate differences by sex in the prepaid settings. CONCLUSION: Because of the potential implications for vision care in the elderly, the significantly different rates of cataract extraction in FFS and prepaid settings warrant further clinical investigation to determine whether there is overuse in FFS vs underuse in prepaid settings. Such investigations must assess the appropriateness of cataract surgery by evaluating its use relative to clinical need.

OBJECTIVE: Examine the reproducibility of the RAND method for developing criteria for the appropriateness of medical procedures. DESIGN: Comparison of two sets of explicit criteria for appropriateness of upper gastrointestinal (UGI) endoscopy, developed by separate expert panels from two countries. SETTING: United States, Switzerland. STUDY PARTICIPANTS: National experts from different medical specialties involved in the referral or application of UGI endoscopy. INTERVENTIONS: Each panel was presented with about 500 clinical scenarios (indications) that were rated on a nine-point scale as to the appropriateness of performing UGI endoscopy for a patient with that clinical presentation. MAIN OUTCOME MEASURES: (1) distribution of appropriateness ratings and intrapanel agreement categories between the two panels, (2) between-panel agreement of assigning appropriateness for comparable indications and, (3) percentage of indications with major between-panel differences. RESULTS: Ratings for 2/3 of indications could be compared. The Swiss panel showed higher intrapanel agreement (54.6% versus 46.2%, P = 0.002). Seventy-eight per cent of comparable indications were assigned to identical categories of appropriateness by both panels (kappa = 0.76, P < 0.001). For 93% of the 376 comparable indications, there were no major interpanel differences. CONCLUSION: Separate expert panels in different countries, using a standardized methodology, produce criteria for appropriateness of medical procedures that are similar. Given the resources being invested throughout the world in developing criteria and guidelines, international collaboration in seeking optimal use of limited health care resources should be intensified.

BACKGROUND & AIMS: Efforts to reduce costs in health care may raise concerns about underuse of medical procedures. This study prospectively assessed underuse of upper gastrointestinal endoscopy in a cohort of patients in whom we have recently published data on overuse of endoscopy. METHODS: Underuse was identified by formal necessity criteria for endoscopy, obtained by an explicit panel process. Outpatients were consecutively included in two clinical settings. Setting A consisted of 20 primary care physicians and 7215 patient visits that occurred within 1 month. Setting B consisted of 920 visits that occurred during 3 weeks at an outpatient clinic. RESULTS: During these 8135 visits, 611 patients complained of upper digestive symptoms; 63 of them underwent endoscopy. Underuse was identified in 72 patients (11.8%). The two clinical situations mainly responsible for underuse of endoscopy were uninvestigated peptic symptoms resistant to treatment and dysphagia. At first follow-up, 29 of the patients with initial underuse still fulfilled criteria of necessity (underuse rate, 4.7%). One-year follow-up showed underuse of endoscopy in 5 patients. CONCLUSIONS: This prospective evidence shows that underuse of a medical procedure exists. The estimated overuse and underuse of endoscopy in this cohort were approximately equal (5%). Improving quality of care will require reductions of both overuse and underuse of medical procedures.

OBJECTIVE: To estimate the extent of under use of coronary angiography and to determine whether women, ethnic minorities and poor and uninsured patients are less likely than their counterparts to receive necessary coronary angiography. DESIGN: Retrospective cohort study employing chart review and patient interviews. SETTING: Four teaching hospitals: three government owned (public) and one private university medical center in Los Angeles, California. PATIENTS: Three hundred and fifty two patients who had a positive exercise stress test between 1 January 1990 and 30 June 1991 and met explicitly defined criteria for the necessity of coronary angiography established by a multidisciplinary expert panel. MAIN OUTCOME MEASURES: Percentage of patients who received necessary coronary angiography within 3 and 12 months following exercise stress testing, adjusted for demographic and clinical characteristics using logistic regression. RESULTS: Overall 43% received necessary coronary angiography within 3 months and 56% within 12 months of the stress test. Women were less likely than men to receive necessary coronary angiography. Adjusted odds ratio (AOR) 0.54, 95% confidence interval (CI) 0.34-0.90 for angiography within 3 months of the stress test; AOR 0.47, 95% CI 0.29-0.77 for angiography within 12 months of the stress test. Public hospital patients underwent necessary coronary angiography less often than private hospital patients. AOR 0.40, 95% CI 0.23-0.79 for within 3 months; AOR 0.52, 95% CI 0.30-0.91 for within 12 months. CONCLUSIONS: Under use of coronary angiography can be measured and occurs to a significant degree. It is important to develop standards of quality to address and safeguard against under use of necessary medical care.

OBJECTIVES: Previous studies have found that health-status measures may be unable to detect clinically important changes for patients whose baseline health is poor (the "floor phenomenon"). It is not known whether this inability to detect change is confined to patients in very poor baseline health or whether the sensitivity of health-status instruments varies across the entire range of health states. The goals of this study were to see how changes in physical health, mental health, and overall health (1) depend on baseline (usual) health and (2) compare with patients' global assessment of changes in their health. METHODS: Stable, ambulatory patients presenting to the emergency department of a public hospital retrospectively rated their usual physical health (eight items), mental health (three items), and overall health (one item); their health on the day of study entry using these same items; and their global assessment of the change in their health compared with baseline. Complete information on these items was available for 1,005 patients. Baseline scores on the physical and mental health subscales and the overall health item were divided into five categories: 81 to 100 (best), 61 to 80, 41 to 60, 21 to 40, and 0 to 20 (worst). RESULTS: The mean difference in health from baseline to emergency department presentation decreased as the baseline health category worsened, as follows: physical health, -26.0, -35.9, -15.1, -9.5, +1.0; mental health, -23.0, -16.1, -9.6, 0.0, 6.6; overall health -64.0, -45.3, -28.4, -8.4, 10.4, respectively. However, patients' global assessment of health change showed the opposite trend; the proportion of patients rating their health as "much worse" than baseline increased as baseline health worsened. When only patients whose physical health score declined less than 10 points were analyzed, 14% of those in the best baseline health said their health was "much worse," whereas 74% of those with the worst baseline physical health said their health was "much worse" than baseline. CONCLUSIONS: These findings suggest that the sensitivity of health-status measures to change and the meaning of an incremental change in physical health or mental health vary depending on baseline health. This may result from noninterval properties of response options or from patients being at the lowest health state (the "floor") of individual questions. If health-status measures similar to this are to be used to compare the outcomes of treatment across diseases and for patients in a wide variety of baseline health states, weighting schemes may be needed to account for these effects.

STUDY OBJECTIVE: To determine whether race/ethnicity is an important determinant of emergency department use. METHODS: We conducted a cross-sectional survey in a public ED to determine self-reported ED visits over the preceding 3 months. The study group comprised consecutive ambulatory patients (N = 1,049) with nonemergency medical problems. RESULTS: Blacks, whites, and Hispanics were equally likely to report one or more visits to an ED in the 3 months before study enrollment. Blacks were the most likely to report two or more ED visits in the preceding 3 months (19.0%), followed by whites (13.5%) and Hispanics (11.4%) (P = .01; unadjusted odds ratio, 1.82 for blacks versus Hispanics). In multivariate analysis, older age (P < .001), health insurance coverage (P < .001), regular source of care (P < .001), and difficulty obtaining transportation to a physician's office (P = .011) were positively associated with two or more previous ED visits. After adjustment for these variables, race/ethnicity was not significantly associated with ED use (P = .23; adjusted odds ratio for blacks versus Hispanics, 1.48 [95% confidence interval, .95 to 2.30]). CONCLUSION: Race/ethnicity was not an important determinant of ED use after adjustment for age, health insurance coverage, regular source of care, and barriers to health care. Population-based studies of ED use should be conducted to further evaluate whether racial/ethnic differences in ED use exist that are not explained by differences in demographics, health, socioeconomic status, access to care, or other determinants of ED use.
