Providing consumers with information about the quality of health plans: the Consumer Assessment of Health Plans demonstration in Washington State.
BACKGROUND: In 1995 the Agency for Health Care Policy and Research began a five-year project, Consumer Assessment of Health Plans (CAHPS), to create instruments to collect data from consumers about their health care experiences, to develop sophisticated methods to convey these data to consumers, and to evaluate the value of these data to consumers who are selecting health plans. Results were obtained from one of the first CAHPS demonstration sites, the Washington State Health Care Authority. METHODS: The survey was distributed in May-June 1997 to 15,885 enrollees in 20 health plans; 8,204 (51.6%) surveys were completed. Survey results were summarized in a report that described the performance of plans, which was distributed to 97,000 enrollees, and reactions to the report were obtained from more than 1,500 individuals. RESULTS: Nearly everyone who was mailed the report said they saw it. A large proportion said they read most or all of it, and most thought the report was easy to understand, contained information needed to rate plans, and was helpful to learning about differences between plans. Those who used the CAHPS performance report were more likely to switch plans and to report that they were confident they had selected the best plan for their situation. DISCUSSION: The study was unique in that it attempted to evaluate whether employees read the performance report, how they reacted to it, and whether reading it influenced their decision to switch plans or their confidence that they had selected a suitable plan. Choosing a new plan probably stimulated more intense scrutiny of the report than not anticipating switching.

The effect of patients' preferences on racial differences in access to renal transplantation.
BACKGROUND: In the United States, black patients undergo renal transplantation less often than white patients, but few studies have directly assessed the association between race and patients' preferences with respect to transplantation. METHODS: To assess preferences with respect to transplantation and experiences with medical care, we interviewed 1392 (82.9 percent) of 1679 eligible patients with end-stage renal disease (age range, 18 to 54 years) approximately 10 months after they had begun maintenance treatment with dialysis. Participants were selected from a stratified random sample of patients undergoing dialysis in four regions of the United States (Alabama, southern California, Michigan, and the mid-Atlantic region of Maryland, Virginia, and the District of Columbia) in 1996 and 1997. Patients were followed until March 1999. RESULTS: The interviews were conducted with 384 black women, 354 white women, 337 black men, and 317 white men. Black patients were less likely than white patients to want a transplant (76.3 percent of black women reported such a preference, vs. 79.3 percent of white women, and 80.7 percent of black men vs. 85.5 percent of white men), and they were less likely to be very certain about this preference (58.3 percent vs. 65.3 percent and 64.1 percent vs. 75.7 percent, respectively; P<0.01 for each comparison with both sexes combined). However, much larger differences were evident in rates of referral for evaluation at a transplantation center (50.4 percent for black women vs. 70.5 percent for white women, and 53.9 percent for black men vs. 76.2 percent for white men; P<0.001 for each comparison) and placement on a waiting list or transplantation within 18 months after the start of dialysis therapy (31.3 percent for black women vs. 56.5 percent for white women, and 35.3 percent for black men vs. 60.6 percent for white men; P<0.001). These racial differences remained significant after adjustment for patients' preferences and expectations about transplantation, sociodemographic characteristics, the type of dialysis facility, perceptions of care, health status, the cause of renal failure, and the presence or absence of coexisting illnesses. CONCLUSIONS: In the United States, the preferences and expectations with respect to renal transplantation among patients with end-stage renal disease differ according to race. These differences, however, explain only a small fraction of the substantial racial differences in access to transplantation. Physicians should ensure that black patients who desire renal transplantation are fully informed about it and are referred for evaluation.

Quality management practices in Medicaid managed care: a national survey of Medicaid and commercial health plans participating in the Medicaid program.
CONTEXT: Rapid expansion of Medicaid managed care has raised concerns about the capacity and willingness of health plans enrolling Medicaid beneficiaries to provide high-quality care. Recently, legislation has facilitated market entry of Medicaid plans, health plans that draw most of their enrollment from the Medicaid population. OBJECTIVE: To characterize and compare the organizational characteristics and programs related to quality of care of commercial and Medicaid health plans that participate in the Medicaid program. DESIGN: Cross-sectional survey conducted September 1997 to April 1998. SETTING: The Medicaid program in 11 states and the District of Columbia. PARTICIPANTS: All 154 health plans in these localities that provided prepaid general medical care to Medicaid beneficiaries during June 1997, of which 130 (84%) responded to the survey. MAIN OUTCOME MEASURES: Health plan reports of structural characteristics, services offered, performance measurement and feedback, disease management programs, information systems capabilities, and provider network composition and relationships. RESULTS: Half of the respondents were Medicaid plans, with 75% or more of enrollees drawn from the Medicaid population. Medicaid plans tended to be smaller and newer than commercial plans that also served the Medicaid population and had more enabling programs targeting the special needs of the Medicaid population, such as inadequate transportation (85% of Medicaid plans vs 62% of commercial plans; P = .003) and illiteracy (66% vs 38%, respectively; P = .002). Overall, 71% of Medicaid plans vs 43% of commercial plans had enabling programs targeted at 6 or more of the 8 special needs we specified (P = .001). While commercial plans had a higher proportion of board-certified primary care physicians (81% vs 73%; P = .01), we found no major differences between Medicaid plans and commercial plans in collection and dissemination of performance measures, designation of specific areas for quality improvement, or use of disease management programs targeted at conditions prevalent in the Medicaid population. Neither commercial nor Medicaid plans reported high success in improving quality of care. CONCLUSIONS: Based on our survey, while Medicaid plans resemble commercial plans serving the Medicaid population in many aspects of quality management, they are more likely to target programs directed to the specific needs of the Medicaid population. Neither commercial nor Medicaid plans have notably strong records in actual quality improvement.

Hospital readmissions and quality of care.
BACKGROUND: Readmission rates are often proposed as markers for quality of care. However, a consistent link between readmissions and quality has not been established. OBJECTIVE: To test the relation of readmission to quality and the utility of readmissions as hospital quality measures. SUBJECTS: One thousand, seven hundred and fifty-eight Medicare patients hospitalized in four states between 1991 to 1992 with pneumonia or congestive heart failure (CHF). DESIGN: Case control. MEASURES: Related adverse readmissions (RARs), defined as readmissions that indicate potentially sub-optimal care during initial hospitalization, were identified from administrative data using readmission diagnoses and intervening time periods designated by physician panels. We used linear regression to estimate the association between implicit and explicit quality measures and readmission status (RARs, non-RAR readmissions, and nonreadmissions), adjusting for severity. We tested whether RARs were associated with inferior care and performed simulations to determine whether RARs discriminated between hospitals on the basis of quality. RESULTS: Compared with nonreadmitted pneumonia patients, patients with RARs had lower adjusted quality measured both by explicit (0.25 standardized units, P = 0.004) and implicit methods (0.17, P = 0.047). Adjusted differences for CHF patients were 0.17 (P = 0.048) and 0.20 (P = 0.017), respectively. In some analyses, patients with non-RAR readmissions also experienced lower quality. However, rates of inferior quality care did not differ significantly by readmission status, and simulations identified no meaningful relationship between RARs and hospital quality of care. CONCLUSIONS: RARs are statistically associated with lower quality of care. However, neither RARs nor other readmissions appear to be useful tools for identifying patients who experience inferior care or for comparing quality among hospitals.

Quality of care by race and gender for congestive heart failure and pneumonia.
BACKGROUND: Variations in the rates of major procedures by race and gender are well described, but few studies have assessed the quality of care by race and gender for basic hospital services. OBJECTIVE: To assess quality of care by race and gender. RESEARCH DESIGN: Retrospective review of medical records. SUBJECTS: Stratified random sample of 2,175 Medicare beneficiaries hospitalized for congestive heart failure or pneumonia in Illinois, New York, and Pennsylvania during 1991 and 1992. MEASURES: Explicit process criteria and implicit review by physicians. RESULTS: In adjusted analyses, black patients with congestive heart failure or pneumonia received lower quality of care overall than other patients with these conditions by both explicit process criteria and implicit review (P < 0.05). On explicit measures, overall quality of care did not differ by gender for either condition, but significant differences were noted on explicit subscales. Women received worse cognitive care than men from physicians for both conditions, better cognitive care from nurses for pneumonia, and better therapeutic care for congestive heart failure (P < 0.05). Women received worse quality of care than men by implicit review (P = 0.03) for congestive heart failure but not pneumonia. CONCLUSIONS: Consistent racial differences in quality of care persist in basic hospital services for two common medical conditions. Physicians, nurses, and policy makers should strive to eliminate these differences. Gender differences in quality of care are less pronounced and may vary by condition and type of provider or service.

Rolling down the runway: the challenges ahead for quality report cards.
Today, steadily increasing numbers of hospitals and health plans are publicly releasing performance reports on the quality of care to permit comparisons across different providers. Our experience in recent years has provided important new evidence of what public quality reporting can accomplish and the difficulties it faces. Several years ago, the most important impediments to quality reporting may have been the availability of acceptable quality indicators and the feasibility of voluntary, standardized data collection by health plans. We have made strides in these areas. The Health Employer Data and Information Set (HEDIS) has expanded, and there have been new innovations in collecting data on quality from both patients and physicians. Hundreds of health plans have begun to report standardized quality data on a routine basis either voluntarily or in response to requirements from the Health Care Financing Administration, state Medicaid agencies, or private payers. Now, the more formidable barriers to the use of quality report cards may relate to the ways we report the data and use it. We need to find acceptable middle ground for those who believe information on individual physicians is critical and those who believe it is harmful. We need to reap the advantages in different modalities of data collection and different tools for quality management. Most of all, we need to find better ways to use quality reporting to empower purchasers and consumers and improve quality of care.

Use of public performance reports: a survey of patients undergoing cardiac surgery.
CONTEXT: Publicly released performance reports ("report cards") are expected to foster competition on the basis of quality. Proponents frequently cite the need to inform patient choice of physicians and hospitals as a central element of this strategy. OBJECTIVE: To examine the awareness and use of a statewide consumer guide that provides risk-adjusted, in-hospital mortality ratings of hospitals that provide cardiac surgery. DESIGN: Telephone survey conducted in 1996. SETTING: Pennsylvania, where since 1992, the Pennsylvania Consumer Guide to Coronary Artery Bypass Graft [CABG] Surgery has provided risk-adjusted mortality ratings of all cardiac surgeons and hospitals in the state. PARTICIPANTS: A total of 474 (70%) of 673 eligible patients who had undergone CABG surgery during the previous year at 1 of 4 hospitals listed in the Consumer Guide as having average mortality rates between 1% and 5% were successfully contacted. MAIN OUTCOME MEASURES: Patients' awareness of the Consumer Guide, their knowledge of its ratings, their degree of interest in the report, and barriers to its use. RESULTS: Ninety-three patients (20%) were aware of the Consumer Guide, but only 56 (12%) knew about it before surgery. Among these 56 patients, 18 reported knowing the hospital rating and 7 reported knowing the surgeon rating, 11 said hospital and/or surgeon ratings had a moderate or major impact on their decision making, but only 4 were able to specify either or both correctly. When the Consumer Guide was described to all patients, 264 (56%) were "very" or "somewhat" interested in seeing a copy, and 273 (58%) reported that they probably or definitely would change surgeons if they learned that their surgeon had a higher than expected mortality rate in the previous year. A short time window for decision making and a limited awareness of alternative hospitals within a reasonable distance of home were identified as important barriers to use. CONCLUSIONS: Only 12% of patients surveyed reported awareness of a prominent report on cardiac surgery mortality before undergoing cardiac surgery. Fewer than 1% knew the correct rating of their surgeon or hospital and reported that it had a moderate or major impact on their selection of provider. Efforts to aid patient decision making with performance reports are unlikely to succeed without a tailored and intensive program for dissemination and patient education.

Quality management by state Medicaid agencies converting to managed care: plans and current practice.
CONTEXT: Enrollment in Medicaid managed care plans has increased more than 5-fold in this decade, but how states monitor and encourage quality of care in these programs is not known. OBJECTIVE: To characterize the quality monitoring and assurance activities of state Medicaid agencies for Medicaid beneficiaries enrolled in comprehensive prepaid managed care programs. DESIGN: Structured telephone survey conducted between October 1996 and January 1997. SETTING: State Medicaid agencies. PARTICIPANTS: Representatives from all state Medicaid agencies, including the District of Columbia, with beneficiaries enrolled in comprehensive prepaid managed care plans as of July 1, 1996. MAIN OUTCOME MEASURES: Proportion of states with specific quality monitoring and assurance activities for Medicaid managed care. RESULTS: We surveyed all 34 states enrolling beneficiaries in comprehensive managed care programs. In 1996, all 34 states enrolled the population receiving assistance from the Aid to Families With Dependent Children (AFDC) program, while only 21 (62%) and 15 (44%) enrolled the disabled and elderly populations, respectively. In the period 1995 to 1996, 19 states (63%) collected data on satisfaction with care, and 25 states (83%) collected data on childhood immunizations. No more than half of the states collected data on other selected measures of access and quality, but a substantial number planned to collect such data in 1997. While at most 37% of states were providing comparative data to health plans, up to 80% were planning to provide such information in 1997. Similarly, while at most 10% of states provided beneficiaries with such information, up to 38% planned to do so in 1997. The breadth of contracting requirements designed to assure quality varied substantially across states. CONCLUSIONS: State Medicaid agencies have already begun adapting to their new roles as purchasers of health care. Continued monitoring is essential to ensure that state agencies implement planned programs and that quality of care for Medicaid enrollees is preserved or improved.

Mitogen-activated protein kinase activation: an alternate signaling pathway for sustained vascular smooth muscle contraction.
PURPOSE: The vascular smooth muscle determines the dynamic caliber of the blood vessel and hence is the final effector cell in modulating vasomotor tone. Although considerable information is available regarding the physiologic agonists that induce contraction, less is known about the cellular signaling events that lead to long-lasting contractions or vasospasm. We examined the hypothesis that activation of mitogen-activated protein (MAP) kinase may be associated with sustained smooth muscle contractions. METHODS: Physiologic contractile responses were determined in intact bovine carotid artery smooth muscles in a muscle bath. Corresponding signaling events were determined with immunoblots using antiphosphotyrosine antibodies or immunoprecipitation of whole-cell phosphorylated strips of muscle. RESULTS: The tyrosine kinase inhibitor, genestein, significantly inhibited the magnitude of contractions induced by phorbol ester, endothelin, angiotensin, and serotonin. In addition, genestein inhibited the sustained phase of contractions induced by serotonin. Serotonin-induced vascular smooth muscle contractions were temporally associated with an increase in the phosphorylation of MAP kinase. CONCLUSIONS: These data suggest that the activation of MAP kinase is associated with sustained vascular smooth muscle contractions. Pharmacologic manipulation of MAP kinase activation may lead to new approaches to treat pathologic circumstances of increased vasomotor tone such as vasospasm.

Attitudes about treatment of coronary heart disease among women and men presenting for exercise testing.
To assess attitudes that could contribute to gender differences in the use of coronary procedures, we surveyed 322 patients presenting for exercise testing at a major teaching hospital. Adjusting for sociodemographic and clinical factors, women and men did not differ significantly in their willingness to seek a second opinion, reduce physical activity, or take drugs to avoid major cardiac surgery, but men were more likely than women to describe themselves as risk takers on a three-item personality measure (adjusted odds ratio 2.5; 95% confidence interval 1.4-4.6). Patients' attitudes about risk should be explored further in studies of gender differences in the use of coronary procedures.

The Boston AIDS Survival Score (BASS): a multidimensional AIDS severity instrument.
OBJECTIVES: This study developed a new acquired immunodeficiency syndrome (AIDS) severity system by including diagnostic, physiological, functional, and sociodemographic factors predictive of survival. METHODS: Three-hundred five persons with AIDS in Boston were interviewed; their medical records were reviewed and vital status ascertained. RESULTS: Overall median (+/- SD) survival for the cohort from the first interview until death was 560 +/- 14.4 days. The best model for predicting survival, the Boston AIDS Survival Score, included the Justice score (stage 2 relative hazard [RH] = 1.25, 95% confidence interval [CI] = 0.80, 1.96; stage 3 RH = 1.76, 95% CI = 1.15, 2.70), a newly developed opportunistic disease score (Boston Opportunistic Disease Survival Score; stage 2 RH = 1.35, 95% CI = 0.90, 2.02; stage 3 RH = 2.10, 95% CI = 1.38, 3.18), and measures of activities of daily living (any intermediate limitations, RH = 1.84, 95% CI = 1.05, 3.21; any basic limitations, RH = 2.60, 95% CI = 1.44, 4.69). This model had substantially greater predictive power (R2 = .17, C statistic = .68) than the Justice score alone (R2 = .09, C statistic = .61). CONCLUSIONS: Incorporating data on clinically important events and functional status into a physiologically based system can improve the prediction of survival with AIDS.

Influence of cardiac-surgery performance reports on referral practices and access to care. A survey of cardiovascular specialists.
BACKGROUND: Reports on the comparative performance of physicians are becoming increasingly common. Little is known, however, about the credibility of these reports with target audiences or their influence on the delivery of medical services. METHODS: Since 1992, Pennsylvania has published the Consumer Guide to Coronary Artery Bypass Graft Surgery, which lists annual risk-adjusted mortality rates for all hospitals and surgeons providing such surgery in the state. In 1995, we surveyed a randomly selected sample of 50 percent of Pennsylvania cardiologists and cardiac surgeons to find out whether they were aware of the guide and, if so, to determine their views on its usefulness, limitations, and influence on providers. RESULTS: Eighty-two percent of the cardiologists and all the cardiac surgeons were aware of the guide. Only 10 percent of these respondents reported that its mortality rates were "very important" in assessing the performance of a cardiothoracic surgeon. Less than 10 percent reported discussing the guide with more than 10 percent of their patients who were candidates for a coronary-artery bypass graft (CABG). Eighty-seven percent of the cardiologists reported that the guide had a minimal influence or none on their referral recommendations. For both groups, the most important limitations of the guide were the absence of indicators of quality other than mortality (cited by 78 percent), inadequate risk adjustment (79 percent), and the unreliability of data provided by hospitals and surgeons (53 percent). Fifty-nine percent of the cardiologists reported increased difficulty in finding surgeons willing to perform CABG surgery in severely ill patients who required it, and 63 percent of the cardiac surgeons reported that they were less willing to operate on such patients. CONCLUSIONS: The Consumer Guide to Coronary Artery Bypass Graft Surgery has limited credibility among cardiovascular specialists. It has little influence on referral recommendations and may introduce a barrier to care for severely ill patients. If publicly released performance reports are intended to guide the choice of providers without impeding access to medical care, a collaborative process involving physicians may enhance the credibility and usefulness of the reports.

Cholesterol-reduction intervention study (CRIS): a randomized trial to assess effectiveness and costs in clinical practice.
BACKGROUND: The 1988 US National Cholesterol Education Program Expert Panel Report recommended initial treatment with niacin or bile acid sequestrants, followed by other agents if needed, to lower low-density lipoprotein cholesterol (LDL-C) levels in hypercholesterolemic patients who require drug therapy. It is unknown how the effectiveness and costs of such an approach ("stepped care") compare in typical clinical practice to those of initial therapy with lovastatin. PATIENTS AND METHODS: We randomly assigned 612 patients, aged 20 to 70 years, who met 1988 National Cholesterol Education Program guidelines for drug treatment of elevated LDL-C level and had not previously used cholesterol-lowering medication, to either a stepped-care regimen or initial therapy with lovastatin (both n=306). The study, conducted at Southern California Kaiser Permanente, was designed to approximate typical practice: provider compliance with treatment plans was encouraged but not enforced, and patients paid for medication as they customarily would. RESULTS: At 1 year, the decline in mean LDL-C level was significantly greater among patients assigned to initial treatment with lovastatin (22% vs 15% for stepped care; P<.001), as was the number who attained goal LDL-C level (</= 4.14 mmol/L [</= 160 mg/dL], or </= 3.36 mmol/L [</= 130 mg/dL] if coronary heart disease or two or more risk factors were present) (40% vs 24%; P<.001). The increase in mean high-density lipoprotein cholesterol levels was significantly greater in the stepped-care group, however (8% vs 1% for lovastatin; P<.001). Patients who were randomized to stepped care were more likely to report substantial bother caused by side effects (30% vs 16% for lovastatin; P<.001) and discontinuation of therapy at 1 year (28% vs 18%, respectively; P<.01). Costs of care were $333 higher per patient in the lovastatin group ($786 vs $453; P<.001). CONCLUSIONS: A stepped-care regimen beginning with niacin is less costly than initial therapy with lovastatin, but also less effective in lowering LDL-C level. While it is more effective in increasing high-density lipoprotein cholesterol levels, the tolerability of such a regimen may be a problem.

The influence of health-related quality of life and social characteristics on hospital use by patients with AIDS in the Boston Health Study.
OBJECTIVES: The authors examine whether health-related quality of life (HRQL) and social factors were independent predictors of future hospital use for persons with acquired immunodeficiency syndrome (AIDS). METHODS: A panel of 305 patients with AIDS treated at three provider settings in the Boston, Massachusetts area were enrolled during 1990 and 1991. Data were collected at baseline study enrollment and again 4 months later. Patient interviews, hospital bills, and medical charts were used to measure hospital use (admissions and days during the 4 months after enrollment), sociodemographic characteristics (age, gender, race, education, insurance, homelessness, alcohol use, and AIDS risk factors), disease burden (patient severity and a three-level opportunistic diseases and complications score), HRQL (patient-reported symptoms, activities of daily living, neuropsychological status, and global health assessment), system of care, and use of prophylactic drugs. Logistic regression was used to estimate the odds of admission. Total days of hospital care by patients with at least one admission were analyzed using multiple linear regression. Clinical models of hospital use were developed first from the variables measuring disease burden and system of care. Models estimating the associations between hospital use and all other predictor variables measured at baseline then were estimated using stepwise techniques, controlling for variables in the core model. RESULTS: Patients were more likely than their reference groups to be hospitalized if they had serious opportunistic diseases (adjusted odds ratio [OR] = 2.7), had poorer neuropsychological status (OR = 1.9), were non-white (OR = 2.0), or were homeless (OR = 3.3) (all P < or = 0.05). Activities of daily living were associated moderately (OR = 1.3; P = 0.07). Only system of care and neuropsychological status predicted total hospital days. CONCLUSIONS: The results indicate that future hospital use by persons with AIDS may be influenced by social and other health-related factors in addition to the more clinically related characteristics that are recorded in a medical chart. It therefore may be appropriate to assess these factors when considering options for intervention or when comparing patterns of use among patient groups or settings.
