Primary care outcomes in patients treated by nurse practitioners or physicians: a randomized trial.

CONTEXT: Studies have suggested that the quality of primary care delivered by nurse practitioners is equal to that of physicians. However, these studies did not measure nurse practitioner practices that had the same degree of independence as the comparison physician practices, nor did previous studies provide direct comparison of outcomes for patients with nurse practitioner or physician providers. OBJECTIVE: To compare outcomes for patients randomly assigned to nurse practitioners or physicians for primary care follow-up and ongoing care after an emergency department or urgent care visit. DESIGN: Randomized trial conducted between August 1995 and October 1997, with patient interviews at 6 months after initial appointment and health services utilization data recorded at 6 months and 1 year after initial appointment. SETTING: Four community-based primary care clinics (17 physicians) and 1 primary care clinic (7 nurse practitioners) at an urban academic medical center. PATIENTS: Of 3397 adults originally screened, 1316 patients (mean age, 45.9 years; 76.8% female; 90.3% Hispanic) who had no regular source of care and kept their initial primary care appointment were enrolled and randomized with either a nurse practitioner (n = 806) or physician (n = 510). MAIN OUTCOME MEASURES: Patient satisfaction after initial appointment (based on 15-item questionnaire); health status (Medical Outcomes Study Short-Form 36), satisfaction, and physiologic test results 6 months later; and service utilization (obtained from computer records) for 1 year after initial appointment, compared by type of provider. RESULTS: No significant differences were found in patients' health status (nurse practitioners vs physicians) at 6 months (P = .92). Physiologic test results for patients with diabetes (P = .82) or asthma (P = .77) were not different. For patients with hypertension, the diastolic value was statistically significantly lower for nurse practitioner patients (82 vs 85 mm Hg; P = .04). No significant differences were found in health services utilization after either 6 months or 1 year. There were no differences in satisfaction ratings following the initial appointment (P = .88 for overall satisfaction). Satisfaction ratings at 6 months differed for 1 of 4 dimensions measured (provider attributes), with physicians rated higher (4.2 vs 4.1 on a scale where 5 = excellent; P = .05). CONCLUSIONS: In an ambulatory care situation in which patients were randomly assigned to either nurse practitioners or physicians, and where nurse practitioners had the same authority, responsibilities, productivity and administrative requirements, and patient population as primary care physicians, patients' outcomes were comparable.

Information and its impact on satisfaction among surgical patients.

This study investigates the association between patient characteristics, reported problems with obtaining information and global evaluations of care among surgical patients. Using data from a large scale study of hospital care, a factor analysis of 30 information-relevant items was conducted with data from a sample of 3602 surgical patients; and correlation and multiple regression analyses were conducted to identify the relationships among information, patient characteristics and global evaluations of care. Path analysis was also used to determine the extent to which perceived control mediates the information evaluation relationship. Four information factors were identified: surgical information, recovery information, general information and sensory information, and each was significantly related to global evaluations. Desire for involvement interacted with information received in determining patients' evaluations; and partial support was found for perceived control as a mediator of the information evaluation link. The data indicate that the relationship between information and evaluations of quality is generalizable across patients, conditions and hospitals; and should be defined more broadly to include that which is given by a variety of providers. to family, and about medications and home recovery. Desire for involvement and perceived control must also be considered in understanding the value and impact of information.

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.

Is the professional satisfaction of general internists associated with patient satisfaction?

BACKGROUND: The growth of managed care has raised a number of concerns about patient and physician satisfaction. An association between physicians' professional satisfaction and the satisfaction of their patients could suggest new types of organizational interventions to improve the satisfaction of both. OBJECTIVE: To examine the relation between the satisfaction of general internists and their patients. DESIGN: Cross-sectional surveys of patients and physicians. SETTING: Eleven academically affiliated general internal medicine practices in the greater-Boston area. PARTICIPANTS: A random sample of English-speaking and Spanish-speaking patients (n = 2,620) with at least one visit to their physician (n = 166) during the preceding year. MEASUREMENTS: Patients' overall satisfaction with their health care, and their satisfaction with their most recent physician visit. MAIN RESULTS: After adjustment, the patients of physicians who rated themselves to be very or extremely satisfied with their work had higher scores for overall satisfaction with their health care (regression coefficient 2.10; 95% confidence interval 0.73-3.48), and for satisfaction with their most recent physician visit (regression coefficient 1.23; 95% confidence interval 0.26-2.21). In addition, younger patients, those with better overall health status, and those cared for by a physician who worked part-time were significantly more likely to report better satisfaction with both measures. Minority patients and those with managed care insurance also reported lower overall satisfaction. CONCLUSIONS: The patients of physicians who have higher professional satisfaction may themselves be more satisfied with their care. Further research will need to consider factors that may mediate the relation between patient and physician satisfaction.

Dimensions of consumer-assessed quality of Medicare managed-care health plans.

OBJECTIVES: We investigated relationships at the health-plan level among member ratings of and reports on plans in the Consumer Assessment of Health Plans Survey (CAHPS). We sought a more parsimonious description of the reports that can be used in analyses of the distribution and correlates of consumer-assessed quality. SUBJECTS: There were 89,419 Medicare beneficiaries enrolled in 212 Medicare managed-care health plans who responded to CAHPS in 1998. MEASURES: There were 39 survey items measuring consumer ratings of and reports on care. METHODS: We adjusted correlations for sampling variability in the plan means and performed a principal factor analysis of the report items with oblique rotation. We grouped items that loaded heavily on the different factors, formed composites, and regressed rating items on the report composites. RESULTS: Four factors explained 75% of the variance in the reports. The corresponding groups of items were concerned with the following subjects: (1) interactions around delivery of care in the doctor's office; (2) customer service from the plan; (3) access to medical services provided by the plan, such as specialist care, equipment, therapy, or drugs; and (4) advice on health-promoting activities. Corrected Cronbach alpha for composites were 0.97, 0.93, 0.86, and 0.60. The "delivery" composite was strongly predictive of overall ratings of care, doctor, and specialist; the "customer" composite was strongly predictive of overall ratings of the plan. CONCLUSIONS: CAHPS distinguishes among dimensions of between-plan variability of consumer-assessed quality. Different global ratings are related to distinct groups of consumer reports on their experiences.

Impact of sociodemographic case mix on the HEDIS measures of health plan quality.

BACKGROUND: The widely used Health Plan Employer Data and Information Set (HEDIS) measures may be affected by differences among plans in sociodemographic characteristics of members. OBJECTIVE: The objective of this study was to estimate effects of geographically linked patient sociodemographic characteristics on differential performance within and among plans on HEDIS measures. RESEARCH DESIGN: Using logistic regression, we modeled associations between age, sex, and residential area characteristics of health plan members and results on HEDIS measures. We then calculated the impact of adjusting for these associations on plan-level measures. SUBJECTS: This study included 92,232 commercially insured members with individual-level HEDIS data and an additional 20,615 members whose geographic distribution was provided. MEASURES: This study used 7 measures of screening and preventive services. RESULTS: Performance was negatively associated with percent receiving public assistance in the local area (6 of 7 measures), percent black (5 measures), and percent Hispanic (2 measures) and positively associated with percent college educated (6 measures), percent urban (2 measures), and percent Asian (1 measure) after controlling for plan and product type. These effects were generally consistent across plans. When measures were adjusted for these characteristics, rates for most plans changed by less than 5 percentage points. The largest change in the difference between plans ranged from 1.5% for retinal exams for people with diabetes to 20.2% for immunization of adolescents. CONCLUSIONS: Performance on quality indicators for individual members is associated with sociodemographic context. Adjustment has little impact on the measured performance of most plans but a substantial impact on a few. Further study with more plans is required to determine the appropriateness and feasibility of adjustment.

Does the effect of respondent characteristics on consumer assessments vary across health plans?

Responses to the Consumer Assessments of Health Plans Survey (CAHPS) are related to respondent characteristics. CAHPS procedures include casemix adjustment to remove effects of difference in respondent characteristics on comparative plan ratings, under the assumption that casemix coefficients are homogeneous across plans. The authors analyzed data from the Washington state CAHPS demonstration, fitting hierarchical models in which coefficients of casemix variables and intercepts could vary by plan. They estimated the impact of variability in casemix coefficients on plan adjustments and also assessed the implications for differential effects of individual characteristics at different plans. Estimated between-plan variability of coefficients was small, but the data are consistent with substantially larger variability. The potential impact of this variability on adjustments for plans was small relative to the magnitude of the adjustments. Comparisons between plans for individuals, however, could be affected substantially. This methodology could be useful wherever casemix adjustment is applied.

How consumer assessments of managed care vary within and among markets.

This study investigated the extent to which the Consumer Assessments of Health Plans Survey (CAHPS) distinguishes performance of Medicare managed care (MMC) health plans. Results indicate that CAHPS ratings and report composites distinguish among plans both nationally and within markets. Global ratings of a health plan and reports on customer services varied strongly at the individual plan level, with smaller effects seen at regional and Metropolitan Statistical Area (MSA) levels. Ratings of doctors and health care, and reports on experiences in the doctor's office varied more among regions and among MSAs than among plans within the same MSA. These patterns are consonant with our hypotheses about the determinants of these ratings: customer service is a distinct plan function, but medical services are provided by networks that often overlap for plans in the same area. We conclude that the CAHPS-MMC survey can inform consumers choosing among plans as well as policymakers and researchers.

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.

Sample allocation for overlapping domains in a physician survey with a limited population.

We consider an analytic survey in which each survey unit can respond with respect to one or more domains to which it belongs. In this situation, the optimal sample allocation is constrained by the number of available units in each stratum defined by a set of domains. We present optimal sample allocation rules for this situation, and other rules that apply when there are additional constraints on sample sizes or variances by domain. We apply these rules to our motivating example, the design of a survey of physicians on their experiences with health plans, in which each physician can only be asked about her experience with one plan regardless of her number of affiliations.

Use of hormone replacement therapy by postmenopausal women in the United States.

BACKGROUND: The benefits and risks of hormone replacement therapy (HRT) in postmenopausal women are not fully defined, and individual characteristics and preferences may influence decisions to use this therapy. Previous studies of postmenopausal women who use HRT have been conducted in local or highly selected cohorts or have not focused on current use. OBJECTIVE: To examine sociodemographic, clinical, and psychological factors associated with current use of HRT in a national population-based cohort. DESIGN: Random-digit telephone survey. SETTING: Probability sample of U.S. households with a telephone. PARTICIPANTS: 495 postmenopausal women 50 to 74 years of age in 1995. MEASUREMENTS: Current use of HRT. RESULTS: Current use of HRT was reported by 37.6% of women (58.7% of those who underwent hysterectomy and 19.6% of those who did not undergo hysterectomy; P = 0.001). In multivariable analyses, use of HRT was more common among women in the South (adjusted odds ratio, 2.67 [95% CI, 1.08 to 6.59]) and West (odds ratio, 2.76 [CI, 1.01 to 7.53]) than the Northeast. Use was more common among college graduates (odds ratio, 3.72 [CI, 1.29 to 10.71]) and less common among women with diabetes mellitus (odds ratio, 0.17 [CI, 0.05 to 0.51]). Other cardiac risk factors and most psychological characteristics were not associated with HRT use. CONCLUSIONS: Sociodemographic factors, such as region and education, may be more strongly associated with use of HRT than clinical factors, such as risk for cardiovascular disease. Future efforts should focus on understanding sociodemographic variations, defining which women are most likely to benefit, and targeting therapy to them.

Perceived risks of heart disease and cancer among cigarette smokers.

CONTEXT: Cigarette smoking causes more preventable deaths from cardiovascular disease and cancer than any other modifiable risk factor, but smokers may discount the increased personal risk they face from continued smoking. OBJECTIVE: To assess smokers' perceptions of their risks of heart disease and cancer. DESIGN AND SETTING: Telephone and self-administered survey in 1995 of a probability sample of US households with telephones. PARTICIPANTS: A total of 3031 adults aged 25 to 74 years, including 737 current smokers (24.3%). MAIN OUTCOME MEASURES: Respondents with no history of myocardial infarction (MI) (96.2 %) or cancer (92.9%) assessed their risk of these conditions relative to other people of the same age and sex. Among current smokers, perceived risks were analyzed by demographic and clinical factors using logistic regression. RESULTS: Only 29% and 40% of current smokers believed they have a higher-than-average risk of MI or cancer, respectively, and only 39% and 49% of heavy smokers (> or =40 cigarettes per day) acknowledged these risks. Even among smokers with hypertension, angina, or a family history of MI, 48%, 49%, and 39%, respectively, perceived their risk of MI as higher than average. In multivariate analyses, older (> or =65 years), less educated (< high school graduate), and light smokers (1-19 cigarettes per day) were less likely than younger, more educated, and heavy smokers to perceive an increased personal risk of MI or cancer. CONCLUSIONS: Most smokers do not view themselves at increased risk of heart disease or cancer. As part of multifaceted approaches to smoking cessation, physicians and public health professionals should identify and educate smokers who are not aware of smoking-related health risks.

Quality of care at a children's hospital: the parent's perspective.

OBJECTIVES: To develop a measure of parental perceptions of pediatric inpatient quality of care, to identify processes of care that influence these perceptions, and to describe these perceptions of care. DESIGN: An interdisciplinary team modified an existing measure of inpatient care for adults using focus groups and expert review. The resulting survey was administered by telephone. SETTING: Tertiary care pediatric hospital. PATIENTS: Trained telephone interviewers obtained reports from parents of children discharged from the hospital during specified months. This report is based on the answers to 122 questions provided by 3622 (77%) of 4724 parents who responded when surveyed from 1991 through 1995. MAIN OUTCOME MEASURES: Parents provided reports about specific clinical experiences, overall ratings of care, and patient demographic and illness characteristics 2 weeks after patient discharge from the hospital. The analysis classified reports about pediatric care as either problems or not problems. Problems in different areas of care were averaged to create scores for the dimensions. RESULTS: Parents most often noted problems related to hospital discharge planning (18%) and pain management (18%) and less often reported problems concerning communication about surgery (10%) or transmission of information to children (6%). Problems in communication between clinicians and parents correlated most strongly with overall quality ratings by parents (r=0.59). Parents' specific reports of problems with care accounted for 42% of the variation in their overall assessments of the inpatient care experience. CONCLUSIONS: Parental assessment of inpatient pediatric care rests heavily on the quality of communication between the clinician and parent. Specific processes of care strongly influence overall assessments. Such reports could be used to focus the quality-improvement activities of hospitals and increase the accountability of providers of care to children and families.

Benchmarking and quality improvement: the Harvard Emergency Department Quality Study.

PURPOSE: To determine whether feedback of comparative information was associated with improvement in medical record and patient-based measures of quality in emergency departments. SUBJECTS AND METHODS: During 1-month study periods in 1993 and 1995, all medical records for patients who presented to five Harvard teaching hospital emergency departments with one of six selected chief complaints (abdominal pain, shortness of breath, chest pain, hand laceration, head trauma, or vaginal bleeding) were reviewed for the percent compliance with process-of-care guidelines. Patient-reported problems and patient ratings of satisfaction with emergency department care were collected from eligible patients using patient questionnaires. After reviewing benchmark information, emergency department directors designed quality improvement interventions to improve compliance with the process-of-care guidelines and improve patient-reported quality measures. RESULTS: In the preintervention period, 4,876 medical records were reviewed (99% of those eligible), 2,327 patients completed on-site questionnaires (84% of those eligible), and 1,386 patients completed 10-day follow-up questionnaires (80% of a random sample of eligible participants). In the postintervention period, 6,005 medical records were reviewed (99% of those eligible), 2,899 patients completed on-site questionnaires (84% of those eligible), and 2,326 patients completed 10-day follow-up questionnaires (80% of all baseline participants). In multivariate analyses, adjusting for age, urgency, chief complaint, and site, compliance with process-of-care guidelines increased from 55.9% (preintervention) to 60.4% (postintervention, P = 0.0001). We also found a 4% decrease (from 24% to 20%) in the rate of patient-reported problems with emergency department care (P = 0.0001). There were no significant improvements in patient ratings of satisfaction. CONCLUSION: Feedback of benchmark information and subsequent quality improvement efforts led to small, although significant, improvement in compliance with process-of-care guidelines and patient-reported measures of quality. The measures that relied on patient reports of problems with care, rather than patient ratings of satisfaction with care, seemed to be more responsive to change. These results support the value of benchmarking and collaboration.

Carepartner experiences with hospital care.

OBJECTIVES: Family members and other "carepartners" often play an important role in the care and support of patients during and after hospitalization, yet little is known about how they assess their hospital experience or the factors that may influence their perceptions. METHODS: A nationwide telephone survey of 1,800 recently discharged patients and their carepartners about their hospital experience was conducted. Carepartner responses in six domains of care were summarized, and multivariable regression analysis was used to detect independent predictors of more frequent problem reports by carepartners. RESULTS: Carepartners reported problems most frequently in the domains of emotional support (23.9%), discharge planning (20.3%), and family participation (17.6%). Independent predictors of more frequent carepartner problem reports included poor subjective patient health status, emergency hospitalization, nonsurgical admission, carepartner income less than $7,500/year, younger carepartner age, noninvolvement of the patient's regular doctor, less frequent carepartner visits during the hospitalization, and less time spent with the patient after discharge. CONCLUSIONS: Better awareness of the problems carepartners experience and attention to improving quality in these areas may facilitate family involvement in patient care and enhance carepartner and patient satisfaction.

Psychometric properties of the CAHPS 1.0 survey measures. Consumer Assessment of Health Plans Study.

OBJECTIVES: Consumer surveys are being used increasingly to assess the quality of care provided by health plans, physician groups, and clinicians. The purpose of the Consumer Assessment of Health Plans Study (CAHPS) is to develop an integrated and standardized set of surveys designed to collect reliable and valid information about health plan performance from consumers. This article reports psychometric results for the CAHPS 1.0 survey items in samples of individuals with Medicaid or private health insurance coverage. METHODS: Reliability estimates for CAHPS 1.0 measures were estimated in a sample of 5,878 persons on Medicaid and 11,393 persons with private health insurance. Correlations of the CAHPS global rating of the health plan with willingness to recommend the plan and intention to re-enroll were estimated in a sample of 313 persons on Medicaid. The association of the rating of the health plan with ratings using a 5-point Excellent-to-Poor response scale also was investigated in the latter sample and in a sample of 539 persons with private health insurance. RESULTS: The CAHPS measures appeared to have good reliability, particularly at the health-plan level. Responses from 300 consumers per health plan tend to yield estimates that are reliable enough for health plan comparisons, especially among the privately insured. The global health plan rating was significantly correlated with consumers' willingness to recommend the plan to family and friends and to their intention to re-enroll in the plan if given a choice. CONCLUSIONS: The CAHPS 1.0 survey instrument appears to have excellent psychometric properties.
