Do employees use report cards to assess health care provider systems?

OBJECTIVE: To investigate consumers' use of report cards that provide information on service quality and satisfaction at the provider group level. DATA SOURCES: In 1998 we conducted a telephone survey of randomly selected employees in firms aligned with the Buyers Health Care Action Group (BHCAG) in the Minneapolis-St. Paul market. STUDY DESIGN: Univariate probit models were used to determine report card utilization, perceived helpfulness of the report card, and ease of selecting a provider group. The characteristics used in the models included health status, age, gender, education, residency, job tenure, marital status, presence of dependent children, household income, and whether consumers changed provider groups. DATA COLLECTION: Our sample consists of survey responses from 996 single individuals (a response rate of 91 percent) and 913 families (a response rate of 96 percent). The survey was supplemented with data obtained directly from employers aligned with BHCAG. PRINCIPLE FINDINGS: Consumers who changed to a new provider group are more likely to use report card information and find it helpful, consumers employed in large firms are less likely to use the report card, and families who use information from their own health care experiences are less likely to find the report card helpful. In addition, individuals who changed to a new provider group are more likely to find the selection decision difficult. CONCLUSION: The findings show that health care consumers are using satisfaction and service-quality information provided by their employers.

Do consumers use information to choose a health-care provider system?

This study examines the use of information by employees in the Buyers Health Care Action Group, a purchasing coalition of large employers in Minneapolis. BHCAG employers contract directly with multiple health-care provider systems and attempt to inform employees about those choices. Shortly after the close of the 1998 open-enrollment period, a survey of 927 BHCAG employees with single-coverage health insurance was conducted. Seventy-six percent of the employees relied on information from their employer when selecting their current care system. Use of information from the employer was positively related to education and years of residence in the Twin Cities. Previous experience with doctors and hospitals in the care system also was a common information source. Older and low-income workers were more likely to use information from advertisements. The survey results suggest that employers can predict which information sources their employees will use.

The financial impact on community mental health centers of capitated contracts with Medicaid: the Utah Prepaid Mental Health Plan.

Under the Utah Prepaid Mental Health Plan, three of the eleven Community Mental Health Centers in Utah signed capitation contracts with the state Medicaid program. The capitated Centers initially accepted the risk for inpatient care, with the risk later being extended to also include outpatient services. This study contrasts the financial experiences of the capitated Centers and five noncontracting Centers. While various patterns of financial management are evident in the data, it appears that the decision to contract had, at worst, a neutral effect on overall financial performance. Managed care programs with different designs may have different results.

Performance failure of an evidence-based upper respiratory infection clinical guideline.

BACKGROUND: We evaluated an upper respiratory infection (URI) clinical guideline to determine if it would favorably affect the quality and cost of care in a health maintenance organization. METHODS: Patients with URI symptoms contacting 4 primary care practices before and after guideline implementation were compared to ascertain what proportion of all patients with respiratory symptoms were eligible for treatment in accordance with the URI guideline; what proportion of eligible patients were managed without an office visit; and what proportion of eligible patients were treated with antibiotics, before and after guideline implementation. RESULTS: A total of 3163 patients with respiratory symptoms were identified. Of these, 59% (n = 1880) had disqualifying symptoms or comorbid conditions for URI guideline care, and 28% (n = 1290) received disqualifying diagnoses on the day of first contact, leaving 13% (n = 408) who received a diagnosis of URI and were eligible for care in accordance with the guideline. Among this group of patients, the proportion who received guideline-recommended initial telephone care was 45% preguideline and 47% postguideline (chi2 = 0.40; P = .82). Likelihood of a subsequent office visit increased from pre- to postguideline (chi2 = 17.1; P <.01), although the majority of patients had no further diagnoses other than URI. Antibiotic use for the initial URI diagnosis declined from 24% preguideline to 16% postguideline (chi2 = 3.97; P = .046), but antibiotic use during 21-day follow-up did not change (F = 0.46, P = .66). The mean cost of initial care was $37.80 preguideline and $36.20 postguideline (P >.05). CONCLUSIONS: Only 13% of primary care patients with respiratory symptoms were eligible for URI guideline care. Among eligible patients, use of the guideline failed to decrease clinic visits, decrease antibiotic use during a 21-day period, or reduce cost of care to the health plan.

Potential effects of managed care organizations in rural communities: a framework.

This article has provided a conceptual framework regarding the implications of a growing MCO presence in rural areas. This framework addresses factors likely to influence the degree of MCO presence in any given rural community, as well as the possible effects of that presence on rural consumers, employers, providers, and the uninsured. These factors vary across communities and will result in variation in the nature and importance of MCOs among rural communities. The arguments and considerations presented are based on analysis of MCO, employer, and consumer behavior, informed by research findings relating to MCOs in urban areas. The issues discussed raise a number of questions that deserve to be addressed through empirical research focused specifically on rural populations. The appendix contains a summary list of these questions. The next article reviews the results of existing research studies as they bear on these research questions and other issues raised in this article.

Changes in the process of care for Medicaid patients with schizophrenia in Utah's Prepaid Mental Health Plan.

OBJECTIVE: Changes in the process of psychiatric care received by Medicaid beneficiaries with schizophrenia were examined after the introduction of capitated payments for enrollees of some community mental health centers (CMHCs) under the Utah Prepaid Mental Health Plan. METHODS: Data from the medical records of 200 patients receiving care in CMHCs participating in the prepaid plan were compared with data from the records of 200 patients in nonparticipating CMHCs, which remained in a fee-for-service reimbursement arrangement. Using the Process of Care Review Form, trained abstracters gathered data characterizing general patient management, social support, medication management, and medical management before implementation of the plan in 1990 and for three follow-up years. Using regression techniques, differences in the adjusted changes between third-year follow-up and baseline were examined by treatment site. RESULTS: By year 3 at the CMHCs participating in the plan, psychotherapy visits decreased, the probability of a patient's terminating treatment or being lost to follow-up increased, the probability of having a case manager increased, the probability of a crisis visit decreased (but still exceeded that at the nonplan sites), and the probability of treatment for a month or longer with a suboptimal dosage of antipsychotic medication increased. Only modest changes in the process of care were observed at the nonplan CMHCs. CONCLUSIONS: Change in the process of psychiatric care was more evident at the sites participating in the plan, where traditional therapeutic encounters were de-emphasized in response to capitation. The array of changes raises questions about the vigor of care provided to a highly vulnerable group of patients.

Rural radiology: who is producing images and who is reading them?

The purpose of this study is to identify the local availability and trends in local availability of imaging technology and interpretation services in rural hospitals in the northwestern United States during the period between 1991 to 1994. Another objective is to describe hospital and community factors associated with the diffusion of image production and interpretation services. The information for this study was gathered through telephone surveys of rural hospital administrators in eight northwestern states in 1991 and 1994. The availability of magnetic resonance imaging (MRI) equipment, computed tomography (CT) scanners, ultrasonography equipment, and dedicated mammography equipment increased between 1991 and 1994. The increases in MRI units were primarily in mobile equipment, while ultrasonography and mammography equipment increases were primarily fixed hospital-based units. In 1994, image interpretation in the rural hospitals was provided by both primary care and radiology physicians. Forty-six (11.5%) of the rural hospitals had no on-site radiology services and only 73 (18%) had daily radiology services. Between 1991 and 1994, 12 hospitals gained at least once-a-week radiology services, but 24 lost all radiology services. Teleradiology availability more than doubled during the three years. Radiology technology has diffused widely into rural communities in this region of the United States at differing rates for large and small hospitals. Radiologists are available to these hospitals only 46 percent of the days each year, with more days of availability in the larger hospitals and fewer days in the smaller hospitals. Teleradiology capability is increasing more rapidly in the larger hospitals that have radiologists more readily available.

Expenditures for mental health services in the Utah Prepaid Mental Health Plan.

This article examines the effect of a mental health carve-out, the Utah Prepaid Mental Health Plan (UPMHP), on expenditures for mental health treatment and utilization of mental health services for Medicaid beneficiaries from July 1991 through December 1994. Three Community Mental Health Centers (CMHCs) provided mental health services to Medicaid beneficiaries in their catchment areas in return for capitated payments. The analysis uses data from Medicaid claims as well as "shadow claims" for UPMHP contracting sites. The analysis is a pre/post comparison of expenditures and utilization rates, with a contemporaneous control group in the Utah catchment areas not in the UPMHP. The results indicate that the UPMHP reduced acute inpatient mental health expenditures and admissions for Medicaid beneficiaries during the first 2 1/2 years of the UPMHP. In contrast, the UPMHP had no statistically significant effect on outpatient mental health expenditures or visits. There was no significant effect of the UPMHP on overall mental health expenditures.

Mechanism of action and impact of a cystitis clinical practice guideline on outcomes and costs of care in an HMO.

BACKGROUND: A study was conducted in 1995 at five primary care clinics of a staff-model health maintenance organization in the Midwest to assess the impact of a cystitis clinical guideline and to help elucidate the guideline implementation process. METHODOLOGY: Two hundred one eligible women with uncomplicated cystitis were treated in a three-month period before the guideline, and 241 similar cases were treated in a three-month period after the guideline. Nursing supervisors and clinic managers at each clinic were interviewed about how the cystitis guideline was implemented at each clinic. RESULTS: Use of a recommended three-day antibiotic treatment increased from 28% to 52% of cases (chi-square = 25.01, p < 0.001). Use of urine cultures decreased from 70% to 37% of cases (chi-square = 48.19, p < 0.001). The proportion of eligible cystitis cases coordinated primarily by the nurse increased from 21% to 78% (chi-square = 142.93, p < 0.001). However, desired changes in use of antibiotics and urine cultures were limited to nurse-coordinated cases. There was no increase in hospital admissions, emergency room visits, repeat office visits (p > 0.05), or repeat antibiotic courses (p > 0.05) after cystitis guideline implementation. Cost of cystitis care delivered after guideline implementation was 35% lower than before guideline implementation. CONCLUSIONS: Use of the guideline was associated with desirable changes in antibiotic use, nurse coordination of care, costs of care, and comparable clinical outcomes. Clinics that used clinical systems and tools to support nurse-coordinated cystitis care had greater guideline adherence than clinics that did not support nurse-coordinated care.

Effect of mergers on health maintenance organization premiums.

This study estimated the effect of mergers on health maintenance organization (HMO) premiums, using data on all operational non-Medicaid HMOs in the United States from 1985 to 1993. Two critical issues were examined: whether HMO mergers increase or decrease premiums; and whether the effects of mergers differ according to the degree of competition among HMOs in local markets. The only significant merger effect was found in the most competitive markets, where premiums increased, but only for 1 year after the merger. Our research does not support the argument that consolidation of HMOs in local markets will benefit consumers through lower premiums.

Economic and organizational determinants of HMO mergers and failures.

This study analyzed data from all operational health maintenance organizations (HMOs) in the United States from 1986 through 1993. Eighty HMOs disappeared through mergers and 149 failed over that period. We estimated a multinomial logit model to predict whether an HMO would merge and survive, merge and disappear, or fail, relative to the probability of no event. We found that enrollment and profitability play a critical role in explaining HMO mergers and failures: large and profitable HMOs were more likely to merge and survive, but less likely to merge and disappear or fail. These results explain why HMO merger and failure rates fell after 1988, as most surviving HMOs became larger and more profitable. Among several market-area variables in the model, state anti-takeover regulations had a negative impact on mergers. Mergers were more likely in markets with more competing HMOs, but the overall market penetration of HMOs had no effect on mergers. This result may have important implications for the current debate over the future of the competitive health care strategy. If public policy successfully stimulates the development of large numbers of new HMOs, another wave of mergers and failures is likely to occur. But it appears that growth in overall HMO penetration will not lead inevitably to increased market concentration.

Mobile technology in rural hospitals: the case of the CT scanner.

OBJECTIVE: This study evaluates the relationship between hospital and regional characteristics and the prevalence of mobile computed tomography in rural hospitals. DATA SOURCES AND STUDY SETTING: Primary data were gathered from all rural hospitals in eight northwestern states (n = 471) in 1991. Secondary data sources include the AHA Annual Survey, the Area Resource File, and HCFA's PPS data sets for 1987-1990. STUDY DESIGN: Primary data are a single observation taken in the summer of 1991. Key hospital characteristics include patient volume, distance to the nearest referral center, distance to the nearest hospital, financial performance, and medical staff size. Key regional variables include beds per unit area, hospitals per unit area, and physician supply. DATA COLLECTION: A structured telephone interview was conducted with the hospital administrator at each hospital. For many hospitals, detailed information was gathered with additional calls to hospital personnel. PRINCIPAL FINDINGS: Where hospitals are closely spaced, mobile CT suppliers are more readily available, and hospitals are more likely to choose mobile CT than in areas where hospitals are farther apart. Hospitals may realize economies of scale and scope in their decisions about CT adoption. CONCLUSIONS: Transportation costs are an important determinant of hospital decisions about acquiring CT, but may be less important for higher-priced medical technologies. There is no support for the proposition that rural hospitals compete with referral centers for patients by purchasing technological equipment.
