Developing an AHC-MCO alliance for research and care.

Academic health centers (AHCs) and managed care organizations (MCOs) appear to be on a collision course. Is it possible to develop a partnership to enable both parties to achieve their respective goals and objectives? The Kimmel Cancer Center of Thomas Jefferson University and AEtna US Healthcare, one of the nation's largest MCOs, have developed an alliance designed to generate cancer prevention and control research. This arrangement engages the participants in a collaborative effort that is aimed at creating new knowledge that can be used to enhance the provision of health care to a defined population.

Issues of cost and quality: barriers to an informed debate.

Debates over health reform in the United States are hampered by a poorly informed public and misunderstandings about the concepts of quality, cost containment and their relationship to each other. This paper explores the nature and persistence of barriers to an informed public discussion of reform proposals. Those barriers are: (1) multiple definitions of quality, cost and cost containment, (2) the impact of the media on those definitions, (3) a false assumption that cost containment automatically results in diminished quality, and (4) the perceived impact of managed care and for-profit health firms on that assumption. We suggest a framework for building the understanding and knowledge base necessary to a reform of the nation's health care system.

Centralization of histocompatibility laboratories: impact on organ allocation efficiency and outcomes of cadaveric renal transplantation.

This project was undertaken to determine whether centralization of histocompatibility laboratory services for renal transplants performed within eastern Pennsylvania could improve the efficiency of allograft allocation and short-term allograft function. A nonconcurrent cohort study was performed comparing renal allografts transplanted between September 15, 1993, and September 14, 1994, to those transplanted between September 15, 1994, and September 14, 1995. All allografts were procured and allocated by the Delaware Valley Transplant Program, the organ procurement agency in eastern Pennsylvania. Cold preservation time and delayed allograft function were used to measure efficiency of allograft allocation and short term allograft function, respectively. The mean cold preservation time was reduced from 25.08 hours to 20.68 hours (P < 0.001). The percentage of delayed allograft function was 19.9 and 17.4 for the pre- and postcentralization groups, respectively (P = 0.5). Therefore, centralization of histocompatibility tissue typing was a regionally effective process intervention for reducing cold preservation time without adversely impacting short-term graft function. The magnitude of this reduction varied between individual centers. Further investigation is required to determine the effect on long-term allograft function and system wide costs.

Clinical decision making--what every non-clinician manager should know but was never taught.

The management of a health care system requires making decisions and establishing policies that can affect the process of patient care. Clinicians often complain that these decisions and policies are made by people without clinical training. Clinical knowledge is not a prerequisite for a career in health policy or management. Even graduates of accredited health administration programs are not required to understand the process of clinical decision making or the nature of medical practice. Much of the health services literature advocates a shared decision-making model for clinicians and managers. However, most of the literature focuses on how to involve physicians in management decision making; almost none discusses management involvement in clinical decisions. This paper briefly examines how non-clinician managers can support the clinical decision-making process and then specifies the knowledge and skills required for them to play this role.

Emerging opportunities for educational partnerships between managed care organizations and academic health centers.

Medical schools, teaching hospitals, and managed care organizations have a vested interest in shaping the knowledge, skills, and attitudes of the next generation of physicians who must adapt to significant changes in the financing and delivery of health care. This article summarizes the rationale for educational partnerships between managed care and academic medicine based on a review of three decades of well-documented experimentation in the literature. Discussed are some of the most important characteristics of the successful partnerships being forged in the current healthcare environment based on new kinds of relationships between faculty and non-university clinician educators. What had been referred to in previous decades as the "teaching-HMO" is now being complemented by community-based links between academic health centers and managed care plans. Several public and private sources have been generous in providing venture capital to support many of these innovations. However, their continued operation will depend on models for health care networks that can identify and manage the revenue and costs associated with the missions of education, clinical services, and research.

Do cardiologists do it better?

Pressure to lower the cost of health care delivery has fostered widespread efforts to limit patients' access to specialists such as cardiologists. However, there is concern that diminished specialist involvement may lead to poorer patient outcomes for specific clinical conditions. As part of a state-sponsored effort to improve the quality of health care in Pennsylvania, the Pennsylvania Health Care Cost Containment Council gathered clinical and administrative data on all 40,684 hospital admissions for acute myocardial infarction (AMI) in that state in 1993. They prepared a detailed public report that included risk-adjusted in-hospital mortality and length of hospital stay by physician group, by hospital and by region. These data demonstrate that patients cared for by cardiologists, as a group, had a lower risk-adjusted mortality than patients cared for by either internists (risk ratio 1.26, 95% confidence interval 1.17 to 1.35) or family practitioners (risk ratio 1.29, 95% confidence interval 1.18 to 1.40). The patients of cardiologists also had a shorter length of stay than the other two groups. These data suggest that there is enhanced value in the care provided by cardiologists for patients with AMI and call into question the growing trend toward reliance on generalists instead of specialists.

Estimation of the cost savings resulting from the use of ursodiol for the prevention of gallstones in obese patients undergoing rapid weight reduction.

BACKGROUND: Morbidly obese patients enrolled in a rapid weight reduction program are at a high risk of developing gallstones. Two multicenter, placebo-controlled, randomized, double-blind trials have demonstrated that the prophylactic use of ursodiol in males and females 18 to 70 years of age is effective for the prevention of gallstone formation in this patient population. This study examines the cost consequences associated with the prophylactic use of ursodiol. METHODS: A medical decision analysis model for the prophylactic administration of ursodiol in morbidly obese patients undergoing rapid weight reduction by either gastric bypass surgery or very-low-calorie-diet, was developed through the use of data from two clinical trials and review of the related literature. The expert opinion of clinicians from the fields of internal medicine, gastroenterology and surgery were solicited. Financial data for the charges associated with cholecystectomies, physician fees and ursodiol were obtained from current financial databases. RESULTS: The model demonstrates that the prophylactic administration of ursodiol, in morbidly obese patients undergoing rapid weight reduction, results in cost savings. Sensitivity analysis was performed to illustrate that the cost savings achieved by the prophylactic use of ursodiol were valid over a realistic range of charges and assumptions. CONCLUSION: The decision model may allow health care decision makers to apply their own data to the model to determine the cost savings obtainable through the prophylactic use of ursodiol in patients undergoing rapid weight reduction.

Bridging the gap between managed care and academic medicine: an innovative fellowship.

Numerous challenges face academic medicine in the era of managed care. This environment is stimulating the development of innovative educational programs that can adapt to changes in the healthcare system. The U.S. Quality Algorithms Managed Care Fellowship at Jefferson Medical College is one response to these challenges. Two postresidency physicians are chosen as fellows each year. The 1-year curriculum is organized into four 3-month modules covering such subjects as biostatistics and epidemiology, medical informatics, the theory and practice of managed care, managed care finance, integrated healthcare systems, quality assessment and improvement, clinical parameters and guidelines, utilization management, and risk management. The fellowship may serve as a possible prototype for future post-graduate education.

Medical student education in managed care settings: beyond HMOs.

OBJECTIVE: To describe the educational experiences of students in managed care settings and to compare these with recommendations for preparing physicians to practice in managed care. DESIGN: We searched MEDLINE using the keywords "medical education," "managed care," "health maintenance organization," and others; we manually checked the reference lists of identified articles and reports from 1969 to 1996. Survey information was obtained from all US medical schools in 1995 and 1996. Site visits were made to 6 managed care organizations selected according to size, geographic region, and involvement in education. MAIN OUTCOME MEASURES: The extent to which schools use managed care settings for clinical education, the types of settings used, and the kinds of educational programs experienced. RESULTS: In 1995 and 1996, an average of 16% of schools required all students to have clerkships or other clinical experiences in a group/staff model HMO, and some students from another 46% of schools spent time in an HMO for clerkships or physical diagnosis/introduction to clinical medicine courses. About 85% of schools potentially exposed students to other types of managed care during 1 or more required clinical experiences in ambulatory, community-based settings. The learning objectives of these experiences did not explicitly address features unique to managed care such as cost containment and disease prevention. CONCLUSION: The selection of managed care settings for undergraduate education is based on general clinical objectives rather than explicit goals tied to managed care. Whether these experiences in managed care settings help students to develop competencies for future practice in a managed care environment has not been demonstrated. While the feasibility of medical education in nonprofit group/staff model HMOs is well documented, it is not certain whether these models can be adapted to for-profit managed care settings.

Managed care: past, present, and future.

The authors have examined managed care from several perspectives in this article. A look at the origins of managed care provided a historical perspective. The current state of managed care and its issues were presented. Finally, the authors speculated what the future may bring in terms of both continued current trends and significant changes in managed care. The authors hope that this presentation provides some insight to the practicing physician on how to work in a world with managed care and what the future may bring. Managed care brings changes in the way physicians practice, but it also offers physicians many opportunities to improve the quality and cost-effectiveness of health care. Managed care is the wave of the present and of the future. It is the health care market's choice to address the challenges that health care faces in quality, cost-effectiveness, accountability, access, and choice. Although there are numerous proposed, alternative, and theoretic solutions, managed care has insurmountable momentum. It will be molding the shape of health care as society enters the twenty-first century.
