RESUMEN
There is ample evidence that many clinical decisions made by physicians are inconsistent with current and generally accepted evidence. This leads to the underuse of some efficacious diagnostic, preventive or therapeutic services, and the overuse of others of marginal or no value to the patient. Evolving new payment and delivery models place greater emphasis on the provision of evidence-based services at the point of care. However, changing physician clinical behaviors is likely to be difficult and slow. Policy makers therefore need to design interventions that are most effective in promoting greater evidence-based care. To help identify modifiable factors that can influence clinical decisions at the point of care, we present a conceptual model and literature review of physician decision making. We describe the multitude of factors--drawn from different disciplines--that have been shown to influence physician point-of-care decisions. We present a conceptual framework for organizing these factors, dividing them into patient, physician, practice site, physician organization, network, market, and public policy influences. In doing so, we review some of the literature that speak to these factors. We then identify areas where additional research is especially needed, and discuss the challenges and opportunities for health services and policy researchers to gain a better understanding of these factors, particularly those that are potentially modifiable by policymakers and organizational leaders.

BACKGROUND: For decades, reformers argued that medical groups can efficiently provide high-quality care and a collegial professional environment. The growth of managed care and the movement to improve quality provide additional reasons for physicians to practice in groups, especially large groups. However, information is lacking on recent trends in group size and the benefits of and barriers to group practice. OBJECTIVES: To identify benefits of and barriers to large medical group practice, and to describe recent trends in group size. DESIGN, SETTING, AND PARTICIPANTS: Information on benefits and barriers was obtained from 195 interviews conducted during round 3 (2000-2001) of the Community Tracking Study with leaders of the largest groups, hospitals, and health insurance plans in 12 randomly selected metropolitan areas. Information on recent trends in group size was obtained from more than 6000 physicians in private practice in 48 randomly selected metropolitan areas via Community Tracking Study telephone surveys in 1997-1998, 1998-1999, and 2000-2001. MAIN OUTCOME MEASURES: Benefits of and barriers to large group practice, as perceived by interviewees, and changes in percentages of physicians in groups of varying sizes. RESULTS: Gaining negotiating leverage with health insurance plans was the most frequently cited benefit; it was cited 8 times more often than improving quality. Lack of physician cooperation, investment, and leadership were the most frequently cited barriers. Survey data indicate that 47% of private physicians work in practices of 1 or 2 physicians and 82% in practices of 9 or fewer, and that the percentage of physicians in groups of 20 or more did not increase between 1996 and 2001. CONCLUSIONS: Current payment methods reward gaining size to obtain negotiating leverage more than they reward quality. However, barriers to creating large medical groups are substantial, and most private physicians continue to practice in small groups, although the size of these groups is slowly increasing.

OBJECTIVE: To describe how hospitals' negotiating leverage with managed care plans changed from 1996 to 2001 and to identify factors that explain any changes. DATA SOURCES: Primary semistructured interviews, and secondary qualitative (e.g., newspaper articles) and quantitative (i.e., InterStudy, American Hospital Association) data. STUDY DESIGN: The Community Tracking Study site visits to a nationally representative sample of 12 communities with more than 200,000 people. These 12 markets have been studied since 1996 using a variety of primary and secondary data sources. DATA COLLECTION METHODS: Semistructured interviews were conducted with a purposive sample of individuals from hospitals, health plans, and knowledgeable market observers. Secondary quantitative data on the 12 markets was also obtained. PRINCIPAL FINDINGS: Our findings suggest that many hospitals' negotiating leverage significantly increased after years of decline. Today, many hospitals are viewed as having the greatest leverage in local markets. Changes in three areas--the policy and purchasing context, managed care plan market, and hospital market--appear to explain why hospitals' leverage increased, particularly over the last two years (2000-2001). CONCLUSIONS: Hospitals' increased negotiating leverage contributed to higher payment rates, which in turn are likely to increase managed care plan premiums. This trend raises challenging issues for policymakers, purchasers, plans, and consumers.

This article reviews the recent research, policy and conceptual literature on the effects of payment policy reforms on evidence-based clinical decision-making by physicians at the point-of-care. Payment reforms include recalibration of existing fee structures in fee-for-service, pay-for-quality, episode-based bundled payment and global payments. The advantages and disadvantages of these reforms are considered in terms of their effects on the use of evidence in clinical decisions made by physicians and their patients related to the diagnosis, testing, treatment and management of disease. The article concludes with a recommended pathway forward for improving current payment incentives to better support evidence-based decision-making.

This article develops a framework for understanding how financial and nonfinancial incentives can complicate point-of-care decision-making by physicians, leading to the overuse or underuse of healthcare services. By examining the types of decisions that clinicians and patients make at the point-of-care, the framework clarifies how incentives can distort physicians' decisions about testing, diagnosis and treatment, as well as efforts to enhance patient adherence. The analysis highlights contributing factors that promote and impede evidence-based decision-making, using examples from the 'Choosing Wisely' program. It concludes with a summary of how the existing fee-for-service payment system in the USA may contribute to the problems of over- and under-testing, diagnosis and treatment, highlighted through the efforts of Choosing Wisely.

OBJECTIVE: This article reports the experiences of health plans, providers, and consumers with California's mental health parity law and discusses implications for implementation of the 2008 federal parity law. METHODS: This study used a multimodal data collection approach to assess the first five years of California's parity implementation (from 2000 to 2005). Telephone interviews were conducted with 68 state-level stakeholders, and in-person interviews were conducted with 77 community-based stakeholders. Six focus groups included 52 providers, and six included 32 consumers. A semistructured interview protocol was used. Interview notes and transcripts were coded to facilitate analysis. RESULTS: Health plans eliminated differential benefit limits and cost-sharing requirements for certain mental disorders to comply with the law, and they used managed care to control costs. In response to concerns about access to and quality of care, the state expanded oversight of health plans, issuing access-to-care regulations and conducting focused studies. California's parity law applied to a limited list of psychiatric diagnoses. Health plan executives said they spent considerable resources clarifying which diagnoses were covered at parity levels and concluded that the limited diagnosis list was unnecessary with managed care. Providers indicated that the diagnosis list had unintended consequences, including incentives to assign a more severe diagnosis that would be covered at parity levels, rather than a less severe diagnosis that would not be covered at such levels. The lack of consumer knowledge about parity was widely acknowledged, and consumers in the focus groups requested additional information about parity. CONCLUSIONS: Experiences in California suggest that implementation of the 2008 federal parity law should include monitoring health plan performance related to access and quality, in addition to monitoring coverage and costs; examining the breadth of diagnoses covered by health plans; and mounting a campaign to educate consumers about their insurance benefits.
