ABSTRACT
OBJECTIVES: Following earlier research which showed that certain types of physicians are more likely to be sued for malpractice, this study explored (1). whether graduates of certain medical schools have consistently higher rates of lawsuits against them, (2). if the rates of lawsuits against physicians are associated with their school of graduation, and (3). whether the characteristics of the medical school explain any differences found. DESIGN: Retrospective analysis of malpractice claims data from three states merged with physician data from the AMA Masterfile (n=30288). STUDY SUBJECTS: All US medical schools with at least 5% of graduates practising in three study states (n=89). MAIN OUTCOME MEASURES: Proportion of graduates from a medical school for a particular decade sued for medical malpractice between 1990 and 1997 and odds ratio for lawsuits against physicians from high and low outlier schools; correlations between the lawsuit rates of successive cohorts of graduates of specific medical schools. RESULTS: Medical schools that are outliers for malpractice lawsuits against their graduates in one decade are likely to retain their outlier status in the subsequent decade. In addition, outlier status of a physician's medical school in the decade before his or her graduation is predictive of that physician's malpractice claims experience (p<0.01). All correlations of cohorts were relatively high and all were statistically significant at p<0.001. Comparison of outlier and non-outlier schools showed that some differences exist in school ownership (p<0.05), years since established (p<0.05), and mean number of residents and fellows (p<0.01). CONCLUSIONS: Consistent differences in malpractice experience exist among medical schools. Further research exploring alternative explanations for these differences needs to be conducted.

OBJECTIVE: Despite increased recognition of the importance of development and growth of young children, formal developmental and behavioral screening often is not included in general pediatric practice. Barriers to the provision of developmental and behavioral screening are considerable; among them are the need for specialized training and uncertain reimbursement. This article develops a model for estimating the cost of providing pediatric developmental and behavioral screening that can be scaled to reflect a pediatric practice's patient population and choice of screening offered. METHODS: The framework for our scaleable cost model was drawn from work done in estimating the Resource-Based Relative Value Scale (RBRVS). RBRVS provides estimates of the work effort involved in the provision of health care services for individual Current Procedural Terminology codes. The American Academy of Pediatrics has assigned descriptions of pediatric services, including developmental and behavioral screening, to the Current Procedural Terminology codes originally created for adult health care services. The cost of conducting a screen was calculated as a function of the time and staff required and was loaded for practice costs using the RBRVS valuation. The cost of the follow-up consultation was calculated as a function of the time and staff required and the number of relative value units assigned in the RBRVS scale. RESULTS: The practice cost of providing developmental and behavioral screening is driven primarily by the time and staff required to conduct and evaluate the screens. Administration costs are lowest for parent-administered developmental screens ($0 if no assistance is required) and highest ($67) for lengthy, pediatric provider-administered screens, such as the Neonatal Behavioral Assessment Scale. The costs of 3 different groups of developmental and behavioral screening are estimated. The estimated per-member per-month cost per 0- to 3-year-old child ranges from $4 to >$7 in our 3 examples. CONCLUSIONS: Cost remains a significant barrier to greater provision of formal developmental and behavioral screening. Our scaleable cost model may be adjusted for a given practice to account for the overall level of developmental risk. The model also provides an estimate of the time and cost of providing new screening services. This model allows pediatric practices to select the mix of developmental screens most appropriate for their particular patient population at an acceptable cost.

The papers in this Special Supplement are based on research funded by the participating members of the joint Center for Health Management Research (CHMR) and Center for Organized Delivery Systems (CODS), and supported by the National Science Foundation under its Industry-University Cooperative Research Center Program. This 3-year research initiative from 1996 through 1999 involved 69 physician organizations (primarily organized medical groups as opposed to IPAs) associated with 14 organized delivery systems. The groups ranged in size from three to 958 with an average size of 76.4 and a median size of 25.0. Comparisons of the study groups with United States physician groups overall are shown in Table 1. The study groups are larger and more likely to be multispecialty than all groups in the United States. The organized delivery systems range in size from one hospital to 80 hospitals with an average of 21 hospitals per system and a median of 11 hospitals per system. They average 4.6 affiliated medical groups with a range from one to 23. The organized delivery systems range in total revenues in 1998 from $340 million to $6.2 billion with an average of $2.1 billion. All the study systems are not-for-profit. Most are located in single market areas, but several are located in multiple markets. For the most part, they represent some of the larger most experienced organized delivery systems in the country. Among the primary objectives of the study was to identify the factors most strongly associated with physician alignment with the health care system and the consequences for the implementation of evidence-based care management practices. The study was also designed to identify the barriers and facilitators to achieving such alignment and its consequences.

OBJECTIVES: To examine the association between the degree of alignment between physicians and health care systems, and interorganizational linkages between physician groups and health care systems. METHODS: The study used a cross sectional, comparative analysis using a sample of 1,279 physicians practicing in loosely affiliated arrangements and 1,781 physicians in 61 groups closely affiliated with 14 vertically integrated health systems. Measures of physician alignment were based on multiitem scales validated in previous studies and derived from surveys sent to individual physicians. Measures of interorganizational linkages were specified at the institutional, administrative, and technical core levels of the physician group and were developed from surveys sent to the administrator of each of the 61 physician groups in the sample. Two stage Heckman models with fixed effects adjustments in the second stage were used to correct for sample selection and clustering respectively. RESULTS: After accounting for sample selection, fixed effects, and group and individual controls, physicians in groups with more valued practice service linkages display consistently higher alignment with systems than physicians in groups that have fewer such linkages. Results also suggest that centralized administrative control lowers physician-system alignment for selected measures of alignment. Governance interlocks exhibited only weak associations with alignment. CONCLUSIONS: Our findings suggest that alignment generally follows resource exchanges that promote value-added contributions to physicians and physician groups while preserving control and authority within the group.

OBJECTIVES: To assess the extent to which market pressures, compensation incentives, and physician medical group culture are associated with the use of evidence-based medicine practices in physician organizations. METHODS: Cross-sectional exploratory study of 56 medical groups affiliated with 15 integrated health systems from across the United States, involving 1,797 physician respondents. Larger medical groups and multispecialty groups were overrepresented compared with the United States as a whole. Data are from two sources: (1) surveys of physicians assessing the culture of the medical groups in which they work, and (2) surveys of medical directors and other managerial key informants pertaining to care management practices, compensation methods, and the management and governance of the medical groups. Physician-level data were aggregated to the group level to attain measures of group culture and then merged with the data regarding care management, incentives, and management and governance. Stepwise multiple regression was used to examine the study hypotheses. RESULTS: As hypothesized, the number of different types of compensation incentives used (cost containment, productivity, quality) was positively associated with the comprehensiveness of care management practices. The degree of salary control (ie, market-based salary grades and ranges versus the use of bookings or fees and individual negotiation) was also positively associated with the deployment of care management practices. As hypothesized, market pressures in the form of percentages of health maintenance and preferred provider organization patients seen were generally positively associated with the use of care management practices. Organizational culture had no association except that a patient-centered culture in combination with a greater number of different types of compensation incentives used was positively associated with greater use of care management practices. CONCLUSIONS: Both compensation incentives and managed care market pressures were significantly associated with the use of evidence-based care management practices. The lack of association for culture may be due to the relatively amorphous nature of most physician organizations at this point.

BACKGROUND: Enthusiasm for the concept of care management (CM) has led to unprecedented growth in the number of guidelines and protocols, but provider organizations have struggled to enlist the active support and participation of physicians in CM activities. OBJECTIVES: To empirically examine the factors influencing physician participation in and attitudes toward CM activities. METHODS: Data on 1,514 physicians were used to predict physician attitudes toward CM and their perceptions of group CM behaviors. Dependent variables were modeled using two-stage Heckman selection bias models with fixed effects corrections. Independent predictors included physician- and group-level controls as well as six potential CM participation and attitude facilitators. RESULTS: Physician participation in the implementation phase of CM activities was positively related to participation and attitude. However, physician participation in the development phase may be negatively related to later participation in CM activities. Management involvement in development phase has mixed effects (positive or no effect), but their involvement in the implementation phase was somewhat negatively related to CM participation and attitude. Financial incentives for participation in CM activities and presence of a useful management information system also appeared to be positively related to attitude and participation. CONCLUSIONS: Appropriate physician and management involvement, as well as financial incentives and useful management information systems may facilitate physician participation in CM activities. Physician involvement in implementation of CM practices appears to be important, whereas their involvement in the development phase may be negatively related to later attitudes and participation. The findings call for a more in-depth understanding of the timing of physician input in CM activities.

BACKGROUND: Health care systems have developed many types of contracting vehicles with physicians. The immediate aim of these vehicles has been to foster physician commitment and alignment to the system. The ultimate aim of these vehicles has been to garner managed care contracts, reduce costs, and improve quality. To date, most of these vehicles have failed to improve physician commitment. This may be one reason why the ultimate outcomes have not been observed. Consequently, systems are experimenting with new methods to partner with physicians. One new method is to segment physicians into tightly linked and loosely linked strategic alliances and devote different levels of resources and attention to each. OBJECTIVES: This study evaluates whether the segmentation of physicians into tightly linked versus loosely linked strategic alliances improves the commitment of physicians to the system. The study then investigates which constituent elements of the tightly linked strategic alliances exhibit the greatest association with commitment. DESIGNS AND SUBJECTS: The study uses a cross-sectional design and survey data drawn from 1,965 physicians affiliated with 14 health care systems around the country. Tightly linked physicians typically practiced in hospital-sponsored group practices, whereas loosely linked physicians typically used the system's hospitals as their primary site of inpatient practice. MEASURES: Commitment is measured by seven different scales drawn from the literature on organizational commitment, loyalty, and identification. Some of the scales refer to physician attitudes, whereas others describe physician behaviors. The literature suggests that commitment is associated with both instrumental/utilitarian considerations (eg, older age, tenure with system, admissions to system, receipt of a stipend, etc.) as well as administrative involvement/participation considerations (eg, decision-making roles). A series of physician background and practice characteristics are used here to model these two types of factors. RESULTS: The study finds small but significant differences in commitment between physicians in tightly linked versus loosely linked alliances. Multivariate analyses suggest that instrumental/utilitarian factors (eg, age, receipt of stipend, percent of admissions to the system) may exhibit stronger associations with commitment than the physician's administrative involvement in the organization. CONCLUSIONS: To the degree that physician commitment is possible, systems should appeal to physicians' calculative motivations using extrinsic rewards rather than normative involvement in the organization.

OBJECTIVES: To examine the association between risk assumption by individual physicians and physician groups and the degree of alignment between physicians and health care systems. METHODS: A cross sectional comparative analysis using a sample of 1,279 physicians practicing in loosely affiliated arrangements and 1,781 physicians in 61 groups closely affiliated with 14 vertically integrated health systems. Measures of physician alignment were based on multiitem scales validated in previous studies and derived from surveys sent to individual physicians. Measures of risk assumption were developed from surveys sent to the administrator of each of the 61 physician groups in the sample and to physicians affiliated with these groups. Two stage Heckman models with fixed effects adjustments in the second stage were used to correct for sample selection and clustering respectively. RESULTS: After accounting for selection, fixed effects, and group and individual controls, physicians in groups with larger proportional revenue from managed care displayed greater normative commitment and system loyalty than physicians in groups with lower proportional managed care revenue. Individual-level managed care risk was also positively related to both normative commitment and group behavioral commitment to the system. Physicians in groups with larger physician equity positions expressed lower levels of normative commitment to the system. Physician productivity compensation was negatively related to all measures of alignment. Finally, group emphasis on individually-based incentives for staff physicians was negatively related to system identification. CONCLUSIONS: Our findings suggest that organizations must balance individually-based risk schemes with those that emphasize the performance of the group and the system to achieve long-term goals of loyalty, identification, and commitment to the system.

OBJECTIVES: To identify the barriers, facilitators, and potential better practices to achieving physician-system alignment. METHODS: Interviews using a semi-structured, open-ended protocol were conducted during a total of 18 site visits, each usually 2 days in length, covering multiple topics of physician group-system alignment. Interviews were conducted with members of the target physician group, key leaders of the health care system, and representatives of physicians not in the target group. The summary of the interviews for each of the site visits was analyzed to determine barriers, facilitators, and better practices for achieving more effective relationships between physician groups and health care systems. RESULTS: A number of barriers to more effective relationships between physician groups and health systems were identified. Barriers related to environment, culture, and information systems were most prevalent. Other major general areas of barriers encountered were physician leadership, group-system relationship, compensation and productivity, care management practices, group strategy, and accountability. Examples of practices that may help to resolve some of these issues were also identified. CONCLUSIONS: Physician-system relationships can and do cause problems for improving health care. The evidence from the conducted site visits suggests that specific strategies may help improve these relationships but more research is needed in order assess the actual impact of these strategies.

OBJECTIVE: To determine if an association exists between managed care penetration and perinatal deregionalization in Washington State. METHODS: The proportions of low birth weight (LBW) and very low birth weight (VLBW) deliveries were tabulated for each hospital in Washington State for the years 1989, 1993 and 1996. Level of perinatal care, degree of health maintenance organization (HMO) penetration, and maternal demographic characteristics including age, race, smoking, and Medicaid status were derived from state and national databases. Multiple linear regression analysis was performed for each hospital level to evaluate the association between change in proportion of LBW and VLBW deliveries and change in HMO penetration per hospital between each of the 3 years. RESULTS: From 1989 through 1993, the proportion of LBW deliveries significantly declined at level III hospitals and rose at level I and II hospitals. This trend reversed between 1993 and 1996. Very low birth weight deliveries demonstrated more limited and somewhat contrary results, significantly decreasing, then increasing in level I hospitals, and significantly increasing in level III hospitals from 1989 to 1993. After controlling for changes in maternal characteristics over time, changes in HMO penetration at the hospital level were not significantly associated with an increasing proportion of LBW or VLBW deliveries at nonlevel III hospitals. In some analyses, increasing HMO penetration actually was significantly associated with decreasing LBW and VLBW deliveries at nonlevel III hospitals. CONCLUSION: Despite continued growth in HMOs throughout the state, the trend toward deregionalization in Washington State noted in the early 1990s has not continued. At the hospital level, the increasing presence of HMOs is not significantly associated with perinatal deregionalization.

OBJECTIVE: We sought to understand why certain Medicaid managed care organizations (MMCOs) implemented child development services or programs and how they had done so. We also sought to identify barriers and facilitators to successful initiation and implementation of child development programs. METHODS: We conducted 9 key informant interviews and 4 site visits, and performed qualitative analyses to identify major themes across responses. RESULTS: We identified a small number of MMCOs with child development services. High-level support was crucial for program initiation; physician buy-in, staff support, and strong working relationships with outside health professionals or agencies were principal factors in successful program implementation. CONCLUSIONS: MMCOs that were committed to implementing child development services were successful in doing so, without external funding or regulatory mandate. The results provide valuable strategies for MMCOs interested in developing programs and for researchers and advocates interested in promoting child development services for low-income children.

OBJECTIVES: To assess the impact of total quality management (TQM) and organizational culture on a comprehensive set of endpoints of care for coronary artery bypass graft surgery (CABG) patients, including risk-adjusted adverse outcomes, clinical efficiency, patient satisfaction, functional health status, and cost of care. METHODS: Prospective cohort study of 3,045 eligible CABG patients from 16 hospitals using risk-adjusted clinical outcomes, functional health status, patient satisfaction, and cost measures. Implementation of TQM was measured by a previously validated instrument based on the Baldridge national quality award criteria. Organizational culture was measured by a previously validated 20-item instrument. Generalized estimating equations were used to control for potential selection bias, repeated measures, and intraclass correlation. RESULTS: A 2- to 4-fold difference in all major clinical CABG care endpoints was observed among the 16 hospitals, but little of this variation was associated with TQM or organizational culture. Patients receiving CABG from hospitals with high TQM scores were more satisfied with their nursing care (P = 0.005) but were more likely to have lengths of stay >10 days (P = 0.0003). A supportive group culture was associated with shorter postoperative intubation times (P = 0.01) but longer operating room times (P = 0.004). A supportive group culture was also associated with higher patient physical (P = 0.005) and mental (P = 0.01) functional health status scores 6 months after CABG. CONCLUSIONS: There was little effect of TQM and organizational culture on multiple endpoints of care for CABG patients. There is a need to examine further the relationships among individual professional skills and motivations, group and microsystem team processes, specifically tailored interventions, and organization-wide culture, decision support processes, and incentives. Assessing the impact of such multifaceted approaches is an important area for further research.

We explore the extent of "responsible purchasing" by employers--the degree to which employers collect and use nonfinancial information in selecting and managing employee health plans. Most firms believe that they have some responsibility for assessing the quality of the health plans they offer. Some pay attention to plan characteristics such as the ability to provide adequate access to providers and services and scores on enrollee satisfaction surveys. A more limited but still notable number of firms take specific actions based on responsible purchasing information. Because of countervailing pressures, however, it is not clear whether or not the firms most involved in responsible purchasing are signaling a developing trend.

OBJECTIVES: To assess the likelihood of health care legislation in the forthcoming 105th Congress in 5 areas: health care coverage, tax and Employee Retirement Income Security Act (ERISA) policy, Medicaid, Medicare, and managed care. DESIGN: Informal, semistructured conversations that took place in the months prior to the 1996 elections. POPULATION: Congressional health staff and administration officials. OUTCOME MEASURES: Unofficial, off-the-record personal opinions. RESULTS: Health care coverage initiatives to benefit children and unemployed persons are likely to be proposed, but have little chance of enactment; children are seen as well provided for under current Medicaid law, the strong economy and high employment levels lower concern for unemployed issues, and the effort required to pass the Kassebaum-Kennedy legislation needs time to settle. Tax proposals, such as medical savings accounts (MSAs), and ERISA amendments have no constituency; also, the MSA demonstration in Kassebaum-Kennedy will forestall further action. Medicaid is far less an issue than in the previous Congress, because spending has fallen unexpectedly, the bitter fight over block grants makes them unlikely to be revisited, and the administration is likely to enhance state flexibility through waivers. Medicare will be the subject of substantial action to defer impending insolvency temporarily, but there is virtually no chance that definitive long-term solutions will be enacted even though the underlying fiscal problems are thoroughly understood and recognized. Managed care will be the venue for numerous proposals designed to address specific consumer and quality issues. CONCLUSIONS: Four bitter years of fighting over health care issues has raised awareness of the problems, but has produced a political chemistry that is too rancorous to permit passage of significant legislation in the near future.

There have been recent increases in asthma prevalence, morbidity, and mortality in the United States. There is substantial evidence that problems in health care delivery may be contributing to these recent trends. Because of these recent changes, a reduction in asthma-related morbidity has been identified as a new national health objective for the year 2000. This article reviews some of the key aspects of patterns of asthma care in the United States, presents an overview of issues that may play a prominent role in the delivery of care, and provides an overview of the organization of the workshop.
