Concentration of Physician Services Across Insurers and Effects on Quality: Early Evidence From Medicare Advantage
BACKGROUND: A growing proportion of Medicare beneficiaries is covered by private insurers through Medicare Advantage, yet little is known about how these plans are structured in terms of relationships with physicians and implications for quality of care. OBJECTIVE: The objective of this study was to assess whether greater physician concentration of services across insurers was associated with higher quality in Medicare Advantage (MA), overall and…
Exploring the Relationship Between Inpatient Facility and Physician Services
OBJECTIVES: Medicare hospitalizations involve both facility and physician services. Although several studies analyze hospital-level variations in Medicare inpatient facility and inpatient physician services per admission, few studies directly explore the relationship between these services. Theoretically, inpatient facility and physician services may be complements or substitutes. That is, an increase in facility services may lead to an increase …
The Impact of Practicing in Multiple Hospitals on Physician Profiles
Although physicians are all too familiar with the psychologic impact of having multiple responsibilities, the associated impact on practice styles has not been examined systematically. To provide some data on the effects of "work dispersion," we examined the hypothesis that the inpatient resource use of physicians would rise with the number of hospitals in which they work. Data for 1991 from Medicare's National Claims History File were used to pr…

State Border Crossing for Medicare Hospital Admissions
The purpose of this analysis was to determine the extent of state border crossing by Medicare beneficiaries to obtain inpatient hospital care. Estimating state border crossing for inpatient admissions is important for both policy and research reasons. From a policy perspective, Congress has mandated that the Secretary of Health and Human Services explore the establishment of Volume Performance Standards (VPS) at the subnational level. The state h…
Contractual Arrangements Between HMOs and Primary Care Physicians: Three-Tiered HMOs and Risk Pools
Concern about certain contractual arrangements between health maintenance organizations (HMOs) and primary care physicians has led policymakers to consider curbing these arrangements; one law has already been passed. However, these arrangements are complex and their impact is neither obvious nor well understood. This article first presents a conceptual approach to understanding the relationship between HMOs and primary care physicians and discuss…
Physician Charges in the Hospital: Exploring Episodes of Care for Controlling Volume Growth
Medicare physician payments are growing rapidly. At least 40% of the annual growth is due to volume increases. Reforms passed in 1989 include volume performance standards that attempt to control volume by linking future physician fee increases to volume growth. There is concern that defining the entire nation as the risk pool will result in an unworkable volume performance standard. One way to improve incentives is to create a separate volume per…
The Impact of Administratively Necessary Days on Hospital Costs
When patients remain in the hospital because no room can be found for them in nursing homes, the additional days are called administratively necessary. This study examines the impact of administratively necessary days on hospital operating costs. With the hospital as the unit of analysis, cost is regressed on hospital characteristics. While administratively necessary days are not measured directly, independent variables include determinants of ad…
HMO Enrollment and Medicaid: Survival Analysis with a Weibull Function
This paper analyzes the length of enrollment in Health Maintenance Organizations (HMOs) by performing secondary data analysis. It estimates a Weibull survival function using only simple regression. For middle-class enrollees in one HMO, the hazard rate (the disenrollment rate for the remaining members of a cohort) falls sharply with the length of enrollment. For medicaid beneficiaries allowed to remain in the fee-for-service sector, the hazard ra…
Regression Toward the Mean in Medical Care Costs: Implications for Biased Selection in Health Maintenance Organizations
As more Americans choose among insurance plans, the possibility of biased selection increases in importance. Although regression toward the mean is recognized as a common problem in evaluating social programs, it has generally been ignored in studies of biased selection. Suppose that people are included in a group simply because they had expenditures in one year $100 below the mean; that is, health status or other risk factors are not part of the…

Campaign Contributions and Legislative Voting: Milk Money and Dairy Price Supports
M W fANY MEMBERS of the press and the public apparently believe that interest groups buy influence by contributing to political campaigns. This belief has been cited as reason for Congress either publicly to finance congressional campaigns or to place a limit on the amount of monies that a candidate may receive from political action committees. In spite of this public discussion, few scholars have investigated systematically whether campaign cont…
