Health Expenditure Concentration and Characteristics of High-Cost Enrollees in CHIP
Devising effective cost-containment strategies in public insurance programs requires understanding the distribution of health care spending and characteristics of high-cost enrollees. The aim was to characterize high-cost enrollees in a state's public insurance program and determine whether expenditure inequality changes over time, or with changes in cost-sharing policies or program eligibility. We use 1999-2011 claims and enrollment data from th…
Adverse Selection in the Children’s Health Insurance Program
This study investigates whether new enrollees in the Alabama Children's Health Insurance Program have different claims experience from renewing enrollees who do not have a lapse in coverage and from continuing enrollees. The analysis compared health services utilization in the first month of enrollment for new enrollees (who had not been in the program for at least 12 months) with utilization among continuing enrollees. A second analysis compared…
The Impact of Texting Bans on Motor Vehicle Crash–Related Hospitalizations
We used a panel design and the Nationwide Inpatient Sample from 19 states between 2003 and 2010 to examine the impact of texting bans on crash-related hospitalizations. We conducted conditional negative binomial regressions with state, year, and month fixed effects to examine changes in crash-related hospitalizations in states after the enactment of a texting ban relative to those in states without such bans. Results indicate that texting bans we…
Trends in the Utilization and Outcomes of Medicare Patients Hospitalized for Hip Fracture, 2000-2008
Hip fractures remain highly debilitating events and pose significant challenges for the financing of public health insurance programs
Impact of Texting Laws on Motor Vehicular Fatalities in the United States
Using a panel study design, we examined the effects of different types of texting bans on motor vehicular fatalities. We used the Fatality Analysis Reporting System and a difference-in-differences approach to examine the incidence of fatal crashes in 2000 through 2010 in 48 US states with and without texting bans. Age cohorts were constructed to examine the impact of these bans on age-specific traffic fatalities. Primarily enforced laws banning a…

The Effects of the Balanced Budget Act of 1997 on Home Health and Hospice in Older Adult Cancer Patients
BACKGROUND: Home health and hospice services can constitute important elements in the continuum of care for older adults diagnosed with cancer. The Balanced Budget Act (BBA) of 1997 included provisions affecting those services. OBJECTIVES: The first objective of this study is to assess the effect of the BBA of 1997 on home health and hospice service utilization in older cancer patients. The second objective is to estimate the effect of the BBA of…
Effects of Specialty Hospitals on the Financial Performance of General Hospitals, 1997–2004
Hospital specialization has become a controversial topic, culminating in a moratorium issued in 2003 by Congress directing the Centers for Medicare and Medicaid Services to cease payments to new physician-owned specialty hospitals for those Medicare and Medicaid patients referred by physicians with a financial interest in the facility. This paper focuses on one important economic question: does the presence of specialty hospitals in a market affe…
Free-Standing Ambulatory Surgery Centers and Hospital Surgery Volume
This paper examines the association of free-standing ambulatory surgery centers (ASCs) with hospital surgery volume, using data from the 2002 Medicare Online Survey Certification and Reporting System and the American Hospital Association Annual Surveys of Hospitals. From 1993 to 2001, the number of ASCs per 100,000 population in metropolitan statistical areas (MSAs) increased by 150%. During the same period, hospital outpatient surgeries increase…
Graduated Drivers License Programs and Rural Teenage Motor Vehicle Fatalities
Context: Graduated drivers license (GDL) programs have been shown to reduce motor vehicle fatalities among 15‐ to 17‐year‐olds. However, the 20 most rural states have been the least likely to enact more stringent GDL policies. Purpose: Estimate the relationship of GDL programs and the number of traffic fatalities among 15‐ to 17‐year‐olds on rural interstate and noninterstate roadways. Methods: Analysis of 1992‐2002 Fatality Analysis Reporting Sy…
Tort Law and Medical Malpractice Insurance Premiums
This paper estimated the effects of tort law and insurer investment returns on physician malpractice insurance premiums. Data were collected on tort law from 1991 through 2004, and multivariate regression models, including fixed effects for state and year, were used to estimate the effect of changes in tort law on medical malpractice premiums. The premium consequences of national policy changes were simulated. The analysis found that the introduc…
Gasoline prices and motor vehicle fatalities
Fatal motor vehicle crashes per capita remained relatively stable over the 1990s, in spite of new traffic safety laws and vehicle innovations. One explanation for this stability is that the price of gasoline declined, which resulted in more vehicle miles traveled and potentially more fatalities. By using 1983–2000 monthly gasoline price and fatality panel data and fixed effects specifications, this study exploits within‐state variation over time …
The Effects of CON Repeal on Medicaid Nursing Home and Long-Term Care Expenditures
Certificate-of-need (CON) and construction moratorium laws are used widely by states as a potential mechanism for constraining Medicaid nursing home expenditures. However, there is only limited empirical work examining whether these policies are effective at lowering Medicaid spending. Using aggregate state-level data from 1981 through 1998, this study found that states that repealed their CON and moratorium laws had no significant growth in eith…
Do “Any Willing Provider” and “Freedom of Choice” Laws Affect HMO Market Share
This study examines the effects of “any willing provider” (AWP) and “freedom of choice” (FOC) laws on the market share of health maintenance organizations (HMOs) in metropolitan statistical areas over the period 1989–95. We use pooled cross-section time-series regression techniques with year and state fixed effects. HMO market share is hypothesized to be a function of state laws, market characteristics, and state preference for managed care regul…
The Effects of Managed Care on Physician and Clinical Integration in Hospitals
OBJECTIVE: To empirically estimate the effects that managed care has had on physician and clinical integration in urban hospitals. DATA SOURCES: The 1993 Hospital-Physician Relationship Survey conducted for the Prospective Payment Assessment Commission, augmented with data from a variety of secondary sources. The entire 1,495 responding hospitals were used to construct measures of integration; 591 responding hospitals in urban areas were used for…
Physician and Clinical Integration Among Rural Hospitals
The pressures for closer alignment between physicians and hospitals in both rural and urban areas are increasing. This study empirically specifies independent dimensions of physician and clinical integration and compares the extent to which such activities are practiced between rural and urban hospitals and among rural hospitals in different organizational and market contexts. Results suggest that both rural and urban hospitals practice physician…
Beer Taxes, Workers' Compensation, and Industrial Injury
The apparent effects of beer taxes, workers' compensation rules, and other factors on reported rates of lost work-days due to injury are estimated. The data used are for injury rates for two-digit SIC industries at the state-level pooled over 1975–85. The results indicate that higher beer tax rates are associated with lower rates of injury lost work-days. More generous workers' compensation payments generally are associated with higher reported i…
Simplifying the Assessment of Rural Emergency Medical Services Trauma Transport
OBJECTIVES The authors determine whether assessments of effects of rural emergency medical service (EMS) system characteristics on trauma outcomes (using patient-level data) are significantly biased if the Injury Severity Score (ISS) is not available. METHODS The data are from ambulance trip reports merged with the trauma registry data for the Georgia EMS region VI trauma center hospital, located in Augusta. All 294 trauma patients for the rural …

Rural Emergency Medical Services
This study sought to describe the volume of use, mix of patients, origin and destination of runs, times and distances to care, and the volume of clinical services provided in a rural emergency medical services region. This study summarizes all 6,080 rural emergency ambulance trip reports filed from April through September 1991 from the 12 rural counties surrounding Augusta, GA. Rural ambulances are regularly used and are used extensively by elder…
On Defining Small Areas
This study explores the relationship between small area and economic approaches to defining hospital markets. Both approaches attempt to link populations receiving care with providers who deliver it. The approaches differ fundamentally, however, in their view of the role of alternative sources of inpatient services. The small area approach attempts to minimize the number of hospitals in a market. Economic approaches attempt to include substitute …
Group Health Insurance
The authors examine the premium consequences of alternative health insurance provisions by estimating pricing regressions for group insurance with data on 9, 019 fee-for-service plans offered by larger firms in the private sector. They find that cost-sharing at the point of purchase, especially for hospital care, significantly lowers fee-for-service premiums. However, some aspects of plan design that are often touted as cost-reducing, such as sel…
Determinants of Rural Travel Distance for Obstetrics Care
This study examines the distances traveled for inpatient obstetrics care by women residing in rural Alabama in 1983 and 1988. During that time 23 rural hospitals in the state stopped providing obstetrics services and mean travel distances increased by 6.8 miles. However, in 1988 50% of rural pregnant women bypassed the nearest rural hospital still providing obstetrics services. Multivariate techniques are used to examine the effects of distance a…
Physician Integration Strategies and Hospital Output
Physician integration strategies are attempts to bring physicians into hospital administration by giving them a role on the hospital board, employing them in administrative or clinical capacities, or expanding the administration issues dealt with by medical staff committees. This study used a production function model to examine whether such strategies affect hospital output, measured as case mix-adjusted discharges. The article hypothesizes that…
Case shifting and the Medicare Prospective Payment System
We assessed impacts of the Medicare Prospective Payment System (PPS) during its first two years of operation (1984-85) on 467 hospitals using data from the Commission on Professional and Hospital Activities and from the American Hospital Association. Medicare discharges as a per cent of total discharges remained constant between 1983 and 1985, but the per cent of uninsured patients increased, especially at large public hospitals. The number of Me…

The Role of Physicians in Hospital Production
We use a translog production function approach to examine the effects of medical staff physicians on hospital production, and how their effects differ in teaching and nonteaching hospitals. In teaching hospitals, we also focus on the special role of medical residents. We find that physicians have a strong positive influence on the productivity of other inputs, and that they are substitutes for other resources. Controlling for patient casemix caus…

Hospital Selection Into Multihospital Systems
The growing literature on multihospital systems (MHS) has concentrated on assessing system performance without a concurrent examination of the assumptions related to the conditions under which hospitals and systems affiliate with each other. Using a net present-value framework the current study develops and tests a model that explains the entry patterns of hospitals into multihospital systems. Specifically, we assess the role of the hospital's ma…
Medicare Prospective Payment and Posthospital Transfers to Subacute Care
This study analyzed the early effects of the Medicare Prospective Payment System (PPS) on the likelihood of hospital's discharging Medicare beneficiaries to skilled nursing facilities (SNFs), intermediate care facilities (ICFs), and home health agencies. It also examined length of stay before transfer. Discharge abstract data on patients in five DRG groups were studied. Data were obtained from 501 hospitals for the third quarters of 1980, 1983, 1…
Medicare Prospective Payment and the Use of Medical Technologies in Hospitals
Medicare's Prospective Payment System (PPS) created incentives to reduce the application of technology to hospitalized Medicare beneficiaries. Using data from 501 hospitals from 1980 and 1983-85, this study assesses changes in use of intensive care units and use of nonsurgical procedures before versus after implementation of PPS. The percent of hospitalized patients, both Medicare and non-Medicare, admitted to intensive care units increased post-…
