Objective: To estimate the effect of Medicare's prospective payment system for inpatient rehabilitation facilities on discharge functional status, community discharge, and length of stay., Design: Secondary analysis using data drawn from the American Medical Rehabilitation Providers Association subscription database. Eligible patients were Medicare and non-Medicare stroke patients discharged from inpatient rehabilitation facilities from 1998 through the first two quarters of 2006. Random effects panel data models were used to estimate the impact of prospective payment on motor and cognitive discharge function, the probability of discharge to the community and inpatient length of stay, controlling for patient, and facility characteristics., Results: The introduction of prospective payment was associated with small, statistically significant reductions in Functional Independence Measure discharge motor (-1.10) and cognitive (-0.15) scores and in the probability of discharge to the community (adjusted odds ratio: 0.87) for Medicare fee-for-service patients. Length of stay was substantially lower for both Medicare (-1.86 days) and (-2.16) non-Medicare fee-for-service patients., Conclusions: Further research is needed to determine whether the small reductions in patient function are persistent over time. This short-term evaluation of prospective payment system suggests minimal negative impact on stroke patient function at discharge because of the change in Medicare reimbursement but a decrease in likelihood of discharge to the community.

Objectives: We examined the impact of access to care characteristics on health care use patterns among those veterans dually eligible for Medicare and Veterans Affairs (VA) services., Methods: We used a retrospective, cross-sectional design to identify veterans who were eligible to use VA and Medicare health care in calendar year 1999. We analyzed national VA utilization and Medicare claims data. We used descriptive and multivariable generalized ordered logit analyses to examine how patient, geographic, and environmental factors affect the percent reliance on VA and Medicare inpatient and outpatient services., Results: Of the 1.47 million veterans in our study population with outpatient use, 18% were VA-only users, 36% were Medicare-only users, and 46% were both VA and Medicare users. Among veterans with inpatient use, 24% were VA only, 69% were Medicare only, and 6% were both VA and Medicare users. Multivariable analysis revealed that veterans who were black or had a higher VA priority were most likely to rely on the VA. Patient with higher risk scores were most likely to rely on a combination of VA and Medicare health care. Patients who lived farther from VA hospitals were less likely to rely on VA health care, particularly for inpatient care. Patients living in urban areas with more health care resources were less likely to rely on VA health care., Conclusions: VA health care provides an important safety net for vulnerable populations. Targeted approaches that carefully consider the simultaneous impacts of VA and Medicare policy changes on minority and high-risk populations are essential to ensure veterans have access to needed health care.

Context: Increasing prevalence of overweight/obesity and rapid aging of the US population have raised concerns of increasing health care costs, with important implications for Medicare. However, little is known about the impact of body mass index (BMI) earlier in life on Medicare expenditures (cardiovascular disease [CVD]-related, diabetes-related, and total) in older age., Objective: To examine relationships of BMI in young adulthood and middle age to subsequent health care expenditures at ages 65 years and older., Design, Setting, and Participants: Medicare data (1984-2002) were linked with baseline data from the Chicago Heart Association Detection Project in Industry (CHA) (1967-1973) for 9978 men (mean age, 46.0 years) and 7623 women (mean age, 48.4 years) (baseline overall age range, 33 to 64 years) who were free of coronary heart disease, diabetes, and major electrocardiographic abnormalities, were not underweight (BMI <18.5), and were Medicare-eligible (> or =65 years) for at least 2 years during 1984-2002. Participants were classified by their baseline BMI as nonoverweight (BMI, 18.5-24.9), overweight (25.0-29.9), obese (30.0-34.9), and severely obese (> or =35.0)., Main Outcome Measures: Cardiovascular disease-related, diabetes-related, and total average annual Medicare charges, and cumulative Medicare charges from age 65 years to death or to age 83 years., Results: In multivariate analyses, average annual and cumulative Medicare charges (CVD-related, diabetes-related, and total) were significantly higher by higher baseline BMI for both men and women. Thus, with adjustment for baseline age, race, education, and smoking, total average annual charges for nonoverweight, overweight, obese, and severely obese women were, respectively, 6224 dollars, 7653 dollars, 9612 dollars, and 12,342 dollars (P<.001 for trend); corresponding total cumulative charges were 76, 866 dollars, 100,959 dollars, 125,470 dollars, and 174,752 dollars (P<.001 for trend). For nonoverweight, overweight, obese, and severely obese men, total average annual charges were, respectively, 7205 dollars, 8390 dollars, 10,128 dollars, and 13,674 dollars (P<.001 for trend). Corresponding total cumulative charges were 100,431 dollars, 109,098 dollars, 119,318 dollars, and 176,947 dollars (P<.001 for trend)., Conclusion: Overweight/obesity in young adulthood and middle age has long-term adverse consequences for health care costs in older age.

Background: People without major risk factors for cardiovascular disease in middle age live longer than those with unfavorable risk-factor profiles. It is not known whether such low-risk status also results in lower expenditures for medical care at older ages. We used data from the Chicago Heart Association Detection Project in Industry to assess the relation of a low risk of cardiovascular disease in middle age to Medicare expenditures later in life., Methods: We studied 7039 men and 6757 women who were 40 to 64 years of age when surveyed between 1967 and 1973 and who survived to have at least two years of Medicare coverage in 1984 through 1994. Men and women classified as being at low risk for cardiovascular disease were those who had the following characteristics at the time they were initially surveyed: serum cholesterol level, <200 mg per deciliter (5.2 mmol per liter); blood pressure, < or =120/80 mm Hg; no current smoking; an absence of electrocardiographic abnormalities; no history of diabetes; and no history of myocardial infarction. We compared Medicare costs for the 279 men (4.0 percent) and 298 women (4.4 percent) who had this low-risk profile with those for the rest of the study group, who were not at low risk. Health Care Financing Administration charges for services to Medicare beneficiaries were used to estimate average annual health care costs (total costs, those for cardiovascular diseases, and those for cancer)., Results: Average annual health care charges were much lower for persons at low risk - the total charges for the men at low risk were less than two thirds of the charges for the men not at low risk ($1,615 less); for the women at low risk, the charges were less than one half of those for the women not at low risk ($1,885 less). Charges related to cardiovascular disease were lower for the low-risk groups of men and women than for those not at low risk (by $979 and $556, respectively), and charges related to cancer were also lower (by $134 and $189)., Conclusions: People with favorable cardiovascular risk profiles in middle age had lower average annual Medicare charges in older age. Having optimal status with respect to major cardiovascular risk factors may result not only in greater longevity but also in lower health care costs.

1987 Medicare hospital mortality statistics for 255 New York hospitals (including 57 hospitals in New York City) were compared with 4,617 hospitals located in other states. An analysis of covariance examined how overall Medicare hospital mortality rates differed across states; these rates were adjusted for expected mortality, hospital bed size, and major teaching status. This study tested for the hypothesis that New York State had an average 30-day post-admission Medicare mortality rate significantly different from the mean hospital mortality rate for all states. The results indicated that New York State was -0.43 percentage points below the average risk-adjusted mortality rate of the other states (p < 0.0001). Although it remains speculative to what extent differences in adjusted Medicare hospital mortality are a function of quality of care, these results indicate that New York's historically high level of hospital regulation has not resulted in inferior patient outcomes.

This study examines variation in severity-adjusted Medicare hospital mortality rates across nine U.S. census regions. The extent to which regional variation is reduced by controlling for differences in hospital resources and structure, county-level population characteristics, and the level of federal SuperPRO-identified hospital quality problems is estimated. Hospital resources, population characteristics, and SuperPro process quality scores are significant predictors of hospital mortality rates, but they do not explain the important, highly significant regional differences observed after controlling for hospital case-mix severity.
