The diffusion of health care fraud
Many studies have examined the diffusion of health care innovation but less is known about the diffusion of health care fraud. In this paper, we consider the diffusion of potentially fraudulent Medicare home health care billing in the United States during 2002-16, with a focus on the 21 hospital referral regions (HRRs) covered by local Department of Justice (DOJ) anti-fraud "strike force" offices. We hypothesize that patient-sharing across home h…
Costing Medical Care
This paper describes how the PORTS are using data from the Medicare administrative records systems to study the medical care costs of specific conditions. The general strengths and weaknesses of the Medicare databases for studying cost related issues are discussed, and the relevant data elements are examined in detail. Changes in the nature of the data collected over time are noted. Information is provided on how the PORTS are using these data to…
Using Medicare Claims for Outcomes Research
Medicare claims databases have several advantages for use in constructing episodes of care for outcomes research. They are population-based, relatively inexpensive to obtain, include large numbers of cases, and can be used for long-term follow-up. However, the sheer size of these claims databases, along with their primarily administrative (as opposed to clinical) nature, requires that researchers take special care in using them. The 10 PORTs usin…
Studying Outcomes and Hospital Utilization in the Elderly
That veterans aged 65 years and older are eligible to receive care either in the Veteran Affairs (VA) health care system or in the private sector under Medicare confounds the analysis of veterans' health services utilization and outcomes in two ways. First, changes in eligibility or financial barriers to access with regard to either system influence veterans' decisions about where to seek needed care. Second, analyses of VA care for elderly veter…
Overcoming potential pitfalls in the use of Medicare data for epidemiologic research
We used Medicare data bases and US Census data to address two questions critical to the use of Medicare files for epidemiologic research. First, we examined the degree to which the population enrolled in the Medicare program is similar to the elderly resident population of the United States, as estimated by the US Census. We found small differences in the total population estimates but substantial differences by age and race. Second, we found tha…
Risk of carotid endarterectomy in the elderly
We used the Medicare claims files to describe operative mortality for 2,089 New England residents over the age of 65 who underwent carotid endarterectomy in 1984 and 1985. For patients ages 65 to 69, the risk of death within 30 days of surgery was 1.1 percent, (95% confidence interval = 0.5, 2.1), for those ages 70 to 74, 2.8 percent (1.7, 4.4), for those ages 75 to 79, 3.2 percent (1.8, 5.2), and for those over age 80, 4.7 percent (2.3, 8.5). Ne…
