Disparities in Antidiabetic Medication Discontinuation Between Non-Hispanic White and Black Beneficiaries in Medicare Across Diabetes Belt and Surrounding Area
A sampling strategy for longitudinal and cross-sectional analyses using a large national claims database
Importance: The United States (US) Medicare claims files are valuable sources of national healthcare utilization data with over 45 million beneficiaries each year. Due to their massive sizes and costs involved in obtaining the data, a method of randomly drawing a representative sample for retrospective cohort studies with multi-year follow-up is not well-documented. Objective: To present a method to construct longitudinal patient samples from Med…
Disparities in the Use of Diabetes Screening in Appalachia
PURPOSE: The Appalachian region presents disproportionately high rates of chronic disease compared to the rest of the United States. Early diagnosis of diabetes through screening is an important step in reducing diabetes complications. This study examines disparities in the use of diabetes screening in Appalachia. METHODS: We analyzed 2009 and 2010 Behavioral Risk Factor Surveillance System data for 96,111 adults aged ≥45 years from 11 Appalachia…
Accelerometer-Monitored Sedentary Behavior and Observed Physical Function Loss
Objectives. We examined whether objectively measured sedentary behavior is related to subsequent functional loss among community-dwelling adults with or at high risk for knee osteoarthritis. Methods. We analyzed longitudinal data (2008–2012) from 1659 Osteoarthritis Initiative participants aged 49 to 83 years in 4 cities. Baseline sedentary time was assessed by accelerometer monitoring. Functional loss (gait speed and chair stand testing) was reg…
Sedentary Behavior as a Risk Factor for Physical Frailty Independent of Moderate Activity
Objectives. This prospective longitudinal study investigated the association between baseline objectively measured sedentary time and 2-year onset of physical frailty. Methods. We studied 1333 Osteoarthritis Initiative participants 55 to 83 years of age who were at risk for physical frailty, as assessed via low gait speed ( Results. The incidence of physical frailty in this high-risk group was 20.7 per 1000 person-years. Greater baseline sedentar…
Individual, facility, and program factors affecting retention in a national weight management program
Greater attention to individualized consultation, accessibility to the program, and facility factors including staffing and physical activity resources may improve retention
Association Between Chronic Illness Complexity and Receipt of Evidence-based Depression Care
BACKGROUND: The rate of guideline concordance with antidepressant treatment for persons with depression is low. The problem may be even more pronounced for patients with depression and other multiple chronic conditions (MCC). OBJECTIVES: To study, for persons with new depressive episodes, the association between MCC and the likelihood of receiving guideline-concordant depression treatment. RESEARCH DESIGN: Retrospective cohort study using Veteran…
Effects of Welfare and Maternal Work on Recommended Preventive Care Utilization Among Low-Income Children
Objectives. We examined how maternal work and welfare receipt are associated with children receiving recommended pediatric preventive care services. Methods. We identified American Academy of Pediatrics–recommended preventive care visits from medical records of children in the 1999–2004 Illinois Families Study: Child Well-Being. We used Illinois administrative data to identify whether mothers received welfare or worked during the period the visit…
Predialysis Nephrology Care and Costs in Elderly Patients Initiating Dialysis
BACKGROUND: Access to nephrology care before initiation of chronic dialysis is associated with improved outcomes after initiation. Less is known about the effect of predialysis nephrology care on healthcare costs and utilization. METHODS: We conducted retrospective analyses of elderly patients who initiated dialysis between January 1, 2000 and December 31, 2001 and were eligible for services covered by the Department of Veterans Affairs. We used …
Age and Racial/Ethnic Disparities in Arthritis-Related Hip and Knee Surgeries
BACKGROUND: Nearly 18 million Americans experience limitations due to their arthritis. Documented disparities according to racial/ethnic groups in the use of surgical interventions such as knee and hip arthroplasty are largely based on data from Medicare beneficiaries age 65 or older. Whether there are disparities among younger adults has not been previously addressed. OBJECTIVE: This study assesses age-specific racial/ethnic differences in arthr…
Veterans’ Access to and Use of Medicare and Veterans Affairs Health Care
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 o…

Rates of lower-extremity amputation and arterial reconstruction in the United States, 1979 to 1996
OBJECTIVES: This report describes trends in the rates of lower-extremity amputation and revascularization procedures and vascular disease risk factors. METHODS: We analyzed trends in National Hospital Discharge Survey data for 1979 through 1996 and in National Health Interview Study data for 1983 through 1994. RESULTS: Despite a decline between 1983/84 and 1991/92, by 1995/96 the rate of major amputation had increased 10.6% since 1979/80. The ear…
