An ecological study of the effectiveness of mammography in reducing breast cancer mortality
OBJECTIVES: The purpose of this study was to determine the relation of screening mammography to breast cancer incidence and case fatality. METHODS: In a sample of White female Medicare beneficiaries hospitalized in 1990-1991, age-adjusted breast cancer incidence and 2-year case fatality rates were estimated and compared with the frequency of mammographic screening from a population-based survey. RESULTS: The average rates for incidence, case fata…
Atrial fibrillation as a risk factor for stroke
OBJECTIVES: This study examined the relationship between atrial fibrillation and (1) stroke and (2) all-cause mortality. METHODS: All eligible Medicare patients older than 65 years of age hospitalized in 1985 were followed up for 4 years. Kaplan-Meier and Cox proportional hazards models were used for assessment of risk of stroke and mortality. RESULTS: A total of 4,282,607 eligible Medicare patients were hospitalized in 1985. The mean age was 76.…
Surgery for colorectal cancer
This study examined surgery for colorectal cancer among Medicare beneficiaries 65 years of age or older with an initial diagnosis in 1987 (n = 81 579). Black patients were less likely than White to undergo surgical resection (68% vs 78%), even after age, comorbidity, and location and extent of tumor were controlled for. Among those who underwent resection, Black patients were more likely to die (a 2-year mortality rate of 40.0% vs 33.5% in White …
Lumbar spine surgery and mortality among Medicare beneficiaries, 1986
OBJECTIVES. The purpose of this study was to compare lumbar spine surgical procedures by age, gender, and number of comorbidities with respect to mortality in patients 65 years of age and older in the United States. METHODS. A 100% sample of the 1986 Medicare inpatient Health Care Financing Administration claims files databases involving lumbar spine surgical procedures was analyzed. RESULTS. Lumbar spine surgery in 34,418 patients (median age = …
