SUBJECTS: Three hundred and eighty nine thousand and two hundred and thirty-six patients diagnosed with cancer betw…
Race and sex differences in long-term survival rates for elderly patients with pulmonary embolism
OBJECTIVES: The goal of this study was to provide estimates of race- and sex-specific survival rates over a 10-year period for a cohort of 49,752 Medicare patients admitted to the hospital in 1984 with a diagnosis of pulmonary embolism. METHODS: Data were derived from Medicare Provider Analysis and Review Record inpatient claims files and the National Death Index file. RESULTS: For a primary diagnosis of pulmonary embolism, median survival times …
Trends in pulmonary embolism mortality in the US elderly population
OBJECTIVES: This study determined race-, age- and sex-specific trends in 30-day pulmonary embolism mortality rates. METHODS: Medicare beneficiaries with a primary or secondary discharge diagnosis of pulmonary embolism from 1984 to 1991 (n = 391,991) were examined. RESULTS: For a primary diagnosis of pulmonary embolism, mortality rates declined by 15.2% and 16.0%, respectively, for White male patients 65 to 74 years old and 75 years or older. Ther…
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 …
The Relationship of Hospital Ownership and Teaching Status to 30- and 180-Day Adjusted Mortality Rates
Hospital characteristics have been shown previously to be associated with variations in the probability of death within 30 days of admission. In the current study, the authors extend the examination of the relationship between hospital type to both short-term and long-term adjusted mortality. Observed and predicted 1988 hospital mortality rates were obtained from the Health Care Financing Administration (HCFA). A total of 3,782 acute care hospita…
Assessing providers of coronary revascularization
OBJECTIVES. Current methods to evaluate quality of care are usually limited to reviews of individual cases or comparisons of hospital mortality rates. We present an alternative method that compares complication rates adjusted for patient characteristics. METHODS. Detailed clinical data that were specifically designed for quality comparisons of providers of revascularization procedures were abstracted from the medical records of 1998 Medicare pati…
Race and sex differences in mortality following fracture of the hip
This paper describes the all-cause mortality experience, following a fracture of the hip, of 712,027 persons covered by the Medicare program from 1984 through 1987. White women experienced the lowest mortality rate (17.2 per 1000 person-months), followed by Black women (22.9 per 1000 person-months), Black men (33.5 per 1000 person-months), and White men (33.7 per 1000 person-months). The observed race-sex differences in survival were found at all…
The Relationship of Hospital Characteristics and the Results of Peer Review in Six Large States
To determine which characteristics of hospitals may be related to a higher quality of care, the association of hospital characteristics with the outcomes of medical record review by state Peer Review Organizations (PROs) was studied. The two data sources were: 1) the AHA 1986 Annual Survey of Hospitals and 2) reviews completed between July 1987 through June 1988 from six large PROs. For each hospital the percentage of cases that failed physician …
Association of waist to hip ratio and family history with the prevalence of NIDDM among 25,272 adult, white females
The independent association of waist to hip ratio (WHR), relative weight, and family history with the prevalence of non-insulin dependent diabetes mellitus (NIDDM) was investigated in a population of 25,254 White females in the United States and Canada. A multivariate logistic analysis yielded standardized odds ratios of 1.47, 1.46, 1.54, and 1.14 for family history index, WHR, relative weight, and age, respectively
Hip fracture incidence among the old and very old
Data were obtained from the Health Care Financing Administration and the Department of Veterans Affairs (formerly called Veterans Administration) on all hospital discharges among the elderly population from 1984 through 1987 and combined with census estimates to calculate incidence rates of hip fracture for the elderly population of the United States. Rates for White women were the highest, reaching 35.4 per 1,000 per year among 95 year-olds. Com…
Hospital Characteristics and Mortality Rates
The Health Care Financing Administration (HCFA) publishes hospital mortality rates each year. We undertook a study to identify characteristics of hospitals associated with variations in these rates. To do so, we obtained data on 3100 hospitals from the 1986 HCFA mortality study and the American Hospital Association's 1986 annual survey of hospitals. The mortality rates were adjusted for each hospital's case mix and other characteristics of its pa…
Natural history of obesity in 6,946 women between 50 and 59 years of age
A health survey of 6946 50-to-59 year-old women of TOPS, an organization for weight reduction, was used to study the natural history of obesity. Weight history was compared for four groups of women divided on the basis of their per cent above ideal body weight (IBW) in their 50s (less than 20%, 20-49%, 50-99% and 100+%). In each of the four groups, the majority of women were not obese by age 20. Sixteen per cent of the women who were 100+% overwe…
Evaluation of a New Strategy for Continued Stay Review in Hospitals
A classification of in-patients by "reason for admission" (RFA) is described and compared with the classification by diagnosis. The RFA classification assigns length of stay on the basis of twenty-five reasons for admission for adult medical-surgical cases. Length of stay norms for the RFA method were developed and compared to diagnosis specific norms (dx norms). A group of 500 charts was subjected to simulated continued stay review using both RF…
Association between juvenile onset obesity and severe adult obesity in 73, 532 women
The association between juvenile obesity and severe adult obesity was examined using a questionnaire completed by 73,532 weight conscious women. Relative obesity as an adult was determined by the ratio Weight/Height. The question, "Were you considered a fat child?" determined childhood weight status. Analysis of the data revealed that severely obese women (regardless of age) were 2.4 times more likely than normal weight women to have been fat chi…
