OBJECTIVE We report the results of a population based analysis of all health services used and charges incurred over a one-year period among a community based cohort of persons with a diagnosis of arthritis [including both osteoarthritis (OA) and rheumatoid arthritis (RA)] compared to a similar cohort of individuals from the same community who have never(More)
OBJECTIVE The authors sought to determine acute ambulatory- and hospital-billed charges for the Olmsted County, Minnesota Multiple Sclerosis (MS) Disability Prevalence Cohort and compare them to those incurred by the general population. METHODS Billed charges for 155 people with clinically definite or laboratory-supported MS were compared with those of(More)
OBJECTIVE To determine the cost-utility of low-dose misoprostol prophylaxis in rheumatoid arthritis (RA) patients treated with nonsteroidal antiinflammatory drugs (NSAIDs). METHODS Prospectively collected, population-based data on 57 RA patients' preferences (obtained using the category scaling and time trade-off techniques), charge data from a(More)
To address the paucity of patient-level data regarding the effectiveness of Medicare's prospective payment system (PPS), we conducted a population-based study of inpatient hospitalizations among individually identified elderly residents of Olmsted County, Minnesota, 1970-1987. A 4.3% increase in total days of care/1000 population from 2,652/1,000 in 1970 to(More)

Employers have instituted various cost-containment measures based in part on reports of wide variations in rates of utilization and the assumption that unnecessary or inappropriate utilization of medical(More)
OBJECTIVE Compared to rheumatoid arthritis (RA), osteoarthritis (OA) is considered much more benign and much less costly. We sought to describe the economic effects of RA and OA, in terms of the indirect and nonmedical expenditures, compared to nonarthritic controls. METHODS Using our unique population based data resources, we developed a model for(More)

MATERIAL AND METHODS In this Mayo Clinic Institutional Review Board-approved study, we obtained a stratified random sample of patients(More)
Some investigators have suggested that information on quality of care in intensive-care units (ICUs) may be inferred from mortality rates. Specifically, the ratio of actual to predicted hospital mortality (A/P) has been proposed as a valid measure for comparing ICU outcomes when predicted mortality has been derived from data collected during the first 24(More)
To elicit the opinions of practicing internists who had graduated from a single internal medicine residency program about the adequacy of their training and its relevance to their medical practice, we mailed a survey to 1,342 physicians who had spent at least 1 year in the Mayo internal medicine residency training program. Of this group, 703 alumni (52%)(More)
We conducted a pilot study examining the relative preferences for various nonsteroidal antiinflammatory drug associated adverse gastrointestinal events and misoprostol prophylaxis for these events. Thirty patients with rheumatoid arthritis volunteered to participate. A trained nurse interviewer administered the structured pretested interview. Respondents(More)
