Anabolic Steroid and Stimulant Use in North American Sport between 1850 and 1980
The use of drugs to enhance performance has been a feature of athletic competition since ancient times. This review discusses the use of anabolic steroids and stimulants by athletes to improve performance during the later half of the nineteenth century and during most of the twentieth century. Included are discussions of the development and medical background of testosterone and anabolic steroids, how the use of steroids progressed from medical u…
Comparison of two methodologies to measure agricultural occupational fatalities
Agricultural occupational fatalities in Pennsylvania for the years 1985-87 were followed up. Supplemental data concerning the occupation of the deceased and circumstances of the fatal accident were obtained from a family member. The number of fatalities designated as agriculturally and occupationally related by the National Traumatic Occupational Fatality (NTOF) system was compared with the number of fatalities identified by using alternative cri…
The Hidden Future Supply of Foreign Medical Graduates
The number of foreign medical graduates (FMGs) as reported by the American Medical Association (AMA) has registered increases in recent years far exceeding the Department of Health and Human Services' (DHHS) published forecasts. The DHHS projections of new entrants have been derived from the number of postgraduate year-one positions filled by FMGs. Apparently, the FMG supply is augmented by physicians who enter by other paths. By using AMA data, …
Seroprevalence of HIV antibody among individuals entering the Iowa Prison System
From January 1 to April 30, 1986, all individuals entering the Iowa prison system were tested for antibody to the human immunodeficiency virus (HIV). Sera were collected on 363 newly incarcerated inmates, 389 inmates returning to prison, and 107 forensic psychiatric patients. Three of the 859 serum samples (0.3 per cent) tested during this study were reactive by ELISA (enzyme-linked immunosorbent assay) testing, but none reactive by the Western b…

Capitation Payment for Pharmacy Services
Four areas of cost were analyzed in the expanded capitation drug program: total program costs; drug costs, escrow account distribution, and administrative costs. Total program costs were, on average, 9% higher under capitation. Drug costs, however, were 3% lower than under fee-for-service (FFS) reimbursement. This discrepancy is probably because pharmacists were not at financial risk under the program, the capitation rates were higher than intend…
Capitation Payment for Pharmacy Services
Results of a two-county pilot study in Iowa revealed that capitation may have significant advantages over fee-for-service (FFS) reimbursement in the Medicaid drug program. Consequently, the capitation program was expanded to 32 counties on April 1, 1981 and continued through December 31, 1981. Another 32 counties were used as part of a before:after/experimental:control design. Pharmacists were paid 80% of projected drug expenditures in advance ba…
Capitation Payment for Medicaid Pharmacy Services
Although pharmacy organizations have been instrumental in the movement to repeal antisubstitution laws, there is evidence that under the current fee-for-service system pharmacists have not exercised their newly obtained prerogatives freely. A previous study has demonstrated that paying pharmacists on a capitation basis for their Medicaid patients effects a highly significant increase in the rate of generic substitution. The present study was cond…
Does chiropractic utilization substitute for less available medical services
In Muscatine, Iowa, a medically underserved rural area, a cohort study of health care utilization was made before and after a significant increase in medical manpower. There was a slight increase, rather than a decrease, in the use of chiropractic services associated with the growth in the physician manpower pool. The level of access to physician services was not a significant predictor of chiropractice utilization
The Effect of a Group Practice on Rural Health Attitudes and Behavior
The opportunity to join a group practice has been identified as a successful inducement for physicians to locate in rural areas. Less is known of the effects of group practice on the health attitudes, behavior and status of the rural communities in which they are established. A random survey of households was conducted in 1972 in a rural Midwestern area, prior to the establishment of a community-sponsored multispecialty primary care group practic…
Capitation Payment for Pharmacy Services
This article evaluates changes in the rate of generic substitution as well as the appropriateness of such changes in dispensing behavior when the conventional fee-for-service system for reimbursement of pharmacists is replaced by a capitation system. The fee-for-service system under Medicaid usually covers ingredient costs plus a fixed professional dispensing fee. The capitation system provides a cash payment per Medicaid eligible at the first of…
Does Duration of Membership in a Prepaid Group Health Plan Affect Utilization
Real-time spectroscopic ellipsometry has been applied in situ in an Ar+ Xe F2 beam-etching experiment to study the roughening of Si(100) etched by Xe F2 at room temperature. The role of initial surface conditions has been examined. For the etching of hydrogen-terminated (H:)Si(100), the roughness evolution as a function of Xe F2 dose can be characterized by an initially fast roughening phase followed by a slower, final roughening phase. Similar b…
Selection of Regression Models for Health Care Data
We discuss several linear and nonlinear regression models and their appropriateness in modeling a set of data from a cohort study of the use of medical services in a prepaid medical plan. Although computational considerations once forced researchers to use linear models almost exclusively, modern computer hardware and efficient algorithms have made it possible to use nonlinear models almost as easily as linear ones. Thus, in choosing a regression…
The Effect of Duration of Membership in a Prepaid Group Health Plan on the Utilization of Services
This study concerns the changes in the use of medical care services as the duration of membership in a prepaid group plan increases. For each of ten cohorts of members of the prepaid group practice in Columbia, Maryland, the use of provider visits (for both "well" care and "problem-oriented" care), of inpatient hospital services, and of prescribed drugs were determined, and time trends for each type of service were developed. The rate of total pr…
