摘要:

This paper reevaluates the recently reported excess mortality following transurethral resection of the prostate (TURP) for benign hypertrophy as compared with traditional open resection (OPEN). We studied survival through linkage of hospital discharge data with mortality data for the entire male population of Denmark (1977-85). For a maximum of 10.5 years 38,067 prostatectomy patients were followed. Adjusting for age and health status before surgery, TURP patients were subject to significantly higher levels of mortality than OPEN patients (RR = 1.19,95% confidence interval (1.15-1.24). The extent to which this difference is attributable to the surgical intervention itself remains an open question. The two groups of patients are quite different with regard to age and preoperative health status, and available data may not be sufficient to control such differences through statistical analysis. On the other hand, the difference in mortality persisted over calender time, even during periods when the pattern of utilization for the two procedures changed significantly (constant RR= 1.19, adjusting for age and comorbidity). The most important causes of death among Danish TURP patients differ from the causes suggested on the basis of previously reported Canadian data. The current evidence is thus ambiguous with regard to hypothetical biologic mechanismes behind the excess mortality over TURP patients. Further investigations are needed to evaluate the safety and effectiveness of prostate surgery.

摘要:

A two-group randomized experimental design was employed to assess the effects of monitoring and feedback on the compliance of 93 psychiatric outpatients treated with lithium. Compliance in both groups was measured using self-report, lithium level, appointment-keeping, and medication refill frequency. The experimental group was also monitored using a unique electronic device that records the time and day pills are removed. At the midpoint of the study, the experimental group received feedback about serum lithium levels and patterns of removing medications from the monitoring device while the control group received feedback about serum lithium levels only. The study demonstrated no sustained effect of the monitoring and feedback interventions on compliance.

摘要:

Physicians who participate in preferred provider organizations (PPOs) usually agree to various types of utilization review and sometimes discount their charges or agree to accept lower fees. This study was performed to determine whether they provided more or fewer services to their PPO patients than to their indemnity patients and whether the discounting resulted in lower expenditures for each episode of illness. In 1984, Metropolitan Life offered PPO coverage to Dade County (Florida) school board employees and dependents but only a standard indemnity plan to Dade County government employees and dependents. Episodes of care were examined for patients with chest pain, hypertension, joint pain, gastrointestinal or liver disorders, and lower back pain cared for by physicians who treated patients in both the PPO and indemnity employee groups. For PPO patients, charges per physician service were the same or lower, but total physician charges during an episode were higher. For services such as laboratory tests, diagnostic x-rays, and room and board, PPO and indemnity patients' charges were not significantly different.

摘要:

This study analyzed how the use and cost of pharmaceuticals varied by level of drug co-payment in a staff model health maintenance organization (HMO). An historical cohort design was used to study changes in drug utilization and drug costs in 19,982 continuously enrolled beneficiaries less than the age of 65. The beneficiaries initially had no drug co-payments, but experienced co-payment rates of $1.50, $3.00, and $3.00 plus other benefit changes during a threeyear period. A comparison cohort of 23,164 beneficiaries was selected from the same setting who were subject to no drug co-payment during the same time period. Data on the use and cost of medications were obtained from an automated data system. Adjusted analyses for each time period controlled for age, sex, years in the Group Health Cooperative (GHC), and prior year utilization (or cost). The initial $1.50 drug co-payment was associated with a drop of 10.7% in the number of prescriptions filled relative to change in the comparison cohort. The decrease was greatest for discretionary drugs at each level of copayment. The implementation of progressively greater levels of co-payments continued to have a significant effect on drug utilization since each co-payment level resulted in an additional reduction in drug utilization; 10.6% with the $3 co-payment and 12.0% when the $3 drug co-payment was combined with other cost-sharing provisions. Co-payments were associated with lower per capita drug costs and higher per prescription unit costs.

摘要:

This study examines the effect of ethnicity, race, and other socioeconomic and utilization variables on belonging to a fee-for-service or capitated plan by Medicare beneficiaries. Native-born beneficiaries cite health status, physical access to health care facilities, and income levels as affecting their choice. Immigrants, on the other hand, mention age, a lifestyle of living alone, and income as influencing their decision. Among foreign-born nationals, race appears to play an important role in choosing health care plans. A key factor affecting enrollment among immigrant populations appears to be the availability of ethnic sensitive providers of health care. While the elderly Hispanic immigrant population utilizes participating providers in prepaid plans catering to a Spanish-speaking population, the lack of similar facilities among predominantly black immigrant neighborhoods inhibits participation in HMOs by elderly immigrants from places such as Haiti and the Carribean Basin. Policy implications are discussed.

摘要:

Drug formularies are privotal tools for delineating and directing prescribing to the “drugs of choice.” Full realization of their potential has been hampered by insufficient comparative data on drug efficacy /safety and local resources for formulary development. However, misconceptions concerning fundamental formulary concepts pose an even more formidable obstacle. This article identifies statements illustrating formulary misconception a) made by physicians attending Pharmacy and Therapeutics Committee meetings during a threeyear period and b) appearing in published sources. The paper highlights basic objectives and operational requirements of an effective formulary, and contrasts this definition with 20 myths and misinformation culled from these two sources. Not only does such misinformation impair formulary development, many critics are so preoccupied with alleged shortcomings that progress in minimizing the real limitations of formularies has been impeded.

摘要:

The relative time cost unit (RTCU) is a proposed new system for valuing dental procedures that provides an alternative to traditional relative value units in fee-setting and reimbursement allowances. It incorporates personnel costs, task mixes, and task times into relative weights for dental procedures. The frequently performed procedure, “2-surface amalgam restoration,” is used to illustrate how the RTCU values are derived from hospital task analysis data. The RTCU, as a data-based construct, holds appeal for restructuring fee schedules and has been used for almost a decade by insurance companies to value dental services, construct fee schedules, and evaluate reimbursement to providers.

摘要:

Data from the 1982-1984 National Long-Term Care Survey were used in this paper to estimate the risk of nursing home use. The data revealed that 37% of a nationally representative sample of individuals dying between 1982 and 1984 used a nursing home sometime after turning 65. This proportion increased with longevity and was higher among females and whites and in the North Central and Western regions of the country. Because individuals now turning 65 have a longer life expectancy than the persons studied, they face an even higher remaining lifetime risk of nursing home use (43%). Assuming that past utilization patterns will continue, over half of the women and almost one-third of the men turning 65 in 1990 can be expected to use a nursing home sometime before they die.

摘要:

Effects on utilization and expenditures occurring concurrently with an expansion of coverage in the South Carolina Medicaid drug formulary were investigated. Data were collected for prescriptions, physician office visits, and outpatient and inpatient hospital visits. Data were evaluated for a cohort of 12,139 individuals who had at least one prescription claim and were continuously eligible for benefits during the two-year study. A repeated measures design was employed to control the differences between subjects. A multivariate analysis of variance was used to detect overall differences in utilization and expenditures. A priori comparisons of means were performed to detect changes in levels and rates of expenditures and utilization for each service. Increases were observed in the number of prescriptions, physician visits, and outpatient visits per person while the number of inpatient hospital admissions declined. Similarly, expenditures increased for all service areas except the inpatient hospital service. The proportion of variance explained by the formulary change was small in all service areas, but would be of practical significance because of the large number of Medicaid recipients affected. From a theoretical perspective, an association of a reduction in inpatient hospital use and expenditures following the elimination of drug formulary restrictions is particularly noteworthy. These findings support the thesis that medical care services should not be viewed in isolation but rather as a system of interrelated activities. Interventions in one portion of the system are mirrored by changes in utilization of other components. Frequently, private and public medical care programs are managed with organizationally distinct benefit budgets, which are controlled independently. In view of the results of this study, this organizational approach may lead to a suboptimal allocation of resources.
