摘要:

This study evaluates the determinants of insurance coverage in the 18–24- year-old population using the National Medical Care Utilization and Expenditure Survey. Three specific issues are addressed: 1) the characteristics of the insured versus uninsured, 2) the reason given by the uninsured for not having coverage, and 3) the role of employment status and other variables in determining insurance status. An important consideration is whether age or usual activity is more important in its effect on insurance status. The results show that employment is the strongest predictor of insurance status in all age and usual activity subgroups. Generally, permanent/full-time workers are most likely to be insured. An exception to this trend is found for those attending school who are also permanent/part-time workers. These individuals are more likely to be insured than permanent full-time workers who are in school. Furthermore, young adults with lower incomes, less education, rural residence, not married, hispanic ethnicity, and Western geography are the least likely to be insured. The findings of this analysis can be used by policymakers to identify the mechanisms that can best enhance insurance coverage among young adults.

摘要:

A computer model has been developed to determine cost-effectiveness of screening and treatment for diabetic retinopathy from a societal viewpoint. This model was used to evaluate biannual and annual screening programs using ophthalmoscopy, fundus photography with a “nonmydriatic camera,” and photography with a “mydriatic camera.” Computations were performed for three subpopulations formed by patients with younger onset diabetes (age at diagnosis < 30 years) of 5 years or more duration, with older onset diabetes (age at diagnosis ≥ 30 years) who are taking insulin, and with older onset diabetes not taking insulin. Population characteristics are from a well-described southern Wisconsin population where data are available, but the computer model may be specialized to other populations. Generally costs of screening programs appear to be recovered by avoided costs of blindness in the population subgroups taking insulin; however, the cost of screening programs generally are not recovered by avoiding costs of blindness in the older onset population subgroup not taking insulin. It was estimated that supplying annual examination with mydriatic fundus photography as a screening program to a cohort of 1,000 diabetics from the younger onset population who have been diagnosed at least 5 years and who are currently not receiving care might save 319 sight years over the lifetime of the cohort. This program will save 62 sight years in an older onset cohort who are taking insulin, and 21 sight years in the older onset population not taking insulin (all benefits are presented as present values computed with an annual discount rate of 5%). Other programs achieve slightly lower savings in each subpopulation.

摘要:

The Continuous Medicare History Sample File (CMHSF) was used to derive an estimate of the lifetime direct medical expenses attributable to two chronic diseases, lung cancer and female breast cancer. These two cancers are the leading cancer causes of death in men and women in the United States. They inflict large costs on the population, both direct and indirect, but the costs have been difficult to measure. The primary obstacle to quantification is the intermittent and long-term nature of treatment for these diseases. A complete record of expenses cannot usually be obtained from one source, however, a review of all the national health surveys, as well as the Medicare statistical files identified the CMHSF, which is maintained by the Health Care Financing Administration in a format suitable for calculation of cumulative medical expenses. Some of the pertinent features of the CMHSF include the following: 1) it is a nationally representative sample of the Medicare population, 2) it is longitudinal covering an 8-year period from 1974 to 1981, 3) it captures the majority of medical expenses for each enrollee, and 4) it can be linked to other national data bases such as the National Death Index. Charges for three phases of cancer treatment were derived from the file: initial therapy, maintenance care, and terminal care. A method is described for computing the present value of lifetime treatment costs from the phase-specific charges. The lifetime cost of treating breast cancer in 1984 dollars is $36,926 and lung cancer is $12,510.

摘要:

The impact of a national education program based on the dissemination of written guidelines for the treatment of breast, colorectal, and ovarian cancer was investigated in Italy. Through a survey of 770 physicians exploring their knowledge and attitudes and a review of medical records of 1,483 patients assessing current clinical practice, this study examined whether 1) the guidelines reached the target population of physicians, 2) they were effective in shaping doctors' opinions, and 3) care patterns conformed with the guidelines. Overall, the net effect of the intervention appeared to be limited in terms of actual diffusion, attributable influence, and impact. As for diffusion, only 60%, 47%, and 44% of doctors were aware of breast, colorectal, and ovarian cancer guidelines, respectively. Although doctors who were aware of the guidelines had more appropriate opinions than those who were not, overall agreement with recommendations was often unsatisfactory. With reference to guidelines recommendations, quality of care was far from optimal, especially in relation to diagnosis and staging. Marked variations in compliance with recommendations emerged with values ranging from 37% to 89%, from 48% to 82%, and from 10% to 97% for breast, colorectal, and ovarian cancer, respectively, and this held true even in hospitals where the larger awareness of the guidelines might have been expected to result in better quality care. It was concluded that any thorough assessment of the impact of educational interventions should include a careful analysis of the strategy and process of dissemination. The availability of clinically relevant messages must also be realistically considered before deciding whether the “guidelines approach” is the strategy most likely to succeed.

摘要:

This study examined the impact of Philadelphia's mandatory Medicaid case management program (HealthPASS) on adequacy of prenatal care and birth outcomes among enrollees. A sample of 217 deliveries for HealthPASS patients at the Hospital of the University of Pennsylvania (HUP) during 1988 was compared with a matched sample of 1988 deliveries at HUP for whom the payor was Pennsylvania's traditional fee-for-service Medicaid program. Inpatient charts for all 434 subjects were abstracted for information on sociodemographic characteristics, substance use during pregnancy (cigarettes, alcohol, and drugs), course and extent of prenatal care, and birth outcomes including birth weight, gestational age, and mortality. No significant differences were detected between the HealthPASS and Medicaid groups, suggesting that the mandatory managed care program neither improved nor impeded access to needed services. These results were not surprising in view of the fact that HealthPASS actually did little to change provider or patient behavior with respect to obstetrical care. Both the HealthPASS and Medicaid groups experienced low rates of adequate prenatal care (39%) and high rates of low birth weight (20%). Also disturbing was the finding that at least 46% of women smoked during pregnancy, at least 20% drank alcohol, and at least 17% used cocaine. These findings support the need for continued efforts to improve both access to, and content of, prenatal care for the urban poor.

摘要:

This article examines the quality of acute episodic care for five diagnostic categories amenable to one-visit diagnosis and treatment at the nation's largest chain of investor-owned ambulatory care centers. A total of 803 medical records were audited for five common conditions and measured against specific protocols. In four of the five diagnostic categories studied—pharyngitis, otitis media, vaginitis, and use of tetanus immunization—42–97% of patients received care that met or exceeded the standards set by a panel of practicing academic physicians. In follow-up of an incidental high blood pressure reading, however, study physicians met the standard only 24% of the time. Some overprescribing and overtreatment with immunizations were detected. As far as comparison is possible to other studies, results suggest that care in this setting falls within the range of experience that has been reported for other types of practices. In spite of direct economic incentives to increase volume, little evidence was found of overuse of ancillary tests or unnecessary scheduling of repeat visits.
