This article examines the impact of greater management involvement by the medical director on efficiency of bed allocation in the intensive care unit (ICU) or critical care unit. Managerial involvement is modeled using a principal components approach in terms of perceived supervision, conflict resolution regarding bed allocation at critical times, extent of control over treatment, and employment status. ⋯ It was found that greater involvement by medical directors in the day-to-day management of the ICU significantly reduces the average occupancy rate in ICUs and also the probability of patients misallocated to the ICU, suggesting superior resource allocation in ICUs as a result. These results also suggest that the managerial impact of the medical director is greater in ICUs in high-occupancy hospitals.

Many studies have identified physicians' recommendation as the single most important predictor of mammography use. Health services utilization is a complex phenomenon, and the contribution of the different dimensions of health services utilization on mammography use is underresearched. This study examines the specific contribution of health services utilization variables in a multivariate model of the recency of mammography use for women aged 50 to 59 years. ⋯ Multivariate predictors of the recency of mammography are: having an education higher than high school, working outside home, not living in a remote area, suffering from benign breast disease, and not perceiving one's own health as good. The volume of general and gynecologic medical care is associated with the recency of mammography in independent logistic models that include women's predisposing, enabling, and need factors. This study shows that even in a universal third-party payer health care system, physicians are missing opportunities to promote breast cancer screening.

Randomized Controlled Trial Clinical Trial
Medicare reimbursement for preventive care. Changes in performance of services, quality of life, and health care costs.
A randomized, controlled trial was conducted to assess the effects of a financial and office systems intervention to increase preventive care in physicians' offices for patients aged 65 years or older. A total of 1,914 patients from 10 primary-care medical practices in central North Carolina were randomized within practices to an intervention and a usual-care control group. The intervention consisted of full Medicare reimbursement to physicians for preventive care and health promotion packages (thus making these services free for patients), regular prompting of physicians to routinely schedule preventive care visits, a new office system in which nurses carried out many preventive procedures, and a form for charting preventive care. ⋯ Relative to the $294 per patient 3-year cost to Medicare for waivered services, the intervention was reimbursed-cost neutral or slightly cost reducing ($190 over 3 years) for Medicare. It is concluded that adding reimbursement for preventive services to Medicare--even with the office systems changes made in this study--will not by itself lead to effective implementation of preventive services in community medical practices. To enhance patient benefit from preventive services, greater attention needs to be focused on an organized approach to patient follow-up.

Cataract surgery is the most frequently performed surgical procedure on Medicare beneficiaries, with an annual cost to the Medicare program of more than $3.4 billion. In this study, the relationship between demographic, environmental, and provider-related factors, and the likelihood that cataract surgery will be performed on a Medicare beneficiary were assessed. The association between likelihood of cataract surgery and patient age, sex, race, income, and latitude of residence was examined, as was the association with the supply of ophthalmologists and optometrists in each region, and the allowed charge for cataract surgery and cost of practice in a region. ⋯ The person-based model additionally demonstrated that increased likelihood of undergoing cataract surgery was associated with increasing age from 65 to 94 years, white race, and living in a zip-code area with mean income greater than $15,000. Neither analysis detected a statistically significant association between the concentration of ophthalmologists per 1,000 Medicare beneficiaries and the regional rate of, or an individual's likelihood of, cataract surgery. Compared with the geographic variation in provision of other surgical procedures, the variation in cataract surgery across large geographic areas observed in this analysis was relatively low.(ABSTRACT TRUNCATED AT 400 WORDS)

Prospective payment has created incentives for hospitals to identify physicians who are responsible for high or excessive rates of resource use. However, at teaching hospitals it is unclear whether individual attending or resident physicians account for a substantial portion of the observed variations in hospital resource use. To explore this issue, case-mix adjusted hospital length of stay and ancillary resource use at a university teaching hospital for 7,667 consecutive discharges on general medicine wards and 7,566 discharges on medical subspecialty wards were evaluated. ⋯ Furthermore, labeling attending physicians as high or low hospital resource utilizers based on data from one month of attending duty (mean admissions = 33 +/- 7) would be scarcely better than randomly classifying them (kappas ranged from -0.05 for length of stay on subspecialty services to 0.18 for pharmacy use on general medicine services). In conclusion, in this university teaching hospital, attendings and residents account or a small, although statistically significant, amount of the variation in hospital resource use. It would be impractical for the hospital to reliably profile the resource use intensity of individual physicians.
