Comparative Study
Surgical trends in the treatment of diseases of the lumbar spine in Utah's Medicare population, 1984 to 1990.
Chronic low back pain is a major source of disability in this country. The rate of surgical treatment for back disorders varies between small geographic areas in the northeastern United States. A statewide database was utilized to determine rate of surgery for mechanical low back problems in Utah's Medicare population from 1984 to 1990. ⋯ There was no significant correlation between the number of surgeons performing back surgery and the rate of surgery. The variation and increase in back surgery rates in Utah's Medicare population are likely related to changes in the use of surgery for treatment of spinal stenosis and not to an increase in the number of back surgeons. Further investigation is needed to understand better the reasons for the observed increase in back surgery rates.

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.
