Distribution of behavioral science faculty in United States medical schools: 1968-1969 and 1978-1979.

The Association of American Medical Colleges' faculty profiles were analyzed for 117 U.S. medical schools for the years 1968/1969 and 1978/1979. The growth of behavioral science faculty more than matched that of all medical school faculty (i.e. 78 vs 65%) in full-time tenure-track positions over this 10-year period. Most behavioral science medical school faculty are psychologists. Although still small in numbers, faculty from other disciplines such as anthropology and sociology have gained increasing acceptance, and these 117 medical schools now employ at least 20 full-time economists and 13 who have earned degrees in political science. The growth of behavioral science faculty has been primarily in clinical departments, and those who are associated with independent departments of behavioral science remained virtually static (87 vs 88) over this 10 year period.

Radiographic contrast improvement by means of slit radiography.

It is generally believed that properly constructed high ratio grids are very efficient in removing radiographic scatter. The authors show that grids inherently transmit substantial amounts of contrast-degrading scatter and suggest a better method of eliminating it. A system of moving paired slits produces radiographic images with higher contrast than do grids at the same tube voltage. The diagnostic implications are discussed.

Cost analysis of the Novacor Left Ventricular Assist System as an outpatient bridge to heart transplantation.

Three patients were bridged to heart transplantation with the wearable Novacor Left Ventricular Assist System (Baxter Healthcare Corp., Oakland, CA) (LVAS). Two have been transplanted and discharged. The third patient remains at home. Hospitalization costs, which include the unit room charge, admission profile to the unit, and daily supply charge, were determined for all patients and compared. The patients were transferred from the surgical intensive care unit to a telemetry unit once they were hemodynamically stable. The projected hospitalization costs, if the patients had remained in the hospital, were calculated to determine probable savings for the third party payer. The average period from admission to placement of the Novacor LVAS was 15 days (range, 7-21 days). The average hospitalization cost from admission to time of Novacor left ventricular assist device implant was $2,240/day, and the average hospitalization cost after implant to discharge was $1,570/day. Hospitalization cost savings were $2,632 for the first patient, $5,922 for the second patient, and $132,124 for the third patient, who has not been transplanted. Although the number of patients is small, the daily hospitalization cost was higher before the Novacor LVAS was implanted. This is related to the severity of the disease and the length of stay in a surgical intensive care unit. There also is a significant cost savings for the third party payer, especially if the patient has to wait a significant amount of time before heart transplantation. These are important considerations in this time of managed care.
