- Throughout the 1980s, the number of laboratory tests performed in the United States grew at an annual rate of over 10%, and laboratory costs accounted for approximately 10% of overall health care expenditures.
Recently, the influence of capitation, emphasis on cost-effectiveness, and changing roles among specialists and primary care physicians have begun to affect the growth of laboratory testing.
We examined the impact of managed care on the economics of the clinical chemistry laboratory at Vanderbilt University Medical Center, Nashville, Tenn, to define the relative position of the clinical laboratory in the managed care environment of an academic medical center.
- The following data were prospectively collected between fiscal years 1984/1985 and 1995/1996 : number of inpatients and outpatients, average length of stay, number of laboratory tests, total laboratory revenue, direct costs (consisting of salary and consumable costs), and number of full-time-equivalent (FTE) personnel.
Using these data, we derived the following parameters : revenue and direct cost per patient, and revenue and productivity per FTE.
- Between 1984/1985 and 1995/1996 the number of inpatients and outpatients increased 33% and 155%, respectively.
Laboratory utilization, expressed as tests per patient, increased from 17 to 22 for inpatients between 1984/1985 and 1991/1992, and then sharply declined to 14. (...)
