National survey of hospital-based pharmacokinetic services

The status of pharmacokinetic services in the nation's hospitals was studied. A questionnaire was mailed in February 1995 to all 252 respondents to ASHP's 1994 national survey of hospital-based pharmaceutical services who indicated the provision of pharmacokinetic services in their institution. Ninety-eight completed questionnaires were returned (40.2% response rate). The pharmacokinetic services provided required an average of 19.1 person-hours per week, tended to be provided by staff pharmacists, were managed by the pharmacy department, tended to be most focused on aminoglycosides and vancomycin, required an average of 60 notes in patient charts per month, and relied on both computers and calculators for deriving values. There was little contact with patients during the consultation process. Drug concentration measurements tended to be scheduled by service providers, but confidence in the accuracy of the timing of dose administration and blood sampling was limited. Respondents believed that the services tended to be supported by other hospital personnel and that they were successful. There was very little expectation that the workload for providing pharmacokinetic services would increase in the near future. A national survey of hospital-based pharmacokinetic services showed that it took 19 hours per week on average to provide the services, that the focus was on aminoglycosides and vancomycin, and that the services were perceived to be supported by other departments.
