A decade of experience with a clinical pharmacokinetics service.
The development, operation, and functions of the pharmacokinetics service at Memorial Medical Center of Long Beach (MMCLB) are described, and the data used to determine the quality and cost-effectiveness of the service are presented. Current functions of the pharmacokinetics service at MMCLB include making brief written comments about the interpretations of serum drug concentrations (SDCs) and oral recommendations to physicians on dosage adjustment; provision of written consultations with dosage recommendations; provision of drug information, education, and research; and development of drug dosing guidelines for the pharmacy and medical staff. During the 10-year existence of this service, costs have been justified on the basis of not only revenue generated by the service (in the form of "drug concentration scheduling" and "drug concentration evaluation" fees charged to patients) but also by cost savings resulting from the prevention of inappropriate, misleading, and potentially dangerous SDCs. An audit conducted in 1986 showed that the policy of having pharmacists schedule the sampling times for SDCs saves about $500,000 annually. Quality assurance has been documented by auditing compliance with and therapeutic effectiveness of dosing guidelines and by working with laboratory personnel to identify and prevent spurious SDC results and assay errors. The methods used by the pharmacokinetics service at MMCLB to document the benefits of the service have been vital in proving both its cost-effectiveness and its positive effect on patient care.
