Hospital pharmacy-based service for patient-controlled analgesia.

A hospital pharmacy-based patient-controlled analgesia (PCA) service is described. The pharmacy department at a 255-bed community hospital instituted a comprehensive PCA service in 1985. Pharmacists were given thorough training in the clinical aspects of pain management and were taught how to use the PCA device; nurses also received instruction. An order for PCA is issued by a physician, who may then delegate decisions about medication choice, duration of therapy, and device settings to a clinical pharmacist. The pharmacist reviews the order and evaluates the patient's status. If PCA is appropriate, the pharmacist selects the analgesic agent and PCA device settings and prepares a pharmacy monitoring card. Orders for syringes are filled in the central pharmacy or by the decentralized pharmacist. Each order is entered into the i.v. drug profile and the i.v. drug computer file, and a narcotics control card is completed. The nurse programs the device, instructs the patient, and records the patient's level of pain control on a PCA-monitoring record. The pharmacist observes patients daily and records observations and changes on the pharmacy monitoring card. Use of the PCA service has grown from an average of 56 patient days per month in 1985 to 919 in 1989, and pharmacy department revenue has increased accordingly. A moderate increase in workload has been absorbed without the need for an increase in staff. Surveys show broad acceptance of the service by physicians, nurses, and patients. A hospital pharmacy-based PCA service offered patients better control of pain, allowed pharmacists to demonstrate competence in non-distributive functions, increased the visibility of the pharmacy department, and was a source of revenue.
