Prospective patient-controlled analgesia quality assurance: one year's experience.

The goal of this project was to develop a prospective patient-controlled analgesia (PCA) quality assurance (QA) program and evaluate its impact on patient care. Initial elements selected for inclusion into the QA were: patient satisfaction, pain relief, clarity of instructions, respiratory rate, and nausea and vomiting. Standards were initially set at 100% with the exception of nausea and vomiting, which was 90%. Preliminary evaluation in 26 patients indicated initial standards were unrealistically high. Standards were revised to 90% for all elements except respiratory rate, which was left at 100%. Nausea and vomiting were eliminated from the QA because it was difficult to establish a cause and effect relationship with narcotic. Data were collected through patient interviews and chart reviews on a bimonthly basis. Cumulative data on 297 patients revealed standards were met in all categories. Two systematic problems identified early in the QA were that there was no recording of respiratory rate and there was a high incidence of unclear instructions. As a result of pharmacist interventions, outcomes improved. Patient outcomes with PCA therapy can be improved using a prospective PCA QA program. Pharmacy Department's without resources for daily monitoring of PCA patients should consider implementing a prospective PCA QA program.
