Academic Detailing of Meperidine at a Teaching Hospital

Abstract

Meperidine (Demerol) is an opiate analgesic that is not considered first-line therapy for most pain management indications because of concerns about its safety and efficacy. Inpatient data from a 417-bed community teaching hospital revealed high use of meperidine in oral, IM, and IV forms. A multifaceted academic detailing approach was employed to change prescribing behavior and decrease meperidine use. This approach included conducting two concurrent Medication Use Evaluations; Grand Rounds presentations for pharmacy staff, nurses, and medical residents; solicitation of opinion leaders; pocket and table-top cards; newsletter articles; and provision of pharmaceutical care. Comparing the number of meperidine doses dispensed per adjusted patient day before and after the intervention, use was reduced by 0.0966 doses per patient (P < 0.05: 95% CI, 0.0955 to 0.0977). The number of patients receiving meperidine was reduced by 2.43% (P < 0.05: 95% CI, 1.97 to 2.88). This translates into a relative reduction of 29.5% in patients receiving meperidine and a relative reduction of 31% in meperidine doses dispensed per patient after academic detailing initiatives vs before. Eighty-five percent of standard orders were changed to improve therapy; these changes included converting meperidine to morphine or hydromorphone, decreasing cumulative acetaminophen daily dosages, using controlled-release and immediate-release opioids for pain management when oral therapy was tolerated, and combining modalities with different mechanisms of action for synergy and to decrease potential adverse effects from larger dosages of single entities. Academic detailing of meperidine resulted in short-term changes in prescribing patterns and decreased meperidine use at this institution. Long-term implications for pain management have not yet been assessed.
