Abstract:
Morphine is a preferred narcotic since meperidine forms toxic metabolites. Determinants of meperidine use have been poorly described. The objective of this study is to explore factors associated with the ordering of meperidine versus morphine. Retrospective chart review of adult patients, randomly selected based on orders for morphine or meperidine. 1552 orders were written for 670 patients. Of these, 36% were for meperidine. In multivariable analysis, the ordering of meperidine was associated with the following variables in decreasing order of importance: physician specialty, total doses received, hospital location, patient race, age and insurance, and physician gender. More orders for meperidine were written for those receiving fewer doses. Though meperidine has little role in the routine management of hospital pain, we found it continues to be used frequently. Importantly, meperidine is ordered more frequently for patients who receive shorter courses of narcotics. Our study suggests that interventions targeted at more appropriate use of meperidine rather than complete elimination might be more acceptable to physicians while minimizing the risk of toxicity.
Insights
Meperidine is frequently used for shorter pain management courses, despite risks. Interventions promoting appropriate use, not elimination, may reduce toxicity and improve physician acceptance.
Area of Science:
- Pharmacology
- Clinical Medicine
- Health Services Research
Background:
- Morphine is often preferred over meperidine due to the latter's toxic metabolite formation.
- Factors influencing meperidine prescribing patterns remain poorly understood.
Purpose of the Study:
- To investigate the determinants associated with prescribing meperidine versus morphine.
- To identify patient and physician factors linked to meperidine utilization.
Main Methods:
- Retrospective chart review of adult patients with orders for morphine or meperidine.
- Analysis of 1552 orders from 670 patients to determine prescribing patterns.
Main Results:
- Meperidine accounted for 36% of all narcotic orders reviewed.
- Physician specialty, total doses, hospital location, patient race, age, insurance, and physician gender were significantly associated with meperidine ordering.
- Meperidine was more frequently ordered for patients receiving fewer doses or shorter courses of narcotics.
Conclusions:
- Meperidine continues to be frequently prescribed, particularly for patients with shorter treatment durations.
- Targeted interventions for appropriate meperidine use, rather than complete discontinuation, could mitigate toxicity risks and gain physician acceptance.
