Effect of a Multimodal Analgesic Protocol on Short-Term and Long-Term Opioid Use After Orthopaedic Trauma.

OBJECTIVE

To determine whether the use of a multimodal analgesic protocol reduced short-term and long-term opioid use in patients hospitalized after orthopaedic trauma.

DESIGN

Retrospective pre-post intervention study.

SETTING

Regional, academic, Level 1 trauma center in Central Kentucky.

PATIENTS/

PARTICIPANTS

Patients were hospitalized after orthopaedic injury before (n = 393) and after (n = 378) the implementation of a multimodal analgesic protocol.

INTERVENTION: The intervention involved a multimodal analgesic protocol consisting of acetaminophen, ibuprofen/ketorolac, gabapentinoids, skeletal muscle relaxants, and standardized doses of opioids plus standardized pain management education before hospital discharge.

MAIN OUTCOME MEASUREMENTS: End points included discharge opioid prescription, days' supply and daily morphine milligram equivalent (MME), and long-term opioid use after hospitalization. Opioid use in the 90 days before and after hospitalization was assessed using state prescription drug monitoring program data.

RESULTS

Discharge opioid prescription rates were similar in the intervention and control cohorts [79.9% vs. 78.4%, odds ratio (OR) 1.30 (0.83-2.03), P = 0.256]. Patients in the intervention cohort received a shorter days' supply [5.7 ± 4.1 days vs. 8.1 ± 6.2 days, rate ratio 0.70 (0.65-0.76), P < 0.001] and lower average daily MME [34.8 ± 24.9 MME vs. 51.5 ± 44.0 MME, rate ratio 0.68 (0.62-0.75), P < 0.001]. The incidence of long-term opioid use was also significantly lower in the intervention cohort [7.7% vs. 12.0%, OR 0.53 (0.28-0.98), P = 0.044].

CONCLUSIONS

Implementation of a multimodal analgesic protocol was associated with reductions in both short-term and long-term opioid use, including long-term opioid therapy, after orthopaedic trauma.
