Background

Rib fractures are common in trauma patients and are associated with significant morbidity and mortality. Adequate analgesia is essential to avoid the complications associated with rib fractures. Opioids are frequently used for analgesia in these patients. This study compared the effect of a multimodal pain regimen (MMPR) on inpatient opioid use and outpatient opioid prescribing practices in adult trauma patients with rib fractures.

Study design

A pre-post cohort study of adult trauma patients with rib fractures was conducted at a Level I trauma center before (PRE) and after (POST) implementation of an MMPR. Patients on long-acting opioids before admission and those on continuous opioid infusions were excluded. Primary outcomes were oral opioid administration during the first 5 days of hospitalization and opioids prescribed at discharge. Opioid data were converted to morphine milligram equivalents (MMEs).

Results

Six hundred fifty-three patients met inclusion criteria (323 PRE, 330 POST). There was a significant reduction in the daily MME during the second through fifth days of hospitalization; and the average inpatient MME over the first five inpatient days (23 MME PRE vs. 17 MME POST, p = 0.0087). There was a significant reduction in the total outpatient MME prescribed upon discharge (322 MME PRE vs. 225 MME POST, p = 0.006).

Conclusion

The implementation of an MMPR in patients with rib fractures resulted in significant reduction in inpatient opioid consumption and was associated with a reduction in the quantity of opiates prescribed at discharge.
