Implementation of Multimodal Pain Protocol Associated With Opioid Use Reduction in Trauma Patients.

INTRODUCTION: Many trauma centers have adopted multimodal pain protocols (MMPPs) to provide safe and effective pain control. The objective was to evaluate the association of a protocol on opioid use in trauma patients and patient-reported pain scores. METHODS: This was a retrospective review of adult trauma patients admitted from 7/1-9/30/2018 to 7/1-9/30/2019 at an urban academic level 1 trauma center. The MMPP consisted of scheduled nonopioid medications implemented on July 1, 2019. Patients were stratified by level of care upon admission, intensive care unit (ICU) or floor, and by injury severity score (ISS) (ISS < 16 or ISS ≥ 16). Pain scores, opioid, and nonopioid analgesic medication use were compared for the hospital stay or first 30 d. RESULTS: Seven hundred ninety eight patients were included with a mean age of 54 ± 22 y and 511 (64.0%) were men. Demographic and clinical characteristics between those in the pre-MMP (n = 404) and post-MMPP (n = 394) groups were not different. The average pain scores were not different between the two groups (3.7 versus 3.8, P = 0.44), but patients in the post-MMPP group received 36% less morphine milliequivalents (109.6 versus 70; P < 0.0001). The MMPP had the largest effect on patients admitted to the ICU regardless of injury severity. ICU patients with ISS ≥ 16 had the greatest reduction in morphine milliequivalents (174.6 versus 84.4; P < 0.0001). The use of nonopioid analgesics was significantly increased in all groups. CONCLUSIONS: A MMPP is associated with a reduction of opioids and increase in nonopioid analgesics with no difference in patient-reported pain scores.

Gender-based differences in brachial artery flow-mediated vasodilation as an indicator of significant coronary artery disease.

Ultrasound of the brachial artery is widely used to assess endothelial function, but whether brachial artery flow-mediated vasodilation (FMD) differs between women and men who have coronary artery disease (CAD) has not been examined. To investigate gender-based differences in brachial artery FMD as an indicator of significant CAD, FMD was measured in women and men outpatients who had CAD (coronary stenosis >50%, n = 64) and those who did not have significant CAD (n = 145). FMD in women who had CAD (n = 33, 9.1 +/- 0.8%) was higher than that in similarly aged men who had CAD (n = 31, 6.4 +/- 0.5%; p = 0.008). The FMD cutpoint that maximized sensitivity with least effect on specificity for screening CAD was 15% (91% sensitivity, 25% specificity) in women but 10% (90% sensitivity, 43% specificity) in men. If the cutpoint as defined in men were used to evaluate women, brachial artery ultrasound would fail to diagnose 42% of women who do not have significant CAD; thus, a higher FMD cutpoint is required to optimize the sensitivity of FMD for identifying women who have significant CAD compared with similarly aged men. In studies using FMD to evaluate cardiovascular risk, different standards should be applied for women and men.
