Efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) for the treatment of acute pain after orthopedic trauma: a practice management guideline from the Eastern Association for the Surgery of Trauma and the Orthopedic Trauma Association.

Objectives: Fracture is a common injury after a traumatic event. The efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) to treat acute pain related to fractures is not well established. Methods: Clinically relevant questions were determined regarding NSAID use in the setting of trauma-induced fractures with clearly defined patient populations, interventions, comparisons and appropriately selected outcomes (PICO). These questions centered around efficacy (pain control, reduction in opioid use) and safety (non-union, kidney injury). A systematic review including literature search and meta-analysis was performed, and the quality of evidence was graded per the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. The working group reached consensus on the final evidence-based recommendations. Results: A total of 19 studies were identified for analysis. Not all outcomes identified as critically important were reported in all studies, and the outcome of pain control was too heterogenous to perform a meta-analysis. Nine studies reported on non-union (three randomized control trials), six of which reported no association with NSAIDs. The overall incidence of non-union in patients receiving NSAIDs compared with patients not receiving NSAIDs was 2.99% and 2.19% (p=0.04), respectively. Of studies reporting on pain control and reduction of opioids, the use of NSAIDs reduced pain and the need for opioids after traumatic fracture. One study reported on the outcome of acute kidney injury and found no association with NSAID use. Conclusions: In patients with traumatic fractures, NSAIDs appear to reduce post-trauma pain, reduce the need for opioids and have a small effect on non-union. We conditionally recommend the use of NSAIDs in patients suffering from traumatic fractures as the benefit appears to outweigh the small potential risks.

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.

Traumatic abdominal wall injuries-a primer for radiologists.

Traumatic abdominal wall injuries encompass a broad clinical and radiological spectrum and are identified in approximately 9% of blunt trauma patients. The most severe form of abdominal wall injury-a traumatic abdominal wall hernia-is seen in less than 1.5% of blunt abdominal trauma patients. However, the incidence of concurrent intra-abdominal injuries in these patients is high and can result in significant morbidity and mortality. Although the diagnosis of abdominal wall injuries is typically straight forward on CT, associated injuries may distract the interpreting radiologist in more subtle cases. Thus, it is important for the radiologist to identify abdominal wall injuries and their associated injuries on admission CT, as these injuries typically require surgical correction early in the course of their management. Untreated abdominal wall injuries subject the patient to increased risk of delayed bowel incarceration and strangulation. Therefore, it is important for the radiologist to be knowledgeable of injuries to the abdominal wall and commonly associated injuries to provide optimal patient triage and expedite management.

Opioid exposure after injury in United States trauma centers: A prospective, multicenter observational study.

BACKGROUND: Efforts to reduce opioid use in trauma patients are currently hampered by an incomplete understanding of the baseline opioid exposure and variation in United States. The purpose of this project was to obtain a global estimate of opioid exposure following injury and to quantify the variability of opioid exposure between and within United States trauma centers. STUDY DESIGN: Prospective observational study was performed to calculate opioid exposure by converting all sources of opioids to oral morphine milligram equivalents (MMEs). To estimate variation, an intraclass correlation was calculated from a multilevel generalized linear model adjusting for the a priori selected variables Injury Severity Score and prior opioid use. RESULTS: The centers enrolled 1,731 patients. The median opioid exposure among all sites was 45 MMEs per day, equivalent to 30 mg of oxycodone or 45 mg of hydrocodone per day. Variation in opioid exposure was identified both between and within trauma centers with the vast majority of variation (93%) occurring within trauma centers. Opioid exposure increased with injury severity, in male patients, and patients suffering penetrating trauma. CONCLUSION: The overall median opioid exposure was 45 MMEs per day. Despite significant differences in opioid exposure between trauma centers, the majority of variation was actually within centers. This suggests that efforts to minimize opioid exposure after injury should focus within trauma centers and not on high-level efforts to affect all trauma centers. LEVEL OF EVIDENCE: Epidemiological, level III.

Accurate risk stratification for development of organ/space surgical site infections after emergent trauma laparotomy.

BACKGROUND: Organ/space surgical site infection (OS-SSI) develops frequently after trauma laparotomies and is associated with significant morbidity. No valid model exists to accurately risk-stratify the probability of OS-SSI development after emergent laparotomy. Risk stratification for OS-SSI in these patients could guide promising, but unproven, interventions for OS-SSI prevention, such as more frequent dosing of intraoperative antibiotics or direct peritoneal resuscitation. We hypothesize that in trauma patients who undergo emergent laparotomy, probability of OS-SSI can be accurately estimated using patient data available during the index operation. METHODS: Retrospective review was performed on a prospectively maintained database of emergent trauma laparotomies from 2011 to 2016. Patient demographics and risk factors for OS-SSI were collected. We performed Bayesian multilevel logistic regression to develop the model based on a 70% training sample. Evaluation of model fit using area under the curve was performed on a 30% test sample. The Bayesian approach allowed the model to address clustering of patients within physician while implementing regularization to improve predictive performance on test data. RESULTS: One hundred seventy-two (15%) of 1,171 patients who underwent laparotomy developed OS-SSI. Variables thought to affect development of surgical site infections and were available to the surgeon near the conclusion of the trauma laparotomy were included in the model. Two variables that contributed most to OS-SSIs were damage-control laparotomy and colon resection. The area under the curve of the predictive model validated on the test sample was 0.78 (95% confidence interval, 0.71-0.85). CONCLUSION: Using a combination of factors available to surgeons before the end of an emergent laparotomy, the probability of OS-SSI could be accurately estimated using this retrospective cohort. A Web-based calculator is under design to allow the real-time estimation of probability of OS-SSI intraoperatively. Prospective validation of its generalizability to other trauma cohorts and of its utility at the point of care is required. LEVEL OF EVIDENCE: Prognostic study, level IV.
