Predictors for Direct to Operating Room Admission in Severe Trauma.

BACKGROUND: Protocols for expediting critical trauma patients directly from the helipad to the operating room tend to vary by center, rely heavily on physician gestalt, and lack supporting evidence. We evaluated a population of severely injured trauma patients with the aim of determining objective factors associated with the need for immediate surgical intervention. METHODS: All highest-activation trauma patients transported by air ambulance between 1/1/16 and 12/31/17 were enrolled retrospectively. Transfer, pediatric, isolated burn, and isolated head trauma patients were excluded. Patients who underwent emergency general surgery within 30 min of arrival without the aid of cross-sectional imaging were compared to the remainder of the cohort. RESULTS: Of the 863 patients who were enrolled, 85 (10%) spent less than 30 min in the emergency department (ED) before undergoing an emergency operation. The remaining 778 patients (90%) formed the comparison group. The ED ≤ 30 min group had a higher percentage of penetrating injuries, lower blood pressure, and was more likely to have a positive FAST exam. The "Direct to Operating Room" (DTOR) score is a predictive scoring system devised to identify patients most likely to benefit from bypassing the ED. The odds ratio of emergency operation within 30 min of hospital arrival increased by 2.71 (95% confidence interval 2.23-3.29; P < 0.001) for every 1-point increase in DTOR score. CONCLUSIONS: Trauma patients with profound hypotension or acidosis and positive FAST were more likely to require surgery within 30 min of hospital presentation. Use of a scoring system may allow early identification of these patients in the prehospital setting by nonphysician providers.

Efficacy of direct-to-operating room trauma resuscitation: a systematic review.

BACKGROUND: Hemorrhage control is a time-critical task, and recent studies have demonstrated that a shorter time to definitive care is positively associated with patient survival and functional outcomes. The concept of direct transport to the operating room was proposed in the 1960s to reduce treatment time. Some trauma centers have developed protocols for direct-to-operating room resuscitation (DOR) programs. Moreover, few studies have reported the clinical outcomes of DOR in patients with trauma; however, their clinical effect in improving the efficiency and quality of care remains unclear. In this systematic review, we aimed to consolidate all published studies reporting the effect of DOR on severe trauma and evaluate its utility. METHODS: The PubMed, EMBASE, and Cochrane databases were searched from inception to April 2023, to identify all articles published in English that reported the effect of direct-to-operating room trauma resuscitation for severe trauma. The articles were reviewed as references of interest. RESULTS: We reviewed six studies reporting the clinical effect of operating room trauma resuscitation. A total of 3232 patients were identified. Five studies compared the actual mortality with the predicted mortality using the trauma score and injury severity score, while one study compared mortality using propensity matching. Four studies reported that the actual survival rate for overall injuries was better than the predicted survival rate, whereas two studies reported no difference. Some studies performed subgroup analyses. Two studies showed that the survival rate for penetrating injuries was better than the predicted survival rate, and one showed that the survival rate for blunt injuries was better than the predicted survival rate. Five studies reported the time to surgical intervention, which was within 30 min. Two studies time-compared surgical intervention, which was shorter in patients who underwent DOR. CONCLUSION: Implementing DOR is likely to have a beneficial effect on mortality and can facilitate rapid intervention in patients with severe shock. Future studies, possibly clinical trials, are needed to ensure a proper comparison of the efficiency.
