Trauma

The coefficients for the Trauma and Injury Severity Score are derived from the Major Trauma Outcome Study (MTOS) in North America, so the applicability of the MTOS-Trauma and Injury Severity Score (TRISS) in different populations remains challenging. This study proposed an alternate TRISS model called National Trauma Database-TRISS, where the coefficients were derived from the National Trauma Database (NTrD) in Malaysia.

This study utilised data derived from the National Trauma Database in Malaysia with 70% of the cases being used to develop the NTrD-TRISS model, while model validation was conducted based on the remaining 30% of cases. Fractional polynomial method was applied to correct the non-linearity in the logit of Injury Severity Score (ISS) and New Injury Severity Score (NISS). The predictive validity of the NTrD-TRISS model was compared with the MTOS-TRISS model. The predictive validity of these models was further examined with ISS and NISS.

A total of 5857 major trauma cases reported to 13 trauma centres located throughout Malaysia for patients aged 16 and above were included in the study. The outcome prediction in trauma from NTrD-TRISS model was found to be more accurate compared to the MTOS-TRISS model.

This study has ascertained the applicability of the MTOS-TRISS model in Malaysia. The outcome prediction in trauma from the NTrD-TRISS was found to outperform the MTOS-TRISS model. Given the complex computational nature of ISS, the MTOS-TRISS and NTrD-TRISS models with NISS were recommended for future practical usage.

To determine the impact of a single episode of minor trauma during pregnancy on maternal and fetal outcomes.

This is a retrospective cohort study of pregnant women who experienced minor trauma at ≥24 weeks gestation between 2004 and 2014. The subjects who experienced minor trauma (minor trauma group) were matched by gestational age at the time of minor trauma, body mass index, and age to a cohort of women who did not experience trauma in pregnancy (control group). The primary obstetrical outcome was preterm delivery and the primary neonatal outcomes were APGAR scores and neonatal intensive care unit admission.

There were no significant differences between the two groups with respect to demographics or other risk factors for preterm delivery. Average gestational age at the time of delivery was 39 weeks regardless of whether a woman experienced minor trauma. Preterm delivery occurred more often in the control group (11.8% versus 7.9%, p = 0.0428) as did the rate of neonatal intensive care unit admissions (8.6% versus 5%, p = 0.0273). A subgroup analysis was performed excluding patients with a medically indicated delivery and there was no difference in the rate of preterm delivery (6.4% in the control group, 4% in the minor trauma group, p-value 0.9052). Among women with a spontaneous preterm delivery, the rates of preterm labor (3.0% control versus 2.0% minor trauma, p-value 0.75) and preterm premature rupture of membranes were found to be similar between the two groups (3.8% control versus 2.0% minor trauma PPROM, p-value 0.75).

One episode of minor trauma in pregnancy does not increase the risk for preterm delivery, premature rupture of membranes, or poor neonatal outcomes.

In El Salvador, over 32% of all deaths are due to trauma. However, El Salvador lacks any established standardized trauma response system to treat the most critical of Salvadoran patients. In an effort to improve trauma response in El Salvador, we assessed the impact of a trauma-specific skills training, which could improve trauma care in a setting where no formal trauma training exists.

We used a pre- and post-interventional design study to measure the critical actions performed during a trauma event, as well as the case-fatality rate, emergency ward-to-operating room time, and utilization of ultrasound. The intervention was a primary trauma care course taught to all study participants.

Eighteen providers were observed over a six-month period and 194 patient encounters (48 pre- and 146 post-intervention) were recorded. There was no significant difference in observed critical actions during major trauma between the pre-intervention and post-intervention periods. There was a significant improvement in ultrasound usage post-intervention (9.5% to 21.4%; p = 0.04).

The lack of behavior change observed following a two-day trauma training underscores the gap between physician knowledge and applied behavior change. This is a limited single center study, but further examination is necessary to determine the role of two-day training courses in the larger context of behavior change within a health system that has no formal post-graduate training in or defined algorithmic trauma care.

In 2014, the primary trauma care curriculum was delivered at a national trauma center in San Salvador, El Salvador. A quantitative analysis demonstrated that subsequent incorporation of primary trauma care algorithms did not occur. The purpose of this qualitative analysis is to explore why the delivery of the primary trauma care curriculum did not have a measurable effect on provider observance of primary trauma care algorithms.

Key informant interviews of primary trauma care instructors and students, trauma care observers, and hospital administrators involved in the delivery of the primary trauma care curriculum were conducted in February 2015. Interview transcripts were analyzed qualitatively using a grounded-theory approach and thematic analysis for insights and common themes.

Four common themes emerged to explain why adherence to primary trauma care algorithms did not improve: Primary Trauma Care course delivery problems, insufficient equipment, insufficient nurse training, and unsystematic team response.

Despite the delivery of the primary trauma care curriculum, adherence to the primary trauma care algorithms did not improve as a result of problems integral to the primary trauma care model—including the teach-the-teachers method of curriculum dissemination—as well as local conditions at this hospital. These findings suggest that an isolated educational intervention may not be successful unless the host institution is able to commit to the implementation of the educational material in an ongoing and comprehensive fashion.

Carotid injuries are infrequent following blunt traumatic injury but can have potentially devastating neurologic consequences. We present a case of a 31-year-old male with right common carotid transection after blunt trauma to the neck.

A 31-year-old male with no notable medical history presented as a trauma level one activation after riding his bicycle into an open car door causing a Zone II laceration of his right anterior neck. The patient was hemodynamically normal, had an intact airway and had no neurologic deficits on evaluation in the trauma bay. He underwent a computed tomography angiogram of his neck which revealed a focal dissection of the right common carotid artery causing a 70%–80% luminal narrowing suspicious for a grade II injury. The patient was taken to the operating room for exploration of his neck laceration. He was found to have a grade V injury with complete transection of the right common carotid artery through the intima and media with intact adventitia. The arterial injury was repaired with polytetrafluoroethylene interposition graft. Perioperatively, the patient was started on dual antiplatelet therapy. He recovered uneventfully without neurologic deficits.

Complete transection of the common carotid artery following blunt trauma is rarely reported. Based on a review of the literature regarding blunt carotid injuries, it is reasonable to repair such injuries with prosthetic graft followed by either systemic anticoagulation or dual antiplatelet therapy.
