Identifying risk factors for suboptimal pelvic binder placement in major trauma.

This study aimed to identify the frequency of sub-optimal pelvic binder placement at a tertiary-level trauma centre, produce a reproducible, quantitative measure of pelvic binder fit, and identify risk factors for sub-optimal placement. We identified all consecutive patients who had a pelvic binder in place on arrival to the Royal Brisbane and Women's Hospital in Queensland, Australia from 2012-2016. The X-Rays were reviewed by two senior clinicians for position and measured for degree of displacement if not optimally placed between the greater and lesser trochanters. Risk factors for sub-optimal position of the binder were assessed using multiple logistic regression with inclusion of all variables that had a statistical association (to p<0.05) at the univariate analysis stage. Secondary assessment was conducted of patients who had undergone CT imaging for subcutaneous body fat distribution. In total, 496 X-Rays were assessed for pelvic binder fit, finding 43.5% sub-optimally placed. 39.7% binders were superior to the greater trochanter line and 3.8% inferiorly placed below the lesser trochanter line. The majority of the sub-optimally placed binders were within 60 mm of the ideal position. Female patients had a greater risk of sub-optimal binder placement compared to males (62.5% vs 37%). Increasing intertrochanteric height was found to be protective for ideal binder placement with an aOR 0.62 for each cm in increased height. There was no association with sub-optimal placement and age, sex, mechanism of trauma, injury severity score, number of body regions injured or Glasgow Coma Scale. There was strong kappa agreement between the X-Ray assessors for binder position assessment on the plain radiological imaging. Sub-optimal positioning of pelvic binders is common in our trauma population. This study has described the risk factors associated with higher rates of sub-optimal fit and provides a description of rapid radiological assessment for optimal fit for the bedside clinician caring for injured patients in the resuscitation room.
