Delayed Referral for Adult Traumatic Brachial Plexus Injuries

Abstract

The treatment of traumatic brachial plexus injury (BPI) is time-sensitive, and early nerve reconstruction is associated with superior nerve recovery. The objective of this study was to determine the rate of delayed referral to our centers for traumatic BPI, identifiable causes of delayed referral, and factors associated with delayed referral to a brachial plexus surgeon. We identified 84 patients with traumatic BPI referred to and evaluated by brachial plexus surgeons at 2 tertiary care referral centers from 2015 to 2019. Delayed referral was defined as more than 3 months from the date of injury to the date of initial evaluation by a brachial plexus surgeon. Causes of delayed referral were identified by review of the medical record. Bivariate analysis and multivariable logistic regression were used to identify factors associated with delayed referral. Mean age of the 84 patients in the study was 45 years; 69% were male. The most common pattern of BPI was global palsy (39%), followed by upper-trunk palsy (23%) and infraclavicular palsy (15%). Median time from injury to surgical evaluation was 2 months (interquartile range, 2-4 months). Thirty-seven patients had a delayed referral (44%). Multivariable logistic regression analysis showed that the hospital to which the patient was referred, Medicare insurance, and motorcycle accident as the mechanism of injury were associated with a delayed referral. Nearly half of traumatic BPI patients evaluated at 2 tertiary referral centers in a large metropolitan area in the United States presented in a delayed time frame. Both modifiable and nonmodifiable associations with delayed referral were identified. Patients with Medicare insurance had increased odds of delayed referral. Establishment of multidisciplinary BPI specialty centers, outreach to local and regional hospitals, and development of referral algorithms and pathways may improve timeliness of referrals.
