Interfacility Transfer of Pediatric Supracondylar Elbow Fractures: Transfer by Ambulance Shows No Advantage in Speed of Transfer or Prevention of Complications.
Journal of pediatric orthopedics · 2024-08-22 · Observational study
Abstract
BACKGROUND: The treatment of supracondylar humerus (SCH) fractures is increasingly centralized in tertiary centers. Interfacility transfer from other facilities may occur by ground ambulance or privately owned vehicle (POV). The objective of this study was to determine if interfacility transfer by POV is equivalent in transfer time and perioperative complications compared with ground ambulance. METHODS: This was a single-institution, retrospective study of SCH fractures with an intact pulse transferred by POV or ground ambulance. Transfer time points were collected to determine transfer time and speed. Associated injuries of ipsilateral fracture, skin at risk, and motor nerve palsy were recorded from orthopaedic documentation at the presentation. Insurance status and the Area Deprivation Index (ADI) were used as measures of socioeconomic disparity. RESULTS: 676 "urgent" Type III, IV, and flexion type SCH fractures and 167 "nonurgent" Type II SCH fractures were transferred by ambulance or POV. Open reduction was similar between urgent transfers transported by ambulance or POV (10% vs. 9%, P =0.344). There was no difference in transfer time ( P =0.391) or transfer speed ( P =0.416) between transfer groups. POV transfers were independently associated with no skin at risk (OR 2.1; 95% CI: 1.3-3.3, P =0.003), neurovascularly intact (OR 2.5; 95% CI: 1.4-4.4, P =0.001), and patients in the low (OR 1.9; 95% CI: 1.3-2.5, P =0.041) and moderate deprivation (OR 1.9; 95% CI: 1.1-3.5, P =0.034) compared with the high deprivation group. Medicaid insurance was associated with a lower odds ratio of private transport compared with commercial insurance (OR 0.54; 95% CI: 0.38-0.76, P =<0.001). CONCLUSIONS: Interfacility transfer of nonemergent SCH fractures by privately owned vehicles has a similar speed of transfer and perioperative complication rate to transfer by ground ambulance. Our findings allow the triaging of nonemergent SCH fractures for potential interfacility transfer by privately owned vehicles and bring attention to disparities in interfacility transfer methods. LEVEL OF EVIDENCE: Level III- Retrospective cohort study.
