Pattern of Maxillofacial Trauma and Associated Factors in Traffic Accident Victims

Maxillofacial trauma (MFT) due to road traffic accidents are responsible for part of care provided at trauma centers.This research aimed to analyze the pattern of MFTs and associated factors in victims of road traffic accidents.A total of 873 medical records of patients with MFTs in 2 reference hospitals for trauma in Northeastern Brazil during the period from January 2011 to December 2018 were analyzed. Data were included in the Tweedie multiple regression analysis to estimate the prevalence ratio (PR), with 95% confidence interval (95%CI) and P < 0.05.Motorcycle accidents were the most prevalent (76.4%). Higher hospital costs were the result of patients victims of motorcycle accidents (PR = 1.56; 95%CI = 1.29-1.88; P < 0.001), diagnosed with mandible fracture (PR = 1.41; 95%CI = 1.07-1.86; P = 0.001) who had consumed alcoholic beverages (PR = 1.12; 95%CI = 1.00-1.25; P = 0.04) and did not use personal protective equipment (PPE) (PR = 1.29; 95%CI = 1.10-1.50; P = 0.001). Patients victims of motorcycle accidents remained in hospital longer than other etiologies (PR = 1.47; 95%CI = 1.23-1.76; P < 0.001). The consumption of alcoholic beverages resulted in more severe MFTs (PR = 2.05; 95%CI = 1.34-3.14; P = 0.001).Victims of motorcycle accidents remained hospitalized longer and resulted in higher hospital costs compared to other etiologies. Alcohol consumption increases hospital costs and the severity of MFTs. Higher hospital costs were also observed in patients who did not use PPE. Strategies need to be adopted to understand associated factors in MFTs such as the reallocation of resources to fund, implement and improve services and the surveillance in roads and highways, as well as prevention programs aimed at this health problem.
