The Prevalence of Blood-Borne Pathogens in Maxillofacial Trauma Patients

Blood-borne pathogen infections (BPIs), caused by the human immunodeficiency virus, hepatitis C and hepatitis B viruses pose an occupational hazard to healthcare workers. Facial trauma reconstruction surgeons may be at elevated risk because of routine use of sharps, and a higher than average incidence of BPIs in the trauma patient population.

The authors retrospectively reviewed health records of patients admitted to a level 1 trauma center with a facial fracture between January 2010 and December 2015. Patient demographics, medical history, mechanism of injury, type of fracture, and procedures performed were documented. The authors detemined the frequency of human immunodeficiency virus, hepatitis B, and hepatitis C diagnosis and utilized univariable/multivariable analyses to identify risk factors associated with infection in this population.

In total, 4608 consecutive patients were included. Infections were found in 4.8% (n = 219) of patients (human immunodeficiency virus 1.6%, hepatitis C 3.3%, hepatitis B 0.8%). 76.3% of BPI patients in this cohort were identified by medical history, while 23.7% were diagnosed by serology following initiation of care. 39.0% of all patients received surgical treatment during initial hospitalization, of whom 4.3% had a diagnosed BPI. History of intravenous drug use (odds ratio [OR] 6.79, P < 0.001), assault-related injury (OR 1.61, P = 0.003), positive toxicology screen (OR 1.56, P = 0.004), and male gender (OR 1.53, P = 0.037) were significantly associated with a BPI diagnosis.

Patients presenting with facial fractures commonly harbor a BPI. The benefit of early diagnosis and risk to surgical staff may justify routine screening for BPI in high risk facial trauma patients (male, assault-related injury, and history of intravenous drug use).
