An exploration on the relationship between traffic flow and the rate of surgical site infections: A literature review.

Surgical site infections are the second most frequent type of health-care associated infections in Europe and America. Public Health England's data on 139,691 operations at 209 hospitals reported 1,635 surgical site infections between April 2012 and March 2017. Patients with a surgical site infection are twice as likely to die, five times more likely to be readmitted after discharge and are likely to have a prolonged hospitalization. Therefore, it is still a significant issue that professionals need to help reduce. This literature review looks at ventilation within theatres and how traffic flow can affect the air flow and if it can increase the incidence rates of surgical site infections. Recommendations of strategies are made to help reduce traffic flow within operating theatres.
