Observational cohort study.
Deep sternal wound infection (DSWI), also called postoperative or poststernotomy mediastinitis, is a severe complication to cardiac surgery, occurring in 1-4% of cardiac surgery patients. The infection is usually detected within 1-3 weeks postoperatively and both incidence and risk factors have been thoroughly investigated previously. Multiple studies found increased morbidity and mortality, determining DSWI as a serious complication. However, less is known about the long-term outcome of these patients, and risk factors have only been identified in small datasets.
Using the SWEDEHEART database, we include all patients who underwent cardiac surgery in Sweden from 1997 to 2015.
The aim is to identify risk factors and investigate the long-term outcome of deep sternal wound infection (DSWI) following cardiac surgery.
