Surgical Site Infections (SSIs) for Operative Procedures in California Hospitals

These datasets show surgical site infections (SSIs) reported by California hospitals to the California Department of Public Health (CDPH), Healthcare-Associated Infections (HAI) Program, via the Centers for Disease Control and Prevention National Healthcare Safety Network (NHSN), in accordance with Health and Safety Code (HSC) section 1288.55.

California hospitals track and report deep incisional and organ/space SSIs for adults and pediatric (<18 years of age) patients for 28 types of operative procedures: abdominal aortic aneurysm repair; abdominal hysterectomy; appendix surgery; bile duct, liver or pancreatic surgery, cardiac surgery; Cesarean section; colon surgery; coronary artery bypass graft with both chest and donor site incisions; coronary artery bypass graft with chest incision only*; exploratory abdominal surgery (laparotomy); gallbladder surgery; gastric surgery; heart transplant; hip prosthesis; kidney surgery; kidney transplant; knee prosthesis; laminectomy; liver transplant; open reduction of fracture; ovarian surgery; pacemaker surgery; rectal surgery; small bowel surgery; spinal fusion; spleen surgery; thoracic surgery; vaginal hysterectomy

The SSI data tables include information on the statewide and hospital-specific SSI incidence by operative procedure types, displaying procedure counts, number of infections observed (reported) and predicted. NHSN calculates the number of predicted infections using procedure-specific risk adjustment logistic regression models based on 2015 national baseline data and that accounts for particular patient-level factors and hospital characteristics found to be significant predictors of SSI incidence.

Detailed information about the variables included in each dataset are described in the accompanying data dictionaries for the year of interest.
