The 4 most frequently reported surgical categories by pathogen volume are shown. Supplemental tables are available in the 2015–2017 Adult Antimicrobial Resistance Report Online Supplement that show pathogen rankings separately for each NHSN operative procedure code (https://www.cdc.gov/nhsn/datastat/index.html).
Consists of all NHSN operative procedure codes and is not limited to the 4 surgical categories shown.
Appendix surgery, bile duct, liver, or pancreatic surgery, liver transplant, gallbladder surgery, colon surgery, gastric surgery, herniorrhaphy, small bowel surgery, spleen surgery, exploratory laparotomy, and rectal surgery.
Open reduction of fracture, hip prosthesis, knee prosthesis, limb amputation, spinal fusion/refusion, and laminectomy.
Cesarean section, abdominal hysterectomy, ovarian surgery, and vaginal hysterectomy.
Cardiac surgery, heart transplant, coronary artery bypass graft with chest incision with or without donor incision, pacemaker surgery, and thoracic surgery.
When analyzed on the genus level for all surgery types, Enterococcus ranks #2 and Candida ranks #9.
The group ‘Other Enterococcus spp’ combines enterococci identified to the species level, excluding E. faecium and E. faecalis, and enterococci for which the species was not reported.
