Notes.
Data source: The Nationwide Inpatient Sample, Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality.
SA-SSTIs hospitalizations were defined by any S. aureus infection codes concurrent with any skin and soft tissue infection codes. S. aureus hospitalizations were identified based on the following ICD-9-CM codes: S. aureus septicemia (0.38.11 and 038.12), S. aureus infection (041.11 and 041.12), and S. aureus pneumonia (482.41 and 482.42). Some ICD-9 codes for S. aureus infections were not available during the entire study period but added as new codes in October 2008 (i.e., 038.12, 041.12, and 482.42).
Skin and soft tissue infections were identified based on the following ICD-9-CM codes: carbuncle (680.xx), cellulitis and abscesses (681.xx and 682.xx), erysipelas (035.xx), impetigo (684.xx), mastitis (611.0.x and 771.5×), other (7048.x, pyoderma dermatitis (686.xx), pressure ulcer (707.xx), infection due to internal prosthetic device, implant, & graft (996.6×), Postoperative infection (998.5×), other infection; as complication of medical care (9993.x), or non-healing surgical wound (998.83).
SA-SSTIs hospitalizations were defined by any S. aureus infection codes concurrent with any skin and soft tissue infection codes.
