This is a composite measure. For State Tables, appropriate timing of antibiotics includes receiving preventive antibiotics 1 hour before incision and discontinuing the antibiotics within 24 hours after surgery end time.
Data were downloaded in late April each year from: http://www.medicare.gov/Download/DownloadDB.asp.
Estimates are calculated using hospital-level scores.
