Unless otherwise indicated, values listed are the frequency and percent.
value from either a Wilcoxon-Mann–Whitney test (continuous variables) or chi-square test (categorical variables).
least 1 unit of packed or whole red blood cells given from the surgical start time up to and including 72 hours postoperatively.
that occurs within 30 days after the operation and the infection involves only skin or subcutaneous tissue of the incision.
evidence of a documented open wound at the time of the principal operative procedure. An open wound is a breach in the integrity of the skin or separation of skin edges and includes open surgical wounds, with or without cellulitis or purulent exudate. This does not include osteomyelitis or localized abscesses.
that occurs within 30 days after the operation and the infection appears to be related to the operation and infection involved deep soft tissues (e.g., fascial and muscle layers) of the incision.
within 30 days was only available beginning in 2011; therefore, the percent provided reflects only the proportion of 2011-13 cases who were readmitted.
