Adjusted predictors of outcomes following index surgeries.

Note. S. aureus denotes Staphylococcus aureus. SNF denotes skilled nursing facility; Rehab denotes rehabilitation; ESRD denotes end-stage renal disease; NEast denotes northeast; MidAtlan denotes mid-Atlantic; COPD denotes chronic obstructive pulmonary disease, vs. denotes versus; c-statistic is 0.83; *denotes p<0.05; **denotes p<.01, ***denotes p<.001, ****denotes p<.0001, NS denotes not significant, n.a. denotes not applicable. Adjusted odds ratios were obtained from binary logistic multivariate regression performed on 219,958 patients with an index surgery, 5,077 of them with at least one hospitalization associated with S. aureus infection within 180 days from index surgery. A total of 24,020 patients died within 180-days from index surgery. SA infection refers to index admission only for length of stay, and any admission within 180 days of index admission in models for death.
