Characterizing surgical site infection signals in clinical notes.
Building off of previous work for automated and semi-automated surgical site infections (SSIs) detection using expert-derived "strong features" from clinical notes, researchers hypothesized that additional SSI phrases may be contained in clinical notes. They systematically characterized phrases and expressions associated with SSIs. While 83 percent of expert-derived original terms overlapped with new terms and modifiers, an additional 362 modifiers associated with both positive and negative SSI signals were identified.

Strategies for handling missing clinical data for automated surgical site infection detection from the electronic health record.
Proper handling of missing data is important for many secondary uses of electronic health record (EHR) data. Data imputation methods can be used to handle missing data, but their use for postoperative complication detection is unclear. Overall, models with missing data imputation almost always outperformed reference models without imputation that included only cases with complete data for detection of SSI overall achieving very good average area under the curve values.

Surgical site infections: volume-outcome relationship and year-to-year stability of performance rankings.
The researchers evaluated the volume-outcome relationship as well as the year-to-year stability of performance rankings following coronary artery bypass graft (CABG) surgery and hip arthroplasty. They concluded that aggregate surgical site infection risk is highest in hospitals with low annual procedure volumes. Even for higher volume hospitals, year-to-year random variation makes past experience an unreliable estimator of current performance.

Association between hospital characteristics and performance on the new hospital-acquired condition reduction program's surgical site infection measures.
This research letter evaluated the association between hospital characteristics and surgical site infection (SSI) measures. The authors found that hospitals with higher hospital quality summary scores were more frequently poor performers for SSI and had higher standardized infection ratios. Hospitals were more likely to be poor performers for colon SSI and hysterectomy SSI if they were a teaching hospital, safety-net hospital, or level I trauma center. Teaching hospitals were more likely to be poor performers for colorectal SSI, but the association was not as consistent for hysterectomy.

Postoperative infection in spine surgery: does the month matter?
The authors evaluated for seasonal variation of surgical site infection (SSI) following spine surgery in a network of nonteaching community hospitals. They found that the rate of SSI following fusion or spinal laminectomy/laminoplasty was higher during the summer in this network of community hospitals, most likely due to S. aureus rather than the July effect.
