Identifying the fundamental structures and processes of care contributing to emergency general surgery quality using a mixed-methods Donabedian approach.
Acute Care Surgery (ACS) was developed as a structured, team-based approach to providing round-the-clock emergency general surgery (EGS) care for adult patients needing treatment for diseases such as cholecystitis, gastrointestinal perforation, and necrotizing fasciitis. In this study, the investigators sought to use a Donabedian approach to elucidate potential EGS structures and processes that might be associated with improved outcomes as an initial step in designing the optimal model of acute care surgery care for EGS patients.

Suitability of administrative claims databases for bariatric surgery research - is the glass half-full or half-empty?
The authors assessed the availability and validity of claims-based weight-related diagnosis codes among bariatric surgery patients who underwent adjusted gastric banding, Roux-en-Y gastric bypass, or sleeve gastrectomy. They found that claims-based weight-related diagnosis codes had excellent validity before and after bariatric surgical operation but suboptimal availability after operation. Claims databases can be used for bariatric surgery studies of non-weight-related effectiveness and safety outcomes that are well-captured.

Potential selection bias in observational studies comparing cervical disc arthroplasty to anterior cervical discectomy and fusion.
This retrospective cohort study looked at potential selection bias for spinal patients undergoing cervical disc arthroplasty (CDA) or anterior cervical discectomy and fusion (ACDF). A total of ACDF or CDA 290,419 procedures were identified in adults from 2004-2014 using ICD-9-CM diagnosis and procedure codes. The vast majority (98.2%) underwent ACDF. CDA patients were younger and healthier with a higher socioeconomic status than ACDF patients. CDA was also $574 more expensive in the fully specified model. There was no statistically significant difference in terms of complications between the two procedures.

Trajectory analysis for postoperative pain using electronic health records: a nonparametric method with robust linear regression and K-medians cluster analysis.
Postoperative pain scores are widely monitored and collected in the electronic health record, yet current methods fail to fully leverage the data with fast implementation. This article describes a trajectory analysis for postoperative pain using electronic health records. A robust linear regression was fitted to describe the association between the log-scaled pain score and time from discharge after total knee replacement.

Using a society database to evaluate a patient safety collaborative: the Cardiovascular Surgical Translational Study.
The authors assessed the utility of using external databases for quality improvement (QI) evaluations in the context of an innovative QI collaborative aimed to reduce three infections and improve patient safety across the cardiac surgery service line. They compared changes in each outcome between 15 intervention hospitals and 52 propensity score-matched hospitals, and found that improvement trends in several outcomes among the studied intervention hospitals were not statistically different from those in comparison hospitals. They conclude that using external databases may permit comparative effectiveness assessment by providing concurrent comparison groups, additional outcome measures, and longer follow-up.

Practical guide to surgical data sets: Medicare claims data.
In this article, the authors discuss pros and cons of Medicare data and explore commonly studied categories using this data (health policy evaluation, comparative effectiveness research, and outcome variations). They conclude that it is important to frame questions carefully and to use appropriate methods to ensure scientific rigor.

Defining a research agenda for patient-reported outcomes in surgery: using a Delphi survey of stakeholders.
The authors sought to create a research agenda to help determine future directions and advance cross-disciplinary collaboration on the use of patient-reported outcomes (PROs) in surgery. They concluded that the Patient-Reported Outcomes in Surgery Conference research agenda was created using a modified Delphi survey of stakeholders that will help researchers, surgeons, and funders identify crucial areas of future PROs research in surgery.

Comparison of comorbidity scores in predicting surgical outcomes.
The purpose of this study was to compare diagnosis-based and prescription-based comorbidity scores for predicting surgical outcomes. It concluded that the Centers for Medicare and Medicaid Services-Hierarchical Condition Categories had superior performance in predicting surgical outcomes. Prescription-based scores, alone or in addition to diagnosis-based scores, were not better than any diagnosis-based scoring system.
