The quality of electrodiagnostic tests for carpal tunnel syndrome: Implications for surgery, outcomes, and expenditures.
The quality of electrodiagnostic tests may influence treatment decisions, particularly regarding surgery, affecting health outcomes and health-care expenditures. In this study, the investigators evaluated test quality among 338 adults with workers' compensation claims for carpal tunnel syndrome. The investigators found that in simulations, suboptimal quality tests rendered surgery inappropriate for 99 of 309 patients (+32 percentage points). They also found that test quality was not associated with overall health, actual receipt of surgery, or expenditures.

Centralization of high-risk cancer surgery within existing hospital systems.
Centralization is often proposed as a strategy to improve the quality of certain high-risk health care services. In this study, the investigators evaluated the extent to which existing hospital systems centralize high-risk cancer surgery and whether centralization is associated with short-term clinical outcomes. The investigators concluded that greater centralization of complex cancer surgery within existing hospital systems was associated with better outcomes.

Fellow and attending surgeon operative notes are deficient in reporting established quality indicators for Roux-en-y gastric bypass: a preliminary retrospective analysis of operative dictation.
This retrospective analysis investigated the completeness of reporting documentation for Roux-en-Y Gastric Bypass (RYGB) surgery. A total of 40 bariatric fellow and 40 attending RYGB narrative reports were analyzed. Fellows had a mean completion rate of 66.4% compared to 61.5% for attendings. Fellows also did a better job of completing subsections, with the exception of closure details. This information is important to communicating operative events and can make an impact on patient safety and quality.

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.

Impact of patient safety indicators on readmission after abdominal aortic surgery.
This analysis evaluated whether Patient Safety Indicator (PSI) events after open surgical repair or endovascular aneurysm repair of abdominal aortic aneurysm (AAA) were associated with increased risk of readmission. The investigators concluded that Agency for Healthcare Quality and Research PSI events may be used to identify patients at the greatest risk for readmission after AAA repair. The risk for 30-day readmission was 71% higher when a PSI event occurred and was not associated with the type of repair.

Surgeon-reported complications vs AHRQ patient safety indicators: a comparison of two approaches to identifying adverse events.
This retrospective observational study compared 2 approaches for identifying adverse medical events: surgeon-reported complications vs AHRQ patient safety indicators (PSI). The study analyzed the degree to which these 2 processes captured PSI-defined events and reasons for exclusion by each process.

Hospital readmissions after surgery: how important are hospital and specialty factors?
Researchers hypothesized that hospital readmission rates for procedures within specialties were more strongly correlated than rates across specialties within the same hospital. However, they found that hospital readmission rates for orthopaedic, vascular, and general surgery were not correlated between specialties; within each of the 3 specialties, modest correlations were found between 2 procedures within 2 of these specialties.

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.

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.

Evaluating patient safety indicators in orthopedic surgery between Italy and the USA.
The authors compared patient safety in major orthopedic procedures between an orthopedic hospital in Italy and 26 Florida hospitals of similar size. AHRQ Patient Safety Indicators (PSIs) were used to identify inpatient adverse events (AEs). They found that US patients had lower adjusted odds of developing a PSI compared to Italy for pressure ulcers, hemorrhage or hematoma, and physiologic and metabolic derangement. while Italian patients had lower odds of pulmonary embolism/deep vein thrombosis compared to US patients.

Hospital variation in rates of acid-reducing medication use after laparoscopic sleeve gastrectomy.
This study assessed variation in hospital performance with laparoscopic sleeve gastrectomy using rates of acid-reducing medication use at postoperative 1 year. It concluded that across Michigan hospitals, rates of new acid-reducing medication use at 1 year after laparoscopic sleeve gastrectomy varied widely and did not correlate with traditional quality indicators.

Development and validation of an Agency for Healthcare Research and Quality indicator for mortality after congenital heart surgery harmonized with risk adjustment for congenital heart surgery (RACHS-1) methodology.
The National Quality Forum previously approved a quality indicator for mortality after congenital heart surgery developed by AHRQ. Several parameters of the validated Risk Adjustment for Congenital Heart Surgery (RACHS-1) method were included, but others differed. As part of the National Quality Forum endorsement maintenance process, developers were asked to harmonize the 2 methodologies.

Performance measures in neurosurgical patient care: differing applications of patient safety indicators.
The researchers sought to determine how Patient Safety Indicator (PSI) rates and their impact on other outcomes in patients undergoing cranial neurosurgery compared with other surgeries.. They found that procedure indication was strongly associated with PSI development. The neurosurgical population had significantly higher risk-adjusted ratios of most PSIs evaluated compared with other surgical patients. Development of a PSI was strongly associated with increased length of stay and hospital cost.

National evaluation of hospital readmission after pulmonary resection.
The study’s objectives were to (1) assess readmission rates and timing after pulmonary resection, (2) report the most common reasons for rehospitalization, and (3) identify risk factors for unplanned readmission after pulmonary resection. It found that experiencing a postoperative complication was strongly associated with unplanned readmission.
