Limited resection versus lobectomy for older patients with early-stage lung cancer: Impact of histology.
The researchers used population-based data to assess the equivalency of limited resection versus lobectomy among older patients with stage IA invasive adenocarcinoma and squamous cell carcinoma less than 2 cm in size. They found generally that limited resection is not equivalent to lobectomy in older patients with invasive non–small-cell lung cancer, although segmentectomy may be equivalent in patients with adenocarcinoma.

Mortality associated with medical therapy versus elective colectomy in ulcerative colitis: a cohort study.
This study sought to determine whether patients with advanced ulcerative colitis (UC) treated with elective colectomy have improved survival compared with those treated with medical therapy. It found that elective colectomy was associated with improved survival compared with long-term medical therapy, although this result did not remain statistically significant in all sensitivity analyses.

Oral mechanical bowel preparation for colorectal surgery: systematic review and meta-analysis.
The purpose of this review was to synthesize the evidence on the comparative effectiveness and safety of oral mechanical bowel preparation versus no preparation or enema. It found weak evidence suggesting that oral mechanical bowel preparation has similar effectiveness compared with no preparation with respect to all-cause mortality, anastomotic leakage, wound infection, and peritonitis for patients undergoing elective surgery for colorectal cancer.

Rheumatoid arthritis does not increase risk of short-term adverse events after total knee arthroplasty: a retrospective case-control study.
More adverse events (AE) are reported after total knee arthroplasty (TKA) for patients with rheumatoid arthritis (RA) than for patients with osteoarthritis (OA). This study evaluates 6-month postoperative AE in a high-volume center in a contemporary RA cohort. It found that in a high-volume center, with high RA-specific experience, RA does not increase postoperative AE.

Cost-effectiveness of neoadjuvant chemotherapy versus primary surgery in elderly patients with advanced ovarian cancer.
This study investigated the cost-effectiveness of neoadjuvant chemotherapy (NAC) compared with that of standard primary debulking surgery. It concluded that NAC use before surgery has a favorable cost-effectiveness profile in the high-risk group alone at classic willingness-to-pay thresholds. Its use as a general first-line treatment in all patients is not supported.

Laparoscopic versus open Ladd's procedure for intestinal malrotation in adults.
This study was designed to investigate outcomes for adults undergoing laparoscopic surgery vs. open Ladd’s repair for malrotation. It found no significant differences in complication rates, need for re-operation, or symptom resolution. There was a statistically significant decrease in length of stay following laparoscopy compared to open surgery.

Integrating patient-reported outcomes into spine surgical care through visual dashboards: lessons learned from human-centered design.
The researchers share lessons learned from engaging health care professionals to inform design of visual dashboards, an emerging type of health information technology (HIT). Their work illustrates a range of engagement methods guided by human-centered principles and design recommendations for optimizing PRO Dashboards for patient care and quality improvement.

The Impact of the Multicenter Orthopaedic Outcomes Network (MOON) research on anterior cruciate ligament reconstruction and orthopaedic practice.
The Multicenter Orthopaedic Outcomes Network consortium was created in 2002 to enroll and longitudinally follow a large population cohort of anterior cruciate ligament reconstructions. The group has helped to establish a new benchmark for conducting multicenter, multisurgeon orthopaedic research. The changes in anterior cruciate ligament reconstruction practice resulting from the group include the use of autograft for high school, college, and competitive athletes.

The Spine Surgical Care and Outcomes Assessment Program (Spine SCOAP): a surgeon-led approach to quality and safety.
The researchers sought to identify variation in utilization, processes of care, and outcomes in spine surgery to improve statewide quality and safety. They found significant variability in the indications, process of care, and outcomes related to spine surgery. This variability indicates the need for continued surveillance initiatives and point to opportunities for quality improvement and research.

Quality of well-being outcomes in the National Emphysema Treatment Trial.
The purpose of this article is to report outcomes from the National Emphysema Treatment Trial (NETT) using an index that combines quality and quantity of life. Results showed that, compared with maximal medical therapy alone, patients undergoing maximal medical therapy plus lung volume reduction surgery experienced improved health-related quality of life and gained more quality-adjusted life years.

Does the use of neoadjuvant therapy for pancreatic adenocarcinoma increase postoperative morbidity and mortality rates?
The researchers used data from the NSQIP Pancreatectomy Demonstration Project (11/2011 to 12/2012) to identify patients with pancreatic adenocarcinoma who did and did not receive neoadjuvant therapy. They found that despite evidence for more extensive disease, patients receiving neoadjuvant therapy did not experience more complications. Neoadjuvant radiation was associated with lower pancreatic fistula rates.
