Observational Study
System Factors Affecting Patient Safety in the OR: An Analysis of Safety Threats and Resiliency.
The objective of this study is to determine the characteristics and frequency of intraoperative safety threats and resilience supports using a human factors measurement tool. ⋯ Through a detailed human factors analysis of elective laparoscopic general surgery cases, this study provided a quantitative analysis of the existing safety threats and resilience supports in a modern endoscopic operating room.

The aim of this study was to understand variation in intraoperative and postoperative utilization for common general surgery procedures. ⋯ Surgeons are significant drivers of variation in surgical supply costs and procedure time, but much less so for postoperative LOS. Intraoperative and postoperative utilization profiles can be generated for individual surgeons and may be an important tool for reducing surgical costs.

Histologic subtypes of appendiceal cancer vary in their propensity for metastases to regional lymph nodes (LN). A predictive model would help direct subsequent surgical therapy. ⋯ The risk for nodal metastases in patients with appendiceal cancers can be quantified with reasonable accuracy using a predictive model incorporating patient age, sex, tumor histology, T-stage, and grade. This can help inform clinical decision making regarding the need for a right hemicolectomy following appendectomy.

Observational Study
Long-term Reintervention After Endovascular Abdominal Aortic Aneurysm Repair.
To describe the long-term reintervention rate after endovascular abdominal aortic aneurysm repair (EVR), and identify factors predicting reintervention. ⋯ All patients retain a high likelihood of reintervention after EVR, but clinical factors at the time of repair can predict those at highest risk.

The aim of this study was to identify independent predictors of hospital readmission for patients undergoing lobectomy for lung cancer. ⋯ Complications are the main driver of readmission after lobectomy for lung cancer. The highest risk was related to postoperative events requiring a procedure or medical therapy necessitating inpatient care.
