Abstract

Objective: The purpose of this study was to identify objective measures that predict surgeon nontechnical skills (NTS) during surgery. Background: NTS are cognitive and social skills that impact operative performance and patient outcomes. Current methods for NTS assessment in surgery rely on observation-based tools to rate intraoperative behavior. These tools are resource intensive (e.g., time for observation or manual labeling) to perform; therefore, more efficient approaches are needed. Method: Thirty-four robotic-assisted surgeries were observed. Proximity sensors were placed on the surgical team and voice recorders were placed on the surgeon. Surgeon NTS was assessed by trained observers using the NonTechnical Skills for Surgeons (NOTSS) tool. NTS behavior metrics from the sensors included communication, speech, and proximity features. The metrics were used to develop mixed effect models to predict NOTSS score and in machine learning classifiers to distinguish between exemplar NTS scores (highest NOTSS score) and non-exemplar scores. Results: NTS metrics were collected from 16 nurses, 12 assistants, 11 anesthesiologists, and four surgeons. Nineteen behavior features and overall NOTSS score were significantly correlated (12 communication features, two speech features, five proximity features). The random forest classifier achieved the highest accuracy of 70% (80% F1 score) to predict exemplar NTS score. Conclusion: Sensor-based measures of communication, speech, and proximity can potentially predict NOTSS scores of surgeons during robotic-assisted surgery. These sensing-based approaches can be utilized for further reducing resource costs of NTS and team performance assessment in surgical environments. Application: Sensor-based assessment of operative teams' behaviors can lead to objective, real-time NTS measurement. [ABSTRACT FROM AUTHOR]

Abstract

Background: Weight regain (WR) post bariatric surgery affects almost 20% of patients. It has been theorized that a complex interplay between physiologic adaptations and epigenetic mechanisms promotes WR in obesity, however, reliable predictors have not been identified. Our study examines the relationship between early postoperative weight loss (WL), nadir weight (NW), and WR following laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG). Methods: A retrospective review of prospectively collected data was conducted for LRYGB or LSG patients from 2012 to 2016. Demographics, preoperative BMI, procedure type, and postoperative weight at 6, 12, 24, 36, and 48 months were recorded. WR was defined as > 20% increase from NW. Univariate and multivariate linear and logistic regression models were used to determine the association between early postoperative WL with NW and WR at 4 years. Results: Thousand twenty-six adults were included (76.8% female, mean age 44.9 ± 11.9 years, preoperative BMI 46.1 ± 8); 74.6% had LRYGB and 25.3% had LSG. Multivariable linear regression models showed that greater WL was associated with lower NW at 6 months (Coef − 2.16; 95% CI − 2.51, − 1.81), 1 year (Coef − 2.33; 95% CI − 2.58, − 2.08), 2 years (Coef − 2.04; 95% CI − 2.25, − 1.83), 3 years (Coef − 1.95; 95% CI − 2.14, − 1.76), and 4 years (Coef − 1.89; 95% CI − 2.10, − 1.68), p ≤ 0.001. WR was independently associated with increased WL between 6 months and 1 year (Coef 1.59; 95% CI 1.05,2.14; p ≤ 0.001) and at 1 year (Coef 1.24; 95% CI 0.84,1.63;p ≤ 0.001) postoperatively. The multivariable logistic regression model showed significantly increased risk of WR at 4 years for patients with greater WL at 6 months (OR 1.20, 95% CI 1.08,1.33; p = 0.001) and 1 year (OR 1.14; 95% CI 1.06,1.23; p ≤ 0.001). Conclusion: Our findings demonstrate that higher WL at 6 and 12 months post bariatric surgery may be risk factors for WR at 4 years. Surgeons may need to follow patients with high early weight loss more closely and provide additional treatment options to maximize their long-term success. [ABSTRACT FROM AUTHOR]
