    Abstract Background During the COVID-19 pandemic, many physicians experienced burnout, underscoring the need to identify factors associated with this condition to develop effective prevention and treatment strategies. Objective To examine the relationship between physician burnout and individual factors, medical errors, medical leave and the work environment. Design A cross-sectional online survey conducted from November 2020 to December 2020. Participants Physicians registered with the Medical College of Chile. Setting Registered physicians working in Chile across primary, secondary and tertiary levels of healthcare. Primary outcomes Burnout was assessed using the Maslach Burnout Inventory for Human Services. Secondary outcomes Self-reported medical errors, medical leave and turnover. Independent variables Sociodemographic characteristics, personality factors, psychological well-being, mindfulness factors, self-compassion and work environment factors. Descriptive statistics, linear and logistic regressions and regression analyses with cross-validation using least absolute shrinkage and selection operator (LASSO) tests were applied. Results Of the 23 481 registered physicians, 795 (3.4%) completed the survey. The sample included 64.1% women, with a mean age of 37.7 years (SD=11.3). The prevalence of burnout syndrome was 20.4% based on strict criteria and 68.9% based on lax criteria. Burnout scores predicted days of medical leave (ß=0.086, p<0.01), turnover (ß=0.012, p<0.05) and perceived medical errors (ß=0.009, p<0.001). In contrast, burnout was inversely correlated with age (ß=−0.125, p<0.001), agreeableness as a personality trait (ß=−0.107, p<0.001), psychological well-being (ß=−0.248, p<0.001) and the mindfulness factor awareness (ß=−0.145, p<0.001). In the work environment, time pressure (ß=0.167, p<0.001) was positively associated with burnout among others. Conclusion Younger physicians may be prioritised for individual-level interventions, while addressing time pressure at the organisational level could help prevent burnout. However, longitudinal studies are needed to clarify the directionality of relationships with psychological factors.

    <jats:title>Abstract</jats:title><jats:p>Early results with robotic-arm-assisted total knee arthroplasty (TKA) are encouraging; nevertheless, literature might be unrepresentative, as it comes mostly from American, European, and Asian countries. There is limited experience and no comparative clinical reports in Latin America, a region of mainly low- and middle-income countries with limited access to these promising technologies. This study aims to compare the early postoperative results of the first Latin American experience with robotic-arm-assisted TKA versus conventional TKA. A cohort study was performed, including 181 consecutive patients (195 knees) with advanced symptomatic knee osteoarthritis (OA) undergoing primary TKA between March 2016 and October 2019. The cohort included 111 consecutive patients (123 knees) undergoing conventional TKA, followed by 70 consecutive patients (72 knees) undergoing robotic-arm-assisted TKA. The same surgical team (surgeon 1 and surgeon 2) performed all procedures. Patients with previous osteotomy, posttraumatic OA, and revision components were not considered. The same anesthetic and rehabilitation protocol was followed. The investigated clinical outcomes (for the first 60 postoperative days) were: surgical tourniquet time, time to home discharge, time to ambulation, postoperative daily pain (Visual Analog Scale), opioid use, range of motion, blood loss, complications, and postoperative mechanical axis. The early clinical postoperative results of this first Latin American comparative experience of robotic-arm-assisted TKA versus conventional technique showed lower opioids requirements and faster functional recovery of ambulation in those patients operated with the robotic system; nevertheless, surgical times were higher, without differences in total postoperative complications and other clinical outcomes.</jats:p>

The S‐KOOS, JR resulted in 100% acceptability when answered. There were no ceiling or floor effects detected. The Cronbach’s α for the S‐KOOS, JR was 0.927 and its MEMC was 0.852 (CI 95% 0.636–1.078).
