Effects of preoperative surgeon warm-up in video-assisted thoracoscopic surgery lobectomy. BMC Surg 2024; 24:11. [PMID: 38172798 PMCID: PMC10765877 DOI: 10.1186/s12893-023-02300-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 12/22/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND In various surgical specialties, preoperative surgical warm-up has been demonstrated to affect a surgeon's performance and the perioperative outcomes for patients. However, the influence of warm-up activities on video-assisted thoracoscopic surgery lobectomy (VATSL) remains largely unexplored. This study aims to investigate the potential effects of preoperative surgical warm-up on VATSL. METHODS A cohort of 364 patients diagnosed with lung cancer through pathology and undergoing VATSL at the Thoracic Surgery Department of Xuzhou Medical University from January 2018 to September 2022 were included. Patients were categorized into two groups: the warm-up group, comprising 172 patients undergoing their first VATSL of the day, and the warm-up effect group, consisting of 192 patients undergoing their second VATSL on the same day. Propensity score matching was employed to compare operation times and postoperative complications between the two groups, resulting in 159 matched cases in each group. RESULTS There were no statistically significant differences in operation time (154.5 ± 54.9 vs. 147.2 ± 54.4 min, p = 0.239) and postoperative complications (including pulmonary infection, atelectasis, long-term pulmonary air leakage requiring incision suture in the operating room, and postoperative pleural effusion) (14:22 cases, p = 0.157) between the warm-up and warm-up effect groups. CONCLUSION The findings suggest that preoperative surgical warm-up does not significantly affect the perioperative outcomes of VATSL.

Abstract
ABSTRACT Although just-in-time training (JIT) is increasingly used in simulation-based health professions education, its impact on learning, performance, and patient outcomes remains uncertain. The aim of this study was to determine whether JIT simulation training leads to improved learning and performance outcomes. We included randomized or nonrandomized interventional studies assessing the impact of JIT simulation training (training conducted in temporal or spatial proximity to performance) on learning outcomes among health professionals (trainees or practitioners). Of 4077 citations screened, 28 studies were eligible for inclusion. Just-in-time training simulation training has been evaluated for a variety of medical, resuscitation, and surgical procedures. Most JIT simulation training occurred immediately before procedures and lasted between 5 and 30 minutes. Despite the very low certainty of evidence, this systematic review suggests JIT simulation training can improve learning and performance outcomes, in particular time to complete skills. There remains limited data on better patient outcomes and collateral educational effects.

Just-in-time clinical video review improves successful placement of Sengstaken-Blakemore tube by emergency medicine resident physicians: A randomized control simulation-based study. AEM EDUCATION AND TRAINING 2021; 5:e10573. [PMID: 34124519 PMCID: PMC8171783 DOI: 10.1002/aet2.10573] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 12/24/2020] [Accepted: 01/04/2021] [Indexed: 06/12/2023]
Abstract
OBJECTIVE Successful completion of life-saving procedures may benefit from a concise just-in-time (JIT) intervention. Video is an optimal medium for JIT training, but currently available video-based references are not optimized for a JIT format, especially in time-pressured situations prior to high-risk clinical contexts. We aimed to create and evaluate the efficacy of a brief video review of emergent Sengstaken-Blakemore tube (SBT) insertion for acutely decompensating variceal hemorrhage when used just prior to clinical performance in a simulated setting. METHODS We created a less than 3-minute audio-optional JIT training video on SBT insertion. We recruited emergency medicine resident physicians to participate in a simulation scenario in which they had to quickly place an SBT. Participants were randomized to either a 3-minute procedure review by any media they chose (control) or review of the JIT video (intervention). Performance on a checklist created by a multidisciplinary group of SBT experts (passing score > 18 and maximum = 28) served as the primary outcome. We analyzed performance in checklist scores controlling level of training through a one-way analysis of covariance (ANCOVA). We analyzed rates of passing scores via a chi-square analysis. RESULTS We randomized 32 participants to media review (control) or JIT video (intervention). The intervention group had an overall mean (±SD) performance of 19.8 (±9.0) and the control group had a mean (±SD) score of 6.6 (±7.4). After adjusting for postgraduate year, we found a significant difference in final checklist scores between the two groups (mean difference = 12.8, 95% confidence interval [CI] = 7.6 to 18.0). Percentages of participants reaching a minimum passing score were two of 16 (12.5%) in the control group and 10 of 16 (62.5%) in the intervention group (odds ratio = 11.7, 95% CI = 9.9 to 13.5). Cohen's kappa indicated substantial agreement (κ = 0.714) between reviewer scores. CONCLUSIONS A readily available, focused, audio-optional JIT video increased performance for SBT insertion in a simulated setting. Future work may include testing of this format for more commonly performed emergency procedures and determination of effect on bedside performance in the clinical setting.

Abstract
Interest is growing within the urological surgery community for objective assessments of technical skill. Surgical video review relies on the use of objective assessment tools to evaluate both global and procedure-specific skill. These evaluations provide structured feedback to surgeons with the aim of improving technique, which has been associated with patient outcomes. Currently, skill assessments can be performed by using expert peer-review, crowdsourcing or computer-based methods. Given the relationship between skill and patient outcomes, surgeons might be required in the future to provide empirical evidence of their technical skill for certification, employment, credentialing and quality improvement. Interventions such as coaching and skills workshops incorporating video review might help surgeons improve their skill, with the ultimate goal of improving patient outcomes.

Validation of a new artificial model for simulated training of a laparoscopic vesicourethral anastomosis. Actas Urol Esp 2019; 43:348-354. [PMID: 31128874 DOI: 10.1016/j.acuro.2019.03.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 01/17/2019] [Accepted: 03/19/2019] [Indexed: 12/15/2022]
Abstract
OBJECTIVE The aim of this study is to prove the effectiveness of a low cost, artificial model for training of a laparoscopic urethrovesical anastomosis. MATERIALS AND METHODS This study included urologists who attended specialised courses on laparoscopic radical prostatectomy (LRP) held during the period 2015 to 2017. They were divided into 2 groups according to their previous experience in laparoscopic surgery. The tasks performed on the artificial simulator were prostate resection, "task 1", and urethrovesical anastomosis, "task 2". Once these exercises were completed, the study participants filled in an anonymous questionnaire regarding their demographic data and experience level in laparoscopic surgery (LS). In addition, they gave their opinions about the didactic capacity of the artificial organ and evaluated its usefulness as a tool for LRP training. To demonstrate face and content validity, the participants judged the texture, consistency, morphology and evaluated its similarity to the real organ. The assessment was made with a five-point Likert scale. RESULTS The students were divided into 2groups: 10 experts (Group E) and 12 novices (Group N). The only significant difference between the scores of novices and experts was regarding the inclusion of this tool in the training programs (Group E=5 points versus group N=4.4±0.59, P=.024). The experts' group rated all the items with higher scores than the novices' one. Regarding the general assessment of the simulation model, the novice participants gave an average score of 8.00±0.91 points out of 10, while the experts' group granted higher scores of 9.4±0,51. CONCLUSION This artificial model has shown to have an elevated face, content and construct validity, as well being an optimal didactic tool for training in the techniques of prostate resection and laparoscopic urethrovesical anastomosis.

Abstract
In gastrointestinal endoscopy, simulation-based training can help endoscopists acquire new skills and accelerate the learning curve. Simulation creates an ideal environment for trainees, where they can practice specific skills, perform cases at their own pace, and make mistakes with no risk to patients. Educators also benefit from the use of simulators, as they can structure training according to learner needs and focus solely on the trainee. Not all simulation-based training, however, is effective. To maximize benefits from this instructional modality, educators must be conscious of learners' needs, the potential benefits of training, and associated costs. Simulation should be integrated into training in a manner that is grounded in educational theory and empirical data. In this review, we focus on four best practices in simulation-based education: deliberate practice with mastery learning, feedback and debriefing, contextual learning, and innovative educational strategies. For each topic, we provide definitions, supporting evidence, and practical tips for implementation.

Abstract
PURPOSE OF REVIEW The purpose of the review is to update the reader on the current literature and recent studies evaluating the role of simulation and warm-up as part of surgical education and training, and maintenance of surgical skills. RECENT FINDINGS Laparoscopic and hysteroscopic simulation may improve psychomotor skills, particularly for early-stage learners. However, data are mixed as to whether simulation education is directly transferable to surgical skill. Data are insufficient to determine if simulation can improve clinical outcomes. Similarly, performance of surgical warm-up exercises can improve performance of novice and expert surgeons in a simulated environment, but the extent to which this is transferable to intraoperative performance is unknown. Surgical coaching, however, can facilitate improvements in performance that are directly reflected in operative outcomes. SUMMARY Simulation-based curricula may be a useful adjunct to residency training, whereas warm-up and surgical coaching may allow for maintenance of skill throughout a surgeon's career. These experiences may represent a strategy for maintaining quality and value in a lower volume surgical setting.

Abstract
PURPOSE OF REVIEW In order for the obstetric anesthesiologist to become a true perioperative / peripartum physician, a change in formative programs and certification process in anesthesia are needed. RECENT FINDINGS Anesthesia training programs are migrating to competency based medical education (CBME) worldwide. The traditional model of attending lectures, grand rounds, reading textbooks and journal papers should be complemented by virtual modalities such as massive open online courses or online teaching tools. The gold standard for assessment of procedural skills in anesthesia consists of a combination of global rating scales and previously validated checklists. Behaviors in the perioperative environment not directly related to the use of drugs, equipment or medical expertise are known as anesthesiologist nontechnical skills and trainees must learn and practice these skills; nontechnical skills can determine 50-80% of adverse events in high-risk professions, including medicine. Regular certification programs are also an important component of the new approach in medical education, in some high-income countries, the specialist anesthesiologist is undertaking regular certification but the impact of these programs on overall outcomes is still unknown. SUMMARY The obstetric population is becoming a higher risk population, requiring an obstetric anesthesiologist taking on the role of a perioperative / peripartum physician. It is essential that anesthesia training programs migrate to CBME through simulation-based curriculum that allow the achievement of nontechnical skills and team work competencies. It is also essential that regular certification for specialist anesthesiologists occur throughout their entire career.

Abstract
OBJECTIVES Warm-up is defined as a preparatory activity or procedure. Using case order as a surrogate for surgeon warm-up, first cases were compared with second or later cases for intraoperative complications, operative time, and length of stay (LOS) among women undergoing laparoscopic sacrocolpopexy. METHODS This is a retrospective study of laparoscopic sacrocolpopexies performed from 2009 through 2014 at a large academic center. Any surgery preceding laparoscopic sacrocolpopexy was considered a surrogate for surgeon warm-up. Logistic and linear regression analyses were used to identify predictors of complications, operative time, and LOS. RESULTS Of 480 procedures, 192 (40%) were first cases and 288 (60%) were second or later. Baseline characteristics were similar between groups. Intraoperative complication rate was not different between groups (6.3% vs 3.1%, P = 0.50) even after controlling for risk factors. Operative times were comparable on initial analysis (231.2 ± 55.2 vs 225.9 ± 51.2 minutes, P = 0.28l), but a small difference was detected after adjusting for confounding factors (body mass index, menopausal status, surgeon experience, intraoperative complications, and concomitant hysterectomy or midurethral sling; adjusted β = 8.44 minutes, P = 0.037). Length of stay was longer for first case patients (1.44 ± 0.67 vs 1.24 ± 0.50 days, P < 0.001) even after adjusting for age, medical comorbidities, operative time, conversion to laparotomy, ileus/bowel obstruction, and postoperative urinary retention (adjusted β = 0.183 days, P = 0.001) as well as after accounting for delayed start time of second or later cases. CONCLUSIONS Laparoscopic sacrocolpopexy performed first case of the day without preoperative surgeon warm-up conferred no significant increase in intraoperative complications. Second or later cases were associated with small decreases in operative time and in LOS.

Abstract
BACKGROUND Fibre-optic intubation (FOI) is an advanced technical skill, which anaesthesia residents must frequently perform under pressure. In surgical subspecialties, a virtual 'warm-up' has been used to prime a practitioner's skill set immediately before performance of challenging procedures. This study examined whether a virtual warm-up improved the performance of elective live patient FOI by anaesthesia residents. METHODS Clinical anaesthesia yr 1 and 2 (CA1 and CA2) residents were recruited to perform elective asleep oral FOI. Residents either underwent a 5 min, guided warm-up (using a bronchoscopy simulator) immediately before live FOI on patients with predicted normal airways or performed live FOI on similar patients without the warm-up. Subjects were timed performing FOI (from scope passing teeth to viewing the carina) and were graded on a 45-point skill scale by attending anaesthetists. After a washout period, all subjects were resampled as members of the opposite cohort. Multivariate analysis was performed to control for variations in previous FOI experience of the residents. RESULTS Thirty-three anaesthesia residents were recruited, of whom 22 were CA1 and 11 were CA2. Virtual warm-up conferred a 37% reduction in time for CA1s (mean 35.8 (SD 3.2) s vs. 57 (SD 3.2) s, P<0.0002) and a 26% decrease for CA2s (mean 23 (SD 1.7) s vs. 31 (SD 1.7) s, P=0.0118). Global skill score increased with warm-up by 4.8 points for CA1s (mean 32.8 (SD 1.2) vs. 37.6 (SD 1.2), P=0.0079) and 5.1 points for CA2s (37.7 (SD 1.1) vs. 42.8 (SD 1.1), P=0.0125). Crossover period and sequence did not show a statistically significant association with performance. CONCLUSIONS Virtual warm-up significantly improved performance by residents of FOI in live patients with normal airway anatomy, as measured both by speed and by a scaled evaluation of skills.

Abstract
BackgroundProviding simulation training directly before an actual clinical procedure—or ‘just-in-time’ (JiT)—is resource intensive, but could improve both provider performance and patient outcomes.ObjectivesTo assess the effects of JiT simulation training versus no JiT training on provider performance and patient complications following clinical procedures on patients.Study selectionWe searched MEDLINE, Cochrane Library, CINAHL, PsycINFO, ERIC, ClinicalTrials.gov, simulation journals indexes and references of included studies during October 2014 for randomised trials, non-randomised trials and before-after studies comparing JiT simulation training versus no JiT training among providers performing clinical procedures. Findings were synthesised qualitatively.FindingsOf 1805 records screened, 8 studies comprising 3540 procedures and 1969 providers were eligible. 5 involved surgical procedures; the other 3 included paediatric endotracheal intubations, central venous catheter dressing changes, or infant lumbar puncture. Methodological quality was high. Of the 8 studies evaluating provider performance, 5 favoured JiT simulation training with 18–48% relative improvement on validated clinical performance scales, 16–20% relative reduction in surgical time and 12% absolute reduction in corrective prompts during central venous catheter dressing changes; 3 studies were equivocal with no improvement in intubation success, lumbar puncture success or urological surgery clinical performance scores. 3 studies evaluated patient complications; 1 favoured JiT simulation training with 45% relative reduction in central line-associated blood stream infections; 2 studies found no differences following intubation or laparoscopic nephrectomy.ConclusionsJiT simulation training improves provider performance, but currently available literature does not demonstrate a reduction in patient complications.

Abstract
UNLABELLED PHENOMENON: Virtual reality simulators are the subject of several recent studies of skills training for robot-assisted surgery. Yet no consensus exists regarding what a core skill set comprises or how to measure skill performance. Defining a core skill set and relevant metrics would help surgical educators evaluate different simulators. APPROACH This review draws from published research to propose a core technical skill set for using the da Vinci surgeon console. Publications on three commercial simulators were used to evaluate the simulators' content addressing these skills and associated metrics. FINDINGS An analysis of published research suggests that a core technical skill set for operating the surgeon console includes bimanual wristed manipulation, camera control, master clutching to manage hand position, use of third instrument arm, activating energy sources, appropriate depth perception, and awareness of forces applied by instruments. Validity studies of three commercial virtual reality simulators for robot-assisted surgery suggest that all three have comparable content and metrics. However, none have comprehensive content and metrics for all core skills. INSIGHTS: Virtual reality simulation remains a promising tool to support skill training for robot-assisted surgery, yet existing commercial simulator content is inadequate for performing and assessing a comprehensive basic skill set. The results of this evaluation help identify opportunities and challenges that exist for future developments in virtual reality simulation for robot-assisted surgery. Specifically, the inclusion of educational experts in the development cycle alongside clinical and technological experts is recommended.

Abstract
OBJECTIVE The objective of this trial was to assess which type of warm-up has the highest effect on virtual reality (VR) laparoscopy performance. The following warm-up strategies were applied: a hands-on exercise (group 1), a cognitive exercise (group 2), and no warm-up (control, group 3). DESIGN This is a 3-arm randomized controlled trial. SETTING The trial was conducted at the department of surgery of the University Hospital Basel in Switzerland. PARTICIPANTS A total of 94 participants, all laypersons without any surgical or VR experience, completed the study. RESULTS A total of 96 participants were randomized, 31 to group 1, 31 to group 2, and 32 to group 3. There were 2 postrandomization exclusions. In the multivariate analysis, we found no evidence that the intervention had an effect on VR performance as represented by 6 calculated subscores of accuracy, time, and path length for (1) camera manipulation and (2) hand-eye coordination combined with 2-handed maneuvers (p = 0.795). Neither the comparison of the average of the intervention groups (groups 1 and 2) vs control (group 3) nor the pairwise comparisons revealed any significant differences in VR performance, neither multivariate nor univariate. VR performance improved with increasing performance score in the cognitive exercise warm-up (iPad 3D puzzle) for accuracy, time, and path length in the camera navigation task. CONCLUSIONS We were unable to show an effect of the 2 tested warm-up strategies on VR performance in laypersons. We are currently designing a follow-up study including surgeons rather than laypersons with a longer warm-up exercise, which is more closely related to the final task.

Abstract
OBJECTIVES Since its introduction, there have been many refinements in the technique and implementation of robotic-assisted radical prostatectomy (RARP). However, it is unclear whether operative outcomes are influenced by surgical case order. We evaluated the effect of case order on perioperative outcomes for RARP within a large health maintenance organization. MATERIALS AND METHODS We conducted a retrospective review of RARP cases performed at our institution from September 2008 to December 2010 using a single robotic platform. Case order was determined from surgical schedules each day and surgeries were grouped into 1(st), 2(nd) and 3(rd) round cases. Fourth round cases (n = 1) were excluded from analysis. We compared clinicopathological variables including operative time, estimated blood loss (EBL), surgical margin rates and complication rates between groups. RESULTS Of the 1018 RARP cases in this cohort, 476 (47%) were performed as 1(st) round cases, 398 (39%) 2(nd) round cases and 144 (14%) 3(rd) round cases by a total of 18 surgeons. Mean operative time was shorter as cases were performed later in the day (213 min vs. 209 min vs. 180 min, P < 0.0001) and similarly, EBL also decreased with surgical order (136 mL vs. 134 mL vs. 103 mL, P = 0.01). Transfusion rates, surgical margin rates and complication rates did not significantly differ between groups. Patients undergoing RARP later in the day were much more likely to have a hospital stay of 2 or more days than earlier cases (10% vs. 11% vs. 32%, P = 0.01). CONCLUSIONS Surgical case order may influence perioperative outcomes for RARP with decreased operative times and increased length of hospital stay associated with later cases. These findings indicate that select perioperative factors may improve with ascending case order as the surgical team "warms up" during the day. In addition, 3(rd) round cases can increase hospital costs associated with increased lengths of hospital stay. Knowledge of these differences may assist in surgical planning to improve outcomes and limit costs.

Virtual reality robotic surgery warm-up improves task performance in a dry laboratory environment: a prospective randomized controlled study. J Am Coll Surg 2013; 216:1181-92. [PMID: 23583618 PMCID: PMC4082669 DOI: 10.1016/j.jamcollsurg.2013.02.012] [Citation(s) in RCA: 71] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2012] [Revised: 02/10/2013] [Accepted: 02/13/2013] [Indexed: 01/22/2023]
Abstract
BACKGROUND Preoperative simulation warm-up has been shown to improve performance and reduce errors in novice and experienced surgeons, yet existing studies have only investigated conventional laparoscopy. We hypothesized that a brief virtual reality (VR) robotic warm-up would enhance robotic task performance and reduce errors. STUDY DESIGN In a 2-center randomized trial, 51 residents and experienced minimally invasive surgery faculty in General Surgery, Urology, and Gynecology underwent a validated robotic surgery proficiency curriculum on a VR robotic simulator and on the da Vinci surgical robot (Intuitive Surgical Inc). Once they successfully achieved performance benchmarks, surgeons were randomized to either receive a 3- to 5-minute VR simulator warm-up or read a leisure book for 10 minutes before performing similar and dissimilar (intracorporeal suturing) robotic surgery tasks. The primary outcomes compared were task time, tool path length, economy of motion, technical, and cognitive errors. RESULTS Task time (-29.29 seconds, p = 0.001; 95% CI, -47.03 to -11.56), path length (-79.87 mm; p = 0.014; 95% CI, -144.48 to -15.25), and cognitive errors were reduced in the warm-up group compared with the control group for similar tasks. Global technical errors in intracorporeal suturing (0.32; p = 0.020; 95% CI, 0.06-0.59) were reduced after the dissimilar VR task. When surgeons were stratified by earlier robotic and laparoscopic clinical experience, the more experienced surgeons (n = 17) demonstrated significant improvements from warm-up in task time (-53.5 seconds; p = 0.001; 95% CI, -83.9 to -23.0) and economy of motion (0.63 mm/s; p = 0.007; 95% CI, 0.18-1.09), and improvement in these metrics was not statistically significantly appreciated in the less-experienced cohort (n = 34). CONCLUSIONS We observed significant performance improvement and error reduction rates among surgeons of varying experience after VR warm-up for basic robotic surgery tasks. In addition, the VR warm-up reduced errors on a more complex task (robotic suturing), suggesting the generalizability of the warm-up.
