baseline characteristics in laparoscopic simulator performance the impact of personal computer pc gaming experience and Visuospatial Ability
Surgery Open Science, 2020Co-Authors: Petra Renman, Ninos Oussi, Lars Enochsson, Konstantinos GeorgiouAbstract:Abstract Background Learning via simulators is under constant development, and it is important to further optimize simulator training curricula. This study investigates the impact of personal computer–gaming experience, Visuospatial skills, and repetitive training on laparoscopic simulator performance and specifically on the constituent parameters of the simulator score. Methods Forty-seven medical students completed 3 consecutive Minimally Invasive Surgical Trainer–Virtual Reality simulator trials. Previously, they performed a Visuospatial test and completed a questionnaire regarding baseline characteristics and personal computer–gaming experience. Linear regression was used to analyze the relationship between simulator performance and type of personal computer–gaming experience and Visuospatial Ability. Results During the first 2 Minimally Invasive Surgical Trainer–Virtual Reality simulation tasks, there was an association between personal computer–gaming experience and the coordination parameters of the score (eg, EconDiath task 1: P = .0047; EconDiath task 2: P = .0102; EconDiath task 3: P = .0836). The type of game category played seemed to have an impact on the coordination parameters (eg, EconDiath task 1–3 for sport games versus no-sport games: P = .01, P = .0013, and P = .01, respectively). In the first Minimally Invasive Surgical Trainer task, Visuospatial Ability correlated with Minimally Invasive Surgical Trainer simulator performance but was abolished with repetitive training (overall Minimally Invasive Surgical Trainer score task 1–3: P = .0122, P = .0991, and P = .3506, respectively). Sex-specific differences were noted initially but were abolished with training. Conclusion Sport games versus no-sport games demonstrated a significantly better Minimally Invasive Surgical Trainer performance. Furthermore, repetitive laparoscopic simulator training may compensate for a previous lack of personal computer–gaming experience, low Visuospatial Ability, and sex differences.

Simulator training and non-technical factors improve laparoscopic performance among OBGYN trainees.
Acta Obstetricia et Gynecologica Scandinavica, 2013Co-Authors: Liv Ahlborg, Leif Hedman, Li Felländer-tsai, Henry Nisell, Lars EnochssonAbstract:Objective To investigate how simulator training and non-technical factors affect laparoscopic performance among residents in obstetrics and gynecology. Design In this prospective study, trainees were randomized into three groups. The first group was allocated to proficiency-based training in the LapSimGyn® virtual reality simulator. The second group received additional structured mentorship during subsequent laparoscopies. The third group served as control group. At baseline an operation was performed and Visuospatial Ability, flow and self-efficacy were assessed. All groups subsequently performed three tubal occlusions. Self-efficacy and flow were assessed before and/or after each operation. Setting Simulator training was conducted at the Center for Advanced Medical Simulation and Training, Karolinska University Hospital. Sterilizations were performed at each trainee's home clinic. Population Twenty-eight trainees/residents from 21 hospitals in Sweden were included. Methods/main outcome measures Visuospatial Ability was tested by the Mental Rotation Test-A. Flow and self-efficacy were assessed by validated scales and questionnaires. Laparoscopic performance was measured as the duration of surgery. Visuospatial Ability, self-efficacy and flow were correlated to the laparoscopic performance using Spearman's correlations. Differences between groups were analyzed by the Mann–Whitney U-test. Results No differences across groups were detected at baseline. Self-efficacy scores before and flow scores after the third operation were significantly higher in the trained groups. Duration of surgery was significantly shorter in the trained groups. Flow and self-efficacy correlate positively with laparoscopic performance. Conclusions Simulator training and non-technical factors appear to improve the laparoscopic performance among trainees/residents in obstetrics and gynecology.

Non-technical factors influence laparoscopic simulator performance among OBGYN residents
Gynecological Surgery, 2012Co-Authors: Liv Ahlborg, Leif Hedman, Li Felländer-tsai, Carsten Rasmussen, Lars EnochssonAbstract:In addition to technical skills, nontechnical factors appear to influence surgical results. This study aims to analyze how Visuospatial Ability, self-efficacy, and flow are associated with simulated laparoscopic performance of residents in obstetrics and gynecology (OBGYN). In this cohort study, 28 residents in obstetrics and gynecology were tested for Visuospatial Ability and self-efficacy prior to simulator training. All participants subsequently conducted a basic set of tasks in the simulator. Self-efficacy, once again, and flow were assessed after training. Nineteen of the subjects then completed a 2-day course with identical simulator tasks, although now to a predefined credential level. Visuospatial Ability correlated with simulator performance in the technically most advanced simulator task in the basic set (“total time,” r = −0.40, p = 0.039). Flow correlated with: “right instrument pathway”(r = −0.40, p = 0.004) in that same task and with the 2-day overall training results (r = −0.56, p = 0.017). Self-efficacy correlated with the 2-day result (r = −0.56, p = 0.013) and significantly improved after training (p = 0.011). When constructing a curriculum for OBGYN residents, Visuospatial abilities and non-technical factors like flow and self-efficacy should be considered.

Objective assessment of Visuospatial and psychomotor Ability and flow of residents and senior endoscopists in simulated gastroscopy.
Surgical Endoscopy, 2006Co-Authors: Lars Enochsson, Leif Hedman, Bo Westman, Ann Kjellin, E. M. Ritter, Torsten Wredmark, Li Felländer-tsaiAbstract:Background Advanced medical simulators have predominantly been used to shorten the learning curve of endoscopy for medical students and young residents. Rarely have the effects of Visuospatial Ability and attitudes of intermediately experienced and experienced specialists been studied with regard to simulator training. The aim of this study was to assess the effects of Visuospatial Ability and attitude on performance in simulator training.

Visuospatial Ability as a Predictor of Novice Performance in Ultrasound-guided Regional Anesthesia.
Anesthesiology, 2015Co-Authors: Atif Shafqat, Eamonn Ferguson, Vishal Thanawala, Nigel M. Bedforth, Jonathan G. Hardman, R. MccahonAbstract:Background: Visuospatial Ability correlates positively with novice performance of simple laparoscopic tasks. The aims of this study were to identify if Visuospatial Ability could predict technical performance of an ultrasound–guided needle task by novice operators, and to describe how emotional state, intelligence and fear of failure impact on this. Methods: Sixty medical student volunteers enrolled in this observational study. We used an instructional video to standardize training for ultrasound-guided needle advancement in a turkey breast model and assessed volunteers’ performance independently by two assessors using composite error score (CES) and global rating scale (GRS). We assessed their ‘Visuospatial Ability’ with mental rotation test (MRT), group embedded figures test (GEFT) and Alice Heim group Ability (AH4) test. ‘Emotional state’ was judged with UWIST mood adjective checklist (UMACL) and fear of failure, and ‘general cognitive Ability’ with numerical reasoning test (NRT-20). Results: High CES scores (high error rate) were associated with low MRT scores (= −0.54; P

Results: High CES scores (high error rate) were associated with low MRT scores (= −0.54; P<0.001). Better GRS scores were associated with better MRT scores (= 0.47; P<0.001). Regarding emotions, GRS scores were low when anxiety levels were high (= −0.35; P= 0.005) and CES scores (errors) were low when individuals reported feeling vigorous and active (= −0.30; P= 0.01). Conclusions: MRT predicts novice performance of an ultrasound-guided needling task on a turkey model, and as a trait measure could be used as a tool to focus training resources on less able individuals. Anxiety adversely affects performance. Both may therefore prove useful in directing targeted training in USGRA.
