Integration and Sustainability of Electronic Surgical Logbooks in Sub-Saharan Africa.

BACKGROUND: Countries in Sub-Saharan Africa lack adequate surgical workforces to achieve safe and affordable care for their populations. The Global Surgery movement highlights the urgent need to address this situation. Interventions include not only financial, material and infrastructural support, but also collaborative information flow to support surgical training. In 2015, an electronic logbook was launched for surgical trainees across Sub-Saharan Africa. OBJECTIVES: To assess the integration and context sustainability of surgical e-logbooks in Sub-Saharan Africa. METHODS: In January 2019, a survey analysis of surgical trainees was employed using quantitative and qualitative methods. Participants (active trainees and recent fellows) completed an anonymous internet-based questionnaire evaluating end-user feedback, perceptions and self-reported compliance. Multi-point Likert Scale measures and free-text thematic analysis were used. RESULTS: 358 (68.19%) eligible individuals across 21 Sub-Saharan countries and seven surgical specialties voluntarily participated. The e-resource demonstrated integration into local curricula with the majority of users maintaining activity and reporting moderate-high compliance. Context appropriateness measures were high with 203 (69.76%) deeming it convenient to use. The principle obstacle to compliance was internet connectivity (74, 25.96%), while behavioural factors including supervisor engagement were implicated. The e-logbook demonstrated future sustainability with the majority (243, 78.14%) of participants intent on maintaining usage beyond completion of surgical training. CONCLUSIONS: We describe the successful integration and sustainability of electronic surgical logbooks for trainees across Sub-Saharan Africa. However context-appropriate resources are essential for Low- and Middle-Income Countries. Internet connectivity may hinder the achievement of several Global Surgery objectives in Sub-Saharan Africa.

Visuospatial abilities and fine motor experiences influence acquisition and maintenance of fundamentals of laparoscopic surgery (FLS) task performance.

BACKGROUND: Minimally invasive surgery poses a unique learning curve due to the requirement for non-intuitive psychomotor skills. The fundamentals of laparoscopic surgery (FLS) program trains and certifies residents in such skills. However, innate predictors of FLS performance and maintenance remain to be described. This single-centre observational study aimed to assess for candidate factors influencing the acquisition and maintenance of FLS performance amongst a surgically naïve cohort. METHODS: Laparoscopically naïve medical students were recruited from pre-clinical university grades. Participants completed five visuospatial/psychomotor tests and a questionnaire surveying non-surgical experiences and personality traits. Individuals completed baseline assessments of FLS standard tasks followed by an intensive training course over week one and two on inanimate box trainers. A post-training assessment was performed in week three to evaluate acquisition. Participants were withdrawn from exposure and retested at four 1-month intervals to assess maintenance requirements. RESULTS: Forty-nine participants enrolled with 35 (71.4%) and 33 (67.3%) completing acquisition and maintenance phases, respectively. Mean age of participants was 19.3 (± 1.2) years with 68.6% female predominance. Participants demonstrated significant improvements in all five tasks during the acquisition (p < 0.05) period and maintenance of skills with task exposure at 1-month intervals. Significant predictors of skill acquisition included: card rotations for intracorporeal knot (p = 0.027) and combined tasks (p = 0.028) and cube comparisons for extracorporeal knot (p = 0.040). During skill maintenance: Card rotations predicted performance across all tasks (p < 0.05), Cube comparisons for tasks 1/2/4/5 (p < 0.05), PicSOR for peg transfer (p = 0.017) and grooved pegboard for peg transfer (p = 0.023) and ligating-loop (p = 0.038) tasks. Musical instrument experience demonstrated associations with skill acquisition in peg transfer (p = 0.042) and intracorporeal knot (p = 0.034) while video gaming predicted performance in these tasks (p < 0.05) during the maintenance phase. A sporting background or competitive personality did not influence skill performance. CONCLUSIONS: Multiple visuospatial abilities and non-surgical experiences positively influenced FLS performance during skill acquisition and/or maintenance. Further consideration to these individual factors may facilitate selection of more technically adaptable surgical residents.

Playing to your skills: a randomised controlled trial evaluating a dedicated video game for minimally invasive surgery.

BACKGROUND: Video gaming demands elements of visual attention, hand-eye coordination and depth perception which may be contiguous with laparoscopic skill development. General video gaming has demonstrated altered cortical plasticity and improved baseline/acquisition of minimally invasive skills. The present study aimed to evaluate for skill acquisition associated with a commercially available dedicated laparoscopic video game (Underground) and its unique (laparoscopic-like) controller for the Nintendo®Wii U™ console. METHODS: This single-blinded randomised controlled study was conducted with laparoscopically naive student volunteers of limited (< 3 h/week) video gaming backgrounds. Baseline laparoscopic skills were assessed using four basic tasks on the Virtual Reality (VR) simulator (LAP MentorTM, 3D systems, Colorado, USA). Twenty participants were randomised to two groups; Group A was requested to complete 5 h of video gaming (Underground) per week and Group B to avoid gaming beyond their normal frequency. After 4 weeks participants were reassessed using the same VR tasks. Changes in simulator performances were assessed for each group and for intergroup variances using mixed model regression. RESULTS: Significant inter- and intragroup performances were present for the video gaming and controls across four basic tasks. The video gaming group demonstrated significant improvements in thirty-one of the metrics examined including dominant (p ≤ 0.004) and non-dominant (p < 0.050) instrument movements, pathlengths (p ≤ 0.040), time taken (p ≤ 0.021) and end score [p ≤ 0.046, (task-dependent)]. The control group demonstrated improvements in fourteen measures. The video gaming group demonstrated significant (p < 0.05) improvements compared to the control in five metrics. Despite encouraged gameplay and the console in participants' domiciles, voluntary engagement was lower than directed due to factors including: game enjoyment (33.3%), lack of available time (22.2%) and entertainment distractions (11.1%). CONCLUSION: Our work revealed significant value in training using a dedicated laparoscopic video game for acquisition of virtual laparoscopic skills. This novel serious game may provide foundations for future surgical developments on game consoles in the home environment.

Port insertion for minimally invasive surgery: a report of practices in the Irish Republic.

BACKGROUND: With rapidly evolving surgical technologies, minimally invasive surgery (MIS) has become the mainstay approach for many surgeons worldwide. As laparoscopic surgery was introduced in Ireland over two decades ago, we may be encountering a higher prevalence of related complications. AIMS: This study aimed to gather data pertaining to risk factors for port-site herniation in MIS. METHODS: A 14-point anonymous questionnaire was distributed electronically between January and May 2017 to consultant and trainee laparoscopists in the Republic of Ireland. This survey related to laparoscopic volume and surgical approaches to laparoscopic port-sites. RESULTS: There were 172 eligible responses nationally. Approaches to peritoneal access included Hasson, veress (blind puncture) and SILS were 66.3, 32.6 and 1.2%, respectively. Senior surgeons and specialists in Obstetrics and Gynaecology (OBGYN) reported significantly higher utilisations of closed peritoneal access (p < 0.05). Of the participants, 119 (69.2%) reported using a bladeless trocar over a bladed type. Fascial closure was utilised in 94.2% of ≥ 10 mm and 2.3% of 5-mm ports using absorbable suture in 76.7%, non-absorbable suture in 14.5% and port closure devices in 8.7%. Perceptions of risk factors for PSH were not congruent with significant variations in responses between levels of expertise. CONCLUSIONS: This study demonstrates significant variations in laparoscopic port-site practices amongst surgeons nationally. The new era of practitioners may benefit from evidence-based technical workshops and guidelines to increase awareness and reduce potential complications.

The correlation between fundamental characteristics and first-time performance in laparoscopic tasks.

BACKGROUND: The ability of characteristics to predict first time performance in laparoscopic tasks is not well described. Videogame experience predicts positive performance in laparoscopic experiences but its mechanism and confounding-association with aptitude remains to be elucidated. This study sought to evaluate for innate predictors of laparoscopic performance in surgically naive individuals with minimal videogame exposure. METHODS: Participants with no prior laparoscopic exposure and minimal videogaming experience were recruited consecutively from preclinical years at a medical university. Participants completed four visuospatial, one psychomotor aptitude test and an electronic survey, followed by four laparoscopic tasks on a validated Virtual Reality simulator (LAP Mentor™). RESULTS: Twenty eligible individuals participated with a mean age of 20.8 (±3.8) years. Significant intra-aptitude performance correlations were present amongst 75% of the visuospatial tests. These visuospatial aptitudes correlated significantly with multiple laparoscopic task metrics: number of movements of a dominant instrument (rs ≥ -0.46), accuracy rate of clip placement (rs ≥ 0.50) and time taken (rs ≥ -0.47) (p < 0.05). Musical Instrument experience predicted higher average speed of instruments (rs ≥ 0.47) (p < 0.05). Participant's revised competitive index level predicted lower proficiency in laparoscopic metrics including: pathlength, economy and number of movements of dominant instrument (rs ≥ 0.46) (p < 0.05). CONCLUSION: Multiple visuospatial aptitudes and innate competitive level influenced baseline laparoscopic performances across several tasks in surgically naïve individuals.

Development and evaluation of a trauma decision-making simulator in Oculus virtual reality.

BACKGROUND: Consumer-available virtual-reality technology was launched in 2016 with strong foundations in the entertainment-industry. We developed an innovative medical-training simulator on the Oculus™ Gear-VR platform. This novel application was developed utilising internationally recognised Advanced Trauma Life Support (ATLS) principles, requiring decision-making skills for critically-injured virtual-patients. METHODS: Participants were recruited in June, 2016 at a single-centre trauma-course (ATLS, Leinster, Ireland) and trialled the platform. Simulator performances were correlated with individual expertise and course-performance measures. A post-intervention questionnaire relating to validity-aspects was completed. RESULTS: Eighteen(81.8%) eligible-candidates and eleven(84.6%) course-instructors voluntarily participated. The survey-responders mean-age was 38.9(±11.0) years with 80.8% male predominance. The instructor-group caused significantly less fatal-errors (p < 0.050) and proportions of incorrect-decisions (p < 0.050). The VR-hardware and trauma-application's mean ratings were 5.09 and 5.04 out of 7 respectively. Participants reported it was an enjoyable method of learning (median-6.0), the learning platform of choice (median-5.0) and a cost-effective training tool (median-5.0). CONCLUSION: Our research has demonstrated evidence of validity-criteria for a concept application on virtual-reality headsets. We believe that virtual-reality technology is a viable platform for medical-simulation into the future.

360° Operative Videos: A Randomised Cross-Over Study Evaluating Attentiveness and Information Retention.

OBJECTIVE: Although two-dimensional (2D) and three-dimensional videos have traditionally provided foundations for reviewing operative procedures, the recent 360º format may provide new dimensions to surgical education. This study sought to describe the production of a high quality 360º video for an index-operation (augmented with educational material), while evaluating for variances in attentiveness, information retention, and appraisal compared to 2D. DESIGN: A 6-camera synchronised array (GoPro Omni, [California, United States]) was suspended inverted and recorded an elective laparoscopic cholecystectomy in 2016. A single-blinded randomised cross-over study was performed to evaluate this video in 360º vs 2D formats. Group A experienced the 360º video using Samsung (Suwon, South-Korea) GearVR virtual-reality headsets, followed by the 2D experience on a 75-inch television. Group B were reversed. Each video was probed at designated time points for engagement levels and task-unrelated images or thoughts. Alternating question banks were administered following each video experience. Feedback was obtained via a short survey at study completion. SETTING: The New Academic and Education Building (NAEB) in Dublin, Royal College of Surgeons in Ireland, July 2017. PARTICIPANTS: Preclinical undergraduate students from a medical university in Ireland. RESULTS: Forty students participated with a mean age of 23.2 ± 4.5 years and equal sex involvement. The 360º video demonstrated significantly higher engagement (p < 0.01) throughout the experience and lower task-unrelated images or thoughts (p < 0.01). Significant variances in information retention between the 2 groups were absent (p = 0.143) but most (65%) reported the 360º video as their learning platform of choice. Mean appraisal levels for the 360º platform were positive with mean responses of >8/10 for the platform for learning, immersion, and entertainment. CONCLUSIONS: This study describes the successful development and evaluation of a 360º operative video. This new video format demonstrated significant engagement and attentiveness benefits compared to traditional 2D formats. This requires further evaluation in the field of technology enhanced learning.

Objective scoring of an electronic surgical logbook: Analysis of impact and observations within a surgical training body.

BACKGROUND: Historically, evaluating operative-volumes has proven difficult due to mass-variability in operative-complexities and participation. This study aimed to introduce a national scoring interface for residents' operative-logs while forming meaningful observations on specialities, training-institutes and technical competency. METHODS: A weighted-scoring algorithm was applied prospectively to residents' operative volumes since July 8th, 2013 with daily web-based quantitative feedback. Pre and post intervention analyses were performed with historical volumes. Operative volumes were correlated with work-based and university technical-skills' assessments. RESULTS: Ninety-five residents completed two-year preliminary training since 2013 recording 79,490 operations. These residents recorded significant (p < 0.050) increases in mean-score (case-load), total, performed and assisted operations of >16,528 (50%), 234 (45%), 115 (66%) and 113 (33%) respectively. The number of resident-performed operations was a significant predictor of performance in work-based and university technical-skills assessments (p < 0.050). There were no associations between these measures and the volume of assisted-operations. CONCLUSIONS: Open-benchmarking of surgical-volumes stimulates residents to actively pursue operative-opportunities and record those experiences. It provides objective performance data on residents and training-institutes while providing evidence that level of operative participation is significant in technical skills development.
