Operative learning curve trajectory in a cohort of surgical trainees

Assessing Neurosurgery Training: Accreditation Council for Graduate Medical Education Case Minimums Versus Surgical Autonomy

BACKGROUND AND OBJECTIVES

The Accreditation Council for Graduate Medical Education (ACGME) requires neurosurgery residents to reach a set number of cases in specified procedure types (case minimums) before graduation and mandates completion of Milestones. We used the Surgical Autonomy Program, a validated method of autonomy-based resident evaluation, to determine the number of cases it took for residents to become competent and compared these with the ACGME case minimums.

METHODS

We collected data from neurosurgery residents at Duke University on 7 procedures (tumor craniotomy, trauma craniotomy, ventriculoperitoneal shunt, anterior cervical discectomy and fusion (ACDF), posterior cervical fusion (PCF), discectomy/laminectomy, and posterior thoracolumbar spinal fusion [PSF]). We defined competency as being graded at the highest autonomy level in the Surgical Autonomy Program by attending neurosurgeons for the first and second time and determined the case volume on the ACGME case log when these were achieved. These results were analyzed with summary statistics.

RESULTS

The median case volume among residents (N = 4-8) for the first and second competency rating (and ACGME minimum) for each procedure type was found to be: tumor: 44.5 and 64.5 (min. 60), trauma: 21 and 30 (min. 60), ventriculoperitoneal shunt: 11.3 and 13 (min. 20), ACDF: 30 and 32.5 (min. 20), PCF: 24 and 40 (min. 30), discectomy/laminectomy: 28 and 36 (min. 30), and PSF: 51 and 54 (min. 30).

CONCLUSION

We found variation in the case numbers to reach competency and that for some procedures (tumor, ACDF, PCF, discectomy/laminectomy, and PSF), most residents required more cases than the ACGME case minimums to achieve competency. The ACGME case minimums may not accurately reflect the number of cases required for neurosurgical residents to reach competency. To promote trainee-centered education, individualized, competency-based evaluation systems may be better determining readiness for graduation, including a system that builds off the established ACGME Milestones.

The Perceived Impact of COVID-19 on Graduate Medical Education and Recommendations for Bridging the Educational Gap

INTRODUCTION

COVID-19 generated a system-wide shock causing an unbalanced equilibrium between producing adequately trained physicians and meeting extraordinary operational needs. Previous studies report the experience of surgical residents during COVID-19 at a regional level. This study measures the learning losses related with the redeployment of highly specialized medical professionals to the care of COVID-19 patients, while we systematically investigate proposed remedial strategies.

METHODS

We administered an online cross-sectional survey in 67 countries capturing training inputs (i.e., surgeries and seminars residents participated in) before and during the pandemic and retrieved residents' expected learning outputs, career prospects and recommended remedial measures for learning losses. We compared responses of residents working in (treatment group) and out (control group) of hospitals with COVID-19 patients.

RESULTS

The analysis included 432 plastic surgery residents who were in training during the pandemic. Most of the learning losses were found in COVID-19 hospitals with 37% and 16% loss of surgeries and seminars, respectively, per week. Moreover, 74%, 44%, and 55% of residents expected their surgical skill, scientific knowledge, and overall competence, respectively, to be lower than those of residents who graduated before COVID. Residents in COVID-19 hospitals reported participating in significantly (P < 0.001) fewer surgeries and having significantly (P < 0.001) lower surgical skill relative to those not in COVID-19 hospitals.

CONCLUSIONS

The perceived lower competence and the fall-off in surgical skill and scientific knowledge among future surgeons suggest that health-care systems globally may have limited capacity to perform specialized and costly procedures in the future.

Generating a Prioritized List of Operative Procedures for Simulation-based Assessment of General Surgery Trainees Through Consensus

OBJECTIVE

To develop appropriate content for high-stakes simulation-based assessments of operative competence in general surgery training through consensus.

BACKGROUND

Valid methods of summative operative competence assessment are required by competency-based training programs in surgery.

METHOD

An online Delphi consensus study was conducted. Procedures were derived from the competency expectations outlined by the Joint Committee on Surgical Training Curriculum 2021, and subsequent brainstorming. Procedures were rated according to their perceived importance, perceived procedural risk, how frequently they are performed, and simualtion feasibility by a purposive sample of 30 surgical trainers and a 5-person steering group. A modified Copenhagen Academy for Medical Education and Simulation Needs Assessment Formula was applied to the generated data to produce ranked procedural lists, which were returned to participants for re-prioritization.

RESULTS

Prioritized lists were generated for simulation-based operative competence assessments at 2 key stages of training; the end of 'phase 2' prior to the development of a sub-specialty interest, and the end of 'phase 3', that is, end-of-training certification. A total of 21 and 16 procedures were deemed suitable for assessments at each of these stages, respectively.

CONCLUSIONS

This study describes a national needs assessment approach to content generation for simulation-based assessments of operative competence in general surgery using Delphi consensus methodology. The prioritized procedural lists generated by this study can be used to further develop operative skill assessments for use in high-stakes scenarios, such as trainee progression, entrustment, and end-of-training certification, before subsequent validity testing.

Defining the Disparity: A Multi-Institutional Analysis of Factors Associated With Decreased Resident Operative Experience

INTRODUCTION

Technical learning in surgical training is multifaceted and existing literature suggests a positive relationship between case volume and proficiency. Little is known about factors associated with a decreased volume of operative experience. This study aimed to identify resident and program factors associated with general surgery residents (GSR) in the bottom quartile of logged case volume upon program completion.

METHODS

A post hoc analysis of a multicenter study was used to examine case logs for categorical GSR. Participants included graduates between 2010 and 2020 from 20 programs. Residents below and above the 25th percentile for total operative volume were compared.

RESULTS

The present study includes 1343 GSR who graduated over the 11-y period. In total, 336 residents were below the 25th percentile and 1007 residents were above the 25th percentile. Those below the 25th percentile were more likely to be female (41% versus 34%, P = 0.02), identify as underrepresented in medicine (22% versus 14%, P < 0.01), and pursue fellowship (86% versus 80%, P = 0.01) compared to those above the 25th percentile. Residents below the 25th percentile were more likely to have graduated from a low volume program (55% versus 25%, P < 0.01) and from top National Institutes of Health funded institutions (57% versus 52%, P = 0.01).

CONCLUSIONS

This study identified individual and program characteristics associated with lower operative volume of GSR. Understanding such characteristics will aid surgical educators to achieve better equity in training.

Separating the components of an abdominal wall fellowship

Complex abdominal wall reconstruction is an emerging subspecialty yet, despite the abundance of abdominal wall hernias requiring treatment and the increasing complexity of this type of surgery, there are few opportunities for surgeons to gain subspecialist training in this field. In this paper we discuss the need for focused training in complex abdominal wall reconstruction, outline some of the problems that may be hindering the availability of such opportunities and propose potential solutions to these issues.

Enhanced Recovery after Surgery Applied to Pediatric Laparoscopic Cholecystectomy for Simple Cholelithiasis: Feasibility and Teaching Insights

BACKGROUND

Same-day discharge after a cholecystectomy is a common practice in the adult population and has been demonstrated as safe and viable for children as well. However, there is a lack of comprehensive teaching models for pediatric cholecystectomy. Drawing inspiration from standardized outpatient procedures, this study aimed to assess the clinical outcomes and feasibility of teaching programs and an Enhanced Recovery After Surgery (ERAS) protocol following ambulatory laparoscopic cholecystectomy in pediatric patients.

METHODS

In 2015, an ERAS pathway for laparoscopic cholecystectomy (LC) was implemented, focusing on admission procedures, surgery timing, anesthetic choices, analgesia, postoperative feeding, mobilization, and pain assessment. Day-case surgery was not applicable for acute cholecystitis, choledochal lithiasis, sickle cell disease, and hereditary spherocytosis cases. The protocol was employed for a group of attending surgeons and fellows, as well as a group of residents under the supervision of experienced surgeons. A retrospective analysis was conducted to evaluate the feasibility and effectiveness of ambulatory cholecystectomy in children and its utilization in training pediatric surgical trainees.

RESULTS

Between 2015 and 2020, a total of 33 patients were included from a cohort of 162 children who underwent LC, with 15 children operated on by senior surgeons and 18 by young surgeons. The primary diagnoses were symptomatic gallbladder lithiasis (n = 32) and biliary dyskinesia (n = 1). The median age at the time of surgery was 11.3 years (interquartile range (IQR) 4.9-18), and the median duration of surgery was 54 min (IQR 13-145). One intraoperative complication occurred, involving gallbladder rupture and the dissemination of lithiasis into the peritoneal cavity. Three patients (9%) required an overnight stay, while no postoperative complications or readmissions within 30 days were observed. ERAS was successfully implemented in 30 patients (91%). No significant differences in surgical outcomes were noted between senior and young surgeons. At an average follow-up of 55 months, no long-term sequelae were identified.

CONCLUSIONS

These findings align with the current trend of increasing use of outpatient laparoscopic cholecystectomy and underscore its feasibility in the pediatric population. The application of a structured ERAS protocol appears viable and practical for training the next generation of pediatric surgeons.

Right Case, Right Time: Which Procedures Best Differentiate General Surgery Trainees' Operative Performance?

OBJECTIVE

Assessing surgical trainee operative performance is time- and resource-intensive. To maximize the utility of each assessment, it is important to understand which assessment activities provide the most information about a trainee's performance. The objective of this study is to identify the procedures that best differentiate performance for each general surgery postgraduate year (PGY)-level, leading to recommendations for targeted assessment.

DESIGN

The Society for Improving Medical Professional Learning (SIMPL) operative performance ratings were modeled using a multilevel Rasch model which identified the highest and lowest performing trainees for each PGY-level. For each procedure within each PGY-level, a procedural performance discrimination index was calculated by subtracting the proportion of "practice-ready" ratings of the lowest performing trainees from the proportion of "practice-ready" ratings of the highest performing trainees. Four-quadrant plots were created using the median procedure volume and median discrimination index for each PGY-level. All procedures within the upper right quadrant were considered "highly differentiating, high volume" procedures.

SETTING

This study was conducted across 70 general surgical residency programs who are members of the SIMPL collaborative.

PARTICIPANTS

A total of 54,790 operative performance evaluations of categorical general surgery trainees were collected between 2015 and 2021. Trainees who had at least 1 procedure in common were included. Procedures with less than 25 evaluations per training year were excluded.

RESULTS

The total number of evaluations per procedure ranged from 25 to 2,131. Discrimination values were generated for 51 (PGY1), 54 (PGY2), 92 (PGY3), 105 (PGY4), and 103 (PGY5) procedures. Using the above criteria, a total of 12 (PGY1), 15 (PGY2), 22 (PGY3), 21 (PGY4), and 28 (PGY5) procedures were identified as highly differentiating, high volume procedures.

CONCLUSIONS

Our study draws on national data to identify procedures which are most useful in differentiating trainee operative performance at each PGY-level. This list of procedures can be used to guide targeted assessment and improve assessment efficiency.

Learning curve of laparoscopic cholecystectomy: a risk-adjusted cumulative summation (RA-CUSUM) analysis of six general surgery residents

BACKGROUND

Laparoscopic cholecystectomy (LapC) is one of the most frequently performed surgical procedures worldwide. Reaching technical competency in performing LapC is considered one essential task for young surgeons. Investigating the learning curve for LapC (LC-LapC) may provide important information regarding the learning process and guide the training pathway of residents, improving educational outcomes. The present study aimed to investigate LC-LapC among general surgery residents (GSRs).

METHODS

Operative surgical reports of consecutive patients undergoing LapC performed by GSRs attending the General Surgery Residency Program at the University of Milan were analysed. Data on patient- and surgery-related variables were obtained from the ICD-9-CM diagnosis codes and gathered. A multidimensional assessment of the LC was performed through Cumulative Sum (CUSUM) and Risk-Adjusted (RA)-CUSUM analysis.

RESULTS

340 patients operated by 6 GSRs were collected. The CUSUM and RA-CUSUM graphs based on surgical failures allowed to distinguish two defined phases for all GSRs: an initial phase ending at the peak, so-called learning phase, followed by a phase in which there was a significant decrease in failure incidence, so-called proficiency phase. The learning phase was completed for all GSRs at most within 25 procedures, but the trend of the curves and the number of procedures needed to achieve technical competency varied among operators ranging between 7 and 25.

CONCLUSIONS

The present study suggested that at most 25 procedures might be sufficient to acquire technical competency in LapC. The variability in the number of procedures needed to complete the LC, ranging between 7 and 25, could be due to the heterogeneous scenarios in which LapC was performed, and deserves to be investigated through a prospective study involving a larger number of GSRs and institutions.

Characterizing individual trainee learning curves in surgical training: Challenges and opportunities

The surgical learning curve is an observable and measurable phenomenon. In the era of competency-based approaches to surgical training, monitoring the trajectory of individual trainee competence attainment could represent a meaningful method of formative and summative assessment. While technology can assist this approach, a number of significant barriers to the implementation of such assessment methods remain, including: accurate data collection, standard setting, and reliable assessment. Translating individual learning curve data into quantifiable case minimum targets in training poses further difficulties, and may not be possible for all procedures, particularly those that are less frequently performed and assessed. In spite of these challenges, significant benefits could be realized through an individualized approach to competency assessment using trainee learning curve data. Tracking competence acquisition against criterion-referenced standards could allow for targeted training and remediation, conforming with modern theories of adult education and empowering trainees to take control of their own learning. Learning curve data could also be used to assess the effects of educational interventions such as simulation-based training on subsequent competence acquisition rates. Ultimately, the individual learning curves of trainees could be used to inform personalised decisions regarding entrustment, credentialing, and certification, allowing training programmes to move beyond minimum operative experience targets as a crude proxy measure of competence.

Learning curve in open groin hernia surgery: nationwide register-based study

BACKGROUND

Current recommendations regarding the number of open groin hernia repairs that surgical trainees are required to perform during their residency are arbitrarily defined and vary between different curricula. This register-based study sought to investigate the learning curve of surgeons performing open anterior mesh repair for groin hernia by assessing hernia recurrence rates, surgical complications and operating times in relation to the number of procedures performed.

METHOD

Nationwide data on open anterior mesh repair for groin hernia performed by surgical residents were collected from the Swedish Hernia Register between 2005 and 2020. The data were analysed in a cohort undergoing procedures carried out by surgeons performing their first registered repair as resident general surgeons. Repairs by surgeons with fewer than 30 repairs were excluded.

RESULTS

A total of 38 845 repairs carried out by 663 surgeons were included. Operation time decreased with increasing number of performed procedures, mean (s.d.) operation time was 79 (26) min for the first 15 procedures and 60 (23) min after 241 procedures (P <0.001). A turning point where complication rates began to decrease was seen after 60 procedures. Complication rates were 3.6 per cent (396 of 10 978) for procedures 31-60 and 2.7 per cent (157 of 5 798) for procedures 61-120 (P = 0.002). There was no significant relationship between the number of procedures performed and the rate of operation on for recurrence (P = 0.894).

CONCLUSION

Sixty performed procedures during surgical residency is a reasonable target for achieving competency to perform open anterior mesh repair for groin hernia safely without supervision.

Early Evaluation of a New French Surgery Course in the Best Practice of Dealing With Major Incidents and Mass Casualty Events

OBJECTIVE

The main objective of this study is to evaluate the impact of a nationwide 5-month course aimed to prepare surgeons for Major Incidents through the acquisition of key knowledge and competencies. Learners' satisfaction was also measured as a secondary objective.

DESIGN

This course was evaluated thanks to various teaching efficacy metrics, mainly based on Kirkpatrick's hierarchy in medical education. Gain in knowledge of participants was evaluated by multiple-choice tests. Self-reported confidence was measured with 2 detailed pre and post training questionnaires.

SETTING

Creation in 2020 of a nationwide, optional and comprehensive Surgical Training in War and Disaster Situation as part of the French surgery residency program. In 2021, data was gathered regarding the impact of the course on participants' knowledge and competencies.

PARTICIPANTS

The study included 26 students in the 2021 cohort (13 residents and 13 practitioners).

RESULTS

Mean scores were significantly higher in the post-test compared to the pre-test, showing significant increase in participants' knowledge during the course: 73,3% vs. 47,3% respectively (p ≤ 0.001). Average learners' confidence scores to perform technical procedures showed at least a +1-point increase on the Likert scale for 65% of items tested (p ≤ 0.001). 89% of items showed at least a +1-point increase on the Likert scale when it came to average learners' confidence score on dealing with complicated situations (p ≤ 0.001). Our post-training satisfaction survey showed that 92% of all participants have noticed the impact of the course on their daily practice.

CONCLUSION

Our study shows that the third level of Kirkpatrick's hierarchy in medical education was reached. This course therefore appears to be meeting the objectives set by the Ministry of Health. Being only 2 years old, it is on the road to gathering momentum and further development.

Inguinal hernia surgery learning curves by associate clinicians

BACKGROUND

Open inguinal hernia repair is the most commonly performed procedure in general surgery in sub-Saharan Africa, but data on its learning curve are lacking. This study evaluated the learning curve characteristics to improve surgical training and enable scaling up hernia surgery in low- and middle-income countries.

METHODS

Logbook data of associate clinicians enrolled in a surgical training program in Sierra Leone were collected and their first 55 hernia surgeries following the Bassini technique (herniorrhaphies) were analyzed in cohorts of five cases. Studied variables were gradient of decline of operating time, variation in operating time, and length of stay (LOS). Eleven subsequent cohorts of each five herniorrhaphies were investigated.

RESULTS

Seventy-five trainees enrolled in the training program between 2011 and 2020 were eligible for inclusion. Thirty-one (41.3%) performed the minimum of 55 herniorrhaphies, and had also complete personal logbook data. Mean operating times dropped from 79.6 (95% CI 75.3-84.0) to 48.6 (95% CI 44.3-52.9) minutes between the first and last cohort, while standard deviation in operating time nearly halved to 15.4 (95% CI 11.7-20.0) minutes, and LOS was shortened by 3 days (8.5 days, 95%CI 6.1-10.8 vs. 5.4 days, 95% 3.1-7.6). Operating times flattened after 31-35 cases which corresponded with 1.5 years of training.

CONCLUSIONS

The learning curve of inguinal hernia surgery for associate clinicians flattens after 31-35 procedures. Training programs can be tailored based on this finding. The recorded learning curve may serve as a baseline for future training techniques.

Training curriculum in minimally invasive emergency digestive surgery: 2022 WSES position paper

BACKGROUND

Minimally invasive surgery (MIS), including laparoscopic and robotic approaches, is widely adopted in elective digestive surgery, but selectively used for surgical emergencies. The present position paper summarizes the available evidence concerning the learning curve to achieve proficiency in emergency MIS and provides five expert opinion statements, which may form the basis for developing standardized curricula and training programs in emergency MIS.

METHODS

This position paper was conducted according to the World Society of Emergency Surgery methodology. A steering committee and an international expert panel were involved in the critical appraisal of the literature and the development of the consensus statements.

RESULTS

Thirteen studies regarding the learning curve in emergency MIS were selected. All but one study considered laparoscopic appendectomy. Only one study reported on emergency robotic surgery. In most of the studies, proficiency was achieved after an average of 30 procedures (range: 20-107) depending on the initial surgeon's experience. High heterogeneity was noted in the way the learning curve was assessed. The experts claim that further studies investigating learning curve processes in emergency MIS are needed. The emergency surgeon curriculum should include a progressive and adequate training based on simulation, supervised clinical practice (proctoring), and surgical fellowships. The results should be evaluated by adopting a credentialing system to ensure quality standards. Surgical proficiency should be maintained with a minimum caseload and constantly evaluated. Moreover, the training process should involve the entire surgical team to facilitate the surgeon's proficiency.

CONCLUSIONS

Limited evidence exists concerning the learning process in laparoscopic and robotic emergency surgery. The proposed statements should be seen as a preliminary guide for the surgical community while stressing the need for further research.

Defining operative experience targets in surgical training: A systematic review

BACKGROUND

The surgical learning curve is an observable and measurable phenomenon. Operative experience targets are well established as a proxy measure for operative competence in surgical training across jurisdictions. The aim of this study was to critique the available evidence regarding the relationship between operative experience in surgical training and trainee competence.

METHODS

A systematic review of the PubMed, Embase, Web of Science, and Cochrane library databases was conducted in accordance with the Preferred Items for Systematic Reviews and Meta-Analyses guidelines. Articles were sought that defined the relationship between procedural volume in surgical training and trainee competence, proficiency, or mastery. The educational impact of included studies was evaluated using a modified Kirkpatrick model.

RESULTS

Of 3,672 records identified on database searching, 30 papers were ultimately included. Fourteen studies defined operative experience thresholds using operative time as a surrogate measure of competence, whereas another 8 used trainer assessments of operative performance (Kirkpatrick level 3). A further 5 studies were able to determine the relationship between trainee case volumes and subsequent patient outcomes (Kirkpatrick level 4b).

CONCLUSION

Many studies have recorded competent trainee performance in key index procedures after reaching experience threshold numbers in excess of currently mandated targets across jurisdictions. The evidence relating current operative experience targets to patient outcomes across a range of surgical subspecialties of surgical subspecialties is lacking. This review supports a move toward criterion-based referencing of operative performance targets in surgical training.

Hospital compound-level endoscopy training quality performance: scoping the spectrum

Background and study aims  This study aimed to assess the quality of endoscopy training in a UK Statutory Educational Body compared with Joint Advisory Group on Gastrointestinal Endoscopy Training standards (JETS). Methods  A total of 28,298 training procedures recorded by 211 consecutive cross-specialty trainee endoscopists registered with JETS in 18 hospitals during 2019 were analyzed. Data included trainer and trainee numbers, training list frequency, procedures, direct observation of procedural skills (DOPS) completion, and key performance indicators. Results  Annual median training procedures per hospital were 1395 (interquartile range (IQR) 465-2365). Median trainers and trainees per unit were 11 (6-18) and 12 (7-16), respectively, (ratio 0.8 [0.7-1.3]). Annual training list frequency per trainee was 13 (10-17), 35.0 % short of Joint Advisory Group (JAG) standard (n = 20, P = 0.001, effect size -0.56). Median points per adjusted training list were 11 (5-18). Median DOPS per trainee and trainer were three (1-6) and four (1-7) respectively; completing 0.2 DOPS (0.1-0.4) per list and amounting to six (2-12) per 200 procedures: fewer than half of the JAG standard (20 per 200) (P < 0.001, -0.61). Esophagogastroduodenoscopy median KPI: J maneuver 94 % (90-96), D2 intubation 93 % (91-96); Colonoscopy KPI: cecal intubation 82 % (72-90), polyp detection rate 25 % (18-34). Compound hospital score ranged from nine to 26 (median 17 [14-20]). Conclusions  Important performance disparity emerged with three-fold variation in compound hospital training quality and most units underperforming compared with JAG standards. Trainees and training program directors should be aware of such metrics to improve quality endoscopy educational programs and consider formal adjuncts to optimize training.

Assessing Operative Skill in the Competency-based Education Era: Lessons From the UK and Ireland

INTRODUCTION

Decisions regarding the operative competence of surgical residents in the United Kingdom and Ireland are informed by operative workplace-based assessments (WBAs) and operative number targets for index procedures. This review seeks to outline the validity evidence of these assessment methods.

METHODS

A review of the MEDLINE (Pubmed), EMBASE and Cochrane Library databases was undertaken in accordance with the Joanna Briggs Institute Protocol for Scoping Reviews (2020). Articles were included if they provided evidence of the validity of procedure-based assessments, direct observation of procedural skills, or indicative operative number targets. The educational impact of each article was evaluated using a modified Kirkpatrick model.

RESULTS

Twenty-eight articles outlining validity evidence of WBAs and operative number targets were synthesised by narrative review. Five studies documented users' views on current assessment methods (Kirkpatrick level 1). Two articles recorded changes in attitudes towards current operative assessments (level 2a). Ten studies documented the ability of current assessments to record improvements in operative competence (level 2b). Ten studies measured a change in behaviour as a result of the introduction of these assessments (level 3). One article studied the ability of operative assessments to predict clinical outcomes (level 4b).

CONCLUSIONS

Operative WBAs are reliable. Scores achieved correlate with both time spent in training and recorded operative experience. Trainers and residents have concerns regarding the subjectivity of these assessments and the opportunistic nature in which they are used. Operative number targets are not criterion-referenced, lack validity evidence, and may be set too low to ensure operative competence.

Training to proficiency in surgery using simulation: is there a moral obligation?

A deontological approach to surgical ethics advocates that patients have the right to receive the best care that can be provided. The 'learning curve' in surgical skill is an observable and measurable phenomenon. Surgical training may therefore carry risk to patients. This can occur directly, through inadvertent harm, or indirectly through theatre inefficiency and associated costs. Trainee surgeon operating, however, is necessary from a utilitarian perspective, with potential risk balanced by the greater societal need to train future independent surgeons.New technology means that the surgical learning curve could take place, at least in part, outside of the operating theatre. Simulation-based deliberate practice could be used to obtain a predetermined level of proficiency in a safe environment, followed by simulation-based assessment of operative competence. Such an approach would require an overhaul of the current training paradigm and significant investment in simulator technology. This may increasingly be viewed as necessary in light of well-discussed pressures on surgical trainees and trainers.This article discusses the obligations to trainees, trainers and training bodies raised by simulation technology, and outlines the current arguments both against and in favour of a simulation-based training-to-proficiency model in surgery. The significant changes to the current training paradigm that would be required to implement such a model are also discussed.

Reduction in ionizing radiation exposure during minimally invasive anterior plate osteosynthesis of distal radius fracture: Naive versus deliberate practice

This study aimed to decrease surgeon exposure to ionizing radiation through a new learning technique, "deliberate practice", which consists in improving performance by setting goals with feedback. The hypothesis was that exposure to ionizing radiation during distal radius fracture surgery using the minimally invasive plate osteosynthesis (MIPO) technique decreased faster with "deliberate" practice than with "naïve" practice. Radiographic dosimetry was measured in the first 30 fractures operated on by MIPO by 6 surgeons. The first 3 surgeons operated "naively" (Group 1) and the next 3 according to the "deliberate" procedure (Group 2). Group 2 received weekly feedback (number of exposed hands, number of fluoroscopic views, exposure duration, and X-ray dose). An expert, using fluoroscopic images and surgical videos, provided suggestions for improvement. Mean number of exposed hands was 23.66 in Group 1 and 1.9 in Group 2. Mean number of fluoroscopic views was 78.31 and 35.0, respectively. Mean X-ray exposure time was 74.34 and 32.89 s, respectively. Mean dosimetry was 1.40 mGy (and 0.59 mGy, respectively. The hypothesis was thus confirmed: dosimetry decreased faster in Group 2 than in Group 1. Teaching this deliberate practice should be generalized, to decrease the growth phase and increase the plateau phase of the learning curve.

What it takes to become an orthopaedic surgeon: A comparison of orthopaedic surgical training programmes in 10 countries focusing on structure and fellowship requirements

BACKGROUND

The quality of surgical training has been highlighted as one of the most important patient safety issues in the future. Training surgeons and supporting them to do their best should be considered integral in providing optimum and safe care for the individual patient and the best possible return on investment in training medical professionals. In 2011, an international consensus statement defined fundamental principles for surgical training.

PURPOSE

This study examines orthopaedic surgical training to explore the similarities and differences in the requirements for trainees to obtain board certification in ten countries.

METHODS

Countries of the Commonwealth Health Care Comparison: Canada, the United Kingdom, the United States of America, Australia, New Zealand, Germany, France, the Netherlands, Norway and Switzerland were chosen to be compared. The relevant information was extracted from official information from authorities and administrative bodies.

RESULTS

The study revealed significant differences in duration, organisation and assessment of training. So-called "competency-based" training is not featured in every country, and the manner of its implementation is variable. In particular, the numbers in surgical cases required to be accredited varies by country ranging from 1260 (UK) to 340 (Norway).

CONCLUSION

Despite the recommendation in 2011 for some degree of uniformity across surgical training in industrialised countries, evidence suggests wide variation in the training programmes which is likely to be a concern in both quality of training as well as present and future patient safety.

Australian general surgical trainee experience with inguinal hernia surgery: a review of international training programmes and the learning curve

BACKGROUND

There are no publications addressing the level of experience Australian surgical trainees achieve in inguinal hernia surgery. Internationally, some training boards have set minimum competency requirements, but this is not true in Australia. The longer learning curve for laparoscopic inguinal hernia repairs (LIHRs) compared to open inguinal hernia repairs (OIHRs) has placed greater demands on trainees.

METHODS

Logbook data on OIHR and LIHR for Australian surgical trainees who graduated as fellows between 2013 and 2018 were obtained. A literature review was performed to analyse international published logbook numbers for surgical trainees from the past decade. International training board requirements, estimations of the learning curve and hernia society guidelines for each procedure were reviewed.

RESULTS

In total, 7946 operations were recorded from 58 trainees. On average 49.2 OIHRs (range 13-101), 21.5 LIHRs (range 1-94) and 71.1 inguinal hernia repairs overall (range 25-129) were performed during training. The European Hernia Society recommends that at least 30-50 of each procedure be performed during training. The learning curves for LIHRs (50-100 procedures) have been shown to be longer than for OIHRs (40-64 procedures).

CONCLUSION

Australian general surgical trainees are achieving adequate primary operator logbook numbers for OIHRs but are not completing the required number of LIHRs. The tailored approach to inguinal hernia repair requires skill in both open and laparoscopic repairs. This may not be possible with the current training structure in Australia.

Surgical curriculum concordance: requiem for the educational dream

This study aimed to analyse the degree of relative variation in speciality-specific competencies required for Certification of Completion of Training (CCT) set by the UK Joint Committee for Surgical Training (JCST) 2021 curriculum. Regulatory body guidance related to operative and non-operative surgical skill competencies required for CCT were analysed and compared. Wide inter-speciality variation was demonstrated in the minimum number of logbook cases (median 815; range 54 to 2100), indexed operations (8; 5 to 24) and procedure-based assessments (35; 6 to 110). Academic competencies related to peer-reviewed publications, communications to learned societies and audits were aligned at zero, zero and three across specialities, respectively. Mandatory courses have been standardised with Advanced Trauma Life Support being the sole pre-requisite CCT for all. JCST certification guidelines have broadly standardised competency domains, yet large discrepancies persist regarding operative indicative numbers and assessments. This article serves as a definitive CCT guide regarding prevailing changes.

Does Structured Postgraduate Training Affect the Learning Curve in Direct Anterior Total Hip Arthroplasty? A Single Surgeon's First 200 Cases

Background

The direct anterior approach (DAA) used for primary total hip arthroplasty has been shown to improve early postoperative outcomes, but prior studies have identified a marked learning curve for surgeons transitioning to this approach. However, these studies do not capture surgeons with postgraduate fellowship training in DAA. Therefore, the purpose of this study was to evaluate the learning curve by comparing perioperative outcomes for the first 100 to latter 100 cases and first 50 to final 50 cases.

Methods

The first 200 consecutive primary total hip arthroplasties performed by a single surgeon were prospectively followed up for up to 2 years postoperatively. Data on demographic and perioperative factors, 90-day readmissions, and short- and long-term complications were collected. Radiographic outcomes included acetabular cup anteversion and abduction measurements. Logistic regressions were used to calculate odds ratios and confidence intervals for surgical time greater than 2 hours.

Results

The first 100 and second 100 cases had significant differences in operative times (118.1 vs 110.4 minutes, P = .009), acetabular abduction (38.3 vs 35.5 degrees, P = .001) and anteversion (13.5 vs 15.1 degrees, P = .009), and incidence of neuropraxia (41 vs 9%, P < .001). Estimated blood loss, transfusions, discharge disposition, length of stay, readmission, and other complications had no statistical significance between the first and second 100 cases. The first 50 cases had higher odds of surgical time greater than 2 hours (odds ratio = 5.2, 95% confidence interval = 1.84-14.75, P = .002) than the final 50 cases.

Conclusions

When compared with the existing literature, incorporation of DAA into fellowship training can lead to reduction in fractures and reoperation rates.

Laparoscopic appendectomy as an index procedure for surgical trainees: clinical outcomes and learning curve

Surgical training is essential to maintain safety standards in healthcare. The aim of this study is to evaluate learning curves and short-term postoperative outcomes of laparoscopic appendectomy (LA) performed by trainees (TRN) and attendings (ATT). The present study included the medical records of patients with acute appendicitis who underwent a fully LA in our department between January 2013 and December 2018. Cases were divided into trainees (TRN and ATT groups based on the experience of the operating surgeon. The primary outcome measures were 30-day morbidity and mortality. Preoperative patients' clinical characteristics, intraoperative findings, operative times, and postoperative hospitalization were compared. Operative times were used to extrapolate learning curves and evaluate the effects of changes in faculty using CUSUM charts. A propensity score matching analysis was performed to reduce differences between cohorts regarding both preoperative characteristics and intraoperative findings. A total of 1173 patients undergoing LA for acute appendicitis were included, of whom 521 (45%) in the TRN group and 652 (55%) in the ATT group. No significant differences were found between the two groups in terms of complication rates, operative times and length of hospital stay. However, CUSUM chart analysis showed decreased operating times in the TRN group. Operative times improved more quickly for advanced cases. The results of this study indicate that LA can be performed by trainees without detrimental effects on clinical outcomes, procedural safety, and operative times. However, the learning curve is longer than previously acknowledged.

Trainee Autonomy in Minimally Invasive General Surgery in the United States: Establishing a National Benchmark

OBJECTIVE

Minimally invasive surgery (MIS) is an integral component of General Surgery training and practice. Yet, little is known about how much autonomy General Surgery residents achieve in MIS procedures, and whether that amount is sufficient. This study aims to establish a contemporary benchmark for trainee autonomy in MIS procedures. We hypothesize that trainees achieve progressive autonomy, but fail to achieve meaningful autonomy in a substantial percentage of MIS procedures prior to graduation.

SETTING/PARTICIPANTS

Fifty General Surgery residency programs in the United States, from September 1, 2015 to March 19, 2020. All Categorical General Surgery Residents and Attending Surgeons within these programs were eligible.

DESIGN

Data were collected prospectively from attending surgeons and categorical General Surgery residents. Trainee autonomy was assessed using the 4-level Zwisch scale (Show and Tell, Active Help, Passive Help, and Supervision Only) on a smartphone application (SIMPL). MIS procedures included all laparoscopic, thoracoscopic, endoscopic, and endovascular/percutaneous procedures performed by residents during the study. Primary outcomes of interest were "meaningful autonomy" rates (i.e., scores in the top 2 categories of the Zwisch scale) by postgraduate year (PGY), and "progressive autonomy" (i.e., differences in autonomy between PGYs) in MIS procedures, as rated by attending surgeons. Primary outcomes were determined with descriptive statistics, one-way analysis of variance (ANOVA) and Z-tests. Secondary analyses compared (i) progressive autonomy between common MIS procedures, and (ii) progressive autonomy in MIS vs. non-MIS procedures.

RESULTS

A total of 106,054 evaluations were performed across 50 General Surgery residency programs, of which 38,985 (37%) were for MIS procedures. Attendings performed 44,842 (42%) of all evaluations, including 16,840 (43%) of MIS evaluations, while residents performed the rest. Overall, meaningful autonomy in MIS procedures increased from 14.1% (PGY1s) to 75.9% (PGY5s), with significant (p < 0.001) increases between each PGY level. Meaningful autonomy rates were higher in the MIS vs. non-MIS group [57.2% vs. 48.0%, p < 0.001], and progressed more rapidly in MIS vs. non-MIS, (p < 0.05). The 7 most common MIS procedures accounted for 83.5% (n = 14,058) of all MIS evaluations. Among PGY5s performing these procedures, meaningful autonomy rates (%) were: laparoscopic appendectomy (95%); laparoscopic cholecystectomy (93%); diagnostic laparoscopy (87%); upper/lower endoscopy (85%); laparoscopic hernia repair (72%); laparoscopic partial colectomy (58%); and laparoscopic sleeve gastrectomy (45%).

CONCLUSIONS

US General Surgery residents receive progressive autonomy in MIS procedures, and appear to progress more rapidly in MIS versus non-MIS procedures. However, residents fail to achieve meaningful autonomy in nearly 25% of MIS cases in their final year of residency, with higher rates of meaningful autonomy only achieved in a small subset of basic MIS procedures.

Does the Surgeon's Caseload Affect the Outcome in Laparoscopic Cholecystectomy for Acute Cholecystitis?

BACKGROUND

This study investigated how annual caseloads and the surgeon's previous experience influence the outcome in laparoscopic cholecystectomy (LCC) for acute cholecystitis.

METHODS

A total of 892 patients treated in Helsinki University Hospital in 2013-2016 were retrospectively analyzed. Surgeons were compared regarding volume-over 5 LCCs for acute cholecystitis a year versus 5 or fewer LCCs a year, and experience-attendings versus residents.

RESULTS

High-volume surgeons (n=14) operated faster than low-volume surgeons (n=62) (91 vs. 108 min, P<0.001). Examining only procedures with an attending present, high-volume attendings (n=7) converted less (14.9% vs. 32.0%, P<0.001) and operated faster (95 vs. 110 min, P<0.001) compared with low-volume attendings (n=41). The results of residents did not significantly differ from the results of attendings.

CONCLUSIONS

Attending surgeons, performing >5 LCCs for acute cholecystitis a year, have shorter operative times and lower conversion rates.

Resuscitation Opportunities for Fellows of Very Low Birth Weight Infants in the Vermont Oxford Network

BACKGROUND

Neonatal-perinatal medicine (NPM) fellowship programs must provide adequate delivery room (DR) experience to ensure that physicians can independently provide neonatal resuscitation to very low birth weight (VLBW) infants. The availability of learning opportunities is unknown.

METHODS

The number of VLBW (≤1500 g) and extremely low birth weight (ELBW) (<1000 g) deliveries, uses of continuous positive airway pressure, intubation, chest compressions, and epinephrine over 3 years at accredited civilian NPM fellowship program delivery hospitals were determined from the Vermont Oxford Network from 2012 to 2017. Using Poisson distributions, we estimated the expected probabilities of fellows experiencing a given number of cases over 3 years at each program.

RESULTS

Of the 94 NPM fellowships, 86 programs with 115 delivery hospitals and 62 699 VLBW deliveries (28 703 ELBW) were included. During a 3-year fellowship, the mean number of deliveries per fellow ranged from 14 to 214 (median: 60) for VLBWs and 7 to 107 (median: 27) for ELBWs. One-half of fellows were expected to see ≤23 ELBW deliveries and 52 VLBW deliveries, 24 instances of continuous positive airway pressure, 23 intubations, 2 instances of chest compressions, and 1 treatment with epinephrine.

CONCLUSIONS

The number of opportunities available to fellows for managing VLBW and ELBW infants in the DR is highly variable among programs. Fellows' exposure to key, high-risk DR procedures such as cardiopulmonary resuscitation is low at all programs. Fellowship programs should track fellow exposure to neonatal resuscitations in the DR and integrate supplemental learning opportunities. Given the low numbers, the number of new and existing NPM programs should be considered.

Task-Shifting and Task-Sharing in Neurosurgery: An International Survey of Current Practices in Low- and Middle-Income Countries

BACKGROUND

Because nearly 23,000 more neurosurgeons are needed globally to address 5 million essential neurosurgical cases that go untreated each year, there is an increasing interest in task-shifting and task-sharing (TS/S), delegating neurosurgical tasks to nonspecialists, particularly in low- and middle-income countries (LMICs). This global survey aimed to provide a cross-sectional understanding of the prevalence and structure of current neurosurgical TS/S practices in LMICs.

METHODS

The survey was distributed to a convenience sample of individuals providing neurosurgical care in LMICs with a Web-based survey link via electronic mailing lists of continental societies and various neurosurgical groups, conference announcements, e-mailing lists, and social media platforms. Country-level data were analyzed by descriptive statistics.

RESULTS

The survey yielded 127 responses from 47 LMICs; 20 countries (42.6%) reported ongoing TS/S. Most TS/S procedures involved emergency interventions, the top 3 being burr holes, craniotomy for hematoma evacuation, and external ventricular drain. Most (65.0%) believed that their Ministry of Health does not endorse TS/S (24.0% unsure), and only 11% believed that TS/S training was structured. There were few opportunities for TS/S providers to continue medical education (11.6%) or maintenance of certification (9.4%, or receive remuneration (4.2%).

CONCLUSIONS

TS/S is ongoing in many LMICs without substantial structure or oversight, which is concerning for patient safety. These data invite future clinical outcomes studies to assess effectiveness and discussions on policy recommendations such as standardized curricula, certification protocols, specialist oversight, and referral networks to increase the level of TS/S care and to continue to increase the specialist workforce.

The CURE Protocol: evaluation and external validation of a new public health strategy for treating paediatric hydrocephalus in low-resource settings

Introduction

Managing paediatric hydrocephalus with shunt placement is especially risky in resource-limited settings due to risks of infection and delayed life-threatening shunt obstruction. This study evaluated a new evidence-based treatment algorithm to reduce shunt-dependence in this context.

Methods

A prospective cohort design was used. The CURE Protocol employs preoperative and intraoperative data to choose between endoscopic treatment and shunt placement. Data were prospectively collected for 730 children in Uganda (managed by local neurosurgeons highly experienced in the protocol) and, for external validation, 96 children in Nigeria (managed by a local neurosurgeon trained in the protocol).

Results

The age distribution was similar between Uganda and Nigeria, but there were more cases of postinfectious hydrocephalus in Uganda (64.2% vs 26.0%, p<0.001). Initial treatment of hydrocephalus was similar at both centres and included either a shunt at first operation or endoscopic management without a shunt. The Nigerian cohort had a higher failure rate for endoscopic cases (adjusted HR 2.5 (95% CI 1.6 to 4.0), p<0.001), but not for shunt cases (adjusted HR 1.3 (0.5 to 3.0), p=0.6). Despite the difference in endoscopic failure rates, a similar proportion of the entire cohort was successfully treated without need for shunt at 6 months (55.2% in Nigeria vs 53.4% in Uganda, p=0.74).

Conclusion

Use of the CURE Protocol in two centres with different populations and surgeon experience yielded similar 6-month results, with over half of all children remaining shunt-free. Where feasible, this could represent a better public health strategy in low-resource settings than primary shunt placement.

Thoracic ultrasound competence for ultrasound-guided pleural procedures

Focused thoracic ultrasound has become essential in the guidance and direction of pleural interventions to reduce unwanted complications and as a result now forms a crucial component of physician training. Current training standards along with assessment methods vary widely, and are often not robust enough to ensure adequate competence.This review assesses the current state of training and assessment of thoracic ultrasound competence in various settings, allowing comparison with alternative competency based programmes. Future directions for training and assessment of thoracic ultrasound competence are discussed.

Training of Residents in Cardiac Surgery-Does It Have Impact on the Outcome?

OBJECTIVES

In many centers, training in cardiac surgery is considered to increase perioperative risk. This study aims to test whether a resident working as the main operator is a genuine risk factor.

METHODS

We analyzed patients who underwent elective isolated aortic valve replacement, elective isolated coronary artery bypass grafting, or both, in our institution, from 2008 to 2016. Redo- and off-pump surgery, ejection fraction < 30%, and other concomitant procedures were the exclusion criteria. After this selection, we included 3,077 patients in our study. Within this group, 357 (11.6%) had been operated by residents and 2,720 (88.4%) by senior surgeons. We performed propensity score matching using the nearest neighbor method with a ratio of 1:2, considering the most important preoperative conditions. In this way, the 357 patients operated by residents were matched with the 714 patients who were operated by senior surgeons. The standardized mean differences were highly reduced after matching, so both groups had similar risk profiles. We compared surgical data, postoperative adverse events, and the 30-day mortality between the two groups.

RESULTS

The times of surgery, cardiopulmonary bypass, and cross-clamp were longer if residents operated (p < 0.001). There were no differences regarding postoperative adverse events, time of mechanical ventilation, and the intensive care unit length of stay. The 30-day mortality rates of the two groups were very similar (p = 0.75, power = 0.8).

CONCLUSION

Training in cardiac surgery is safe, and carefully selected patients can be operated by residents without increased risk of perioperative mortality and complications.

Testicular torsion treatment: the horns of a dilemma?

INTRODUCTION

Testicular torsion treatment rests on the horns of a dilemma, with widespread national variation in whether the responsible surgical specialty is general surgery or urology, even in hospitals with both general surgery and urology emergency service assets. This study aimed to quantify higher surgical trainee operative experience and confidence in managing suspected testicular torsion in a single UK deanery (Wales).

MATERIALS AND METHODS

Anonymised logbook data were obtained via the Intercollegiate Surgical Curriculum Programme version 10 using the head of school report function for all general surgery (n=53) and urology (n=15) higher surgical trainees, which were combined with the distribution of an electronic self-administered questionnaire.

RESULTS

Median operative scrotal explorations recorded for all general surgery higher surgical trainees and senior general surgery higher surgical trainees (ST7+) was 7 (range 1-22) and 10 (range 1-22), compared with 21 (range 9-64, p=0.00104) and 24 (19-64, p<0.001) for urology higher surgical trainees. The questionnaire response rate was 64.6% (general surgery 31/50, urology 11/15). Confidence levels in assessing adult and paediatric patients were lower in general surgery when compared with urology higher surgical trainees: median adult confidence rate 7/10 compared with 9/10, and paediatric confidence rate 7/10 compared with 8/10 (p<0.001 and p=0.053, respectively). All higher surgical trainees preferred urology as the accountable hospital specialty when both assets were available.

DISCUSSION AND CONCLUSION

General surgery higher surgical trainees receive less than 50% of the operative exposure of urology higher surgical trainees in emergency scrotal surgery, which has important implications for curriculum competence development and patient safety.

Trauma and Orthopedic Surgery Curriculum Concordance: An Operative Learning Curve Trajectory Perspective

INTRODUCTION

Certification of completion of training in Trauma and Orthopedic (T&O) surgery in the UK requires the demonstration of operative competence in 12 index procedures, achieved through attaining a level 4 consultant-validated procedure-based assessment (PBA). The aim of this study was to evaluate the trajectory of operative learning curves related to PBA performance with respect to operative caseload and training time.

DESIGN

Logbook data from consecutive 24 higher T&O trainees were compared with PBA evaluations to determine the relationship between PBA level, operative experience, training time, and indicative numbers. Learning curve gradients were calculated using trigonometry related to operative experience and training time.

SETTING

A higher surgical orthopedic training program serving a single UK (Wales) Deanery.

PARTICIPANTS

Twenty-four consecutive higher T&O surgery trainees.

RESULTS

Median caseload to achieve level 4 competences ranged from 9 (interquartile range 6-12) for tension band wiring (olecranon or patella) to 101 (61-127) for arthroscopy, with significant variation between all 12 procedures (p < 0.001). Median number of PBAs to reach level 4 competences was 4 (2-6) with significant variation between procedures (p < 0.001). Median learning curve gradients to achieve level 4 competence for tension band wiring were 68.2° and 33.7° by caseload and training time respectively, compared with 12.2° and 45° for arthroscopy, with significant learning curve variation for all procedures related to caseload between first level 3 and first level 4 PBA (p < 0.001). Competence ratios were <1 (median 0.99, range 0.70-2.53) for 6 of the 12 indicative procedures.

CONCLUSIONS

Significant learning curve trajectory variance was observed, with discrepancies between indicative operative numbers and the point at which competence was judged achieved. Numbers of index operations to achieve certification of completion of training warrant further examination.

Accreditation of endocrine surgery units

BACKGROUND/PURPOSE

A key measure to maintain and improve the quality of healthcare is the formal accreditation of provider units. The European Society of Endocrine Surgeons (ESES) therefore proposes a system of accreditation for endocrine surgical centers in Europe to supplement existing measures that promote high standards in the practice in endocrine surgery.

METHODS

A working group analyzed the current healthcare situation in the field of endocrine surgery in Europe. Two surveys were distributed to ESES members to acquire information about the structure, staffing, caseload, specifications, and technology available to endocrine surgery units. Further data were sought on tracer diagnoses for quality standards, training provision, and research activity. Existing accreditation models related to endocrine surgery were included in the analysis.

RESULTS

The analysis of existing accreditation models, available evidence, and survey results suggests that a majority of ESES members aspire to a two-level model (termed competence and reference centers), sub-divided into those providing neck endocrine surgery and those providing endocrine surgery. Criteria for minimum caseload, number and certification of staff, unit structure, on-site collaborating disciplines, research activities, and training capacity for competence center accreditation are proposed. Lastly, quality indicators for distinct tracer diagnoses are defined.

CONCLUSIONS

Differing healthcare structures, existing accreditation models, training models, and varied case volumes across Europe are barriers to the conception and implementation of a pan-European accreditation model. However, there is consensus on accepted standards required for accrediting an ESES competence center. These will serve as a basis for first-stage accreditation of endocrine surgery units.

Variations in competencies needed to complete surgical training

Background

This study aimed to analyse the degree of relative variation in specialty-specific competencies required for certification of completion of training (CCT) by the UK Joint Committee on Surgical Training.

Methods

Regulatory body guidance relating to operative and non-operative surgical skill competencies required for CCT were analysed and compared.

Results

Wide interspecialty variation was demonstrated in the required minimum number of logbook cases (median 1201 (range 60-2100)), indexed operations (13 (5-55)), procedure-based assessments (18 (7-60)), publications (2 (0-4)), communications to learned associations (0 (0-6)) and audits (4 (1-6)). Mandatory courses across multiple specialties included: Training the Trainers (10 of 10 specialties), Advanced Trauma Life Support (6 of 10), Good Clinical Practice (9 of 10) and Research Methodologies (8 of 10), although no common accord was evident.

Discussion

Certification guidelines for completion of surgical training were inconsistent, with metrics related to minimum operative caseload and academic reach having wide variation.

Prospective Cohort Study of Haptic Virtual Reality Laparoscopic Appendicectomy Learning Curve Trajectory

Background: Simulation training is strongly advocated by 24/7 risk-rich professions because swift learning curve inflection point attainment delivers earlier competence; the left-shift effect. The aim of this study was to determine the value of haptic laparoscopic virtual reality simulation, by iterative benchmark exercise (n = 8), before simulated laparoscopic appendicectomy (SLA); the hypothesis was that favorable benchmark learning curve trajectories would be associated with improved SLA competence when compared with consultant expert performance. Methods: A 28-trainee cohort completed 1349 Laparoscopic Haptic Virtual Reality Skills (LHVRS) tasks, during which 19 ergonomic variables were assessed by virtual interface, including force feedback (Surgicalscience.com), before 153 SLAs. Primary outcome measure was SLA composite competence score related to six consultant trainer experts. Results: Of the eight LHVRS tasks, the three with the steepest learning curve trajectories correlated with better median overall SLA competence scores, namely tissue grasping/lifting (rho = 0.362, P = .049), fine dissection (rho = 0.388, P = .028), and camera navigation (rho = 0.518, P = .007); fine dissection was the only haptic laparoscopic virtual reality simulation task that predicted a SLA score within a Youden index defined, 70% of the consultant expert level (area under curve [AUC] = 0.803, P = .028). A significant SLA learning curve emerged, with a learning curve trajectory inflection point at the fourth SLA attempt (first SLA 30.5% versus fourth SLA score 76.0%, gradient 76°, P = .010). Conclusion: Learning curve trajectory can be measured, influenced, and accelerated significantly; a pronounced left-shift effect, with translational potential for enhanced shorter training time and improved patient safety.

Defining the characteristics of certified hernia centers in Italy: The Italian society of hernia and abdominal wall surgery workgroup consensus on systematic reviews of the best available evidences

BACKGROUND

The terms "Hernia Center" (HC) and Hernia Surgeon" (HS) have gained more and more popularity in recent years. Nevertheless, there is lack of protocols and methods for certification of their activities and results. The Italian Society of Hernia and Abdominal Wall Surgery proposes a method for different levels of certification.

METHODS

The national board created a commission, with the task to define principles and structure of an accreditation program. The discussion of each topic was preceded by a Systematic Review, according to PRISMA Guidelines and Methodology. In case of lack or inadequate data from literature, the parameter was fixed trough a Commission discussion.

RESULTS

The Commission defined a certification process including: "FLC - First level Certification": restricted to single surgeon, it is given under request and proof of a formal completion of the learning curve process for the basic procedures and an adequate year volume of operations. "Second level certification": Referral Center for Abdominal Wall Surgery. It is a public or private structure run by at least two already certified and confirmed FLC surgeons. "Third level certification": High Specialization Center for Abdominal Wall Surgery. It is a public or private structure, already confirmed as Referral Centers, run by at least three surgeons (two certified and confirmed with FLC and one research fellow in abdominal wall surgery). Both levels of certification have to meet the Surgical Requirements and facilities criteria fixed by the Commission.

CONCLUSION

The creation of different types of Hernia Centers is directed to create two different entities offering the same surgical quality with separate mission: the Referral Center being more dedicated to clinical and surgical activity and High Specialization Centers being more directed to scientific tasks.
