RESUMEN
BACKGROUND: The learning curve in paediatric oesophagogastroduodenoscopy (OGD) is unknown. Using ≥95% D2 (second part of the duodenum) intubation rates as a marker of technical competency, we conducted learning curve analyses to identify when trainees achieve competency in paediatric OGD. Factors associated with competency were also evaluated. METHODS: This nationwide study analysed data from paediatric OGD procedures prospectively entered into the UK endoscopy training e-portfolio between 2014 and 2018. Moving average and learning curve cumulative summation analyses were performed to determine procedural numbers required to achieve ≥95% D2 intubation rates. Factors associated with D2 intubation were assessed using a multivariable binary logistic regression approach. RESULTS: A total of 8929 procedures performed by 61 trainees were identified. These 61 trainees had recorded a mean of 124.6 procedures (range 22-571, interquartile range 165). By moving average analysis, 95% D2 intubation was achieved after 79 procedures. By learning curve cumulative summation analysis, 81.6% of trainees were competent after 100 procedures. Multivariable factors associated with unassisted procedural completion included: lifetime procedure count (Pâ<â0.001), higher trainee seniority (Pâ<â0.001), patient age (Pâ=â0.002), outpatient status (Pâ<â0.001), and attendance at a national Basic Skills OGD course (Pâ=â0.011). CONCLUSIONS: This study demonstrates that, on average, 79 procedures in paediatric OGD are required to attain the competency outcome of ≥95% D2 intubation rates. By 100 procedures, 81.6% of our sample had achieved ≥95% D2 intubation. The minimum procedural count of 100 set by the UK and international training programmes can be used alongside existing objective assessment measures to safeguard competency within a training cohort.

BACKGROUND: Validated competency assessment tools and the data supporting milestone development during gastroscopy training are lacking. We aimed to assess the validity of the formative direct observation of procedural skills (DOPS) assessment tool in diagnostic gastroscopy and study competency development using DOPS. METHODS: This was a prospective multicentre (N = 275) analysis of formative gastroscopy DOPS assessments. Internal structure validity was tested using exploratory factor analysis and reliability estimated using generalisability theory. Item and global DOPS scores were stratified by lifetime procedure count to define learning curves, using a threshold determined from receiver operator characteristics (ROC) analysis. Multivariable binary logistic regression analysis was performed to identify independent predictors of DOPS competence. RESULTS: In total, 10086 DOPS were submitted for 987 trainees. Exploratory factor analysis identified three distinct item groupings, representing 'pre-procedure', 'technical', and 'post-procedure non-technical' skills. From generalisability analyses, sources of variance in overall DOPS scores included trainee ability (31%), assessor stringency (8%), assessor subjectivity (18%), and trainee case-to-case variation (43%). The combination of three assessments from three assessors was sufficient to achieve the reliability threshold of 0.70. On ROC analysis, a mean score of 3.9 provided optimal sensitivity and specificity for determining competency. This threshold was attained in the order of 'pre-procedure' (100-124 procedures), 'technical' (150-174 procedures), 'post-procedure non-technical' skills (200-224 procedures), and global competency (225-249 procedures). Higher lifetime procedure count, DOPS count, surgical trainees and assessors, higher trainee seniority, and lower case difficulty were significant multivariable predictors of DOPS competence. CONCLUSION: This study establishes milestones for competency acquisition during gastroscopy training and provides validity and reliability evidence to support gastroscopy DOPS as a competency assessment tool.

RESUMEN
BACKGROUND: Direct Observation of Procedural Skills (DOPS) is an established competence assessment tool in endoscopy. In July 2016, the DOPS scoring format changed from a performance-based scale to a supervision-based scale. We aimed to evaluate the impact of changes to the DOPS scale format on the distribution of scores in novice trainees and on competence assessment. METHODS: We performed a prospective, multicenter (nâ=â276), observational study of formative DOPS assessments in endoscopy trainees with ≤â100 lifetime procedures. DOPS were submitted in the 6-months before July 2016 (old scale) and after (new scale) for gastroscopy (nâ=â2998), sigmoidoscopy (nâ=â1310), colonoscopy (nâ=â3280), and polypectomy (nâ=â631). Scores for old and new DOPS were aligned to a 4-point scale and compared. RESULTS: 8219 DOPS (43â% new and 57â% old) submitted for 1300 trainees were analyzed. Compared with old DOPS, the use of the new DOPS was associated with greater utilization of the lowest score (2.4â% vs. 0.9â%; Pâ<â0.001), broader range of scores, and a reduction in competent scores (60.8â% vs. 86.9â%; Pâ<â0.001). The reduction in competent scores was evident on subgroup analysis across all procedure types (Pâ<â0.001) and for each quartile of endoscopy experience. The new DOPS was superior in characterizing the endoscopy learning curve by demonstrating progression of competent scores across quartiles of procedural experience. CONCLUSIONS: Endoscopy assessors applied a greater range of scores using the new DOPS scale based on degree of supervision in two cohorts of trainees matched for experience. Our study provides construct validity evidence in support of the new scale format.

Background and study aims Socioeconomic deprivation has long been associated with many gastrointestinal diseases, yet its influence on esophagogastroduodenoscopy (EGD) diagnosis has not been evaluated. The aim of this study was to investigate the influence of deprivation on outcomes of EGD irrespective of referral reason. Patients and methods Two thousand consecutive patients presenting to four Health Boards in Wales beginning in June 2019 were studied retrospectively with deprivation scores calculated using the Wales Indices of Multiple Deprivation (WIMD). Patients were subclassified into quintiles for analysis (Q1 most, Q5 least deprived). Results Inhabitants of the most deprived areas were more likely to be diagnosed with peptic ulcer (Q1 7.9%, Q5 4.7%; odds ratio [OR] 0.498, P =0.018), severe esophagitis (LA4, Q1 2.7% v Q5 0%, OR 0.089, P 0.002), Helicobacter pylori infection (Q1 5.4%, Q5 1.7%; OR 0.284, P =0.002), but less likely to be diagnosed with Barrett's esophagus (Q1 6.3% v Q5 12.3%, OR 2.146, P =0.004) than those from the least deprived areas. New cancer diagnoses numbered 53 and were proportionately higher after presentation for urgent suspected cancer (USC, n=35, 4.6%) than for routine referrals (n=3, 0.6%, P < 0.001). Deprivation was associated with more advanced stage cancer (stage III Q1 16.7% v Q5 5.6%, OR 0.997, P =0.006: stage IV Q1 16.7% v Q2 38.9% v Q5 22.2%, OR 0.998, P =0.049). Conclusions Deprivation was associated with two-fold more peptic ulcer disease, three-fold more H. pylori infection, and 12-fold more severe esophagitis, and more advanced cancer stage.
RESUMEN
INTRODUCTION: COVID-19 has caused severe disruption to clinical services in Bangladesh but the extent of this, and the impact on healthcare professionals is unclear. We aimed to assess the perceived levels of anxiety, depression and burnout among doctors and nurses during COVID-19 pandemic. METHODS: We undertook an online survey using RedCap, directed at doctors and nurses across four institutions in Bangladesh (The Sheikh Russel Gastro Liver Institute & Hospital (SRNGIH), Dhaka Medical College Hospital (DMCH), Mugda Medical College Hospital (MMCH) and M Abdur Rahim Medical College (MARMC) Hospital). We collected information on demographics, awareness of well-being services, COVID-19-related workload, as well as anxiety, depression and burnout using two validated questionnaires: the Hospital Anxiety and Depression Scale (HADS) and the Maslach Burnout Inventory (MBI). RESULTS: Of the 3000 participants approached, we received responses from 2705 (90.2%). There was a statistically significant difference in anxiety, depression and burnout scores across institutions (p<0.01). Anxiety, depression and burnout scores were statistically worse in COVID-19 active staff compared with those not working on COVID-19 activities (p<0.01 for HADS anxiety and depression and MBI emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA)). Over half of the participants exhibited some level of anxiety (SRNGIH: 52.2%; DMCH: 53.9%; MMCH: 61.3%; MARMC: 68%) with a high proportion experiencing depression (SRNGIH: 39.5%; DMCH: 38.7%; MMCH: 53.7%; MARMC: 41.1%). Although mean burnout scores were within the normal range for each institution, a high proportion of staff (almost 20% in some instances) were shown to be classified as experiencing burnout by their EE, DP and PA scores. CONCLUSION: We identified a high prevalence of perceived anxiety, depression and burnout among doctors and nurses during the COVID-19 pandemic. This was worse in staff engaged in COVID-19-related activities. These findings could help healthcare organisations to plan for future similar events.

The pathogenesis of duodenal tumors in the inherited tumor syndromes familial adenomatous polyposis (FAP) and MUTYH-associated polyposis (MAP) is poorly understood. This study aimed to identify genes that are significantly mutated in these tumors and to explore the effects of these mutations. Whole exome and whole transcriptome sequencing identified recurrent somatic coding variants of phosphatidylinositol N-acetylglucosaminyltransferase subunit A (PIGA) in 19/70 (27%) FAP and MAP duodenal adenomas, and further confirmed the established driver roles for APC and KRAS. PIGA catalyzes the first step in glycosylphosphatidylinositol (GPI) anchor biosynthesis. Flow cytometry of PIGA-mutant adenoma-derived and CRISPR-edited duodenal organoids confirmed loss of GPI anchors in duodenal epithelial cells and transcriptional profiling of duodenal adenomas revealed transcriptional signatures associated with loss of PIGA. IMPLICATIONS: PIGA somatic mutation in duodenal tumors from patients with FAP and MAP and loss of membrane GPI-anchors may present new opportunities for understanding and intervention in duodenal tumorigenesis.

Introduction: In the UK, endoscopy certification is awarded when trainees attain minimum competency standards for independent practice. A national evidence-based review was undertaken to update and develop standards and recommendations for colonoscopy training and certification. Methods: Under the oversight of the Joint Advisory Group (JAG), a modified Delphi process was conducted between 2019 and 2020 with multisociety expert representation. Following literature review and Grading of Recommendations, Assessment, Development and Evaluations appraisal, recommendation statements on colonoscopy training and certification were formulated and subjected to anonymous voting to obtain consensus. Accepted statements were peer reviewed by JAG and relevant stakeholders for incorporation into the updated colonoscopy certification pathway. Results: In total, 45 recommendation statements were generated under the domains of: definition of competence (13), acquisition of competence (20), assessment of competence (8) and postcertification support (4). The consensus process led to revised criteria for colonoscopy certification, comprising: (1) achieving key performance indicators defined within British Society of Gastroenterology standards (ie, unassisted caecal intubation rate >90%, rectal retroversion >90%, polyp detection rate >15%+, polyp retrieval rate >90%, patient comfort <10% with moderate-severe discomfort); (2) minimum procedure count 280+; (3) performing 15+ procedures over the preceding 3 months; (4) attendance of the JAG Basic Skills in Colonoscopy course; (5) terminal ileal intubation rates of 60%+ in inflammatory bowel disease; (6) satisfying requirements for formative direct observation of procedure skills (DOPS) and direct observation of polypectomy skills (Size, Morphology, Site, Access (SMSA) level 2); (7) evidence of reflective practice as documented on the JAG Endoscopy Training System reflection tool; (8) successful performance in summative DOPS. Conclusion: The UK standards for training and certification in colonoscopy have been updated, culminating in a single-stage certification process with emphasis on polypectomy competency (SMSA Level 2+). These standards are intended to support training, improve standards of colonoscopy and polypectomy, and provide support to the newly independent practitioner.
RESUMEN
Introduction: Joint Advisory Group (JAG) certification in endoscopy is awarded when trainees attain minimum competency standards for independent practice. A national evidence-based review was undertaken to update standards for training and certification in flexible sigmoidoscopy (FS). Methods: A modified Delphi process was conducted between 2019 and 2020 with multisociety representation from experts and trainees. Following literature review and Grading of Recommendations, Assessment, Development and Evaluations appraisal, recommendation statements on FS training and certification were formulated and subjected to anonymous voting to obtain consensus. Accepted statements were peer-reviewed by national stakeholders for incorporation into the JAG FS certification pathway. Results: In total, 41 recommendation statements were generated under the domains of: definition of competence (13), acquisition of competence (17), assessment of competence (7) and postcertification support (4). The consensus process led to revised criteria for colonoscopy certification, comprising: (A) achieving key performance indicators defined within British Society of Gastroenterology standards (ie, rectal retroversion >90%, polyp retrieval rate >90%, patient comfort <10% with moderate-severe discomfort); (B) minimum procedure count ≥175; (C) performing 15+ procedures over the preceding 3 months; (D) attendance of the JAG Basic Skills in Lower gastrointestinal Endoscopy course; (E) satisfying requirements for formative direct observation of procedural skill (DOPS) and direct observation of polypectomy skill (SMSA level 1); (F) evidence of reflective practice as documented on the JAG Endoscopy Training System reflection tool and (G) successful performance in summative DOPS. Conclusion: The UK standards for training and certification in FS have been updated to support training, uphold standards in FS and polypectomy, and provide support to the newly independent practitioner.
RESUMEN
BACKGROUND: Simulation is a useful adjunct to skills-based training. It potentially avoids risk to patients during training and development of basic interventional techniques. This may be of particular relevance in colonoscopy where the learning curve can be long. Several endoscopic devices exist that simulate colonoscopy for training purposes. This study was designed to review the evidence for the validity of these simulators. METHODS: MEDLINE (1947 to present), PubMed, Embase classic + Embase, the metaRegister of Controlled Trials, and the Education Resources Information Center (ERIC) were searched for studies validating colonoscopy simulators. For each study, we recorded the type of simulator used, the tasks assessed, the endpoints reported, and the type of validity measured. Common endpoints between studies were compared, and the evidence was graded. RESULTS: Thirteen studies met the inclusion criteria. Construct validity was reported in five (41.7 %) studies for the Accutouch HT Immersion (cases 1, 3, and 4), four studies (33.3 %) for the GI mentor II (Simbionix) (Modules 1.1, 1.3, 1.7, 2.1, and 5), two studies (16.7 %) for the Olympus Endo Ts-1 2nd Generation, and one study for the Endo X bovine model. Face validity was reported for the Accutouch HT Immersion, the Olympus 2nd Generation, and the KAIST-Ewha. Content validity was reported for the all simulators, excluding the KAIST-Ewha. The only report of criterion validity was for the Endo X bovine model. CONCLUSION: Evidence exists to support the face, content, and construct validity of several virtual reality colonoscopy simulators for specific diagnostic and therapeutic modules with selected endpoints. One study demonstrates content, construct, and criterion validity for an ex vivo animal platform. Further work is needed to demonstrate the criterion validity of all devices.

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), 35.0â% short of Joint Advisory Group (JAG) standard (nâ=â20, Pâ=â0.001, 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) (Pâ<â0.001, -0.61). Esophagogastroduodenoscopy median KPI: J maneuver 94â% (90-96), D2 intubation 93â% (91-96); Colonoscopy KPI: cecal intubation 82â% (72-90), polyp detection rate 25â% (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.
RESUMEN
Background and study aims Virtual reality endoscopic simulation training has the potential to expedite competency development in novice trainees. However, simulation platforms must be realistic and confer face validity. This study aimed to determine the face validity of high-fidelity virtual reality simulation (EndoSim, Surgical Science, Gothenburg), and establish benchmark metrics to guide the development of a Simulation Pathway to Improve Competency in Endoscopy (SPICE). Methods A pilot cohort of four experts rated simulated exercises (Likert scale score 1-5) and following iterative development, 10 experts completed 13 simulator-based endoscopy exercises amounting to 859 total metric values. Results Expert metric performance demonstrated equivalence ( P â=â0.992). In contrast, face validity of each exercise varied among experts (median 4 (interquartile range [IQR] 3-5), P â<â0.003) with Mucosal Examination receiving the highest scores (median 5 [IQR 4.5-5], P â=â1.000) and Loop Management and Intubation exercises receiving the lowest scores (median 3 [IQR 1-3], P â<â0.001, P â=â0.004), respectively. The provisional validated SPICE comprised 13 exercises with pass marks and allowance buffers defined by median and IQR expert performance. Conclusions EndoSim Face Validity was very good related to early scope handling skills, but more advanced competencies and translation of acquired clinical skills require further research within an established training program. The existing training deficit with superadded adverse effects of the COVID pandemic make this initiative an urgent priority.

RESUMEN
Background and study aims Despite the high-risk nature of endoscopic retrograde cholangiopancreatography (ERCP), a robust and standardized credentialing process to ensure competency before independent practice is lacking worldwide. On behalf of the Joint Advisory Group (JAG), we aimed to develop evidence-based recommendations to form the framework of ERCP training and certification in the UK. Methods Under the oversight of the JAG, a modified Delphi process was conducted with stakeholder representation from the British Society of Gastroenterology, Association of Upper Gastrointestinal Surgeons, trainees and trainers. Recommendations on ERCP training and certification were formulated after formal literature review and appraised using the GRADE tool. These were subjected to electronic voting to achieve consensus. Accepted statements were peer-reviewed by JAG and relevant Specialist Advisory Committees before incorporation into the ERCP certification pathway. Results In total, 27 recommendation statements were generated for the following domains: definition of competence (9 statements), acquisition of competence (8 statements), assessment of competence (6 statements) and post-certification support (4 statements). The consensus process led to the following criteria for ERCP certification: 1) performingâ≥â300 hands-on procedures; 2) attending a JAG-accredited ERCP skills course; 3) in modified Schutz 1-2 procedures: achieving native papilla cannulation rate ≥80%, complete bile duct clearanceâ≥â70â%, successful stenting of distal biliary stricturesâ≥â75â%, physically unassisted inâ≥â80â% of cases; 4) 30-day post-ERCP pancreatitis rates ≤5â%; and 5) satisfactory performance in formative and summative direct observation of procedural skills (DOPS) assessments. Conclusions JAG certification in ERCP has been developed following evidence-based consensus to quality assure training and to ultimately improve future standards of ERCP practice.
RESUMEN
The British Society of Gastroenterology (BSG) and the Bangladesh Gastroenterology Society (BGS) have collaborated on an endoscopy training programme, which has grown up over the past decade from a small scheme borne out of the ideas of consultant gastroenterologists in Swansea, South Wales (United Kingdom) to improve gastroenterology services in Bangladesh to become a formalised training programme with broad reach. In this article, we document the socioeconomic and historical problems that beset Bangladesh, the current training needs of doctors and how the BSG-BGS collaboration has made inroads into changing outcomes both for gastroenterologists in Bangladesh, but also for the populations they serve.
RESUMEN
BACKGROUND: Pre-clinical simulation-based training (SBT) in endoscopy has been shown to augment trainee performance in the short-term, but longer-term data are lacking. AIM: To assess the impact of a two-day gastroscopy induction course combining theory and SBT (Structured PRogramme of INduction and Training - SPRINT) on trainee outcomes over a 16-mo period. METHODS: This prospective case-control study compared outcomes between novice SPRINT attendees and controls matched from a United Kingdom training database. Study outcomes comprised: (1) Unassisted D2 intubation rates; (2) Procedural discomfort scores; (3) Sedation practice; (4) Time to 200 procedures; and (5) Time to certification. RESULTS: Total 15 cases and 24 controls were included, with mean procedure counts of 10 and 3 (P = 0.739) pre-SPRINT. Post-SPRINT, no significant differences between the groups were detected in long-term D2 intubation rates (P = 0.332) or discomfort scores (P = 0.090). However, the cases had a significantly higher rate of unsedated procedures than controls post-SPRINT (58% vs 44%, P = 0.018), which was maintained over the subsequent 200 procedures. Cases tended to perform procedures at a greater frequency than controls in the post-SPRINT period (median: 16.2 vs 13.8 per mo, P = 0.051), resulting in a significantly greater proportion of cases achieving gastroscopy certification by the end of follow up (75% vs 36%, P = 0.017). CONCLUSION: In this pilot study, attendees of the SPRINT cohort tended to perform more procedures and achieved gastroscopy certification earlier than controls. These data support the role for wider evaluation of pre-clinical induction involving SBT.
RESUMEN
The Joint Advisory Group on Gastrointestinal Endoscopy (JAG) was initially established in 1994 to standardise endoscopy training across specialties. Over the last two decades, the position of JAG has evolved to meet its current role of quality assuring all aspects of endoscopy in the UK to provide the highest quality, patient-centred care. Drivers such as changes to healthcare agenda, national audits, advances in research and technology and the advent of population-based cancer screening have underpinned this shift in priority. Over this period, JAG has spearheaded various quality assurance initiatives with support from national stakeholders. These have led to the achievement of notable milestones in endoscopy quality assurance, particularly in the three major areas of: (1) endoscopy training, (2) accreditation of endoscopy services (including the Global Rating Scale), and (3) accreditation of screening endoscopists. These developments have changed the landscape of UK practice, serving as a model to promote excellence in endoscopy. This review provides a summary of JAG initiatives and assesses the impact of JAG on training and endoscopy services within the UK and beyond.
RESUMEN
Introduction In the UK, endoscopy certification is administered by the Joint Advisory Group on Gastrointestinal Endoscopy (JAG). Since 2011, certification for upper and lower gastrointestinal endoscopy has been awarded via a national (JETS) e-portfolio to the main training specialties of: gastroenterology, gastrointestinal surgeons (GS) and non-medical endoscopists (NME). Trends in endoscopy certification and differences between trainee specialties were analyzed. Methods This prospective UK-wide observational study identified trainees awarded gastroscopy, sigmoidoscopy, colonoscopy (provisional and full) certification between June 2011â-â2017. Trends in certification, procedures and time-to-certification, and key performance indicators (KPIs) in the 3-month pre- and post-certification period were compared between the three main training specialties. Results Three thousand one hundred fifty-seven endoscopy-related certifications were awarded to 1928 trainees from gastroenterology (52.3â%), GS (28.4â%) and NME (16.5 â%) specialties. During the study period, certification numbers increased for all modalities and specialties, particularly NME trainees. For gastroscopy and colonoscopy, procedures-to-certification were lowest for GS ( P â<â0.001), whereas time-to-certification was consistently shortest in NMEs ( P â<â0.001). A post-certification reduction in mean cecal intubation rate (95.2â% to 93.8â%, P â<â0.001) was observed in colonoscopy, and D2 intubation (97.6â% to 96.2 %, P â<â0.001) and J-maneuver (97.3â% to 95.8â%, P â<â0.001) in gastroscopy. Overall, average pre- and post-certification KPIs still exceeded national minimum standards. There was an increase in PDR for NMEs after provisional colonoscopy certification but a decrease in PDR for GS trainees after sigmoidoscopy and full colonoscopy certification. Conclusion Despite variations among trainee specialties, average pre- and post-certification KPIs for certified trainees met national standards, suggesting that JAG certification is a transparent benchmark which adequately safeguards competency in endoscopy training.
