Twelve tips for developing simulation-based mastery learning clinical skills checklists

Simulation-based mastery learning is a powerful educational paradigm that leads to high levels of performance through a combination of strict standards, deliberate practice, formative feedback, and rigorous assessment. Successful mastery learning curricula often require well-designed checklists that produce reliable data that contribute to valid decisions. The following twelve tips are intended to help educators create defensible and effective clinical skills checklists for use in mastery learning curricula. These tips focus on defining the scope of a checklist using established principles of curriculum development, crafting the checklist based on a literature review and expert input, revising and testing the checklist, and recruiting judges to set a minimum passing standard. While this article has a particular focus on mastery learning, with the exception of the tips related to standard setting, the general principles discussed apply to the development of any clinical skills checklist.

The Laparoscopy in Biliary Exploration Research and Training Initiative (LIBERTI) trial: simulator-based training for laparoscopic management of choledocholithiasis

BACKGROUND

Laparoscopic cholecystectomy with common bile duct exploration (LCBDE) is equivalent in safety and efficacy to endoscopic retrograde cholangiopancreatography (ERCP) plus laparoscopic cholecystectomy (LC) while decreasing number of procedures and length of stay (LOS). Despite these advantages LCBDE is infrequently utilized. We hypothesized that formal, simulation-based training in LCBDE would result in increased utilization and improve patient outcomes across participating institutions.

METHODS

Data was obtained from an on-going multi-center study in which simulator-based transcystic LCBDE training curricula were instituted for attending surgeons and residents. A 2-year retrospective review of LCBDE utilization prior to LCBDE training was compared to utilization up to 2 years after initiation of training. Patient outcomes were analyzed between LCBDE strategy and ERCP strategy groups using χ2, t tests, and Wilcoxon rank tests.

RESULTS

A total of 50 attendings and 70 residents trained in LCBDE since November 2020. Initial LCBDE utilization rate ranged from 0.74 to 4.5%, and increased among all institutions after training, ranging from 9.3 to 41.4% of cases. There were 393 choledocholithiasis patients analyzed using LCBDE (N = 129) and ERCP (N = 264) strategies. The LCBDE group had shorter median LOS (3 days vs. 4 days, p < 0.0001). No significant differences in readmission rates between LCBDE and ERCP groups (4.7% vs. 7.2%, p = 0.33), or in post-procedure pancreatitis (0.8% v 0.8%, p > 0.98). In comparison to LCBDE, the ERCP group had higher rates of bile duct injury (0% v 3.8%, p = 0.034) and fluid collections requiring intervention (0.8% v 6.8%, p < 0.009) secondary to cholecystectomy complications. Laparoscopic antegrade balloon sphincteroplasty had the highest technical success rate (87%), followed by choledochoscopic techniques (64%).

CONCLUSION

Simulator-based training in LCBDE results in higher utilization rates, shorter LOS, and comparable safety to ERCP plus cholecystectomy. Therefore, implementation of LCBDE training is strongly recommended to optimize healthcare utilization and management of patients with choledocholithiasis.

Powerful medical education improves health care quality and return on investment

INTRODUCTION

Powerful medical education (PME) involves the use of new technologies informed by the science of expertise that are embedded in laboratories and organizations that value evidence-based education and support innovation. This contrasts with traditional medical education that relies on a dated apprenticeship model that yields uneven results. PME involves an amalgam of features, conditions and assumptions, and contextual variables that comprise an approach to developing clinical competence grounded in education impact metrics including efficiency and cost-effectiveness.

METHODS

This article is a narrative review based on SANRA criteria and informed by realist review principles. The review addresses the PME model with an emphasis on mastery learning and deliberate practice principles drawn from the new science of expertise. Pub Med, Scopus, and Web of Science search terms include medical education, the science of expertise, mastery learning, translational outcomes, cost effectiveness, and return on investment. Literature coverage is comprehensive with selective citations.

RESULTS

PME is described as an integrated set of twelve features embedded in a group of seven conditions and assumptions and four context variables. PME is illustrated via case examples that demonstrate improved ventilator patient management learning outcomes compared to traditional clinical education and mastery learning of breaking bad news communication skills. Evidence also shows that PME of physicians and other health care providers can have translational, downstream effects on patient care practices, patient outcomes, and return on investment. Several translational health care quality improvements that derive from PME include reduced infections; better communication among physicians, patients, and families; exceptional birth outcomes; more effective patient education; and return on investment.

CONCLUSIONS

The article concludes with challenges to hospitals, health systems, and medical education organizations that are responsible for producing physicians who are expected to deliver safe, effective, and cost-conscious health care.

TAVAC: choledochoscopy disposable scopes, and the single-stage vs. two-stage approach to choledocholithiasis

BACKGROUND

Previous studies have been published evaluating the benefits and drawbacks of clearing the common bile duct of stones using a single-stage approach (LCBDE + LC) versus a two-stage approach (ERCP followed by LC). These studies have demonstrated that a single-stage approach offers similar outcomes and morbidities as a two-stage approach, with the added benefit of a lower cost and shorter length of stays. However, it is significant we understand why LCBDE is not commonly performed currently and also the lapse in surgical trainee exposure and competence in LCBDE. This paper aims to address the lapse in surgical trainee exposure to LCBDE, evaluate the scopes currently available to perform LCBDE, and review current data evaluating the risks and benefits of single-stage versus two-stage approaches to.

METHODS

We utilized PubMed to analyze all publications related to the various disposable scopes utilized to perform choledochoscopy. We also discuss the need for disposable scopes and how this new market niche is transforming the choledochoscopy space.

RESULTS

We analyzed the data related to single-stage and two-stage approach to choledocholithiasis. We noted an overall shorter length of stay and also decreased costs in favor of a single-stage approach.

CONCLUSION

A single-stage LCBDE is the most cost-effective treatment option for choledocholithiasis in patients with choledocholithiasis undergoing a cholecystectomy. In addition, single-stage approach is associated with shorter length of stay. Knowledge of the available choledochoscopes and tools available to surgeons to perform choledochoscopy is significant. The evidence does support the use of disposable choledochoscope from a cost and cross-contamination perspective. Additionally, efforts should be made to incorporate LCBDE into the teaching paradigm of surgical training programs.

A simulation curriculum for laparoscopic common bile duct exploration, balloon sphincterotomy, and endobiliary stenting: Associations with resident performance and autonomy in the operating room

BACKGROUND

Laparoscopic common bile duct exploration is safe and effective for managing choledocholithiasis, but laparoscopic common bile duct exploration is rarely performed, which threatens surgical trainee proficiency. This study tests the hypothesis that prior operative or simulation experience with laparoscopic common bile duct exploration is associated with greater resident operative performance and autonomy without adversely affecting patient outcomes.

METHODS

This longitudinal cohort study included 33 consecutive patients undergoing laparoscopic common bile duct exploration in cases involving postgraduate years 3, 4, and 5 general surgery residents at a single institution during the implementation of a laparoscopic common bile duct exploration simulation curriculum. For each of the 33 cases, resident performance and autonomy were rated by residents and attendings, the resident's prior operative and simulation experience were recorded, and patient outcomes were ascertained from electronic health records for comparison among 3 cohorts: prior operative experience, prior simulation experience, and no prior experience.

RESULTS

Operative approach was similar among cohorts. Overall morbidity was 6.1% and similar across cohorts. The operative performance scores were higher in prior experience cohorts according to both residents (3.0 [2.8-3.0] vs 2.0 [2.0-3.0]; P = .01) and attendings (3.0 [3.0-4.0]; P < .001). The autonomy scores were higher in prior experience cohorts according to both residents (2.0 [2.0-3.0] vs 2.0 [2.0-2.0]; P = .005) and attendings (2.5 [2.0-3.0] vs 2.0 [1.0-2.0]; P = .001). Prior simulation and prior operative experience had similar associations with performance and autonomy.

CONCLUSION

Simulation experience with laparoscopic common bile duct exploration was associated with greater resident operative performance and autonomy, with effects that mimic prior operative experience. This illustrates the potential for simulation-based training to improve resident operative performance and autonomy for laparoscopic common bile duct exploration.

Use of an ultrasound-guided intravenous catheter insertion simulation-based mastery learning curriculum to improve paediatric anaesthesia care

Background

We previously showed that an ultrasound-guided i.v. catheter insertion (USGIV) simulation-based mastery learning (SBML) curriculum improves the simulated USGIV skills of paediatric anaesthesiologists. It remains unclear if improvements in simulated USGIV skills translate to improved patient care.

Methods

A cohort study was conducted from August 2018 to August 2020 to evaluate paediatric anaesthesiologists' USGIV performance in the operating theatre before and after they participated in the USGIV SBML curriculum. Paediatric anaesthesiologists' use of ultrasound for successful i.v. insertion and first-attempt i.v. insertion success rate with ultrasound were compared before and after training.

Results

Twenty-nine paediatric anaesthesiologists completed training. Unadjusted analysis showed a significant increase in the percentage of i.v. catheters inserted with ultrasound for successful i.v. catheter insertion (9.5-14.5%; P<0.001) and first i.v. catheter insertion attempt success with ultrasound (5.5-8.9%; P<0.001) from before to after training. Multivariable regression analysis showed higher odds of ultrasound use for a successful i.v. catheter attempt (1.79; 95% confidence interval [CI]: 1.11-2.90; P=0.018) and first-attempt success with ultrasound (4.11; 95% CI: 2.02-8.37; P<0.001) after training.

Conclusions

After completing the USGIV SBML curriculum, paediatric anaesthesiologists increased their ultrasound use for successful i.v. catheter insertion and first-attempt success rate with ultrasound for patients in the operating theatre.

Transcystic Choledochoscopy Utilizing a Disposable Choledochoscope: How We Do It

BACKGROUND

Biliary disease is common occurrence and can make up a large portion of the practice of a general surgeon. Choledocholithasis is a common entity amongst those with biliary disease. Although modern trends favor endoscopic retrograde cholangiopancreatography (ERCP) and other imaging modalities for the diagnosis and management of choledocholithiasis, laparoscopic common bile duct exploration (LCBDE) is likely underutilized.

METHODS

A literature summary utilizing a PUBMED search was performed to provide an up-to-date account regarding the latest data on LCBDE. A video identifying and explaining the critical components of a LBCDE procedure is provided.

RESULTS

LCBDE is an underutilized procedure which offers equivalent clinical outcomes compared with ERCP along with a shorter length of stay and reduced costs. LCBDE is also noted to be an effective option for common bile duct stones in the setting of altered anatomy, such as a Roux-en-Y gastric bypass.

CONCLUSION

Although modern trends favor ERCP and other imaging modalities for the diagnosis and management of choledocholithiasis, LCBDE is likely underutilized by surgeons. LCBDE can provide many benefits to patients including avoidance of additional procedures, shorter length of stay, higher success rates, and less costs. Out video should act is a guide for those surgeons interested in implementation LCBDE in their practice.

Novel advances in surgery for Gallstone Disease

PURPOSE OF REVIEW

Examine recent advances in the treatment of patients with complex gallstone disease.

RECENT FINDINGS

Laparoscopic common bile duct exploration (LCBDE) has been shown to be an effective and safe treatment for choledocholithiasis, resulting in decreased hospital length of stay and costs when compared with ERCP plus laparoscopic cholecystectomy (LC). Novel simulator-based curricula have recently been developed to address the educational gap that has resulted in an underutilization of LCBDE. Patients with cholecystitis who are too ill to safely undergo LC have traditionally been treated with percutaneous cholecystostomy (PC). Endoscopic ultrasound (EUS) guided gallbladder drainage is a novel definitive treatment for such patients and has been shown to result in decreased complications and hospital readmissions compared to PC. The management of symptomatic gallstone disease during pregnancy has evolved over the last several decades. While it is now well established that laparoscopic procedures under general anesthesia are safe throughout a pregnancy, recent studies have suggested that laparoscopic cholecystectomy during the third trimester specifically may result in higher rates of preterm labor when compared with non-operative management. Finally, indocyanine green (ICG) fluorescence cholangiography is a novel imaging modality that has been used during laparoscopic cholecystectomy and may offer better visualization of biliary anatomy during dissection when compared with traditional intraoperative cholangiography. A number of recent technological, procedural, educational, and research innovations have enhanced and expanded treatment options for patients with complex gallstone disease.

Ultrasound-Guided Peripheral Intravenous Catheter Insertion Training Reduces Use of Midline Catheters in Hospitalized Patients With Difficult Intravenous Access

OBJECTIVES

Difficult intravenous (IV) access (DIVA) is a prevalent condition in the hospital setting and increases utilization of midline catheters (MCs) and peripherally inserted central catheters (PICCs). Ultrasound-guided peripheral intravenous (USGPIV) insertion is effective at establishing intravenous access in DIVA but remains understudied in the inpatient setting. We evaluated the effect of an USGPIV simulation-based mastery learning (SBML) curriculum for nurses on MC and PICC utilization for hospitalized patients.

METHODS

We performed a quasi-experimental observational study. We trained nurses across all inpatient units at a large tertiary care hospital. We queried the electronic medical record to compare PICC and MC utilization for patients with DIVA during 3 periods: before USGPIV SBML training (control), during pilot testing of the intervention, and during the SBML intervention. To account for variations in insertion practices over time, we performed an interrupted time series (ITS) analysis between 2 periods, the combined control and pilot periods and the intervention period.

RESULTS

One hundred forty-eight nurses completed USGPIV SBML training. Midline catheters inserted monthly per 1000 patient-days for DIVA decreased significantly from 1.86 ± 0.51 (control) to 2.31 ± 0.28 (pilot) to 1.33 ± 0.51 (intervention; P = 0.001). The ITS analysis indicated a significant intervention effect (P < 0.001). Peripherally inserted central catheters inserted monthly per 1000 patient-days for DIVA also significantly decreased over the study periods; however, the ITS failed to show an intervention effect as PICC insertions were already decreasing during the control period.

CONCLUSIONS

A hospital-wide USGPIV SBML curriculum for inpatient nurses was associated with a significant reduction in MCs inserted for DIVA.

Effect of Ventricular Assist Device Self-care Simulation-Based Mastery Learning on Driveline Exit Site Infections: A Pilot Study

BACKGROUND

Ventricular assist device simulation-based mastery learning (SBML) results in better patient and caregiver self-care skills compared with usual training.

OBJECTIVE

The aim of this study was to evaluate the effect of SBML on driveline exit site infections.

METHODS

We compared the probability of remaining infection free at 3 and 12 months between patients randomized to SBML or usual training.

RESULTS

The SBML-training group had no infections at 3 months and 2 infections at 12 months, yielding a Kaplan-Meier estimate of the probability of remaining infection free of 0.857 (95% confidence interval [CI], 0.692-1.00) at 12 months. The usual-training group had 6 infections at 3 months with no additional infections by 12 months. Kaplan-Meier estimates of remaining infection free at 3 and 12 months were 0.878 (95% CI, 0.758-1.00) and 0.748 (95% CI, 0.591-0.946), respectively. Time-to-infection distributions for SBML versus usual training showed a difference in 12-month infection rates of 0.109 (P = .07).

CONCLUSIONS

Ventricular assist device self-care SBML resulted in fewer 12-month infections.

CONCLUSIONS

Using SBML is effective to quickly train clinicians to competently perform simulated cricothyrotomy during a pandemic.

Contemporary management of concomitant gallstones and common bile duct stones: a survey of Spanish surgeons

BACKGROUND

Concomitant gallstones and common bile duct stones (CBDS) is a relatively frequent presentation. The optimal treatment remains controversial and the debate persists between two strategies. The one-stage approach: laparoscopic cholecystectomy with laparoscopic common bile duct exploration (LCBDE) has been shown to be equally safe and more cost-effective than the more traditional two-stage approach: endoscopic retrograde cholangiography followed by laparoscopic cholecystectomy (ERCP + LC). However, many surgeons worldwide still prefer the two-stage procedure. This survey evaluated contemporary management of CBDS in Spain and assessed the impact of surgeon and hospital factors on provision of LCBDE.

METHODS

A 25-item, web-based anonymous survey was sent to general surgeons members of the Spanish Surgeons Association. Descriptive statistics were applied to summarize results.

RESULTS

Responses from 305 surgeons across 173 Spanish hospitals were analyzed. ERCP is the initial approach for preoperatively suspected CBDS for 86% of surgeons. LCBDE is the preferred method for only 11% of surgeons and only 11% treat more than 10 cases per year. For CBDS discovered intraoperatively, 59% of respondents attempt extraction while 32% defer to a postoperative ERCP. The main reasons cited for not performing LCBDE were lack of equipment, training and timely availability of an ERCP proceduralist. Despite these barriers, most surgeons (84%) responded that LCBDE should be implemented in their departments.

CONCLUSIONS

ERCP was the preferred approach for CBDS for the majority of respondents. There remains limited use of LCBDE despite many surgeons indicating it should be implemented. Focused planning and resourcing of both training and operational demands are required to facilitate adoption of LCBDE as option for patients.

Addressing the gap in laparoscopic common bile duct exploration training for rural surgeons: imparting procedural ability is not enough

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) is an underutilized therapy for choledocholithiasis. The driving factors of this practice gap are poorly defined. We sought to evaluate the attitudes and practice patterns of surgeons who underwent training courses using an LCBDE simulator.

METHODS

Surgeons completed a half-day simulator-based LCBDE curriculum at national courses, including the American College of Surgeons Advanced Skills Training for Rural Surgeons and the Society of American Gastrointestinal and Endoscopic Surgeons annual meeting. Attitudes were assessed with Likert surveys immediately before and after curriculum completion. Follow-up surveys were distributed electronically.

RESULTS

159 surgeons completed training during six courses. Surgeon attitudes regarding the overall superiority of LCBDE vs. ERCP shifted towards favoring LCBDE after course participation (4.0 vs 3.3; Likert scale 1-5, p < 0.001). 44% of surgeons completed follow-up surveys at a mean of 3 years post-course. Surgeons remained confident in their ability to perform LCBDE, with only 14% rating their skill as a significant barrier to practice, as compared with 43% prior to course participation (p < 0.01). However, only 28% of surgeons saw an increase in LCBDE volume. Deficiencies in operating room (OR) staff knowledge and instrument availability were the most significant barriers to post-course practice implementation and were inversely correlated with LCBDE case volume (ρ = - 0.44 and - 0.47, both p < 0.01). Surgeons for whom OR staff knowledge of LCBDE was not a significant barrier performed nearly 4 times more LCBDE than those who rated staff knowledge as a moderate, strong, or complete barrier.

CONCLUSIONS

Surgeons trained at an LCBDE course retained long-term confidence in their procedural ability. Practice implementation was hindered by deficiencies in OR staff knowledge and instrument availability. Surgeons with knowledgeable operating room staff performed significantly more LCBDEs than those with less capable assistance. These barriers should be addressed in future curricula to improve procedural adoption.

Choledocholithiasis-a new clinical pathway

The incidence of cholecystectomy in children has increased considerably since the early 1990s. Management of gallbladder disease in children must include an awareness of choledocholithiasis treatment strategies. Both endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct exploration (open or laparoscopic) are accepted management techniques for choledocholithiasis. Laparoscopic cholecystectomy with preoperative or postoperative ERCP is at least a two-procedure process while cholecystectomy with laparoscopic common bile duct exploration (LCBDE) can provide definitive treatment in a single procedure under one anesthetic. Despite this, the trend over the last decade continues towards less LCBDE utilization in favor of ERCP. This trend has resulted in decreased familiarity with LCBDE by adult and pediatric surgeons and their trainees. Access to the necessary tools and education on the technical aspects can allow for successful single-stage treatment of choledocholithiasis by surgeons during laparoscopic cholecystectomy. This may include a pre-defined stepwise algorithm and understanding of all the equipment and resources necessary to perform a LCBDE. Ultimately, increased understanding of the equipment and procedural steps necessary for LCBDE will result in widened adoption of the technique and thus confer advantages to the patient such as decreased length of stay and fewer required anesthetics.

Application of technology to educational needs in surgery

Innovations in surgical education follow advancing clinical technology. New surgical methods have prompted demand for systematic methods to leverage computing power and internet tools to achieve proficiency-based training goals. Virtual reality, high-fidelity patient simulation, web-based resources to facilitate performance assessment, and telementoring have become mainstream practices, although patient outcomes benefits are not well studied. Remote virtual meeting and mentoring have had transformative effects on resident experiences, the full effects of which remain to be seen.

Simulation-Based Assessments and Graduating Neurology Residents' Milestones: Status Epilepticus Milestones

BACKGROUND

The American Board of Psychiatry and Neurology and the Accreditation Council for Graduate Medical Education (ACGME) developed Milestones that provide a framework for residents' assessment. However, Milestones do not provide a description for how programs should perform assessments.

OBJECTIVES

We evaluated graduating residents' status epilepticus (SE) identification and management skills and how they correlate with ACGME Milestones reported for epilepsy and management/treatment by their program's clinical competency committee (CCC).

METHODS

We performed a cohort study of graduating neurology residents from 3 academic medical centers in Chicago in 2018. We evaluated residents' skills identifying and managing SE using a simulation-based assessment (26-item checklist). Simulation-based assessment scores were compared to experience (number of SE cases each resident reported identifying and managing during residency), self-confidence in identifying and managing these cases, and their end of residency Milestones assigned by a CCC based on end-of-rotation evaluations.

RESULTS

Sixteen of 21 (76%) eligible residents participated in the study. Average SE checklist score was 15.6 of 26 checklist items correct (60%, SD 12.2%). There were no significant correlations between resident checklist performance and experience or self-confidence. The average participant's level of Milestone for epilepsy and management/treatment was high at 4.3 of 5 (SD 0.4) and 4.4 of 5 (SD 0.4), respectively. There were no significant associations between checklist skills performance and level of Milestone assigned.

CONCLUSIONS

Simulated SE skills performance of graduating neurology residents was poor. Our study suggests that end-of-rotation evaluations alone are inadequate for assigning Milestones for high-stakes clinical skills such as identification and management of SE.

Porcine Aorto-Renal Artery (PARA) model for laparoscopic transcystic common bile duct exploration: the evolution of a training model to meet new clinical needs

BACKGROUND

The transcystic approach to laparoscopic common bile duct exploration has gained popularity for the single-stage management of choledocholithiasis with concomitant gallstones. Our team previously described the use of a porcine aorta segment to simulate the common bile duct during laparoscopic skill training.

METHODS

With the advent of the transcystic approach as a contender for the first-line technique of accessing the common bile duct, we present an evolution of the laparoscopic training model using a Porcine Aorta-Renal Artery (PARA) specimen to simulate the structural integrity, dimensions and spatial distribution of both the human cystic and common bile ducts.

RESULTS

This training model allows the use of a choledochoscope for transcystic exploration of the biliary tree. It combines fidelity and reproducibility required for a simulated training model to offer experience in laparoscopic transcystic common bile duct exploration. Validation of the model was demonstrated by 21 surgeons who completed a questionnaire after performing the simulated procedure. In all sections assessing reliability, face validity and content validity of the model, mean rating scores were between 4 and 5 out of five (good or excellent).

CONCLUSIONS

We present the evolution of an established training model for laparoscopic common bile duct exploration which focusses the attention on the transcystic approach to the common bile duct and the use of lithotripsy techniques. The need for such a model reflects the shift in the current practice of the laparoendoscopic management of choledocholithiasis with concomitant gallstones from transductal to transcystic approach.

Short-term Retention of Patient and Caregiver Ventricular Assist Device Self-care Skills after Simulation-based Mastery Learning

Background

We developed a simulation-based mastery learning (SBML) curriculum that boosted self-care skills for patients with a ventricular assist device (VAD). In this study, we evaluated short-term skills retention.

Methods

We assessed skill retention among patients and caregivers who participated in VAD self-care SBML at a tertiary care center. We compared discharge skills tests (immediately after completing SBML) to 1- and 3-month follow-up tests to assess skill retention.

Results

Fifteen patients and 15 caregivers completed discharge and follow-up testing. Skills were largely retained at 1- and 3-months.

Conclusions

SBML results in short-term retention of VAD self-care skills.

Impact of Simulation-based Mastery Learning on Resident Skill Managing Mechanical Ventilators

Background: Caring for patients requiring mechanical ventilation is complex, and residents may lack adequate skill for managing these patients. Simulation-based mastery learning (SBML) is an educational model that trains clinicians to a high standard and can reduce complications. The mastery learning model has not been applied to ventilator management. Objective: The purpose of this study was to determine whether SBML, as compared with traditional training, is an effective strategy for teaching residents the skills necessary to manage patients requiring mechanical ventilation. Methods: We developed an SBML curriculum and a 47-item skills checklist to test ventilator management for patients with normal, restricted, and obstructed lung physiology. A minimum passing standard (MPS) on the checklist was set using the Mastery Angoff method. Residents rotating through the medical intensive care unit in Academic Year 2017-2018 were assigned to SBML or traditional training based on their medical intensive care unit team. The SBML group was pretested on a ventilator simulator using the skills checklist. They then received a 1.5-hour session (45 min didactic and 45 min deliberate practice on the simulator with feedback). At rotation completion, they were posttested on the simulator using the checklist until the MPS was met. Both SBML-trained and traditionally trained groups received teaching during daily bedside rounds and twice weekly didactic lectures. At rotation completion, traditionally trained residents were tested using the same skills checklist on the simulator. We compared pretest and posttest performance among SBML-trained residents and end of the rotation test performances between the SBML-trained and traditionally trained residents. Results: The MPS was set at 87% on the checklist. Fifty-seven residents were assigned to the SBML-trained group and 49 were assigned to the traditionally trained group. Mean checklist scores for SBML-trained residents improved from 51.4% (standard deviation [SD] = 17.5%) at pretest to 86.1% (SD = 7.6%) at initial posttest and 92.5% (SD = 3.7%) at final (mastery) posttest (both P < 0.001). Forty-two percent of residents required more than one attempt at the posttest to meet or exceed the MPS. At rotation completion, the traditionally trained residents had a mean test score of 60.9% (SD = 13.3%). Conclusion: SBML is an effective strategy to train residents on mechanical ventilator management. An SBML curriculum may augment traditional training methods to further equip residents to safely manage ventilated patients.

Use of a simulation-based mastery learning curriculum to improve ultrasound-guided vascular access skills of pediatric anesthesiologists

BACKGROUND

Pediatric vascular access is inherently challenging due to the small caliber of children's vessels. Ultrasound-guided intravenous catheter insertion has been shown to increase success rates and decrease time to cannulation in patients with difficult intravenous access. Although proficiency in ultrasound-guided intravenous catheter insertion is a critical skill in pediatric anesthesia, there are no published competency-based training curricula.

AIMS

The objective of this study was to evaluate the performance of pediatric anesthesiologists who participated in a novel ultrasound-guided intravenous catheter insertion simulation-based mastery learning curriculum.

METHODS

Pediatric anesthesia attendings, fellows, and rotating residents participated in the ultrasound-guided intravenous catheter insertion simulation-based mastery learning curriculum from August 2019 to February 2020. The 2-hour curriculum consisted of participants first undergoing a simulated skills pretest followed by watching a video on ultrasound-guided intravenous catheter insertion and deliberate practice on a simulator. Subsequently, all participants took a post-test and were required to meet or exceed a minimum passing standard. Those who were unable to meet the minimum passing standard participated in further practice until they could be retested and met this standard. We compared pre to post-test ultrasound-guided intravenous catheter insertion skills and self-confidence before and after participation in the curriculum.

RESULTS

Twenty-six pediatric anesthesia attendings, 12 fellows, and 38 residents participated in the curriculum. At pretest, 16/76 (21%) participants were able to meet or exceed the minimum passing standard. The median score on the pretest was 21/25 skills checklist items correct and improved to 24/25 at post-test (95% CI 3.0-4.0, P < .01). Self-confidence significantly improved after the course from an average of 3.2 before the course to a postcourse score of 3.9 (95% CI 0.5-0.9, P < .01; 1 = Not all confident, 5 = Very confident).

CONCLUSIONS

Simulation-based mastery learning significantly improved anesthesiologists' ultrasound-guided intravenous catheter insertion performance in a simulated setting.

Comparison of the safety and efficacy of single-stage endoscopic retrograde cholangiopancreatography plus laparoscopic cholecystectomy versus two-stage ERCP followed by laparoscopic cholecystectomy six-to-eight weeks later: A randomized controlled trial

INTRODUCTİON: Currently, the management of cholelithiasis in combination with choledocholithiasis involves endoscopic retrograde cholangiopancreatography (ERCP) followed by cholecystectomy. However, recently, early surgical approaches are becoming more common, even in the treatment of acute cholecystitis. METODS: Patients diagnosed as having cholelithiasis and choledocholithiasis between October 2017 and May 2019 were prospectively enrolled in the study in a randomized manner. Patients undergoing ERCP + LC (laparoscopic cholecystectomy) in the same session were assigned to group A (n = 39), those undergoing ERCP + LC in the same hospitalization period were assigned to group B (n = 43), and patients who underwent delayed cholecystectomy after ERCP were included in group C (n = 37). RESULT: A total of 119 patients (47 females and 72 males) were included in the study and divided into three groups. Statistical comparisons of the study groups showed a significant difference between the three groups in terms of the length of hospital stay (days) and total cost (p < 0.001). The total cost was significantly higher for patients in group C in comparison with those in groups A and B (p < 0.001). Compared with patients in groups A and B, there was statistically significant difference in the length of hospital stay for patients in group C (p < 0.001). CONCLUSİONS: Single-stage ERCP plus LC is a safe and feasible strategy for the management of cholelithiasis and choledocholithiasis, offering advantages of cost, shorter hospital stay, and total anesthesia time. The major advantage of ERCP and LC performed in the same session and during the same hospitalization is the absence of the risk of recurrent episodes of acute cholecystitis, which occur with delayed cholecystectomy.

A review of general surgery resident experience in common bile duct exploration in the ERCP era

BACKGROUND

Use of minimally invasive techniques for management of common bile duct (CBD) stones has led to declining number of CBD explorations (CBDE) performed at teaching and non-teaching institutions. We evaluate the impact of this decline on surgery training in bile duct procedures.

STUDY DESIGN

National operative data for general surgery residents (GSR) were examined from 2000 to 2018. Biliary operations including, cholecystectomy open and laparoscopic, and CBDE open and laparoscopic were evaluated for mean number of cases per graduating GSR.

RESULTS

Despite increases in number of GSR, case numbers for laparoscopic cholecystectomy increased 39% from 84 to 117, p < .00001, per GSR. Mean number of cases for open CBDE, however, decreased 74% from 2.7 to 0.7, p < .00001, per GSR and laparoscopic CBDE declined 22% from 0.9 to 0.7 per resident.

CONCLUSION

GSR operative case volume in CBDE has declined significantly creating a training deficiency for this complex skill. Novel simulation, including fresh cadavers, may offer the best option with high-fidelity, dynamic training to mitigate the loss of low volume, high acuity procedures.

Patient, Caregiver, and Clinician Perceptions of Ventricular Assist Device Self-care Education Inform the Development of a Simulation-based Mastery Learning Curriculum

BACKGROUND

Patients who undergo ventricular assist device (VAD) implantation and their caregivers must rapidly learn a significant amount of self-care skills and knowledge.

OBJECTIVE

The aim of this study was to explore patient, caregiver, VAD coordinator, and physician perspectives and perceptions of existing VAD self-care training to inform development of a simulation-based mastery learning (SBML) curriculum to teach patients and caregivers VAD self-care skills and knowledge.

METHODS

We conducted semistructured, in-person interviews with patients with a VAD, their caregivers, VAD coordinators, and physicians (cardiac surgeons, an infectious disease physician, and advanced heart failure cardiologists). We used a 2-cycle team-based iterative inductive approach to coding and analysis.

RESULTS

We interviewed 16 patients, 12 caregivers, 7 VAD coordinators, and 11 physicians. Seven major themes were derived from the interviews including (1) identification of critical curricular content, (2) need for standardization and assessment, (3) training modalities, (4) benefits of repetition, (5) piercing it all together, (6) need for refresher training, and (7) provision of training before implant.

CONCLUSIONS

Findings from this study suggest that SBML is a natural fit for the high-risk tasks needed to save VAD self-care. The 7 unique training-related themes derived from the qualitative data informed the design and development of a VAD SBML self-care curriculum.

Simulation-Based Mastery Learning Improves Patient and Caregiver Ventricular Assist Device Self-Care Skills: A Randomized Pilot Trial

BACKGROUND

No recognized standards exist for teaching patients and their caregivers ventricular assist device (VAD) self-care skills. We compared the effectiveness of a VAD simulation-based mastery learning (SBML) self-care training curriculum with usual VAD self-care training.

METHODS AND RESULTS

VAD patients and their caregivers were randomized to SBML or usual training during their implant hospitalization. The SBML group completed a pretest on 3 VAD self-care skills (controller, power source, and dressing change), then viewed videos and participated in deliberate practice on a simulator. SBML participants took a posttest and were required to meet or exceed a minimum passing standard for each of the skills. The usual training group completed the existing institutional VAD self-care teaching protocol. Before hospital discharge, the SBML and usual training groups took the same 3 VAD self-care skills tests. We compared demographic and clinical information, self-confidence, total participant training time, and skills performance between groups. Forty participants completed the study in each group. There were no differences in demographic and clinical information, self-confidence, or training time between groups. More participants in the SBML group met the minimum passing standard compared with the usual training group for controller (37/40 [93%] versus 25/40 [63%]; P=0.001), power source (36/40 [90%] versus 9/40 [23%]; P<0.001), and dressing change skills (19/20 [95%] versus 0/20; P<0.001).

CONCLUSIONS

SBML provided superior VAD self-care skills learning outcomes compared with usual training. This study has important implications for patients due to the morbidity and mortality associated with improper VAD self-care.

Surgical (Open and laparoscopic) management of large difficult CBD stones after different sessions of endoscopic failure: A retrospective cohort study

Objectives

For complicated common bile duct stones (CBDS) that cannot be extracted by endoscopic retrograde cholangiopancreatography (ERCP), management can be safely by open or laparoscopic CBD exploration (CBDE). The study aimed to assess these surgical procedures after endoscopic failure.

Methods

We analyzed 85 patients underwent surgical management of difficult CBDS after ERCP failure, in the period from 2013 to 2018.

Results

Sixty-seven (78.8%) and 18(21.2%) of our patients underwent single and multiple ERCP sessions respectively. An impacted large stone was the most frequent cause of ERCP failure (60%). Laparoscopic CBDE(LCBDE), open CBDE(OCBDE) and the converted cases were 24.7% (n = 21), 70.6% (n = 60), and 4.7% (n = 4) respectively. Stone clearance rate post LCBDE and OCBDE reached 95.2% and 95% respectively, Eleven (12.9%) of our patients had postoperative complications without mortality. By comparing LCBDE and OCBDE; there was a significant association between the former and longer operative time. On comparing, T-tube and 1ry CBD closure in both OCBDE and LCBDE, there was significantly longer operative time, and post-operative hospital stays in the former. Furthermore, in OCBDE group, choledocoscopy had an independent direction to 1ry CBD repair and significant association with higher stone clearance rate, shorter operative time, and post-operative hospital stay.

Conclusion

Large difficult CBDS can be managed either by open surgery or laparoscopically with acceptable comparable outcomes with no need for multiple ERCP sessions due to their related morbidities; furthermore, Open choledocoscopy has a good impact on stone clearance rate with direction towards doing primary repair that is better than T-tube regarding operative time and post-operative hospital stay.

Combination of serum gamma-glutamyltransferase and alkaline phosphatase in predicting the diagnosis of asymptomatic choledocholithiasis secondary to cholecystolithiasis

BACKGROUND

Gamma-glutamyltransferase (GGT) is one of the most important laboratory tests for the evaluation of liver damage. Through a long-term clinical observation of patients with secondary asymptomatic choledocholithiasis, we found that most patients had abnormal GGT serum levels.

AIM

To investigate the combination of serum GGT and alkaline phosphatase (ALP) in predicting the diagnosis of asymptomatic choledocholithiasis secondary to cholecystolithiasis.

METHODS

In this retrospective cohort study, the clinical data of 829 patients with cholecystolithiasis admitted to the Third Affiliated Hospital of Zunyi Medical College from August 2014 to August 2017 were collected. Among these patients, 151 patients had secondary asymptomatic choledocholithiasis and served as the observation group, and the remaining 678 cholecystolithiasis patients served as the control group. Serum liver function indexes were detected in both groups, and the receiver operating characteristic (commonly known as ROC) curves were constructed for markers showing statistical significances. The cutoff value, sensitivity, and specificity of each marker were calculated according to the ROC curves.

RESULTS

The overall incidence of asymptomatic choledocholithiasis secondary to cholecystolithiasis was 18.2%. The results of liver function indexes including serum aspartate aminotransferase, alanine aminotransferase, direct bilirubin and total bilirubin levels showed no significant differences between the two groups (P > 0.05). However, the serum GGT and ALP levels were significantly higher in the observation group than in the control group (P < 0.05). The ROC curve analysis showed that the area under the curve was 0.881 (95%CI: 0.830-0.932), 0.647 (95%CI: 0.583-0.711) and 0.923 (95%CI: 0.892-0.953) for GGT, ALP, and GGT + ALP, respectively. The corresponding cut-off values of GGT and ALP were 95.5 U/L and 151.5 U/L, sensitivity were 90.8% and 65.1%, and specificity were 83.6% and 59.8%, respectively. The sensitivity and specificity of GGT + ALP were 93.5% and 85.1%, respectively.

CONCLUSION

An abnormally elevated serum GGT level has an important value in the diagnosis of asymptomatic choledocholithiasis secondary to cholecystolithiasis. The combination of serum GGT and ALP has better diagnostic performance. As a convenient, rapid and inexpensive test, it should be applied in secondary asymptomatic choledocholithiasis routine screening.

The Effect of Judge Selection on Standard Setting Using the Mastery Angoff Method during Development of a Ventricular Assist Device Self-Care Curriculum

Background

Patients and caregivers need to perform ventricular assist device (VAD) self-care safely to help prevent complications (e.g., infection). We developed a VAD self-care simulation-based mastery learning (SBML) curriculum. We determined optimal minimum passing scores (MPSs) and evaluated effects of judge selection.

Methods

A multidisciplinary team created a VAD self-care SBML curriculum including simulated skills and knowledge examinations. Patients, caregivers, VAD coordinators, and physicians were expert judges who determined MPSs using the Mastery Angoff method.

Results

MPSs for the skills and knowledge examinations were high (range = 94-99% and 97% correct), respectively. Judges closely agreed on MPSs.

Conclusions

Stakeholders set stringent MPSs for high-stakes VAD self-care.

Laparoscopic Common Bile Duct Exploration Is a Safe and Effective Strategy for Elderly Patients

PURPOSE

Laparoscopic common bile duct exploration (LCBDE) has been widely used to remove common bile duct (CBD) stones. However, surgery is not considered as the first treatment choice for elderly patients with CBD stones because of the potential risk of postoperative complications. This study aims to evaluate the safety and efficiency of LCBDE for elderly patients.

METHODS

From April 2011 to October 2016, 265 consecutive patients underwent LCBDE. We performed a retrospective study and divided these patients into 2 groups. The younger group was younger than 70 years old (n = 179), and the elderly group was 70 years old or older (n = 86). We compared patient demographics, clinical characteristics, intraoperative parameters, postoperative complications, and incidence of recurrent stone between the 2 groups.

RESULTS

The elderly patients had higher preoperative morbidity of chronic diseases, such as pulmonary diseases, heart diseases, arterial hypertension, and abdominal operation history ( P < .05). There were no significant differences between the 2 groups in terms of operation time, intraoperative blood loss, conversion rate to open surgery, total cost, overall complications, and incidence of recurrent stone ( P > .05).

CONCLUSION

LCBDE can also be carried out as a safe and effective approach to remove CBD stones in elderly patients, although they have higher risk of chronic diseases.
