Long-term outcome after endoscopic ligation of acute esophageal variceal bleeding in patients with liver cirrhosis

Endoscopic variceal ligation (EVL) has been the standard treatment for acute variceal bleeding (AVB). However, reports of long-term prognosis after EVL are scarce. Therefore, the current work aimed to investigate the long-term outcome and prognostic modifiers of cirrhotic cases presented with acute esophageal variceal bleeding and managed with EVL. The current prospective work comprised primarily 276 consecutive grown-up cirrhotic cases presenting with AVB and managed with EVL. Two-hundred patients who completed the study till death or 3-year follow-up were enrolled in final analysis. The primary outcome measure was occurrence of rebleeding and all-cause mortality. By the end of follow up 56 patients (28%) developed rebleeding and 78 (39%) died. The independent factors associated with rebleeding were lacking follow up EVL (OR: 4.8, 95%CI: 1.9-12.2), BMI > 30 kg/m2 (OR: 0.-, 95%CI: 0.2-0.9), Child class C (OR: 3.8, 95%CI: 1.8-7.8), and grade IV varices (OR: 2.6, 95%CI: 1.3-5.3). The independent factors associated with mortality were: Age > 65 years (OR: 32.4, 95%CI: 8.7-120.3), rebleeding (OR: 98.4, 95%CI: 27.9-347.0), coexistence of HCC (OR: 7.4, 95%CI: 2.0-27.4), and lacking follow up EVL (OR: 6.1, 95%CI: 1.2-31.1). Recurrent bleeding after emergency endoscopic ligation of acute esophageal variceal bleeding in cirrhotic cases is a rather common complication that significantly increases the mortality rate. The liver condition, lack of follow up endoscopy, old age, and severity of esophageal varices are independent prognostic indicator of rebleeding and morality.

Innovative Use of High-Fidelity Lung Simulators to Test a Ventilator Splitter Device

The coronavirus disease 2019 (COVID-19) pandemic has rapidly exposed health care system inadequacies. Hospital ventilator shortages in Italy compelled US physicians to consider creative solutions, such as using Y-pieces or T-pieces, to preclude the need to make decisions of life or death based on medical equipment availability. We add to current knowledge and testing capacity for ventilator splitters by reporting the ability to examine the functionality of ventilator splitters by using 2 high-fidelity lung simulators. Data obtained by the high-fidelity lung simulators included: tidal volume, respiratory rate, minute ventilation, peak inspiratory pressure, peak plateau pressure, and positive end-expiratory pressure.

Remodulin® Pump Failure: An Emergency Medicine Simulation Scenario

Pulmonary hypertension (PH) is a progressive disease that causes high patient mortality. With limited hemodynamic reserve, many PH patients require maintenance IV infusion medications to maintain their activities of daily living. One common delivery method for this targeted therapy is through a Remodulin® (treprostinil) pump. When presenting for emergent evaluation, decompensating PH patients have a broad differential diagnosis including pump failure. PH patients are at a high risk of poor patient outcomes given the difficulty in recognizing PH-specific symptoms and unique aspects of their management. Therefore, learners will benefit from participating in an immersive simulation-based PH patient scenario in a safe learning environment. Here, we present a simulated scenario of a decompensating PH patient on a Remodulin® pump.

Medical Decision-Making in the Physician Hierarchy: A Pilot Pedagogical Evaluation

PURPOSE

Recently, the American College of Graduate Medical Education included medical decision-making as a core competency in several specialties. To date, the ability to demonstrate and measure a pedagogical evolution of medical judgment in a medical education program has been limited. In this study, we aim to examine differences in medical decision-making of physician groups in distinctly different stages of their postgraduate career.

METHODS

The study recruited physicians with a wide spectrum of disciplines and levels of experience to take part in 4 medical simulations divided into 2 categories, abdominal pain (biliary colic [BC] and renal colic [RC]) or chest pain (cardiac ischemia with ST-segment elevation myocardial infarction [STEMI] and pneumothorax [PTX]). Evaluation of medical decision-making used the Medical Judgment Metric (MJM). The targeted selection criteria for the physician groups are administrative physicians (APs), representing those with the most experience but whose current duties are largely administrative; resident physicians (RPs), those enrolled in postgraduate medical or surgical training; and mastery level physicians (MPs), those deemed to have mastery level experience. The study measured participant demographics, physiological responses, medical judgment scores, and simulation time to case resolution. Outcome differences were analyzed using Fisher exact tests with post hoc Bonferroni-adjusted z tests and single-factor analysis of variance F tests with post hoc Tukey honestly significant difference, as appropriate. The significance threshold was set at P < .05. Effect sizes were determined and reported to inform future studies.

RESULTS

A total of n = 30 physicians were recruited for the study with n = 10 participants in each physician group. No significant differences were found in baseline demographics between groups. Analysis of simulations showed a significant (P = .002) interaction for total simulation time between groups RP: 6.2 minutes (±1.58); MP: 8.7 minutes (±2.46); and AP: 10.3 minutes (±2.78). The AP MJM scores, 12.3 (±2.66), for the RC simulation were significantly (P = .010) lower than the RP 14.7 (±1.15) and MP 14.7 (±1.15) MJM scores. Analysis of simulated patient outcomes showed that the AP group was significantly less likely to stabilize the participant in the RC simulation than MP and RP groups (P = .040). While not significant, all MJM scores for the AP group were lower in the BC, STEMI, and PTX simulations compared with the RP and MP groups.

CONCLUSIONS

Physicians in distinctly different stages of their respective postgraduate career differed in several domains when assessed through a consistent high-fidelity medical simulation program. Further studies are warranted to accurately assess pedagogical differences over the medical judgment lifespan of a physician.

Advanced closed-loop communication training: the blindfolded resuscitation

Closed-loop communication (CLC) improves task efficiency and decreases medical errors; however, limited literature on strategies to improve real-time use exist. The primary objective was whether blindfolding a resuscitation leader was effective to improve crisis resource management (CRM) skills, as measured by increased frequency of CLC. Secondary objectives included whether blindfolding affected overall CRM performance or perceived task load. Participants included emergency medicine (EM) or EM/paediatric dual resident physicians. Participants completed presurveys, were block randomised into intervention (blindfolded) or control groups, lead both adult and paediatric resuscitations and completed postsurveys before debriefing. Video recordings of the simulations were reviewed by simulation fellowship-trained EM physicians and rated using the Ottawa CRM Global Rating Scale (GRS). Frequency of CLC was assessed by one rater via video review. Summary statistics were performed. Intraclass correlation coefficient was calculated. Data were analysed using R program for analysis of variance and regression analysis. There were no significant differences between intervention and control groups in any Ottawa CRM GRS category. Postgraduate year (PGY) significantly impacts all Ottawa GRS categories. Frequency of CLC use significantly increased in the blindfolded group (31.7, 95% CI 29.34 to 34.1) vs the non-blindfolded group (24.6, 95% CI 21.5 to 27.7). Participant’s self-rated perceived NASA Task Load Index scores demonstrated no difference between intervention and control groups via a Wilcoxon rank sum test. Blindfolding the resuscitation leader significantly increases frequency of CLC. The blindfold code training exercise is an advanced technique that may increase the use of CLC.

Development of a Simulation Scenario Evaluation Tool (SSET): modified Delphi study

Introduction

One critical aspect of successful simulation facilitation is development of written scenarios. However, there are no validated assessment tools dedicated to the evaluation of written simulation scenarios available. Our aim was to develop a tool to evaluate the quality of written simulation demonstrating content validity.

Methods

A comprehensive literature search did not yield a validated assessment tool dedicated for the evaluation of written simulation scenarios. A subsequent search yielded six templates published for written simulation scenario design. From these templates, critical scenario elements were identified to create an evaluation instrument with six components of scenario quality with corresponding anchors and rating scale. Subsequently, a national group of simulation experts were engaged via survey methodology to rate the content of the proposed instrument. Ultimately, a modified two-round Delphi approach was implemented to demonstrate consensus of the final assessment tool.

Results

38 responses were obtained in round 1, while 22 complete responses were obtained in round 2. Round 1 kappa values ranged from 0.44 to 1.0, indicating moderate to almost perfect rater agreement for inclusion of the six proposed components. Kappa values specifically regarding scale and anchors ranged from 0 to 0.49. After revisions, there was a significant level of agreement (p<0.05) of all items of the proposed assessment tool in the second-round survey except for item 10. Of note, all initial respondents indicated that they had never evaluated written scenarios with an assessment tool.

Conclusions

The Simulation Scenario Evaluation Tool, developed using a national consensus of content experts, is an instrument demonstrating content validity that assesses the quality of written simulation scenarios. This tool provides a basis to guide structured feedback regarding the quality of written simulation scenarios.

Iatrogenic Critical Care Procedure Complication Boot Camp: A Simulation-based Pilot Study

BACKGROUND

Traditional medical education strategies teach learners how to correctly perform procedures while neglecting to provide formal training on iatrogenic error management. Error management training (EMT) requires active exploration as well as explicit encouragement for learners to make and learn from errors during training. Simulation provides an excellent methodology to execute a curriculum on iatrogenic procedural complication management. We hypothesize that a standardized simulation-based EMT curriculum will improve learner's confidence, cognitive knowledge, and performance in iatrogenic injury management.

METHODS

This was a pilot, prospective, observational study performed in a simulation center using a curriculum developed to educate resident physicians on iatrogenic procedural complication management. Pre- and postintervention assessments included confidence surveys, cognitive questionnaires, and critical action checklists for six simulated procedure complications. Assessment data were analyzed using medians and interquartile ranges (IQRs), and the paired change scores were tested for median equality to zero via Wilcoxon signed rank tests with p < 0.05 considered statistically significant.

RESULTS

Eighteen residents participated in the study curriculum. The median (IQR) confidence increased significantly by a summed score of 12.5 (8.75-17.25; p < 0.001). Similarly, the median (IQR) knowledge significantly increased by 6 (3-8) points from the pre- to postintervention assessment (p < 0.001). For each of the simulation cases, the number of critical actions performed increased significantly (p < 0.001 to p = 0.002).

CONCLUSION

We demonstrated significant improvement in the confidence, clinical knowledge, and performance of critical actions after the completion of this curriculum. This pilot study provides evidence that a structured EMT curriculum is an effective method to teach management of iatrogenic injuries.

Setup and Execution Of the Blindfolded Code Training Exercise

Miscommunication is the most common cause of preventable patient harm in medicine. Currently, there is limited knowledge of innovative techniques to improve resident physician communication and leadership strategies in high-acuity situations. The blindfolded code training exercise removes visual stimuli from the team leader, forcing the team leader to effectively utilize closed-loop communication. The simple act of blindfolding the team leader creates a learning environment where the leader must utilize a conceptual framework and critical thinking strategies to organize the team and manage the resuscitation. An advantage to this teaching technique is that it does not require any special simulation equipment, making it a low-cost approach. The blindfolded code training exercise can be applied to the management of any critically ill patient where the primary objective is to focus on developing communication skills in acute resuscitations. The purpose of the description of the blindfolded code training exercise is to provide guidance on how to perform this innovative teaching technique to force effective closed-loop communication.

Iatrogenic emergency medicine procedure complications and associated trouble-shooting strategies

PURPOSE

The purpose of this paper is to provide a consolidated reference for the acute management of selected iatrogenic procedural injuries occurring in the emergency department (ED).

DESIGN/METHODOLOGY/APPROACH

A literature search was performed utilizing PubMed, Scopus, Web of Science and Google Scholar for studies through March of 2017 investigating search terms "iatrogenic procedure complications," "error management" and "procedure complications," in addition to the search terms reflecting case reports involving the eight below listed procedure complications.

FINDINGS

This may be particularly helpful to academic faculty who supervise physicians in training who present a higher risk to cause such injuries.

ORIGINALITY/VALUE

Emergent procedures performed in the ED present a higher risk for iatrogenic injury than in more controlled settings. Many physicians are taught error-avoidance rather than how to handle errors when learning procedures. There is currently very limited literature on the error management of iatrogenic procedure complications in the ED.

Advanced Practice Provider Critical Care Boot Camp: A Simulation-Based Curriculum

The demand for advanced practice providers (APPs) is increasing across the United States to meet necessary provider staffing requirements including in intensive care settings. Currently, participation in formal postgraduate training programs, or residencies, for APPs is not required for clinical practice, such that most of the APPs immediately enter into the workforce following completion of their initial graduate-level training. Consequently, this results in a supervised training period until APPs develop the necessary competencies to practice more autonomously. Educational programs that support specialty competency development may facilitate the transition of APPs into clinical practice, allowing them to be credentialed to perform essential procedures as quickly as possible. The goal of this boot camp was to provide training for APPs in common critical care, high-risk procedures, and to provide leadership development for high-risk cases to expedite their orientation process. The following manuscript describes our experience with the development, implementation, and short-term evaluation of this training program.

Evaluation of Technical Competency in Healthcare Simulation (E-TeCHS) tool: a modified Delphi study

Background

Graduates of simulation fellowship programmes are expected to have the ability to perform a variety of simulation specific skills at the time of graduation. Currently, simulation fellowship directors have access to tools to assess the ability of a fellow to debrief learners. However, there is no tool to assess a simulation fellow’s competency in technical skills. The purpose of our manuscript was to develop and obtain content validation of a novel instrument designed to assess a simulation fellow’s ability to perform the five core simulation technical skills.

Methods

The study protocol was based on a methodology for content validation of curriculum consensus guidelines. This approach involves a three-step process, which includes the initial delineation of the curricular content. This was then followed by the validation of the curricular content using survey methodology and lastly obtaining consensus on modifications using Delphi methodology.

Results

Two rounds of modified Delphi methodology were performed. Seventy-four respondents provided feedback on the round 1 survey and 45 respondents provided feedback on round 2. The final assessment tool has five elements and 16 subitems with four optional subitems.

Conclusion

The Evaluation of Technical Competency in Healthcare Simulation tool provides an instrument developed from a national consensus of content experts. This tool provides simulation fellowship directors a method to evaluate fellows’ competency in technical skills.

Telepresent Focused Assessment With Sonography for Trauma Examination Training Versus Traditional Training for Medical Students: A Simulation-Based Pilot Study

OBJECTIVES

Telepresent education is becoming an important modality in medical education, as it provides a means for instructors to lead education sessions via videoconferencing technologies. This study aimed to compare the effectiveness of telepresent ultrasound training versus traditional in-person ultrasound training.

METHODS

Medical student cohorts were educated by either traditional in-person instruction or telementoring on how to perform a focused assessment with sonography for trauma (FAST) examination. Effectiveness was evaluated by pre- and post-multiple-choice tests (knowledge), confidence surveys, and summative simulation scenarios (hands-on FAST simulation). Formative simulation scenario debriefings were evaluated by each student using the Debriefing Assessment for Simulation in Healthcare student version (DASH-SV).

RESULTS

Each method of instruction had significant increases in knowledge, confidence, and hands-on FAST simulation performance (P < .05). The collective increase in knowledge was greater for the in-person group, whereas the improvement in FAST examination performance during simulations was greater for the telementored group. Confidence gains were comparable between the groups. The DASH-SV scores were significantly higher for the in-person group for each criterion; however, both methods were deemed effective via median scoring.

CONCLUSIONS

Telepresent education is a viable option for teaching the FAST examination to medical students.

Evaluation of simulation debriefing methods with interprofessional learning

Interprofessional education (IPE) using simulations provides a rich environment for mastery learning and deliberate practice. The debriefing phase is identified as the most valuable by learners, yet investigation into the most effective format for debriefing interprofessional (IP) groups has largely gone unexplored. To determine the best practices in IP simulation debriefing, we compared perceived effectiveness of in-person versus teledebriefing, and single versus IP co-debriefer models according to 404 Debriefing Assessment for Simulation in Healthcare Student-Version (DASH-SV) scores from students in medicine, nursing, and respiratory therapy (n = 135) following three critical care simulations. All calculated total mean scores were in the acceptable range (above 4.0), indicating a positive experience for all methods. We found statistically significantly higher scores for in-person (M = 5.79) compared to teledebriefing (M = 4.96, p < .001). Single debriefer (M = 6.09) compared to IP co-debriefer DASH scores (M = 5.93) for all scenarios were not significantly different (p = .059). Our results suggest that teledebriefing may provide a solution for simulation programs with off-site or rural learners, and that a single in-person debriefing can be equally effective as co-debriefing for IP students.

Mechanical Ventilation Boot Camp Curriculum

Medical management of mechanically ventilated patients is challenging to novice providers. Incorrect management of this population may lead to increased morbidity and mortality. A three-day simulation-based boot camp serves to provide one-on-one instruction with a critical care provider. These intensivists may dispense personalized immediate feedback as learners engage in hands-on practice with a real mechanical ventilator. Multiple different pathologies can be reviewed that may not be encountered in the clinical setting. Learners can visualize immediate consequences of their actions and may troubleshoot and ask questions, all while in a safe learning environment. We describe the use of human-patient simulators connected to breathing simulators and mechanical ventilators. Potential curriculum executors should be aware of the cost of the equipment and the time needed to dedicate to boot camp execution; however, this intensive interactive training has been shown to increase provider competency, knowledge, and confidence in ventilator management. This curriculum outline provides guidance on how to execute a simulation-based boot camp to train providers on the management of mechanically ventilated patients.

Telepresent mechanical ventilation training versus traditional instruction: a simulation-based pilot study

Background

Mechanical ventilation is a complex topic that requires an in-depth understanding of the cardiopulmonary system, its associated pathophysiology and comprehensive knowledge of equipment capabilities.

Introduction

The use of telepresent faculty to train providers in the use of mechanical ventilation using medical simulation as a teaching methodology is not well established. The aim of this study was to compare the efficacy of telepresent faculty versus traditional in-person instruction to teach mechanical ventilation to medical students.

Materials and methods

Medical students for this small cohort pilot study were instructed using either in-person instruction or telementoring. Initiation and management of mechanical ventilation were reviewed. Effectiveness was evaluated by pre- and post-multiple choice tests, confidence surveys and summative simulation scenarios. Students evaluated faculty debriefing using the Debriefing Assessment for Simulation in Healthcare Student Version (DASH-SV).

Results

A 3-day pilot curriculum demonstrated significant improvement in the confidence (in person P<0.001; telementoring P=0.001), knowledge (in person P<0.001; telementoring P=0.022) and performance (in person P<0.001; telementoring P<0.002) of medical students in their ability to manage a critically ill patient on mechanical ventilation. Participants favoured the in-person curriculum over telepresent education, however, resultant mean DASH-SV scores rated both approaches as consistently to extremely effective.

Discussion

While in-person learners demonstrated larger confidence and knowledge gains than telementored learners, improvement was seen in both cases. Learners rated both methods to be effective. Technological issues may have contributed to students providing a more favourable rating of the in-person curriculum.

Conclusions

Telementoring is a viable option to provide medical education to medical students on the fundamentals of ventilator management at institutions that may not have content experts readily available.

Medical judgement analogue studies with applications to spaceflight crew medical officer

Background

The National Aeronautics and Space Administration (NASA) developed plans for potential emergency conditions from the Exploration Medical Conditions List. In an effort to mitigate conditions on the Exploration Medical Conditions List, NASA implemented a crew medical officer (CMO) designation for eligible astronauts. This pilot study aims to add knowledge that could be used in the Integrated Medical Model.

Methods

An analogue population was recruited for two categories: administrative physicians (AP) representing the physician CMOs and technical professionals (TP) representing the non-physician CMOs. Participants completed four medical simulations focused on abdominal pain: cholecystitis (CH) and renal colic (RC) and chest pain: cardiac ischaemia (STEMI; ST-segment elevation myocardial infarction) and pneumothorax (PX). The Medical Judgment Metric (MJM) was used to evaluate medical decision making.

Results

There were no significant differences between the AP and TP groups in age, gender, race, ethnicity, education and baseline heart rate. Significant differences were noted in MJM average rater scores in AP versus TP in CH: 13.0 (±2.25), 4.5 (±0.48), p=<0.001; RC: 12.3 (±2.66), 4.8 (±0.94); STEMI: 12.1 (±3.33), 4.9 (±0.56); and PX: 13.5 (±2.53), 5.3 (±1.01), respectively.

Discussion

There could be a positive effect on crew health risk by having a physician CMO. The MJM demonstrated the ability to quantify medical judgement between the two analogue groups of spaceflight CMOs. Future studies should incorporate the MJM in a larger analogue population study to assess the medical risk for spaceflight crewmembers.

Pediatric Trauma Boot Camp: A Simulation Curriculum and Pilot Study

Trauma is a leading cause of morbidity and mortality in infants and children worldwide. Trauma education is one of the most commonly reported deficiencies in pediatric emergency medicine (PEM) training. In this study, we describe the creation of a pediatric trauma boot camp in which trainees' basic knowledge, level of confidence, teamwork, and communication skills are assessed. The primary goal of this pilot study was to create a simulation-based pediatric trauma curriculum for PEM fellows and emergency medicine residents utilizing Kern's curricular conceptual framework. This was a pilot, prospective, single cohort, exploratory, observational study utilizing survey methodology and a convenience sample. The curriculum consisted of a two-day experience that included confidence surveys, a cognitive multiple-choice questionnaire, and formative and summative simulation scenarios. At the conclusion of this intensive simulation-based trauma boot camp participants reported increased confidence and demonstrated significant improvement in the basic knowledge and performance of the management of pediatric trauma cases in a simulated environment.

Development, Validation, and Implementation of a Medical Judgment Metric

Background: Medical decision making is a critical, yet understudied, aspect of medical education. Aims: To develop the Medical Judgment Metric (MJM), a numerical rubric to quantify good decisions in practice in simulated environments; and to obtain initial preliminary evidence of reliability and validity of the tool. Methods: The individual MJM items, domains, and sections of the MJM were built based on existing standardized frameworks. Content validity was determined by a convenient sample of eight experts. The MJM instrument was pilot tested in four medical simulations with a team of three medical raters assessing 40 participants with four levels of medical experience and skill. Results: Raters were highly consistent in their MJM scores in each scenario (intraclass correlation coefficient 0.965 to 0.987) as well as their evaluation of the expected patient outcome (Fleiss’s Kappa 0.791 to 0.906). For each simulation scenario, average rater cut-scores significantly predicted expected loss of life or stabilization (Cohen’s Kappa 0.851 to 0.880). Discussion: The MJM demonstrated preliminary evidence of reliability and validity.

Training the trainers: a survey of simulation fellowship graduates

BACKGROUND

Coupled with the expansion of simulation has been the development and growth of medical simulation fellowships. These non-accredited fellowships do not have a standardized curriculum and there are currently no studies investigating the simulation fellowship experience. The purpose of this study was to explore the simulation fellowship experience of graduates throughout North America and how it prepared them for their post-fellowship career.

METHODS

A web-based survey was developed by Emergency Medicine attending physicians both of whom completed one-year fellowships in medical simulation. Prior to distribution, the survey was reviewed and tested by three simulation fellowship graduates and a PhD researcher. Feedback was integrated into the survey prior to distribution. The survey consisted of a maximum of 29 multiple choice questions including two step-logic questions and two open response questions. The survey was distributed to simulation fellowship directors in multiple disciplines and the directors were asked to forward the survey to graduates. Additionally, the Society for Academic Emergency Medicine Simulation Academy list-serve was utilized for distribution of the survey.

RESULTS

The survey had 35 responses. The majority of respondents completed fellowship within the last two years (66%, 23/35). Fellowship graduates strongly agreed or agreed that their fellowship adequately prepared them for their post-fellowship simulation career (88%). Graduates report that research design/reporting (53%) and administration (18%) were areas of their fellowship curriculum that needed the most improvement.

CONCLUSION

The majority of simulation fellowship graduates agreed that their fellowship experience adequately prepared them for their post-fellowship simulation career. Graduates also felt that training in research and administration are areas that could be improved.
