ABSTRACT

Background: Just-in-time training (JITT) occurs in the clinical context when learners need immediate guidance for procedures due to a lack of proficiency or the need for knowledge refreshment. The master adaptive learner (MAL) framework presents a comprehensive model of transforming learners into adaptive experts, proficient not only in their current tasks but also in the ongoing development of lifelong skills. With the evolving landscape of procedural competence in emergency medicine (EM), trainees must develop the capacity to acquire and master new techniques consistently. This concept paper will discuss using JITT to support the development of MALs in the emergency department. Methods: In May 2023, an expert panel from the Society for Academic Emergency Medicine (SAEM) Medical Educator's Boot Camp delivered a comprehensive half-day preconference session entitled "Be the Best Teacher" at the society's annual meeting. A subgroup within this panel focused on applying the MAL framework to JITT. This subgroup collaboratively developed a practical guide that underwent iterative review and refinement. Results: The MAL-JITT framework integrates the learner's past experiences with the educator's proficiency, allowing the educational experience to address the unique requirements of each case. We outline a structured five-step process for applying JITT, utilizing the lumbar puncture procedure as an example of integrating the MAL stages of planning, learning, assessing, and adjusting. This innovative approach facilitates prompt procedural competence and cultivates a positive learning environment that fosters acquiring adaptable learning skills with enduring benefits throughout the learner's career trajectory. Conclusions: JITT for procedures holds the potential to cultivate a dynamic learning environment conducive to nurturing the development of MALs in EM.

ABSTRACT

A 33-yr-old female Western lowland gorilla (Gorilla gorilla gorilla) was diagnosed with a congenital umbilical hernia that was reducible and asymptomatic; change in the hernia was noted after parturition and concerns regarding increased risk of bowel incarceration developed. The hernia was successfully repaired with robot-assisted laparoscopic surgery. A 5-mon-old male Western lowland gorilla presented with bilateral inguinal hernias that were repaired via elective laparoscopic repair. In both cases, the gorillas did well without complications and never appeared to acknowledge wounds or exhibit signs of pain postoperatively. A literature review and interinstitutional survey was conducted to determine success rate of minimally invasive versus open repair of hernias in nonhuman primates (NHP). Of the cases identified, recurrence and/or wound morbidity was seen in 0% of laparoscopic repairs and 50% of open repairs. NHP may benefit from elective, minimally invasive surgical techniques that may reduce hernia recurrences and wound morbidity.

ABSTRACT

Background: Didactics play a key role in medical education. There is no standardized didactic evaluation tool to assess quality and provide feedback to instructors. Cognitive load theory provides a framework for lecture evaluations. We sought to develop an evaluation tool, rooted in cognitive load theory, to assess quality of didactic lectures. Methods: We used a modified Delphi method to achieve expert consensus for items in a lecture evaluation tool. Nine emergency medicine educators with expertise in cognitive load participated in three modified Delphi rounds. In the first two rounds, experts rated the importance of including each item in the evaluation rubric on a 1 to 9 Likert scale with 1 labeled as "not at all important" and 9 labeled as "extremely important." In the third round, experts were asked to make a binary choice of whether the item should be included in the final evaluation tool. In each round, the experts were invited to provide written comments, edits, and suggested additional items. Modifications were made between rounds based on item scores and expert feedback. We calculated descriptive statistics for item scores. Results: We completed three Delphi rounds, each with 100% response rate. After Round 1, we removed one item, made major changes to two items, made minor wording changes to nine items, and modified the scale of one item. Following Round 2, we eliminated three items, made major wording changes to one item, and made minor wording changes to one item. After the third round, we made minor wording changes to two items. We also reordered and categorized items for ease of use. The final evaluation tool consisted of nine items. Conclusions: We developed a lecture assessment tool rooted in cognitive load theory specific to medical education. This tool can be applied to assess quality of instruction and provide important feedback to speakers.

ABSTRACT

OBJECTIVES: The aim of this study was to determine if the quick Sepsis-Related Organ Failure Assessment (qSOFA) score assessed at and 48 hours after admission is prognostic for alcohol-induced acute pancreatitis (AAP) severity. METHODS: This is a retrospective cohort review study of 161 patients admitted to a single academic hospital in Houston, TX, with the diagnosis of AAP. Receiver operator characteristics analysis and logistic regression were used to assess the diagnostic accuracy and prognostic ability of the qSOFA score. RESULTS: A qSOFA score of 2 or higher at and 48 hours after admission had a specificity of 94% or greater and sensitivity of 33% or higher for pancreatitis severity and need for intensive care admission, intubation, or vasopressors. The qSOFA score at and 48 hours after admission was prognostic of intensive care unit admission by an adjusted odds ratio of 48.5 (95% confidence interval [CI], 6.4-1013.3; P < 0.001) and 18.8 (95% CI, 2.2-467.3; P < 0.05), respectively. The qSOFA score at admission was prognostic of severe pancreatitis by an adjusted odds ratio of 35.3 (95% CI, 7.2-224.3; P < 0.001). CONCLUSIONS: A qSOFA score of 2 or higher is highly specific and prognostic of multiple clinical outcomes both at and 48 hours after admission in patients with AAP.

ABSTRACT

BACKGROUND: COVID necessitated the shift to virtual resident instruction. The challenge of learning via virtual modalities has the potential to increase cognitive load. It is important for educators to reduce cognitive load to optimize learning, yet there are few available tools to measure cognitive load. The objective of this study is to identify and provide validity evidence following Messicks' framework for an instrument to evaluate cognitive load in virtual emergency medicine didactic sessions. METHODS: This study followed Messicks' framework for validity including content, response process, internal structure, and relationship to other variables. Content validity evidence included: (1) engagement of reference librarian and literature review of existing instruments; (2) engagement of experts in cognitive load, and relevant stakeholders to review the literature and choose an instrument appropriate to measure cognitive load in EM didactic presentations. Response process validity was gathered using the format and anchors of instruments with previous validity evidence and piloting amongst the author group. A lecture was provided by one faculty to four residency programs via ZoomTM. Afterwards, residents completed the cognitive load instrument. Descriptive statistics were collected; Cronbach's alpha assessed internal consistency of the instrument; and correlation for relationship to other variables (quality of lecture). RESULTS: The 10-item Leppink Cognitive Load instrument was selected with attention to content and response process validity evidence. Internal structure of the instrument was good (Cronbach's alpha = 0.80). Subscales performed well-intrinsic load (α = 0.96, excellent), extrinsic load (α = 0.89, good), and germane load (α = 0.97, excellent). Five of the items were correlated with overall quality of lecture (p < 0.05). CONCLUSIONS: The 10-item Cognitive Load instrument demonstrated good validity evidence to measure cognitive load and the subdomains of intrinsic, extraneous, and germane load. This instrument can be used to provide feedback to presenters to improve the cognitive load of their presentations.

ABSTRACT

Introduction: Code status discussions are poorly understood by patients and variably performed by admitting providers, yet they are used as a quality metric. Surgical specialties, such as Vascular Surgery, admit patients with urgent and life-threatening illness. Surgical trainees are less likely to receive communication skills interventions when compared with nonsurgical specialties. Without a documented code status, nurses and physicians lack guidance on patient preference in the case of cardiopulmonary arrest and may deliver unwanted measures, which may also result in poor outcomes. Methods: We conducted a before-after Plan-Do-Study-Act quality improvement project between May 2018 and May 2019. A needs assessment included baseline code status documentation rates for the Vascular Surgery department admissions. A communication skills training (CST) and documentation intervention was provided to all Vascular Surgery trainees and advance practice providers (APPs). Departmental e-mails were sent over the 12-month intervention period, which demonstrated the code status documentation rates and served as reminders to document code status. Results: A total of 29 vascular surgery trainees and APPs received the intervention. At completion of the intervention, learners reported increased comfort initiating a code status discussion, making a recommendation for cardiopulmonary resuscitation (CPR) status, and having a strategy to discuss code status. A total of 2762 patient admissions were reviewed, with 1562 patient admissions occurring during the 12-month intervention period. The average code status documentation rate for the three months before the intervention was 7.8%. At the end of the 12-month intervention, documentation rates were 44.9% and 6 months after completion of the study period, average rates remained 45.2%. There was no change in admission rates during the study period. Discussion: CST and regular reminders increased vascular surgery residents' and APPs' comfort in engaging in code status discussions. After intervention, documentation of code status discussions increased with persistence up to six months after the intervention.

ABSTRACT

Prognostic markers are needed to understand the disease course and severity in patients with Covid-19. There is evidence that Covid-19 causes gastrointestinal symptoms and abnormalities in liver enzymes. We aimed to determine if hepatobiliary laboratory data could predict disease severity in patients with Covid-19. In this retrospective, single institution, cohort study that analyzed patients admitted to a community academic hospital with the diagnosis of Covid-19, we found that elevations of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) and Alkaline Phosphatase (AP) at any time during hospital admission increased the odds of ICU admission by 5.12 (95% CI: 1.55-16.89; p = 0.007), 4.71 (95% CI: 1.51-14.69; p = 0.01) and 4.12 (95% CI: 1.21-14.06, p = 0.02), respectively. Hypoalbuminemia found at the time of admission to the hospital was associated with increased mortality (p = 0.02), hypotension (p = 0.03), and need for vasopressors (p = 0.02), intubation (p = 0.01) and hemodialysis (p = 0.002). Additionally, there was evidence of liver injury: AST was significantly elevated above baseline in patients admitted to the ICU (54.2 ± 15.70 U/L) relative to those who were not (9.2 ± 4.89 U/L; p = 0.01). Taken together, this study found that hypoalbuminemia and abnormalities in hepatobiliary laboratory data may be prognostic factors for disease severity in patients admitted to the hospital with Covid-19.

ABSTRACT

OBJECTIVE: Immediate-access arteriovenous grafts (IAAVGs), or early cannulation arteriovenous grafts (AVGs), are more expensive than standard grafts (sAVGs) but can be used immediately after placement, reducing the need for a tunneled dialysis catheter (TDC). We hypothesized that a decrease in TDC-related complications would make IAAVGs a cost-effective alternative to sAVGs. METHODS: We constructed a Markov state-transition model in which patients initially received either an IAAVG or an sAVG and a TDC until graft usability; patients were followed through multiple subsequent access procedures for a 60-month time horizon. The model simulated mortality and typical graft- and TDC-related complications, with parameter estimates including probabilities, costs, and utilities derived from previous literature. A key parameter was median time to TDC removal after graft placement, which was studied under both real-world (7 days for IAAVG and 70 days for sAVG) and ideal (no TDC placed with IAAVG and 1 month for sAVG) conditions. Costs were based on current Medicare reimbursement rates and reflect a payer perspective. Both microsimulation (10,000 trials) and probabilistic sensitivity analysis (10,000 samples) were performed. The willingness-to-pay threshold was set at $100,000 per quality-adjusted life-year (QALY). RESULTS: IAAVG placement is a dominant strategy under both real-world ($1201.16 less expensive and 0.03 QALY more effective) and ideal ($1457.97 less expensive and 0.03 QALY more effective) conditions. Under real-world parameters, the result was most sensitive to the time to TDC removal; IAAVGs are cost-effective if a TDC is maintained for ≥23 days after sAVG placement. The mean catheter time was lower with IAAVG (3.9 vs 8.7 months; P < .0001), as was the mean number of access-related infections (0.55 vs 0.74; P < .0001). Median survival in the model was 29 months. Overall mortality was similar between groups (76.3% vs 76.7% at 5 years; P = .33), but access-related mortality trended toward improvement with IAAVG (6.1% vs 6.8% at 5 years; P = .052). CONCLUSIONS: The Markov decision analysis model supported our hypothesis that IAAVGs come with added initial cost but are ultimately cost-saving and more effective. This apparent benefit is due to our prediction that a decreased number of catheter days per patient would lead to a decreased number of access-related infections.

ABSTRACT

BACKGROUND: Successful trauma resuscitation relies on multi-disciplinary collaboration. In most academic programs, general surgery (GS) and emergency medicine (EM) residents rarely train together before functioning as a team. METHODS: In our Multi-Disciplinary Trauma Evaluation and Management Simulation (MD-TEAMS), EM and GS residents completed manikin-based trauma scenarios and were evaluated on resuscitation and communication skills. Residents were surveyed on confidence surrounding training objectives. RESULTS: Residents showed improved confidence running trauma scenarios in multi-disciplinary teams. Residents received lower communication scores from same-discipline vs cross-discipline faculty. EM residents scored higher in evaluation and planning domains; GS residents scored higher in action processes; groups scored equally in team management. Strong correlation existed between team leader communication and resuscitative skill completion. CONCLUSION: MD-TEAMS demonstrated correlation between communication and resuscitation checklist item completion and communication differences by resident specialty. In the future, we plan to evaluate training-related resident behavior changes and specialty-specific communication differences by residents.

ABSTRACT

OBJECTIVES: The aim of this study was to determine if hypophosphatemia is more common in patients with severe alcohol-induced acute pancreatitis (AAP). METHODS: This is a retrospective, single institution, cohort study that analyzed 147 patients admitted to the hospital for AAP. Multivariate logistic regression was used to determine if hypophosphatemia would be related to clinical outcomes of disease severity. RESULTS: Hypophosphatemia was more common in patients with severe AAP at admission; in addition, all patients with severe AAP (100%) eventually developed hypophosphatemia during admission, relative to those with mild (43%) and moderately severe (54%) AAP. The magnitude of the lowest phosphate measurement obtained during admission was lower in patients with severe AAP (mean, 1.5 mg/dL, standard deviation [SD], 0.5 mg/dL) relative to those with mild (mean, 2.6 mg/dL; SD, 0.9 mg/dL) and moderately severe (mean, 2.3 mg/dL; SD, 0.9 mg/dL) AAP (P < 0.001). Finally, patients who developed hypophosphatemia during admission were more likely to require intensive care unit admission (P < 0.001), vasopressors (P = 0.01), or intubation (P = 0.003). CONCLUSIONS: Hypophosphatemia is more common and of greater magnitude in patients admitted to the hospital with severe AAP. In addition, patients with severe AAP who develop hypophosphatemia during admission are more likely to have poorer clinical outcomes.

ABSTRACT

D-dimer is a prognostic marker for Covid-19 disease mortality and severity in hospitalized patients; however, little is known about the association between D-dimer and other clinical outcomes. The aim of this paper was to define a threshold of D-dimer to use in hospitalized patients with Covid-19 and to assess its utility in prognosticating in-hospital mortality, development of an acute kidney injury (AKI), and need for hemodialysis, vasopressors, or intubation. This is a single-center, retrospective, cohort review study of 100 predominantly minority patients (94%) hospitalized with Covid-19. The electronic medical record system was used to collect data. Receiver operating characteristics (ROC) and area under the curve (AUC) analysis were used to determine optimal thresholds of peak D-dimer, defined as the highest D-dimer obtained during admission that was clinically meaningful. Odds ratios were then used to assess the relationship between peak D-dimer thresholds and clinical outcomes. D-dimer > 2.1 µg/mL and > 2.48 µg/mL had > 90% sensitivity and > 50% specificity for predicting need for vasopressors (AUC 0.80) or intubation (AUC 0.83) and in-hospital mortality (AUC 0.89), respectively. Additionally, D-dimer > 4.86 µg/mL had a 100% sensitivity and 81% specificity for predicting the need for hemodialysis (AUC 0.92). Furthermore, peak D-dimer > 2.48 µg/mL was associated with in-hospital mortality (p < 0.001), development of an AKI (p = 0.002), and need for intubation (p < 0.001), hemodialysis (p < 0.001), and vasopressors (p < 0.001). Peak D-dimer > 2.48 µg/mL may be a useful threshold that is prognostic of multiple clinical outcomes in hospitalized patients with Covid-19.

ABSTRACT

Covid-19 is a systemic viral respiratory illness that can cause gastrointestinal manifestations. There is evidence that Covid-19 can infect liver tissue and may cause transaminemia. A prognostic model is needed to aid clinicians in determining disease severity. The Model for End-Stage Liver Disease-Sodium (MELD-Na) score is a mortality assessment tool in liver transplant patients that has been found to be prognostic in other clinical situations. This study aimed to determine if the MELD-Na score was associated with disease severity in patients with Covid-19, as assessed by multiple clinical outcomes including death within 30 days of discharge and development of an acute kidney injury (AKI). This is a retrospective cohort study that analyzed patients admitted to a community academic hospital with the diagnosis of Covid-19. The 30-day MELD-Na score was found to be significantly higher in those who died (14.38 ± 6.92) relative to those who survived (9.68 ± 5.69; p = 0.03). Additionally, patients with a MELD-Na score greater than 10 were found to have higher risk of developing an AKI (odds ratio (OR) 3.31 (1.08, 10.17); p = 0.03), need for hemodialysis (OR 9.69 (1.74, 53.96); p = 0.007), require vasopressors (OR 4.55 (1.22, 16.99); p = 0.02), and have a longer hospital stay (OR 4.17 (1.05, 16.47); p = 0.03). The MELD-Na score may serve as a useful clinical scoring system for prognosis in patients admitted to the hospital with Covid-19.

ABSTRACT

This is a proof-of-concept study for the development of a field-deployable and low-cost PCR thermocycler (FLC-PCR) to perform Polymerase Chain Reaction (PCR) for the rapid detection of environmental E. coli. Four efficient (77.1 W) peltier modules are used as the central temperature control unit. One 250 W silicone heating pad is used for the heating lid. The PID (proportional-integral-derivative) control algorithm for the thermocycles is implemented by a low-cost 8-bit, 16 MHz microcontroller (ATMEGA328P-PU). ybbW and uidA genes from specific E. coli colonies were used as amplicons for the PCR reactions that were carried out by a commercial PCR machine (Bio-Rad) and our FLC-PCR thermocycler. The heating and cooling speeds averaged 1.11 ± 0.33°C/s which is on a par with the commercial bench-top PCR thermocycler and the efficiency of the heating lid outperformed the Bio-Rad PCR thermocycler. The overall cost of the system is lower than $200 which is more than ten times lower than commercially available units. The heating block can be customized to accommodate different PCR tubes and even microfluidic chambers. An 8000 W portable power generator will be used as the power supply for field studies.

ABSTRACT

OBJECTIVE: Arteriovenous graft (AVG) failures are typically associated with venous anastomotic (VA) stenosis. Current evidence regarding AVG thrombosis management compares surgical with purely endovascular techniques; few studies have investigated the "hybrid" intervention that combines surgical balloon thrombectomy and endovascular angioplasty and/or stenting to address VA obstruction. This study aimed to describe outcomes after hybrid intervention compared with open revision (patch venoplasty or jump bypass) of the VA in thrombosed AVGs. METHODS: Retrospective cohort study. Consecutive patients with a thrombosed AVG who underwent thrombectomy between January 2014 and July 2018 were divided into open and hybrid groups based on VA intervention; patients who underwent purely endovascular thrombectomy were excluded. Patient demographics, previous access history, central vein patency, AVG anatomy, type of intervention, and follow up data were recorded. Kaplan-Meier curves were used to analyse time from thrombectomy to first re-intervention (primary patency) and time to abandonment (secondary patency). Cox regression analysis was performed to evaluate predictors of failure. RESULTS: This study included 97 patients (54 females) with 39 forearm, 47 upper arm, and 11 lower extremity AVGs. There were 34 open revisions (25 patches, nine jump bypasses) and 63 hybrid interventions, which included balloon angioplasty ± adjunctive procedures (15 stents, five cutting balloons). Technique selection was based on physician preference. Primary patency for the open and hybrid groups was 27.8% and 34.2%, respectively, at six months and 17.5% and 12.9%, respectively, at 12 months (p = .71). Secondary patency was 45.1% and 38.5% for open and hybrid treatment, respectively, at 12 months (p = .87). An existing VA stent was predictive of graft abandonment (hazard ratio 4.4, 95% confidence interval 1.2-16.0; p = .024). Open vs. hybrid intervention was not predictive of failure or abandonment. CONCLUSION: Hybrid interventions for thrombosed AVGs are not associated with worse patency at six and 12 months compared with open revision.

ABSTRACT

INTRODUCTION: Prognostic factors are needed to aid clinicians in managing Covid-19, a respiratory illness. Lymphocytopenia has emerged as a simply obtained laboratory value that may correlate with prognosis. METHODS: In this article, we perform a retrospective cohort review study on patients admitted to one academic hospital for Covid-19 illness. We analyzed basic demographic, clinical, and laboratory data to understand the relationship between lymphocytopenia at the time of hospital admission and clinical outcomes. RESULTS: We discovered that lymphocyte count is lower (P = .01) and lymphocytopenia more frequent by an odds ratio of 3.40 (95% CI: 1.06-10.96; P = .04) in patients admitted to the Intensive Care Unit (ICU), a marker of disease severity, relative to those who were not. We additionally find that patients with lymphocytopenia were more likely to develop an acute kidney injury (AKI), a marker of organ failure, during admission by an odds ratio of 4.29 (95% CI: 1.35-13.57; P = .01). CONCLUSION: This evidence supports the hypothesis that lymphocytopenia can be an early, useful, and easily obtained, prognostic factor in determining the clinical course and disease severity of a patient admitted to the hospital for Covid-19.

ABSTRACT

Lectures are a common instructional method in medical education. Understanding the cognitive processes and theories involved in learning is essential for lecturers to be effective. Cognitive load theory is one theory that is becoming increasingly recognized in medical education and addresses the appropriate use of one's working memory. Memory is essential to knowledge acquisition. Two types of memory can be considered, working memory (processing of information) and long-term memory (storage of information). Working memory has a limited capacity. Cognitive load refers to the amount of information processing activity imposed on working memory and can be divided into three domains: intrinsic, extraneous, and germane. By attending to cognitive load, educators can promote learning. This paper highlights various ways of improving cognitive load for learners during lecture-based instruction by minimizing extraneous load, optimizing intrinsic load, and promoting germane load.

ABSTRACT

The COVID-19 pandemic has required a substantial change to the approach used for traditional, in-person continuing professional development (CPD) conferences. Running a virtual CPD conference will necessitate consideration of digital platforms and conversion of large group and small group sessions, abstract presentations, and networking events to a digital medium. This paper will discuss these challenges and present strategies to address them for CPD conference planning in the era of COVID-19.
