Development and Evaluation of An Abbreviated Extracorporeal Membrane Oxygenation (ECMO) Course for Nonsurgical Physicians and Nurses

Efficacy of a Single Day Extracorporeal Membrane Oxygenation Training Course for Critical Care Air Transport Team Eligible Personnel

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) is an advanced medical technology that is used to treat respiratory and heart failure. The U.S. military has used ECMO in the care of combat casualties during Operation Enduring Freedom and Operation Iraqi Freedom as well as in the treatment of patients during the recent Coronavirus Disease 2019 pandemic. However, few Military Health System personnel have training and experience in the use of ECMO therapy. To address this dearth of expertise, we developed and evaluated an accelerated ECMO course for military medical personnel.

OBJECTIVES

To compare the efficacy of an accelerated ECMO course for Military Health System critical care teams.

METHODS

Seventeen teams, each consisting of a physician and nurse, underwent a 5-h accelerated ECMO course. Similar to our previous live-tissue ECMO training program (phases I and II), each team watched prerecorded ECMO training lectures. Subjects then practiced priming the ECMO circuit, cannulating ECMO, initiating ECMO, and correcting common complications on an ECMO simulation model. An added component to this phase III project included transportation and telemedicine consultation availability. Training success was evaluated via knowledge and confidence assessments, and observation of each team attempting to initiate ECMO on a Yorkshire swine patient model, transport the patient model, and troubleshoot complications with the support of telemedicine consultation when desired.

RESULTS

Seventeen teams successfully completed the course. All seventeen teams (100%) successfully placed the swine on veno-arterial ECMO. Of those, 15 teams successfully transitioned to veno-arterial-venous ECMO. The knowledge assessments of physicians and nurses increased by 12.2% from pretest (mean of 62.1%, SD 10.4%) to posttest (mean of 74.4%, SD 8.2%), P < .0001; their confidence assessments increased by 41.1% from pretest (mean of 20.1%, SD 11.8%) to posttest (mean of 61.2%, SD 18.6%).

CONCLUSIONS

An abbreviated 1-day lecture and hands-on task-trainer-based ECMO course resulted in a high rate of successful skill demonstration and improvement of physicians' and nurses' knowledge assessments and confidence levels, similar to our previous live-tissue training program. When compared to our previous studies, the addition of telemedicine and patient transportation to this study did not affect the duration or performance of procedures.

ICU Nurses' Perception of Sensitive Indicators of Quality of Care for ECMO Patients in Guizhou Province, China: A Cross-Sectional Study

Purpose

This study aimed to investigate the cognitive evaluation level of ICU nurses in Guizhou Province, China, on the sensitivity indicators of nursing quality for ECMO patients.

Patients and Methods

This was a cross-sectional observational study conducted in Guizhou Province, China, from May to July 2023, 259 ICU nurses were surveyed. Objective sampling method was used to select the participants from 10 hospitals in Guizhou Province that carried out ECMO. Data were collected through questionnaire survey. Two researchers checked and recorded Epidata 3.1. SPSS 25.0 was used for statistical analysis of the data, and frequency, mean and component ratio were used for descriptive statistical analysis. The importance rating was used to reflect the degree of nurses' agreement with the indicators.

Results

The results of this study showed that 79.1% of the 253 ICU nurses in Guizhou Province, China, had not participated in training and courses related to indicators of quality of care evaluation for ECMO patients. The main way for ICU nurses to acquire knowledge related to indicators of quality of care sensitivity for ECMO patients was departmental training, which accounted for 87.4%. And the other ways, in descending order, were public, the matic lectures or academic conferences, journals and magazines; their evaluation scores of the importance of most of the quality of care sensitivity indicators for ECMO patients was moderate, with the scores ranging from 73 to 150. Among them, the range of importance evaluation scores for each indicator was 4.01 ~ 4.48.

Conclusion

The overall cognitive evaluation of ICU nurses in Guizhou Province, China, on most sensitivity indicators of quality of care for ECMO patients was moderate, and there is a general lack of systematic courses and training on the knowledge related to ECMO care quality sensitive indicators.

Efficacy of a single-day task trainer-based extracorporeal membrane oxygenation training course

Background

Extracorporeal membrane oxygenation (ECMO) is an advanced medical technology used to treat respiratory and heart failure. The coronavirus pandemic has resulted in significantly more ECMO patients worldwide. However, the number of hospitals with ECMO capabilities and ECMO-trained staff are limited. Training of personnel in ECMO could supplement this demand.

Objective

To evaluate our previously developed ECMO course using a task trainer-based training, as opposed to an existing live tissue-training model, and determine if such a program was adequate and could be expanded to other facilities.

Methods

Seventeen teams, each consisting of a physician and nurse, underwent a 5 hour accelerated ECMO course in which they watched prerecorded ECMO training lectures, primed circuit, cannulated, initiated ECMO, and corrected common complications. Training success was evaluated via knowledge and confidence assessments and observation of each team attempting to initiate ECMO while troubleshooting complications on a Yorkshire swine.

Results

Seventeen teams successfully completed the course. Sixteen teams (94%, 95% CI = 71%-100%) successfully placed the swine on veno-arterial ECMO. Of those 16 teams, 15 successfully transitioned to veno-arterial-venous ECMO. The knowledge assessments and confidence levels of physicians and nurses increased by 24.3% from pretest (mean of 65.3%, SD 14.4%) to posttest (mean of 89.6%, SD 10.3%), p < 0.0001.

Conclusions

An abbreviated one day lecture and hands-on task trainer-based ECMO course resulted in a high rate of successful skill demonstration and improvement of physicians' and nurses' knowledge assessments and confidence levels, similar to our previous live tissue training program.

A Scoping Review and Appraisal of Extracorporeal Membrane Oxygenation Education Literature

Background

Despite a recent rise in publications describing extracorporeal membrane oxygenation (ECMO) education, the scope and quality of ECMO educational research and curricular assessments have not previously been evaluated.

Objective

The purposes of this study are 1) to categorize published ECMO educational scholarship according to Bloom's educational domains, learner groups, and content delivery methods; 2) to assess ECMO educational scholarship quality; and 3) to identify areas of focus for future curricular development and educational research.

Methods

A multidisciplinary research team conducted a scoping review of ECMO literature published between January 2009 and October 2021 using established frameworks. The Medical Education Research Study Quality Instrument (MERSQI) was applied to assess quality.

Results

A total of 1,028 references were retrieved; 36 were selected for review. ECMO education studies frequently targeted the cognitive domain (78%), with 17% of studies targeting the psychomotor domain alone and 33% of studies targeting combinations of the cognitive, psychomotor, and affective domains. Thirty-three studies qualified for MERSQI scoring, with a median score of 11 (interquartile range, 4; possible range, 5-18). Simulation-based training was used in 97%, with 50% of studies targeting physicians and one other discipline.

Conclusion

ECMO education frequently incorporates simulation and spans all domains of Bloom's taxonomy. Overall, MERSQI scores for ECMO education studies are similar to those for other simulation-based medical education studies. However, developing assessment tools with multisource validity evidence and conducting multienvironment studies would strengthen future work. The creation of a collaborative ECMO educational network would increase standardization and reproducibility in ECMO training, ultimately improving patient outcomes.

Development of a Standardized Assessment of Simulation-based Extracorporeal Membrane Oxygenation Educational Courses

Background

In 2020, the Extracorporeal Life Support Organization education task force identified seven extracorporeal membrane oxygenation (ECMO) educational domains that would benefit from international collaborative efforts. These included research efforts to delineate the impact and outcomes of ECMO courses.

Objective

Development of a standardized online assessment tool to evaluate the effectiveness of didactic and simulation-based ECMO courses on participants’ confidence, knowledge, and simulation-based skills; participant satisfaction; and course educational benefits.

Methods

We performed a prospective multicenter observational study of five different U.S. academic institution–based adult ECMO courses that met Extracorporeal Life Support Organization endorsement requirements for course structure, educational content, and objectives. Standardized online forms were developed and administered before and after courses, assessing demographics, self-assessment regarding ECMO management, and knowledge examination (15 simple-recall multiple-choice questions). Psychomotor skill assessment was performed during the course (time to complete prespecified critical actions during simulation scenarios). Self-assessment evaluated cognitive, behavioral, and technical aspects of ECMO; course satisfaction; and educational benefits.

Results

Out of 211 participants, 107 completed both pre- and postcourse self-assessment forms (97 completed both pre- and postcourse knowledge forms). Fifty-three percent of respondents were physician intensivists, with most (51%) practicing at academic hospitals and with less than 1 year of ECMO experience (50%). After the course, participants reported significant increases in confidence across all domains (cognitive, technical, and behavioral, P < 0.0001, 95% confidence interval [CI], 1.2–1.5; P < 0.0001, 95% CI, 2.2–2.6; and P = 0.002, 95% CI, 1.7–2.1, respectively) with an increase in knowledge scores (P < 0.001; 95% CI, 1.4–2.5). These findings were most significant in participants with less ECMO experience. There were also significant reductions in times to critical actions in three of the four scored simulation scenarios. The results demonstrated participants’ satisfaction with most course aspects, with more than 95% expressing that courses met their educational goals.

Conclusion

We developed and tested a structured ECMO course assessment tool, demonstrating participants’ self-reported benefit as well as improvement in psychomotor skill acquisition, course satisfaction, and educational benefits. Course evaluation is feasible and potentially provides important information to improve ECMO courses. Future steps could include national implementation, addition of questions targeting clinical decision making to further assess knowledge gain, and multilanguage translation for implementation in international courses.
