An international survey: the role of specialist nurses in adult respiratory extracorporeal membrane oxygenation

An exploration of intensive care nurses' perceptions of workload in providing extracorporeal membrane oxygenation (ECMO) support: A descriptive qualitative study

BACKGROUND

There is increasing use of extracorporeal membrane oxygenation (ECMO) in intensive care, where nurses provide the majority of the required ongoing care of cannulas, circuit, and console. Limited evidence currently exists that details nursing perspectives, experiences, and challenges with workload in the provision of ECMO care.

OBJECTIVE

The objective of this study was to investigate intensive care nurses' perceptions of workload in providing specialist ECMO therapy and care in a high-volume ECMO centre.

METHODS

The study used a qualitative descriptive methodology through semistructured interviews. Data were analysed using an inductive thematic analysis approach following Braun and Clarke's iterative process. This study was conducted in an intensive care unit within an Australian public, quaternary, university-affiliated hospital, which provides specialist state-wide service for ECMO.

FINDINGS

Thirty ECMO-specialist trained intensive care nurses were interviewed. This study identified three key themes: (i) opportunity; (ii) knowledge and responsibilities; and (iii) systems and structures impacting on intensive care nurses' workload in providing ECMO supportive therapy.

CONCLUSIONS

Intensive care nurses require advanced clinical and critical thinking skills. Intensive care nurses are motivated and engaged to learn and acquire ECMO skills and competency as part of their ongoing professional development. Providing bedside ECMO management requires constant monitoring and surveillance from nurses to care for the one of the most critically unwell patient populations in the intensive care unit setting. As such, ECMO nursing services require a suitably trained and educated workforce of intensive care trained nurses. ECMO services provide clinical development opportunities for nurses, increase their scope of practice, and create advanced practice-specialist roles.

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.

Factors associated with 30-day in-hospital mortality in critically ill adult patients receiving extracorporeal membrane oxygenation: A retrospective cohort study

OBJECTIVE

To identify factors associated with the 30-day in-hospital mortality rate among adult patients requiring extracorporeal membrane oxygenation (ECMO) in intensive care units.

RESEARCH METHODOLOGY

Retrospective cohort study including 148 patients who underwent ECMO for at least 48 h between March 2010 and August 2021. The patients were divided into survivors and non-survivors based on their 30-day in-hospital survival. We obtained the sociodemographic information and pre- and post-ECMO data from electronic medical records. Kaplan-Meier survival curves and Multivariate Cox proportional hazards regression were used to analyse the data.

SETTING

A tertiary-care university hospital in South Korea.

MAIN OUTCOME MEASURES

The 30-day in-hospital mortality rate was the principal outcome measure.

RESULTS

The 30-day in-hospital mortality rate was 49.3% (n = 73). Kaplan-Meier analysis demonstrated that the duration of ECMO support in the 50th percentile of surviving patients was 13 days. Multivariable Cox regression analysis showed that new-onset renal failure, lower mean arterial pressure, and ECMO weaning failure were associated with an increased 30-day in-hospital mortality risk among patients who received ECMO. Subgroup analysis also revealed a significant association between weaning failure and 30-day in-hospital mortality after adjusting for covariates in patients undergoing veno-arterial ECMO.

CONCLUSION

Close monitoring of post-ECMO renal function and mean arterial pressure is required to minimize the risk of 30-day in-hospital mortality, especially in adults within the first two weeks of ECMO initiation. Moreover, the success of ECMO weaning should be optimized by collaboration within the ECMO team.

IMPLICATIONS FOR CLINICAL PRACTICE

Critical care nurses should pay close attention to patients' response to weaning trials as well as alternations in renal function and mean arterial pressure during ECMO support. Furthermore, developing nursing care guidelines for adult patients receiving ECMO and standardized training programs for nurses in intensive care, are required in Korea.

Developing a competency framework for extracorporeal membrane oxygenation nurses: A qualitative study

AIM

To develop a competency framework applicable to Chinese extracorporeal membrane oxygenation (ECMO) nurses.

DESIGN

A qualitative study was performed following the consolidated criteria for reporting qualitative research.

METHODS

Semi-structured interviews based on the critical incident technique were conducted among 21 ECMO care providers recruited from five well-known ECMO centres in Guangzhou, China. Interview transcripts were coded and analysed using the constant comparative method. The data collection period lasted from November 2021 to April 2022.

RESULTS

A competency framework for ECMO nurses was identified. It included four domains: knowledge, skills, behaviours and attitudes, containing 33 subcompetencies and 66 items.

RELEVANCE TO CLINICAL PRACTICE

This framework can be a reference for the assessment and training of ECMO nurses.

Nursing workforce, education, and training challenges to implementing extracorporeal membrane oxygenation services in Australian intensive care units: A qualitative substudy

BACKGROUND

The use of extracorporeal membrane oxygenation (ECMO) is increasing in the management of critical care patients. ECMO service delivery requires an organisation-supported approach to ensure appropriate resources to deliver training, equipment, capacity, staffing, and the required model of care for quality care delivery. The aim of this nested substudy was to explore challenges specific to nursing staff in ECMO services in Australian intensive care units.

METHODS

This was a nested substudy within a qualitative study using semistructured focus group discussions conducted with 83 health professionals, which included 40 nurses. There were 14 focus groups across 14 ECMO centres participating in the binational ECMO (EXCEL) registry of Australia and New Zealand. An inductive thematic analysis focused on the nurse's experiences of the barriers and facilitators for nursing in providing an ECMO service.

RESULTS

Four themes emerged relating to the nurse's experience of implementing ECMO services: workforce requirements, workload demands, models of care, and level of experience. The complexity and intensity of caring for ECMO patients may need to be considered an additional factor in the burnout in critical care nurses. Current nursing ratios and responsibilities in critical care need to be considered, with the opportunity for the development of specialist advanced practitioner nursing roles.

CONCLUSION

This study highlights the challenges for nursing in providing ECMO services in the intensive care setting. The complexity and intensity of ECMO is challenging and leads to concerns regarding burnout and workforce preparedness. New models of care need to be considered to mitigate the barriers for nursing identified across ECMO centres.

The lived experience by patients and family members of extracorporeal membrane oxygenation: A qualitative study

OBJECTIVE

To examine the lived experience of extracorporeal membrane oxygenation (ECMO) by patients and their families, and their relationship with intensive care clinicians.

RESEARCH METHODOLOGY

Semi-structured interviews were conducted with six patients who had received ECMO and with four of their family members. The data were analysed narratively using a constant comparative method.

SETTING

Patients were treated at a major acute care hospital in British Columbia between 2014 and 2021. ECMO was used either as a bridge to recovery or to organ transplant. Four had family members bedside throughout, while two had virtual visits due to COVID-19 infection control measures.

FINDINGS

ECMO was experienced through a triad of relationships between the patient, key family members and key clinicians. The strength, directionality and focus of these relationships shifted during therapy and realigned once ECMO was removed. The largest shift involved family members. Post-ECMO, patients relied almost entirely on spouses, adult children and clinical team members to reconstruct their experience. The connection between families and clinical team members was limited and changed little.

CONCLUSIONS

The lived experience of ECMO was complex in ways yet to be comprehensively reported in the literature. This technology had particular impact on family members when ECMO was used as a bridge to transplant and where run times extended to multiple weeks. COVID-19 infection control restrictions further complicated how this technology was experienced. Findings from this study highlight the importance of intensive care nurses recognising the critical role family members play as witnesses whose experiences later allow patients to make sense of their journey post-discharge.

Perception of other healthcare professionals about the nurses' role and competencies in veno-venous extracorporeal membrane oxygenation care: A qualitative study

Aim

This study aimed to explore the perception of other healthcare professionals, including the doctors, physiotherapists and perfusionists, about the nurses' role and competencies in veno‐venous extracorporeal membrane oxygenation.

Background

Extracorporeal membrane oxygenation is considered as a challenging clinical activity that requires critical decision and rapid response from nurses, particularly in emergencies. It was observed that nurses are primarily responsible for bedside management of these patients, and teamwork was found helping the nurses to manage this high‐acuity care. However, little is known on the perception of other healthcare professionals about the nurses' roles and competencies, which would contribute to further improvements in quality extracorporeal membrane oxygenation care.

Design

This was a qualitative descriptive study.

Methods

One‐to‐one in‐depth interviews were conducted with nine healthcare professionals working in extracorporeal membrane oxygenation care in an adult intensive care unit of a general hospital in Kuwait.

Results

Participants reported that nurses play critical and multiple roles and responsibilities in the insertion, maintenance, weaning, and retrieval of extracorporeal membrane oxygenation, plus providing general nursing care, and performed their roles competently. Heavy workload, less recognition and support, and individual differences in competence were reported as possible barriers to the nurses' performance.

Conclusion

Other healthcare professionals recognize continuous training, having experience, teamwork, and increased staffing as measures that can promote the nurses' role in extracorporeal membrane oxygenation.

ECMO During a Pandemic: A COVID-19 Quality Improvement Process

Extracorporeal membrane oxygenation is a modified form of cardiopulmonary bypass and a complex adult critical care therapy. No evidence appears to exist on sustaining relevant quality nursing standards during a pandemic. The aim for this quality improvement process was to address nursing provision in real time related to extracorporeal membrane oxygenation in a pandemic, providing fundamentals for future readiness. The Ishikawa fishbone diagram and a Plan-Do-Study-Act cycle were methods used. Process changes included implementation of a communication algorithm, an alternative nursing care model, increased nursing staffing and leadership visibility, use of perfusion services for nursing task support, and minimized nursing documentation. Changes applied were successful. We recommend increasing nursing staffing volume and support resources, applying a communication algorithm, and minimizing documentation requirements. These strategies are generalizable to other clinical nursing areas in similar pandemics or disasters.

Workforce and Task Sharing of Nurses in the Japanese Intensive Care Unit-Cross-Sectional Postal Survey

This study aimed to estimate the number of nurses who independently care for patients with severe respiratory failure receiving mechanical ventilation (MV) or veno-venous extracorporeal membrane oxygenation (VV-ECMO). Additionally, the study analyzed the actual role of nurses in the treatment of patients with MV and VV-ECMO. We performed a cross-sectional study using postal questionnaire surveys. The study included 725 Japanese intensive care units (ICUs). Data were analyzed using descriptive statistics. Among the 725 ICUs, we obtained 302 responses (41.7%) and analyzed 282 responses. The median number of nurses per bed was 3.25. The median proportion of nurses who independently cared for patients with MV was 60% (IQR: 42.3–77.3). The median proportion of nurses who independently cared for patients with VV-ECMO was 46.9 (35.7–63.3%) in the ICUs that had experience with VV-ECMO use. With regard to task-sharing, 33.8% of ICUs and nurses did not facilitate weaning from MV. Nurses always titrated sedative dosage in 44.5% of ICUs. Nurse staffing might be inadequate in all ICUs, especially for the management of patients with severe respiratory failure. The proportion of competent nurses to care for severe respiratory failure in ICUs should be considered when determining the workforce of nurses.

The Implementation and Outcomes of a Nurse-Run Extracorporeal Membrane Oxygenation Program, a Retrospective Single-Center Study

Supplemental Digital Content is available in the text.

Due to a shortage of perfusionists and increasing utilization of extracorporeal membrane oxygenation in the United States, many programs are training nurses as bedside extracorporeal membrane oxygenation specialists (i.e., nurse-run extracorporeal membrane oxygenation). Our objective was to evaluate if a nurse-run extracorporeal membrane oxygenation program has noninferior survival to discharge and complication rates compared with a perfusionist-run extracorporeal membrane oxygenation program. Additionally, to sought to describe increases in extracorporeal membrane oxygenation capacity and the potential for cost savings by implementing a nurse-run extracorporeal membrane oxygenation program.

Extracorporeal Membrane Oxygenation as a Bridge to Lung Transplant: Considerations for Critical Care Nursing Practice

TOPIC

Candidates waiting for lung transplant are sicker now than ever before. Extracorporeal membrane oxygenation has become useful as a bridge to lung transplant for these critically ill patients.

CLINICAL RELEVANCE

Critical care nurses must be prepared to care for the increasing number of lung transplant patients who require this advanced support method.

PURPOSE OF PAPER

To provide critical care nurses with the foundational knowledge essential for delivering quality care to this high-acuity transplant patient population.

CONTENT COVERED

This review describes the types of extracorporeal membrane oxygenation (venovenous and venoarterial), provides an overview of the indications and contraindications for extracorporeal membrane oxygenation, and discusses the role of clinical bedside nurses in the treatment of patients requiring extracorporeal membrane oxygenation as a bridge to lung transplant.

Outcome and Cost of Nurse-led versus Perfusionist-led Extracorporeal Membrane Oxygenation

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) is a resource-intense modality of care whose use has grown exponentially. We examined volume and utilization trends to identify the financial break-even point that might serve to dichotomize between nurse specialist-led and perfusionist-led ECMO programs.

METHODS

Data pertaining to patients who required ECMO support between 2018 and 2019 were reviewed. ECMO staffing costs were estimated based on national trends and modelled by annual utilization and case volume. A break-even point was derived from a comparison between nurse specialist-led and perfusionist-led models. For each scenario, direct medical costs were calculated based on utilization which was in turn defined by "low" (4 days), "average" (10 days), and "high" (30 days) duration of time spent on ECMO.

RESULTS

Within the time frame, there was a total of 107 ECMO cases with a mean ECMO duration of 11 days, within the study time frame. Overall, ECMO nursing personnel costs were less than those for perfusionists ($108,000 vs $175,000). Programmatic costs were higher in the perfusionist-led versus nurse specialist-led model when annual utilization was greater than 10 cases and ECMO duration was longer than a mean of 9.7 days. There was no difference in survival between the two models.

CONCLUSIONS

Use of a perfusionist-led ECMO model may be more cost-conscious in the context of low utilization, smaller case volume and shorter ECMO duration. However, once annual case volume exceeds 10 and mean ECMO duration exceeds 10 days, the nurse specialist-led model may be more cost-conscious.

Checklists Improve Team Performance During Simulated Extracorporeal Membrane Oxygenation Emergencies: A Randomized Trial

Supplemental Digital Content is available in the text.

Objectives:

Extracorporeal membrane oxygenation–related complications are potentially catastrophic if not addressed quickly. Because complications are rare, high-fidelity simulation is recommended as part of the training regimen for extracorporeal membrane oxygenation specialists. We hypothesized that the use of standardized checklists would improve team performance during simulated extracorporeal membrane oxygenation emergencies.

Design:

Randomized simulation-based trial.

Setting:

A quaternary-care academic hospital with a regional extracorporeal membrane oxygenation referral program.

Subjects:

Extracorporeal membrane oxygenation specialists and other healthcare providers.

Interventions:

We designed six read-do checklists for use during extracorporeal membrane oxygenation emergencies using a modified Delphi process. Teams of two to three providers were randomized to receive the checklists or not. All teams then completed four simulated extracorporeal membrane oxygenation emergencies.

Measurements and Main Results:

Simulation sessions were video-recorded, and the number of critical tasks performed and time-to-completion were compared between groups. A survey instrument was administered before and after simulations to assess participants’ attitudes toward the simulations and checklists. We recruited 36 subjects from a single institution, randomly assigned to 15 groups. The groups with checklists completed more critical tasks than participants in the control groups (90% vs 75%; p < 0.001). The groups with checklists performed a higher proportion of both nontechnical tasks (71% vs 44%; p < 0.001) and extracorporeal membrane oxygenation–specific technical tasks (94% vs 86%; p < 0.001). Both groups reported an increase in reported self-efficacy after the simulations (p = 0.003). After adjusting for multiple comparisons, none of the time-to-completion measures achieved statistical significance.

Conclusions:

The use of checklists resulted in better team performance during simulated extracorporeal membrane oxygenation emergencies. As extracorporeal membrane oxygenation use continues to expand, checklists may be an attractive low-cost intervention for centers looking to reduce errors and improve response to crisis situations.

COVID–19急性呼吸不全への人工呼吸管理とECMO管理：基本的考え方(Mechanical ventilation and extracorporeal membrane oxygenation for acute respiratory failure owing to COVID–19: basic concept)

The pillars of managing critically ill patients with acute respiratory failure owing to coronavirus disease 2019 (COVID–19) are mechanical ventilation and extracorporeal membrane lung oxygenation (ECMO) as supportive therapies for impaired respiratory function. Given the increasing number of patients with COVID–19, a summary of standardized care regarding ECMO that can serve as a reference in clinical practice is proposed as an expert consensus statement. Indications, management practices, and caveats for ECMO management are described, including those in the presence of resource constraints.

Development of the Adult ECMO Specialist Certification Examination

The American Society of Extracorporeal Technology Board of Directors, consistent with the American Society of Extracorporeal Technology's safe patient care improvement mission, charged the International Board of Blood Management to write a knowledge and skill certification examination for healthcare personnel employed as adult extracorporeal membrane oxygenation (ECMO) specialists. Nineteen nationally recognized ECMO subject-matter experts were selected to complete the examination development. A job analysis was performed, yielding a job description and examination plan focused on 16 job categories. Multiple-choice test items were created and validated. Qualified ECMO specialists were identified to complete a pilot examination and both pre- and post-examination surveys. The examination item difficulty and candidate performance were ranked and matched using Rasch methodology. Candidates' examination scores were compared with their profession, training, and experience as ECMO specialists. The 120-item pilot examination form ranked 76 ECMO specialist candidates consistent with their licensure, ECMO training, and clinical experience. Forty-three registered nurses, 28 registered respiratory therapists, four certified clinical perfusionists, and one physician assistant completed the pilot examination process. Rasch statistics revealed examination reliability coefficients of .83 for candidates and .88 for test items. Candidates ranked the appropriateness for examination items consistent with the item content, difficulty, and their personal examination score. The pilot examination pass rate was 80%. The completed examination product scheduled for enrollment in March 2020 includes 100 verified test items with an expected pass rate of 84% at a cut score of 67%. The online certification examination based on a verified job analysis provides an extramural assessment that ranks minimally prepared ECMO specialists' knowledge, skills, and abilities (KSA) consistent with safe ECMO patient care and circuit management. It is anticipated that ECMO facilities and ECMO service providers will incorporate the certification examination as part of their process improvement, safety, and quality assurance plans.

Nurses' perception of their role in extracorporeal membrane oxygenation care: A qualitative assessment

BACKGROUND

Recently, there has been interest in the education of nursing personnel to provide veno-venous extracorporeal membrane oxygenation in Kuwait. There is need to understand the experience of nurses who take on this new role.

AIM

We aimed to explore the perspectives of nurses about their role, with a special focus on their competencies and the challenges faced while caring for patients who require extracorporeal membrane oxygenation.

METHODS

We used a qualitative descriptive approach, using in-depth individual interviews. Nineteen nurses working with veno-venous an extracorporeal membrane oxygenation machine in an adult intensive care unit of a general hospital in Kuwait were included in the study. Interviews were audio-recorded, transcribed verbatim, and analysed thematically.

RESULTS

The role of nurses was found to be diverse and challenging and involved engaging in multiple responsibilities. Nurses worked with other health care providers in a team, which facilitated their performance. Nurses viewed themselves as competent to perform their role and attributed their competency mainly to the training received and the experience spent providing extracorporeal membrane oxygenation care. In executing their role, nurses reported encountering significant challenges, including heavy workload, inefficient communication among colleagues, and a lack of an organized/supportive system.

CONCLUSIONS

This study suggests that nurses play an integral role in the management of patients on extracorporeal membrane oxygenation. An understanding of their role and their competence, the challenges they face with in the care setting, and providing a supportive environment is essential for transformation in the practice of extracorporeal membrane oxygenation nursing.

Simulation training for crises during venoarterial extracorporeal membrane oxygenation

Extracorporeal membrane oxygenation (ECMO) education, in particular with regards to crisis management during the provision of venoarterial extracorporeal membrane oxygenation (VA ECMO), is challenging due to its intrinsic characteristics-a complex, high risk, low volume clinical activity which requires dynamic decision making, interdisciplinary teamwork and communication, and rapid response. Simulation training that focuses on crisis resource management and interprofessional communication is well-suited to address these training needs. Institutional commitment to provide both capital and human resources is instrumental to the success of ECMO training programs. Future multicenter studies with standardized training curricula are required to investigate the impact of ECMO simulation training on patient outcome.

Establishing an ECMO program in a developing country: challenges and lessons learned

Aim:

The ECMO (extracorporeal membrane oxygenation) Program at the American University of Beirut Medical Center was established in November 2015 as the first program serving adult and pediatric population in a low-resource setting. The aim of the study is to describe the challenges faced during the establishment of the program and factors leading to its success.

Methods:

The program establishment is described. The preparation phase, included the strategic, financial, and clinical planning by administration, nursing, and a multidisciplinary team of physicians. The training and education phase included all the involved nurses, perfusionists, and physicians. Concerns were heard from various stakeholders, and the challenges were analyzed and discussed.

Results:

The preparation committee chose the adequate equipment, responded to the concerns, defined roles and responsibilities through credentialing and privileging, wrote policies and protocols, and established a strategy to decide for the ECMO indication. Selected team of nurses, physicians, and perfusionists are identified and trained locally, and abroad. A full-time ECMO physician was recruited to launch the program. Twelve patients (6 adults, 3 children, and 3 neonates) were supported by ECMO, for cardiac and respiratory indications. Eleven patients were supported by veno-arterial ECMO, and 1 patient (a neonate) with veno-venous ECMO. Overall, 75% survived to decannulation and 41% survived to discharge.

Conclusion:

With limited human and financial resources, new ECMO centers need to carefully establish selection criteria that may differ from those used in developed countries. Indications should be discussed on a case by case basis, taking into account clinical, social, and financial issues. This experience might help other institutions in developing countries to build their own program despite financial and human limitations.
