Experiences of adult extracorporeal membrane oxygenation patients following discharge: A mixed methods study

Health-related quality of life assessment instruments for extracorporeal membrane oxygenation survivors: A scoping review

BACKGROUND AND OBJECTIVE

Extracorporeal membrane oxygenation (ECMO) has been successfully and widely used in adult patients for the past 5 years. About 50% of these patients can survive and are discharged from hospitals. Health-related quality of life (HRQOL) is crucial for evaluating survived ECMO patients. This scoping review aims to identify instruments commonly used to measure HRQOL of ECMO survivors and give pertinent instrument characteristics.

METHODS

A systematic search was conducted in PubMed, Web of Science, EMBASE (OVID), MEDLINE (OVID), CINAHL (EBSCO), Cochrane Library, and three Chinese databases from January 2012 to December 2021. Two reviewers independently reviewed publication selection and data extraction.

RESULTS

Twenty-nine studies met the inclusion criteria. Most studies (93%) were cross-sectional, and the median (or average) follow-up time ranged from 3 months to 9 years. Two prospective studies (7%) followed patients longitudinally until 1 year after discharge. ECMO survivors had poorer long-term HRQOL than the general population. However, it is comparable to or better than patients with other critical or chronic illnesses. Identified HRQOL assessment instruments show four generic HRQOL instruments, one disease-specific HRQOL instrument, and nineteen single-dimensional instruments. Seven instruments were used in more than three articles. SF-36 (86.2%), IES/IES-R (41.4%), and HADS (37.9%) were the most frequently used instruments.

CONCLUSION

The timing, frequency, and tools for HRQOL assessment of ECMO survivors are variable. No ECMO-specific HRQOL instrument was developed and validated. Further studies on assessment instruments are warranted. Research is also needed to identify interventions that may enhance HRQOL in ECMO survivors.

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.

Do-(Not-)Mechanical-Circulatory-Support Orders: Should We Ask All Cardiac Surgery Patients for Informed Consent for Post-Cardiotomy Extracorporeal Life Circulatory Support?

Post-cardiotomy extracorporeal life support (PC-ECLS) has seen a substantial increase in use over the past 10 years. PC-ECLS can be a life-saving procedure and is mostly applied in the presence of unexpected, severe cardio-respiratory complication. Despite PC-ECLS being critical in allowing for organ recovery, it is unfortunately closely connected with an unpredictable outcomes, high morbidity, and, even in the case of cardiac function improvement, potential sustained disabilities that have a life-changing impact for the patient and his or her family. Since the decision to start PC-ECLS is made in an acute setting, there is often only limited or no time for self-determined choices. Due to the major impact of the intervention, it would be highly desirable to obtain informed consent before starting PC-ECLS, since the autonomy of the patient and shared-decision making are two of the most important ethical values in modern medicine. Recent developments regarding awareness of the impacts of a prolonged intensive care stay make this a particularly relevant topic. Therefore, it would be desirable to develop a structural strategy that takes into account the likelihood of such an intervention and the wishes and preferences of the patient, and thus the related autonomy of the patient. This article proposes key points for such a strategy in the form of a PC-ECLS informed consent, a do-(not-)mechanical-circulatory-support order (D(N)MCS), and specific guidelines to determine the extent of the shared decision making. The concept presented in this article could be a starting point for improved and ethical PC-ECLS treatment and application.
