Sudden cardiac death: the perspectives of Spanish survivors

The experiences of cardiac arrest survivors and their key supporters following cardiac arrest: A systematic review and meta-ethnography

AIM

To review qualitative studies on the experience of sudden cardiac arrest survival from the perspective of both survivors and their key supporters, including family/close friends.

METHODS

A seven-step meta-ethnography and synthesis of qualitative evidence was undertaken, informed by the Meta-Ethnography Reporting Guidelines (eMERGe). Four major databases were searched (Medline, EMBASE, CINAHL, PsycINFO; January 1995-January 2022, updated July 2023) for qualitative studies exploring survivors' and/or key supporters' experiences of cardiac arrest survival. The Critical Appraisal Skills Programme checklist and Grading of Recommendations Assessment, Development and Evaluation - Confidence in Evidence from Reviews of Qualitative Research (GRADE-CERQual) were applied to evaluate the overall confidence in research findings. Constructs were identified from each paper, informing theme and sub-theme development.

RESULTS

From 15,917 unique titles/abstracts and 196 full-text articles, 32 met the inclusion criteria. Three themes captured the survivors' experiences: 1) Making sense of my cardiac arrest; 2) Learning to trust my body and mind; and 3) Re-evaluating my life. A further three themes reflected key supporters' experiences: 1) Emotional turmoil; 2) Becoming a carer: same person but different me; and 3) Engaging with a new and unknown world. However, limited data and some methodological weaknesses in included studies reduced confidence in several themes. The findings were conceived within the overarching concept of 'negotiating a new normal'.

CONCLUSIONS

The enduring psychosocial and physical sequelae of cardiac arrest survival substantially impacts the lives of survivors and their key supporters, requiring negotiation of their 'new normality'. The need for sense-making, physical and psychological recovery, and the new roles for key supporters should be strong considerations in the development of future interventions.

What Are the Care Needs of Families Experiencing Sudden Cardiac Arrest? A Survivor- and Family-Performed Systematic Review, Qualitative Meta-Synthesis, and Clinical Practice Recommendations

INTRODUCTION

Cardiac arrest care systems are being designed and implemented to address patients', family members', and survivors' care needs. We conducted a systematic review and a meta-synthesis to understand family experiences and care needs during cardiac arrest care to create treatment recommendations.

METHODS

We searched eight electronic databases to identify articles. Study findings were extracted, coded and synthesized. Confidence in the quality, coherence, relevance, and adequacy of data underpinning the resulting findings was assessed using GRADE-CERQual methods.

RESULTS

In total 4181 studies were screened, and 39 met our inclusion criteria; these studies enrolled 215 survivors and 418 family participants-which includes both co-survivors and bereaved family members. From these studies findings and participant data we identified 5 major analytical themes: (1) When the crisis begins we must respond; (2) Anguish from uncertainty, we need to understand; (3) Partnering in care, we have much to offer; (4) The crisis surrounding the victim, ignore us, the family, no longer; (5) Our family's emergency is not over, now is when we need help the most. Confidence in the evidence statements are provided along with our review findings.

DISCUSSION

The family experience of cardiac arrest care is often chaotic, distressing, complex and the aftereffects are long-lasting. Patient and family experiences could be improved for many people. High certainty family care needs identified in this review include rapid recognition and response, improved information sharing, more effective communication, supported presence and participation, or supported absence, and psychological aftercare.

The prevalence of anxiety and depression in cardiac arrest survivors: A systematic review and meta-analysis

OBJECTIVE

This systematic review aimed to identify the prevalence of anxiety and depression in cardiac arrest (CA) survivors.

METHODS

A systematic review and network meta-analysis was performed on observational studies in adult cardiac arrest survivors with psychiatric disorders from PubMed, Embase, Cochrane Library and Web of Science. In the meta-analysis, we combined the prevalence quantitatively and analyzed the subgroup based on the classification indexes.

RESULTS

We identified 32 articles that met the inclusion criteria. Regarding anxiety,the pooled prevalence was 24% (95% CI, 17-31%) and 22% (95% CI, 13-26%) in short-term and long-term respectively. The subgroup analysis showed that the pooled incidence in in-hospital cardiac arrest (IHCA) and out-of-hospital cardiac arrests (OHCA) survivors was 14.0% (95%CI, 9.0-20.0%) and 28.0% (95%CI, 20.0-36.0%) for short-term anxiety.The incidence of anxiety measured by, Hamilton Anxiety Rating Scale(HAM-A) and State-Trait Anxiety Inventory(STAI) was higher than other tools(P < 0.01). Regarding depression,the data analysis showed that the pooled incidence of short-term and long-term depression was 19% (95% CI, 13-26%) and 19% (95% CI, 16-25%), respectively. The subgroup analysis showed that the incidence of short-term and long-term depression was 8% (95% CI, 1-19%) and 30% (95% CI, 5-64%) for IHCA survivors, and was 18% (95% CI, 11-26%) and 17% (95% CI, 11-25%) for OHCA survivors. The incidence of depression measured by Hamilton Depression Rating Scale(HDRS) and Symptom check list-90(SCL-90) was higher than other assessment tools(P < 0.01).

CONCLUSIONS

The meta-analysis indicated a high prevalence of anxiety and depression in CA survivors, and those symptoms persisted 1 year or more after CA. Evaluation tool is an important factor affecting the measurement results.

Feeling understood for the first time: experiences of participation in rehabilitation after out-of-hospital sudden cardiac arrest

AIMS

Survivors of out-of-hospital sudden cardiac arrest (SCA) may suffer from long-term cognitive, psychological, or physical post-arrest consequences impacting and disrupting daily life. To adjust to and manage daily life is critical, and therefore a tailored rehabiliation programme was introduced to the participants. The study aimed to explore the lived experience among cardiac arrest survivors.

METHODS AND RESULTS

Data were gathered through six focus group interviews during a cardiac arrest rehabilitation programme. Thirty-three out-of-hospital SCA survivors (8 women and 25 men) participated. Time since cardiac arrest was on average 12-57 months. An exploratory qualitative design inspired by Ricoeur's phenomenological hermeneutics was applied. Two main themes emerged from the analysis and interpretation: (i) a lack of support from the health system in the transition from hospital to daily life; and (ii) feeling understood for the first time. The findings revealed that out-of-hospital SCA survivors experience a knowledge gap struggling for support. Attending the programme, gaining knowledge and experiencing peer support was described as a revelation for them.

CONCLUSION

The findings suggest that out-of-hospital SCA survivors felt understood for the first time when attending a cardiac arrest rehabilitation programme. A post-arrest pathway is needed led by a coordinating cardiac arrest specialist nursing service together with allied healthcare professionals. Focus on hypoxic brain injuries, emotional burdens, and supportive strategies are essential in the transition to daily life. Facilitated peer support is warranted.

Sudden Cardiac Arrest Survivorship: A Scientific Statement From the American Heart Association

Cardiac arrest systems of care are successfully coordinating community, emergency medical services, and hospital efforts to improve the process of care for patients who have had a cardiac arrest. As a result, the number of people surviving sudden cardiac arrest is increasing. However, physical, cognitive, and emotional effects of surviving cardiac arrest may linger for months or years. Systematic recommendations stop short of addressing partnerships needed to care for patients and caregivers after medical stabilization. This document expands the cardiac arrest resuscitation system of care to include patients, caregivers, and rehabilitative healthcare partnerships, which are central to cardiac arrest survivorship.

A Meta-ethnography of Out-of-Hospital Cardiac Arrest Survivors' Meanings on Life and Death

BACKGROUND

Although out-of-hospital cardiac arrest (OHCA) survivors' physiological outcomes have been addressed, less is known on the holistic needs of individuals after OHCA, which hinders our ability to prioritize care around what really matters to survivors.

AIM

The aim of this study was to interpretatively synthesize qualitative findings on OHCA survivors' perceptions and meanings of life and death and existential issues.

METHODS

We used a meta-ethnographic synthesis of published qualitative studies addressing the experiences of OHCA survivors based on a systematic literature search (CINAHL, PsycINFO, Scopus, PubMed). Studies were selected based on predefined inclusion/exclusion criteria. The identified studies were subjected to a quality appraisal based on the Critical Appraisal Skills Programme.

RESULTS

Based on eligibility criteria, 6 phenomenological studies were included, of overall medium to high quality. One core theme, "the reality of death," and 4 main themes were identified: "redefining existence"; "revaluing death"; "being familiar with, yet oblivious of death"; and "living consciously." Emerging from the realization of death, the themes appeared to describe a gradual progression toward living consciously.

CONCLUSIONS

An existential trajectory and a need for meaning are central in the experience of OHCA survivors. When existential issues are not addressed, the ongoing suffering may interfere with survivors' recovery and quality of life. Future research needs to address specific needs and ways to support survivors' meaning-making.

Long-term survivors of cardiac arrest: A narrative inquiry

Background:

Despite extensive knowledge and research in cardiac health there is limited understanding in how a cardiac arrest influences the life of long-term survivors.

Objective:

The aim of this study was to explore how long-term survivors of a cardiac arrest adjusted to their new reality, expressed in their re-storied narratives.

Methods:

Seven individuals surviving a cardiac arrest 5–26 years ago were interviewed through in-depth conversations over a six-month period. These interviews were analysed using Clandinin and Connelly’s framework of narrative inquiry.

Results:

Seven threads were found: Disbelief, Surveillance of their body, Loss of control and desire for normality, Keeping fit and informing others, Gratefulness, Spirituality – luck and fate, and Fragility of life and dying.

Conclusions:

All seven long-term survivors of cardiac arrest expressed a positive attitude. Despite the nature of the cardiac arrest and the hurdles that followed, they have a heightened appreciation for life. This indicates that after the adaptation to their new reality of being a cardiac arrest survivor life returns to a new normality.

Revealed by degrees: Patients' experience of receiving information after in-hospital cardiac arrest

AIMS AND OBJECTIVES

To describe patients' experience of receiving information about the event after having a cardiac arrest in hospital.

BACKGROUND

In Sweden, approximately 2,600 people per year experience cardiac arrest in hospital. After a cardiac arrest, the patient is entitled to receive information about what has occurred. This information must be provided in a way that does not do the patient more harm than good. In order to provide information to patients in a satisfactory manner for them, knowledge about how patients react to information in this situation is valuable.

DESIGN

We used a qualitative approach with interviews and content analysis.

METHODS

Twenty patients participated in face-to-face interviews analysed by content analysis. Consolidated criteria for reporting qualitative studies were used.

RESULTS

The analysis resulted in three categories: Getting the information gradually, Understanding information received and Seeking clarity. The subcategories that emerged were as follows: Indirect information, Short and direct information, Explanatory information, Lack of information, Unsatisfactory information, Hard-to-understand information, Insight, Unanswered questions, Hard-to-formulate questions, Requesting information and Searching independently for knowledge.

CONCLUSIONS

The patients needed gradual and repeated information during their hospitalisation, and repeated information was continually required after their discharge from hospital. Whether or how the information was given varied. The patients' experience was that they sometimes lacked opportunities for conversation and asking questions, while they also found it hard to formulate questions. Patients who have a cardiac arrest in hospital appear to have similar information needs to patients whose cardiac arrest takes place outside the hospital context.

RELEVANCE TO CLINICAL PRACTICE

Information on the patient's cardiac arrest should be given in gradual stages, according to the patient's needs. The information needs to be repeated during the hospital stay and after discharge. Healthcare professional should gain insight into patients' responses and create information that is adapted to the individual.

A systematic review and meta-synthesis of the qualitative literature exploring the experiences and quality of life of survivors of a cardiac arrest

BACKGROUND

Survival following cardiac arrest and subsequent cardiopulmonary resuscitation (CPR) is increasing worldwide, mainly due to greater awareness of the symptoms of cardiac events and an increased attention to CPR training. Although patient outcomes remain unpredictable and quantitative studies suggest that the overall quality of life (QOL) is acceptable, it is valuable to synthesise qualitative studies exploring these phenomena in depth, providing a deeper knowledge of survivors' experiences and QOL.

AIMS

To critically appraise and synthesise the qualitative literature on survivors' experiences of a cardiac arrest and CPR with the aim of identifying common themes that can inform clinical pathways and thereby improve survivor outcomes and QOL.

METHODS

A systematic review and meta-synthesis of the qualitative literature, using Thomas and Harden's framework, and confined to peer-reviewed papers published from 2000 to 2015, which were identified through database searches of EBSCO, OVID and ProQuest.

RESULTS

The search produced 204 papers, and of these, seven relevant papers were identified for review. Data extraction included setting, participants, research design, data collection, analysis and themes. Five qualitative themes were identified and were the subject of this meta-synthesis: multitude of contrasting feelings; disruption in the continuum of time; new reality and psychological challenges; changed body with new limitations; and confrontation with death.

CONCLUSION

This review provides insights into the experiences of survivors' QOL after CPR. Increased knowledge can improve person-centred care in the immediate and forthcoming care after the event, both in terms of planning for discharge and in the future care of people who survive a cardiac arrest.
