Relatives' experiences of unsuccessful out-of-hospital cardiopulmonary resuscitation attempts: a qualitative analysis.

Aim: Relatives of patients who have experienced an out of hospital cardiac arrest (OHCA) experience confusion and distress during resuscitation. Clear information from ambulance clinicians and the opportunity to witness the resuscitation helps them navigate the chaotic scene. However, UK-based evidence concerning relatives' experiences of unsuccessful resuscitation attempts and interactions with ambulance clinicians is lacking. This qualitative study explores those experiences to inform ambulance clinician practice.

Methods: Two ambulance services in the UK identified OHCA events attended by their clinicians within the previous two weeks. After a minimum of three months relatives of non-survivors of these events were invited to participate in either a remote or face-to-face interview. Interviews focussed on their experiences of the resuscitation attempt and interactions with ambulance clinicians, their feelings at the time, and their reflections on the event afterwards. Data were analysed using reflexive thematic analysis.

Results: Semi-structured interviews were conducted with 14 relatives of OHCA non-survivors. Thematic analysis identified four themes. Cardiac arrest is a traumatic event for relatives, with chaotic noisy scenes increasing their distress. Many described feelings symptomatic of Post-Traumatic Stress Disorder since the event. During resuscitation, participants needed information from clinicians about what was happening, and provided information about their relatives' wishes. Participants needed reassurance from clinicians that everything possible was done to save their relative and were reassured when they could witness some of the resuscitation. Participants were surprised how long resuscitation seemed to last; some were distressed that it lasted so long.

Conclusion: Relatives' experiences highlight two key challenges for ambulance clinicians: (1) being aware of the tension relatives feel between needing reassurance that the crew is doing everything to save the patient and wanting to avoid prolonged and ultimately futile resuscitation attempts; and (2) having ongoing conversations with those present to inform clinical decision-making whilst managing the resuscitation attempt.
