The impact of COVID-19 on emergency medical service-led out-of-hospital cardiac arrest resuscitation: a qualitative study.

Background: Following the emergence of COVID-19, there have been local and national changes in the way emergency medical service (EMS) staff respond to and treat patients in out-of-hospital cardiac arrest (OHCA). The views of EMS staff on the impact of COVID-19 and management of OHCA have not previously been explored. This study aimed to explore the views of staff, with a specific focus on communication during resuscitation, resuscitation procedures and the perception of risk.

Methods: A qualitative phenomenological enquiry was conducted. A purposive sample of n = 20 participants of various clinical grades was selected from NHS EMS providers in the United Kingdom. Data were collected using semi-structured interviews, transcribed verbatim and inductive thematic analysis was applied.

Results: Three main themes emerged which varied according to clinical grade, location and guidelines.Decision making: Staff generally felt supported to make best-interest termination of resuscitation decisions. Staff made informed decisions to compromise on recommended levels of personal protective equipment (PPE), since it felt impractical in the pre-hospital context, to improve communication or to reduce delays to care.Service pressures: Availability of operational staff and in-hospital capacity were reduced. Staff felt pressure and disconnect from the continuous updates to clinical guidelines which resulted in organisational change fatigue.Moral injury: The emotional impacts of prolonged and frequent exposure to failed resuscitation attempts and patient death caused many staff to take time away from work to recover.

Conclusion: This qualitative study is the first known to explore staff views on the impacts of COVID-19 on OHCA resuscitation, which found positive outcomes but also negative impacts important to inform EMS systems. Staff felt that COVID-19 created delays to the delivery of resuscitation, which were multi-faceted. Staff developed new ways of working to overcome the barriers of impractical PPE. There was little impact on resuscitation procedures. Moving forwards, EMS should consider how to limit organisational change and better support the ongoing emotional impacts on staff.
