Extreme events (e.g. floods and disease outbreaks) can overwhelm healthcare workers (HCWs) and healthcare systems. During the COVID-19 pandemic, high levels of distress and mental ill health were reported by HCWs.

To examine and synthesise research findings reported in the qualitative literature regarding the stressors, and their psychosocial impacts, faced by HCWs in the UK during the COVID-19 pandemic, and to provide lessons for future support.

Qualitative articles were identified in EMBASE and OVID (preregistered on PROSPERO: CRD42022304235). Studies were required to have been published between January 2021 and January 2022 and to have examined the impact of COVID-19 on UK HCWs. We included 27 articles that represented the experiences of 2640 HCWs, assessed their quality using National Institute for Health and Care Excellence criteria and integrated their findings using thematic synthesis.

Several secondary stressors were identified, including lack of personal protective equipment, ineffective leadership and communication, high workloads and problems stemming from uncertainty and a lack of knowledge. Stressors were related to adverse psychosocial outcomes including worry, fatigue, lack of confidence in oneself and senior managers, impacts on teamwork and feeling unappreciated or that one’s needs are not recognised.

Our thematic synthesis moves beyond simply mapping stressors faced by HCWs by considering their antecedents, origins and psychosocial impacts. Utilising a theoretical framework that points towards systemic deficiencies, we argue that secondary stressors can be modified to remove their negative effects. Consequently, workforce planning should shift from focusing on individual change towards amending psychosocial environments in which HCWs work.

Terrorist incidents lead to a range of mental health outcomes for people affected, sometimes extending years after the event. Secondary stressors can exacerbate them, and social support can provide mitigation and aid recovery. There is a need to better understand distress and mitigating factors among survivors of the Manchester Arena attack in 2017.

We explored three questions. First, what experiences of distress did participants report? Second, how might secondary stressors have influenced participants’ psychosocial recoveries? Third, what part has social support played in the relationships between distress and participants’ recovery trajectories?

We conducted a cross-sectional online survey of a convenience sample of survivors of the Manchester Arena bombing (N = 84) in January 2021 (3 years 8 months post-incident), and a longitudinal study of the same participants’ scores on mental health measures over 3 years from September 2017.

Survivors’ mental well-being scores in early 2021 were significantly lower than general population norms. Longitudinal follow-up provided evidence of enduring distress. Secondary stressors, specifically disruptions to close relationships, were associated with greater post-event distress and slower recovery. We found an indirect relationship between identifying with, and receiving support from, others present at the event and mental well-being >3 years later.

The Arena attack has had an enduring impact on mental health, even in survivors who had a mild response to the event. The quality of close relationships is pivotal to long-term outcome. Constructive support from family and friends, and people with shared experiences, are key to social cure processes that facilitate coping and recovery.

Distress after major incidents is widespread among survivors. The great majority do not meet the criteria for mental health disorders and rely on psychosocial care provided by their informal networks and official response services. There is a need to better understand their experiences of distress and psychosocial care needs.

The aims of our study were to enhance understanding of the experience of distress among people present at the Manchester Arena bombing in 2017, identify their experiences of psychosocial care after the incident and learn how to better deliver and target effective psychosocial care following major incidents.

We conducted a thematic analysis of semi-structured interviews with 18 physically non-injured survivors of the Manchester Arena attack, who registered with the NHS Manchester Resilience Hub.

Distress was ubiquitous, with long-lasting health and social consequences. Initial reluctance to seek help from services was also common. Early and open access to authoritative sources of information and emotional support, and organised events for survivors, were viewed as helpful interventions. Inappropriate forms of psychosocial and mental healthcare were common and potent stressors that affected coping and recovery.

This paper extends our understanding of how people react to major events. Provision for the large group of people who are distressed and require psychosocial care may be inadequate after many incidents. There is a substantial agenda for developing awareness of people's needs for psychosocial interventions, and training practitioners to deliver them. The findings have substantial implications for policy and service design.
