Transferability of psychological interventions from disaster-exposed employees to healthcare workers working during the COVID-19 pandemic - update to a systematic review and secondary analysis

Background: The COVID-19 Pandemic had a significant negative impact on the mental health of healthcare workers (HCWs). Evidence-based interventions that could be used to mitigate this impact are lacking in the literature. This review aims to evaluate psychological interventions used for employees following previous disasters and assess the transferability of these interventions to a healthcare setting during the COVID-19 pandemic.

Methods: Intervention information from a previously published systematic review of the literature published up to 2015 was extracted, and an additional search of studies published from 2015–2020 was conducted. Studies were assessed for transferability using a checklist derived from the PIET-T process model.

Results: Interventions from eighteen studies were assessed for transferability (including three studies identified in an updated literature search). Interventions established as most transferable included resilience training, meditation/mindfulness interventions, and cognitive behavioural therapy. Psychological debriefing was transferable but as it is contrary to current recommendations is not deemed appropriate for adoption.

Conclusions: Several existing interventions have the potential to be utilised within the COVID-19 context/pandemic. More research needs to be undertaken in this area to assess these interventions upon transfer.
