a brief gameplay intervention for nhs icu staff affected by covid-19 trauma (gains study)

Conditions: Intrusive Memories of Traumatic Event(s)

Summary: intensive care unit (icu) staff are frequently exposed to traumatic events at work (e.g., witnessing patients die), amplified by the covid-19 pandemic. a significant proportion experience intrusive memories of these events that pop suddenly into mind: these imagery-based memories can disrupt functioning and contribute to posttraumatic stress disorder. previous research has shown that a brief behavioural intervention can reduce the number of intrusive memories after a traumatic event. in this study we aim to optimise a brief digital intervention to help reduce the number of intrusive memories experienced by icu staff (primary outcome). we will explore if it can improve work functioning and wellbeing (secondary outcomes). we will recruit approximately 150 icu staff with intrusive memories of events experienced during the covid-19 pandemic. the study is funded by the wellcome trust (223016/z/21/z).

a statistical analysis plan will be prepared prior to the first interim analysis for the outcomes that will guide study optimisation, i.e., primarily the primary outcome. a second statistical analysis plan will be prepared prior to the end of the study, to outline the standard (frequentist) statistical approaches that will be used to analyse the primary, secondary and tertiary data. regular monitoring will be performed by p1vital products to verify that the study is conducted and data are generated, documented and reported in compliance with the protocol, gcp and the applicable regulatory requirements. quality assurance representatives from the sponsor may carry out an audit of the study in compliance with regulatory guidelines and relevant standard operating procedures.

Eligibility criteria:
inclusion criteria: * aged 18 or above. * able to read, write and speak in english. * worked in a clinical role in an nhs intensive care unit or equivalent during the covid-19 pandemic (e.g. as a member of icu staff or deployed to work in the icu during the pandemic) * experienced at least one traumatic event related to their work during the covid-19 pandemic, meeting criterion a of the diagnostic and statistical manual of mental disorders, 5th edition (dsm-5) criteria for post-traumatic stress disorder (ptsd): "exposure to actual or threatened death, serious injury, or sexual violence" by "directly experiencing the traumatic event(s)" or "witnessing, in person, the event(s) as it occurred to others" * experience intrusive memories of the traumatic event(s). * experienced at least three intrusive memories in the week prior to screening. * have internet access. * willing and able to provide informed consent and complete study procedures (including briefly listing their intrusive memories (without going into any detail), and playing the brief digital imagery-competing task with particular mental rotation instructions, and completing an online intrusive memory diary). * willing and able to be contacted by the research team during the study period. exclusion criteria: • have fewer than three intrusive memories during the run-in week. we will not exclude those undergoing other treatment for ptsd or its symptoms, so the study is as inclusive as possible to meet the challenges icu staff are facing during the covid-19 pandemic.
