Clinical Trial Summary

Frontline healthcare 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: they can disrupt functioning and can contribute to post-traumatic 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 will test the effect of a digital imagery-competing task, a digital music-listening task and treatment as usual (TAU) for National Health Service (NHS) staff with intrusive memories of work-related traumatic events from the pandemic. We test the effect on the number of intrusive memories (primary outcome), and other clinical symptoms (PTSD, anxiety, depression, and insomnia), in addition to work functioning, general functioning and quality of life (secondary outcomes). Intervention feasibility, acceptability and implementation will also be explored (additional outcomes). We will recruit approximately 150 NHS staff (via the Intensive Care Society, social media and direct advertising by NHS Trusts) with intrusive memories of traumatic events experienced during the COVID-19 pandemic.

The study is funded by the Wellcome Trust (223016/Z/21/Z).

Description:

A statistical analysis plan will be prepared prior to the first interim analysis using Bayesian analyses for statistical inference.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes to health and work	The 9-item questionnaire will be used to assess the occurrence and number of any new traumatic events, any additional stressful life events (e.g. relationship problems, financial problems), new treatments received, untoward medical occurrences, changes to the job, or changes to the number of hours worked per week since the last assessment.	4 weeks, 12 weeks and 24 weeks (all arms)
Other	Feedback questionnaire	A 12-item questionnaire assessing participants' experience of using the brief cognitive task. The first ten items assess how easy, helpful, distressing, burdensome and acceptable participants found the brief cognitive task, how willing they would be to use it in the future, how confident they would be in recommending it to a friend and how much they feel it could be used to support staff within the NHS, each rated from 0 (not at all) to 10 (very). The last two items ask how the brief cognitive task could be improved, and for any other comments or suggestions about the brief cogntive task, both with an open response.	After 4 weeks (brief imagery-competing task and brief music listening task arms only)
Other	Optional qualitative interview	This semi-structured interview will consist of a number of questions designed to gain an in-depth understanding of participants' experience of using the brief cognitive task, including acceptability, improvement suggestions, and potential barriers/facilitators to implementation.	At 4 weeks and at 12-24 weeks (brief imagery competing task and brief music listening task arms only)
Primary	Number of intrusive memories of traumatic event(s)	Number of intrusive memories of traumatic event(s) recorded by participants in a brief daily online diary for 7 days.	Week 4 (all arms) controlling for run-in/baseline week
Secondary	Number of intrusive memories of traumatic event(s)	Number of intrusive memories of traumatic event(s) recorded by participants in a brief daily online diary for 7 days.	Weeks 12 and 24 (all arms) controlling for run-in/baseline week
Secondary	PTSD Checklist for DSM-5 (PCL-5)	This 20-item measure assesses symptoms of PTSD over the last week. Items are rated on a 5-point scale ranging from 0 ("not at all") to 4 ("extremely"). Scores are summed to give a total severity score (ranging 0 to 80).	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Sleep Condition Indicator (SCI)	This 2-item scale measures sleep problems against the DSM-5 criteria for insomnia disorder. Item responses are each scored 0-4, with scores from 0 to 2 indicating threshold criteria for insomnia disorder. Total score ranges 0-8, with a higher score indicating better sleep.	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Generalised Anxiety Disorder 2-item scale (GAD-2)	This 2-item short-form self-report measure assesses symptoms of anxiety. Items are rated for how often they have bothered the respondent over the last two weeks, from 0 ("not at all") to 3 ("nearly every day"). Total score is the sum of both items and ranges from 0 to 6.	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Patient Health Questionnaire 2-item version (PHQ-2)	This 2-item short-form self-report measure assesses symptoms of depression. Items are rated for how often they have bothered the respondent over the last two weeks, from 0 ("not at all") to 3 ("nearly every day"). Total score is the sum of both items and ranges from 0 to 6.	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Scale of Work Engagement and Burnout (SWEBO)	This 19-item self-report measure assesses work engagement and burnout. The work engagement subscale consists of 10 items assessing three dimensions (vigour, attentiveness, dedication). The burnout subscale consists of 9 items assessing three dimensions (exhaustion, disengagement and inattentiveness). Respondents rate how often they have felt each descriptive in the past two weeks, from 1 (not at all) to 4 (all the time). The mean score is calculated for each subscale.	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Sickness absence	Single item assessing self-reported number of sick days taken from work in the last 4 weeks.	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Intention to leave job	3 items assess participants' intention to leave their job e.g. "I think a lot about leaving the job", each rated from 1 (strongly agree) to 5 (strongly disagree). The total score ranges 3 to 15, with a lower score indicating stronger intention to leave the job.	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	5-level European Quality of Life 5 Dimension (EQ-5D-5L)	The 5-level version of the EuroQol-5D (EQ-5D-5L) is a brief measure for assessing general quality of life and health status. Items assess mobility, self-care, usual activities, pain/discomfort and anxiety/depression each on a 5-point scale. 5 items are scored on a 5-point ordinal scale from 'no problem' (1) to 'highest level of problems' (5). Respondents also rate their overall health today from 0 (the worst health you can imagine) to 100 (the best health you can imagine). Scores are analysed separately (not summed).	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	World Health Organization Disability Assessment Schedule 12-item version (WHODAS 2.0)	The 12-item, self-report version of the WHODAS 2.0 will be used to assess difficulties in relation to the impact of intrusive memories. Respondents rate how much difficulty they have had in each area in the past 30 days, from 0 (none) to 4 (extreme or cannot do). The overall score is calculated as a percentage of the maximum possible score (i.e., 48 points).	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
Secondary	Intrusive memory ratings	The 9-item questionnaire assesses a number of intrusive memories characteristics. These characteristics include frequency (7-point categorical response from 'never' to 'many times a day'); distress (0=not at all to 10=extremely); disruption to concentration (0=not at all to 10=extremely); interference with what you were doing (how much (0=not at all to 10=extremely) and for how long (6-point categorical response from '<1min' to '>60mins')); impact on work functioning (how much (0=not at all to 10=extremely) and in what ways (open text response)); impact on functioning in other areas of life (how much (0=not at all to 10=extremely) and in what ways (open text response)).	Baseline, 4 weeks, 12 weeks and 24 weeks (all arms)
