简要总结
During the COVID-19 pandemic, clinical staff working in frontline NHS hospital and pre-hospital departments (e.g. emergency department, intensive care unit, ambulance service) are being faced with difficult and stressful situations, which may be traumatic to them. Staff report high rates of post-traumatic stress symptoms, such as intrusive memories of these incidents, which 'pop into their mind' unexpectedly, are distressing and can impact on work performance. Currently there is a lack of tailored evidence-based interventions for staff struggling with intrusive memories of work-related traumatic events: simple, accessible, remotely-delivered interventions are needed. An intervention which has been found to be effective in reducing intrusive memories is a simple cognitive task that involves briefly bringing to mind the memory and then playing the computer game Tetris with specific ("mental rotation") instructions. This case series study aims to test the intervention in a group of 8-20 staff members working clinically in NHS hospital and pre-hospital departments. The intervention will be delivered remotely (via computer/smartphone/tablet/phone). Participants will record the number of intrusive memories daily over a 3-week period, with the intervention delivered after 1 week (with optional subsequent booster sessions). Symptoms of trauma, anxiety and depression will be assessed weekly over this period, and at 4 weeks after the intervention. It is predicted that participants will have fewer intrusive memories per day/week, and lower clinical symptoms scores, after completing the intervention than before completing the intervention. The study will also investigate how feasible and acceptable the intervention is for NHS staff. Findings will inform the next steps in developing and evaluating a digital intervention to reduce intrusive memories of work-related traumatic events in healthcare staff.

结局指标
主要结局
Change in the number of intrusive memories of traumatic event
时间窗: Change from baseline to post-intervention, in line with case series design. The baseline period and the post-intervention period were defined separately for each intrusive memory, according to when that intrusion was first targeted with the intervention.
Number of intrusive memories of traumatic event recorded by participants in a brief electronic daily diary.
次要结局
- Impact of Events Scale-Revised score (IES-R; Weiss & Marmar, 1997)(Weekly for 6 weeks: 2 weeks pre-intervention to 4 weeks post-intervention)
- The Generalised Anxiety Disorder scale (GAD-7; Spitzer, Kroenke, Williams & Löwe, 2006)(Weekly for 6 weeks: 2 weeks pre-intervention to 4 weeks post-intervention)
- Change in retrospective ratings of intrusive memory characteristics over the last week(At 1 week pre-intervention, and at 4 weeks post-intervention)
- The Patient Health Questionnaire Depression scale (PHQ-9; Kroenke, Spitzer, & Williams, 2001)(Weekly for 6 weeks: 2 weeks pre-intervention to 4 weeks post-intervention)
- The Pittsburgh Sleep Quality Index (PSQI; Buysse, 1989)(At 1 week pre-intervention, and at 4 weeks post-intervention)
- Changes in ratings of intrusive memory characteristics(Change between baseline and post-intervention, in line with case series design)
