Treating intrusive memories after trauma in healthcare workers: a Bayesian adaptive randomised trial developing an imagery-competing task intervention.

Intensive care unit (ICU) staff continue to face recurrent work-related traumatic events throughout the COVID-19 pandemic. Intrusive memories (IMs) of such traumatic events comprise sensory image-based memories. Harnessing research on preventing IMs with a novel behavioural intervention on the day of trauma, here we take critical next steps in developing this approach as a treatment for ICU staff who are already experiencing IMs days, weeks, or months post-trauma. To address the urgent need to develop novel mental health interventions, we used Bayesian statistical approaches to optimise a brief imagery-competing task intervention to reduce the number of IMs. We evaluated a digitised version of the intervention for remote, scalable delivery. We conducted a two-arm, parallel-group, randomised, adaptive Bayesian optimisation trial. Eligible participants worked clinically in a UK NHS ICU during the pandemic, experienced at least one work-related traumatic event, and at least three IMs in the week prior to recruitment. Participants were randomised to receive immediate or delayed (after 4 weeks) access to the intervention. Primary outcome was the number of IMs of trauma during week 4, controlling for baseline week. Analyses were conducted on an intention-to-treat basis as a between-group comparison. Prior to final analysis, sequential Bayesian analyses were conducted (n = 20, 23, 29, 37, 41, 45) to inform early stopping of the trial prior to the planned maximum recruitment (n = 150). Final analysis (n = 75) showed strong evidence for a positive treatment effect (Bayes factor, BF = 1.25 × 106): the immediate arm reported fewer IMs (median = 1, IQR = 0-3) than the delayed arm (median = 10, IQR = 6-16.5). With further digital enhancements, the intervention (n = 28) also showed a positive treatment effect (BF = 7.31). Sequential Bayesian analyses provided evidence for reducing IMs of work-related trauma for healthcare workers. This methodology also allowed us to rule out negative effects early, reduced the planned maximum sample size, and allowed evaluation of enhancements.

Using a Novel Gameplay Intervention to Target Intrusive Memories After Work-Related Trauma: Iterative Qualitative Analysis of Intensive Care Unit Staff Experiences.

BACKGROUND: Many intensive care unit (ICU) staff experience intrusive memories following work-related traumatic events, which can lead to long-term mental health outcomes and impact work functioning. There is a need for interventions that target intrusive memories in this population; however, factors such as mental health stigma and difficulty in fitting interventions into busy schedules can pose barriers. The Brief Gameplay Intervention For National Health Service Intensive Care Unit Staff Affected By COVID-19 Trauma (GAINS) study tested a brief, digital imagery-competing task intervention (including computer gameplay) with the aim of reducing the recurrence of intrusive memories, which holds promise for overcoming some of these barriers. OBJECTIVE: This substudy aims to explore barriers and facilitators to the uptake and practical use of the intervention by ICU staff, along with its acceptability, and iteratively explore the impact of intervention optimizations to further refine the intervention. METHODS: The GAINS study is a randomized controlled trial comparing access to a brief digital imagery-competing task intervention for 4 weeks with usual care followed by delayed access to the intervention. The participants were ICU staff who worked during the COVID-19 pandemic and experienced intrusive memories. All participants were sent a questionnaire at 4 weeks to gather data about intervention acceptability. Nested within the randomized controlled trial, a subset of 16 participants was interviewed, and data were analyzed using thematic analysis drawing from a framework approach. RESULTS: Both quantitative and qualitative data indicated high acceptability of the intervention. Intervention use data show that, on average, staff were able to target approximately 73% (3.64/4.88) of their intrusive memories and engaged with the Tetris component for the full 20 minutes per session. Overall, on the acceptability questionnaire, staff found the intervention easy to use, helpful, and highly acceptable. The interviews generated four themes: approach to the intervention, positives of the intervention, negatives of the intervention, and improvements and optimizations. Findings highlighted barriers that ICU staff experienced: stigma, feeling weak for seeking help, not wanting colleagues to know they were struggling, and skepticism. However, they provided suggestions on how barriers could be overcome and discussed the advantages of the intervention when compared with other treatments. Although participants described many positive aspects of the intervention, such as being easy to use, enjoyable, and leading to a reduction in the frequency or intensity of intrusive memories, they also raised practical issues for implementation. CONCLUSIONS: The intervention has the potential to overcome stigma and reduce the frequency of intrusive memories after traumatic events among ICU staff. Further refinement is needed to improve the adoption and reach of this intervention. A limitation is that we could not interview the National Health Service staff who were unable or unwilling to take part in the trial.

Mixed-methods randomised study exploring the feasibility and acceptability of eye-movement desensitisation and reprocessing for improving the mental health of traumatised survivors of intensive care following hospital discharge: protocol.

INTRODUCTION: Post-traumatic symptoms are common among patients discharged from intensive care units (ICUs), adversely affecting well-being, increasing healthcare utilisation and delaying return to work. Non-pharmacological approaches (eg, music, therapeutic touch and patient diaries) have been suggested as candidate interventions and trauma-focused psychological interventions have been endorsed by international bodies. Neither category of intervention is supported by definitive evidence of long-term clinical effectiveness in patients who have been critically ill. This study assesses the feasibility and acceptability of using eye-movement desensitisation and reprocessing (EMDR) to improve the mental health of ICU survivors. METHODS AND ANALYSIS: EMERALD is a multicentre, two-part consent, pilot feasibility study, recruiting discharged ICU survivors from three hospitals in the UK. We are gathering demographics and measuring post-traumatic symptoms, anxiety, depression and quality of life at baseline. Two months after discharge, participants are screened for symptoms of post-traumatic stress disorder (PTSD) using the Impact of Events Scale-Revised (IES-R). Patients with IES-R scores<22 continue in an observation arm for 12 month follow-up. IES-R scores≥22 indicate above-threshold PTSD symptoms and trigger invitation to consent for part B: a randomised controlled trial (RCT) of EMDR versus usual care, with 1:1 randomisation. The study assesses feasibility (recruitment, retention and intervention fidelity) and acceptability (through semistructured interviews), using a theoretical acceptability framework. Clinical outcomes (PTSD, anxiety, depression and quality of life) are collected at baseline, 2 and 12 months, informing power calculations for a definitive RCT, with quantitative and qualitative data convergence guiding RCT refinements. ETHICS AND DISSEMINATION: This study has undergone external expert peer review and is funded by the National Institute for Health and Care Research (grant number: NIHR302160). Ethical approval has been granted by South Central-Hampshire A Research Ethics Committee (IRAS number: 317291). Results will be disseminated through the lay media, social media, peer-reviewed publication and conference presentation. TRIAL REGISTRATION NUMBER: NCT05591625.

Team Immediate Meet tool to help intensive care staff: Staff perception of an updated version and preliminary feedback following implementation.

Intensive Care Unit staff deal with potentially traumatic cases throughout their careers. We designed and implemented a 'Team Immediate Meet' (TIM) tool, a communication aid designed to facilitate a two-minute 'hot debrief' after a critical event, provide the team with information about the normal reaction to such an event and signpost staff to strategies to help support their colleagues (and themselves). We describe our TIM tool awareness campaign, quality improvement project and subsequent feedback from staff who reported that the tool would be useful for navigating the aftermath of potentially traumatic events and could be transferable to other ICUs.

Therapy professionals in critical care: A UK wide workforce survey.

Introduction: National guidelines suggest recommended staffing levels for therapies. The aim of this study was to capture information on existing staffing levels, roles and responsibilities and service structures. Methods: An observational study using online surveys distributed to 245 critical care units across the United Kingdom (UK). Surveys consisted of a generic and five profession specific surveys. Results: Eight hundred sixty-two responses were received from 197 critical care units across the UK. Of those that responded, over 96% of units had input from dietetics, physiotherapy and SLT. Whereas only 59.1% and 48.1% had an OT or psychology service respectively. Units with ring fenced services had improved therapist to patient ratios. Discussion: There is significant variation in access to therapists for patients admitted to critical care in the UK, with many services not having services for core therapies such as psychology and OT. Where services do exist, they fall below the recommended guidance.

Reducing intrusive memories after trauma via an imagery-competing task intervention in COVID-19 intensive care staff: a randomised controlled trial.

Intrusive memories (IMs) after traumatic events can be distressing and disrupt mental health and functioning. We evaluated the impact of a brief remotely-delivered digital imagery-competing task intervention on the number of IMs for intensive care unit (ICU) staff who faced repeated trauma exposure during the COVID-19 pandemic using a two-arm, parallel-group, single-blind randomised controlled trial, with the comparator arm receiving delayed access to active treatment (crossover). Eligible participants worked clinically in a UK NHS ICU during the pandemic and had at least 3 IMs of work-related traumatic events in the week before recruitment. Participants were randomly assigned (1:1) to immediate (weeks 1-4) or delayed (weeks 5-8) intervention access. Sequential Bayesian analyses to optimise the intervention and increase trial efficiency are reported elsewhere [1]. The primary endpoint for the pre-specified frequentist analysis of the final study population compared the number of IMs experienced in week 4 between the immediate and delayed access arms. Secondary outcomes included clinical symptoms, work functioning and wellbeing. Safety was assessed throughout the trial by scheduled questions and free report. All analyses were undertaken on an intention-to-treat basis (86 randomised participants). There were significantly fewer intrusive memories during week 4 in the immediate (median = 1, IQR = 0-3, n = 43), compared to the comparator delayed arm (median = 10, IQR = 6-17, n = 43), IRR 0.31, 95% CI: 0.20-0.48, p < 0.001. After crossover, the delayed arm also showed a significant reduction in IMs at week 8 compared to week 4. There were convergent findings for symptoms of PTSD, insomnia and anxiety, work engagement and burnout, general functioning and quality of life. The intervention was found safe and acceptable to participants. All adverse events were unrelated to the study. Our study provides the first evidence of a benefit on reducing IMs, improving other clinical symptoms, work functioning and wellbeing, as well as safety of a brief remotely-delivered digital imagery-competing task intervention. An efficacy trial with an active control and longer follow-up is warranted. The trial is registered at ClinicalTrials.gov (NCT04992390).

The Post-ICU presentation screen (PICUPS) and rehabilitation prescription (RP) for intensive care survivors part II: Clinical engagement and future directions for the national Post-Intensive care Rehabilitation Collaborative.

Background: Many Intensive Care Unit (ICU) survivors suffer from a multi- system disability, termed the post-intensive care syndrome. There is no current national coordination of either rehabilitation pathways or related data collection for them. In the last year, the need for tools to systematically identify the multidisciplinary rehabilitation needs of severely affected COVID-19 survivors has become clear. Such tools offer the opportunity to improve rehabilitation for all critical illness survivors through provision of a personalised Rehabilitation Prescription (RP). The initial development and secondary refinement of such an assessment and data tools is described in the linked paper. We report here the clinical and workforce data that was generated as a result. Methods: Prospective service evaluation of 26 acute hospitals in England using the Post-ICU Presentation Screen (PICUPS) tool and the RP. The PICUPS tool comprised items in domains of a) Medical and essential care, b) Breathing and nutrition; c) Physical movement and d) Communication, cognition and behaviour. Results: No difference was seen in total PICUPS scores between patients with or without COVID-19 (77 (IQR 60-92) vs. 84 (IQR 68-97); Mann-Whitney z = -1.46, p = 0.144. A network analysis demonstrated that requirements for physiotherapy, occupational therapy, speech and language therapy, dietetics and clinical psychology were closely related and unaffected by COVID-19 infection status. A greater proportion of COVID-19 patients were referred for inpatient rehabilitation (13% vs. 7%) and community-based rehabilitation (36% vs.15%). The RP informed by the PICUPS tool generally specified a greater need for multi-professional input when compared to rehabilitation plans instituted. Conclusions: The PICUPS tool is feasible to implement as a screening mechanism for post-intensive care syndrome. No differences are seen in the rehabilitation needs of patients with and without COVID-19 infection. The RP could be the vehicle that drives the professional interventions across the transitions from acute to community care. No single discipline dominates the rehabilitation requirements of these patients, reinforcing the need for a personalised RP for critical illness survivors.

The post-ICU presentation screen (PICUPS) and rehabilitation prescription (RP) for intensive care survivors part I: Development and preliminary clinimetric evaluation.

Background: Patients who have had prolonged stays in intensive care have ongoing rehabilitation needs. This is especially true of COVID-19 ICU patients, who can suffer diverse long-term ill effects. Currently there is no systematic data collection to guide the needs for therapy input for either of these groups nor to inform planning and development of rehabilitation services. These issues could be resolved in part by the systematic use of a clinical tool to support decision-making as patients progress from the Intensive Care Unit (ICU), through acute hospital care and onwards into rehabilitation. We describe (i) the development of such a tool (the Post-ICU Presentation Screen (PICUPS)) and (ii) the subsequent preparation of a person-centred Rehabilitation Prescription (RP) to travel with the patient as they continue down the care pathway. Methods: PICUPS development was led by a core group of experienced clinicians representing the various disciplines involved in post-ICU rehabilitation. Key constructs and item-level descriptors were identified by group consensus. Piloting was performed as part of wider clinical engagement in 26 acute hospitals across England. Development and validation of such a tool requires clinimetric analysis, and this was based on classical test theory. Teams also provided feedback about the feasibility and utility of the tool. Results: Initial PICUPS design yielded a 24-item tool. In piloting, a total of 552 records were collated from 314 patients, of which 121 (38.5%) had COVID-19. No obvious floor or ceiling effects were apparent. Exploratory factor analysis provided evidence of uni-dimensionality with strong loading on the first principal component accounting for 51% of the variance and Cronbach's alpha for the full-scale score 0.95 - although a 3-factor solution accounted for a further 21%. The PICUPS was responsive to change both at full scale- and item-level. In general, positive responses were seen regarding the tool's ability to describe the patients during their clinical course, engage and flag the relevant professionals needed, and to inform what should be included in an RP. Conclusions: The PICUPS tool has robust scaling properties as a clinical measure and is potentially useful as a tool for identifying rehabilitation needs as patients step down from ICU and acute hospital care.

Staff wellbeing in times of COVID-19.

In the last 10 years, there has been increasing interest into the psychological wellbeing of healthcare providers. Within critical care, increasing attention is being paid to the concept of 'burnout' - a cluster of symptoms that adversely affect the health of critical care providers. Publications and statements from the major critical care societies have all addressed this syndrome and emphasised urgency in tackling it. The current COVID-19 pandemic has fundamentally changed the way we work, communicate and learn. Even before the pandemic, there have been growing concerns and acknowledgement that healthcare practitioners in intensive care are at increased risk of burnout and burnout syndrome. There has never been greater pressure on intensive care or indeed healthcare as a whole to look after so many patients during this pandemic and yet there is global acknowledgement that key to overcoming these challenges is to look after the care providers - both physically and psychologically. In this paper, we review the issue of burnout amongst healthcare practitioners during current pandemic. We present the impact of burnout on the individual and the system as a whole but perhaps most importantly, we provide a review of steps being taken to mitigate against these adverse outcomes in the short and longer term.

Exploration of therapists' views of practice within critical care.

INTRODUCTION: Therapists are increasing recognised as core members of the critical care multiprofessional team. Each therapy profession provides specialist assessments and interventions, but also work collaboratively across the rehabilitation pathway. Despite inclusion in several national guidance documents, there remains a lack of evidence regarding the perceived role of therapists working within critical care, the unique contributions of each profession and opinion on the day-to-day tasks and responsibilities of each therapy profession. METHOD: A descriptive qualitative methodology was used involving seven focus groups. Purposeful sampling was used to recruit therapists via professional specialist interest groups. All focus groups were uniprofessional and discussions based on a predesigned framework. Data were analysed thematically. RESULTS: Participants (n=65) from across the UK were recruited to seven focus groups with an average of 18.3 years postgraduate clinical experience of which 11.6 years was within critical care. Three core themes were generated from 875 codes and 237 potential subthemes. The final themes were (1) professional characteristics; (2) multidisciplinary team and (3) staffing. An additional theme of 'COVID-19 pandemic' was also identified. Findings were similar across all profession groups particularly regarding the need for holistic, patient-centred care. Expected variation was observed for professional characteristics especially regarding specific assessments and interventions. DISCUSSION: Therapy services are an essential component to the delivery of critical care especially regarding recovery and rehabilitation. Through three core themes, this qualitative study has provided new evidence of the perceptions and opinions of the role that therapists undertake within critical care.

An investigation into the experience of self-conscious emotions in individuals with bipolar disorder, unipolar depression and non-psychiatric controls.

UNLABELLED: There has been little research into the association of shame and other self-conscious emotions in bipolar disorder, although there is evidence linking shame to various psychopathologies. OBJECTIVES: This research investigates the levels of shame in individuals with bipolar disorder. DESIGN AND METHODS: A cross-sectional design was used to compare 24 individuals with a diagnosis of bipolar disorder to a clinical control group of 18 individuals with unipolar depression, and 23 age-matched non-psychiatric controls on measures of mood (Beck Depression Inventory [BDI] and Self Report Manic Inventory [SRMI]) and of self-conscious emotions (Internalized Shame Scale and Test of Self-Conscious Affect). RESULTS: Higher levels of trait shame and lower guilt-proneness were found in the bipolar group. Higher levels of shame-proneness were found in the unipolar group in comparison to the bipolar and control groups. BDI scores positively correlated with trait shame and shame-proneness, and accounted for a large proportion of the variance in these scores. SRMI scores positively correlated with trait (internalized) shame and negatively correlated with guilt-proneness. CONCLUSIONS: There was evidence for the presence of shame within bipolar disorder, but this differed to the evidence for shame in individuals with unipolar depression. Clinical implications are discussed.

Professional Quality of Life in intensive care medicine: The 2018 Faculty of Intensive Care Medicine Workforce survey.

BACKGROUND: Critical care is widely perceived, both within and outside of the speciality, as unremitting and emotionally burdensome. There is a perception of a higher risk to medical staff of burnout than other specialities. Critical care also has considerable emotional and professional rewards. We sought to examine this balance between emotional reward and stress in UK critical care consultants registered with the Faculty of Intensive Care Medicine. METHOD: We conducted a Wellbeing survey of the Faculty of Intensive Care Medicine consultant membership utilising the Professional Quality of Life (Pro-QOL) survey tool. The survey was conducted as part of the Annual Workforce Census. RESULTS: In sum, 799 members completed the Pro-QOL survey, making this one of the largest surveys of physician wellbeing in critical care medicine. Data were analysed in accordance with the Pro-QOL manual. CONCLUSIONS: The results demonstrate moderate risk for burnout and secondary traumatic stress, but this is balanced by moderate compassion satisfaction. No association was demonstrated between age, sex, or size of critical care unit worked in. Further follow-up of this consultant group is warranted to better understand risk factors for burnout and for future mitigation of these risk factors whilst also enhancing the positive aspects of working as a consultant in critical care medicine.

Stress and Fear: Clinical Implications for Providers and Patients (in the Time of COVID-19 and Beyond).

In light of the coronavirus disease 2019 pandemic, we explore the role of stress, fear, and the impact of positive and negative emotions on health and disease. We then introduce strategies to help mitigate stress within the health care team, and provide a rationale for their efficacy. Additionally, we identify strategies to optimize patient care and explain their heightened importance in today's environment.

Burnout Syndrome in UK Intensive Care Unit staff: Data from all three Burnout Syndrome domains and across professional groups, genders and ages.

INTRODUCTION: This is the first comprehensive evaluation of Burnout Syndrome across the UK Intensive Care Unit workforce and in all three Burnout Syndrome domains: Emotional Exhaustion, Depersonalisation and lack of Personal Accomplishment. METHODS: A questionnaire was emailed to UK Intensive Care Society members, incorporating the 22-item Maslach Burnout Inventory Human Services Survey for medical personnel. Burnout Syndrome domain scores were stratified by 'risk'. Associations with gender, profession and age-group were explored. RESULTS: In total, 996 multi-disciplinary responses were analysed. For Emotional Exhaustion, females scored higher and nurses scored higher than doctors. For Depersonalisation, males and younger respondents scored higher. CONCLUSION: Approximately one-third of Intensive Care Unit team-members are at 'high-risk' for Burnout Syndrome, though there are important differences according to domain, gender, age-group and profession. This data may encourage a more nuanced understanding of Burnout Syndrome and more personalised strategies for our heterogeneous workforce.

The experience of the long-term doctor-patient relationship in consultant nephrologists.

BACKGROUND: There is evidence to suggest that the long-term doctor-patient relationship is crucial in the management of chronic illness such as chronic kidney disease. While previous research has focused on patient views of the doctor-patient relationship, research exploring the doctor's experiences of this unique dynamic is lacking, leading to a gap in our understanding. Therefore, an enhanced appreciation of the experience of the doctor is important and could have potential implications for medical training and service organisation. OBJECTIVES: In this paper, we report the first known study exploring the experience of consultant nephrologists in the long-term doctor-patient relationship. PARTICIPANTS AND DESIGN: Seven male consultant nephrologists (mean age of 48 years) took part in semi-structured interviews, and data were analysed using interpretative phenomenological analysis (IPA). RESULTS: Three main themes were identified from the analysis: 'Defining my professional identity', 'Relating to the patient' and 'Coping with the job'. CONCLUSION: Participants had difficulty in defining their role as doctors, discussing themselves as being more than a doctor and comparing themselves with other medical specialties to help them define their identity. Although participants enjoyed forming long-term relationships with patients and the closeness this involved, they discussed the acute scenarios of saving lives as the most rewarding aspect of their job and used coping mechanisms that enabled them to remain detached in the relationship.

Stability of self-esteem in bipolar disorder: comparisons among remitted bipolar patients, remitted unipolar patients and healthy controls.

OBJECTIVES: Changes in beliefs about the self are a central feature of bipolar disorder, with grandiose self-belief common in mania and low self-esteem evident in periods of depression. We investigated whether unstable self-esteem is a characteristic of bipolar disorder in remission. METHODS: We compared 18 patients with DSM-IV bipolar disorder in remission, 16 patients with unipolar disorder in remission, and 19 healthy controls. The primary measure was a diary kept for one week and completed twice each day, measuring self-esteem and positive and negative affect. We also administered Winters and Neale's (J Abnorm Psychol 1985; 94: 282-290) implicit measure of attributional style. RESULTS: Whereas mean levels of self-esteem and affect were not abnormal in the remitted bipolar patients, the bipolar patients showed strong fluctuations in these processes. In common with the unipolar patients, they also showed a pessimistic attributional style on the Pragmatic Inference Task (PIT). CONCLUSIONS: Instability of self-esteem and affect is present in bipolar patients, even when their symptoms are in remission, and has previously been found in people at genetic risk of the disorder. It may be a marker of vulnerability to the disorder.
