Emphysematous gastritis is a severe form of gastritis caused by gas-forming infectious organisms and is most frequently encountered in critically unwell patients. Diagnosis rests on the radiographic appearances of air within the gastric wall, which may extend into the portal venous system. Not previously described in the context of neutropenic sepsis, our case involves a 77-year-old patient with emphysematous gastritis who was admitted to the intensive care unit with a neutrophil count of 0.1 × 10⁹/L and managed successfully with conservative treatment. Presenting complaints usually include abdominal pain, nausea, vomiting and occasionally haematemesis, in the context of systemic upset. Predisposing factors may include diabetes and immunosuppression, ingestion of corrosive substances, alcohol abuse, and abdominal surgery. The historical approach to management which previously involved urgent exploratory laparotomy with gastrectomy, has largely been replaced with conservative therapy, including broad-spectrum antimicrobials, gut rest and parenteral nutrition, with improved outcomes. Previously considered a commonly terminal diagnosis with mortality rates as high as 60%, this recent shift in approach to management has contributed to mortality rates being halved. The role of oesophago-gastro-duodenoscopy has not been established and is unlikely to be indicated in every case. Longterm complications may be of concern and include fibrosis and gastric contractures.

Background: Peer support groups reduce psychological morbidity and increase social support for Intensive Care Unit (ICU) survivors. Group formats differ and research, although emerging, is limited. This study explores a continuously running ICU Expert by Experience group, which has a dual role of support and service-user consultative, from attendees' perspectives.

Methods: A thematic analysis was conducted on interviews with current and past members of an ICU Expert by Experience group. 11 participants took part in online and telephone interviews. Three provided written responses. Final themes were created following a process of data validation with participants.

Results: Four main themes emerged: (1) Support in the difficult recovery journey (2) Relationships and shared experiences (3) Value of professional facilitation (4) Practical considerations.

Conclusion: Patients highlighted the help gained from the group as an integral part of their recovery journey. Results also identified practical implications for those considering setting up similar support groups.

Background: Approximately 50% of intensive care survivors experience persistent psychological symptoms. Eye-movement desensitisation and reprocessing (EMDR) is a widely recommended trauma-focussed psychological therapy, which has not been investigated systematically in a cohort of intensive care survivors: We therefore conducted a randomised pilot feasibility study of EMDR, using the Recent Traumatic Episode Protocol (R-TEP), to prevent psychological distress in intensive care survivors. Findings will determine whether it would be possible to conduct a fully-powered clinical effectiveness trial and inform trial design.

Method: We aimed to recruit 26 patients who had been admitted to intensive care for over 24 h with COVID-19 infection. Consenting participants were randomised (1:1) to receive either usual care plus remotely delivered EMDR R-TEP or usual care alone (controls). The primary outcome was feasibility. We also report factors related to safety and symptom changes in post-traumatic stress disorder, (PTSD) anxiety and depression.

Results: We approached 51 eligible patients, with 26 (51%) providing consent. Intervention adherence (sessions offered/sessions completed) was 83%, and 23/26 participants completed all study procedures. There were no attributable adverse events. Between baseline and 6-month follow-up, mean change in PTSD score was -8 (SD = 10.5) in the intervention group versus +0.75 (SD = 15.2) in controls (p = 0.126). There were no significant changes to anxiety or depression.

Conclusion: Remotely delivered EMDR R-TEP met pre-determined feasibility and safety objectives. Whilst we achieved group separation in PTSD symptom change, we have identified a number of protocol refinements that would improve the design of a fully powered, multi-centre randomised controlled trial, consistent with currently recommended rehabilitation clinical pathways.

Background: Current personal protective equipment (PPE) practices in UK intensive care units involve "sessional" use of long-sleeved gowns, risking nosocomial infection transmitted via gown sleeves. Data from the first wave of the COVID19 pandemic demonstrated that these changes in infection prevention and control protocols were associated with an increase in healthcare associated bloodstream infections. We therefore explored the use of a protocol using short-sleeved gowns with hand and arm hygiene to reduce this risk.

Methods: ICU staff were trained in wearing short-sleeved gowns and using a specific hand and arm washing technique between patients (experimental protocol). They then underwent simulation training, performing COVID-19 intubation and proning tasks using either experimental protocol or the standard (long-sleeved) control protocol. Fluorescent powder was used to simulate microbial contamination, detected using photographs under ultraviolet light. Teams were randomised to use control or experimental PPE first. During the simulation, staff were questioned on their feelings about personal safety, comfort and patient safety.

Results: Sixty-eight staff and 17 proning volunteers were studied. Experimental PPE completely prevented staff contamination during COVID-19 intubation, whereas this occurred in 30/67 staff wearing control PPE (p = .003, McNemar). Proning volunteers were contaminated by staff in 15/17 control sessions and in 1/17 with experimental PPE (p = .023 McNemar). Staff comfort was superior with experimental PPE (p< .001, Wilcoxon). Their personal safety perception was initially higher with control PPE, but changed towards neutrality during sessions (p < .001 start, 0.068 end). Their impressions of patient safety were initially similar (p = .87), but finished strongly in favour of experimental PPE (p < .001).

Conclusions: Short-sleeved gowns with hand and forearm cleansing appear superior to sessional long-sleeved gowns in preventing cross-contamination between staff and patients.

Background: Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a form of life support used in severe respiratory failure. While the short-term complications of VV-ECMO are well described, impacts on health-related quality of life (HRQOL) are less well characterised. This study aims to assess the HRQOL of patients who underwent VV-ECMO for acute severe respiratory failure and explore predictors of poor HRQOL.

Methods: We performed a retrospective, observational study of a large cohort of adults who underwent VV-ECMO for acute severe respiratory failure in a single tertiary centre (June 2013-March 2019). Patients surviving critical care discharge were invited to a six-month clinic, where they completed an EQ-5D-5L questionnaire assessing HRQOL. Multivariate analysis was performed to assess prognostic factors for HRQOL.

Results: Among the 245 consecutive patients included in this study (median age 45 years), 187 (76.3%) survived until ECMO decannulation and 172 (70.2%) until hospital discharge. Of those, 98 (57.3%) attended a follow-up clinic at a mean (±SD) of 204 (±45) days post-discharge. Patients reported problems with pain/discomfort (56%), usual daily activities (53%), anxiety/depression (49%), mobility (46%), and personal care (21%). Multivariate analysis identified limb ischaemia (-0.266, 95% C.I. [-0.116; -0.415], p = 0.0005), renal replacement therapy (-0.149, [-0.046; -0.252], p = 0.0044), and having received more than four platelet units (-0.157, [-0.031; -0.283], p = 0.0146) as predictors of poor HRQOL.

Conclusion: We report that survivors of VV-ECMO have reduced HRQOL in multiple domains at 6 months, with pain reported most frequently. Patients who had limb ischaemia, renal replacement therapy or were transfused more than four units of platelets are particularly at risk of poor HRQOL and may benefit from added support measures.

Background: The family members of intensive care unit (ICU) patients play a crucial role in modern ICUs. These individuals are predisposed to the development of post-intensive care syndrome in family members (PICS-F), a syndrome experienced by family members of ICU patients in response to critical illness and characterised by new or worsening psychological symptoms. This study sought to evaluate the levels of anxiety and depression exhibited by the family members of patients hospitalised in the ICU. It also aimed to identify the risk factors associated with the experience of PICS-F, which should assist with its prevention in the future.

Methods: The study sample comprised 164 ICU patients and their family members. Sociodemographic data were gathered at the time of ICU admission and 3 months after discharge, and the family members were screened for emotional distress using the Hospital Anxiety and Depression Scale (HADS). Comparison tests were used to test for an association between family/patient characteristics and a positive HADS score. In addition, a multivariable logistic regression model was constructed to identify the independent factors associated with a positive HADS score.

Results: Emotional distress was identified in 24% of the family members 3 months after their relatives had been discharged from the ICU. A number of personal traits were found to be associated with emotional distress in the family members, namely unemployment (p = .008), smoking/drinking habits (p = .036) and personal history of psychopathology (p = .045). In the multiple logistic regression analyses, only unemployment was found to be an independent factor associated with both anxiety and depression in the family members (OR = 2.74, CI 95%: 1.09-6.93). No association was found between the patients' characteristics and emotional distress in the family members.

Conclusions: The findings of this study indicate an association between emotional distress in the family members of ICU patients and their personal traits, thereby building on the prior literature by suggesting that patient characteristics are less pertinent to the experience of PICS-F. Unemployment may represent a meaningful risk factor for emotional distress in family members (a potential marker of PICS-F), given its relationship with family members' positive HADS scores post-ICU discharge. These findings should influence preventative strategies concerning PICS-F by illustrating the need to assess family characteristics and demographics early in a patient's ICU stay and, consequently, allowing for the early identification of at-risk individuals and the prompt implementation of adequate support services.

Intensivists are increasingly involved in the care of frail patients as our population ages. Careful person-orientated, individualised decision-making, weighing benefits and harms of critical care are required in such situations. Few studies have reported outcomes of patients with treatment limitations. This dual-centre observational study reports outcomes of 3781 patients (2018-20). At least one treatment limitation was set at admission in 13% (n = 486). Of this group 55% survived to hospital discharge, of whom 69% were discharged home; 39% remained alive at 1 year. These findings provide objective data to support clinicians, patients and relatives in shared decision-making. Future multi-centre work could explore how best to identify those most likely to benefit from critical care.

Background: Recent guidelines in the UK have shaped Critical Care Units (CCUs) to bring the mental health needs of patients, and staff wellbeing to the forefront of service provision. A health board based in NHS Wales has trialled the secondment of a Mental Health Nurse (RMN) within a CCU to help service provision adhere to such guidelines.

Methods: Critical care staff were invited to attend focus groups to share their experiences of how the RMN influenced service provision.

Results: Thematic analysis identified five main themes; including 'smoother care pathways', 'a holistic approach to care', 'co-production', 'knowledge and confidence' and 'staff wellbeing'. Each of these themes reflected how the RMN had both direct and indirect benefits on patient and staff wellbeing.

Conclusion: This qualitative exploration suggests that staff perceived value in the role of the RMN for both staff and patient outcomes, although further measures were considered necessary to improve staff-wellbeing within a critical care environment. This service evaluation supports recommendations for commissioning a RMN permanently in a CCU.
