High-flow nasal oxygen for children's airway surgery to reduce hypoxaemic events: a randomised controlled trial.

BACKGROUND: Tubeless upper airway surgery in children is a complex procedure in which surgeons and anaesthetists share the same operating field. These procedures are often interrupted for rescue oxygen therapy. The efficacy of nasal high-flow oxygen to decrease the frequency of rescue interruptions in children undergoing upper airway surgery is unknown. METHODS: In this multicentre randomised trial conducted in five tertiary hospitals in Australia, children aged 0-16 years who required tubeless upper airway surgery were randomised (1:1) by a web-based randomisation tool to either nasal high-flow oxygen delivery or standard oxygen therapy (oxygen flows of up to 6 L/min). Randomisation was stratified by site and age (<1 year, 1-4 years, and 5-16 years). Subsequent tubeless upper airway surgery procedures in the same child could be included if there were more than 2 weeks between the procedures, and repeat surgical procedures meeting this condition were considered to be independent events. The oxygen therapy could not be masked, but the investigators remained blinded until outcome data were locked. The primary outcome was successful anaesthesia without interruption of the surgical procedure for rescue oxygenation. A rescue oxygenation event was defined as an interruption of the surgical procedure to deliver positive pressure ventilation using either bag mask technique, insertion of an endotracheal tube, or laryngeal mask to improve oxygenation. There were ten secondary outcomes, including the proportion of procedures with a hypoxaemic event (SpO2 <90%). Analyses were done on an intention-to-treat (ITT) basis. Safety was assessed in all enrolled participants. This trial is registered in the Australian New Zealand Clinical Trials Registry, ACTRN12618000949280, and is completed. FINDINGS: From Sept 4, 2018, to April 12, 2021, 581 procedures in 487 children were randomly assigned to high-flow oxygen (297 procedures) or standard care (284 procedures); after exclusions, 528 procedures (267 assigned to high-flow oxygen and 261 assigned to standard care) in 483 children (293 male and 190 female) were included in the ITT analysis. The primary outcome of successful anaesthesia without interruption for tubeless airway surgery was achieved in 236 (88%) of 267 procedures on high-flow oxygen and in 229 (88%) of 261 procedures on standard care (adjusted risk ratio [RR] 1·02, 95% CI 0·96-1·08, p=0·82). There were 51 (19%) procedures with a hypoxaemic event in the high-flow oxygen group and 57 (22%) in the standard care group (RR 0·86, 95% CI 0·58-1·24). Of the other prespecified secondary outcomes, none showed a significant difference between groups. Adverse events of epistaxis, laryngospasm, bronchospasm, hypoxaemia, bradycardia, cardiac arrest, hypotension, or death were similar in both study groups. INTERPRETATION: Nasal high-flow oxygen during tubeless upper airway surgery did not reduce the proportion of interruptions of the procedures for rescue oxygenation compared with standard care. There were no differences in adverse events between the intervention groups. These results suggest that both approaches, nasal high-flow or standard oxygen, are suitable alternatives to maintain oxygenation in children undergoing upper airway surgery.

Cost-effectiveness of nasal high-flow in children with acute hypoxaemic respiratory failure.

AIM: A pilot randomised controlled trial assessed the early application of nasal high-flow (NHF) therapy compared with standard oxygen therapy (SOT), in children aged 0 to 16 years presenting to paediatric emergency departments with acute hypoxaemic respiratory failure (AHRF). The study estimated the need to escalate therapy and hospital length of stay in the NHF group compared with SOT. This sub-study then assessed the subsequent cost-effectiveness. METHODS: A decision tree-based model was developed, alongside the clinical study, to estimate cost-effectiveness, from the healthcare sector perspective. The primary health economics outcome is measured as incremental cost per length of hospital stay avoided. Incremental cost effectiveness ratios (ICER) measuring change in cost per change in length of stay, were obtained for four samples, depending on responder status and obstructive airways disease. These were (1) obstructive and responder, (2) non-obstructive and responder, (3) obstructive and non-responder and (4) non obstructive and non-responder. Bootstrapping of parameters accounted for uncertainty in estimates of cost and outcome. RESULTS: The ICER for patients randomised to NHF, indicated an additional A$367.20 for a lower hospital length of stay (in days) in the non-obstructive/non-responder sample. In the bootstrap sample, this was found to be cost effective above a willingness to pay threshold of A$10 000. The ICER was A$440.86 in the obstructive/responder sample and A$469.56 in the non-obstructive/responder sample - but both resulted in a longer length of stay. The ICER in the obstructive/non-responder sample was A$52 167.76, also with a longer length of stay, mainly impacted by a small sample of severe cases. CONCLUSION: As first-line treatment, NHF is unlikely to be cost-effective compared with SOT, but for non-obstructive patients who required escalation in care (non-obstructive non-responder), NHF is likely to be cost-effective if willingness-to-pay per reduced hospital length of stay is more than A$10 000 per patient.

Nasal High Flow Therapy for Bronchiolitis.

AIM: Uptake of nasal high-flow therapy in infants with bronchiolitis has grown in the last decade with some evidence suggesting a reduction in escalation of care. The effect of the implementation of recent available evidence on clinical practice remains unclear. METHODS: In a prospective observational study over 6 months in six metropolitan hospitals in Australia, we investigated the clinical practice of high-flow in infants admitted with bronchiolitis and an oxygen requirement. To assess the choice by clinicians of the initial oxygen therapy (standard oxygen or high-flow) the disease severity was measured by physiological parameters obtained prior to oxygen therapy commencement. Additional secondary outcomes were hospital length of stay and transfers to intensive care. RESULTS: Two hundred thirty-five infants with bronchiolitis were admitted for oxygen therapy over 6 months during the winter season. Infants who received high-flow on admission to hospital displayed significantly higher respiratory rates, higher heart rates and higher early warning tool scores with more severe work of breathing than those commenced on standard oxygen therapy as a first line of oxygen therapy. A significantly longer hospital length of stay of 0.6 days occurred in infants commenced on high-flow. A significantly greater proportion on high-flow (23.3%) were admitted to intensive care compared to infants commenced on SOT (10.4%) despite the severity of disease in both groups being similar. CONCLUSIONS: Infants with bronchiolitis presenting with greater disease severity are more likely to receive high-flow therapy. Escalation of care in an intensive care unit occurred more frequently on infants on high-flow. TRIAL REGISTRATION: This trial is registered in the Australian New Zealand Clinical Trial Registry ACTRN12618001206213.

Perception and appropriation of a web-based recovery narratives intervention: qualitative interview study.

Introduction: Mental health recovery narratives are widely available to the public, and can benefit people affected by mental health problems. The NEON Intervention is a novel web-based digital health intervention providing access to the NEON Collection of recovery narratives. The NEON Intervention was found to be effective and cost-effective in the NEON-O Trial for people with nonpsychosis mental health problems (ISRCTN63197153), and has also been evaluated in the NEON Trial for people with psychosis experience (ISRCTN11152837). We aimed to document NEON Intervention experiences, through an integrated process evaluation. Methods: Analysis of interviews with a purposive sample of intervention arm participants who had completed trial participation. Results: We interviewed 34 NEON Trial and 20 NEON-O Trial participants (mean age 40.4 years). Some users accessed narratives through the NEON Intervention almost daily, whilst others used it infrequently or not at all. Motivations for trial participation included: exploring the NEON Intervention as an alternative or addition to existing mental health provision; searching for answers about mental health experiences; developing their practice as a mental health professional (for a subset who were mental health professionals); claiming payment vouchers. High users (10 + narrative accesses) described three forms of appropriation: distracting from difficult mental health experiences; providing an emotional boost; sustaining a sense of having a social support network. Most participants valued the scale of the NEON Collection (n = 659 narratives), but some found it overwhelming. Many felt they could describe the characteristics of a desired narrative that would benefit their mental health. Finding a narrative meeting their desires enhanced engagement, but not finding one reduced engagement. Narratives in the NEON Collection were perceived as authentic if they acknowledged the difficult reality of mental health experiences, appeared to describe real world experiences, and described mental health experiences similar to those of the participant. Discussion: We present recommendations for digital health interventions incorporating collections of digital narratives: (1) make the scale and diversity of the collection visible; (2) provide delivery mechanisms that afford appropriation; (3) enable contributors to produce authentic narratives; (4) enable learning by healthcare professionals; (5) consider use to address loneliness.

The impact of reduced routine community mental healthcare on people from minority ethnic groups during the COVID-19 pandemic: qualitative study of stakeholder perspectives.

BACKGROUND: Enduring ethnic inequalities exist in mental healthcare. The COVID-19 pandemic has widened these. AIMS: To explore stakeholder perspectives on how the COVID-19 pandemic has increased ethnic inequalities in mental healthcare. METHOD: A qualitative interview study of four areas in England with 34 patients, 15 carers and 39 mental health professionals from National Health Service (NHS) and community organisations (July 2021 to July 2022). Framework analysis was used to develop a logic model of inter-relationships between pre-pandemic barriers and COVID-19 impacts. RESULTS: Impacts were largely similar across sites, with some small variations (e.g. positive service impacts of higher ethnic diversity in area 2). Pre-pandemic barriers at individual level included mistrust and thus avoidance of services and at a service level included the dominance of a monocultural model, leading to poor communication, disengagement and alienation. During the pandemic remote service delivery, closure of community organisations and media scapegoating exacerbated existing barriers by worsening alienation and communication barriers, fuelling prejudice and division, and increasing mistrust in services. Some minority ethnic patients reported positive developments, experiencing empowerment through self-determination and creative activities. CONCLUSIONS: During the COVID-19 pandemic some patients showed resilience and developed adaptations that could be nurtured by services. However, there has been a reduction in the availability of group-specific NHS and third-sector services in the community, exacerbating pre-existing barriers. As these developments are likely to have long-term consequences for minority ethnic groups' engagement with mental healthcare, they need to be addressed as a priority by the NHS and its partners.

Nasal high flow therapy in remote hospitals: guideline development using a modified Delphi technique.

INTRODUCTION: In remote Australian hospitals there are no onsite paediatric intensive care units (PICUs), increasing the reliance on aeromedical retrieval to access tertiary care. Nasal high flow (NHF) therapy is an oxygen therapy used in tertiary hospitals to treat paediatric patients with respiratory conditions. In rural and remote Queensland, Australia, the use of NHF therapy is inconsistent and there are no guidelines on how this therapy should be implemented in practice. Therefore, three remote hospitals within the Torres Strait and Cape York commenced a project to improve consistent and equitable access to NHF therapy. Implementing NHF therapy in remote hospitals may improve health and social outcomes for children with acute respiratory distress. A clinical guideline for the use of NHF therapy in the three participating remote hospitals was published on 28 October 2021. This study aimed to develop a clinical guideline for the use of NHF therapy in three remote hospitals. METHODS: A modified Delphi technique was used to develop the guideline. Remote medicine and nursing clinicians at the three study sites, retrieval experts, a receiving tertiary-based paediatrician, PICU specialists and NHF therapy experts made up the expert panel of participants. These experts participated in an iterative round table discussion to develop remote-specific guidelines for the use of NHF therapy. Prior to the meeting, panellists were provided with an executive summary of the current literature on NHF therapy implementation with key questions for consideration. Participants were able to add relevant issues ad hoc. A final guideline representing the panellists' recommendations was submitted to the Torres and Cape Health Service for ratification. RESULTS: Remote-specific decisions on the following topics were produced: environment of care, nasogastric tube usage, timings of chest X-ray, automatic approvals to arrange courier services for pathology, medication use, staff training; staff ratios, observations regimes, both tertiary and local medical consultation frequency and the experience level of the medical officer required to attend to these consultations, location of the on-call medical officer, documentation, escalation of care considerations and disposition of the patient in relation to retrievals. DISCUSSION: Decisions were made to mitigate two highly representative remote factors: delays in the workplace practices, such as time to arrange treatment locally and delays in retrievals; and burden of the lack of access to services, such as lack of access to trained staff, staffing levels on-shift, adequate oxygen and equipment/consumable supplies. CONCLUSION: The aim was to develop a clinical guideline that was contextualised to the remote hospital. This outcome was achieved by using a modified Delphi technique, with a panel of experts providing the decision-making for the guideline. Consistency and safety were addressed by reducing delays in workplace practices; examples were time to arrange treatment locally and mitigate delays in an unknown time to retrievals, access to trained staff, staffing levels, and communication between remote and tertiary teams.

Effectiveness and cost-effectiveness of online recorded recovery narratives in improving quality of life for people with non-psychotic mental health problems: a pragmatic randomized controlled trial.

Narratives describing first-hand experiences of recovery from mental health problems are widely available. Emerging evidence suggests that engaging with mental health recovery narratives can benefit people experiencing mental health problems, but no randomized controlled trial has been conducted as yet. We developed the Narrative Experiences Online (NEON) Intervention, a web application providing self-guided and recommender systems access to a collection of recorded mental health recovery narratives (n=659). We investigated whether NEON Intervention access benefited adults experiencing non-psychotic mental health problems by conducting a pragmatic parallel-group randomized trial, with usual care as control condition. The primary endpoint was quality of life at week 52 assessed by the Manchester Short Assessment (MANSA). Secondary outcomes were psychological distress, hope, self-efficacy, and meaning in life at week 52. Between March 9, 2020 and March 26, 2021, we recruited 1,023 participants from across England (the target based on power analysis was 994), of whom 827 (80.8%) identified as White British, 811 (79.3%) were female, 586 (57.3%) were employed, and 272 (26.6%) were unemployed. Their mean age was 38.4±13.6 years. Mood and/or anxiety disorders (N=626, 61.2%) and stress-related disorders (N=152, 14.9%) were the most common mental health problems. At week 52, our intention-to-treat analysis found a significant baseline-adjusted difference of 0.13 (95% CI: 0.01-0.26, p=0.041) in the MANSA score between the intervention and control groups, corresponding to a mean change of 1.56 scale points per participant, which indicates that the intervention increased quality of life. We also detected a significant baseline-adjusted difference of 0.22 (95% CI: 0.05-0.40, p=0.014) between the groups in the score on the "presence of meaning" subscale of the Meaning in Life Questionnaire, corresponding to a mean change of 1.1 scale points per participant. We found an incremental gain of 0.0142 quality-adjusted life years (QALYs) (95% credible interval: 0.0059 to 0.0226) and a £178 incremental increase in cost (95% credible interval: -£154 to £455) per participant, generating an incremental cost-effectiveness ratio of £12,526 per QALY compared with usual care. This was lower than the £20,000 per QALY threshold used by the National Health Service in England, indicating that the intervention would be a cost-effective use of health service resources. In the subgroup analysis including participants who had used specialist mental health services at baseline, the intervention both reduced cost (-£98, 95% credible interval: -£606 to £309) and improved QALYs (0.0165, 95% credible interval: 0.0057 to 0.0273) per participant as compared to usual care. We conclude that the NEON Intervention is an effective and cost-effective new intervention for people experiencing non-psychotic mental health problems.

Intensivists' Reported Management of Critical Bronchiolitis: More Data and New Guidelines Needed.

OBJECTIVES: Existing bronchiolitis guidelines do not reflect the needs of infants admitted to the PICU. This study aimed to identify PICU providers' reported practice variations and explore the need for critical bronchiolitis clinical guidelines. METHODS: Cross-sectional electronic survey available in English, Spanish, and Portuguese between November 2020 and March 2021, distributed via research networks from North and Latin America, Asia, and Australia/New Zealand. RESULTS: A total of 657 PICU providers responded, including 344 English, 204 Spanish, and 109 Portuguese. PICU providers indicated frequently using (≥25% of time) diagnostic modalities for nonintubated and intubated patients on PICU admission (complete blood count [75%-97%], basic metabolic panel [64%-92%], respiratory viral panel [90%-95%], chest x-ray [83%-98%]). Respondents also reported regularly (≥25% of time) prescribing ß-2 agonists (43%-50%), systemic corticosteroids (23%-33%), antibiotics (24%-41%), and diuretics (13%-41%). Although work of breathing was the most common variable affecting providers' decision to initiate enteral feeds for nonintubated infants, hemodynamic status was the most common variable for intubated infants (82% of providers). Most respondents agreed it would be beneficial to have specific guidelines for infants with critical bronchiolitis who are requiring both noninvasive (91% agreement) and invasive (89% agreement) respiratory support. CONCLUSIONS: PICU providers report performing diagnostic and therapeutic interventions for infants with bronchiolitis more frequently than recommended by current clinical guidelines, with interventions occurring more frequently for infants requiring invasive support. More clinical research is needed to inform the creation of evidence-based guidelines specifically for infants with critical bronchiolitis.

Improving mental healthcare access and experience for people from minority ethnic groups: an England-wide multisite experience-based codesign (EBCD) study.

BACKGROUND: Long-standing ethnic inequalities in access and mental healthcare were worsened by the COVID-19 pandemic. OBJECTIVES: Stakeholders coproduced local and national implementation plans to improve mental healthcare for people from minority ethnic groups. METHODS: Experience-based codesign conducted in four areas covered by National Health Service (NHS) mental health trusts: Coventry and Warwickshire, Greater Manchester, East London and Sheffield. Data were analysed using an interpretivist-constructivist approach, seeking validation from participants on their priority actions and implementation plans. Service users (n=29), carers (n=9) and health professionals (n=33) took part in interviews; focus groups (service users, n=15; carers, n=8; health professionals, n=24); and codesign workshops (service users, n=15; carers, n=5; health professionals, n=21) from July 2021 to July 2022. FINDINGS: Each study site identified 2-3 local priority actions. Three were consistent across areas: (1) reaching out to communities and collaborating with third sector organisations; (2) diversifying the mental healthcare offer to provide culturally appropriate therapeutic approaches and (3) enabling open discussions about ethnicity, culture and racism. National priority actions included: (1) co-ordination of a national hub to bring about system level change and (2) recognition of the centrality of service users and communities in the design and provision of services. CONCLUSIONS: Stakeholder-led implementation plans highlight that substantial change is needed to increase equity in mental healthcare in England. CLINICAL IMPLICATIONS: Working with people with lived experience in leadership roles, and collaborations between NHS and community organisations will be essential. Future research avenues include comparison of the benefits of culturally specific versus generic therapeutic interventions.

Assessing Diversity and Inclusivity is the Next Frontier in Mental Health Recovery Narrative Research and Practice.

Demand for digital health interventions is increasing in many countries. The use of recorded mental health recovery narratives in digital health interventions is becoming more widespread in clinical practice. Mental health recovery narratives are first-person lived experience accounts of recovery from mental health problems, including struggles and successes over time. Helpful impacts of recorded mental health recovery narratives include connectedness with the narrative and validation of experiences. Possible harms include feeling disconnected and excluded from others. Diverse narrative collections from many types of narrators and describing multiple ways to recover are important to maximize the opportunity for service users to benefit through connection and to minimize the likelihood of harm. Mental health clinicians need to know whether narrative collections are sufficiently diverse to recommend to service users. However, no method exists for assessing the diversity and inclusivity of existing or new narrative collections. We argue that assessing diversity and inclusivity is the next frontier in mental health recovery narrative research and practice. This is important, but methodologically and ethically complex. In this viewpoint, we propose and evaluate one diversity and two inclusivity assessment methods. The diversity assessment method involves use of the Simpson Diversity Index. The two inclusivity assessment methods are based on comparator demographic rates and arbitrary thresholds, respectively. These methods were applied to four narrative collections as a case study. Refinements are needed regarding a narrative assessment tool in terms of its practicality and cultural adaptation.

Effect of Early High-Flow Nasal Oxygen vs Standard Oxygen Therapy on Length of Hospital Stay in Hospitalized Children With Acute Hypoxemic Respiratory Failure: The PARIS-2 Randomized Clinical Trial.

Importance: Nasal high-flow oxygen therapy in infants with bronchiolitis and hypoxia has been shown to reduce the requirement to escalate care. The efficacy of high-flow oxygen therapy in children aged 1 to 4 years with acute hypoxemic respiratory failure without bronchiolitis is unknown. Objective: To determine the effect of early high-flow oxygen therapy vs standard oxygen therapy in children with acute hypoxemic respiratory failure. Design, Setting, and Participants: A multicenter, randomized clinical trial was conducted at 14 metropolitan and tertiary hospitals in Australia and New Zealand, including 1567 children aged 1 to 4 years (randomized between December 18, 2017, and March 18, 2020) requiring hospital admission for acute hypoxemic respiratory failure. The last participant follow-up was completed on March 22, 2020. Interventions: Enrolled children were randomly allocated 1:1 to high-flow oxygen therapy (n = 753) or standard oxygen therapy (n = 764). The type of oxygen therapy could not be masked, but the investigators remained blinded until the outcome data were locked. Main Outcomes and Measures: The primary outcome was length of hospital stay with the hypothesis that high-flow oxygen therapy reduces length of stay. There were 9 secondary outcomes, including length of oxygen therapy and admission to the intensive care unit. Children were analyzed according to their randomization group. Results: Of the 1567 children who were randomized, 1517 (97%) were included in the primary analysis (median age, 1.9 years [IQR, 1.4-3.0 years]; 732 [46.7%] were female) and all children completed the trial. The length of hospital stay was significantly longer in the high-flow oxygen group with a median of 1.77 days (IQR, 1.03-2.80 days) vs 1.50 days (IQR, 0.85-2.44 days) in the standard oxygen group (adjusted hazard ratio, 0.83 [95% CI, 0.75-0.92]; P < .001). Of the 9 prespecified secondary outcomes, 4 showed no significant difference. The median length of oxygen therapy was 1.07 days (IQR, 0.50-2.06 days) in the high-flow oxygen group vs 0.75 days (IQR, 0.35-1.61 days) in the standard oxygen therapy group (adjusted hazard ratio, 0.78 [95% CI, 0.70-0.86]). In the high-flow oxygen group, there were 94 admissions (12.5%) to the intensive care unit compared with 53 admissions (6.9%) in the standard oxygen group (adjusted odds ratio, 1.93 [95% CI, 1.35-2.75]). There was only 1 death and it occurred in the high-flow oxygen group. Conclusions and Relevance: Nasal high-flow oxygen used as the initial primary therapy in children aged 1 to 4 years with acute hypoxemic respiratory failure did not significantly reduce the length of hospital stay compared with standard oxygen therapy.

Predictors of Intensive Care Admission in Hypoxemic Bronchiolitis Infants, Secondary Analysis of a Randomized Trial.

OBJECTIVES: To evaluate in a preplanned secondary analysis of our parent randomized controlled trial predictors of intensive care unit (ICU) admission in infants with bronchiolitis and analyze if these predictors are equally robust for children receiving high-flow or standard-oxygen. STUDY DESIGN: A secondary analysis of a multicenter, randomized trial of infants aged <12 months with bronchiolitis and an oxygen requirement was performed using admission and outcome data of all 1472 enrolled infants. The primary outcome was ICU admission. The predictors evaluated were baseline characteristics including physiological data and medical history. RESULTS: Of the 1472 enrolled infants, 146 were admitted to intensive care. Multivariate predictors of ICU admission were age (weeks) (OR: 0.98 [95% CI: 0.96-0.99]), pre-enrolment heart rate >160/min (OR: 1.80 [95% CI: 1.23-2.63]), pre-enrolment SpO2 (transcutaneous oxygen saturation) (%) (OR: 0.91 [95% CI: 0.86-0.95]), previous ICU admission (OR: 2.16 [95% CI: 1.07-4.40]), and time of onset of illness to hospital presentation (OR: 0.78 [95% CI: 0.65-0.94]). The predictors were equally robust for infants on high-flow nasal cannula therapy or standard-oxygen therapy. CONCLUSION: Age <2 months, pre-enrolment heart rate >160/min, pre-enrolment SpO2 of <87%, previous ICU admission and time of onset of ≤2 days to presentation are predictive of an ICU admission during the current hospital admission of infants with bronchiolitis independent of oxygenation method used.

[1,4]Ditellurino[2,3-b:5,6-b']di-pyrazine.

[1,4]Ditellurino[2,3-b:5,6-b']di-pyrazine represents the first reported [1,4]chalcogena[2,3-b:5,6-b']di-pyrazine containing a heavy chalcogens The asymmetric unit consists of three mol-ecules. In contrast to its sulfur analog, which is planar [Lynch et al. (1994 ▸) Cryst. Struct. Commun. 50,1470-1472], C8H4N4Te2 is folded along the Te⋯Te axis to accommodate the larger chalcogenide atoms. The dihedral angle between the two Te2C2 rings of the central ring is 57.9° (mean of three). C-Te bond lengths range from 2.1105 (16) Što 2.1381 (17) Å, in good agreement with those predicted by their covalent radii. All Te atoms are involved in inter-molecular Te⋯N contacts, with distances in the range 2.894 (2) to 2.963 (2) Å. These result in a spiral supra-molecular assembly, forming helical columns.

'Maybe I Shouldn't Talk': The Role of Power in the Telling of Mental Health Recovery Stories.

Mental health 'recovery narratives' are increasingly used within teaching, learning and practice environments. The mainstreaming of their use has been critiqued by scholars and activists as a co-option of lived experience for organisational purposes. But how people report their experiences of telling their stories has not been investigated at scale. We present accounts from 71 people with lived experience of multiple inequalities of telling their stories in formal and informal settings. A reflexive thematic analysis was conducted within a critical constructivist approach. Our overarching finding was that questions of power were central to all accounts. Four themes were identified: (1) Challenging the status quo; (2) Risky consequences; (3) Producing 'acceptable' stories; (4) Untellable stories. We discuss how the concept of narrative power foregrounds inequalities in settings within which recovery stories are invited and co-constructed, and conclude that power imbalances complicate the seemingly benign act of telling stories of lived experience.

Typology of content warnings and trigger warnings: Systematic review.

Content and trigger warnings give information about the content of material prior to receiving it. Different typologies of content warnings have emerged across multiple sectors, including health, social media, education and entertainment. Benefits arising from their use are contested, with recent empirical evidence from educational sectors suggesting they may raise anxiety and reinforce the centrality of trauma experience to identity, whilst benefits relate to increased individual agency in making informed decisions about engaging with content. Research is hampered by the absence of a shared inter-sectoral typology of warnings. The aims of this systematic review are to develop a typology of content warnings and to identify the contexts in which content warnings are used. The review was pre-registered (ID: CRD42020197687, URL: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020197687) and used five sources: electronic databases covering multiple sectors (n = 19); table of contents from multi-sectoral journals (n = 5), traditional and social media websites (n = 53 spanning 36 countries); forward and backward citation tracking; and expert consultation (n = 15). In total, 6,254 documents were reviewed for eligibility and 136 documents from 32 countries were included. These were synthesised to develop the Narrative Experiences Online (NEON) content warning typology, which comprises 14 domains: Violence, Sex, Stigma, Disturbing content, Language, Risky behaviours, Mental health, Death, Parental guidance, Crime, Abuse, Socio-political, Flashing lights and Objects. Ten sectors were identified: Education, Audio-visual industries, Games and Apps, Media studies, Social sciences, Comic books, Social media, Music, Mental health, and Science and Technology. Presentation formats (n = 15) comprised: education materials, film, games, websites, television, books, social media, verbally, print media, apps, radio, music, research, DVD/video and policy document. The NEON content warning typology provides a framework for consistent warning use and specification of key contextual information (sector, presentation format, target audience) in future content warning research, allowing personalisation of content warnings and investigation of global sociopolitical trends over time.

Uses and Misuses of Recorded Mental Health Lived Experience Narratives in Healthcare and Community Settings: Systematic Review.

Mental health lived experience narratives are first-person accounts of people with experience of mental health problems. They have been published in journals, books and online, and used in healthcare interventions and anti-stigma campaigns. There are concerns about their potential misuse. A four-language systematic review was conducted of published literature characterizing uses and misuses of mental health lived experience narratives within healthcare and community settings. 6531 documents in four languages (English, Danish, Swedish, Norwegian) were screened and 78 documents from 11 countries were included. Twenty-seven uses were identified in five categories: political, societal, community, service level and individual. Eleven misuses were found, categorized as relating to the narrative (narratives may be co-opted, narratives may be used against the author, narratives may be used for different purpose than authorial intent, narratives may be reinterpreted by others, narratives may become patient porn, narratives may lack diversity), relating to the narrator (narrator may be subject to unethical editing practises, narrator may be subject to coercion, narrator may be harmed) and relating to the audience (audience may be triggered, audience may misunderstand). Four open questions were identified: does including a researcher's personal mental health narrative reduce the credibility of their research?: should the confidentiality of narrators be protected?; who should profit from narratives?; how reliable are narratives as evidence?).

Post-traumatic growth in psychosis: a systematic review and narrative synthesis.

BACKGROUND AND OBJECTIVE: People with psychosis report experiences of highly traumatic events. Positive change or post-traumatic growth (PTG) can occur as a result of traumatic experiences. Yet there is limited attention on PTG in psychosis, possibly due to the negative impact of psychotic symptoms on functioning and quality of life. The aim of this review was to identify significant correlates and mediators of PTG in psychosis, and to develop a conceptual framework synthesising facilitators of PTG in psychosis. METHOD: Ten electronic databases were searched in seven languages, and five journals and grey literature were searched in English. Quantitative studies were eligible if examining correlates, mediators, or the temporal relationship between PTG and one or more variables. Qualitative studies were eligible if describing PTG arising from experiences of psychosis. Findings from quantitative papers were grouped by analysis method, with significant correlates, mediators, and temporal relationships descriptively reported upon. Narrative synthesis was conducted on findings in qualitative papers. RESULTS: Thirty-seven papers were included. Significant correlates and mediators of PTG were identified. Mediators of PTG in psychosis included meaning in life, coping self-efficacy, core beliefs, and self-reported recovery. No studies describing the temporal relationship between PTG and psychosis were identified. The narrative synthesis identified seven facilitators of PTG in psychosis: Personal identity and strength, Receiving support, Opportunities and possibilities, Strategies for coping, Perspective shift, Emotional experience, and Relationships, giving the acronym PROSPER. CONCLUSIONS: Individuals with psychosis can be supported to grow from traumatic experiences. Clinicians can support PTG through the provision of trauma-informed care that supports positively valued identity changes. For researchers, the findings provide an evidence-based theoretical framework for conceptualising PTG, which can be validated through longitudinal cohort studies and underpin the development of new clinical interventions.

Institutional injustice: Implications for system transformation emerging from the mental health recovery narratives of people experiencing marginalisation.

BACKGROUND: Institutional injustice refers to structures that create disparities in resources, opportunities and representation. Marginalised people experience institutional injustice, inequalities and discrimination through intersecting personal characteristics and social circumstances. This study aimed to investigate sources of institutional injustice and their effects on marginalised people with experience of mental health problems. METHODS: Semi-structured interviews were conducted with 77 individuals from marginalised groups with experience of mental health problems, including psychosis, Black, Asian and minority ethnic (BAME) populations, complex needs and lived experience as a work requirement. These were analysed inductively enabling sensitising concepts to emerge. FINDINGS: Three processes of institutional injustice were identified: not being believed because of social status and personal backgrounds; not being heard where narratives did not align with dominant discourses, and not being acknowledged where aspects of identity were disregarded. Harmful outcomes included disengagement from formal institutions through fear and mistrust, tensions and reduced affiliation with informal institutions when trying to consolidate new ways of being, and damaging impacts on mental health and wellbeing through multiple oppression. CONCLUSIONS: Institutional injustice perpetuates health inequalities and marginalised status. Master status, arising from dominant discourses and heuristic bias, overshadow the narratives and experiences of marginalised people. Cultural competency has the potential to improve heuristic availability through social understandings of narrative and experience, whilst coproduction and narrative development through approaches such as communities of practice might offer meaningful avenues for authentic expression.
