Background

Menstrual health is essential for gender equity and the well-being of women and girls. Qualitative research has described the burden of poor menstrual health on health and education; however, these impacts have not been quantified, curtailing investment. The Adolescent Menstrual Experiences and Health Cohort (AMEHC) Study aims to describe menstrual health and its trajectories across adolescence, and quantify the relationships between menstrual health and girls’ health and education in Khulna, Bangladesh.

Methods and analysis

AMEHC is a prospective longitudinal cohort of 2016 adolescent girls recruited at the commencement of class 6 (secondary school, mean age=12) across 101 schools selected through a proportional random sampling approach. Each year, the cohort will be asked to complete a survey capturing (1) girls’ menstrual health and experiences, (2) support for menstrual health, and (3) health and education outcomes. Survey questions were refined through qualitative research, cognitive interviews and pilot survey in the year preceding the cohort. Girls’ guardians will be surveyed at baseline and wave 2 to capture their perspectives and household demographics. Annual assessments will capture schools’ water, sanitation and hygiene, and support for menstruation and collect data on participants’ education, including school attendance and performance (in maths, literacy). Cohort enrolment and baseline survey commenced in February 2023. Follow-up waves are scheduled for 2024, 2025 and 2026, with plans for extension. A nested subcohort will follow 406 post-menarche girls at 2-month intervals throughout 2023 (May, August, October) to describe changes across menstrual periods. This protocol outlines a priori hypotheses regarding the impacts of menstrual health to be tested through the cohort.

Ethics and dissemination

AMEHC has ethical approval from the Alfred Hospital Ethics Committee (369/22) and BRAC James P Grant School of Public Health Institutional Review Board (IRB-06 July 22-024). Study materials and outputs will be available open access through peer-reviewed publication and study web pages.

Spiritual coping within medical professions: A psychometric analysis of the Numinous Motivations Inventory short form

Abstract

Aim

To examine the psychometric properties of a short form version of the Numinous Motivation Inventory (NMI) for use with healthcare providers in measuring their existential engagement with life and to assess its relationship with spiritual coping and emotional dysphoria.

Design

Correlational and psychometric study.

Method

Data were collected from June to December 2022. Participants included 102 physicians, recruited from across the United States. Qualtrics was utilized to collect data, and they were evaluated with the NMI short form, Spiritual Coping Questionnaire and Depression, Anxiety, and Stress scale (DASS-21).

Results

Obtained fit statistics from structural equation modelling analysis indicated close fit of the NMI short form with the original model. Multiple regression analyses demonstrated the value of the NMI as a predictor of negative affect independent of spiritual coping. The NMI did not interact with Spiritual Coping, which was independent of negative affect.

Conclusions

The Numinous represents an important aspect of physicians' coping. The constructs can be utilized in training and clinical settings as a valuable and easy-to-use metric for promoting and assessing wellness. The implications of these findings and the value of the NMI were discussed.

Impact

An understanding of existential drivers can equip one to cope with the stressors of healthcare. The NMI short form has the capability to explore an individual's existential drivers through the understanding of three domains.

Reporting Method

Adhered to proper EQUATOR guidelines (GRRAS).

Public Contribution

A standardized wound infection model for antimicrobial testing of wound dressings in vitro

Abstract

To investigate the effectiveness of antimicrobial agents against wound infections, experiments using either 2D cultures with planktonic microorganisms or animal infection models are frequently carried out. However, the transferability of the results to human skin is limited by the lack of complexity of the 2D models or by the poor translation of the results from animal models. Hence, there is a need for wound infection models capable of assessing antimicrobial agents. In this study, an easily standardized wound infection model was established. This model consists of a mechanically wounded human skin model on a collagen matrix infected with various clinically relevant bacteria. Infection of the model led to recognition of the pathogens and induction of an inflammatory response. The untreated infection spread over time, causing significant tissue damage. By applying an antimicrobial-releasing wound dressing, the bacterial load could be reduced and the success of the treatment could be further measured by a decrease in the inflammatory reaction. In conclusion, this wound infection model can be used to evaluate new antimicrobial therapeutics as well as to study host-pathogen interactions.

Introduction

COVID-19 has caused severe disruption to clinical services in Bangladesh but the extent of this, and the impact on healthcare professionals is unclear. We aimed to assess the perceived levels of anxiety, depression and burnout among doctors and nurses during COVID-19 pandemic.

Methods

We undertook an online survey using RedCap, directed at doctors and nurses across four institutions in Bangladesh (The Sheikh Russel Gastro Liver Institute & Hospital (SRNGIH), Dhaka Medical College Hospital (DMCH), Mugda Medical College Hospital (MMCH) and M Abdur Rahim Medical College (MARMC) Hospital). We collected information on demographics, awareness of well-being services, COVID-19-related workload, as well as anxiety, depression and burnout using two validated questionnaires: the Hospital Anxiety and Depression Scale (HADS) and the Maslach Burnout Inventory (MBI).

Results

Of the 3000 participants approached, we received responses from 2705 (90.2%). There was a statistically significant difference in anxiety, depression and burnout scores across institutions (p

Conclusion

We identified a high prevalence of perceived anxiety, depression and burnout among doctors and nurses during the COVID-19 pandemic. This was worse in staff engaged in COVID-19-related activities. These findings could help healthcare organisations to plan for future similar events.

Por: Hirschwald · J. · Duncan · S. · Warnecke · T. · Boyle · G. · Regan · J. · Walshe · M.
Introduction

Current clinical trials on swallowing disorders (dysphagia) in Parkinson’s disease (PD) apply a high variety of outcomes and different outcome measures making comparative effectiveness research challenging. Furthermore, views of patients and dysphagia clinicians when selecting trial outcomes have not been considered in the past, thus study results may have little importance to them. This study aims to develop an agreed standardised Core Outcome Set for Dysphagia Interventions in Parkinson’s disease (COS-DIP), systematically measured and reported as a minimum for all clinical trials. It will also comprise guidance on outcome definitions, outcome measures and time points of measurement.

Methods and analysis

The COS-DIP development will comprise five stages following established methodology: (1) a recent scoping review on all applied outcomes, their definitions, methods and time points of measurement in clinical trials in dysphagia in PD, (2) online surveys and focus groups with clinicians, patients, caregivers and family members to identify outcomes that are important to them, (3) an identified list of outcomes based on results of stage 1 and 2, (4) three round online Delphi survey with up to 200 key stakeholders to determine core outcomes and (5) two online consensus meetings with up to 40 representative key stakeholders to agree on all outcomes, definitions, methods and time points of measurement in the final COS-DIP.

Ethics and dissemination

Full ethical approval was obtained from the Research Ethics Committee, School of Linguistic, Speech and Communication Sciences, Trinity College Dublin, on 15 May 2023 (HT27). Dissemination of the COS-DIP will be enhanced through presentations at (inter-) national conferences and through peer-reviewed, open access publications of related manuscripts. Lay and professional information sheets and infographics will be circulated through relevant patient and professional organisations and networks.

Trial registration number

The COS-DIP study was registered prospectively with the Core Outcome Measures in Effectiveness Trials (COMET) database on 24 September 2021 (www.comet-initiative.org/Studies/Details/1942).

Patient evaluation of gynaecological information provision and preferences

Abstract

Aim

To evaluate gynaecological patients' preferences and satisfaction regarding information provision, exploring enablers and barriers to information access.

Design

A descriptive cross-sectional survey design was used.

Methods

A total of 293 women accessing gynaecological services responded to the survey. Quantitative analysis included descriptive and inferential statistics. Content analysis was conducted on qualitative data.

Results

Health professionals were the most common and preferred sources of gynaecological health information. Enablers to information provision included positive communication strategies by health professionals, participants having prior knowledge and doing their own research. Despite its widespread availability, only 24.2% of women preferred the internet as an information source. Poor communication and inadequate information provision were identified as barriers to information access. Statistically significant associations were identified between location of residence, education level, year of birth, diagnostic group and health information preferences. Recommendations from women included improved communication strategies, system changes and provision of individualized information.

Conclusion

Health professionals are central to women accessing information about gynaecological diagnoses. Areas for improvement include communication strategies, facilitating access to internet-based resources for information and consideration of women's preferences when providing health information.

Implications for the Profession and Patient Care

Consumer co-design of gynaecological health information and communication training for health professionals is recommended. Improved communication and facilitated use of internet-based resources may improve women's understanding of information.

Impact

This study explored gynaecological patients' preferences and satisfaction regarding information provision, exploring enablers and barriers to information access. It was found that gynaecological patients preferred individualized information provided to them directly by health professionals and despite its widespread availability, the internet is an underutilized health information resource. These findings are applicable to health professionals and patients utilizing tertiary gynaecological health services in Australia but may be generalized if demographic data aligns with other jurisdictions.

Reporting Method

The STROBE reporting method was used in the preparation of the manuscript.

What are the views of adults with an intellectual disability (AWID), carers and healthcare professionals on a community falls management programme for AWID: a qualitative interview study in the UK

Por: Robinson · K. · Logan · P. · Tucker · C. · Finlayson · J. · van der Wardt · V. · Kilby · A. · Knowles · S. · Vanhegan · S. · Hodgson · S. · Lidstone · N.
Objectives

The aim of this study was to refine a draft of the ACTiON FALLS LD programme based on the views of adults with an intellectual disability (AWID), carers and healthcare professionals (HCPs).

Design, setting and participants

The semistructured interview study included HCP as well as AWID and carers supporting AWID living in the community. Community settings included sheltered living, supported living, AWID living at home with family carers or independently. The interview study explored the first draft of the ACTiON FALLS LD programme as well as the wider falls management for AWID. Interviews with AWID were developed to include a range of approaches (eg, case studies, pictures) to support inclusive participation. Individual interviews were digitally recorded and transcribed. Researcher notes were used during interviews with AWID. All data were analysed using the principles of framework analysis.

Results

14 HCP, 8 carers and 13 AWID took part in the interview process. Five key themes were identified: programme components, programme design, programme approach, who would use the programme and programme delivery.

Conclusions

The views of AWID, HCP and carers showed the need to consider the impact of risk perception, anxiety and fear of falling in the adaption of the ACTiON FALLS programme. The programme needs to be accessible and support the inclusion of AWID in managing falls and ultimately fulfil the requirement for a proactive and educational tool by all.

Effect of vitamin D on clinical outcomes in patients with thermal injury

Abstract

Evaluating complications and mortality risks in burn patients is crucial for effective treatment planning and improving survival rates. This study investigated the relationship between the serum vitamin D level and the clinical outcomes of adult burns patients. This was a prospective cohort of adult patients hospitalized due to thermal burns at a burn centre in the north of Iran. Based on the level of 25 hydroxyvitamin D measured upon admission, patients were divided into two groups of patients with sufficient 25 hydroxyvitamin D level and insufficient 25 hydroxyvitamin D level. Descriptive statistics were used for baseline demographics. Univariate analysis was conducted using Mann–Whitney U, Chi-square, independent samples, and Fisher's exact tests. A multivariate logistic regression was performed to adjust for the effects of confounding variables. Statistical analyses were conducted using SPSS 28.0 software. A total of 220 patients were included in the study. The average total body surface area burned was 30.52 ± 9.34. Patients with insufficient vitamin D levels had longer hospital stays (12.53 vs. 11.45) and longer stays in the intensive care unit (ICU) (3.32 vs. 2.40) than those with appropriate vitamin D levels. Participants with insufficient vitamin D levels exhibited a numerically higher incidence of infections than those with adequate levels (p < 0.05). The multivariate regression found that vitamin D deficiency levels were associated with increased infection rates and prolonged hospital stay. This study suggests that vitamin D deficiency is a significant risk factor for adverse clinical outcomes in burn patients. Further research is needed to confirm these associations and to explore potential interventions to optimize vitamin D status in this patient population.

High-resolution genomic analysis to investigate the impact of the invasive brushtail possum (<i>Trichosurus vulpecula</i>) and other wildlife on microbial water quality assessments

by Marie Moinet, Lynn Rogers, Patrick Biggs, Jonathan Marshall, Richard Muirhead, Megan Devane, Rebecca Stott, Adrian Cookson

Escherichia coli are routine indicators of fecal contamination in water quality assessments. Contrary to livestock and human activities, brushtail possums (Trichosurus vulpecula), common invasive marsupials in Aotearoa/New Zealand, have not been thoroughly studied as a source of fecal contamination in freshwater. To investigate their potential role, Escherichia spp. isolates (n = 420) were recovered from possum gut contents and feces and were compared to those from water, soil, sediment, and periphyton samples, and from birds and other introduced mammals collected within the Mākirikiri Reserve, Dannevirke. Isolates were characterized using E. coli-specific real-time PCR targeting the uidA gene, Sanger sequencing of a partial gnd PCR product to generate a gnd sequence type (gST), and for 101 isolates, whole genome sequencing. Escherichia populations from 106 animal and environmental sample enrichments were analyzed using gnd metabarcoding. The alpha diversity of Escherichia gSTs was significantly lower in possums and animals compared with aquatic environmental samples, and some gSTs were shared between sample types, e.g., gST535 (in 85% of samples) and gST258 (71%). Forty percent of isolates gnd-typed and 75% of reads obtained by metabarcoding had gSTs shared between possums, other animals, and the environment. Core-genome single nucleotide polymorphism (SNP) analysis showed limited variation between several animal and environmental isolates (Escherichia clones are shared between possums, other wildlife, water, and the wider environment. These findings support the potential role of possums as contributors to fecal contamination in Aotearoa/New Zealand freshwater. Our study deepens the current knowledge of Escherichia populations in under-sampled wildlife. It presents a successful application of high-resolution genomic methods for fecal source tracking, thereby broadening the analytical toolbox available to water quality managers. Phylogenetic analysis of isolates and profiling of Escherichia populations provided useful information on the source(s) of fecal contamination and suggest that comprehensive invasive species management strategies may assist in restoring not only ecosystem health but also water health where microbial water quality is compromised.

Occurrence and characteristics of extended-spectrum-β-lactamase- and pAmpC-producing <i>Klebsiella pneumoniae</i> isolated from companion animals with urinary tract infections

by Megan Min Yi Lee, Nan-Ling Kuan, Zhi-Yi Li, Kuang-Sheng Yeh

This study examined 70 Klebsiella pneumoniae isolates derived from companion animals with urinary tract infections in Taiwan. Overall, 81% (57/70) of the isolates carried extended-spectrum β-lactamase (ESBL) and/or plasmid-encoded AmpC (pAmpC) genes. ESBL genes were detected in 19 samples, with blaCTX-M-1, blaCTX-M-9, and blaSHV being the predominant groups. pAmpC genes were detected in 56 isolates, with blaCIT and blaDHA being the predominant groups. Multilocus sequence typing revealed that sequence types (ST)11, ST15, and ST655 were prevalent. wabG, uge, entB, mrkD, and fimH were identified as primary virulence genes. Two isolates demonstrated a hypermucoviscosity phenotype in the string test. Antimicrobial susceptibility testing exhibited high resistance to β-lactams and fluoroquinolones in ESBL-positive isolates but low resistance to aminoglycosides, sulfonamides, and carbapenems. Isolates carrying pAmpC genes exhibited resistance to penicillin-class β-lactams. These findings provide valuable insights into the role of K. pneumoniae in the context of the concept of One Health.

Stress and burnout amongst mental health professionals in Singapore during Covid-19 endemicity

by Suyi Yang, Germaine Ke Jia Tan, Kang Sim, Lucas Jun Hao Lim, Benjamin Yong Qiang Tan, Abhiram Kanneganti, Shirley Beng Suat Ooi, Lue Ping Ong

The COVID-19 pandemic has exerted a huge emotional strain on mental health professionals (MHP) in Singapore. As Singapore transited into an endemic status, it is unclear whether the psychological strain has likewise lessened. The aims of this study were to investigate the levels of stress and burnout experienced by MHP working in a tertiary psychiatric hospital in Singapore during this phase of COVID-19 endemicity (2022) in comparison to the earlier pandemic years (2020 and 2021) and to identify factors which contribute to as well as ameliorate stress and burnout. A total of 282 MHP participated in an online survey in 2022, which included 2 validated measures, namely the Perceived Stress Scale and the Oldenburg Burnout Inventory (OLBI). Participants were also asked to rank factors that contributed the most to their stress and burnout. Between-group comparisons were conducted regarding stress and burnout levels among MHP across different demographic groupings and working contexts. In addition, OLBI data completed by MHP in 2020 and 2021 were extracted from 2 published studies, and trend analysis was conducted for the proportion of MHP meeting burnout threshold across 3 time points. We found that the proportion of MHP meeting burnout threshold in 2020, 2021 and 2022 were 76.9%, 87.6% and 77.9% respectively. Professional groups, age, years of experience and income groups were associated with stress and/or burnout. High clinical workload was ranked as the top factor that contributed to stress and burnout while flexible working arrangement was ranked as the top area for improvement so as to reduce stress and burnout. As such, policy makers and hospital management may want to focus on setting clear mental health targets and facilitate manageable clinical workload, build manpower resiliency, optimize resources and provide flexible work arrangements to alleviate stress and burnout among MHP.

Impact of San Francisco’s New Street crisis response Team on Service use among people experiencing homelessness with mental and substance use disorders: A mixed methods study protocol

by Matthew L. Goldman, Megan McDaniel, Deepa Manjanatha, Monica L. Rose, Glenn-Milo Santos, Starley B. Shade, Ann A. Lazar, Janet J. Myers, Margaret A. Handley, Phillip O. Coffin

Mobile crisis services for people experiencing distress related to mental health or substance use are expanding rapidly across the US, yet there is little evidence to support these specific models of care. These new programs present a unique opportunity to expand the literature by utilizing implementation science methods to inform the future design of crisis systems. This mixed methods study will examine the effectiveness and acceptability of the Street Crisis Response Team (SCRT), a new 911-dispatched multidisciplinary mobile crisis intervention piloted in San Francisco, California. First, using quantitative data from electronic health records, we will conduct an interrupted time series analysis to quantitatively examine the impacts of the SCRT on people experiencing homelessness who utilized public behavioral health crisis services in San Francisco between November 2019 and August 2022, across four main outcomes within 30 days of the crisis episode: routine care utilization, crisis care reutilization, assessment for housing services, and jail entry. Second, to understand its impact on health equity, we will analyze racial and ethnic disparities in these outcomes prior to and after implementation of the SCRT. For the qualitative component, we will conduct semi-structured interviews with recipients of the SCRT’s services to understand their experiences of the intervention and to identify how the SCRT influenced their health-related trajectories after the crisis encounter. Once complete, the quantitative and qualitative findings will be further analyzed in tandem to assist with more nuanced understanding of the effectiveness of the SCRT program. This evaluation of a novel mobile crisis response program will advance the field, while also providing a model for how real-world program implementation can be achieved in crisis service settings.

Antibiofilm and antimicrobial activity of Lactobacillus cell free supernatant against Pseudomonas aeruginosa isolated from burn wounds

Abstract

The present study investigated the antimicrobial and anti-biofilm effects of indigenous Lactobacillus probiotic strains on Pseudomonas aeruginosa isolated from burn wound infection in laboratory conditions. The effect of 7 probiotic strains isolated from infant faeces on the pathogenicity factors of P. aeruginosa, including protease, elastase, antibiofilm and antipyocyanin was measured. Also, diffusion methods in the well and micro broth dilution were used to evaluate the antimicrobial activity of probiotics. All tests were performed in triplicate. A negative control and a positive control were used for each test. SPSS version 22 software was used for statistical analysis, and a p < 0.05 was considered statistically significant. A total of 30 clinical isolates of P. aeruginosa were isolated. The elastolytic activity of P. aeruginosa isolates decreased after adding Cell free supernatant (CFS) of each Lactobacillus. L1, L4, L5, and L6 strains had a 100% inhibitory effect on pathogen isolates. L3 and L7 strains had the lowest inhibitory effect. The inhibitory effect of CFS extracted from lactobacilli on protease production by P. aeruginosa. L1, L4, L5, and L6 strains had an inhibitory effect on all tested isolates. L2, L3, and L7 strains had a less inhibitory effect. L4 strain had the highest inhibitory effect on pyocyanin production by P. aeruginosa (50%), followed by L5 (43.3%), L1 (40%), and L6 (23.3%) strains. L3 and L7 strains had no inhibitory effect on the pyocyanin production of P. aeruginosa isolates. It was found that the CFS of 4 isolates (L1, L4, L5, and L6) was the most active extract and had a 100% inhibitory effect against biofilm formation of all P. aeruginosa strains. The L3 strain had the least inhibitory effect against the biofilm formation of pathogens. Overall, this study showed that probiotics could be promising alternatives to combat the pathogenicity of P. aeruginosa in burn wounds.

Two mouse models of Alzheimer’s disease accumulate amyloid at different rates and have distinct Aβ oligomer profiles unaltered by ablation of cellular prion protein

by Silvia A. Purro, Michael Farmer, Elizabeth Noble, Claire J. Sarell, Megan Powell, Daniel Yip, Lauren Giggins, Leila Zakka, David X. Thomas, Mark Farrow, Andrew J. Nicoll, Dominic Walsh, John Collinge

Oligomers formed from monomers of the amyloid β-protein (Aβ) are thought to be central to the pathogenesis of Alzheimer’s disease (AD). Unsurprisingly for a complex disease, current mouse models of AD fail to fully mimic the clinical disease in humans. Moreover, results obtained in a given mouse model are not always reproduced in a different model. Cellular prion protein (PrPC) is now an established receptor for Aβ oligomers. However, studies of the Aβ-PrPC interaction in different mouse models have yielded contradictory results. Here we performed a longitudinal study assessing a range of biochemical and histological features in the commonly used J20 and APP-PS1 mouse models. Our analysis demonstrated that PrPC ablation had no effect on amyloid accumulation or oligomer production. However, we found that APP-PS1 mice had higher levels of oligomers, that these could bind to recombinant PrPC, and were recognised by the OC antibody which distinguishes parallel, in register fibrils. On the other hand, J20 mice had a lower level of Aβ oligomers, which did not interact with PrPC when tested in vitro and were OC-negative. These results suggest the two mouse models produce diverse Aβ assemblies that could interact with different targets, highlighting the necessity to characterise the conformation of the Aβ oligomers concomitantly with the toxic cascade elicited by them. Our results provide an explanation for the apparent contradictory results found in APP-PS1 mice and the J20 mouse line in regards to Aβ toxicity mediated by PrPC.

Anethole attenuates motor dysfunctions, striatal neuronal activity deficiency and blood brain barrier permeability by decreasing striatal α-synuclein and oxidative stress in rotenone-induced Parkinson’s disease of male rats

by Sadegh Moradi Vastegani, Seyed Esmaeil Khoshnam, Samireh Ghafouri, Nima Bakhtiari, Yaghoob Farbood, Alireza Sarkaki

Introduction

Anethole is the main compound of the essential oil of anise and several other plants, which has antioxidant, anti-inflammatory, and neuroprotective properties. Oxidative stress is considered as an important factor in the pathogenesis of PD. In the present study, we aimed to investigate the effects of anethole against rotenone-induced PD.

Methods

Male Wistar rats were randomly divided into six groups. Control group received DMSO + sunflower oil, model group received rotenone (2 mg/kg, s.c, daily for 35 days), positive control group received L-Dopa, and test groups received anethole (62.5, 125, and 250 mg/kg, i.g, daily for 35 days) 1 hour before each rotenone injection. Body weight changes, rotarod test, stride length test, and extracellular single unit recording were performed after treatment. After behavioral test, Brain water content and blood brain barrier (BBB) permeability were evaluated, and the levels of malondialdehyde (MDA), superoxide dismutases (SOD), alpha-synuclein and MAO-B were measured in the striatum.

Results

Chronic administration of rotenone induced body weight loss and caused significant dysfunction in locomotor activity, neuronl firing rate, and BBB. Rotenone also decreased SOD activity, increased MDA level, and elevated the expression of alpha-synuclein and MAO-B in the striatum. However, treatment with anethole attenuated body weight loss, motor function, neuronal activity, and BBB function. Furthermore, Anethole treatment attenuated oxidative stress and decreased the expression of alpha-synuclein and MAO-B compared to the rotenone group.

Conclusion

Our results show that through its antioxidant properties, aethole can improve the cellular, molecular and behavioral characteristics of rotenone-induced Parkinson’s disease.

What are the perceptions and concerns of people living with diabetes and National Health Service staff around the potential implementation of AI-assisted screening for diabetic eye disease? Development and validation of a survey for use in a secondary car

Introduction

The English National Health Service (NHS) Diabetic Eye Screening Programme (DESP) performs around 2.3 million eye screening appointments annually, generating approximately 13 million retinal images that are graded by humans for the presence or severity of diabetic retinopathy. Previous research has shown that automated retinal image analysis systems, including artificial intelligence (AI), can identify images with no disease from those with diabetic retinopathy as safely and effectively as human graders, and could significantly reduce the workload for human graders. Some algorithms can also determine the level of severity of the retinopathy with similar performance to humans. There is a need to examine perceptions and concerns surrounding AI-assisted eye-screening among people living with diabetes and NHS staff, if AI was to be introduced into the DESP, to identify factors that may influence acceptance of this technology.

Methods and analysis

People living with diabetes and staff from the North East London (NEL) NHS DESP were invited to participate in two respective focus groups to codesign two online surveys exploring their perceptions and concerns around the potential introduction of AI-assisted screening.

Focus group participants were representative of the local population in terms of ages and ethnicity. Participants’ feedback was taken into consideration to update surveys which were circulated for further feedback. Surveys will be piloted at the NEL DESP and followed by semistructured interviews to assess accessibility, usability and to validate the surveys.

Validated surveys will be distributed by other NHS DESP sites, and also via patient groups on social media, relevant charities and the British Association of Retinal Screeners. Post-survey evaluative interviews will be undertaken among those who consent to participate in further research.

Ethics and dissemination

Ethical approval has been obtained by the NHS Research Ethics Committee (IRAS ID: 316631). Survey results will be shared and discussed with focus groups to facilitate preparation of findings for publication and to inform codesign of outreach activities to address concerns and perceptions identified.

Introduction

Care home residents have experienced significant morbidity, mortality and disruption following outbreaks of SARS-CoV-2. Regular SARS-CoV-2 testing of care home staff was introduced to reduce transmission of infection, but it is unclear whether this remains beneficial. This trial aims to investigate whether use of regular asymptomatic staff testing, alongside funding to reimburse sick pay for those who test positive and meet costs of employing agency staff, is a feasible and effective strategy to reduce COVID-19 impact in care homes.

Methods and analysis

The VIVALDI-Clinical Trial is a multicentre, open-label, cluster randomised controlled, phase III/IV superiority trial in up to 280 residential and/or nursing homes in England providing care to adults aged >65 years. All regular and agency staff will be enrolled, excepting those who opt out. Homes will be randomised to the intervention arm (twice weekly asymptomatic staff testing for SARS-CoV-2) or the control arm (current national testing guidance). Staff who test positive for SARS-CoV-2 will self-isolate and receive sick pay. Care providers will be reimbursed for costs associated with employing temporary staff to backfill for absence arising directly from the trial.

The trial will be delivered by a multidisciplinary research team through a series of five work packages.

The primary outcome is the incidence of COVID-19-related hospital admissions in residents. Secondary outcomes include the number and duration of outbreaks and home closures. Health economic and modelling analyses will investigate the cost-effectiveness and cost consequences of the testing intervention. A process evaluation using qualitative interviews will be conducted to understand intervention roll out and identify areas for optimisation to inform future intervention scale-up, should the testing approach prove effective and cost-effective. Stakeholder engagement will be undertaken to enable the sector to plan for results and their implications and to coproduce recommendations on the use of testing for policy-makers.

Ethics and dissemination

The study has been approved by the London—Bromley Research Ethics Committee (reference number 22/LO/0846) and the Health Research Authority (22/CAG/0165). The results of the trial will be disseminated regardless of the direction of effect. The publication of the results will comply with a trial-specific publication policy and will include submission to open access journals. A lay summary of the results will also be produced to disseminate the results to participants.

Introduction

Physical inactivity is a risk factor for repeat cardiac events and all-cause mortality in coronary heart disease (CHD). Cardiac rehabilitation, a secondary prevention programme, aims to increase physical activity levels in this population from a reported low baseline. This trial will investigate the effectiveness and implementation of a very brief physical activity intervention, comparing different frequencies of physical activity measurement by cardiac rehabilitation clinicians. The Measure It! intervention (

Vignettes as a novel research tool in spiritual care: A methods paper

Abstract

Aims

To discuss the construction and use of vignettes as a novel approach in spiritual care research and education.

Design

Methods paper.

Methods

In this methods paper, the authors introduce the use of vignettes in spiritual care research and provide insight into the construction of vignettes. The vignette presented was part of a study of neurosurgical nurses' attitudes and responses to the spiritual needs of neuro-oncology patients. The development process, consisting of four steps, is explained in this paper.

Results

Using a vignette to explore nurses' attitudes towards spiritual care is an innovative way to understand what behaviours nurses consider appropriate in situations where the patient is seeking meaning and connection. Transparent description of the development process is crucial to ensure reproducibility.

Conclusion

The use of theoretically constructed and validated vignettes in spiritual care research is new. Vignettes used in surveys have the potential to elicit nurses' responses to patients' search for meaning and connectedness.

Implications

In order to investigate nurses' attitudes and behaviours towards patients' spiritual needs, carefully constructed and validated vignettes are valuable research tools.

Impact

Vignettes have proven to be a valuable research tool in the social and health sciences. So far, their use as a survey instrument in spiritual care research has not been investigated. Therefore, this method paper introduces vignettes as a novel approach to spiritual care research. Our findings contribute to the further development of vignettes in nursing science, as there are similarities with case development and simulation training in nursing education.

Reporting Method

Reporting guideline is not applicable.
