Using a novel methodology to map Post-COVID services for children and young people in England: a web-based systematic search

BackgroundPost-COVID Condition (PCC), also known as ‘Long COVID,’ refers to persistent symptoms following a coronavirus 2 (SARS-CoV-2) infection. The prevalence of PCC in children and adolescents varies, impacting multiple body systems and affecting daily functioning. Specialised paediatric hubs were established in England to address the needs of young individuals with PCC. Additional local services also emerged, yet patients report challenges accessing services. To better understand the landscape of paediatric PCC services, we used a novel methodology using a web-based systematic search.MethodsA web-based search was conducted in July 2023 using DEVONagent Pro. Search terms related to Long COVID and Pediatrics in England. Eligible sources providing information on PCC services for children and young people were included. A supplementary manual search and NHS England Post-COVID Network were also consulted. Data extraction included service location, characteristics, and referral pathways. Population estimates were derived from UK Census data.ResultsAmong 342 identified records, 27 services met eligibility criteria, distributed unevenly across regions. Specialised hubs covered 13 locations, while additional services were concentrated in the South of England and London. Services varied in team composition, age range treated, and support offered. A lack of standardised approaches for paediatric PCC was evident.DiscussionWe used a novel methodology for systematically mapping online resources, providing valuable insights into service accessibility and aiding the identification of potential gaps. We observed geographical disparities in access to paediatric PCC services and the absence of standardised approaches in managing symptoms. Given the challenges faced by young individuals seeking support for their PCC the need for equitable and standardised care became apparent. The study contributes to closing the research-practice gap and calls for further research to identify effective treatments for paediatric PCC, acknowledging the diversity of reported symptoms and the importance of tailored approaches.

The Use of Online Consultation Systems and Patient Experience of Primary Care: Cross-Sectional Analysis Using the General Practice Patient Survey.

NHS England encourages the use of online consultation (OC) systems alongside traditional access methods for patients to contact their general practice online and for practices to manage workflow. Access is a key driver of patients' primary care experience. The use of online technology and patient experience vary by sociodemographic characteristics. This study aims to assess the association between OC system use and patient experience of primary care in English general practice and how that varies by OC system model and practice sociodemographic characteristics (rurality, deprivation, age, and ethnicity). We categorized practices as "low-use" or "high-use" according to the volume of patient-initiated contacts made via the OC system. We considered practices using one of 2 OC systems with distinct designs and implementation models-shorter "free text" input with an embedded single workflow OC system (FT practices) and longer "mixed text" input with variation in implemented workflow OC system (MT practices). We used 2022 General Practice Patient Survey data to capture 4 dimensions of patient experience-overall experience, experience of making an appointment, continuity of care, and use of self-care before making an appointment. We used logistic regression at the practice level to explore the association between OC system use and patient experience, including interaction terms to assess sociodemographic variation. We included 287,194 responses from 2423 MT and 170 FT practices. The proportions of patients reporting positive experiences at MT and FT practices were similar or better than practices nationally, except at high-use MT practices. At high-use MT practices, patients were 19.8% (odds ratio [OR] 0.802, 95% CI 0.782-0.823) less likely to report a good overall experience; 24.5% (OR 0.755, 95% CI 0.738-0.773) less likely to report a good experience of making an appointment; and 18.9% (OR 0.811, 95% CI 0.792-0.83) less likely to see their preferred general practitioner; but 27.8% (OR 1.278, 95% CI 1.249-1.308) more likely to use self-care, compared with low-use MT practices. Opposite trends were seen at FT practices. Sociodemographic inequalities in patient experience were generally lower at high-use than low-use practices; for example, gaps in overall experience between practices with the most and fewest White patients decreased by 2.7 percentage points at MT practices and 6.4 percentage points at FT practices. Trends suggested greater improvements in experience for traditionally underserved groups-patients from urban and deprived areas, younger patients, and non-White patients. An OC system with shorter free text input and an integrated single workflow can enhance patient experience and reduce sociodemographic inequalities. Variation in patient experience between practices with different sociodemographic characteristics and OC systems underscores the importance of tailored design and implementation. Generalizing results across different OC systems is difficult due to variations in how they are integrated into practice workflows and communicated to patients.

Service Users' Experiences of a Nationwide Digital Type 2 Diabetes Self-Management Intervention (Healthy Living): Qualitative Interview Study.

Diabetes Self-Management Education and Support programs for people living with type 2 diabetes mellitus (T2DM) can increase glycemic control and reduce the risk of developing T2DM-related complications. However, the recorded uptake of these programs is low. Digital self-management interventions have the potential to overcome barriers associated with attendance at face-to-face sessions. Healthy Living is an evidence-based digital self-management intervention for people living with T2DM, based on the Healthy Living for People with Type 2 Diabetes (HeLP-Diabetes) intervention, which demonstrated effectiveness in a randomized controlled trial. NHS England has commissioned Healthy Living for national rollout into routine care. Healthy Living consists of web-based structured education and Tools components to help service users self-manage their condition, including setting goals. However, key changes were implemented during the national rollout that contrasted with the trial, including a lack of facilitated access from a health care professional and the omission of a moderated online support forum. This qualitative study aims to explore service users' experiences of using Healthy Living early in the national rollout. A total of 19 participants were interviewed via telephone or a videoconferencing platform. Topics included users' experiences and views of website components, their understanding of the intervention content, and the overall acceptability of Healthy Living. Transcripts were analyzed thematically using a framework approach. Participants valued having trustworthy information that was easily accessible. The emotional management content resonated with the participants, prompting some to book an appointment with their general practitioners to discuss low mood. After completing the structured education, participants might have been encouraged to continue using the website if there was more interactivity (1) between the website and other resources and devices they were using for self-management, (2) with health professionals and services, and (3) with other people living with T2DM. There was consensus that the website was particularly useful for people who had been newly diagnosed with T2DM. Digital Diabetes Self-Management Education and Support programs offering emotional aspects of self-management are addressing an unmet need. Primary care practices could consider offering Healthy Living to people as soon as they are diagnosed with T2DM. Participants suggested ways in which Healthy Living could increase interaction with the website to promote continued long-term use.

The safety of antivirals and neutralising monoclonal antibodies used in prehospital treatment of Covid-19

ObjectiveThis proof-of-principle pharmacovigilance study used Electronic Health Record (EHR) data to examine the safety of sotrovimab, paxlovid and molnupiravir in prehospital treatment of Covid-19. MethodWith NHS England approval, we conducted an observational cohort study using OpenSAFELY-TPP, a secure software-platform which executes analyses across EHRs for 24 million people in England. High-risk individuals with Covid-19 eligible for prehospital treatment were included. Adverse events (AEs) were categorised into events in the drug’s Summary of Product Characteristics (SmPC), drug-reactions and immune-mediated. Cox models compared risk across treatments. A pre-pandemic record analysis was performed for comparative purposes. ResultsBetween 2021-2023, 37,449 patients received sotrovimab, paxlovid or molnupiravir whilst 109,647 patients made up an eligible-but-untreated population. The 29-day rates of AEs were low: SmPC 0.34 per 1000 patient-years (95%CI 0.32-0.36); drug-reactions 0.01(95% CI0.01-0.02) and immune-mediated 0.03(95%CI 0.03-0.04), and similar or lower than the pre-pandemic period. Compared with the eligible but untreated population, sotrovimab and paxlovid associated with a risk of SmPC AE [adjHR 1.36(95%CI 1.15-1.62) and 1.28(95%CI 1.05-1.55), respectively], whilst sotrovimab associated with a risk of drug-reactions [adjHR 2.95(95%CI 1.56-5.55)] and immune-mediated events [adjHR 3.22(95%CI 1.86-5.57)]. ConclusionSotrovimab, paxlovid and molnupiravir demonstrate acceptable safety profiles. Although the risk of AEs was greatest with sotrovimab, event rates were lower than comparative pre-pandemic period.

Systematic review and narrative synthesis of the experiences of individuals with chronic pain participating in digital pain management interventions.

The use of digital pain management interventions has grown since the Covid 19 pandemic. The aim of this study was to systematically review and synthesise evidence from qualitative studies regarding the experiences of individuals with chronic pain participating in digital pain management interventions in primary care and community settings. Fourteen databases were searched, as well as citation tracking and hand-searching reference lists of included articles. The latest search was completed by 07/07/2023. Qualitative studies of patient and carer perspectives of digital pain management interventions for adults aged 18 and over with non-malignant chronic pain were included. All studies were appraised for quality using the Critical Appraisal Skills Programme Qualitative Checklist. A narrative synthesis approach was used to synthesise the findings. Normalisation Process Theory was used to understand how individuals with chronic pain make sense of digital pain management interventions and incorporate knowledge, skills and strategies learnt into their day-to-day lives. Eleven studies, encompassing both digital applications for use on smartphones/ mobile devices and user-directed online modular programmes, were included in the synthesis. Three main themes and related subthemes were identified from the included studies: 1) Making sense of the digital intervention (Subthemes: Tailoring to user's needs; Human contact and support; Accessibility of the digital intervention; Personal and environmental factors affecting engagement with digital interventions); 2) Initiating and Maintaining Behaviour Change (Subthemes: Planning activity; Being active); and 3) Personal Growth (Subthemes: Gaining understanding and skills; Gaining and acting on feedback; Negotiating a new relationship with pain). Recommendations. The key recommendations from our findings are that digital pain management interventions should provide: Specific and tailored information for individual participants.Focus on changing attitudes and behaviours and reframing perceptions of pain.Structured goal setting with prompts to review goals.Potential healthcare professional support alongside the digital intervention.Limitations of the review. To reduce bias, it would have been preferable for more than one author to independently fully analyse each paper and to identify themes and sub-themes. Instead, the identified themes and sub-themes were discussed with two other authors in the team (ES, LW) to reach a consensus view on final themes and sub-themes. One author (JS) received a Research Internship and Research Initiation Award funded by NIHR Applied Research Collaboration (ARC) Wessex (https://www.arc-wx.nihr.ac.uk/) and NHS England (https://www.england.nhs.uk/). The protocol for this review was registered with the National Institute of Health Research (NIHR) PROSPERO international database for registering systematic reviews (PROSPERO Registration Number CRD42021257768).

Women’s engagement with community perinatal mental health services: a realist evaluation

BackgroundIn recognition of the burden of Perinatal Mental Health problems, NHS England invested £365 million to transform women’s access to mental health care, including investment in Community Perinatal Mental Health Services. This study examined how elements of provider care affected women’s engagement with these services.MethodsSemi-structured interviews were conducted with 139 women and explored their experiences of care from 10 different Community Perinatal Mental Health Teams; including which service components participants believed made a difference to their initial and continued engagement. Realist analysis was used to create context-mechanism-outcome configurations (CMOCs) across interviews, since not all parts of the configurations were always articulated within singular interviews.ResultsFour key pillars for engagement were identified: perinatal competence, relationship building, accurate reassurance, and reliability. The way perinatal competencies were relayed to women mattered; compassion, understanding and consistency were critical interactional styles. The extent to which these factors affected women’s engagement varied by their context and personal characteristics.ConclusionsAs mental health problems increase, disproportionately affecting vulnerable populations, it is critical to continue to ensure support is not only available, but appropriately meets the needs of those individuals. Our findings suggest that key staff behaviours applied at the right time can support women’s engagement and potentially contribute to better treatment outcomes.

662 A Sustainable Laparoscopic Cholecystectomy Tray

Abstract Aim The aim was to develop and trial a systematic methodology in order to streamline laparoscopic cholecystectomy trays across all sub-specialties in Leeds Teaching Hospitals Trust (LTHT), and to inform rationalisation principles nationally in partnership with NHS England’s sustainability team. Method 70 laparoscopic cholecystectomies across all sub-specialties were independently observed and audited for instrument usage at LTHT from January to March 2023. The findings were summarised and a usage heatmap was developed. A subsequent ‘hackathon’ event was held in the form of a consensus session with key stakeholders from each sub-specialty to agree a proposed single instrument tray. Carbon and financial savings calculations were then undertaken to measure the impact of the changes. Results Audit results demonstrated an average of 112 instruments across four separate trays opened. The heat map demonstrated 42% of items were used from 0-5% of procedures. The hackathon event agreed a consolidated single tray of 65 items. With over 800 laparoscopic cholecystectomies taking place in LTHT per year predicted financial savings in sterilisation costs were over £22,000 and over 3 tonnes of CO2e annually. Conclusions Tray rationalisation and standardisation has significant financial and carbon savings and can be extrapolated to many types of procedures. Sustainable change is vital to meet NHS net zero targets and requires urgent attention. Stakeholder engagement was crucial to ensure changes were agreeable and would be sustained. Following the successfully trialled methodology and implementation NHS England have produced a guide for other trusts to implement similar changes.

Supporting advanced practice: feedback from a mental health, community and primary care advanced practice support project in South Yorkshire, UK

Background: Despite the significant input from Heath Education England (HEE), now NHS England (NHSE), there are still significant variations around advanced practice programmes, support and training, particularly in less developed areas such as mental health, community posts and primary care. To help target these areas, and to support the NHS Long Term Plan (2023) to increase the number of advanced clinical practitioners (ACPs), the Faculty of Advanced Practice South Yorkshire recruited three ACP leads from mental health, community, and primary care backgrounds to establish a support project led by one professional lead. These leads were able to utilise their lived experience of completing the ACP MSc programme and working as an ACP to help trainee advanced clinical practitioners (tACPs) navigate their journey. The ACP leads also developed a variety of educational events, which further supported the trainees' needs. Aim: This article reports the feedback given via an online questionnaire from trainees that accessed the project, which ended in March 2024. Its aim is to highlight the often-undervalued concept of using clinicians personal experience regarding advanced training and practice, to mentor, support and ultimately retain the future ACP workforce. Methods: An email with a link to a questionnaire was sent to 128 tACPs or recently qualified ACPs that had applied for their training via the Faculty of Advanced Practice South Yorkshire. The questionnaire, created in Microsoft Forms, was completed anonymously, and produced both numerical and free-text data. The questionnaire solicited feedback around: the number of contacts they had and how they contacted; the ACP leads; types of support accessed; and the educational events available. Free text answers were analysed by the author (CJ) and a second reviewer (SF) to generate a consensus on themes. Results: A total of 64 clinicians responded, of which 43 were tACPs, 10 were ACPs, five had other job titles (community matron, pharmacist, practice nurse) and five did not state what their job title was. Responses suggest that the support accessed from the project was highly beneficial and could not be gained elsewhere. A key factor in the project's success was the ACP leads' lived experience of having previously completed advanced practice training, as well as their ability to tailor learning events to the trainees' needs. Conclusion: Meeting the demands of ACP training in areas where the role is less established remains an ongoing challenge. It seems some of these challenges relate to the lack of practical support being provided by employers or higher education institutions, such as lived experience of completing the task of ACP training. Support projects, like the one discussed in this article, appear aptly placed to help fulfil these needs and begs the question ‘why aren't there more?’, especially when advanced practitioners are fundamental to the future healthcare workforce.

Interpreting pathology test result values with comparators (< , >) in Electronic Health Records research: an OpenSAFELY short data report

Background Numeric results of pathology tests are sometimes returned as a range rather than a precise value, e.g. “<10”. In health data research, test result values above or below clinical threshold values are often used to categorise patients into groups; however comparators (<, > etc) are typically stored separately to the numeric values and often ignored, but may influence interpretation. Methods With the approval of NHS England we used routine clinical data from 24 million patients in OpenSAFELY to identify pathology tests with comparators commonly attached to result values. For each test we report: the proportion returned with comparators present, split by comparator type and geographic region; the specific numeric result values returned with comparators, and the associated reference limits. Results We identified 11 common test codes where at least one in four results had comparators. Three codes related to glomerular filtration rate (GFR) tests/calculations, with 31-45% of results returned with “≥” comparators. At least 90% of tests with numeric values 60 and 90 represented ranges (≥60 and ≥90 respectively) rather than exact values. The other tests - four blood tests (Nucleated red blood cell count, Plasma C reactive protein, Tissue transglutaminase immunoglobulin A, and Rheumatoid factor), two urine tests (albumin/microalbumin) and two faecal tests (calprotectin and quantitative faecal immunochemical test) - were returned with “≤” comparators (29-86%). Conclusions Comparators appear commonly in certain pathology tests in electronic health records. For most common affected tests, we expect there to be minimal implications for researchers for most use-cases. However, care should be taken around whether results falling exactly on clinical threshold values should be considered “normal” or “abnormal”. Results from GFR tests/calculations cannot reliably distinguish between mild kidney disease (stage G2, 60-<90) versus healthy kidney function (90+). More broadly, health data researchers using numeric test result values should consider the impact of comparators.

Risk of emergency hospital admission related to adverse events after antibiotic treatment in adults with a common infection: impact of COVID-19 and derivation and validation of risk prediction models

BackgroundWith the global challenge of antimicrobial resistance intensified during the COVID-19 pandemic, evaluating adverse events (AEs) post-antibiotic treatment for common infections is crucial. This study aims to examines the changes in incidence rates of AEs during the COVID-19 pandemic and predict AE risk following antibiotic prescriptions for common infections, considering their previous antibiotic exposure and other long-term clinical conditions.MethodsWith the approval of NHS England, we used OpenSAFELY platform and analysed electronic health records from patients aged 18–110, prescribed antibiotics for urinary tract infection (UTI), lower respiratory tract infections (LRTI), upper respiratory tract infections (URTI), sinusitis, otitis externa, and otitis media between January 2019 and June 2023. We evaluated the temporal trends in the incidence rate of AEs for each infection, analysing monthly changes over time. The survival probability of emergency AE hospitalisation was estimated in each COVID-19 period (period 1: 1 January 2019 to 25 March 2020, period 2: 26 March 2020 to 8 March 2021, period 3: 9 March 2021 to 30 June 2023) using the Kaplan–Meier approach. Prognostic models, using Cox proportional hazards regression, were developed and validated to predict AE risk within 30 days post-prescription using the records in Period 1.ResultsOut of 9.4 million patients who received antibiotics, 0.6% of UTI, 0.3% of URTI, and 0.5% of LRTI patients experienced AEs. UTI and LRTI patients demonstrated a higher risk of AEs, with a noted increase in AE incidence during the COVID-19 pandemic. Higher comorbidity and recent antibiotic use emerged as significant AE predictors. The developed models exhibited good calibration and discrimination, especially for UTIs and LRTIs, with a C-statistic above 0.70.ConclusionsThe study reveals a variable incidence of AEs post-antibiotic treatment for common infections, with UTI and LRTI patients facing higher risks. AE risks varied between infections and COVID-19 periods. These findings underscore the necessity for cautious antibiotic prescribing and call for further exploration into the intricate dynamics between antibiotic use, AEs, and the pandemic.

Widening access to older people’s clinical psychology: Piloting a summer shadowing programme in older adults services

Within recent years, there has been an expansion of UK clinical psychology courses, additional psychological professions and increased attention to psychological wellbeing as part of the NHS Long Term Plan (NHS England, 2019). It has been an energetic time for clinical psychology and in turn, older adult clinical psychology. However, despite the expansion of training places, pervasive social inequalities have meant that for some a career in clinical psychology is less accessible, meaning that the psychology workforce is less diverse. This, in combination with lack of parity in investment for Older Adult Services, can mean older adults’ access to more representative psychological professionals remain hindered. The current paper explores a recent shadowing programme that our small psychology team and older adults’ mental health team piloted in the summer of 2023. Eight female students were able to complete the programme and provided insightful feedback on the experience. We reflect on future learnings and recommendations of setting up such projects in older adult services.

Early intervention for children and young people with neurodevelopmental conditions and intellectual disability: “The Getting Help” offer for Northwest England

Purpose The purpose of this paper is to outline what early support should be offered to children and young people with neurodevelopmental conditions including those who are autistic or have intellectual disability. A review of all child and adolescent mental health services (CAMHS) services in the Northwest completed by NHS England and Improvement (Doyle and Ryan, 2021) found that there was no clear Tier 2 offer (for mild to moderate mental health issues) for autistic children and young people or for those with intellectual disability. Following this review, a project group that had developed a model for mental health services for autistic children and young people and for those with intellectual disability (Wee et al., 2021) was tasked with articulating the “Getting Help” offer for children and young people with neurodevelopmental conditions, including intellectual disability. Design/methodology/approach A working group was created consisting of professionals from mental health, education and local authority and lived experience representatives of coproduction partners. A brief review of the background literature was also conducted. Six meetings were held to create a framework for the “Getting Help” offer and to discuss what the offer should be based on professional expertise and lived experience. Findings Recommendations for the Getting Help multi-agency offer included pre- and post-assessment support as part of a single attention deficit hyperactivity disorder/autism/neurodevelopmental pathway, community support for children with intellectual disability, access to adapted mental health support and the need for early recognition and support for avoidant and restrictive food intake disorder. Key themes from working group discussions included the reduction in the quality of services experienced by children and families due to silo working, which increased the risk of falling between multi-agency services and led to early signs of neurodevelopmental needs, or mental health issues being missed. Another theme was aiming for equity of access and outcomes. Originality/value This work is a response to a coproduced review of CAMHS in the Northwest and incorporates the lived experience of young people and families. It also adopts a holistic multi-agency neurodevelopmental approach rather than focusing on a single diagnosis or service.

The Impact of the Covid-19 Pandemic on an Integrated Care Programme for Older People with Different Frailty Levels (OPDFL): A Qualitative Study with Service Providers in the East of England.

While populations of all ages were affected by the pandemic, older people with frailty had much worse outcomes. The NHS England has mandated identifying and proactively managing older people with moderate and severe frailty in the General medical services (GMS) contract 2017/18. As a result of this policy, an integrated care programme for older people with different frailty levels (OPDFL) was introduced in Luton in 2018 (known as, Luton Framework for Frailty - LFF). This study was conducted to explore the views of service providers in Luton regarding the impact of the COVID-19 pandemic on the implementation of LFF. Semi-structured interviews were conducted with service providers in Luton between April 2021 to July 2021. The data were analysed using thematic analysis. Eighteen service providers took part in the study. Three main themes were identified, the first of which was that proactive and frailty-related health promotion services were halted. Secondly, existing relationships due to the LFF facilitated the implementation of services for care home residents during the pandemic. Finally, participants identified that some of the challenges impacting the delivery of health promotion services were those that affected the health system in general, such as healthcare staff feeling stressed and the centralised decision-making by the government. The lessons learnt from this study could be useful in managing services for older people with frailty in times of emergencies or epidemics.

A Cost Evaluation of COVID-19 Remote Home Monitoring Services in England.

Remote home monitoring services emerged as critical components of health care delivery from NHS England during the COVID-19 pandemic, aiming to provide timely interventions and reduce health care system burden. Two types of service were offered: referral by community health services to home-based care to ensure the right people were admitted to the hospital at the right time (called COVID Oximetry@home, CO@h); and referral by hospital to support patients' transition from hospital to home (called COVID-19 Virtual Ward, CVW). The information collected for the oxygen levels and other symptoms was provided via digital means (technology-enabled) or over the phone (analogue-only submission mode). This study aimed to evaluate the costs of implementing remote home monitoring for COVID-19 patients across 26 sites in England during wave 2 of the pandemic. Understanding the operational and financial implications of these services from the NHS perspective is essential for effective resource allocation and service planning. We used a bottom-up costing approach at the intervention level to describe the costs of setting up and running the services. Twenty-six implementation sites reported the numbers of patients and staff involved in the service and other resources used. Descriptive statistics and multivariable regression analysis were used to assess cost variations and quantify the relationship between the number of users and costs while adjusting for other service characteristics. The mean cost per patient monitored was lower in the CO@h service compared with the CVW service (£527 vs £599). The mean cost per patient was lower for implementation sites using technology-enabled and analogue data submission modes compared with implementation sites using analogue-only modes for both CO@h (£515 vs £561) and CVW (£584 vs £612) services. The number of patients enrolled in the services and the service type significantly affected the mean cost per patient. Our analysis provides a framework for evaluating the costs of similar services in the future and shows that the implementation of these services benefit from the employment of tech-enabled data submission modes.

Changes in sick notes associated with COVID-19 from 2020 to 2022: a cohort study in 24 million primary care patients in OpenSAFELY-TPP

ObjectivesLong-term sickness absence from employment has negative consequences for the economy and can lead to widened health inequalities. Sick notes (also called ‘fit notes’) are issued by general practitioners when...

Demonstrating the data integrity of routinely collected healthcare systems data for clinical trials (DEDICaTe): A proof-of-concept study.

Introduction/aims: Healthcare systems data (also known as real-world or routinely collected health data) could transform the conduct of clinical trials. Demonstrating integrity and provenance of these data is critical for clinical trials, to enable their use where appropriate and avoid duplication using scarce trial resources. Building on previous work, this proof-of-concept study used a data intelligence tool, the "Central Metastore," to provide metadata and lineage information of nationally held data. Methods: The feasibility of NHS England's Central Metastore to capture detailed records of the origins, processes, and methods that produce four datasets was assessed. These were England's Hospital Episode Statistics (Admitted Patient Care, Outpatients, Critical Care) and the Civil Registration of Deaths (England and Wales). The process comprised: information gathering; information ingestion using the tool; and auto-generation of lineage diagrams/content to show data integrity. A guidance document to standardise this process was developed. Results/Discussion: The tool can ingest, store and display data provenance in sufficient detail to support trust and transparency in using these datasets for trials. The slowest step was information gathering from multiple sources, so consistency in record-keeping is essential.

Dementia diagnosis rates and the impact of ethnicity, rurality and deprivation

Objectives NHS England publishes monthly national and regional estimated dementia diagnosis rates (DDR) to assess the healthcare system’s effectiveness in identifying dementia cases. Previous research indicates that sociodemographic factors, such as ethnic minority status, socioeconomic deprivation, and rurality, influence both healthcare quality and dementia risk. This study aimed to examine the association between these sociodemographic factors and DDR, and to estimate an ethnicity-adjusted DDR using available ethnic group data. Method We analysed NHS Digital Primary Care Dementia Data electronic health records for July 2023. We used a linear regression model to determine the association between DDR and ethnicity, deprivation, and rurality factors using local authority region level data. We also adjusted the DDR at the level of sub-integrated care boards based on previously published odds ratios of dementia diagnosis by ethnic group. Results Regression modelling revealed that areas with higher proportions of minority ethnic groups and greater rurality had lower DDRs. Conversely, higher levels of deprivation were linked to higher DDRs. After adjusting for different odds ratios for dementia in minority ethnic groups, the national DDR decreased by 1%, with regional diagnosis rates dropping by up to 5.4%. Conclusion Higher regional proportional ethnic minority population and greater rurality were associated with a lower DDR which might reflect poorer access to diagnostic services. Higher deprivation levels were associated with a higher DDR which might reflect higher rates of dementia in more deprived populations. We discuss measures to improve the accuracy and utility of the DDR, with a specific focus on ethnicity.

Vaccinations, cardiovascular drugs, hospitalization, and mortality in COVID-19 and Long COVID

ObjectiveTo identify highest-risk subgroups for COVID-19 and Long COVID(LC), particularly in contexts of influenza and cardiovascular disease(CVD). MethodsUsing national, linked electronic health records for England (NHS England Secure Data Environment via CVD-COVID-UK/COVID-IMPACT Consortium), we studied individuals (of all ages) with COVID-19 and LC (2020-2023). We compared all-cause hospitalization and mortality by prior CVD, high CV risk, vaccination status (COVID-19/influenza), and CVD drugs, investigating impact of vaccination and CVD prevention using population preventable fractions. ResultsHospitalization and mortality were 15.3% and 2.0% among 17,373,850 individuals with COVID-19 (LC rate 1.3%), and 16.8% and 1.4% among 301,115 with LC. Adjusted risk of mortality and hospitalization were reduced with COVID-19 vaccination ≥ 2 doses(COVID-19:HR 0.36 and 0.69; LC:0.44 and 0.90). With influenza vaccination, mortality was reduced, but not hospitalization (COVID-19:0.86 and 1.01, and LC:0.72 and 1.05). Mortality and hospitalization were reduced by CVD prevention in those with CVD, e.g., anticoagulants- COVID:19:0.69 and 0.92; LC:0.59 and 0.88; lipid lowering- COVID-19:0.69 and 0.86; LC:0.68 and 0.90. COVID-19 vaccination averted 245044 of 321383 and 7586 of 8738 preventable deaths after COVID-19 and LC, respectively. InterpretationPrior CVD and high CV risk are associated with increased hospitalization and mortality in COVID-19 and LC. Targeted COVID-19 vaccination and CVD prevention are priority interventions.

Trends in weight gain recorded in English primary care before and during the Coronavirus-19 pandemic: An observational cohort study using the OpenSAFELY platform.

Obesity and rapid weight gain are established risk factors for noncommunicable diseases and have emerged as independent risk factors for severe disease following Coronavirus Disease 2019 (COVID-19) infection. Restrictions imposed to reduce COVID-19 transmission resulted in profound societal changes that impacted many health behaviours, including physical activity and nutrition, associated with rate of weight gain. We investigated which clinical and sociodemographic characteristics were associated with rapid weight gain and the greatest acceleration in rate of weight gain during the pandemic among adults registered with an English National Health Service (NHS) general practitioner (GP) during the COVID-19 pandemic. With the approval of NHS England, we used the OpenSAFELY platform inside TPP to conduct an observational cohort study of routinely collected electronic healthcare records. We investigated changes in body mass index (BMI) values recorded in English primary care between March 2015 and March 2022. We extracted data on 17,742,365 adults aged 18 to 90 years old (50.1% female, 76.1% white British) registered with an English primary care practice. We estimated individual rates of weight gain before (δ-prepandemic) and during (δ-pandemic) the pandemic and identified individuals with rapid weight gain (>0.5 kg/m2/year) in each period. We also estimated the change in rate of weight gain between the prepandemic and pandemic period (δ-change = δ-pandemic-δ-prepandemic) and defined extreme accelerators as the 10% of individuals with the greatest increase in their rate of weight gain (δ-change ≥1.84 kg/m2/year) between these periods. We estimated associations with these outcomes using multivariable logistic regression adjusted for age, sex, index of multiple deprivation (IMD), and ethnicity. P-values were generated in regression models. The median BMI of our study population was 27.8 kg/m2, interquartile range (IQR) [24.3, 32.1] in 2019 (March 2019 to February 2020) and 28.0 kg/m2, IQR [24.4, 32.6] in 2021. Rapid pandemic weight gain was associated with sex, age, and IMD. Male sex (male versus female: adjusted odds ratio (aOR) 0.76, 95% confidence interval (95% CI) [0.76, 0.76], p < 0.001), older age (e.g., 50 to 59 years versus 18 to 29 years: aOR 0.60, 95% CI [0.60, 0.61], p < 0.001]); and living in less deprived areas (least-deprived-IMD-quintile versus most-deprived: aOR 0.77, 95% CI [0.77, 0.78] p < 0.001) reduced the odds of rapid weight gain. Compared to white British individuals, all other ethnicities had lower odds of rapid pandemic weight gain (e.g., Indian versus white British: aOR 0.69, 95% CI [0.68, 0.70], p < 0.001). Long-term conditions (LTCs) increased the odds, with mental health conditions having the greatest effect (e.g., depression (aOR 1.18, 95% CI [1.17, 1.18], p < 0.001)). Similar characteristics increased odds of extreme acceleration in the rate of weight gain between the prepandemic and pandemic periods. However, changes in healthcare activity during the pandemic may have introduced new bias to the data. We found female sex, younger age, deprivation, white British ethnicity, and mental health conditions were associated with rapid pandemic weight gain and extreme acceleration in rate of weight gain between the prepandemic and pandemic periods. Our findings highlight the need to incorporate sociodemographic, physical, and mental health characteristics when formulating research, policies, and interventions targeting BMI in the period of post pandemic service restoration and in future pandemic planning.
