Background Post-infection conditions (PICs), such as Long Covid, are associated with heterogeneous, fluctuating symptoms that profoundly affect daily functioning. Despite moderate-certainty evidence from the NIHR-funded LISTEN trial (COV-LT2-0009) that personalised self management support improves outcomes and may reduce societal and economic impacts of Long Covid, many people living with PICs still receive condition-specific services, generic advice, or stand-alone digital tools that do not address their complex needs. Aim To map care approaches in general practice and synthesise UK evidence for PIC management. Design and setting Scoping review and online survey. Method A two-phase study was conducted: (1) a scoping review of UK evidence on PIC management in general practice; and (2) a supplementary online survey of practitioners working in UK general practice to provide contextual insights. Results The scoping review identified 32 studies focused on Long Covid. One study included a comparator group (ME/CFS). Study populations were predominantly white ethnicity and female. Evidence for non-Covid PICs in UK general practice was largely absent. The supplementary survey (n=46) provided preliminary practice-level insights. Healthcare practitioners reported varied PIC presentations, diagnostic uncertainty, limited referral pathways, inequitable access, and low confidence in managing PICs. Conclusion Evidence informing PIC management in UK general practice remains predominantly Long Covid-focused and may not reflect the range of PICs encountered in practice. While survey findings are preliminary and require confirmation in larger samples, they highlight uncertainty around PIC management. Further research is needed to evaluate whether existing Long Covid pathways should be expanded or complemented by broader PIC models.

BACKGROUND Safe and effective antidepressant deprescribing strategies are needed in general practice where most antidepressant prescribing occurs. METHODS We conducted a pragmatic, cluster-randomised controlled trial in general practice to test invitation to general practitioner (GP) review combined with resources to inform shared decision-making and guide hyperbolic tapering for stopping antidepressants compared to usual care. Adults taking antidepressants for longer than 12 months were recruited from 26 Australian GP practices between March 2023 and November 2024, irrespective of their intention to stop or depression or anxiety symptom scores. The primary outcome was cessation at 12 months. Secondary outcomes included cessation at 6 months, and >75% dose reduction and depression, anxiety and withdrawal symptom scores at 6 and 12 months. RESULTS Overall, 483 patients were randomised. Mean age was 50 years; 73% were women; mean duration of antidepressant use was 14.1 years. Cessation at 12 months was observed in 32 of 215 (14.9%) intervention and 16 of 187 (8.6%) usual care patients (odds ratio (OR) = 1.95 [95%CI, 1.00 to 3.81]; p=0.050). Cessation at 6 months was observed in 11.7% intervention vs 4.8% usual care (OR = 2.68; 95%CI, 1.18 to 6.05), and >75% dose reduction at 12 months in 19.6% intervention vs 9.9% usual care (OR = 2.28; 95%CI, 1.20 to 4.31). Symptom scores were similar between groups. No adverse events were attributable to the intervention. CONCLUSIONS In general practice, invitation to GP antidepressant review combined with information and guidance on hyperbolic tapering can support cessation or dose reduction without causing adverse effects or relapse. Absolute cessation rates were modest but still meaningful given the high prevalence of long term antidepressant use. TRIAL REGISTRATION ANZCT registry identifier, ACTRN12622001379707p.

Background Effective communication during consultations is facilitated by clinical empathy and realistic optimism, and can enhance patient satisfaction with care, alleviate symptoms, and improve quality of life. However, primary care systems are under significant strain and changing rapidly, which may affect practitioners' ability to communicate empathically and convey realistic optimism, with implications for the patient-practitioner relationship and patient outcomes. Understanding patients' perspectives of healthcare communication in the current clinical context is therefore important. We aimed to explore patients' experiences and perceptions of communication in UK primary care consultations, focussing on the communication of clinical empathy and realistic optimism. Methods A qualitative interview study was conducted as part of a multi-centre cluster-randomised trial of EMPathicO, a brief e-learning package for Primary Care Practitioners (PCPs) on communicating clinical empathy and realistic optimism. Participants were not aware whether their general practice had access to EMPathicO or not. Interviews were conducted within 7-14 days of participants' consultations, explored their views and experiences of clinical empathy and realistic optimism, and were transcribed verbatim. Interviews were analysed using Ritchie and Spencer's Framework Method. Results We conducted semi-structured audio-recorded qualitative telephone interviews with 71 participants from 29 primary care practices taking part in the EMPathicO trial. Following comprehensive mapping of data to the framework derived following initial analysis, four themes were agreed. Overall, most participants described positive empathic consultations with their PCPs, however, participants' experiences were shaped by wider systemic and contextual factors. They described a stretched and inefficient primary care system impacting empathy and optimism; the impact of PCP 'preparedness' as a marker for empathy; how consultation modality (i.e. in-person or telephone) shaped perceptions of empathy, and how PCPs sharing next steps in participants' treatment and management could foster realistic optimism. Conclusions While clinical empathy and realistic optimism may be experienced by patients during consultations with practitioners, the wider contextual challenges of accessing and navigating primary care systems can threaten overall perceptions of feeling cared for. Future primary care policy and workforce training must consider these system pressures to preserve effective communication in consultations and positive patient-practitioner encounters.

Introduction Primary care productivity and performance are hard to measure because patient health is not measured systematically and consistently. In England, productivity is measured using output (appointment volume) and two value-based metrics: waiting times and patient satisfaction. Higher productivity should improve all these metrics: more appointments should shorten waits, and shorter waits should raise patient satisfaction. However, little evidence tests how output and value-based metrics are associated. Methods We conducted a retrospective observational study of NHS primary care in England, 2018 to 2024, using Appointments in General Practice and the GP Patient Survey. Across Integrated Care Boards (ICBs), we examined the relationship between changes in appointment volume, waiting times, and patient dissatisfaction over two periods, 2018-2022 and 2022-2023, stratified by staff group and appointment mode. Results Completed appointments rose between 2018 and 2024, with care shifting towards non-GP staff and virtual delivery. Across ICBs in 2018-2022, per million additional appointments, waiting time changed by -0.04 days (95% CI: -0.10, 0.03) and dissatisfaction by 0.02 percentage points (95% CI: -0.36, 0.40). Per additional day of waiting, dissatisfaction changed by -1.40 percentage points (95% CI: -3.21, 0.42). In 2022-2023, the corresponding estimates were -0.31 days (95% CI: -0.57, -0.04), -0.75 percentage points (95% CI: -3.05, 1.56), and 2.85 percentage points (95% CI: 1.20, 4.51). Conclusion Increased appointment volume was not associated with shorter waiting times or lower patient dissatisfaction, and shorter waiting times were not associated with lower patient dissatisfaction. Either quality metrics do not respond to output, the key factor providers control, or they do not capture the dimensions of quality that matter. Performance frameworks that assess primary care productivity through these metrics should be reviewed.

Background: Maternal postpartum checks with a general practitioner (GP) are recognised as an essential service in England and vital for recovery after pregnancy and reducing risk of long-term morbidity. Despite this, its reported fewer than of women have a record of the examination in the recommended 6-8 weeks, with observed disparities in uptake nationally. The impact of the COVID-19 pandemic disrupted delivery of these checks nationally, but there is limited data on the impact of the pandemic and its recovery for regional populations representing diversity and areas of dense poverty and ethnic minority populations. This study utilised region level data to assess the impact of COVID-19 on postnatal care. Methods: Anonymised electronic health records with clinical coded birth events for females, aged 16-49 years, were analysed for patients registered with a GP using the Greater Manchester Care Record (GMCR) between January 2018 and August 2023. Unique delivery episodes were defined and monthly rates calculated separately for women with a postnatal-related code within 4-, 6-, 8-, or 12-weeks or 1 year follow-up. Rates were also generated by key maternal demographics to assess any differences in postpartum care. Interrupted time series, modelling the onset of the pandemic estimated the IRR of 0.49 (95% CI 0.40-0.58). To assess the impact of maternal characteristics on the odds of non-attendance at examination, a logistic regression adjusting for various maternal characteristics was fitted. Results: There were 114,874 unique delivery episodes, relating to 85,076 women in the 12-week follow up cohort; 72,595 episodes to 55,784 women in 8-weeks and 28,846 episodes to 24,018 women in 6-weeks. The rate of postpartum checks was greater the longer the follow-up period. For checks within 8 weeks the first lockdown reduced from ~325 per 1000 delivery episodes in 2019 to 225 per 1000 by April 2020 (30.8%), which remained low, before returning to pre-pandemic rates by rates by October 2022. Rates remained lower overall for Black, or Asian women compared to White. Conclusion: The COVID-19 pandemic reduced postnatal follow-up in primary care across Greater Manchester, with rates frequently falling outside the recommended 6-8 week window. Significant disparities exist in the provision and uptake of these services. Improved integration of data across care sites, combined with enhanced risk management, could increase equity in access and support the timely delivery of care for those at greatest risk of postnatal complications and longer-term health issues.

Objectives To evaluate the early implementation of tirzepatide for the management of obesity in primary care in England, including variations in Integrated Care Board (ICB) service delivery models, access criteria, and initial prescribing activity following national policy introduction (June 2025). This paper reports the initial phase of a wider mixed methods national evaluation of tirzepatide delivery models for initial priority cohorts defined in NHS England interim commissioning guidance. Design National study combining 1) mapping of ICB implementation plans using a questionnaire, publicly available data and documents, and stakeholder discussions, and 2) analysis of English Prescribing Dataset (EPD) to investigate tirzepatide prescribing trendsusing interrupted time-series methods to compare monthly prescriptions before and after June 2025 (implementation start) against a synthetic control series based on semaglutide prescribing. Setting ICBs across England. Participants 23/42 ICBs (55%) responded, of which 13 also took part in stakeholder meetings. For 17 ICBs (40%), we additionally extracted information from publicly available documents. Main outcome measures Descriptions of service delivery models, access criteria, and ICB characteristics; stakeholder-reported implementation challenges; and prescribing trends over time. Results We were able to categorise models of care for 40/42 ICBs. A general practice-led delivery model was most commonly planned (18/40; 45%), followed by community/local-based delivery (8; 20%), custom models (8; 20%), and specialist weight management service (SWMS) community outreach (6; 15%). Four ICBs (10%) planned to use more than one model of care. Most ICBs reported following national priority cohort eligibility criteria 31/39 (79%), while eight (21%) applied additional prioritisation criteria due to funding constraints. Stakeholder discussions highlighted variation in the interpretation of model definitions, variation in operationalisation, and challenges related to affordability, insufficient workforce capacity, and tight timelines, with some ICBs not yet prescribing at the time of stakeholder meetings (November 2025). Analyses of EPD showed a steady increase in tirzepatide prescribing over time, with no evidence that the June 2025 policy implementation date produced any additional increase beyond background diabetes-related trends. Conclusions Early implementation of tirzepatide prescribing in primary care has been characterised by heterogeneous service models, local adaptations of access criteria, and slow implementation of obesity-related prescribing. Findings highlight the challenges of implementing new pharmacological treatments including patient management within routine care and the need for clear guidance, realistic timelines, and system capacity. Ongoing evaluation is needed to understand how service models evolve and implications for access, equity, and outcomes.

Background Iron deficiency (ID) is a readily treatable condition once identified. Ferritin is the primary diagnostic marker, but cut-offs vary and inflammation complicates interpretation in patients with long-term conditions (LTCs). Aim To describe ferritin distribution and the prevalence of threshold-defined low ferritin in adults with and without LTCs in primary care. Design and setting Cross-sectional observational study using routinely collected electronic health records from a national primary care database in England (1st January 2015 to 31st December 2021). Method Adults with >1 ferritin test in Clinical Practice Research Datalink (CPRD) Aurum were included. LTCs were identified using validated primary-care code lists. Outcomes included ferritin distribution and threshold-defined ID prevalence using World Health Organization (WHO) (<15 ug/L; <70 ug/L if inflammation) and National Institute for Health and Care Excellence (NICE) (<30 ug/L) cut-offs, stratified by sex and, in women, by age <50 versus >=50 as a proxy for menopausal status. Results 4,489,594 individuals were included; 55% (n=2,469,882) had >1 LTC. Ferritin was lowest in women <50 and in LTCs characterised by impaired absorption or blood loss (coeliac disease, inflammatory bowel disease). Among women <50 with an LTC, 80% had ferritin <70 ug/L versus 47% <30 ug/L, leaving 33% in the 30 to 70 ug/L range potentially missed by standard cut-offs; equivalent figures were 28% in women >=50 and 17% in men. Conclusion Threshold-defined low ferritin is very common across LTCs and disproportionately affects women, particularly those under 50. Condition-specific, inflammation-adjusted ferritin thresholds may improve detection, management, and equity in primary care.

Background: Two-thirds of Dutch cardiovascular risk management (CVRM) for patients at risk of cardiovascular disease is delivered in primary care practices. While individual risk scores are increasingly used during consultation, a population-level structure for risk-based patient outreach is not currently available. We therefore developed the PROSPERA programme, a multilevel intervention comprising population-level risk stratification and individual-level support tools. Aim: To assess anticipated and experienced barriers and facilitators among healthcare professionals (HCPs) to inform implementation in primary care. Methods: We conducted four focus groups and six interviews with nine primary care HCPs to explore anticipated and experienced barriers and facilitators. Inductive codes were thematically analysed and assigned to corresponding domains of the Theoretical Domains Framework (TDF) and the related Capability, Opportunity, Motivation model of Behaviour. Results: Barriers and facilitators were identified in 11 TDF domains. Population-level barriers included altered professional roles and limitations in technological infrastructure. Individual-level barriers were limited skills in interpreting risk calculations and difficulty integrating tools into clinical routine. Facilitators were related to beliefs on the importance of providing proactive care (population level), the use of U-Prevent for risk communication (individual level) and positive patient responses to the Lifestylecheck questionnaire (individual level). Conclusion: Addressing barriers and facilitators identified at both the population and individual levels can support implementation of the PROSPERA programme. Opportunities exist in education and training of HCPs in risk communication, as well as support in restructuring the physical and digital environment.

Mobile clinical-support applications can facilitate access to evidence-based information at the point of care, but evidence on their usability and perceived usefulness among newly graduated physicians working in health facilities with limited capacity is scarce. We assessed physicians experiences with BMJ Best Practice using a convergent mixed-methods study. All 81 eligible physicians assigned to rural facilities were invited; 32 enrolled and received application access and training. After three months, participants completed an online survey, and 23 reported using the application. Ten physicians reporting the highest consultation frequency were purposively selected for semi-structured interviews. Survey findings showed a predominantly favorable perception of usability: for most items, 70%-90% of participants agreed or strongly agreed with the statements assessed. Among users, 14 of 23 (60.9%) used the mobile application and 9 (39.1%) used the web version. Interviews indicated that participants valued rapid searches, organized and evidence-based information, and support for diagnostic reasoning, referral decisions, learning, and clinical confidence. Barriers included limited connectivity, difficulties searching in Spanish, automatic updates, challenges locating or using some calculators, and treatment information that was sometimes insufficiently specific. Most importantly, participants could not always implement recommendations because suggested medicines, diagnostic tests, or other resources were unavailable in their facilities. Mobile clinical-support applications may complement decision-making and learning among early-career physicians in rural primary care. However, their practical value depends not only on usability and evidence quality, but also on adaptation to users language, workflow, connectivity, and local service capacity.

Purpose In deprescribing studies, a prescription-free gap is typically used to determine if patients discontinued their treatment. An appropriate gap depends on the typical time between prescriptions during continued use. This work aims to characterise the interval between prescriptions of chronic drugs using different methods for a cohort of older people in primary care in Ireland. Methods The empirical prescription interval was analysed for 38,154 patients for the twenty most common drug classes and the association between covariates and the interval was analysed using a multi-level model. Estimates were also compared to those obtained from the parametric waiting time distribution (pWTD) approach. Results Available covariates had consistent relationships with prescription intervals across drug classes. For example, each additional prescription issue was associated with an increase in the interval by 5.0 (NSAIDs) to 19.7 days ("Other antidepressants"). Full public health cover was associated with a -29.0 day (inhaled adrenergics) to -11.0 day (opioids) change relative to partial cover, while other/private cover had a -17.9 day (benzodiazepines and associated drugs) to -7.1 day (SSRI and SNRIs) change relative to partial cover. The pWTD also produced consistent estimates of the population interval for most drugs. Conclusions The interval varied substantially within drug classes, due to a mixture of patient, practice and unmodelled factors. Variation between practices was effectively explained, with residual variation between patients and within patients. The pWTD approach is useful for describing complex distributions of intervals, and may be more appropriate for inferring a gap than summarising truncated data.

Aims To develop a 'core' dataset of diabetes related variables to support reproducible research using UK routinely collected health data. Methods A workshop was conducted bringing together diabetes healthcare professionals, researchers, and patient and public representatives to discuss and prioritise variables for inclusion in the Diabetes Core Dataset. Core variables were those considered to be highest priority for diabetes research and available at high quality in NHS data routinely used for research (primary care [GP] and Hospital Episode Statistics [HES] data). Candidate variables for inclusion in the Diabetes Core Dataset were from a review of existing core datasets and expert opinion. Participants scored variables anonymously based on priority for diabetes research. Results 25 variables from existing diabetes core datasets and 87 other candidate variables were considered for inclusion in the Diabetes Core Dataset. All 25 of those from existing diabetes core datasets and 5 of the 87 candidate variables met the core requirements for inclusion. In addition, 7 variables were identified as high priority but not included in the core dataset as they are not currently available in GP/HES data; these were labelled as 'future high priority' variables for diabetes research. Conclusions A new diabetes core dataset for UK EHR research has been developed using a consensus-based process. The core dataset is openly available and can be flexibly applied in UK EHR (https://healthdatagateway.org/en/tool/426), including in new NHS Research Secure Data Environment platforms, to enhance reproducible research to improve the clinical care of people with diabetes and associated conditions.

Background The number of novel cancer therapies approved for use in England by the National Institute for Health and Care Excellence is increasing. Monitoring the adoption of new therapies is important to assess equity of access and evaluate real-world prescribing practices. OpenPrescribing Hospitals has recently been launched to facilitate analysis of open secondary care medicines data in England. Using this platform, we set out to describe the use of cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors, including the frequency of dose reductions, within National Health Service (NHS) hospitals in England between January 2019 and December 2024. Methods The monthly proportion of each CDK4/6 inhibitor relative to total CDK4/6 inhibitor use was calculated at hospital level. Regional variation was assessed across Cancer Alliances by comparing the proportions of each CDK4/6 inhibitor used within each alliance in 2021 and 2024. Use of lower strength palbociclib and abemaciclib was used as a proxy for dose reductions. Findings There was more than a 3-fold increase in the use of CDK4/6 inhibitors between 2019 and 2024. In 2019, 78.6%, 11.9% and 9.5% of CDK4/6 inhibitors used were palbociclib, abemaciclib and ribociclib, compared with 40.2%, 41.2% and 18.6% in 2024. There was variation in the relative percentage change in use of each agent by Cancer Alliance. Use of lower strengths was common for both palbociclib (60%) and abemaciclib (63%). Interpretation Changes in usage appeared responsive to publication of key evidence and regulatory milestones. There was a higher apparent frequency of dose reductions than reported in clinical trials. OpenPrescribing Hospitals is an accessible, publicly available tool for understanding uptake and use of medicines in NHS hospitals in England.

Background: Given around 50% of people with heart failure have a degree of iron deficiency, guidelines recommend screening. It is uncertain to what extent this is done in primary care and whether testing is equitable. Aim: To report the proportion of people with incident heart failure who undergo a ferritin test within 12 months. Design and setting: Retrospective primary care cohort study using Clinical Practice Research Datalink Aurum data, between 2016 and 2021. Methods: We report the proportion of adults with an incident diagnosis of heart failure who received a ferritin test within 12 months. Multivariable logistic regression was used to examine the odds of testing based on key demographic covariates and co-morbidities. Results: Among 105,749 individuals with an incident diagnosis of heart failure (mean age 71.6 years, SD 14.3), only 35,688 (33.7%) received a ferritin test within the subsequent year. Increasing age (odds ratio 1.25 per 10-year increase, 95% CI: 1.24-1.27), female sex (male sex OR 0.86, 0.84-0.89) and Asian ethnicity (OR 1.70, 1.59-1.80) were all associated with increased odds of testing as were diagnoses of coeliac disease (OR 1.86, 1.58-2.21), type 1 diabetes (OR 1.82, 1.51-2.19) and cirrhosis (OR 1.64, 1.43-1.87). There was geographic variation in testing, even in adjusted analyses. Conclusion: In a large primary care dataset, two thirds of people with incident heart failure did not receive a ferritin test for iron deficiency within a year of diagnosis demonstrating a gap in current practice and an opportunity for improvements in service delivery.

Study Objective Little is known about where in hospital care for multiple long-term conditions (MLTC) is delivered. We aimed to describe pathways of care (ward transfers) and outcomes for people admitted to hospital for unscheduled care by MLTC status and other key sociodemographic characteristics. Design and setting Analysis of routinely-collected electronic health records from a large acute UK hospital. Participants Adult unscheduled care admissions from 1st July 2018 to 30th June 2019. The presence of two or more of 59 long-term conditions was ascertained using ICD-10 codes from previous hospital discharges. Main outcome measures Markov state transition probabilities were derived for ward moves and compared for MLTC vs no MLTC, age, sex, ethnicity and neighbourhood deprivation. Outcomes (length of stay, death, readmission, move from definitive ward) and time spent in emergency and assessment departments were compared between subgroups. Results A total of 33,252 adults, mean age 56.0 (SD 21.9) years were analysed; 14,834 (42.4%) had MLTC. People with MLTC were more likely to die in hospital (4.2 vs 1.9%, p<0.001), transfer to internal medicine wards or older peoples medicine wards, were less likely to transfer to surgical wards, had longer median length of stay (1.83 vs 0.69 days, p<0.001), stayed longer in acute medical units (15.5 vs 9.6 hours, p<0.001), and were more likely to move from their definitive ward (18.2 vs 16.4%, p=0.002). Conclusion Unscheduled hospital care pathways are complex and differ for people with MLTC, who have worse outcomes and may be less likely to receive optimal care.

Objective: to describe the provision of preconception care across publicly funded or contracted health and social care settings in the UK. Design and setting: online cross-sectional survey conducted October-December 2025. Population: healthcare professionals delivering preconception care, recruited via professional organisations and networks. Methods: quantitative data were analysed using descriptive statistics and qualitative free-text responses using inductive content analysis. Outcome measures: preconception care content, target population, frequency of provision, funding and commissioning models, and approaches for reporting and monitoring. Results: Eighty-seven healthcare professionals completed the survey. Most were women (89.3%), aged 41-60 (63.1%) and based in England (84.5%). Participants represented diverse roles, mainly obstetric/maternal-fetal specialists (23.0%), specialist nurses (16.0%), GPs and midwives (13.8% each). Preconception care primarily targeted women [&ge;]20 years (98.9%), with fewer targeting men and adolescents. Care was usually embedded within relevant consultations (69.4%), particularly contraception, medication and health condition reviews, and often a one-off interaction (75.3%). Content focused on condition-related management/medication (68.6%), folic acid (66.3%), risky behaviours (smoking, alcohol, illicit drugs) (40.7%), diet (37.2%) and weight (36.0%). Services were mostly not formally commissioned (62.4%), lacked financial incentives (84.7%) and had no audit/service evaluation requirements (81.2%). Conclusions: Preconception care in the UK is delivered by a wide range of healthcare professionals. Their engagement has improved considerably when compared with studies conducted over a decade ago, but preconception care remains fragmented, opportunistic and poorly supported by commissioning and system infrastructure. Strengthening integrated care pathways, funding mechanisms and use of standardised resources is essential to achieve consistent and equitable preconception care.

Purpose: Serious Illness Conversations (SICs) are essential to delivering person-centered care for older adults with chronic conditions, but are rarely integrated into routine primary care. To address this gap, we compared the effectiveness of a structured training strategy versus passive dissemination of educational materials on SIC documentation rates during the COVID-19 pandemic. Methods: A quasi-experimental study across 13 primary care clinics in Quebec, Canada. Five clinics received structured team-based Serious Illness Care Program training (intervention group) with a provincially disseminated SIC toolkit and eight received the toolkit only (control group). The primary outcome was the proportion of patients with a documented SIC across three time periods (Period 1, pre pandemic; Period 2, pandemic initial wave; and Period 3, post dissemination of SIC toolkit). We used generalized estimating equations (GEE). Results: Across 13 clinics, 2,368 eligible patients (mean age 75.8 years (SD = 7.5), 54% female, with a mean Charlson Comorbidity Index of 4.88 (SD = 2)) accounted for 19,134 clinical visits, 49.5% in person and 49.6% virtually. SIC documentation rates were 3.3% (control) and 3.4% (intervention) in Period 1, 9.3% and 4.3% in Period 2, and 6.4% and 4.8% in Period 3, respectively. There was no statistically significant improvement to SIC documentation in the intervention group at Period 2 nor Period 3. Conclusion: Structured training was not more effective than passive dissemination for SIC documentation. Educational interventions must be supported by structural changes, workflow integration, and organizational leadership. Multi-level implementation strategies are needed to embed SICs sustainably into primary care.

Background: Rheumatic heart disease (RHD) remains a major cause of premature death in low- and middle-income countries and First Nations communities. Early detection and management can prevent progression, but requires echocardiography, which is limited in high-burden settings. Task-sharing echocardiographic screening is an accessible, evidence-based approach but implementation remains unclear. Methods: We conducted a prospective implementation evaluation of a co-designed task-sharing screening programme across five remote First Nations Australian communities between May 2023 and November 2025. Predominantly community health workers (CHWs), alongside nurses and doctors, were trained to scan using handheld devices with off-site cardiologist interpretation. We assessed implementation outcomes and used a realist evaluation to explore how context shaped CHWs ability to complete training and embed screening into routine work. Data included scanning activity, surveys, costing, interviews, focus groups, and field notes. Findings: We trained 32 staff (21 CHWs, 8 nurses, 3 doctors) to scan across five sites. Scanning frequency was lower and more variable than anticipated: 360 scans (including training and post-certification) of 5 - 20 year olds over 14 months, with site-level coverage of 3 - 85%. Fidelity was limited by device unavailability, charging problems, and delays in uploads and reviews. Set-up and training cost A$51,903 per site, plus A$9,858/year in implementation support. Screening was easier for CHWs to embed when the legitimacy of their role as a scanner was communicated, but harder when invisible work outweighed opportunities to scan. Interpretation: Future implementation will require efforts to legitimise CHWs scanning and support invisible work. Event-based screening offers a promising complementary strategy. Scale-up requires policy support. Funding: This research was funded by the Australian Medical Research Futures Fund Cardiovascular Health Mission (GNT2015869), in addition to philanthropic donations from Medtronic Australasia, Edwards Life Sciences and the Rotary Club of Kiama. Hand-held devices (Philips Lumify, USA) were donated by Humpty Dumpty Foundation and East Timor Hearts Fund.

Objectives To assess the concurrent and lagged associations between quality of primary care and planned and unplanned secondary care use for patients with multimorbidity, examining the modifying role of frailty. Design A retrospective cohort study Setting This population-level analysis included 468,172 patients with multimorbidity in England from the Discover research platform (April 2022-March 2024). Participants Patients with multimorbidity Main outcome measures We used principal component analysis to combine a set of quality indicators (QIs) and assessed the impacts of QIs on both planned and unplanned care. Results Generally, patients with higher QI attainment also had higher likelihood of planned (outpatient visits) and unplanned care (emergency admissions and ED visits) utilisation. There was a lower lagged odds of elective hospital admissions in the following 12 months among those with higher attainment of multimorbidity-specific QIs (OR=0.94, 95%CI 0.93-0.95). In the complex multimorbidity cohort ([&ge;]3 conditions), multimorbidity-specific QIs were longitudinally associated with lower odds of elective admissions (OR=0.94, 95%CI 0.92-0.95) and outpatient visits (OR=0.96, 95%CI 0.95-0.98), while generic QIs were related to lower odds of outpatient non-attendance (OR=0.95, 95%CI 0.91-0.99). In non-frail patients with multimorbidity, multimorbidity-specific QIs were longitudinally associated with reduced odds of outpatient visits (OR=0.98, 95%CI 0.97-0.99), elective admissions (OR=0.92, 95%CI 0.90-0.94) and prolonged elective hospital stay (IRR=0.94, 95%CI 0.89-0.99). Conclusions Attainment of generic and multimorbidity QIs was generally associated with slightly increased planned and unplanned care. However, patients for whom we identified higher attainment of multimorbidity-specific QIs had lower odds of elective admissions and outpatient visits, especially for those with complex multimorbidity. Our research suggests that the quality of primary care may influence patients' use of secondary care, with the potential to improve care for people with multimorbidity and warrant further investigation into management strategies.

Objectives: The Pharmacy First (PF) service was introduced across England from 31 January 2024 to expand the clinical role of community pharmacies and improve access to primary care. This paper describes use of PF in its first 12 months, in terms of uptake, access routes, consultation outcomes, geographic variations, service costs and antimicrobial supply. Methods: A descriptive analysis of all PF consultations submitted for payment to NHS Business Services Authority in England between 31 January 2024 and 31 January 2025. Pharmacy-level consultation data were linked to national data on population, location and pharmacy characteristics. PF use was examined using population-standardised consultation rates and consultations per pharmacy. Results: During the first year of implementation, 2,205,731 PF consultations were recorded as delivered across 11,349 pharmacies, with payment of GBP123 million to pharmacies. Uptake increased steadily over time. Most consultations were for acute sore throat (33%) and uncomplicated urinary tract infection (27%), with corresponding antibiotics, phenoxymethylpenicillin and nitrofurantoin being the most supplied. Most people self-referred (74%) into the service, with 95% of consultations managed without onward referral. Substantial geographic variation was observed. Northern regions had higher use based on the eligible population. The South East and Midlands had higher activity per pharmacy. London showed a distinct pattern, with higher self-referral into the service, lower medication supply and higher referral to other healthcare services. Higher consultation volume was weakly associated with pharmacy characteristics, including opening hours, pharmacy type and retail setting, and local context, in terms of socio-economic and geographic factors. Conclusions: PF had immediate uptake and is operating primarily as a direct-access model for common acute conditions. Findings suggest that PF is contributing to improved access to care and may shift demand away from general practice. However, the service uptake appears to be shaped by geographic location, proximity to other healthcare services and pharmacy characteristics.

Background: Public and clinical attention to postural orthostatic tachycardia syndrome (POTS) has increased, particularly since the COVID-19 pandemic. We quantified changes in United Kingdom Google search interest and examined whether searches increasingly used diagnostic and self-assessment language. Methods: We extracted monthly Google Trends relative search volume (RSV; 0-100) for the Health-category search term 'Pots syndrome' in the United Kingdom from January 2004 through July 2026. Five extraction attempts were made; two returned complete, identical monthly series and were retained. Prespecified eras were summarised and an exploratory interrupted time-series model at March 2020 used ordinary least squares with Newey-West heteroskedasticity and autocorrelation consistent standard errors (12 lags). Comparator searches included conventional orthostatic diagnoses, POTS diagnostic terms, associated conditions and YouTube searches. Results: The primary series comprised 271 complete months. Mean RSV increased from 18.6 during 2015-2019 to 64.8 during 2022-2023 (3.49-fold) and remained 50.6 during January 2024-July 2026 (2.73-fold above baseline). Search interest peaked in October 2022 (RSV 100); July 2026 RSV was 57. The interrupted time-series model estimated an immediate March 2020 level increase of 21.8 points (95% CI 2.8-40.7; p=0.024), while the slope change was not statistically supported (0.069 points/month, 95% CI 0.299 to 0.438; p=0.713). Searches for 'POTS symptoms', 'POTS test' and 'POTS heart rate' increased more steeply than the general term, although low baseline volumes made fold changes unstable. Conclusions: UK Google search interest in POTS rose before 2020, increased sharply after the pandemic began, and remained substantially above its prepandemic baseline. The results demonstrate a sustained change in public attention, not disease incidence or social-media causation. The growth of symptom- and testing-oriented searches is compatible with increased diagnostic self-investigation and warrants linkage to referral, diagnosis and social-media exposure data.
