There is a need to increase flu vaccination rates in England particularly among those under 65 years of age and at risk because of other conditions and treatments. Patients in at risk groups are eligible for free vaccination on the National Health Service (NHS) in England, but despite this, some choose to pay privately. This paper explores how prevalent this is and why people choose to do it. There is moderate to good evidence from several countries that community pharmacies can safely provide a range of vaccinations, largely seasonal influenza Immunisation. Pharmacy-based services can extend the reach of immunisation programmes. User, doctor and pharmacist satisfaction with these services is high.

Aims: Pharmacogenetics (PGx) in the UK is currently implemented in secondary care for a small group of high‐risk medicines. However, most prescribing takes place in primary care, with a large group of medicines influenced by commonly occurring genetic variations. The goal of this study is to quantitatively estimate the volumes of medicines impacted by implementation of a population‐level, pre‐emptive pharmacogenetic screening programme for nine genes related to medicines frequently dispensed in primary care in 2019.Methods: A large community pharmacy database was analysed to estimate the national incidence of first prescriptions for 56 PGx drugs used in the UK for the period 1 January–31 December 2019. These estimated prescription volumes were combined with phenotype frequency data to estimate the occurrence of actionable drug–gene interactions (DGI) in daily practice in community pharmacies.Results: In between 19.1 and 21.1% (n = 5 233 353–5 780 595) of all new prescriptions for 56 drugs (n = 27 411 288 new prescriptions/year), an actionable drug–gene interaction (DGI) was present according to the guidelines of the Dutch Pharmacogenetics Working Group and/or the Clinical Pharmacogenetics Implementation Consortium. In these cases, the DGI would result in either increased monitoring, guarding against a maximum ceiling dose or an optional or immediate drug/dose change. An immediate dose adjustment or change in drug regimen accounted for 8.6–9.1% (n = 2 354 058–2 500 283) of these prescriptions.Conclusions: Actionable drug–gene interactions frequently occur in UK primary care, with a large opportunity to optimise prescribing.

Recent work has reported that respiratory audio-trained AI classifiers can accurately predict SARS-CoV-2 infection status. However, it has not yet been determined whether such model performance is driven by latent audio biomarkers with true causal links to SARS-CoV-2 infection or by confounding effects, such as recruitment bias, present in observational studies. Here we undertake a large-scale study of audio-based AI classifiers as part of the UK government’s pandemic response. We collect a dataset of audio recordings from 67,842 individuals, with linked metadata, of whom 23,514 had positive polymerase chain reaction tests for SARS-CoV-2. In an unadjusted analysis, similar to that in previous works, AI classifiers predict SARS-CoV-2 infection status with high accuracy (ROC–AUC = 0.846 [0.838–0.854]). However, after matching on measured confounders, such as self-reported symptoms, performance is much weaker (ROC–AUC = 0.619 [0.594–0.644]). Upon quantifying the utility of audio-based classifiers in practical settings, we find them to be outperformed by predictions on the basis of user-reported symptoms. We make best-practice recommendations for handling recruitment bias, and for assessing audio-based classifiers by their utility in relevant practical settings. Our work provides insights into the value of AI audio analysis and the importance of study design and treatment of confounders in AI-enabled diagnostics.

The UK Community Pharmacy Future group developed the Pharmacy Care Plan (PCP) service with a focus on patient activation, goal setting and therapy management. To estimate the effectiveness and cost-effectiveness of the PCP service from a health services perspective. Patients over 50 years of age prescribed one or more medicines including at least one for cardiovascular disease or diabetes were eligible. Medication review and person-centred consultation resulted in agreed health goals and actions towards achieving them. Clinical, process and cost-effectiveness data were collected at baseline and 12-months between February 2015 and June 2016. Mean differences are reported for clinical and process measures. Costs (NHS) and quality-adjusted life year scores were estimated and compared for 12 months pre- and post-baseline. Seven hundred patients attended the initial consultation and 54% had a complete set of data obtained. There was a significant improvement in patient activation score (mean difference 5.39; 95% CI 3.9-6.9; p < 0.001), systolic (mean difference -2.90 mmHg; 95% CI -4.7 to -1; p = 0.002) and diastolic blood pressure (mean difference -1.81 mmHg; 95% CI -2.8 to -0.8; p < 0.001), adherence (mean difference 0.26; 95% CI 0.1-0.4; p < 0.001) and quality of life (mean difference 0.029; 95% CI 0.015-0.044; p < 0.001). HDL cholesterol reduced significantly and QRisk2 scores increased significantly over the course of the 12 months. The mean incremental cost associated with the intervention was estimated to be £202.91 (95% CI 58.26 to £346.41) and the incremental QALY gain was 0.024 (95% CI 0.014 to 0.034), giving an incremental cost per QALY of £8495. Enrolment in the PCP service was generally associated with an improvement over 12 months in key clinical and process metrics. Results also suggest that the service would be cost-effective to the health system even when using worst case assumptions.

As part of the NHS desire to move services closer to where people live, and provide greater accessibility and convenience to patients, Brighton and Hove Clinical Commissioning Group (CCG) underwent a review of their anticoagulation services during 2008. The outcome was to shift the initiation and monitoring service in secondary care for non-complex patients, including domiciliary patients, into the community. This was achieved via a procurement process in 2008 resulting in the Community Pharmacy Anticoagulation Management Service (CPAMs) managed by Boots UK (a large chain of community pharmacies across the United Kingdom). This evaluation aims to review the outcomes (International Normalised Ratio [INR] readings) and experiences of those patients attending the anticoagulation monitoring service provided by community pharmacists in Brighton and Hove. All patients on warfarin are given a target INR range they need to achieve; dosing of and frequency of appointment are dependent on the INR result. Outcome measures for patients on the CPAM service included percentage INR readings that were within target range and the percentage time the patient was within therapeutic range. Data collected from 2009 to 2016 were analysed and results compared to the service targets. Patient experience of the service was evaluated via a locally developed questionnaire that was issued to patients annually in the pharmacy. The evaluation shows that community pharmacy managed anticoagulation services can achieve outcomes at a level consistently exceeding national and local targets for both percentage INR readings in therapeutic target range (65.4%) compared to the recommended minimum therapeutic target range of 60.0% and percentage time in therapeutic range (72.5%, CI 71.9–73.1%) compared to the national target of 70.0%. Patients also indicated they were satisfied with the service, with over 98.6% patients rating the service as good, very good or excellent. The Brighton and Hove CPAM service achieved above average national target management of INR and positive patient feedback, demonstrating that community pharmacy is ideally placed to provide this service safely and deliver enhanced clinical outcomes and positive patient experience.

Community pharmacy services have evolved to include medical and pharmaceutical interventions alongside dispensing. While established pharmacogenomic (PGx) testing is available throughout the Netherlands, this is primarily based in hospital environments and for specialist medicines. The aim of this work was to describe how best to implement PGx services within community pharmacy, considering potential barriers and enablers to service delivery and how to address them. The service was implemented across a selection of community pharmacies in the Netherlands. Data were captured on test outcomes and through a pharmacist survey. Following testing, 17.8% of the clinical samples were recommended to avoid certain medication (based on their current medicines use), and 14.0% to have their dose adjusted. Pre-emptive analysis of genotyped patients showed that the majority (99.2%) had actionable variants. Pharmacists felt confident in their operational knowledge to deliver the service, but less so in applying that knowledge. Delivering the service was believed to improve relationships with other healthcare professionals. These results add to the evidence in understanding how PGx can be delivered effectively within the community pharmacy environment. Training pharmacists in how to respond to patient queries and make clinical recommendations may enhance service provision further.
