Effectiveness of Influenza Vaccination in Reducing Subsequent Antibiotic Prescribing in Young Children Attending Australian General Practices-A Case-Control Study.

Vaccination against influenza may reduce antibiotic use, but data are limited and imprecise. We conducted a case-control study using deidentified data from a large national primary care database to evaluate antibiotic prescribing changes following influenza vaccination in children 1-4 years old attending primary care in the Australian 2018 and 2019 influenza seasons. Cases were prescribed β-lactam or macrolide antibiotics during the influenza season and controls were not. Influenza vaccination was documented in the medical records. Adjusted odds ratios for antibiotic prescribing according to influenza vaccination status were estimated using generalized estimating equations, controlling for age, asthma diagnosis, other vaccinations, practice visit frequency, and attendance week. In 2018, 11282 cases and 32020 controls were eligible, and in 2019, 12705 cases and 36858 controls. Antibiotic prescriptions were less likely in vaccinated participants in 2018 (aOR, 0.65; 95% CI, 0.62-0.69) and 2019 (aOR, 0.78; 95% CI, 0.73-0.82) and did not vary by age, the number of GP visits, or prior prescribing of antibiotics. In the subgroup of children vaccinated in the preceding season, influenza vaccination was not associated with a reduction in antibiotic use (2018-aOR, 1.12; 95% CI, 0.90-1.39; 2019-aOR, 1.30; 95% CI, 1.16-1.46). From our estimates, potentially 100000 antibiotic prescriptions could be avoided annually in Australia if all children in this age range were vaccinated. Influenza vaccination may substantially reduce antibiotic prescribing among young children. This effect should be considered in the overall assessment of the costs and benefits of childhood influenza vaccination programs.

Effect of the COVID-19 pandemic on contraceptive prescribing in general practice: a retrospective analysis of English prescribing data between 2019 and 2020

ObjectivesThis paper looks at how contraceptive prescribing by General Practices in England was affected by the COVID-19pandemic and lockdown. It compares English prescribing data in April – June 2019, the year before COVID19, and April–June 2020, the first three months of ‘lockdown’.Design & SettingThis paper is based on retrospective analysis of the English Prescribing Dataset which reports monthly on prescribed items from English General Practices. Data on all forms of prescribed contraceptive methods were extracted using BNF codes, and total quantities tabulated by method. To reach the total number of months of contraception provided, total quantities were divided or multiplied according the frequency with which the method is taken per month or the numbers of months of contraception provided.ResultsPrescription of the combined oral contraceptive pill reduced by 22% during the period of lockdown compared to the same three months in 2019. Prescriptions of Progestogen-Only pills remained stable. Prescription of long-acting methods reduced, with the greatest reductions in implants (76% reduction from pre-lockdown levels), intra-uterine systems (79% reduction from pre-lockdown levels) and intrauterine devices (76% reduction from pre-lockdown levels).ConclusionsThe disruption of face-to-face contraceptive consultations in General Practice during a COVID-19 ‘lockdown’ has resulted in a reduction in oestrogen –containing methods compared to progestogen-only methods, which require less face-to-face monitoring.Implant and intrauterine contraceptive device prescription reduced by three quarters over the first three months of lockdown, which has the potential to result in a rise in unintended pregnancies.

Effect of the Covid pandemic on progestogen-only and oestrogen-containing contraceptive prescribing in general practice: a retrospective analysis of English prescribing data

Objectives This paper looks at how trends in contraceptive prescribing by General Practices in England were affected by the Covid pandemic and lockdown. It compares English prescribing data from May 2014 to May 2021, including the period of ‘lockdown’, from April 20-June 20. Design & Setting A retrospective analysis of the English Prescribing Dataset which reports monthly on prescribed items from English General Practices was carried out. Data on all forms of prescribed contraceptive methods were extracted using British National Formulary (BNF) codes, and total quantities tabulated by method, then transformed into ‘months of contraception provided’ by each method. Results Prescription of the combined oral contraceptive pill reduced by 22% during the period of lockdown compared to the same three months in 2019. Prescriptions of Progestogen-Only pills remained stable. This continued a trend in oral contraceptive prescribing evident from May14. Prescription of long-acting methods reduced during the period of lockdown, with the greatest reductions in implants (76% reduction from pre-lockdown levels), intra-uterine systems (79% reduction from pre-lockdown levels) and intrauterine devices (76% reduction from pre-lockdown levels). These rates of contraceptive provision recovered quickly after the period of lockdown ended. Conclusions The disruption of face-to-face contraceptive consultations in General Practice during a Covid-19 ‘lockdown’ has resulted in a reduction in oestrogen –containing methods compared to progestogen-only methods, which require less face-to-face monitoring. Implant and intrauterine contraceptive device prescription reduced by three quarters over the first three months of lockdown, but rebounded in the next year.

Factors associated with C-reactive protein testing when prescribing antibiotics in general practice: a register-based study

BackgroundThe use of C-reactive protein (CRP) tests has been shown to safely reduce antibiotic prescribing for acute respiratory tract infections (RTIs). The aim of this study was to explore patient and clinical factors associated with the use of CRP testing when prescribing antibiotics recommended for RTIs.MethodsA nation-wide retrospective cross-sectional register-based study based on first redeemed antibiotic prescriptions issued to adults in Danish general practice between July 2015 and June 2017. Only antibiotics recommended for treatment of RTIs were included in the analysis (penicillin-V, amoxicillin, co-amoxicillin or roxithromycin/clarithromycin). Logistic regression models were used to estimate odds ratios for patient-related and clinical factors on performing a CRP test in relation to antibiotic prescribing.ResultsA total of 984,149 patients redeemed at least one antibiotic prescription during the two-year period. About half of these prescriptions (49.6%) had an RTI stated as the indication, and a CRP test was performed in relation to 45.2% of these scripts.Lower odds of having a CRP test performed in relation to an antibiotic prescription was found for patients aged 75 years and above (OR 0.82, 95CI 0.79–0.86), with a Charlson Comorbidity Index of more than one (OR 0.93, 95CI 0.91–0.95), unemployed or on disability pension (OR 0.84, 95CI 0.83–0.85) and immigrants (OR 0.91, 95CI 0.88–0.95) or descendants of immigrants (OR 0.90, 95CI 0.84–0.96). Living with a partner (OR 1.08, 95CI 1.07–1.10), being followed in practice for a chronic condition (OR 1.22, 95CI 1.18–1.26) and having CRP tests performed in the previous year (OR 1.78, 95CI 1.73–1.84) were associated with higher odds of CRP testing in relation to antibiotic prescribing.ConclusionsDifferences were observed in the use of CRP tests among subgroups of patients indicating that both sociodemographic factors and comorbidity influence the decision to use a CRP test in relation to antibiotic prescriptions in general practice. Potentially, this means that the use of CRP tests could be optimised to increase diagnostic certainty and further promote rational prescribing of antibiotics. The rationale behind the observed differences could be further explored in future qualitative studies.

A Comparative Safety Analysis of Medicines Based on the UK Pharmacovigilance and General Practice Prescribing Data in England.

Adverse drug reactions (ADRs) represent a major concern leading to significant increases in both morbidity and mortality globally. Providing healthcare professionals (HCPs) and patients with real-world data on drug safety is imperative to facilitate informed decision-making. The study aimed to determine the feasibility of creating comparative safety charts for medicines by mapping ADR reporting onto prescribing data. Data on serious and fatal ADR reports from the Yellow Card database was mapped onto general practice prescription data in England. The rate of serious and fatal ADR reports per million items prescribed was calculated for commonly-prescribed medicines. Quantitative comparative analyses for 137 medicines belonging to 26 therapeutic classes were conducted. Significant differences were observed within most therapeutic classes for the rate of serious and fatal ADR reports per prescribing unit. Despite the limitations of ADR reporting and prescribing databases, the study provides a proof-of-concept for the feasibility of mapping ADR reporting onto prescribing data to create comparative safety charts that could support evidence-based decision-making around formulary choices.

COVID-19 Patient Management in Outpatient Setting: A Population-Based Study from Southern Italy.

Evidence on treatments for early-stage COVID-19 in outpatient setting is sparse. We explored the pattern of use of drugs prescribed for COVID-19 outpatients’ management in Southern Italy in the period February 2020–January 2021. This population-based cohort study was conducted using COVID-19 surveillance registry from Caserta Local Health Unit, which was linked to claims databases from the same catchment area. The date of SARS-CoV-2 infection diagnosis was the index date (ID). We evaluated demographic and clinical characteristics of the study drug users and the pattern of use of drugs prescribed for outpatient COVID-19 management. Overall, 40,030 patients were included in the analyses, with a median (IQR) age of 44 (27–58) years. More than half of the included patients were asymptomatic at the ID. Overall, during the study period, 720 (1.8%) patients died due to COVID-19. Azithromycin and glucocorticoids were the most frequently prescribed drugs, while oxygen was the less frequently prescribed therapy. The cumulative rate of recovery from COVID-19 was 84.2% at 30 days from ID and it was lower among older patients. In this study we documented that the drug prescribing patterns for COVID-19 treatment in an outpatient setting from Southern Italy was not supported from current evidence on beneficial therapies for early treatment of COVID-19, thus highlighting the need to implement strategies for improving appropriate drug prescribing in general practice.

Long-term benzodiazepines and z-drug prescribing in Australian general practice between 2011 and 2018: A national study.

Despite reducing benzodiazepine prescribing, benzodiazepine‐involving deaths have substantially increased in Australia. This study aimed to explore patterns in long‐term prescribing of medications (benzodiazepine and z‐drugs [BZD]) used for sleep‐issues/insomnia in Australia to better understand these changes. Open cohort study using de‐identified electronic health records of 1 414 593 adult patients regularly attending 404 Australian general practices from 2011 to 2018 (MedicineInsight). We used logistic regression adjusted for patient and practice characteristics to; (1) estimate long‐term BZD prescribing prevalence (≥3 prescriptions in 6 months) and the associated sociodemographic factors, and (2) Poisson regression to compute annual changes in prescribing rates. Long‐term BZD prescribing changed from 4.4% in 2011 to 5.8% in 2015, remaining relatively stable until 2018 (annual increase +2.5% [95% CI +2.0%;+3.0%]). Long‐term BZD prescribing in any year was up to six times more likely in elderly rather than in younger patients and 30%–43% more prevalent in females, or patients living in or attending a practice located in more disadvantaged areas. The increase was more pronounced among males, adults aged 35–49 years, and individuals living in advantaged areas. The median duration among incident cases decreased from 1183 to 322 days between 2011 and 2017, and was up to 197 days longer among elderly females than males. Despite a slight increase and recent stability in long‐term BZD prescribing, the higher rates and durations among elderly patients, women, or those living in more disadvantaged areas are concerning and highlights the need for interventions that reduce the potential harms of long‐term BZD use in vulnerable groups.

Impact of the COVID-19 Pandemic on Community Antibiotic Prescribing and Stewardship: A Qualitative Interview Study with General Practitioners in England.

The COVID-19 pandemic has had a profound impact on the delivery of primary care services. We aimed to identify general practitioners’ (GPs’) perceptions and experiences of how the COVID-19 pandemic influenced antibiotic prescribing and antimicrobial stewardship (AMS) in general practice in England. Twenty-four semi-structured interviews were conducted with 18 GPs at two time-points: autumn 2020 (14 interviews) and spring 2021 (10 interviews). Interviews were audio-recorded, transcribed and analysed thematically, taking a longitudinal approach. Participants reported a lower threshold for antibiotic prescribing (and fewer consultations) for respiratory infections and COVID-19 symptoms early in the pandemic, then returning to more usual (pre-pandemic) prescribing. They perceived the pandemic as having had less impact on antibiotic prescribing for urinary and skin infections. Participants perceived the changing ways of working and consulting (e.g., proportions of remote and in-person consultations) in addition to changing patient presentations and GP workloads as influencing the fluctuations in antibiotic prescribing. This was compounded by decreased engagement with, and priority of, AMS due to COVID-19-related urgent priorities. Re-engagement with AMS is needed, e.g., through reviving antibiotic prescribing feedback and targets/incentives. The pandemic disrupted, and required adaptations in, the usual ways of working and AMS. It is now important to identify opportunities, e.g., for re-organising ways of managing infections and AMS in the future.

Trends, geographical variation and factors associated with melatonin prescribing in general practices in England: A practice-level analysis.

An overview of melatonin prescribing trends and variation in England is described in this study. Prescription reimbursement data for melatonin in England were extracted from publicly available primary care datasets between 2008-2019. Melatonin prescribing rates, cost and product license status were described over time. Potential factors associated with melatonin prescribing were investigated using Poisson regression. Melatonin prescribing increased from 2.0 to 19.9 per 1000 people between 2008 and 2019. While prescriptions for licensed products increased from 6.5% to 88.2%, spending on unlicensed products was £10 million and accounted for 23.3% of the total prescription cost in 2019. Practices with a higher proportion of children and older people and those serving more deprived patient populations were associated with a higher rate of prescribing (rate ratio = 1.51, 1.66 and 1.59, respectively). Melatonin prescribing in England has increased exponentially over the last decade, with substantial spending on unlicensed products of unknown quality. Patient-level analysis research is needed.

Determinants of drug prescription in general practice in Casablanca: Cross-sectional study

Abstract Background Rational drug prescribing is essential to ensure good disease management and avoid the emergence of drug resistance. However, the decision to prescribe a drug is not only based on the medical knowledge of physicians, but other factors may also influence this decision. We conducted this study to determine the factors that may influence drug prescribing in general practice in Casablanca. Methods A cross-sectional study was conducted in Casablanca (Moulay Rachid and Sidi Bernoussi prefectures) from January to April 2019 among general practitioners in the public and private sectors. The survey was based on the response to a self-administered questionnaire designed and pre-tested by epidemiology laboratory of the Faculty of Medicine and Pharmacy of Casablanca. In addition to a descriptive analysis of the results, a logistic regression analysis was performed to evaluate the factors that could be associated with drug prescription. Results Among 191 general practitioners practicing in the prefectures of Moulay Rachid and Sidi Bernoussi 140 agreed to participate in our study, among which 101 (72.1%) prescribed on average more than two drugs per consultation. In addition to patient-related characteristic: enrolment in medical coverage (OR = 0.1 [0.1; 0.9] if 25-50% of patients had medical coverage), long-term illnesses (OR = 1.73 [1.57; 1.90]); the independent factors associated with this doctor-related prescription were age (OR = 0.23 [0.1; 0.7] over 55 vs. under 40 years), sector of activity (OR = 22.8 [7.4; 70.0] private sector vs public sector), professional seniority (OR = 0.1 [0.01; 0.8] if seniority more than 5 years), and consultation duration (OR = 1.1 [1.09; 1.2]). Conclusions In addition to seniority, duration of consultations, and sector of activity, patient characteristics influence GPs' drug prescription. Key messages The decision to prescribe a drug is influenced by the length of time the GP has been in practice, the duration of consultations and the sector in which he/she works. Patient characteristics influence GPs' drug prescribing.

Safer Prescribing and Care for the Elderly (SPACE): a cluster randomised controlled trial in general practice.

BackgroundSafer prescribing in general practice may help to decrease preventable adverse drug events (ADE) and related hospitalisations.AimTo test the effect of the Safer Prescribing and Care for the Elderly (SPACE) intervention on high-risk prescribing of non-steroidal anti-inflammatory drugs (NSAIDs) and/or antiplatelet medicines and related hospitalisations.Design & settingA pragmatic cluster randomised controlled trial in general practice. Participants were patients at increased risk of ADEs from NSAIDs and/or antiplatelet medicines at baseline. SPACE comprises automated search to generate for each GP a list of patients with high-risk prescribing; pharmacist outreach to provide education and one-on-one review of list with GP; and automated letter inviting patients to seek medication review with their GP.MethodThe primary outcome was the difference in high-risk prescribing of NSAIDs and/or antiplatelet medicines at 6 months. Secondary outcomes were high-risk prescribing for gastrointestinal, renal, or cardiac ADEs separately, 12-month outcomes, and related ADE hospitalisations.ResultsThirty-nine practices were recruited with 205 GPs and 191 593 patients, of which 21 877 (11.4%) were participants. Of the participants, 1479 (6.8%) had high-risk prescribing. High-risk prescribing improved in both groups at 6 and 12 months compared with baseline. At 6 months, there was no significant difference between groups (odds ratio [OR] 0.99; 95% confidence intervals [CI] = 0.87 to 1.13) although SPACE improved more for gastrointestinal ADEs (OR 0.81; 95% CI = 0.68 to 0.96). At 12 months, the control group improved more (OR 1.29; 95% CI = 1.11 to 1.49). There was no significant difference for related hospitalisations.ConclusionFurther work is needed to identify scalable interventions that support safer prescribing in general practice. The use of automated search and feedback plus letter to patient warrants further exploration.

Prescribing antibiotics: the use of diagnostic tests in general practice. A register-based study

Objective To assess (i) the pattern of antibiotic prescribing in Danish general practice, (ii) the use of diagnostic tests [point-of-care (POC) and tests analysed at the hospital laboratory (laboratory tests)], and (iii) the frequency of diagnostic testing in relation to antibiotic prescriptions. Design Retrospective cross-sectional register-based study. Setting General practice in a geographical area of Denmark covering 455,956 inhabitants. Subjects We studied redeemed antibiotic prescriptions and performed diagnostic tests in general practice from 2013 to 2017 among inhabitants in nine selected municipalities. Main outcome measures Frequency of antibiotic courses. Frequency and type of diagnostic testing performed in relation to types of antibiotics. Results A total of 783,252 antibiotic courses were redeemed from general practice with an overall decrease of 19% during 2013–2017. Diagnostic testing increased by 6% during this period. POC tests comprised the majority of performed diagnostic tests (83%) with C-reactive protein (CRP) as the most frequently used test. A 27% increase in the use of laboratory tests was observed. Tests were performed in relation to 43% of all antibiotic courses; most in relation to prescriptions for sulphonamide and trimethoprim (57%) and rarely when prescribing tetracyclines (10%). Conflicting with national guidelines, Danish GPs prescribed fluoroquinolones without performing any kind of diagnostic testing in 48% of the cases. Conclusions This study provides an overview of the use of diagnostic tests in relation to antibiotics and creates basis for further research into the variability between types of antibiotics. The study indicates that there is room for improvement to use diagnostic tests as an aid to promote prudent antibiotic use. KEY POINTS Diagnostic tests (point-of-care or tests analysed at the hospital laboratory), can increase diagnostic certainty and lead to a reduction in antibiotic use in general practice. A decrease in antibiotic courses in general practice in Denmark was observed during 2013–2017, while the use of diagnostic tests increased. A diagnostic test was performed in relation to 43% of antibiotic courses. Only 52% of prescribed fluoroquinolones was related to a diagnostic test, conflicting with national guidelines.

Antibiotic prescribing in Danish general practice in the elderly population from 2010 to 2017

Objective This study aimed to describe prescription of antibiotics to the elderly population in general practice in Denmark from 2010–2017. Design This is a national register-based observational study. Setting General practice, Denmark Main outcome measure The main outcome measure was prescriptions/1,000 inhabitants/day (PrID) in relation to year, age and sex, indication, and antibiotic agent. Subjects In this study, we included inhabitants of Denmark, ≥65 years of age between 01st July 2010–30th June 2017. Results A total of 5,168,878 prescriptions were included in the study. Antibiotic prescriptions decreased from 2.2 PrID to 1.7 (-26.9%, CI95% [-31.1;-22.4]) PrID during the study. The decrease in PrID was most noticeable among 65–74-year-olds (-25%). The ≥85-year-olds were exposed to twice as many PrID than the 65–74-year-olds, but only accounted for 20% of the total use. Urinary tract infection (UTI) was the most common indication for antibiotic prescription and increased with advancing age. The most commonly prescribed antibiotics were pivmecillinam and phenoxymethylpenicillin. Prescribing with no informative indication was present in one third of all cases. Conclusion The prescription of antibiotics in the elderly population in general practice decreased from 2010 to 2017. The oldest age group was exposed twice as frequently to antibiotic prescriptions as the 65–74-year-olds. The smallest reduction was observed for the ≥85-year-olds, suggesting targeting interventions at this group. Key Points High antibiotic use among elderly is well known and studies indicate mis- and overuse within this population. Our study shows. The prescription rate is decreasing within all age groups of the elderly population. The ≥85-year-olds receive twice as many prescriptions/1000/day as the 65–74-years-olds.

Development of an intervention to support the implementation of evidence-based strategies for optimising antibiotic prescribing in general practice

BackgroundTrials show that antimicrobial stewardship (AMS) strategies, including communication skills training, point-of-care C-reactive protein testing (POC-CRPT) and delayed prescriptions, help optimise antibiotic prescribing and use in primary care. However, the use of these strategies in general practice is limited and inconsistent. We aimed to develop an intervention to enhance uptake and implementation of these strategies in primary care.MethodsWe drew on the Person-Based Approach to develop an implementation intervention in two stages. (1) Planning and design: We defined the problem in behavioural terms drawing on existing literature and conducting primary qualitative research (nine focus groups) in high-prescribing general practices. We identified ‘guiding principles’ with intervention objectives and key features and developed logic models representing intended mechanisms of action. (2) Developing the intervention: We created prototype intervention materials and discussed and refined these with input from 13 health professionals and 14 citizens in two sets of design workshops. We further refined the intervention materials following think-aloud interviews with 22 health professionals.ResultsFocus groups highlighted uncertainties about how strategies could be used. Health professionals in the workshops suggested having practice champions, brief summaries of each AMS strategy and evidence supporting the AMS strategies, and they and citizens gave examples of helpful communication strategies/phrases. Think-aloud interviews helped clarify and shorten the text and user journey of the intervention materials. The intervention comprised components to support practice-level implementation: antibiotic champions, practice meetings with slides provided, and an ‘implementation support’ website section, and components to support individual-level uptake: website sections on each AMS strategy (with evidence, instructions, links to electronic resources) and material resources (patient leaflets, POC-CRPT equipment, clinician handouts).ConclusionsWe used a systematic, user-focussed process of developing a behavioural intervention, illustrating how it can be used in an implementation context. This resulted in a multicomponent intervention to facilitate practice-wide implementation of evidence-based strategies which now requires implementing and evaluating. Focusing on supporting the uptake and implementation of evidence-based strategies to optimise antibiotic use in general practice is critical to further support appropriate antibiotic use and mitigate antimicrobial resistance.

519Innovative use of MedicineInsight GP database for applied research on antibiotic prescribing in Western Australia

Abstract Focus of Presentation This project showcases the use of existing general practice (GP) datasets to gain access to large-scale data for epidemiological research. There is limited quantitative research on antibiotic prescribing in Australian GP. The research question involves identifying predictors of antibiotic prescribing not in accordance with national therapeutic guidelines for urinary tract infection (UTI) in Western Australian (WA) GP. This requires large-scale, individual-level data, which is difficult to access in Australia, and in this case could not be achieved without collaboration. Findings Longitudinal records from 52 practices in WA participating in MedicineInsight were analyzed. GP datasets present challenges regarding cleaning, processing and storage. Substantial broad-spectrum antibiotic prescribing was identified in initial episodes of UTI, particularly for children, and not supported by laboratory pathology. Children received broad-spectrum antibiotics 85% of the time, compared to 58% in women. Mixed-effects logistic regression was used to elucidate patient- and consultation-related factors associated with antibiotic prescribing outside of the guidelines. Conclusions/Implications There is evidence of antibiotic prescribing outside of the guidelines for initial presentations of UTI in WA GP. Whilst GP datasets provide insightful information on antibiotic prescribing, it is important to explore these findings with practising clinicians to further understand the drivers behind this behaviour, and this is the next stage of this research. Key messages Collaborative partnerships can facilitate access to rich, large-scale datasets capable of answering important research questions in Australian primary care.

Evaluating the Implementation of a Pilot Quality Improvement Program to Support Appropriate Antimicrobial Prescribing in General Practice.

Inappropriate antimicrobial prescribing contributes to increasing antimicrobial resistance. An antimicrobial stewardship (AMS) program in the form of quality improvement activities that included audit and feedback, clinical decision support and education was developed to help optimise prescribing in general practice. The aim of this study was to evaluate the implementation of this program (Guidance GP) in three general practices in Melbourne, Australia, between November 2019 and August 2020. Thirty-one general practitioners (GPs) participated in the program, with 11 GPs and three practice managers participating in follow-up focus groups and interviews to explore the acceptability and feasibility of the program. Our findings showed that the quality improvement activities were acceptable to GPs, if they accurately fit GPs’ decision-making process and workflow. It was also important that they provided clinically meaningful information in the form of audit and feedback to GPs. The time needed to coordinate the program, and costs to implement the program were some of the potential barriers identified. Facilitators of success were a “whole of practice” approach with enthusiastic GPs and practice staff, and an identified practice champion. The findings of this research will inform implementation strategies for both the Guidance GP program and AMS programs more broadly in Australian general practice, which will be critical for general practice participation and engagement.

Strategies supporting sustainable prescribing safety improvement interventions in English primary care: a qualitative study.

BackgroundWhile the use of prescribing safety indicators (PSI) can reduce potentially hazardous prescribing, there is a need to identify actionable strategies for the successful implementation and sustainable delivery of PSI-based interventions in general practice.AimTo identify strategies for the successful implementation and sustainable use of PSI-based interventions in routine primary care.Design & settingQualitative study in primary care settings across England.MethodAnchoring on a complex pharmacist-led IT-based intervention (PINCER) and clinical decision support (CDS) for prescribing and medicines management, a qualitative study was conducted using sequential, multiple methods. The methods comprised documentary analysis, semi-structured interviews, and online workshops to identify challenges and possible solutions to the longer-term sustainability of PINCER and CDS. Thematic analysis was used for the documentary analysis and stakeholder workshops, while template analysis was used for the semi-structured interviews. Findings across the three methods were synthesised using the RE-AIM (reach, efficacy, adoption, implementation, and maintenance) framework.ResultsForty-eight documents were analysed, and 27 interviews and two workshops involving 20 participants were undertaken. Five main issues were identified, which aligned with the adoption and maintenance dimensions of RE-AIM: fitting into current context (adoption); engaging hearts and minds (maintenance); building resilience (maintenance); achieving engagement with secondary care (maintenance); and emphasising complementarity (maintenance).ConclusionExtending ownership of prescribing safety beyond primary care-based pharmacists, and achieving greater alignment between general practice and hospital prescribing safety initiatives, is fundamental to achieve sustained impact of PSI-based interventions in primary care.

The links between the amount of antipsychotic medication prescribed at GP practice level, local demographic factors and medication selection

AimsTo examine the factors that relate to antipsychotic prescribing in general practices across England and how these relate to cost changes in recent years.BackgroundAntipsychotic medications are the first-line pharmacological intervention for severe mental illnesses(SMI) such as schizophrenia and other psychoses, while also being used to relieve distress and treat neuropsychiatric symptoms in dementia.Since 2014 many antipsychotic agents have moved to generic provision. In 2017_18 supplies of certain generic agents were affected by substantial price increases.MethodThe study examined over time the prescribing volume and prices paid for antipsychotic medication by agent in primary care and considered if price change affected agent selection by prescribers.The NHS in England/Wales publishes each month the prescribing in general practice by BNF code. This was aggregated for the year 2018_19 using Defined Daily doses (DDD) as published by the World Health Organisation Annual Therapeutic Classification (WHO/ATC) and analysed by delivery method and dose level. Cost of each agent year-on-year was determined.Monthly prescribing in primary care was consolidated over 5 years (2013-2018) and DDD amount from WHO/ATC for each agent was used to convert the amount to total DDD/practice.ResultDescriptionIn 2018_19 there were 10,360,865 prescriptions containing 136 million DDD with costs of £110 million at an average cost of £0.81/DDD issued in primary care. We included 5,750 GP Practices with practice population >3000 and with >30 people on their SMI register.Effect of priceIn 2017_18 there was a sharp increase in overall prices and they had not reduced to expected levels by the end of the 2018_19 evaluation year. There was a gradual increase in antipsychotic prescribing over 2013-2019 which was not perturbed by the increase in drug price in 2017/18.RegressionDemographic factorsThe strongest positive relation to increased prescribing of antipsychotics came from higher social disadvantage, higher population density(urban), and comorbidities e.g. chronic obstructive pulmonary disease(COPD). Higher %younger and %older populations, northerliness and non-white (Black and Minority Ethnic (BME)) ethnicity were all independently associated with less antipsychotic prescribing.Prescribing FactorsHigher DDD/general practice population was linked with higher %injectable, higher %liquid, higher doses/prescription and higher %zuclopenthixol. Less DDD/population was linked with general practices using higher %risperidone and higher spending/dose of antipsychotic.ConclusionHigher levels of antipsychotic prescribing are driven by social factors/comorbidities. The link with depot medication prescriptions, alludes to the way that antipsychotics can induce receptor supersensitivity with consequent dose escalation.

Danish GPs' Experiences When Managing Patients Presenting to General Practice with Symptoms of Acute Lower Respiratory Tract Infections: A Qualitative Study.

One of the most common indications for antibiotic prescribing in general practice is acute lower respiratory tract infections (LRTI). This study aimed to explore general practitioners’ (GPs’) considerations and experiences when managing patients with symptoms of an acute LRTI. Individual semi-structured interviews were conducted with seven GPs in the North Denmark Region from January to March 2020. Data were analysed by means of systematic text condensation. The analysis revealed four themes: (1) practicalities of assessing patients with LRTI, (2) assessment of the patient, (3) treatment decisions, and (4) patient expectations. The GPs described having developed individual diagnostic strategies and routines when managing patients with symptoms of an acute LRTI. However, a general assessment of the patient was essential to all the GPs and the diagnosis was seldom based on a single symptom or finding. Most GPs described having great faith in abnormal lung auscultation. The use of C-reactive protein testing served several purposes, such as deciding on the severity of the infection, prescribing antibiotics or not, and as a communicative tool. Diagnostic uncertainty is a driver of antibiotic use and clinical practice might benefit from the development of clinical prediction rules for diagnosing pneumonia.
