Quality improvement in medicines regulation: a retrospective analysis of the Pharmacy Board of Sierra Leone before and during quality management system implementation.

BACKGROUND: National Medicines Regulatory Authorities like the Pharmacy Board of Sierra Leone are responsible for protecting and promoting public health, implementing regulatory standards, and maintaining a supply chain with an assured supply of medical products that are safe, effective, and of good quality. This retrospective study assesses the identification of substandard and falsified medicines, the changes in the functions and key indicators of assessment, and the quality improvement changes of the Pharmacy Board of Sierra Leone. METHODS: Data was obtained from 2013 to 2021 records using a data collection tool to collate and review all relevant information to address the different objectives. All data were sourced from the Department of Quality Assurance and the Department of Enforcement and Narcotics at the Pharmacy Board of Sierra Leone. The review also included, identified substandard and falsified medicines, the World Health Organisation Global benchmarking self-assessment tool, and internal and external audit records of the quality management system of all twelve departments of the Pharmacy Board of Sierra Leone. RESULTS: The study showed marked changes in identifying substandard and falsified medicines by the Pharmacy Board of Sierra Leone during ISO 9001:2015 implementation (2017- 2020) compared to Pre-ISO 9001:2015 implementation (2013- 2016). Critical functions of the Pharmacy Board of Sierra Leone from the assessment of the WHO GBT ML in 2016 and 2021 showed that several indicators had been addressed during ISO 9001:2015 certification with improvement in the level of maturity for the quality management systems and Pharmacovigilance functions. There was also an improvement in identifying non-conformances and a commitment to continuous improvement of processes during ISO 9001:2015 implementation. CONCLUSIONS: This study revealed that regular checks through standard assessment, internal audits, and standard management review processes that generate follow-up actions, timelines, and a commitment to identifying correction, and corrective actions for non-conformances are essential quality improvement tools for the efficient functioning of an institution (Pharmacy Board of Sierra Leone). Our study revealed that commitment to continuous implementation of proper quality management system could significantly improve institutional efficiency, thereby improving service delivery and customer satisfaction.

'She Wanted to Listen to her General Practitioner's Advice ': Exploring and Explaining Antibiotic Prescribing as a Regulatory Encounter.

This article examines the pressing global problem of antimicrobial resistance (AMR), applying motivational posture theory to demonstrate how AMR and the prescribing that drives it can be considered a regulatory challenge. Following an outline of AMR and the threat of the 'superbugs' to which it gives rise, the article assesses the regulatory nature of the 'prescribing encounter' in the primary care setting. It applies both a responsive regulatory lens and motivational posture theory to analyse over 100 narrative accounts of encounters between a general practitioner and a patient. In so doing, the article examines the discursive repertoires and cultural resources available to primary care patients to explain the prescribing encounter and the dynamics within it. It concludes that patients conceive of prescribers as regulatory authorities and prescribing itself as a regulatory encounter. On this basis, the article argues that applying responsive regulatory theory and practice in response to the AMR challenge is likely to find reasonable patient acceptance, offering a new approach to this currently intractable challenge. This article then offers an analysis of what factors indicate patient drift towards defiance of regulatory aims, and what engagement and support encourage a return to cooperation.

Assessing social preferences in reimbursement negotiations for new Pharmaceuticals in Oncology: an experimental design to analyse willingness to pay and willingness to accept.

BACKGROUND: Price negotiations for specialty pharmaceuticals take place in a complex market setting. The determination of the added value of new treatments and the related societal willingness to pay are of increasing importance in policy reform debates. From a behavioural economics perspective, potential cognitive biases and other-regarding concerns affecting outcomes of reimbursement negotiations are of interest. An experimental setting to investigate social preferences in reimbursement negotiations for novel, oncology pharmaceuticals was used. Of interest were differences in social preferences caused by incremental changes of the patient outcome. METHODS: An online experiment was conducted in two separate runs (n = 202, n = 404) on the Amazon Mechanical Turk (MTurk) platform. Populations were split into two (run one) and four (run two) equally sized treatment groups for hypothetical reimbursement decisions. Participants were randomly assigned to the role of a public price regulator for pharmaceuticals (buyer) or a representative of a pharmaceutical company (seller). In run two, role groups were further split into two different price magnitude framings ("real world" vs unconverted "real payoff" prices). Decisions had real monetary effects on other participants (in the role of premium payers or investors) and via charitable donations to a patient organisation (patient benefit). RESULTS: 56 (run one) and 59 (run two) percent of participants stated strictly monotone preferences for incremental patient benefit. The mean incremental cost-effectiveness ratio (ICER) against standard of care (SoC) was higher than the initial ICER of the SoC against no care. Regulators stated lower reservation prices in the "real world" prices group compared to their colleagues in the unconverted payoff group. No price group showed any reluctance to trade. Overall, regulators rated the relevance of the patient for their decision higher and the relevance of their own role lower compared to sellers. CONCLUSIONS: The price magnitude of current oncology treatments affects stated preferences for incremental survival, and assigned responsibilities lead to different opinions on the relevance of affected stakeholders. The design is useful to further assess effects of reimbursement negotiations on societal outcomes like affordability (cost) or availability (access) of new pharmaceuticals and test behavioural policy interventions.

Regulatory and health technology assessment advice on postlicensing and postlaunch evidence generation is a foundation for lifecycle data collection for medicines.

The understanding of the benefit risk profile, and relative effectiveness of a new medicinal product, are initially established in a circumscribed patient population through clinical trials. There may be uncertainties associated with the new medicinal product that cannot be, or do not need to be resolved before launch. Postlicensing or postlaunch evidence generation (PLEG) is a term for evidence generated after the licensure or launch of a medicinal product to address these remaining uncertainties. PLEG is thus part of the continuum of evidence development for a medicinal product, complementing earlier evidence, facilitating further elucidation of a product's benefit/risk profile, value proposition, and/or exploring broader aspects of disease management and provision of healthcare. PLEG plays a role in regulatory decision making, not only in the European Union but also in other jurisdictions including the USA and Japan. PLEG is also relevant for downstream decision-making by health technology assessment bodies and payers. PLEG comprises studies of different designs, based on data collected in observational or experimental settings. Experience to date in the European Union has indicated a need for improvements in PLEG. Improvements in design and research efficiency of PLEG could be addressed through more systematic pursuance of Scientific Advice on PLEG with single or multiple decision makers. To date, limited information has been available on the rationale, process or timing for seeking PLEG advice from regulators or health technology assessment bodies. This article sets out to address these issues and to encourage further uptake of PLEG advice.

Analysing the landscape for prescription to non-prescription reclassification (switch) in Germany: an interview study of committee members and stakeholders.

BACKGROUND: Non-prescription medicines are increasingly used in Germany, aided by prescription-to-non-prescription reclassification (or switch). This study aimed to examine the barriers and enablers to reclassification of medicines in Germany and provide recommendations for change. METHODS: Face-to-face conversational interviews with purposively selected key informants in Germany were conducted in 2017 by a researcher informed in the area. Interviews were transcribed, coded in NVIVO and systematically analysed using a framework approach. RESULTS: Twenty-four interviews were conducted with 32 participants including members of the committee considering reclassifications, and representatives from government, industry, health insurance, academia, and pharmacy, medical, and patients' organisations. A range of enablers and barriers emerged that influence reclassification including effects on the committee and process, or the desire of pharmaceutical companies to pursue reclassifications. Enabling market factors included the large population and a culture of self-medication. Enabling health system factors include the pharmacy-only category. Some pharmacy factors appeared enabling (e.g. a positive experience after reclassifying emergency contraception) while others appeared to hinder reclassification (e.g. insufficient pharmacy practice research). Some medical factors were enabling (e.g. reported waiting times) and others limited reclassification (e.g. opposition to some reclassifications). Some committee and government openness to reclassification and self-medication reportedly enabled reclassification, while conservatism was considered a barrier, particularly for classifications with special conditions for supply such as initial doctor diagnosis or other complexities. Some improvements to the committee constitution and considerations were recommended. Some participants found the reclassification process after the committee recommendation opaque, with opportunity for delays and political interference. Industry factors included both enablers such as capability in reclassification, and barriers, such as a perceived low market potential of some reclassifications, and doubt that some candidates would be approved. A need for more data emerged strongly, both pre-reclassification in applications, and post-reclassification. Many participants saw merit with reclassification in non-traditional areas such as hypertension, diabetes and oral contraception. CONCLUSIONS: Many factors influence reclassification in Germany. Recommended improvements included aspects of the process and committee consideration, and more data collection. Sufficient market exclusivity linked to data collection could aid the generation of evidence to aid committee considerations and encourage more applications of high quality.

Geographical variation in reporting Interstitial Lung Disease as an adverse drug reaction: findings from an European Medicines Agency analysis of reports in EudraVigilance.

PURPOSE: Clinically, interstitial lung disease (ILD) is a heterogeneous group of over 150 respiratory disorders. In the context of its signal evaluation work, the European Medicines Agency's (EMA) Pharmacovigilance Risk Assessment Committee (PRAC) has seen geographic clustering of case reports of ILD from Japan. To explore this further, EudraVigilance (EV), the EMA's database of adverse drug reactions (ADRs), was analysed. The results have been used to inform on implications for pharmacovigilance including signal detection and evaluation activities. METHODS: EV was queried for reports of respiratory ADRs coded using MedDRA for the period 1994-2014 for all medicinal products. Descriptive statistics and non-parametric (chi-square) independence tests were produced to compare reporting of ILD from Japan versus the rest of the world. RESULTS: As of 31 December 2014, there were 26 551 case reports of ILD in EV of which 17 526 (66%) originated in Japan. The reporting rate of ILD for Japan has been consistently higher over the period. The odds that a case report from Japan in EV refers to ILD is OR = 20.7, 95% CI 20.2, 21.3 (p < 0.001), compared to OR = 0.60, 95% CI 0.54, 0.67 (p < 0.001) for pulmonary fibrosis. CONCLUSIONS: A geographic imbalance between Japan and the rest of the world in reporting respiratory ADRs as ILD is confirmed. Consequently, the PRAC has developed approaches to address this in relation to signals of ILD it assesses to allow for more targeted risk minimisation including updates to the product information in the EU setting.

Capacity Assessment of the National Medicines Regulatory Authority in a Low -Income Country.

BACKGROUND: Access to medical products of the required efficacy, quality and safety is essential for everyone's health and wellbeing. To achieve this milestone, every country needs a robust and strong performing National Regulatory Authority (NRA) that is independent and outcome oriented. With the help of the World Health Organization (WHO), the global benchmarking tool is the gold standard used to assess the regulatory capacity of NRAs. OBJECTIVES: This study assessed the capacity of the National Medicines Regulatory Authority in Sierra Leone to perform its regulatory functions. METHODS: This descriptive cross-sectional study used both qualitative and quantitative approaches. A self-administered questionnaire was used for the quantitative approach, and the qualitative aspect consisted of a desk review looking at key regulatory documents such as laws, regulations, policies, guidelines, standard operating procedures and reports. The data collection tool used was the WHO global benchmarking tool (GBT) for "Evaluation of National Regulatory System of Medical Product Version VI. RESULTS: The majority of the participants had a postgraduate degree (60%), and 72% had over 10 years of experience working at the NRA. Out of 251 sub-indicators assessed, 85 (34%) sub-indicators were fully implemented. Of the eight (8) functions assessed, sub-indicators related to clinical trial oversight and vigilance were the most implemented, with 67% and 62%, respectively. Of the 9 indicators assessed, 79% of the sub-indicators that are related to quality and risk management were implemented. The results of this study showed that PBSL operates at maturity level 1. The absence of laws and regulations that give PBSL the mandate to perform its regulatory functions was a major challenge even though other indicators were met. The study reported other challenges toward effective functioning, including but not limited to a lack of sufficient staff, weak enforcement of the sale of medicines and a poorly equipped quality control laboratory.

A Two-Way Proposal for the Determination of Bioequivalence for Narrow Therapeutic Index Drugs in the European Union.

In the European Union, bioequivalence (BE) for narrow therapeutic index (NTI) drugs is currently demonstrated when the 90% confidence interval for the ratio of the population geometric means of the test and reference products for AUC, and in some cases for Cmax, falls within the acceptance range of 90.00% to 111.11%. However, meeting this requirement results in an increased difficulty of demonstrating BE and a need for clinical trials with larger subject sample sizes, especially for medium-to-high variability drugs. To address this challenge, a scaled average BE based on the reference product within-subject variability for narrowing the acceptance range of NTI drugs was recently proposed. However, this approach showed increased type I error (T1E), especially close to the cut-off point between the unscaled and scaled portions of the method. Based on simulations, this limitation can be overcome by predefining the protocol the path to be followed: either the fixed 90.00-111.11% acceptance range approach or the previously proposed scaled average BE approach with a slight adjustment of the one-sided significance level α to 0.042 for a 2 × 3 × 3 partial replicate design and without a lower cut-off point. This results in a mixed approach allowing to reduce the sample size whilst not inflating the T1E.

WHO-listed authorities (WLA) framework: transparent evidence-based approach for promoting regulatory reliance towards increased access to quality-assured medical products.

Background: Increased global access to safe, effective and quality-assured medical products remains a primary goal for the full realization of the World Health Assembly Resolution WHA 67.20 on regulatory systems strengthening for medical products as well as target 3.8 of the Sustainable Development Goals (SDG). To promote the development of efficient regulatory systems, the WHO introduced the Global Benchmarking Tool (GBT) in 2016, upon which the WHO-Listed Authority (WLA) framework was later established. This study aimed to appraise the development of the WLA framework across various phases while highlighting its achievements, challenges, and areas for improvement. Methods: An exploratory study design using a qualitative approach was used to gather information from relevant documents as well as views and experiences from purposefully selected participants from diverse backgrounds. Data was collected using a combination of desk reviews and In-depth one-to-one or small group interviews employing semi-structured interview guides with open-ended questions. Data was analysed using an inductive thematic analysis approach. Results: The leading role of the WHO was noted in developing and implementing essential documents and mediating consultative processes among stakeholders. The framework was revealed to bring an evidence-based, inclusive, and transparent approach to recognizing regulatory authorities (RAs) operating at the highest standards of performance. The framework was anticipated to promote regulatory reliance among all RAs, the WHO's prequalification programme, and procurement agencies. Furthermore, remarkable progress towards WLA listing was noted among transitional WLAs including the Stringent Regulatory Authorities (SRAs). Challenges related to the availability of resources, resistance to change, and complexity were associated with the framework. Conclusion: The study provides a well-rounded view with regard to the roles of the WHO, Member States and other stakeholders in establishing and operationalizing the WLA framework. Furthermore, evaluating the performance and possible WLA designation of RAs operating at international regulatory standards underscores its high relevance in contributing to public health globally. Maintenance along with timely addressing of highlighted next steps to improve the framework particularly in creating better understanding, more communication, and coordination are highly encouraged.

A provisional evaluation of Australia's medical cannabis program.

In 2016, the Australian Government legislated to allow cannabis to be prescribed to patients as an unapproved medicine under the special access provisions of the Therapeutic Goods Act. This paper compares the Australian regulatory approach with other national approaches, outlines the main provisions of the Special Access Scheme for medical cannabis, describes how the program has evolved since 2017, includes an analysis of adverse events reported to the Therapeutic Goods Administration, and discusses the barriers that remain for patients who wish to access medical cannabis. It assesses how well the Australian program has addressed the challenges of providing patients with easier access to medical cannabis while ensuring that high-quality products are used safely and effectively under medical guidance.

Registration of essential medicines in Kenya, Tanzania and Uganda: a retrospective analysis.

OBJECTIVES: To audit national drug registers (NDRs) in Kenya, United Republic of Tanzania and Uganda with respect to national Essential Medicine Lists (EMLs) and to conduct an analysis of highly registered products including a sub-analysis of highly registered antimicrobial products. DESIGN: Retrospective analysis of registration of essential medicines and medicinal products on NDRs as of February 2018. SETTING: Not applicable. PARTICIPANTS: None. MAIN OUTCOME MEASURES: Registration status of essential medicines by country, essential medicine status of registered products by country and medicines with more than 50 registrations across all three countries. RESULTS: A high proportion of essential medicines are not registered: Kenya 28% (175/632), United Republic of Tanzania 50% (400/797) and Uganda 40% (266/663). Of registered products on the NDRs, more than half are not essential: Kenya 71% (4350/6151), United Republic of Tanzania 64% (2278/3590) and Uganda 58% (2268/3896). When the three NDRs were combined, there were 42 medicines with over 50 registered products, accounting for 30% (4153/13637) of products, many of which were non-essential. CONCLUSIONS: Non-registration of essential medicines is a barrier to availability. Over-registration of medicines, particularly non-essential medicines, diverts regulatory resources towards registering non-priority and, sometimes, clinically sub-optimal medicines. The East African Community Medicines Registration Harmonization Project has the potential to improve access to key medicines if registration of essential medicines is prioritised and registration of non-essential medicines is restricted.

Prediction of therapeutic value of new drugs approved by health Canada from 2011-2020: A cross-sectional study.

Objectives: To examine whether a combination of three characteristics of new drugs - review type, outcome of premarket trials (surrogate or clinical) and first-in-class is associated with significant therapeutic value. Design: Cross-sectional analysis of new drugs approved by Health Canada from January 1, 2011 to December 31, 2020. Setting: Canada. Participants: New drugs approved by Health Canada for which therapeutic evaluations, trial outcomes and first-in-class status was available. Main outcome measures: Distribution of therapeutic value (major, moderate, little to no) depending on how many of the three characteristics were present for each drug. Results: Health Canada approved 340 drugs of which 243 had data available for analysis. If all three characteristics were present 10 out of the 20 drugs had a major therapeutic rating. Conversely if none were present only 2 drugs out of 37 had a major therapeutic rating. Conclusion: This study introduces a new evaluation method for determining whether new drugs will have major therapeutic value that appears to be more successful than relying only on the type of review that drugs receive.

Evaluation of a Proposed Approach for the Determination of the Bioequivalence Acceptance Range for Narrow Therapeutic Index Drugs in the European Union.

Bioequivalence (BE) of products containing narrow therapeutic index (NTI) drugs in the European Union is currently established by demonstrating that the 90% confidence interval for the ratio of the population geometric means of the test compared to the reference product's AUC, and in certain cases Cmax, is included within the tighter acceptance range of 90.00−111.11%. An alternative criterion, consisting of narrowed limits based on the within-subject variability of the reference product, was recently proposed. Its performance for a three-period partial replicate design was tested by simulation in terms of power to show BE, type I error (T1E) and sample size requirements. A new condition, a constraint on the test-to-reference geometric mean ratio (cGMR) to be contained within the range of 90.00−111.11%, was also tested. The probability of showing BE when the products differ more than 10% was increased, but only if the reference product's within-subject variability was moderate-to-high. The inclusion of the additional cGMR limited this. An increase in the T1E (<7%) was observed. The inclusion of the additional cGMR did not change the highest inflation of the T1E. Finally, a significant sample size reduction was observed and the inclusion of the cGMR usually did not increase the required sample size.

Health horizons: Future trends and technologies from the European Medicines Agency's horizon scanning collaborations.

In medicines development, the progress in science and technology is accelerating. Awareness of these developments and their associated challenges and opportunities is essential for medicines regulators and others to translate them into benefits for society. In this context, the European Medicines Agency uses horizon scanning to shine a light on early signals of relevant innovation and technological trends with impact on medicinal products. This article provides the results of systematic horizon scanning exercises conducted by the Agency, in collaboration with the World Health Organization (WHO) and the European Commission's Joint Research Centre's (DG JRC). These collaborative exercises aim to inform policy-makers of new trends and increase preparedness in responding to them. A subset of 25 technological trends, divided into three clusters were selected and reviewed from the perspective of medicines regulators. For each of these trends, the expected impact and challenges for their adoption are discussed, along with recommendations for developers, regulators and policy makers.

Regulatory policy and pharmaceutical innovation in the United Kingdom after Brexit: Initial insights.

Brexit was presented as an opportunity to promote innovation by breaking free from the European Union regulatory framework. Since the beginning of 2021 the Medicines and Healthcare products Regulatory Agency (MHRA) has operated as the independent regulatory agency for the United Kingdom. The MHRA's regulatory activity in 2021 was analyzed and compared to that of other international regulatory bodies. The MHRA remained reliant on EU regulatory decision-making for novel medicines and there were significant regulatory delays for a small number of novel medicines in the UK, the reasons being so far unclear. In addition, the MHRA introduced innovation initiatives, which show early promise for quicker authorization of innovative medicines for cancer and other areas of unmet need. Longer-term observation and analysis is needed to show the full impact of post-Brexit pharmaceutical regulatory policy.

The Pivotal Role of Quality Technical Structures for Clinical Trials Oversight in the Achievement of Long-Term Capacity Strengthening Outcomes.

Background: Development of safe and efficacious medicines in many sub-Sahara African countries remains hampered due to fragmented health research infrastructure and ineffective regulatory oversight. To boost the latter in the area of Clinical Trials (CT) Oversight (CTO), many international programs and Regional Centers for Regulatory Excellence (RCORE) initiatives offer various trainings to help strengthen human resource capacity. Here, we aimed at evaluating the training outcomes (at home-institution level) of sponsored fellows for one of such capacity strengthening interventions; a measure that is less often reported and thus remains poorly understood. Method: The Global Health Protection Programme's VaccTrain project sponsored nine regulatory staff from eight National Medicines Regulatory Authorities (NMRAs) in sub-Saharan Africa for the RCORE CT Training Fellowship by FDA Ghana in a particular year. Using a systematized evaluation framework based on the theory of change, we assessed the individual- and NMRA-level achievement of pre-defined training outcomes. For this purpose, data was collected at pre-training and at short- and long-term evaluation time-points using a survey instrument. Results: At pre-training, our data revealed existence of differential expectations and orientations among the training participants, thus providing an early indication of potential distinctive patterns in achievement of desired training outcomes. In a short-term post-training follow-up evaluation, a two-group clustering of fellows based on the achievement of training outcomes where only one group (representing 44%) reported achievement of CTO-related outcomes was observed. At this time-point, achievement of training outcomes was associated with the vibrancy of CT activity and existence of a comprehensive technical structure for CTO. In a further long-term follow-up evaluation, our data revealed a successful achievement of CTO-related individual- and/or institutional-level outcomes in all but one fellow. Here again, availability of a robust technical structure for CTO (and perhaps fellow affiliation/selection)-but not CT vibrancy-showed a trend of temporal association with achievement of training outcomes. Conclusion: Given the pivotal role operational structures of international standards at home institutions play in translating training-acquired knowledge into measurable CTO-related outcomes, we encourage that capacity strengthening projects aimed at achieving health-related targets of Sustainable Development Goals adopt an approach built on this foundation.

Sponsorship of Australian and New Zealand medical societies by healthcare companies: an observational study.

Objectives: To examine sponsorship of Australian and New Zealand medical societies by healthcare companies and whether societies have policies to deal with conflicts of interest. Design: Cross-sectional study conducted in March 2022. Setting: Australia and New Zealand. Participants: Medical societies in both countries. Main outcome measures: The percent of medical societies that list sponsorship from healthcare companies on either their home webpages or the webpages of their annual meetings and/or that issue prospectuses to potential sponsors. The percent of societies with sponsorship that also have policies about their interactions with their sponsors. Whether societies feature their sponsors' logos on their webpages and have hyperlinks to sponsors' webpages and what percent of societies' annual revenue comes from sponsorships. Results: Ninety-two medical societies were identified. Sixty-two had healthcare company sponsorship and 10 of the societies with sponsorship had policies to deal with interactions with their sponsors. Fifty-four societies displayed the logos of their sponsors on their home webpages and/or the webpages of their annual meetings. Only 6 societies provided enough information to calculate what percent of their revenue comes from sponsorships. For 5 of the 6 the percent was well below 50%. Conclusions: The acceptance of sponsorships from healthcare companies by Australian and New Zealand societies is common and few societies have policies to deal with these relationships. In general, societies appear to get only a small percent of their annual revenue from sponsorships.

The new Veterinary Medicines Regulation: rising to the challenge.

This article focuses on the new Veterinary Medicines Regulation, which is applicable across all Member States of the European Union, including Ireland, from 28 January 2022. From this date, prophylactic use of antimicrobials (AMs) in groups of animals is banned, metaphylactic use in groups of animals is restricted, and certain AMs are reserved for humans only. In the Irish dairy industry, as elsewhere, successful implementation of the Regulation will require a high level of mastitis control across all herds, and measures to support high standards in antibiotic stewardship. National actions will be critical, to support optimal mastitis control throughout the national herd. For private veterinary practitioners (PVPs), the Regulation will lead to specific prescribing changes, including the requirement to shift from blanket to selective dry cow therapy. Further, prescribing choices will need to be guided by the categorisation for AMs developed by the European Medicines Agency (EMA). More broadly, the Regulation requires a fundamental shift in thinking both in terms of AM usage and of the role of the PVP. Given the close association between mastitis control and intramammary AM stewardship, it is imperative that prescribing and mastitis control decisions are made concurrently. A herd health approach will be critical, within a Client-Patient-Practice Relationship as outlined by the Veterinary Council of Ireland. On those farms with sub-optimal mastitis control, mastitis issues need to be sustainably resolved. A detailed farm investigation by the PVP, in partnership with the farmer and other milk quality professionals, is essential, to understand the epidemiology and on-farm drivers of mastitis, to develop farm-specific action plans, and to facilitate ongoing monitoring of progress. It is vital that PVPs provide leadership, with the provision of a holistic, herd health approach to inform both prescribing and mastitis control decisions in herds under their care.

Up-scheduling and codeine supply in Australia: analysing the intervention and outliers.

BACKGROUND AND AIMS: Over-the-counter codeine products were up-scheduled to prescription only in Australia from February 2018. This trend study aimed to identify changes in codeine supply before and after the February 2018 implementation. DESIGN, SETTING AND CASES: Time-series regression analysis of monthly medicine supplies in Australia from 2014 to 2018. The February 2018 up-scheduling was pre-specified as the intervention; outlier analysis was used to detect automatically sudden unexpected changes before February 2018. MEASUREMENTS: Per-capita supplies based on national data for pharmaceutical wholesales and population exposure. Weight of supplies in milligrams for low-dose codeine (≤ 15 mg per tablet or ≤ 1.92 mg per ml, originally sold over the counter but up-scheduled after February 2018), high-dose combination codeine (30 mg per tablet, prescription only throughout the study period) and all codeine. FINDINGS: Several level shifts in supply occurred during the 5 years, led by one of -4.4% [95% confidence interval (CI) = -6.6 to -2.1%] in high-dose codeine in 2015, followed by shifts in low-dose codeine of -40.0% (CI = -46.9 to -32.3%) and -82.2% (CI = -84.3 to -79.9%), respectively, before and after February 2018. High-dose codeine supply increased by 4.4% (CI = 1.8-7.1%) immediately after up-scheduling. Also detected were transient increases and decreases in 2016 and 2017. Compared with pre-2015 levels, the February 2018 up-scheduling was associated with reductions of 45.7% (CI = 43.2-48.0%) and 89.3% (CI = 87.9-90.6%), respectively, in all and low-dose codeine supply but no change in high-dose codeine supply. The level shifts and transient changes were located around various regulatory activities, including public announcements and expert advisory meetings on up-scheduling. CONCLUSION: Up-scheduling of over-the-counter codeine products in Australia in 2018 appears to have been associated with a near halving of Australia's national codeine supply. The transition occurred in multiple forms and phases.

Recurrence of endometrial cancer in a hysterectomised patient treated with tamoxifen for breast cancer: a case report.

Tamoxifen exposure is a recognised risk for primary endometrial cancer. This case serves as a reminder to meticulously check the past medical history and inform patients of the risk-benefit of treatment as part of a shared-decision making process.
