Purpose Sharing and developing digital educational resources and open educational resources has been proposed as a way to harmonize and improve clinical pharmacology and therapeutics (CPT) education in European medical schools. Previous research, however, has shown that there are barriers to the adoption and implementation of open educational resources. The aim of this study was to determine perceived opportunities and barriers to the use and creation of open educational resources among European CPT teachers and possible solutions for these barriers. Methods CPT teachers of British and EU medical schools completed an online survey. Opportunities and challenges were identified by thematic analyses and subsequently discussed in an international consensus meeting. Results Data from 99 CPT teachers from 95 medical schools were analysed. Thirty teachers (30.3%) shared or collaboratively produced digital educational resources. All teachers foresaw opportunities in the more active use of open educational resources, including improving the quality of their teaching. The challenges reported were language barriers, local differences, lack of time, technological issues, difficulties with quality management, and copyright restrictions. Practical solutions for these challenges were discussed and include a peer review system, clear indexing, and use of copyright licenses that permit adaptation of resources. Conclusion Key challenges to making greater use of CPT open educational resources are a limited applicability of such resources due to language and local differences and quality concerns. These challenges may be resolved by relatively simple measures, such as allowing adaptation and translation of resources and a peer review system.

The ChAdOx1 nCoV‐19 vaccine has been associated with increased risk of thrombosis. Understanding of the management of these rare events is evolving, and currently recommended treatments include human normal immunoglobulin and nonheparin anticoagulation such as direct oral anticoagulants. Our report describes three consecutive patients presenting to a London teaching hospital with vaccine‐induced thrombotic thrombocytopenia (VITT), also referred to as vaccine‐induced prothrombotic immune thrombocytopenia. The patients ranged in age from 40 to 54 years and two had no known previous medical comorbidities. Two patients had cerebral venous sinus thrombosis and one had a deep vein thrombosis. Two were treated with anticoagulation, one with oral rivaroxaban and the other with an intravenous argotraban infusion that was later converted to oral apixaban. One patient received three doses of human normal immunoglobulin and 5 days of therapeutic plasma exchange. This case series may be used to improve understanding of the clinical course and management of VITT. [ABSTRACT FROM AUTHOR]

Wilson, Kurt (University of Manchester, Manchester, United Kingdom) Improvement and harmonization of European clinical pharmacology and therapeutics (CPT) education is urgently required. Because digital educational resources can be easily shared, adapted to local situations and re‐used widely across a variety of educational systems, they may be ideally suited for this purpose Methods With a cross‐sectional survey among principal CPT teachers in 279 out of 304 European medical schools, an overview and classification of digital resources was compiled. Results Teachers from 95 (34%) medical schools in 26 of 28 EU countries responded, 66 (70%) of whom used digital educational resources in their CPT curriculum. A total of 89 of such resources were described in detail, including e‐learning (24%), simulators to teach pharmacokinetics and/or pharmacodynamics (10%), virtual patients (8%), and serious games (5%). Together, these resources covered 235 knowledge‐based learning objectives, 88 skills, and 13 attitudes. Only one third (27) of the resources were in‐part or totally free and only two were licensed open educational resources (free to use, distribute and adapt). A narrative overview of the largest, free and most novel resources is given. Conclusion Digital educational resources, ranging from e‐learning to virtual patients and games, are widely used for CPT education in EU medical schools. Learning objectives are based largely on knowledge rather than skills or attitudes. This may be improved by including more real‐life clinical case scenarios. Moreover, the majority of resources are neither free nor open. Therefore, with a view to harmonizing international CPT education, more needs to be learned about why CPT teachers are not currently sharing their educational materials.

On 3 September 2012, the UK Medicines and Healthcare Products Regulatory Agency (MHRA) notified healthcare professionals of immediate changes to the intravenous acetylcysteine license terms, altering the treatment pathway for paracetamol poisoning. We sought to evaluate awareness of this amongst healthcare professionals.We surveyed doctors, nurses and pharmacists in the 1-12 week period following the implementation date.Forty-four individuals completed the survey in paper form (response rate 86%) and 220 in electronic form (response rate unknown). The resulting sample of 264 individuals was drawn from 41 institutions, and included 143 doctors, 58 pharmacists and 50 nurses. Of these individuals, 157 (59%) were aware of the changes, and 133 (50%) had adopted them in practice. Awareness differed between healthcare professions (P = 0.001) and specialties (P = 0.002). For respondents aware of the changes, the main sources of information were alerts issued internally (reported by 57%), from the MHRA (25%) and from other professional bodies (24%). The proportion of individuals who reported receiving practical implementation instructions (e.g. a protocol) was higher among respondents who had changed their practice than for those who had not (86 vs. 25%, respectively; P0.001).Less than two-thirds of healthcare professionals in specialties managing patients with paracetamol poisoning were aware of important changes to its treatment pathway in the 12 weeks after they took effect, and only half had adopted them in practice. Alternative communication strategies should be explored to improve dissemination of similar information from the MHRA and other medicines regulators in the future.

Holta, Christopher T. and Hitchings, Andrew W.
- Abstract
Drug causes of metabolic acidosis are numerous and their mechanisms are diverse. Broadly, they can cause metabolic acidosis with either a normal anion gap (e.g. drug-induced renal tubular acidosis) or an elevated anion gap (e.g. drug-induced lactic acidosis or pyroglutamic acidosis). This review describes the drugs that can cause or contribute to metabolic acidosis during therapeutic use, the mechanisms by which this occurs, and how they may be identified in practice.

It is important to monitor drug therapy because the effects of a particular drug regimen can vary significantly between individuals. Wherever possible, therapeutic effect should be monitored using a clinical endpoint (i.e. a measure that directly reflects how the patient feels, functions or survives). In practice, it is often not feasible to use a clinical endpoint to guide therapy, particularly for preventive treatments. The next best option is to use a surrogate endpoint: a measure that changes so as to predict whether the clinical endpoint will be achieved. For a few drugs, neither a clinical nor a surrogate endpoint is available. In these instances, if the drug has a narrow therapeutic index and there is a predictable relationship between its concentration and its effects, it may be appropriate to measure its concentration in the blood. This article discusses approaches to monitoring drug therapy using clinical and surrogate endpoints, and plasma concentration monitoring. Specific guidance is provided for plasma concentration monitoring of digoxin, gentamicin, vancomycin, phenytoin, lithium and theophylline. [ABSTRACT FROM AUTHOR]

SCIENTIFIC observation , *OBSTRUCTIVE lung diseases , *HOSPITAL admission & discharge , *DISEASE exacerbation - Abstract
Background Despite currently available treatment, 13.9% of patients admitted to hospital for exacerbations of chronic obstructive pulmonary disease (COPD) die within 3 months, and fewer than half survive 5 years. Most of the cost of COPD to the UK health service, which approaches £1bn/year, is associated with the treatment of exacerbations. There is clearly a need to improve outcomes of patients admitted to hospital for exacerbations, and yet relatively few research studies attempt to recruit patients specifically during this phase of their illness. Methods During 2010-2011, two studies were conducted within our institution recruiting patients hospitalised for COPD exacerbations. One was an observational study with relatively broad entry criteria; the other was a randomised, controlled, interventional trial with more stringent entry criteria (ISRCTN66148745). We analysed the screening logs to identify eligibility rates and potential barriers to recruitment, and to provide a guide for researchers on the feasibility of proposed studies in similar populations elsewhere. Results In the 12-month period commencing March 2010, 172 patients were screened for entry to the observational study. In the period January to June 2011, a further 72 patients, not included in the first study, were screened for entry into the clinical trial. Significant exclusion criteria for each study protocol for were identified; for comparison, these are represented across organ systems (Abstract P216 table 1). 29% of those screened for the observational study were eligible for inclusion and 11% for the clinical trial. The clinical trial identified more renal and metabolic conditions, reflecting their particular relevance to experimental drug administration. The observational study identified more physical factors, such as frailty, which may limit patients' ability to engage with observational research tasks. Conclusion Patients hospitalised for COPD exacerbations are heterogeneous and have significant and diverse co-morbidities which may limit their eligibility for research studies. In view of this, broad entry criteria are necessary to ensure that studies in this population are feasible. With careful design, such studies will be pivotal in driving improved treatment and outcomes among these patients who, despite their poor prognosis, presently receive disproportionately little research attention.

Background Approximately 10% of patients with chronic obstructive pulmonary disease (COPD) have co-existing diabetes mellitus, conferring an adverse prognosis. Metformin is a valuable first-line treatment for diabetes. However, its rare association with lactic acidosis limits its use among patients at risk of hypoxia. This may deter some practitioners from prescribing it to patients with significant co-existing COPD. It is unknown whether the benefits of metformin outweigh its risks in this context. We therefore sought to determine the effects of metformin on survival and length of stay in a high-risk cohort of diabetic patients hospitalised for COPD exacerbations. Methods The medical records of diabetic patients hospitalised for COPD were reviewed retrospectively. Length of hospital stay and all-cause mortality were compared according to the presence or absence of metformin therapy. Results 130 patients were included, of whom 51 (39%) were prescribed metformin. Patients on metformin had a shorter hospital stay (median 7 vs 9 days respectively; p=0.004). Survival at 90 days was significantly better in the metformin group than in the non-metformin group (94% vs 78% respectively; p=0.015; Abstract P259 figure 1 inset). This persisted over the longer term, with overall median (95% CI) survival of 5.2 years (4.3 to 6.1) in the metformin group and 2.2 years (1.0 to 3.3) in the non-metformin group (HR 0.57; 95% CI 0.35 to 0.94; Abstract P259 figure 1). This difference remained significant in a multivariate model, adjusting for potential confounding effects of age, weight, acute illness severity (APACHE-II score) and comorbidity burden. Among patients prescribed metformin, vs those not, the median (IQR) plasma lactate concentration was 1.45 mmol/l (1.10-2.05) vs 1.10 mmol/l (0.80-1.50), respectively (p=0.012). Conclusion Diabetic patients hospitalised for COPD exacerbations who were prescribed metformin were discharged earlier and survived longer than those not prescribed metformin. Lactate concentration was higher among patients on metformin, although the difference was small. Our results suggest that the drug's benefits may outweigh its rare association with lactic acidosis. Whether this reflects beneficial effects on diabetes- or COPD-related endpoints; other associated conditions; or the effect of unmeasured confounders, is unknown. We are now investigating this within the context of a randomised controlled trial (ISRCTN66148745). [ABSTRACT FROM AUTHOR]
