Budget impact analyses (BIAs) are an essential component of the economic evaluation of new oncological and haematological drugs, and are increasingly required by health authorities in many countries as part of the pricing and reimbursement process. This article aims to provide updated guidance on the methodology for performing such analyses. In a BIA, the resource consumption in the reference scenario (before the new drug is introduced) is always compared with the resource consumption in the future scenario (after the new treatment is commercialized). The most important parts of a BIA include calculating the number of the existing patient population, the current mix of treatments and the expected mix after the coming of the new drug, the cost of the treatment mixes and other changes in cancer-related costs. The BIA's data sources should be drawn from the best available published evidence, such as clinical trials, observational studies, local epidemiological information, cost databases and expert opinion. Where possible, the decision maker's population and calculations for other parameter estimations should also be included. A deterministic analysis and a scenario sensitivity analysis should be carried out in every BIA. The BIA report must provide details of resource consumption and associated costs in the reference scenario and the future scenario. The difference between the 2 scenarios will represent the budget impact of introducing a new drug to the market.</p>","PeriodicalId":9251,"journal":{"name":"British journal of clinical pharmacology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145191012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of feedback for computer-based assessment-now increasingly prevalent in higher education-remains relatively underexplored, particularly for pharmacology education. The growing momentum of curricular evolution in pharmacology education presents a timely opportunity to appraise and improve feedback practices in computer-based assessment within the discipline. While there is extensive literature which outlines the principles of effective feedback, there is not a universal model we can apply with consistently positive outcomes. This review explores how empirical evidence can inform the development of effective feedback for use in computer-based assessment. Drawing on findings from multiple meta-analyses and primary research exploring elements of feedback design from across disciplines, this review confirms that elaborate feedback is more effective than corrective feedback alone. However, to support students to develop metacognitive skills for life-long learning, feedback should be tailored to the characteristics of the learner with dialogic support necessary to optimize impact. It is also clear that a key prognostic indicator of successful feedback for performance and satisfaction is clear links to goals and standards. This review argues for feedback for computer-based assessment to go beyond that which is efficient. Instead, it should be constructively aligned with clear goals, and be learner-centred and dialogic to ensure we support the development of reflective and capable graduates of pharmacology education.</p>","PeriodicalId":9251,"journal":{"name":"British journal of clinical pharmacology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145191175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
