However, it is now often conflated with use of the first name of healthcare professionals, both in introductions and on name badges, which can cause confusion about names, titles, and roles. The “Hello, my name is” campaign needs updating. Names matter for patients, but introductions using first names alone are insufficient. Introductions and badges should include a healthcare professional’s full name, title, and role. Healthcare delivery has diversified, so role recognition is more difficult and important than ever.

Context and current practice Colorectal cancer (CRC), the third most common cancer and the second leading cause of cancer-related death globally, typically arises from adenomatous polyps. Detection and removal of polyps during colonoscopy can reduce the risk of cancer. CADe systems use artificial intelligence (AI) to assist endoscopists by analysing real-time colonoscopy images to detect potential polyps. Despite their increasing use in clinical practice, guideline recommendations that carefully balance all patient-important outcomes remain unavailable. In this first iteration of a living guideline, we address the use of CADe at the level of an individual patient. Evidence Evidence for this recommendation is drawn from a living systematic review of 44 randomised controlled trials (RCTs) involving more than 30 000 participants and a companion microsimulation study simulating 10 year follow-up for 100 000 individuals aged 60-69 years to assess the impact of CADe on patient-important outcomes. While no direct evidence was found for critical outcomes of colorectal cancer incidence and post-colonoscopy cancer incidence, low certainty data from the trials indicate that CADe may increase positive endoscopy findings. The microsimulation modelling, however, suggests little to no effect on CRC incidence, CRC-related mortality, or colonoscopy-related complications (perforation and bleeding) over the 10 year follow-up period, although low certainty evidence indicates CADe may increase the number of colonoscopies performed per patient. A review of values and preferences identified that patients value mortality reduction and quality of care but worry about increased anxiety, overdiagnosis, and more frequent surveillance. Recommendation For adults who have agreed to undergo colonoscopy, we suggest against the routine use of CADe (weak recommendation). How this guideline was created An international panel, including three patient partners, 11 healthcare providers, and seven methodologists, deemed by MAGIC and The BMJ to have no relevant competing interests, developed this recommendation. For this guideline the panel took an individual patient approach. The panel started by defining the clinical question in PICO format, and prioritised outcomes including CRC incidence and mortality. Based on the linked systematic review and microsimulation study, the panel sought to balance the benefits, harms, and burdens of CADe and assumed patient preferences when making this recommendation Understanding the recommendation The guideline panel found the benefits of CADe on critical outcomes, such as CRC incidence and post-colonoscopy cancer incidence, over a 10 year follow up period to be highly unce","PeriodicalId":22388,"journal":{"name":"The BMJ","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a focus could lead to challenges in application and loss of reliability of instruments. To deal with these shortcomings, the Risk Of Bias instrument for Use in SysTematic reviews-for Randomised Controlled Trials (ROBUST-RCT) was created—a rigorously developed, simply structured, and user friendly instrument for assessing risk of bias of randomised controlled trials included in systematic reviews. This paper describes the development of ROBUST-RCT and provides associated documents and a manual of instructions. Although systematic reviews of randomised controlled trials provide the best evidence for the effects of healthcare interventions,1 flaws in trial design and conduct may result in biased estimates of effects, and hence misleading conclusions.2 As a result, risk of bias assessment of randomised controlled trials has become an essential step in the systematic review process. Furthermore, risk of bias represents one domain in the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system of rating certainty of evidence, and trial limitations resulting in risk of bias may lead authors of systematic reviews to rate down the certainty of evidence.34 Although many instruments for assessing risk of bias in randomised controlled trials are available,5 most have important limitations. A systematic survey found that existing instruments often include items that do not deal with risk of bias.5 To be suitable for use in systematic reviews, risk of bias instruments should include only items that deal with risk of bias problems rather than other GRADE domains.3 The most popular and rigorously developed instruments include those offered by the Cochrane Collaboration. The first Cochrane risk of bias instrument6 included an “unclear” response option that …","PeriodicalId":22388,"journal":{"name":"The BMJ","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Katharine Lang asks if these can safely make up the shortfall In the UK more than 3 in every 1000 people are taking glucagon-like peptide-1 (GLP-1) agonist drugs, says Kevin McCarroll, consultant physician and geriatrician at St James Hospital, Dublin.1 Depending on the region, 77-179 in 100 000 people are using the leading GLP-1 drug semaglutide (Ozempic for type 2 diabetes, Wegovy for obesity), he says.1 And these are just the official prescribing figures—anecdotal evidence suggests many are purchasing the drugs from unofficial sources. Growing evidence of the drugs’ efficacy for weight loss2 is fuelling demand worldwide. The number of patients in the US approved for GLP-1 agonist treatment for obesity rose from 190 000 a month in 2021 to 1.8 million in 2024.3 Analysis of the US market shows that 5.2% of women and 4.2% of men with obesity are being prescribed the drugs, although access varies. “The global supply shortage seen in 2024 was at least partly because of a surge in off-label prescriptions for semaglutide for weight loss,” says Eamon Laird, assistant lecturer in nutritional science at ATU Sligo in Ireland. He added that use of the drug for weight loss by people without obesity and those who do not have any weight related health problems is exacerbating the situation. “Manufacturers are trying to upscale production, but it’s taking time. This is a global shortage with global demand. Similar shortages are reported in Ireland, the UK, the EU, and the US.” To try to increase availability the US Food and Drug Administration (FDA) has allowed pharmacies to manufacture and sell “compounded” versions of the drugs—these are copies of approved drugs or drugs under patent, allowed when licensed drugs are …","PeriodicalId":22388,"journal":{"name":"The BMJ","volume":"183 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143695557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
