This article discusses strategies and challenges in implementing evidence-based clinical guidelines, including the tenets of evidence-based medicine, hierarchy of evidence, and the AGREE-II checklist. It also explores the difficulties and benefits of guideline implementation, conflicts of interest, types of knowledge, and practical considerations. The text delves into case studies like the Fujii story and offers insights into improving the transfer of research into practice.

Hierarchy of evidence Systematic review of RCTs A single RCT Observational studies Case series and reports
Two caveats…….. Applicability of RCTs Quality of evidence: large observational study vs. a small RCT
Gap between need from public health perspective and what can be afforded
Clinical guidelines The WHO definition: ……systematically developed evidence based statements which asisst providers, recipients and other stakeholders to make informed decisions about appropriate health interventions…………
Clinical guidelines: - Aims Appropriate care Best available evidence Multidisciplinary groups Systematic and transparent concensus processes End-user involvement Adaptations should be re-edited Guidance of doctors Do not replace knowledge and skills
AGREE-II (www.agreetrust.org) 23-point checklist: ….scope and purpose ….stakeholder involvement ….rigour of development ….clarity ….presentation ….applicability ….editorial independence
Guidelines - pros Facilitate EBM Variation in practice Discourage outdated practice Efficiency healthcare↑ Freeing resources? Awareness on subjects↑ Source of practical advice Standardize clinical management
Guidelines - con Designed for ”average” patients Implementation difficult: - lack of expertise - disagreement - resources Professional judgement Conflicts of interest Expensive Authority Duplication Lack of relevant research of high quality Legal consequences
Types of knowledge →Explicit knowledge →”tacit knowledge”
Requirements to guidelines Support not constraint Address practical questions Short and concise Standardized (e.g. AGREE-II) New→ Why? Add? Divergence? Evidense ↔ Expert opinion Conflicts of interest Reviewing Revision
Who develops the guidelines? Local departments/hospitals Cluster of hospitals National International/continental
Carlisle’s Conclusions ……………. if data with unusual distributions are removed from meta-analysis and articles by Fujii et al. excluded, then the antiemetic effects of granisetron and ramosetron are greatly reduced; further, there is no evidence of synergism between antiemetics and indeed, some evidence of antagonism between antiemetic agents…………...
Conclusions • Transfer of research possible but success varies • Gap between recommended and received healthcare • Causes of knowing-doing gaps unknown • Complex and context dependent process • Need for assessment of interventions • Best implementation strategy unknown • Economics?
