Holger Schünemann Professor and Chair, Dept. of Clinical Epidemiology & Biostatistics Professor of Medicine Michael Gent Chair in Healthcare Research McMaster University, Hamilton, Canada New York, December 10, 2012How to develop pragmatic and trustworthy guidelines
Disclosure • Co-chair GRADE Working Group • World Health Organization: Advisory Committee for Health Research, Expert Advisory Panel on Clinical Practice Guidelines and Clinical Research Methods and Ethics & Chair of various guideline panels; funding for guideline development/SR • Work with various other guideline groups using GRADE • American College of Physicians (ACP) Clinical Practice Guidelines Committee • American College of Chest Physicians (ACCP) • No direct/personal payments from drug or device industry
“Pragmatic” (rapid?) systematic reviews • How to? • Challenges • Solutions • Integration in guidelines • Developing recommendations (example and small group work) ontent C
Institute of Medicine Report on Trustworthy guidelines • Be based on a systematic review of the existing evidence; • Be developed by a knowledgeable, multidisciplinary panel of experts and representatives from key affected groups; • Consider important patient subgroups and patient preferences as appropriate; • Be based on an explicit and transparent process that minimizes distortions, biases, and conflicts of interest; • Provide a clear explanation of the logical relationships between alternative care options and health outcomes, and provide ratings of both the quality of evidence and the strength of recommendations; and • Be reconsidered and revised as appropriate when important new evidence warrants modifications of recommendations.
Working with evidence at WHO • For key recommendations: • Search for and retrieve all available evidence • Identify relevant SRs • Formally assess quality of evidence • GRADE (systematic and transparent approach) • Ideally based on systematic reviews
Rapid & pragmatic but systematic • Why? • Resources or Time (or both) • Transparency is key • Methods do not have to differ if more capacity in the team
Team with expertise • Manage bias/COI (team and others) • Stakeholder input • Formulate topic • Develop protocol • PICO • Protocol for peer review & make public • Comprehensive search • Address biased reporting • Screen and select • Manage data selection • Critically appraise studies • Evaluate body of evidence (GRADE) • Qualitative and quantitative summary • Structured report • Peer review • Public access R apid & pragmatic IOM

Allergic Rhinitis in Asthma (ARIA) Guidelines • Model applied to many other guidelines (e.g. for WHO, WAO, ACCP)

Panel • Grade recommendations • For or against (direction) • Strong or conditional/weak (strength) • By considering balance of: • Quality of evidence • Balance benefits/harms • Values and preferences • Revise if necessary by considering: • Resource use (cost) Systematic review Guideline • Formulate Recommendations ( | …) • “We recommend using…” | “Clinicians should…” • “We suggest using…” | “Clinicians might…” • “We suggest not using…”| “Clinicians … not…” • “We recommend not using…”| “Clinicians should not…”
Steps • e.g. missing outcomes • Use same search strategy • Do meta-analysis or assess similarity of results
48 recommendations + recommendations for subgroups 84 evidence profiles
R apid guidelines
Budget • Usually $5,000 to 10,000 per evidence profile • ARIA ~ $300,000 plus meeting cost
Summary • Pragmatism can retain transparency • Following SR methods, including evidence profiles enhances transparency • Progress on moving from evidence to recommendations
