Celebrating 25 Years of GRADE

We believe better evidence leads to better health.

For 25 years, GRADE has been of transforming evidence into action – it’s the perfect time to reflect on that contribution and share work from the Melbourne GRADE Centre.

GRADE provides transparent, accessible methods and tools for assessing the certainty of evidence and making health decisions, including recommendations. GRADE centres and networks serves as the primary hub within the region for GRADE related questions and for support and collaboration opportunities.

For 25 years, the Melbourne GRADE Centre aims to help researchers, clinicians and policy makers understand, apply and trust GRADE — shaping guidelines, strengthening policy and building capacity across our country and the region..


Our story began with a single workshop back in 2017. Since then we’ve:

  • Led 70+ workshops for more than 1,600 participants

  • Delivered 26 customised workshops for 15 guideline groups

  • Supported the development of 5 NHMRC-approved guidelines (with more underway)

  • Contributed to many more guidelines nationally and internationally

  • Collaborated nationally and internationally on methods development and guidance to help others deliver trustworthy evidence and recommendations

  • Applied GRADE methods in evidence syntheses that have supported national guidelines and health policy decisions


Today, as one of only two GRADE Centres in Australia, we lead a regional program of advocacy, training and support, and contribute to the global evolution of GRADE methods.

Now, as we mark this 25 year global milestone for GRADE, we look back on the journey so far — and ahead to the next chapter of advancing evidence-informed decisions around Australia and across our region.

National Training: Building GRADE skills across Australia

From our first national workshop in 2017 to today, the Melbourne GRADE Centre has helped researchers, clinicians and policy makers across the country build the skills needed to apply GRADE with confidence. Our courses range from introductory sessions to Australia’s first two-day Evidence-to-Decision course, giving guideline panels and technical teams a practical, hands-on experience of turning evidence into recommendations.

Highlights:

  • 71 workshops delivered for 1,600+ participants

  • 30 full-day workshops, including our first NHMRC-supported event in 2017

  • 26 customised workshops for 15 guideline groups

Guidelines: From evidence to practice

Our GRADE work began in evidence synthesis, but quickly expanded to health decision making when the NHMRC endorsed the use of GRADE in clinical practice guidelines soon after we established the Melbourne GRADE centre. We have been fortunate to collaborate with guideline developers who share GRADE’s commitment to transparent evidence assessment, that empowers individuals, organizations, and policymakers to make informed, values-based decisions.

Our methods contributions span national and international guidelines across diverse areas — from dementia care and mental health to neonatal hypoglycaemia and immunisation - but all use the GRADE Evidence to Decision framework to make recommendations.

NHMRC: Supporting and Informing National Guidelines

From its inception, the Melbourne GRADE Centre has worked closely with the NHMRC to support the use of GRADE through provision of training, methods guidance and advice, and methodological review of guidelines and NHMRC-commissioned systematic reviews.

Our work aims to ensure guideline developers have access to guidance and support needed to meet the requirements for developing their guideline to NHMRC standards.

An example is our collaboration with the NHMRC to write the Guidelines for Guidelines module on Evidence to Decision and Making Recommendations. The module reflects our experience implementing GRADE with guideline developers, and is taught in our Evidence to Decision workshop. To find out more about our upcoming workshops visit our Training page.

Our commissioned reviews for the NHMRC show how GRADE can be used to interpret evidence. From the outset, we design reviews with the GRADE summary of findings in mind – asking ‘what is the most effective way to bring together this evidence to inform decisions and meet the needs of the commissioner’.

The complexity of these reviews – such as in the suite of natural therapies reviews - has provided opportunity to road test new methods we have developed, like the InSynQ tool for planning synthesis questions.

These reviews can reveal critical areas for methods research, including that led by Professor Joanne McKenzie on analysis and meta-analysis of interrupted time series which she says “arose from collaboration on reviews to inform NHMRC’s guidelines on infection control”.

International Training: Sharing expertise worldwide

As part of the global GRADE community, we contribute to training and knowledge exchange beyond Australia. Our team has been invited to deliver workshops internationally, most recently in Shanghai in 2025, where we taught methods for integrating evidence from both randomised and non-randomised studies.

This full day workshop was developed and delivered in collaboration with colleagues from the McMaster GRADE Centre in Canada and the Freiburg GRADE Center in Germany, with generous contributions from Carlos Cuello Garcia, Holger Shuenemann, and other members of the GRADE working group who developed the guidance on which the workshop was based. 

Highlights:

  • Invited to lead international training programs

  • Active contributions to the GRADE Working Group

  • Collaborations with colleagues worldwide to refine and share best practice

  • “GRADE centers and networks exist to champion the GRADE approach - empowering the global community through expert training, widespread promotion, and practical implementation. Their mission? To support the GRADE working group in transforming evidence into action.”

  • “Practice guidelines can play a pivotal role in advancing health equity; yet, few organisations use tools to systematically integrate health equity considerations.”

  • Did you know that “reviewers should search for and evaluate NRSI, if they consider it plausible that NRSI will yield evidence equal or superior to that from the RCTs.”

    Cuello Garcia et al 2022

    Here’s the GRADE guidance

  • “Sometimes, a guideline panel might judge the certainty that the desirable effects of an intervention clearly outweigh its undesirable effects as high, but the body of supportive evidence is indirect.”

    Dewidar et al 2022
