POD Webinar Series Episode 3

17 Nov 2020 – 16:00 AEDT

Learning from the pandemic: Can COVID-19 help us build a better healthcare system?


The Asia-Pacific, and final, PODC webinar for 2020 is hosted by PODC partner Wiser Healthcare. This webinar will focus on system impacts of COVID-19 and potential future implications for the healthcare system, addressing these questions:


1.    How has healthcare service utilisation changed during the COVID-19 pandemic, and what has this revealed about effective and ineffective care?

2.    Have these changes made things better or worse for patients, publics, healthcare workers, and healthcare systems?

3.    Can COVID-19 disruption help healthcare build back better: with less low value care, more needed care, and minimal under- and overdiagnosis?


The event will be chaired by senior Wiser Healthcare investigator Prof Paul Glasziou, who will welcome two speakers followed by a moderated Q&A panel discussion. We are excited to announce the following participants:



–          Prof Anne Duggan, ACSQHC 

–          A/Prof Ray Moynihan, Wiser Healthcare



–          Kim Sutherland, ACI NSW

–          Dr Megan Keaney, DoH 

–          Leah Hardiman, Health Consumer

–          Prof Jenny Doust, Wiser Healthcare/GP

–          A/Prof Katy Bell, Wiser Healthcare




Registration is available HERE



CANCELLED – Preventing Overdiagnosis 2020

Given circumstances dictated by the current pandemic, we are regrettably no longer able to host Preventing Overdiagnosis 2020 in Oxford and have made the very difficult decision to cancel the face to face event.

The good news is there will be something and no travel is required. The scientific committee are working on producing a virtual event in the same week (Sept 14-16).  More details on that and plans for 2021 to follow.


What should you do now?


You can request a full refund or transfer your registration to PODC2021.  If you prefer a refund please email Ruth with your booking reference number and we’ll take care of it as a matter of urgency.  If you are transferring your registration there is no action required.


Abstract Submissions

The abstract portal will stay open for submission to PODC2021.  Any updates can be made directly in the portal using your login details.  If you experience any problems making changes please email Ruth.


Thank you for your patience, keep well.

With best wishes
Conference Scientific Committee



A statement from several major health organisations



Copenhagen Statement


The international Preventing Overdiagnosis conference was held in Copenhagen in August 2018 with delegates from over 30 countries.

The following statement was adopted by the participants at the end of the conference:

This conference regrets the fact that the draft Astana Declaration on Primary Health Care 2018 (From Alma-Ata towards Universal Health Coverage and the Sustainable Development Goals) makes no reference to the public health and clinical  challenges of overdiagnosis and overtreatment.  These challenges include direct harms to patients and citizens, misallocation of resources, and, over the longer term, they threaten the sustainability of universal healthcare systems and so undermine global health.  Sustainable health systems must explicitly manage the twin problems of underuse and overuse.

“Squidgy” Guidelines: What are they and what can we do about them? (http://www.cebm.net/squidgy-guidelines-can/)

Ever try to catch a jellyfish? Or squeeze a squid in your hand? Or wrestle with an octopus?  You can’t deny that these squishy, and malleable invertebrates share one important characteristic:  They have no spine.

#PODC2016 has raised the bar for research

“The Preventing Overdiagnosis Conference held in Barcelona last month gathered over 400 participants from across the world. Many voices were heard since plurality was represented in the presence of patient representatives, health care professionals, researchers, and journalists among others.”
