POD Webinar Series Episode 2

19 Oct 2020 – 16:00 EST

Steven Woloshin and Barry Kramer will be joined by Don Berry and Jennifer Moss who will tackle some of the issues surrounding overscreening of cancer in the elderly and statistical modelling in healthcare.

Dr. Jennifer Moss is an expert in geographic disparities in cancer prevention behaviors, including vaccination, tobacco use and screening.

Overscreening for cancer can cause harms to patients as well as increased healthcare costs and inefficiencies. We used national survey data to determine the prevalence of overscreening for cancer among older adults. Overall, about half or more of older adults report receiving a cancer screening after the recommended upper age limit. People were more likely to be overscreened if they lived in metropolitan areas, had a usual source of healthcare, reported good health, had higher educational attainment, or were married. Overscreening did not decrease meaningfully by age or life expectancy. Interventions are needed to reduce overscreening and associated harms.

Don Berry is Professor of Biostatistics at the University of Texas M.D. Anderson Cancer Center. He got a PhD in Statistics from Yale University a long time ago. For the last 20 years he’s led a modeling group in breast cancer as part of an NCI-funded U01 in the CISNET program (Cancer Intervention and Surveillance Modeling Network). During this same period he’s served as a member of NCI’s PDQ Screening and Prevention Editorial Board.

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.

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.

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.”
