ISAM Global Experts Network (ISAM GEN): Expert Elicitation with Addiction Medicine Professionals




ISAM-GEN recent activities and events

We are happy to share the proceedings of the first ISAM GA of AM Societies which ran with over 150 attendees and 50 speakers from 40 countries on February 10, 2022








ISAM-GEN held a workshop and webinar on November 11th, 2021, featuring 20 speakers coming from a wide range of disciplines, aiming to take the first steps toward conducting a global expert survey and developing the World Addiction Medicine Report.

Bringing together experts in addiction medicine and expert elicitation, this workshop featured talks on cutting-edge expert elicitation methods and ISAM’s Global Expert Network (ISAM-GEN) initiative. We hope this webinar will be the first step in shaping a working group to design a longitudinal global expert survey and develop the World Addiction Medicine Report. Attendees from across addiction science disciplines are welcome to attend the webinar to learn how they may join the working group and have a voice in this evolving project. The following short survey was provided throughout the meeting to ask about attendees’ interests and how they can join the global expert network (survey link:

Background and mission statement

Expert opinion constitutes an important source of information, especially when other types of data are scarce, the issues under discussion are complex and difficult to address with available data, or there is a need for rapid synthesis of information and intervention formulation. The dynamic and complex nature of substance use disorders and behavioral addictions necessitates the formation of global networks which can rapidly identify emerging challenges, synthesize cross-national information, and provide valid consensus opinions on areas of disagreement. To assess shifts in the patterns of addiction and national service provision to affected individuals, an ISAM working group conducted a survey of 189 experts in addiction sciences from 72 countries in 2020.

The ISAM Global Expert Network (ISAM-GEN) aims to build on this endeavor and develop a global expert infrastructure based around ISAM which can enable valid and reliable expert elicitation and consensus-building in the various sub-disciplines of addiction sciences.

Past and Current projects

In response to unprecedented challenged posed by the COVID-19 pandemic, the International Society of Addiction Medicine (ISAM) in March 2020 delineated practical guidelines for addiction researchers and policymakers to support decision making during the pandemic ( Almost one month after this announcement, in April 2020, ISAM conducted a rapid, multi-phasic expert survey of informants from across the globe to investigate the impacts of the COVID-19 on different aspects of addiction medicine during the pandemic; including changes in the patterns of drug and alcohol use, price alterations, virtual care, education and training qualities, and addiction treatment and harm reduction services for high-risk populations with substance use disorders. The study protocol was published in June 2020 ( A total of 185 respondents from 77 countries participated in the first phase of this global survey:

Given the lack of multicentric addiction epidemiology studies in the early months of the COVID-19 pandemic, the ISAM global survey investigated the status of substance use during a 5-week period starting in April 4th, 2020. Respondents from 77 countries reported a significant decrease in drug supply (69.0%), and an increase in prices of the alcohol and drugs market (95.3%) in their countries. The findings also suggested an increase in the usage of alcohol (71.7%), cannabis (63.0%), prescription opioids (70.9%), and sedative/hypnotics (84.6%), while the use of amphetamines (59.7%), cocaine (67.5%), and opiates (58.2%) was reported to be decreasing. A majority of experts also reported increases in complications related to drug and alcohol use ( An overall rating of the general impact of the pandemic on people with substance use disorders is presented below:

Lastly, the results of this global expert survey suggested an alarming impact on substance use treatment and harm reduction services during the first few months of the COVID-19 pandemic, with more than 40% of represented countries having experienced partial discontinuations of important harm-reduction services. Based on this survey, the directors of the ISAM global survey highlighted several issues which needed to be tackled more effectively (

Current projects

The ISAM-GEN is currently working to further develop and validate the global expert survey infrastructure required for future global surveys. A webinar summarizing the experience of the prior ISAM global survey, important challenges in developing valid expert surveys, and future directions will be held in the autumn of 2021
