A methodology for consensus-building
Despite impressive scientific and medical advances, the world’s response to the COVID-19 pandemic has been hampered by political, socio-economic and behavioural factors, including a lack of global coordination, inequitable access to vaccines and treatments, and disinformation. “Each country has responded differently, and often inadequately, mostly because of a serious lack of coordination and of clear goals,” says Lazarus.
To develop a global consensus on how to address these issues going forward, he and his colleagues conducted a Delphi study—a well-established research methodology that challenges experts to reach a consensus on answers to complex research questions. More than 386 academic, health, NGO, government and other experts from 112 countries took part in three rounds of consultation.
