Member Profile

Dr. Alfonso Iorio

I started as a clinical trialist (1995-2010), and quickly moved on to be a meta-analyst (1997 to date). I joined the Cochrane Collaboration (Individual Patient Meta-analysis Method Group 1999; Prognosis Method Group 2003; and Cystic Fibrosis and Genetic Disorders group, for which I am associate editor since 2005). I led the Italian Society for Thrombosis and Hemostasis Guideline Program from 2004 to 2010, and the NHF guideline program in 2014-15. I set up-up and ran the National Italian Hemophilia and Bleeding Disorders Registry and redesigned the Canadian Bleeding Disorder Registry. I lead two international groups performing IPD meta-analyses on the predictive value of D-dimer (ISTH) and determinants of inhibitor development in hemophilia (EAHAD). In 2010, I joined the Health Information Research Unit, McMaster University, and the GRADE working group, where I lead the working group on Prognosis. Since 2014, I am the Chairman of the Data and Demographics Committee of the World Federation of Hemophilia. Since July 2015, I am the Director of the Health Information Research Unit. In 2015, I was called to serve on the Guideline Oversight Committee of the American Society of Hematology.
