For over three decades, Frank Shann's pocket reference has been a constant companion for physicians worldwide — in hospitals, ICUs, and clinics from Melbourne to Malawi.
Professor Frank Shann is an Australian pediatric intensivist and former Director of Intensive Care at the Royal Children’s Hospital in Melbourne. In 1995, he became Australia’s first Professor of Critical Care Medicine at the University of Melbourne. His pioneering research has helped shape pediatric intensive care internationally, particularly through the development of the Pediatric Index of Mortality (PIM) and studies on the organization and outcomes of intensive care services. In 1983, he first published Drug Doses, based on a practical dosing reference he had developed for his own clinical practice. Over the following decades, the booklet became a widely used resource for physicians and nurses worldwide, reaching its 17th edition in 2017. His contributions to medicine and child health, including his work in developing countries, were recognized with his appointment as a Member of the Order of Australia.
Today, his research focuses mainly on vaccines for children in low- and middle-income countries, where most deaths in young children occur, while he completes several studies in pediatric intensive care. In 2025, The BMJ published a large randomized trial he conducted with colleagues in three neonatal intensive care units in south-east India. It showed that giving the BCG and oral polio vaccines to newborn babies weighing less than 2,000 g in their first days of life reduced deaths in the first month of life.
Professor Oliver Karam is a pediatric intensivist and Professor of Pediatrics at Yale School of Medicine, where he also directs the Master of Health Science in Clinical Investigation program. Originally from Switzerland, he received his medical degree from the University of Geneva, completed his pediatric critical care training in Montreal, Canada, and earned a PhD in Clinical Research from the University of Lille, France. He has practiced pediatric intensive care in Switzerland and the United States, holding several clinical and academic leadership positions. His research focuses on improving outcomes in critically ill children, particularly those requiring extracorporeal membrane oxygenation (ECMO), with an emphasis on transfusion strategies, bleeding, and thrombosis. He has authored more than 200 scientific publications and contributes to several international research networks and clinical guidelines.
His involvement with DrugDoses began in 2001, while he was still a medical student in Geneva. Around the same time that he purchased a copy of Frank Shann’s Drug Doses booklet, he also acquired a Palm OS handheld device. The idea of having such a valuable clinical reference available electronically prompted him to contact Frank Shann, and together they launched the first electronic version of DrugDoses in 2002. Initially developed for Palm OS, the application subsequently expanded to Windows CE, followed by iOS in 2009 and Android in 2010. More than two decades later, what Oliver values most about DrugDoses is the opportunity to connect with users from around the world. Their feedback, suggestions, and shared experiences have transformed what began as a small technological project into a community of clinicians united by a common passion for pediatric intensive care.
