Mike trained as a General Paediatrician in the UK but has worked in Kenya (where he is still based) for over 20 years supported by a series of Wellcome Trust research fellowships. In 2004 he started the Child and Newborn Health Group in collaboration with Kenya’s Ministry of Health and the University of Nairobi. This transitioned in 2011 to the broader Health Services Unit also based in Nairobi which Mike heads. Mike’s team has developed national, evidence-based guidelines for care of children and newborns and the linked ETAT+ skills training course, both now used in a number of countries. The team uses a range of methodologies spanning statistical modeling to ethnography in research aimed at improving hospital care for children and newborns. A major current project involves a 14 hospital clinical network using detailed information on all paediatric admissions and more recently neonatal admissions as part of a formative learning system strategy. Mike also leads the Oxford Health Systems Research Collaboration (OHSCAR). Together with Kenyan partners this team is examining system strategies to improve care quality and safety more generally. The Kenyan HSU team regularly contributes to working groups of the Kenyan government, WHO and other organisations.
