Ruud Nijman is an NIHR academic clinical lecturer at Imperial College in the platform Science and bioinformatics, with a special interest in diagnostics and clinical decision making in paediatric emergency medicine and infectious diseases. He is also a RCPCH GRID specialty registrar in Paediatric Emergency Medicine in the London deanery.
He originally trained as a medical doctor at the Erasmus University in Rotterdam, The Netherlands (2007). He completed his PhD in Paediatrics at the Erasmus University in Rotterdam, The Netherlands, on the topic of diagnostic strategies for children with fever at risk of serious bacterial infection presenting to emergency care under the supervision of Prof. Henriette Moll and Prof. Ewout Steyerberg (2014; available at: http://hdl.handle.net/1765/77189). He also completed an MSc in Clinical Epidemiology at the Netherlands Institute of Health Sciences (2011). He made the transition to Imperial College to continue his academic work under the supervision of Prof. Ian Maconochie in 2013.
His academic work until now has focussed mainly on the recognition and management of children at risk for serious bacterial infections presenting to the emergency department. This work included the development and validation of clinical prediction models, assessing the clinical utility of vital signs and biomarkers, and evaluating management strategies of children at risk for sepsis. Ruud was one of the main authors of the first Dutch national guideline on the management of children with fever in secondary care (available at:http://www.nvk.nl/tabid/1558/articleType/ArticleView/articleId/887/default.aspx)
He is currently an active researcher within the PERFORM consortium (chief investigator: Prof. Levin, Imperial College): a multi-centre, Horizon 2020 funded, study recruiting children with acute infections with the aim to discover and validate new biomarkers to differentiate viral and bacterial infections (https://www.perform2020.org). He is involved in ongoing studies looking at the epidemiology of children of fever visiting the emergency department, led by the team at the Erasmus MC, Rotterdam, the Netherlands (Principle investigator: Prof. Henriette Moll). He also applies metabolomic platforms in an attempt to identify metabolites associated with bacterial infection, with the goal of building point of care diagnostics tests, in a collaboration with Dr. Xinzhu Wang and Prof. Myra McClure (Imperial College). As a visiting fellow, he is part of the team within the PERFORM consortium evaluating the health economics of implementing a potential new diagnostic test in children with fever in health care systems across Europe, together with researchers at the London School of Hygiene and Tropical Medicine (Principal investigator: Dr. Shunmay Yeung).
In addition, he was principal investigator of a study looking at the management of refugee children presenting to emergency departments across Europe. This project was performed in collaboration with the Research in European Paediatric Emergency Medicine (REPEM) Network (http://repem.net) and the Paediatric Emergency Research in the UK and Ireland (PERUKI) network (https://www.peruki.org), and received financial support from the European Society of Paediatric Infectious Diseases.
Ruud coordinates the regional training days for trainees in Paediatric Emergency Medicine. He is also one of the course directors for the Imperial College preparation course for the clinical membership of the RCPCH, which is being held three times a year: https://www.imperial.ac.uk/medicine/study/short-courses/mrcpch-part-2/.
Ruud was one of the author’s of two children’s books to promote patient education of children presenting to the emergency department:
