Dr. Kathryn (Kathy) Rowan

Kathy RowanIn 1994, as a result of her DPhil (PhD) from the University of Oxford, Kathy established the Intensive Care National Audit & Research Centre (ICNARC) as an independent charitable (not-for-profit) organisation in the UK. ICNARC aims to promote improvements in the organisation and practice of critical care (both intensive and high dependency care) with a view to improving care and the outcomes and experiences of care for patients and for those who care for them ( ICNARC collaborates closely with many other local, regional, national and international organisations to help achieve this aim.

With respect to quality in critical care, ICNARC aims to contribute in three main areas: establishing quality; assessing quality; and improving quality. In establishing quality – the ICNARC Clinical Trials Unit, fully registered with the UK Clinical Research Collaboration, conducts a large and broad portfolio of research applying both quantitative and qualitative methods. In collaboration, ICNARC has won over £10 million in grants from a wide range of research funders. In assessing and improving quality, ICNARC has established and continues to develop two, major, national clinical audits both registered by the NHS Quality Accounts, one addressing adult critical care and one addressing in-hospital cardiac arrest. ICNARC promotes improvements in quality through routine comparative reporting at local, regional and national levels. In 2011, ICNARC released its first Annual Quality Report (2010-11 data) providing publicly identifiable results online (

From 1994 to 2013, Kathy led and directed ICNARC and, in 2004, was awarded the Humphry Davy Medal by the UK Royal College of Anaesthetists as a mark of distinction for her significant contribution to critical care. In 2004/05, Kathy completed a Harkness Fellowship in Health Care Policy in the USA. Following appointment of a Chief Executive in 2014, Kathy now acts as ICNARC’s Director of Scientific & Strategic Development and remains Director of its Clinical Trials Unit. Kathy is also an Honorary Professor in the Department of Health Services Research and Policy at the London School of Hygiene & Tropical Medicine and in the Division of Research Strategy at University College London.

Dr. Mervyn Singer – ISF Treasurer and Chair Elect

SingerProfessor of Intensive Care Medicine at University College London, UK. His particular research focus is on (i) mechanisms of multi-organ failure, especially the roles of mitochondrial dysfunction and myocardial depression; (ii) mechanisms and management of septic shock; (iii) management of infection and infection control and (iv) monitoring of organ perfusion and perfusion adequacy. There is a strong translational emphasis to his studies that aim to travel from bench to bedside and back again. He has a healthily iconoclastic approach to current dogma; regardless of whether or not he will be proved right, it is nonetheless important to challenge the veracity of ingrained views and practices.

He has been heavily involved in multiple academic- and industry-instigated multi-centre trials, e.g. CORTICUS and PAC-Man. He sits on the Wellcome Trust Technology Transfer Panel and was appointed a UK NIHR (National Institute of Healthcare Research) Senior Investigator in 2009. His major sources of research funding comes from the UK Medical Research Council, the Wellcome Trust, NIHR and European Commission. He has co-written/edited several textbooks including the Oxford Handbook of Critical Care and the Oxford Textbook of Critical Care.
