Physicians’ Professional Performance: Between Time and Technology is an inspiring plea for ‘doctors with cool heads and warm hearts’ by Kiki Lombarts. Lombarts is Professor of Professional Performance at the University of Amsterdam, the Netherlands. Marcel Levi, MD, Chief Executive University College London Hospitals and Professor of Medicine, University College London, UK:It is amazing how Kiki Lombarts has been able to distil the professional performance of doctors into three concise but defining concepts. Indeed, as a practising doctor, striving for excellence in patient care, acting with compassion and according to humanistic values, and being accountable for my interaction with patients and healthcare colleagues, very adequately summarizes my personal professional objectives. Yvonne Steinert, clinical psychologist, Director of the Centre for Medical Education and Professor of Family Medicine at McGill University, Montreal, Canada:Kiki Lombarts’ description of the three pillars of physicians’ professional performance underscores the importance of professionalism and professional identity formation in the practice of medicine. Based on 25 years of research and a thorough understanding of the relevant literature, this work, which clearly ties professional performance to patient care, offers invaluable insights for students and practitioners alike. Cees van der Vleuten, psychologist, Scientific Director of the School of Health Professions Education and Professor of Education, University of Maastricht, the Netherlands:Self-regulation is a key assignment for the medical profession. This is not an easy task. Kiki Lombarts highlights the challenges and will inspire you to fulfil your professional responsibilities with knowledge, fun and compassion.
