This book trains the next generation of scientists representing different disciplines to leverage the data generated during routine patient care. It formulates a more complete lexicon of evidence-based recommendations and support shared, ethical decision making by doctors with their patients.
Diagnostic and therapeutic technologies continue to evolve rapidly, and both individual practitioners and clinical teams face increasingly complex ethical decisions. Unfortunately, the current state of medical knowledge does not provide the guidance to make the majority of clinical decisions on the basis of evidence.
The present research infrastructure is inefficient and frequently produces unreliable results that cannot be replicated. Even randomized controlled trials (RCTs), the traditional gold standards of the research reliability hierarchy, are not without limitations. They can be costly, labor intensive, and slow, and can return results that are seldom generalizableto every patient population. Furthermore, many pertinent but unresolved clinical and medical systems issues do not seem to have attracted the interest of the research enterprise, which has come to focus instead on cellular and molecular investigations and single-agent (e.g., a drug or device) effects. For clinicians, the end result is a bit of a “data desert” when it comes to making decisions. The new research infrastructure proposed in this book will help the medical profession to make ethically sound and well informed decisions for their patients.
MIT Critical Data
MIT Critical Data consists of data scientists and clinicians from around the globe brought together by a vision to engender a data-driven healthcare system supported by clinical informatics without walls. In this ecosystem, the creation of evidence and clinical decision support tools is initiated, updated, honed and enhanced by scaling the access to and meaningful use of clinical data.

Peter gained the degree of MEng in Engineering Science in 2010 from the University of Oxford. Since then he held a research position, working jointly with Guy's and St Thomas' NHS Foundation Trust, and King's College London. Peter’s research focuses on physiological monitoring of hospital patients, divided into three areas. The first area concerns the development of signal processing techniques to estimate clinical parameters from physiological signals. He has focused on unobtrusive estimation of respiratory rate for use in ambulatory settings, invasive estimation of cardiac output for use in critical care, and novel techniques for analysis of the pulse oximetry (photoplethysmogram) signal. Secondly, he is investigating the effectiveness of technologies for the acquisition of continuous and intermittent physiological measurements in ambulatory and intensive care settings. Thirdly, he is developing techniques to transform continuous monitoring data into measurements that are appropriate for real-time alerting of patient deteriorations.

In 2011, Mohammad received an MPhil in Information Engineering from the University of Cambridge where he was also a recipient of the Gates-Cambridge Scholarship. Since arriving at MIT, he has perused research at the interface of machine learning and medical informatics. Mohammad's doctoral focus is on signal processing and machine learning techniques in the context of multi-modal, multi-scale datasets. He has helped put together the largest collection of post-anoxic coma EEGs inthe world. In addition to his thesis work, Mohammad has worked with the Samsung corporation, and several entities across campus building “smart devices” including: a multi-sensor wearable that passively monitors the physiological, audio and video activity of a user to estimate a latent emotional state.
Alistair Johnson
Alistair joined the Laboratory for Computational Physiology as a postdoctoral associate in 2015. He received his B.Eng in Biomedical and Electrical Engineering at McMaster University, Canada, and subsequently read for a D.Phil in Healthcare Innovation at the University of Oxford. His thesis was titled “Mortality and acuity assessment in critical care”, and its focus included using machine learning techniques to predict mortality and develop new severity of illness scores for patients admitted to intensive care units. Before joining the LCP, Alistair spent a year as a research assistant at the John Radcliffe hospital in Oxford, where he worked on building early alerting models for patients post-ICU discharge. Alistair’s research interests revolve around the use of data collected during routine clinical practice to improve patient care.
Matthieu Komorowski
Matthieu holds board certification in anesthesiology and critical care in both France and the UK. A former medical research fellow at the European Space Agency, he completed a Master of Research in Biomedical Engineering at Imperial College London focusing on machine learning. Dr Komorowski now pursues a PhD at Imperial College and a research fellowship in intensive care at Charing Cross Hospital in London. In his research, he combines his expertise in machine learning and critical care to generate new clinical evidence and build the next generation of clinical tools such as decision support systems, with a particular interest in septic shock, the number one killer in intensive care and the single most expensive condition treated in hospitals.
