Patricia Stassen

Associate professor

I completed my medical school in Maastricht in 1995. Then I was trained in internal medicine and specialized in nephrology in UMCG, where I also completed my PhD thesis on Wegener’s disease. Since 2008, I have worked at MUMC+, where I also started/designed a new internal medicine specialization: acute medicine. Since 2010, I have worked as chief of acute internal medicine in addition to practicing as an all-round clinician and engaging in student, nurse and resident education within the faculty of medicine and health. I was appointed as an associate professor (mixed profile) in 2022.

My area of interest is acute internal medicine. I concentrate on all kinds of diseases ranging from sepsis to cardiovascular diseases, and include not only the emergency department (ED) but also the trajectory before (general practitioner, EMS, acute internal medicine, emergency medicine) and after the ED (MCU/ICU).

The aim of my research is to improve acute care and to achieve a short laboratory-to-bed-time. In addition, my aim is to involve students and to improve their skills in both science and acute medicine. Currently, I am working on the prediction of poor outcomes in ED patients using ML technology, on an exploration of the acute care trajectory and on the added value of simulation techniques for residents in the acute care.

I am member of the national research consortium in acute medicine that organizes short but original studies called “flash mobs” across the country. I also coordinate studies in Limburg in collaboration with acute internists and emergency physicians. My goal is to work with all kinds of professionals interested in acute medicine at MUMC/FHML, including intensivists, general practitioners, education/simulation experts, clinical chemistry specialists and cardiologists.

Until now, I have been a co-promotor of 7 PhD students, and I currently supervise 4 PhD students.
