Mark van den Boogaard, RN, Ph.D., has a background as ICU nurse and is Professor of Nursing Science in Acute and Intensive Care at the department of intensive care of the Radboud university medical center in Nijmegen, the Netherlands where he is leading three research lines. One on ICU delirium with a special interest in prediction and prevention, leading several multicenter and multinational cohort studies and RCTs. The second line is focused on long-term outcomes of ICU-survivors where he is the project leader of the MONITOR-IC study (www.monitor-ic.nl/home-english). A multicenter cohort study including thousands of ICU survivors with a follow-up of 2-5 years collecting data of patient-reported outcomes, medical outcomes and costs obtained from health insurance companies. These data will be used to develop and implement treatment policies both in and outside of the ICU to prevent and mitigate PICS symptoms. MONITOR-IC represents the largest ICU long-term outcome project worldwide. The third line is on personalized ICU care. This line was recently set up and the firs steps are made in this field.
