Marjan van den Akker, PhD

Marjan van den Akker

Marjan was trained as a health scientist and epidemiologist and is working as an associate professor at the departments of Family Medicine of Maastricht University (the Netherlands) and the Academic Center for General Practice of the KU Leuven (Belgium).

Her research activities focus on comorbidity, multimorbidity, polypharmacy, psychosocial profiles in longitudinal perspective and well-being of older cancer patients/survivors as well as the role of family medicine in the care for cancer survivors.

As a young researcher, her main focus of research was epidemiological studies on multimorbidity (prevalence and incidence of multimorbidity and associations with psychosocial characteristics, as well as descriptive studies of co-morbidity of chronic diseases). Increasingly, this incorporates more complex longitudinal epidemiological analyses of the development of multimorbidity and polypharmacy, disentangling morbidity and medication patterns. Furthermore, analyses focus on interactions (disease-disease, treatment-treatment, and treatment-disease), the feasibility of applying (disease specific) guidelines to patients who have multimorbidity, and incorporating patient preferences.

Current studies regarding multimorbidity and polypharmacy include epidemiological analyses of data from the Registration Network Family Practices (RNH) of the Department of Family Medicine Maastricht University, data from the Maastricht Aging Study (MAAS) of the Department of Psychiatry and Neuropsychology (Maastricht University) and data from the Intego database of the Academic Center for General Practice (KU Leuven); and an RCT evaluating a multidisciplinary intervention to optimise medication profiles in people using multiple chronic medication. New studies in this area are being planned.
