Multimorbidity is defined as the co-occurrence of two or more chronic medical conditions in one person.


The progress of modern medicine has substantially increased life expectancy and improved the outcome of previously fatal diseases. As a consequence, chronic medical conditions and multimorbidity are increasing. Multimorbidity correlates with age and might represent the most common "disease pattern" found among the elderly. Today, multimorbidity is turning into a major medical issue for both, individuals and health care providers.

Multimorbidity is characterised by complex interactions of co-existing diseases where a medical approach focused on a single disease does not suffice. However, there is only little scientific knowledge available for appropriate diagnostic reasoning, care and treatment for multimorbid patients. The current fragmented health care system does not meet the complex needs of multimorbid patients. Integrated health care models with well-balanced treatment plans tailored toward the needs of the individual person are required.

What is Multimorbidity.NET?

Multimorbidity.NET is an open, interdisciplinary scientific network of researchers and experts from the public health system aiming to develop and establish an inter- and transdisciplinary centre of excellence in the field of multimorbidity. To date, the network comprises research units from the Medical and Philosophical Faculty of the University of Zurich and of other institutions.

The aim of our work is a broad understanding of multimorbidity from different perspectives.
We plan to develop a new conceptional framework with new approaches to understand multimorbidity and its management. The main purpose is the development of evidence-based programs and the acceleration of translational science into clinical practice.

We assume that multimorbidity is more than the sum of the single diseases results in complex disease patterns requires practices and approaches (in diagnostics and therapy) which differ substantially from traditional approaches focused on a single disease plays a significant role in aging.
