People with multimorbidity (two or more coexisting conditions in an individual) are more likely to die prematurely, be admitted to hospital and have an increased length of stay than people with a single chronic condition.
Multimorbidity is also associated with poorer function and health-related quality of life (HRQOL), depression and intake of multiple drugs (polypharmacy) and greater socioeconomic costs. Most health care is designed to treat individual conditions rather than providing comprehensive, person-centreed care, which often leads to fragmented and sometimes contradictory care for people with multimorbidity and increases their treatment burden. Moreover, treating one condition at a time is inefficient and unsatisfactory for both people with multimorbidity and their health-care providers.
