Multimorbidity is the term used to describe patients that have two or more chronic diseases at any one time. Australian studies have indicated that approximately 30% of all GP attendances are for patients with multimorbidity.

The likelihood of having two or more chronic diseases increases with age with more than 80% of patients aged 75 years or older having multimorbidity. A systematic review indicated the most common pair of conditions across studies was osteoarthritis and a cardio-metabolic condition, such as hypertension, diabetes, obesity, or ischaemic heart disease. The BDHP Chronic Disease Theme will facilitate opportunities for clinicians and researchers to participate in research translation activities to increase the integration of evidence based care for patients with multimorbidity.
