• People with multimorbidity consume a disproportionately large share of healthcare resources
• Greater resource consumption is the result of not only greater need because of the accumulation of chronic diseases but also interactions and synergies between conditions present within individuals
• Multimorbidity measures have been shown to explain large variations (across populations/individual clinicians/healthcare organizations) in use of a range of healthcare resources – including inpatient services, specialized care, primary care and medications
• Multimorbidity has important implications for resource allocation within health systems as well as for care management programmes targeted at improving care and increasing care efficiency for high-risk multimorbid patients.
