Having More Than One Chronic Disease Amplifies Expenditure of Diseases: Study

A country has to bear more costs when citizens suffer from two or more non-communicable diseases (multi-morbidity) than the sum of individual diseases would cost, reveals recent study by the University of Otago, New Zealand. These findings of the study published in the journal PLOS Medicine.

Few studies have estimated disease-specific health system expenditure for many diseases simultaneously. In the new work, the researchers used nationally linked health data for all New Zealanders, including hospitalization, outpatient, pharmaceutical, laboratory and primary care from July 1, 2007 through June 30, 2014. These data include 18.9 million person-years and $26.4 billion US in spending. The team calculated annual health expenditure per person and analyzed the association of this spending to whether a person had any of six non-communicable disease classes--cancer, cardiovascular disease, diabetes, musculoskeletal, neurological, and lung/liver/kidney (LLK) diseases--or a combination of any of those diseases.

59% of publically-funded health expenditures in New Zealand were attributable to non-communicable diseases. Nearly a quarter (23.8%) of this spending was attributable to the costs of having two or more diseases above and beyond what the diseases cost separately. Of the remaining spending, heart disease and stroke accounted for 18.7%, followed by musculoskeletal (16.2%), neurological (14.4%), cancer (14.1%), LLK disease (7.4%) and diabetes (5.5%). Expenditure was generally the highest in the year of diagnosis and the year of death.

"There is a surprising lack of disease-attributed costing studies involving multiple diseases at once," the authors say. "Governments and health systems managers and funders can improve planning and prioritization knowing where the money goes."
