Healthcare costs in chronically ill community-living older adults are dependent on mental disorders

Abstract

Background

The economic impact on society associated with the healthcare of older adults depends on their health status. The aim was to estimate the excess costs associated with co-morbid mental and physical disorders.

Methods

Data were from a health survey of 2004 older adults. Two-year healthcare costs were identified from administrative databases. Generalized linear models were used to study healthcare costs as a function of co-morbid mental disorders (MDs) and heart disease (HD), arthritis, diabetes, cancer, respiratory disease (RD) and cerebral vascular accident (CVA).

Results

Participants with HD and CVA with MD incurred higher costs reaching $1696 (95% confidence interval (CI): $30, $3422) and $14 772 (95% CI: $1909, $31 454) than those without MD. RD and MD incurred higher costs reaching $5343 (95% CI: $343, $10 343) than those without RD. The excess annual adjusted healthcare costs associated with co-morbid MD and physical disorders reach close to $600 M per 1 000 000 population of older adults.

Conclusion

The presence of MDs with HD, CVA and RDs has a synergistic effect on healthcare costs. These findings underline the need for improved primary care for the prevention and treatment of co-mental and physical disorders that can potentially save hundreds of millions to society.
