Cost Effective Community Based Dementia Screening : A Markov Model Simulation

الملخص EN

Background.

Given the dementia epidemic and the increasing cost of healthcare, there is a need to assess the economic benefit of community based dementia screening programs.

Materials and Methods.

Markov model simulations were generated using data obtained from a community based dementia screening program over a one-year period.

The models simulated yearly costs of caring for patients based on clinical transitions beginning in pre dementia and extending for 10 years.

Results.

A total of 93 individuals (74 female, 19 male) were screened for dementia and 12 meeting clinical criteria for either mild cognitive impairment (n=7) or dementia (n=5) were identified.

Assuming early therapeutic intervention beginning during the year of dementia detection, Markov model simulations demonstrated 9.8% reduction in cost of dementia care over a ten-year simulation period, primarily through increased duration in mild stages and reduced time in more costly moderate and severe stages.

Discussion.

Community based dementia screening can reduce healthcare costs associated with caring for demented individuals through earlier detection and treatment, resulting in proportionately reduced time in more costly advanced stages.
