Abstract

Coronary artery disease, diabetes and high blood pressure are leading causes of illness and become major public health problems in Thailand. Previous research shows a clear-cut

relationship between coronary heart disease, diabetes and high blood pressure. In the past decade, thousands of Thai patients suffer from these diseases. The objectives of the current

study are to examine the overall cost of treatment for a variety of treatment modalities for

coronary heart disease, diabetes and high blood pressure, and estimate the number of patients and the treatment cost of these diseases during 2013-2017. Statistical methods for time series

are used in analyzing and forecasting the series data obtained from national health statistics reports of Thailand. Trend analysis suggests a linear increase in the number of coronary heart

disease patients as given in a regression equation, Yt = 43913 + 15413*t. A nonlinear trend is found in the number of diabetes and high blood pressure patients as given in equations, Yt = 107

/ (7.43749 +66.6098 * (0.841320t)), and Yt = 107 / (1.41468 +75.7866 * (0.835007t)), respectively.

Monte Carlo Simulation is used in sensitivity analysis of monetary inflation, which is a rise in the overall cost of medical treatment. Trend analysis suggests an increased cost of high pressure

treatment from 1.17% to 1.84% GDP during 2013-2017.
