BACKGROUND
Health price inflation rate is different from increasing in health expenditures. Health expenditures contain both quantity and prices but inflation rate contains prices. This study aimed to determine the factors that affect the Inflation Rate for Health Care Services (IRCPIHC) in Iran.
METHODS
We used Central Bank of Iran data. We estimated the relationship between the inflation rate and its determinants using dynamic factor variable approach. For this purpose, we used STATA software.
RESULTS
The study results revealed a positive relationship between the overall inflation as well as the number of dentists and health inflation. However, number of beds and physicians per 1000 people had a negative relationship with health inflation.
CONCLUSION
When the number of hospital beds and doctors increased, the competition between them increased, as well, thereby decreasing the inflation rate. Moreover, dentists and drug stores had the conditions of monopoly markets; therefore, they could change the prices easier compared to other health sectors. Health inflation is the subset of growth in health expenditures and the determinants of health expenditures are not similar to health inflation.
背景
医疗价格通胀率不同于医疗支出的增长。医疗支出包含数量和价格两个方面，而通胀率仅包含价格因素。本研究旨在确定影响伊朗医疗服务通胀率（IRCPIHC）的因素。
方法
我们使用了伊朗中央银行的数据。我们采用动态因子变量法估计通胀率与其决定因素之间的关系。为此，我们使用了STATA软件。
结果
研究结果显示，总体通胀以及牙医数量与医疗通胀之间存在正相关关系。然而，每千人的病床数和医生数量与医疗通胀呈负相关关系。
结论
当医院病床数和医生数量增加时，他们之间的竞争也会加剧，从而降低通胀率。此外，牙医和药店处于垄断市场环境；因此，与其他医疗部门相比，他们更容易改变价格。医疗通胀是医疗支出增长的一部分，医疗支出的决定因素与医疗通胀并不相同。
