Development and its applicability of cost of illness study

Abstract

Cost of Illness (COI) study is a simple and easy method that measures burden of disease as monetary value. This method has been coming under criticism because it covers only the cost without considering outcome, and it is unclear who is to pay the cost. But COI study is simple to calculate compared with other methods for economic evaluation, and it has been used for political decision making in countries such as U.S.A. and New Zealand. COI study has established its position in spite of many criticisms by securing its credibility, repeatability and comparability rather than modifying its theoretical framework.
