The objectives of this research are to determine (1) the providers' unit costof medical check-up for the elderlies by type of health care services eachindividual, (2) the providers' total cost of medical check-up for elderly, (3) theproviders' total cost of medical check-up for the three common chronic illnessesamong the elderlies namely: hypertension, diabetes mellitus and ischemic heartdisease and (4) the study will also determine the cost recovery ratio of the medicalcheck-up cost in terms of providers' unit cost by each type of health care services.It will also attempt to estimate the cost for medical check-up of the elderlies andits' sufficiency in relation to the forecasted increases of the population between2000-2002. This study is a descriptive study about the cost of medical check-up atChulalongkorn hospital. The study compares the cost of Chulalongkorn's medicalcheck-up programme with the World Health Organization standard medical check-upprogramme. It then went on to compare the Chulalongkorn medical check-up programmefor three illnesses namely: hypertension, diabetes mellitus, and ischemic heartdisease with the retrospective programme of three independent health establishments.The study also conducted a retrospective data collection of medical check-up costfrom secondary data sources at Chulalongkorn hospital during 1996-1997. The data werethen analysed into direct and indirect cost, which were then in turn disaggregatedinto labor cost, equipment cost, material cost, capital cost, public utility cost andthe cost for testing the accuracy standard of equipments. The study found that the total medical check-up cost of each individual elderlyis 796.61 baht. However in terms of the three selected illnesses the total medicalcheck-up cost were 220.34 baht for hypertension, 212.26 baht for diabetes mellitusand 341.29 baht for ischemic heart disease. This study found the cost recovery ratiofor Chulalongkorn hospital to be 1.10. Based on the estimated forecast of populationincreases between 1990-2010 done by the population division of the National Economicsan Social Development Board, which put the annual population increase at 173,720person, the study then estimated medical check-up cost of elderlies for the year1998. Based on that estimate, the study then uses the mentioned forecasted populationincrease to estimate the medical check-up cost for the elderlies in the threeconsecutive years of 2000-2002, assuming the various scenarios of how many times ofmedical check-up will be conducted each year for each individual elderly and whatkind of medical programme used. The estimated cost of the three years were found tobe 1,555,796,872 baht, 1,598,935,677 baht and 1,644,364,356 baht respectively.Conclusively, it is expected that the result of the study will provide healthplanners some guidelines of how we could contain the cost of medical check up for theelderlies or determine the charge for each particular check-up activities that can beregarded as appropriated for future circumstances. The result of the study shouldalso provide some policy implications of whether it is appropriate to subjectelderlies to medical check-up programme or not, so that medical cost of treating thementioned chronic illnesses could be avoided and contained.
