The purpose of this study is to suggest the resource allocation pattern forachieving equity for regional and general hospitals in Thailand and relation tohealth need population. The equity is defined as an equity of input and equity ofoutput for equal need, by studying only the regional and general hospitals recurrentbudget in the fiscal year 1997 under the responsibility of the Ministry of PublicHealth. The data collected from the Provincial Hospital Division and the Healthinsurance Office using descriptive analysis method and weighted populations. This study used four factors to apply analysis to the budget allocation namelythe hospital need in terms of input and in terms of output, the economic and socialfactor, the non- government budget and the number of people insured in socialsecurity scheme. The results of the study of 6 equations were also presented. Everyequation has 3 variables which represent social and economic data, non-governmentbudget and provincial population. First equation used variable of hospital need interms of input Second equation used variable of hospital need in terms ofoutput.-Third equation used variable of hospital need in terms of input includingnumber of referral. Fourth equation used variable of hospital need in terms of outputincluding number of referral. Fifth equation used variable of hospital need in termsof input including number of insure in social security scheme. Sixth equation usedvariable of hospital need in terms of output including number of social securityscheme. The analysis showed that the weighted populations was the major basis of theactual budget allocation for regional and general hospitals at present. The 6patterns in this study is one concept of equitable allocation. The factors used inthe 6 patterns have similar influence, the weighted populations value for eachhospitals in the 6 patterns were not much different due to the formulas used in each.equations. However, the variables in each patterns have both advantages anddisadvantages.
