Structure Equation Model Analysis about Urban Hospital Medical Cost Increase Influence Factors

Objective To provide decision-making basis for solving the medical expenses overgrowth problem by quantitative research of increases influence factors in urban hospital medical treatment fee and the factor interactions.Methods Using the observation variable structure equation model to analyze rising medical costs influence factors.Results ① The government reducing financial input would lead medical costs rise,financial investment increase 1 billion yuan,resulting in per capita medical costs decline 0.334 yuan and urban hospital medical costs reduced total 39.6 billion yuan.② Medical treatment cost growth is irrational.GDP and retail price index is growing,but medical treatment charge is fallen.③ Medical expenses growth is related to the income level and the patient characteristics,per capita income increase one yuan,the per capita medical expenses growth 0.088 yuan.the percentage of the number of admissions by number of clinical visits is higher,medical expenses growth is lower;④ Medical treatment fee increases is irrelevant with the work efficiency of doctors.Conclusion Controlling medical expense rise mainly controls medical treatment fee increases.The government financial input on health service should be keeping growth simultaneously with GDP and slightly higher level,increasing input growth around 10% each year.
