运用“医保、医疗、医药三方发展有失协调的恶性循环模型”定量方法,测算了中等发达地区医疗费用增长的各方责任。研究发现中等发达地区次均医疗费用过快增长中,诊疗人次萎缩的作用超过了财政投入相对萎缩的作用,提示在中等发达地区必须将提高医疗保障水平作为恢复医院、医保和医药三方协调关系的切入点,其合理方式是社会性医疗保险制度的贯彻落实到位,其前提是对医疗费用实行“总量控制”,促进其增长保持在合理水平。 Using the quantitative method of “violating circulation model of medical insurance, medical care, and medical tripartite development inconsistency,” the parties’ responsibilities for the increase of medical expenses in the medium-developed regions were calculated. The study found that in the moderately developed regions where the average cost of medical care increased too rapidly, the effect of shrinkage in the number of visits and medical treatment exceeded the relative shrinkage of financial input, suggesting that the improvement of medical security must be used as a tripartite coordination relationship between hospitals, medical insurance, and medicine in middle-developed regions. The point of entry is that the rational way is to implement the social medical insurance system in place. The premise is to implement “total amount control” for medical expenses and promote its growth to maintain a reasonable level.
