Absence of appropriate hospitalization cost control for patients with medical insurance: a comparative analysis study
研究发现中国医保患者的住院费用高于自费患者，主要因住院天数更长、疾病类型、性别、年龄和婚姻状况等因素，建议加强政府监管和改革支付方式。
OBJECTIVE: Expose the weak loops in the Chinese medical insurance coverage and uncover hospitals' role of over-pricing hospitalized insured patients compared with those non-insured. METHODS: A multi-linear regression method was used to analyze hospitalization expense for insured and uninsured patients with uncomplicated acute appendicitis, cholecystitis, benign uterine tumors, and normal delivery. RESULTS: Hospitalization cost is higher among insured than uninsured patients due to longer hospitalization lengths of stay, type of disease (highest among cholecystitis patients), type of gender - females, old-aged people, and type of marital status - singles, as well as drugs expenses, surgical expenses, and other medical acts. CONCLUSION: Require a better government's supervision system over medical insurance expenses such as reforming methods of payments, building up new cost compensation mechanism, and unifying and stabilizing prices for each category of medicines.
