摘要
目的了解北京市西城区乙肝病毒感染相关疾病的直接经济负担及其影响因素。方法按照随机抽样的方法,对西城区乙肝病毒感染相关疾病的患者进行乙肝患病费用调查,了解乙肝病毒感染的人均直接经济负担,运用单因素方差分析,筛选可能的影响因素;使用Gamma模型进一步明确实际影响直接经济负担的因素。结果有效调查问卷316份,所有对象1年的人均直接经济负担为22730.4元,其中直接医疗费用22042.7元,非直接医疗费用687.7元;直接医疗费用中住院费用比例最高(17528.0元,79.52%);直接经济负担与家庭年收入之比为19.32%。Gamma模型拟合结果显示所患疾病、职业和治疗场所是直接经济负担的影响因素。结论直接医疗费用占直接经济负担的绝大部分,乙肝病毒感染相关疾病给患者及家庭造成了沉重的经济负担,患者所患疾病、职业状况、治疗医院级别是主要的影响因素,通过降低住院治疗费用、延缓疾病进展可以减轻直接经济负担。Gamma模型在此类问题的统计分析中有一定的应用价值和借鉴意义。
Objective To understand direct economic burden of diseases related to hepatitis B viral（HBV） infection in Xicheng district and its relevant factors.Methods A cross-sectional study was carried out in patients with HBV-infection selected randomly with questionnaire to analyze their direct economic burden.One-way analysis of variance was used to explore potential influencing factors by Gamma model fitting.Results A total of 316 patients were recruited in the study.Annual direct cost for them was 22 730.4 yuan RMB per capita,including direct medical and non-medical cost of 22 042.7 and 687.7 yuan RMB,respectively.Gamma model fitting showed that types of disease,occupation and location for treatment of the patients were the main influencing factors for direct economic burden.Conclusion HBV infection related diseases caused heavy economic burden to the patients and their families and direct medical cost accounted for majority of it.Type of disease,occupation and location for treatment of the patients are main influencing factors for direct economic burden.It can be reduced by lowering expenditure for treatment at hospitals and delaying progression of the disease.Gamma model fitting can be used in such analysis for direct economic burden.
