The public finance and foreign exchange crisis of the 1980s aggravated the unfavourable economic trends in many developing countries and resulted in budget cuts in the health sector. Policymakers, following the suggestions of World Bank experts, introduced user fees. Economic analysis of the demand for health care in these countries focused on the impact of price and income on health service utilisation. But the lesson to date from experiences in cost recovery is that without visible and fairly immediate improvements in the quality of care, the implementation of user fees will cause service utilisation to drop. For this reason, the role of quality of health care has been recently a subject of investigation in a number of health care demand studies. In spite of using the data from both households and facilities, recent studies are quite limited because they measure quality only by structural attributes (availability of drugs, equipment, number and qualifications of staff, and so on). Structural attributes of quality are necessary but not sufficient conditions for demand. A unique feature of this study is that it also considers the processes followed by practitioners and the outcome of care, to determine simultaneously the respective influence of price and quality on decision making. A nested multinomial logit was used to examine the choice between six alternatives (self-treatment, modern treatment at home, public hospital, public dispensary, for-profit facility and non-profit facility). The estimations are based on data from a statistically representative sample of 1104 patients from 1191 households and the data from a stratified random sample of 42 out of 84 facilities identified. The results indicate that omitting the process quality variables from the demand model produces a bias not only in the estimated coefficient of the "price" variable but also in coefficients of some structural attributes of the quality. The simulations suggest that price has a minor effect on utilisation of health services, and that health authorities can simultaneously double user fees and increase utilisation by emphasising improvement of both the structural and process quality of care in public health facilities.
20世纪80年代的公共财政和外汇危机加剧了许多发展中国家不利的经济趋势,导致卫生部门预算削减。政策制定者按照世界银行专家的建议,引入了使用者付费制度。对这些国家医疗保健需求的经济分析聚焦于价格和收入对医疗服务利用的影响。但迄今为止,成本回收方面的经验教训是,如果护理质量没有明显且相当迅速的改善,实行使用者付费制度将导致服务利用率下降。因此,医疗保健质量的作用最近成为一些医疗保健需求研究的调查主题。尽管近期研究使用了家庭和医疗机构两方面的数据,但这些研究相当有限,因为它们仅通过结构属性(药品供应、设备、工作人员数量和资质等)来衡量质量。质量的结构属性是需求的必要但不充分条件。本研究的一个独特之处在于,它还考虑了从业者遵循的流程以及护理结果,以同时确定价格和质量对决策的各自影响。采用嵌套多项logit模型来检验六种选择(自我治疗、在家接受现代治疗、公立医院、公共药房、营利性机构和非营利性机构)之间的选择。估计是基于来自1191个家庭的1104名患者的具有统计学代表性样本的数据,以及从84个已确定机构中分层随机抽取的42个机构的数据。结果表明,在需求模型中省略流程质量变量不仅会使“价格”变量的估计系数产生偏差,还会使质量的一些结构属性的系数产生偏差。模拟结果表明,价格对医疗服务利用率的影响较小,而且卫生当局可以在提高公共卫生机构护理的结构质量和流程质量的同时,将使用者付费提高一倍并增加利用率。
