Abstract:

The ‘Internet plus Medicine’ platform is an important measure to deepen the reform of the medical system and promote the rational allocation of medical resources in the context of new medical reform. In order to rationally allocate high-quality medical resources and funds in the less developed areas and promote the “Internet plus Medicine” platform and the income of medical institutions in less developed areas, in this paper, the ‘Internet plus Medical’ platform composed of secondary hospitals, tertiary hospitals, and platform operators is considered, and the cooperative operation mechanism of the platform is studied based on pricing strategy. The platform operator provides two types of payment methods and corresponding payment prices for secondary and tertiary hospitals respectively: annual payment and per patient visit payment. The revenue model of each participant in the ‘Internet plus Medicine’ platform is established, and the participation strategies of secondary and tertiary hospitals are obtained based on the optimization theory using the integer programming method, and the participation strategies of hospitals are incorporated into the revenue model of the platform operator. On the basis of meeting the participation thresholds of secondary and tertiary hospitals, the pricing strategy of the platform operator is developed using the genetic algorithm. The impact of requesting the assistance probability and revenue sharing coefficient of other hospitals on the participation and platform revenue of secondary and tertiary hospitals is analyzed. The results show that in the operation of the ‘Internet plus Medicine’ platform, both secondary and tertiary hospitals preferred to use the annual payment method, and the cooperative operation mechanism established by the platform operator could replace the financial subsidies from government agencies to realize the sustainable operation of the platform itself and promote the rational allocation of high-quality medical resources.

摘要：

“互联网+医疗”平台的搭建和推广是深化医疗体制改革、完善我国特色医疗卫生制度的重要举措，对推动优质医疗资源下沉具有重要意义。为了让优质医疗资源向欠发达地区倾斜，提高“互联网+医疗”平台参与度以及欠发达地区的医疗机构收益，综合考虑了由二级医院、三级医院和平台运营商三者组成的“互联网+医疗”平台，建立了“互联网+医疗”平台各参与方的收益模型。首先，基于整数规划法求得二级医院和三级医院的参与策略；然后，在满足二级和三级医院参与度阈值的基础上，以平台运营商收益最大值为目标，制定平台运营商定价策略；最后，分析了请求其他医院协助概率及收入分成系数对二级和三级医院的参与度与平台收益的影响。结果表明，在“互联网+医疗”平台的运营过程中，二级医院和三级医院均更倾向于使用按年付费的参与方式，平台运营商建立的合作运营机制能够代替政府机构资金补贴，实现平台自身可持续运营，推动优质医疗资源下沉。
