基于二维码的电子诊疗卡系统的设计

目的构建一个以二维码作为电子诊疗卡替代医院传统诊疗卡的系统。方法依托医院微医疗平台,对患者唯一标识和时间戳进行MD5计算生成字符串,并以此内容生成二维码作为电子诊疗卡,同时对HIS进行相应改造,实现电子诊疗卡在全院的应用。结果利用时间戳和MD5签名生成二维码保证了电子诊疗卡加密的唯一性、时效性,医院每年节约成本5万元,患者每次就诊时间减少5 min,提升了患者满意度。结论本文构建的二维码电子诊疗卡系统,解决了使用实体诊疗卡过程中经常出现的忘带卡和重复办卡等问题,提高了医院服务质量,改善了患者就医体验。

Design of Electronic Medical Card System Based on Two-Dimensional Code

Objective To construct a system that uses two-dimensional code as medical card instead of traditional hospital medical card.Methods Based on the hospital micro medical platform,MD5 was used to calculate the unique identification and time stamp of patients to generate a string,and a two-dimensional code was generated based on this content as an electronic diagnosis and treatment card.At the same time,the corresponding transformation of HIS was carried out to realize the application of electronic diagnosis and treatment card in the whole hospital.Results The uniqueness and timeliness of encryption of electronic diagnosis and treatment card were guaranteed by using time stamp and MD5 signature to generate two-dimensional code.The annual cost of the hospital was saved by 50,000 yuan,and the time of each visit of patients was reduced by 5 minutes,which improved the satisfaction of patients.Conclusion The two-dimensional code electronic diagnosis and treatment card system constructed in this paper solves the problems such as forgetting to take the card and repeatedly handling the card in the process of using the entity diagnosis and treatment card,improves the service quality of the hospital,and improves the patients’medical experience.
