The healthcare domain in India is rapidly evolving with multiple healthcare and Hospital Management Information Systems (HMIS) being deployed at various medical facilities. However, aggregation and analytics on standardized healthcare datasets is possible only when these isolated systems are integrated on a common platform for exchange of patient Electronic Health Record (EHR) and data interoperability is facilitated. This presents a challenge due to the heterogeneous nature of systems and operational or policy-based restrictions in integrating them. In this paper, we present a distributed HMIS architecture which allows for integration of multiple stand-alone HMIS on a common platform that enables interoperability via EHR sharing and aggregation of standardized data for enabling analytics and visualization. Additionally, the proposed architecture also facilitates local, standalone deployments at primary medical facilities which are configured for local requirements and also synchronize essential datasets at the central node for enabling analytics. The deployment of this distributed architecture has also enabled uniformity and transparency in healthcare service delivery, while also facilitating better management and monitoring of available resources for efficient administration and governance.

具有同步EHR的医院管理系统的分布式体系结构

印度的医疗保健领域正在迅速发展，并在各种医疗机构中部署了多个医疗保健和医院管理信息系统（HMIS）。但是，仅当将这些隔离的系统集成在用于交换患者电子病历（EHR）的通用平台上并且促进了数据互操作性时，才可以对标准化医疗数据集进行汇总和分析。由于系统的异质性以及集成中基于操作或基于策略的限制，因此这带来了挑战。在本文中，我们提出了一种分布式HMIS体系结构，该体系结构允许在一个通用平台上集成多个独立的HMIS，该体系结构通过EHR共享和标准化数据的聚合实现互操作性，从而实现分析和可视化。另外，所提出的体系结构还促进了在主要医疗机构中的本地独立部署，这些部署针对本地需求进行了配置，并且还同步了中心节点上的基本数据集以实现分析。此分布式体系结构的部署还使医疗服务交付具有统一性和透明性，同时还促进了对可用资源的更好管理和监控，以实现有效的管理和治理。
