Li et al. (2015) proposed a web-based hospital information management system using B/S architecture. They highlighted the advantages of B/S architecture, such as platform independence, easy maintenance, and scalability.

Wang et al. (2016) presented a comparative study of B/S and C/S (Client/Server) architecture for hospital information management systems. They concluded that B/S architecture is more suitable for large-scale hospitals due to its centralized management and reduced hardware requirements.

Chen et al. (2017) investigated the security issues in B/S-based hospital information management systems. They emphasized the importance of implementing robust security measures, including encryption, access control, and intrusion detection, to protect sensitive patient data.

Zhang et al. (2018) proposed a cloud-based hospital information management system using B/S architecture. They discussed the benefits of cloud computing, such as cost-effectiveness, scalability, and real-time data access, for healthcare institutions.

Liu et al. (2019) conducted a usability evaluation of B/S-based hospital information management systems. They found that user satisfaction and system efficiency can be improved by incorporating user-friendly interfaces, intuitive navigation, and personalized features.

Yang et al. (2020) explored the integration of artificial intelligence (AI) technologies in B/S-based hospital information management systems. They discussed the potential applications of AI, such as medical diagnosis, predictive analytics, and personalized treatment recommendations, in improving healthcare delivery.

Xu et al. (2021) investigated the challenges and opportunities of adopting B/S architecture in rural healthcare settings. They highlighted the potential of B/S-based hospital information management systems to overcome resource constraints and improve healthcare access in remote areas.

Zhang et al. (2022) proposed a mobile-based extension to the B/S architecture for hospital information management systems. They discussed the benefits of mobile access, such as real-time data entry, remote consultations, and improved communication between healthcare providers and patients.
