The Electronic Healthcare Administrative Tool (eHAT) is a scalable, web-based hospital information system that operates independently of platform constraints and is built using open-source technology. This comprehensive system includes 40 distinct modules designed to optimize the administrative, operational, revenue, and clinical workflows within a hospital setting. Specifically tailored for large, multi-specialty, and enterprise-level hospitals, eHAT Enterprise serves as an all-in-one solution for hospital management needs. Additionally, the eHAT Laboratory Information System enhances lab operations by automating previously manual tasks, thereby increasing overall efficiency. This software supports the entirety of lab processes, from sample collection to reporting, which encompasses the recording, management, storage, and tracking of critical data. To ensure precise tracking, we employ barcodes for creating and updating audit logs, maintaining a chain of custody that automatically indicates the location of samples at every stage of their journey. Overall, eHAT not only streamlines hospital operations but also significantly improves the accuracy and accountability of laboratory processes.
