Patient Information Systems are digital platforms used by healthcare providers to manage patient data efficiently. These systems store essential information such as medical history, treatment plans, and medication records, allowing for quick access and better coordination of care. They help improve patient safety and streamline administrative tasks. These systems often integrate with other healthcare technologies, such as electronic health records (EHRs) and telemedicine platforms. By centralizing patient information, they facilitate communication among healthcare professionals and enhance the overall quality of care. Additionally, they support compliance with regulations like the Health Insurance Portability and Accountability Act (HIPAA).
