Which of the following are major types of information systems in healthcare?

The major types of information systems in healthcare are specifically those that directly support the various functions and activities within healthcare organizations and enhance patient care. Electronic Health Records (EHR) are crucial for storing patient information, enabling streamlined access to medical histories, treatment plans, and other critical data. Hospital Management Systems facilitate operational management by integrating multiple functions, including patient admissions, billing, and resource management, leading to improved administrative efficiency. Telemedicine Systems enable healthcare providers to deliver care remotely, which is particularly important for increasing access to healthcare services, especially in underserved areas or during public health emergencies.

These specific systems are fundamental to the modern healthcare infrastructure as they contribute to improved clinical outcomes, operational efficiency, and patient engagement. On the other hand, options that focus on different areas like human resources, customer relationship management, or inventory management, while important in their respective contexts, do not specifically address the core functions of healthcare delivery and management. They may play supportive roles but do not constitute the primary information systems utilized in healthcare practice.
