University Hospital has the messaging technology to securely route an alert for a patient's possible drug interaction or abnormal lab result to the appropriate physician's pager number. Which one of the following is the medical staff using?

• A. Electronic Health Record
• B. Clinical information system
• C. Pharmacy information system
• D. Laboratory information system

Answer: (B)

The scenario is about a system that supports real-time clinical communication and alerts across the care team. A clinical information system is designed to integrate data from multiple clinical domains (pharmacy, lab, patient records) and to support workflows like order entry, results reporting, decision support, and secure messaging. Being able to route an alert about a potential drug interaction or an abnormal lab result to the physician’s pager is exactly the kind of cross-domain, timely notification functionality that a clinical information system provides.

An electronic health record mainly serves as a comprehensive record of patient data and may include alerts, but its primary role is documentation and viewing information. A pharmacy information system focuses on medication management, and a laboratory information system focuses on lab data and workflows; neither alone is designed to handle the integrated, physician-to-device alerting across multiple domains that the scenario describes.
