Clinical Decision Support (CDS) tools are a vital component of modern Electronic Prescribing and Medicines Administration (EPMA) and wider Electronic Patient Record (EPR) systems. When designed and implemented well, CDS helps clinicians make safer, faster, and more evidence-based decisions, from alerting them to drug interactions, to guiding appropriate prescribing, to nudging better clinical practices. This learning program explores the role of CDS in improving patient safety and enhancing digital healthcare workflows. It covers what CDS is, the different types and levels of decision support, and how these systems are built into EPMA/EPR platforms. We'll look at best practices, real-world NHS examples, and the balance between useful support and alert fatigue. You'll gain insight into: - The underlying logic behind CDS tools - How rules and logic are configured in EPMA systems - How CDS can be aligned with clinical governance and safety standards - The risks of poorly designed CDS (e.g. overrides, false alerts, or inaction) - Future trends like AI-driven decision support Whether you're a digital pharmacist, informatics lead, or a clinician involved in EPMA governance, this program will equip you with the understanding to advocate for, and design, better CDS functionality that protects patients without overwhelming staff.
