Healthcare data analytics has become a core competency for nurses practicing in today's technology-driven clinical environments. This learning activity explores how nurses interact with and contribute to healthcare data systems, including electronic health records, predictive analytics, early warning tools, artificial intelligence, and remote patient monitoring technologies. Learners will examine the relationship between accurate nursing documentation and the integrity of clinical decision support systems, consider the ethical dimensions of data privacy, algorithmic bias, and data governance, and identify practical strategies for building digital literacy and advocating for effective, equitable health information systems at the bedside and beyond.
