This question belongs to Measurement and Analysis because CPXP expects patient experience professionals to use valid data sources and share feedback in ways that inform improvement. HCAHPS stands for Hospital Consumer Assessment of Healthcare Providers and Systems and is the first national, standardized, publicly reported survey of patients’ perspectives of hospital care. That makes B the correct answer. In CPXP practice, HCAHPS is valuable because it helps organizations identify performance gaps, compare results over time, and connect patient feedback to improvement priorities. Options A, C, and D are incorrect because they describe other organizational tools, not the core purpose of HCAHPS. In short, HCAHPS is a foundational measurement source for understanding inpatient experience from the patient’s perspective and turning that information into action.
