MCQ Quiz: Health-Related Quality of Life

Welcome, PharmD students, to this essential MCQ quiz on Health-Related Quality of Life (HRQoL)! Beyond traditional clinical markers, understanding the patient’s own perspective on their well-being is crucial in modern healthcare. HRQoL assessment captures the impact of disease and treatment on physical, mental, emotional, and social aspects of a patient’s life. This quiz will test your knowledge on defining HRQoL, the different types of instruments used for its measurement (generic vs. disease-specific), how utilities are derived for pharmacoeconomic analyses like CUA, and the importance of patient-reported outcomes. Let’s explore this vital component of patient-centered care!
