In the described measure, what is being measured over the total population?

• A. Adherence rates
• B. Utilization rates
• C. Satisfaction scores
• D. Cost per patient

Answer: (A)

Adherence rate is measured across the entire defined population, expressing the proportion of all patients who follow the prescribed therapy. In this type of measure, the denominator is the total number of patients in the population (for example, all patients prescribed the medication), and the numerator is the subset who are adherent (e.g., those who refill on time or take the medication as prescribed). This yields a percentage that reflects how well the treatment plan is being followed across the whole group.

For context, utilization rates, satisfaction scores, and cost per patient are different kinds of metrics: utilization looks at how often services are used, satisfaction reflects patient experience (often from surveys), and cost per patient reports average spending. The described measure, by focusing on the proportion adherent within the entire population, specifically calibrates performance of ongoing therapy management across that group. Example: 150 adherent patients out of 200 prescribed a medication gives an adherence rate of 75%.
