A PMHNP is managing a panel of 85 patients with major depressive disorder at an outpatient psychiatric practice. The clinic is transitioning to a measurement-based care model and asks the PMHNP to implement systematic outcome tracking. After three months, the PMHNP reviews her data and finds that 40% of her patients have achieved a 50% or greater reduction in PHQ-9 scores, 25% have achieved remission (PHQ-9 less than 5), and 35% have shown minimal or no improvement. Which of the following represents the most appropriate interpretation and use of these outcome data?
