Examining the Influence of Optimal Guideline-Directed Medical Therapy on Patient-Reported Outcomes in Adults With Heart Failure.

Background: Multidrug, guideline-directed medical therapy (GDMT) improves mortality and hospitalizations for heart failure (HF), but little is known about how optimization of multidrug GDMT influences patient-reported outcomes. Trials of single GDMT medications demonstrate improvements in patient-reported outcomes; however, the effect of the multidrug GDMT regimen on patient-reported outcomes is unclear.

Objective: The objective of this study is to determine how multidrug optimization during a multidisciplinary, advanced practice provider HF clinic impacted patient-reported symptoms and quality of life in adults with HF.

Methods: This retrospective cohort study examined patient-reported outcomes at baseline and 12 weeks during a multidrug GDMT optimization clinic for HF. Outcomes were compared across time and male and female sex. Quality of life was measured with the EQ5D. Symptoms were measured using the PROMIS-29 and PROMIS-Dyspnea Severity score. Descriptive statistics describe sample characteristics. Paired and independent t tests were used for comparisons.

Results: Of 301 adults with HF enrolled in a clinic, 101 completed patient-reported outcome measures at baseline and 12 weeks. Patients (predominantly White/Caucasian males; mean age, 59 years) reported significant improvement in the EQ5D domains of mobility and performance of usual activities, and PROMIS-29 subscales for physical function, fatigue, and ability to participate in social roles. Sex differences were noted for pain and depression, with females reporting improved pain and males reporting slightly less depression.

Conclusions: Multidisciplinary, advanced practice provider-led optimization clinics can promote optimization of multidrug GDMT that can improve patient-reported outcomes in adults with HF. Future studies are needed to comprehensively examine sex differences in patient-reported response to GDMT and patient-reported response to updated, "quadruple-therapy" GDMT recommendations.
