Introduction: Reduced ejection fraction (REF) in patients is prevalent, utilizing substantial health care resources. Goal Directed Therapy (GDT) reduces hospitalization, morbidity, and mortality but use is suboptimal. Care in subspecialty clinics following discharge reduces readmission, but is not scaled for longitudinal care of the larger REF population. Canadian guidelines support integration of primary, specialist, and non-physician care in systems to improve outcomes.

Hypothesis: A protocol-guided intervention will achieve high rates of GDT for REF patients in a community health care setting.

Goal: To evaluate a pragmatic quality-of-care intervention to achieve GDT for REF patients and assess barriers to GDT.

Methods: Patients referred for imaging and cardiology consultation at a community facility (Jan 1/15-Dec 31/22) were screened. Patients with LVEF <41% on echocardiogram were included if their cardiologist consented to study protocol GDT and were enrolled at the next scheduled, usual care cardiologist visit. 2 project nurses confirmed patient status and assisted GDT management using medical directives at 9 protocol-specified visits between usual care visits over 32 weeks. The primary target was achieving GDT or maximally tolerated GDT (>0 mg). A secondary endpoint, clinical inertia, was defined as not achieving GDT due to physician or patient choice.

Results: 864 patients (13 cardiologists) participated: median age 71 (28-102) years, diabetes 25%, hypertension 60%, atrial fibrillation 22%. At intake: NYHA class ≥2 (60%), EF <30% (45%), 30-35% (27%), 36-40% (29%), REF etiology ischemic (47%), non-ischemic (43%), mixed (10%). The majority achieved GDT in each class; inertia, not intolerance predominantly accounted for those who did not achieve GDT.

Conclusion: This pragmatic community-based intervention achieved high rates of GDT that could improve longitudinal care for REF patients, and is potentially scalable and generalizable.
