Many Veterans who are hospitalized with heart failure do not receive all the recommended heart medications at the right doses before they leave the hospital or in the weeks following discharge. This study tests whether a team of clinical pharmacists and cardiologists, working virtually, can improve heart failure medication prescribing for Veterans at VA medical centers. The pharmacist and cardiologist team reviews patient records and provides recommendations to the treating doctors and primary care providers caring for Veterans with heart failure. The goal is to increase use of guideline-recommended medications, which have been shown to improve survival, reduce hospitalizations, and improve quality of life.

Heart failure with reduced ejection fraction (HFrEF) affects a large proportion of Veterans and isa leading cause of hospitalization and death. Clinical guidelines recommend four classes of medications (commonly called "quadruple therapy") that improve survival and reduce hospitalizations, yet 42% of Veterans hospitalized with heart failure do not receive all recommended medications at discharge. This study implements a virtual pharmacist and cardiologist team (hub) that provides digital consultation to hospitalists and primary care providers (spoke) at VA medical centers regarding use of guideline-directed medical therapy (GDMT) during hospitalization and the post-discharge period. The pharmacist/cardiologist team identifies eligible Veterans using a VA hospital-specific dashboard, reviews electronic health records, and places digital consultation notes with individualized medication recommendations, safety surveillance information, and out-of-pocket medication cost data. The intervention also incorporates identification of Veterans hospitalized in VA-paid community care settings. Veterans hospitalized with heart failure in community hospitals within the preceding 3 months are identified via VA-paid community care claims data, and actionable recommendations are provided through the VA electronic health record or by facsimile to community providers. Six VA medical centers served by Clinical Resource Hubs in VISNs 4, 16, 17, 19, and 23 are participating. Sites are randomized to one of three implementation waves in a cluster-randomized stepped-wedge design, with implementation occurring every 6 months at two sites per wave. This design allows estimation of intervention effects using both within- and between-site comparisons while controlling for secular trends. A difference-in-differences analytic approach with covariate-constrained randomization is used to estimate causal effects. The primary effectiveness outcome is change in GDMT optimization score from admission to 14 days after discharge. Secondary effectiveness/safety outcomes include mortality, heart failure readmission, and medication-related adverse events at 90 days. Implementation outcomes are assessed using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework and include fidelity to identification of at-risk Veterans, provision of recommendations,, outpatient follow-up rates, and barriers and facilitators to implementation Additional outcomes derived from the RE-AIM framework will also be captured.
