This $247,417 federal Project Grant award from the National Heart, Lung, and Blood Institute (NHLBI) under the Cardiovascular Diseases Research program (CFDA 93.837) will fund the "Promoting Palliative Care for People with Heart Failure (P3HF) Pilot Study" at Yale University. The objective is to design and pilot test the P3HF clinical decision support (CDS) tool, which incorporates a 1-year mortality risk model to facilitate palliative care referrals for heart failure patients. The project will involve designing the CDS and an implementation package, then conducting a randomized pilot trial at two hospitals to evaluate the usability, acceptability, and preliminary effectiveness of the intervention on clinician referrals to palliative care and patient outcomes like advance care planning and hospital utilization. The award date is September 2, 2024, with a completion date of June 30, 2027. The findings from this pilot study will inform a subsequent larger-scale clinical trial on the P3HF intervention.
