Heart Failure Optimization at Home to Improve Outcomes (Hozho): A Pragmatic Clinical Trial in Navajo Nation (Hozho)

December 16, 2024 updated by: University of Pennsylvania

Heart Failure Optimization at Home to Improve Outcomes (Hozho): A Pragmatic Clinic Trial of Telephone-Based GDMT Optimization in Navajo Nation

Heart failure causes significant morbidity and mortality, particularly in Navajo Nation. There are well-established evidence of improved mortality and lower heart failure hospitalizations with certain pharmacotherapies for heart failure with reduced ejection fraction (HFrEF). However, these medications are underutilized nationally, including in the Indian Health Service which is one important driver of poor heart failure outcomes. Therefore, as part of an EHR-based pragmatic clinic trial, we are implementing and testing a model that identifies American Indian HFrEF patients receiving care at one large Indian Health Service Site who meet clinical criteria for, but are not on appropriate therapy, and implements a model in patients are initiated and titrated on appropriate therapy over the phone with remote tele monitoring using home blood pressure cuff. We will evaluate the impact of this model to improve uptake of GDMT among HFrEF patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control
Usual care, control group
Active Comparator: Telehealth Model
Patient enrolled in the GDMT Telehealth HF improvement program in which hone BP cuff is provided and medication is initiated and titrated over the phone
Behavioral: EHR-based GDMT Optimization
Patients will be prescribed appropriate GDMT for HFrEF if they meet clinical criteria by the study team, appropriate lab work and follow up testing will be sent and followed up by the team. All recommendations and plans will be copied to primary care providers who can opt out if disagree, but also to improve telementoring to build clinical comfort.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
