Background: Heart failure (HF) is a chronic, progressive medical condition. Evidence suggests that guideline-directed medical therapy improves both morbidity and mortality in patients with HF with reduced ejection fraction when properly optimized. Unfortunately, many patients do not receive optimized therapy, highlighting the need to optimize clinicians’ methods to more effectively and efficiently initiate and titrate medical therapy.
Methods: This single-center, retrospective study evaluated the rates of drug interventions prompted by the home telehealth monitoring program for veterans with HF with reduced ejection fraction. Rates of drug interventions were evaluated among those who enrolled and those who did not enroll in the program.
Results: There were 20 drug-related interventions in the home telehealth group compared with 11 interventions for the control group. One HF-related hospitalization occurred in the home telehealth program group compared with 6 in the control group.
Conclusions: This study demonstrates the potential of home telehealth to optimize veterans’ medication regimens and to reduce HF-related hospitalizations. It also provides an additional catalyst to further develop home telehealth services specifically targeted at drug therapy initiation and optimization in patients with HF with reduced ejection fraction.
Heart failure (HF) is a chronic, progressive condition that is characterized by the heart’s inability to effectively pump blood throughout the body. In 2018, approximately 6.2 million US adults had HF, and 13.4% of all death certificates noted HF as a precipitating factor.1 Patients not receiving appropriate guideline-directed medical therapy (GDMT) face a 29% excess mortality risk over a 2-year period.2 Each additional GDMT included in a patient’s regimen significantly reduces all-cause mortality.3
The Change the Management of Patients with Heart Failure (CHAMP) registry reports that only about 1% of patients with HF are prescribed 3 agents from contemporary GDMT at target doses, highlighting the need for optimizing clinicians’ approaches to GDMT.4 Similarly, The Get With The Guidelines Heart Failure Registry has noted that only 20.2% of patients with HF with reduced ejection fraction (HFrEF) are prescribed a sodium-glucose cotransporter 2 inhibitor (SGLT2i) following hospital discharge for HFrEF exacerbation.5 Overall, treatment rates with GDMT saw limited improvement between 2013 and 2019, with no significant difference between groups in mortality, indicating the need for optimized methods to encourage the initiation of GDMT.6
Remote monitoring and telecare are novel ways to improve GDMT rates in those with HFrEF. However, data are inconsistent regarding the impact of remote HF monitoring and improvements in GDMT or HF-related outcomes.6-10 The modalities of remote monitoring for GDMT vary among studies, but the potential for telehealth monitoring to improve GDMT, thereby potentially reducing HF-related hospitalizations, is clear.
Telemonitoring has demonstrated improved participant adherence with weight monitoring, although the withdrawal rate was high, and has the potential to reduce all-cause mortality and HF-related hospitalizations.11,12 Telemonitoring for GDMT optimization led to an increase in the proportion of patients who achieved optimal GDMT doses, a decrease in the time to dose optimization, and a reduction in the number of clinic visits.13 Remote GDMT titration was accomplished in the general patient population with HFrEF; however, in populations already followed by cardiologists or HF specialists, remote optimization strategies did not yield different proportions of GDMT use.14 The aim of this study was to assess the impact of the home telehealth (HT) monitoring program on the initiation and optimization of HF GDMT among veterans with HFrEF at the Veterans Affairs Ann Arbor Healthcare System (VAAAHS) in Michigan.
