Design of a multifaceted strategy based on automated text messaging in patients with recent heart failure admission.

Abstract

AimsTo evaluate a telemonitoring strategy based on automated text messaging and telephone support after heart failure (HF) hospitalization.Methods and resultsThe MESSAGE‐HF study is a prospective multicentre, randomized, nationwide trial enrolling patients from 30 clinics in all regions of Brazil. HF patients with reduced left ventricular ejection fraction (<40%) and access to mobile phones are eligible after an acute decompensated HF hospitalization. Patients meeting eligibility criteria undergo an initial feasibility text messaging assessment and are randomized to usual care or telemonitoring intervention. All patients receive a HF booklet with basic information and recommendations about self‐care. Patients in the intervention group receive four daily short text messages (educational and feedback) during the first 30 days of the protocol to optimize self‐care; the feedback text messages from patients could trigger diuretic adjustments or a telephone call from the healthcare team. After 30 days, the frequency of text messages can be adjusted. Patients are followed up after 30, 90, and 180 days, with final status ascertained at 365 days by telephone. Our primary endpoint is the change in N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) levels after 180 days. Secondary endpoints include changes in NT‐proBNP after 30 days; health‐related quality of life, HF self‐care, and knowledge scales after 30 and 180 days; and a composite outcome of HF hospitalization and cardiovascular death, adjudicated by a blinded and independent committee.ConclusionsThe MESSAGE‐HF trial is evaluating an educational and self‐care promotion strategy involving a simple, intensive, and tailored telemonitoring system. If proven effective, it could be applied to a broader population worldwide.
