Abstract
Background
The natural history of heart failure is a progressive decline and recurrent hospital admissions. New strategies to timely detect decompensations are needed. The use of telemonitoring in heart failure is inconsistent.
Objectives
This study aimed to evaluate the impact of this telemonitoring program (TMP) in hospitalizations and emergency department admissions.
Methods
This is a retrospective observational study, that analyzed data of all the patients who enrolled in the TMP program from January 2018 to December 2019. Demographic, clinical, and TMP-related data were collected. The number of hospitalizations and emergency department admissions from the year before and after enrollment were compared, using the Wilcoxon test. A two-sided p<0.05 was considered significant.
Results
A total of 39 patients were enrolled, with a mean age of 62.1 ± 14 years and a male predominance (90%). The most common causes of heart failure were ischemic and dilated cardiomyopathy. The mean ejection fraction was 30% and the median time of disease duration was 84 months (IQR 33-144). Patients who were enrolled for less than one month were excluded, with a total of 34 patients analyzed. Patients were followed in the TMP for a median of 320 days. The number of emergency department admissions was reduced by 66% (p<0.001), and the number of hospitalizations for heart failure was reduced by 68% (p<0.001). The TMP had no impact on the number of hospitalizations for other causes.
Conclusions
This trial suggests that a TMP could reduce health service use in patients with heart failure.
