This study examined the impact of HF telemonitoring on unplanned hospitalization. Patients admitted to the hospital for HF and who agreed to use the non-invasive telemonitoring system were candidates in the study. It measured body weight, blood pressure and heart rate each day, and an alert was made if they exceeded a certain limit. The study contained data from 97 patients. The primary endpoint was a composite of unplanned cardiovascular hospitalization and all-cause mortality. Patients were classified into three groups: hospitalized (for any of the endpoints) during the telemonitoring period (Group 1 ["monitoring failure"]), hospitalized after the telemonitoring period (Group 2), and not hospitalized (Group 3). Median telemonitoring period was 222 [141, 518] days. The number of patients in each group was 18, 18, and 61. Patients in Group 1 were older (75 vs. 63 years, p < 0.001) and had poorer estimated glomerular filtration rate (31 vs. 62 mL/min/1.73m2, p < 0.001) than those in Group 3. Length of hospitalization periods at the endpoint tended to be longer in Group 1 than Group 2 (8.5 [6, 14] vs. 5 [4, 10] days, p = 0.084). If heart failure telemonitoring fails to prevent unplanned hospitalization, the length of that hospitalization period may be longer than if the unplanned hospitalization could have been prevented.
