Abstract

Background—: This study was designed to determine whether physician-led remote telemedical management (RTM) compared with usual care would result in reduced mortality in ambulatory patients with chronic heart failure (HF). Methods and Results—: We enrolled 710 stable chronic HF patients in New York Heart Association functional class II or III with a left ventricular ejection fraction ≤35% and a history of HF decompensation within the previous 2 years or with a left ventricular ejection fraction ≤25%. Patients were randomly assigned (1:1) to RTM or usual care. Remote telemedical management used portable devices for ECG, blood pressure, and body weight measurements connected to a personal digital assistant that sent automated encrypted transmission via cell phones to the telemedical centers. The primary end point was death from any cause. The first secondary end point was a composite of cardiovascular death and hospitalization for HF. Baseline characteristics were similar between the RTM (n=354) and control (n=356) groups. Of the patients assigned to RTM, 287 (81%) were at least 70% compliant with daily data transfers and no break for >30 days (except during hospitalizations). The median follow-up was 26 months (minimum 12), and was 99.9% complete. Compared with usual care, RTM had no significant effect on all-cause mortality (hazard ratio, 0.97; 95% confidence interval, 0.67 to 1.41; P =0.87) or on cardiovascular death or HF hospitalization (hazard ratio, 0.89; 95% confidence interval, 0.67 to 1.19; P =0.44). Conclusions—: In ambulatory patients with chronic HF, RTM compared with usual care was not associated with a reduction in all-cause mortality.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The TEN-HMS, TIM-HF and BEAT-HF trials showed that a remote telemonitoring intervention did not reduce heart failure hospitalizations and all-cause mortality.

    “TEN-HMS, TIM-HF and BEAT-HF trials showed that a remote telemonitoring intervention did not reduce HF hospitalizations and all-cause mortality68–70”
  • In the TIM-HF trial, there were no differences between groups in cardiovascular and all-cause mortality or in hospitalizations at a median follow-up of 26 months.

    “The TIM-HF trial69 randomly assigned 710 patients with an LVEF of ≤35%, NYHA class II–III and a history of HF decompensation within the previous 2 years to telemonitoring (weight, BP and heart rhythm data transmission) compared with usual care and found no differences between the groups in cardiovascular and all-cause mortality or in hospitalizations at a median follow-up of 26 months.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
