Key result
Standardized training achieves ~23.5 hours of daily wearable cardioverter defibrillator wear time.
Why the study?
The study was designed to assess patient adherence to wearable cardioverter defibrillators as an indicator of device effectiveness, noting that patient training is not widely properly standardized.
Does standardized patient training improve patient adherence to wearable cardioverter defibrillators in patients at high risk of sudden cardiac death?
Observational (n=25)
No

Structured patient education for wearable cardioverter defibrillators achieves high device adherence, enabling safe monitoring while 76% of high-risk patients avoid permanent ICD implantation after recovery.
The study was designed to assess patient adherence to wearable cardioverter defibrillator as an indicator of device effectiveness. The patient training is not widely properly standardized. We enrolled 25 patients with a wearable cardioverter defibrillator to prevent sudden cardiac death between June 2020 and August 2022. Among them, 84% were male with a median age of 63.6 years. The indication was an ischemic (44%) and a non-ischemic (56%) disease. The patients were followed-up until the decision to upgrade to an implantable device was taken. We trained the patients according to our suggested protocol. The median wear time was 90 days, and the median daily wear time was 23.5 h, similar throughout sex, age, and indication groups. In total, 24% of the participants underwent cardioverter defibrillator implantation. Between the device-implanted and non-implanted groups, left ventricular ejection fraction and left ventricular indexed end-diastolic volume were significantly different (EF 35.8 ± 12 vs. 46.4 ± 8.5%, p = 0.028, iEDV 108 ± 52 vs. 70.7 ± 21.1 mL/m2, p = 0.024). We did not find any differences in cardiac magnetic resonance data, even though all patients who underwent device implantation had late gadolinium enhancement spots. Our results support standardized patient training to obtain great patient adherence to the instructions to the wearable device and therefore its effectiveness.

Fazzini et al. (2023) conducted an observational in High risk for sudden cardiac death (SCD) (n=25). Wearable cardioverter defibrillator (WCD) with standardized patient training protocol was evaluated on Patient adherence (median daily wear time). Standardized patient training for the wearable cardioverter defibrillator resulted in a high median daily wear time of 23.5 hours, and patients requiring subsequent device implantation had significantly lower left ventricular ejection fraction (35.8% vs 46.4%, p=0.028).
