Key result
ICDs are linked to ~0.4-point lower health certainty scores compared to pacemakers.
Why the study?
Does having an ICD compared to a pacemaker affect perceived health security in chronic illness among patients with cardiac devices?
Observational (n=176)
Yes
Does having an ICD compared to a pacemaker affect perceived health security in chronic illness among patients with cardiac devices?
A novel patient-reported outcome measure highlights that while certainty about health remains stable over time for device patients, those with ICDs feel less secure than pacemaker patients.
May warrant monitoring health perceptions in ICD patients; this Level 3 observation leaves open causality and needs prospective confirmation.
Scale measuring the construct of "health security in chronic illness" (HSCI) was piloted in Canadian cardiac device patients (N = 176) enrolled in a remote-monitoring study at 2 timepoints. Analysis revealed a 2-factor solution, labeled as "support" and "certainty". Patients reported receiving less support over time, but consistent health certainty. Patients with implantable cardioverter defibrillators felt less secure over time and reported lower levels of health security in chronic illness than pacemaker patients.

Force et al. (2023) conducted an observational in Cardiac implantable electronic devices (CIEDs) (n=176). Implantable cardioverter defibrillator (ICD) vs. Pacemaker (PM) was evaluated on Health certainty subscale of the Health Security in Chronic Illness (HSCI) measure (p=0.01). Patients with implantable cardioverter defibrillators reported significantly lower certainty regarding their health than pacemaker patients (mean score 3.41 vs 3.76, P=0.01).
