Informal Caregiving in Patients With Atrial Fibrillation and Multimorbidity: A Cross-European Study of Caregiver Burden, Health-Related Quality of Life, and Caregiver Engagement.

The survey compared groups at one time point, so it cannot show that higher engagement causes less burden or that support changes outcomes. Caregivers were recruited by convenience through an association website and hospital contacts, and had to use an online platform, so it may miss caregivers with less access or more severe strain. All outcomes were self-reported by caregivers, so burden, mood, and quality of life may be influenced by current distress or social expectations. The sample was 179 caregivers from Italy, Romania, and Spain, mostly White and female, so findings may not apply to other countries, ethnic groups, or male caregivers. The paper did not measure patient outcomes or nurse-delivered care, so it cannot tell you how caregiver burden affects the patient or whether a nursing intervention helps. The authors noted that variations in healthcare access, socioeconomic status, disease severity, and social support were not exhaustively controlled.

The study was funded by the European Union's Horizon 2020 Research and Innovation Program under grant agreement 899871. Authors declared research grants from EU Horizon programs, including grant agreement 899871 and Horizon 2022 grant agreement 101095470; one author reported investigator-initiated quality improvement grants from Bristol-Myers Squibb and Pfizer paid to the institution and involvement in EU-funded atrial fibrillation and multimorbidity projects; one author reported research grants from Chiesi, Alexion, Lundbeck, and Sanofi and speaking engagements for Sanofi, Roche Diabetes Care, and Merck Serono outside the submitted work; one author reported no conflicts of interest.

Do not conclude that raising caregiver engagement will reduce burden. The study was cross-sectional, observed only associations at one time point, and did not test any intervention.
