Feasibility Testing of the Alert for AFib Intervention.

The study was a feasibility pilot and was not powered to show whether the intervention improved knowledge, attitudes, beliefs, or clinical outcomes. It was done at one academic medical center in the Midwest, and participants were recruited from patients who had already agreed to have their records reviewed for research. The response rate to invitations was 15%, and the sample was 96% White and 54% held a 4-year college degree or graduate degree, so results may not apply to other older adults. The KABAFS was newly developed, had content validity testing, but had not been tested for construct validity when participants completed it. Control participants reported seeking information about AF from the Internet or their health care provider after enrollment, which could have affected their scores. The paper reports different analyzed counts for KABAFS outcomes: text says 37 intervention and 38 control had complete data, while the KABAFS comparison table says 38 intervention and 38 control.

The authors declared no potential conflicts of interest. The research was supported by the National Institute of Nursing Research of the National Institutes of Health under Award Number K23NR0114253.

Do not read this pilot as proof that daily pulse checks detect AF early or prevent stroke. It tested feasibility, not treatment effects. The intervention bundled education, video, risk calculator, pulse instruction, logging, and follow-up, and the contribution of any single component cannot be separated.
