The objective of the PIAAF Family Practice study was to finnd Atrial Fibrillation (AF) among patients 65 years of age or older, a family practice based screening program that will be implemented using three simple methods– manual pulse check, single lead handheld ECG and blood pressure machine with automated AF detection algorithms.

Primary outcomes:

Sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of each screening test in the Family Practice setting.

Secondary outcomes:

Cost effectiveness of screening, OAC prescription rates, risk factors, and user feedback from the screening tools.

Co-Principal Investigators, with Jeff Healey of PHRI, were:
