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:

  • David Gladstone, Sunnybrook Hopsital
  • Noah Ivers, Women’s College Hospital
