Why the study?
Does extraction of diagnoses from health care registers improve the sensitivity of identifying atrial fibrillation compared to questionnaires alone?
Does extraction of diagnoses from health care registers improve the sensitivity of identifying atrial fibrillation compared to questionnaires alone?
Extraction of diagnoses from health care registers substantially enhances the sensitivity of identifying atrial fibrillation compared to questionnaires alone, and should be applied for incidence and prevalence estimates.
Register extraction substantially boosts AF identification sensitivity over questionnaires alone; leaves open optimal methods for incidence estimates.
Use of questionnaires alone to identify cases of AF has low sensitivity. Extraction of diagnoses from health care registers enhances the sensitivity substantially and should be applied when estimates of incidence and prevalence of AF are studied.
