Assessment of cognitive impairment is a required component of the AWV. A total of 2,999,338 electronic health records of individuals 65 and older for evidence of the AWV and documented diagnosis of dementia of any type between 2011–2015 were reviewed. Overall, 3,859 records of completed AWV (.08%) were noted. Of those, Welcome to Medicare AWV (G0438) constituted on average 22.5% of all AWVs. The overall 5-year average dementia diagnosis rate was 0.51 ± 0.51% and demonstrated a gradual increase over time. The rates of dementia detection correlated significantly with the total number of visits (r=0.97, p=0.007) and with the number of AWVs (r=0.90, p=0.04). Despite a relative paucity of evidence on the performance of the AWV approach on improved dementia detection and subsequent care and several implementation barriers, the AWV provides the only sustainable and regular opportunity to establish a baseline measurement and identify changes in cognitive status over time.
