Proportion of unique outpatients seen in various settings with a primary diagnosis of AD or MCI who were African American. Left, The African American proportion of outpatients seen for AD within the Memory Disorders specialty clinic or in other Neurology clinics was less than the proportion seen for AD outpatients across the entire medical system (red line, 22.5%; p < 0.0001 and p = 0.0081 respectively) while the proportion seen within the Primary Medicine and Geriatrics clinics was greater than expected (both p < 0.0001). Right, A similar pattern held for outpatients seen for MCI, with African Americans also underrepresented in the Memory Disorders and other Neurology clinics (p = 0.0007 and p = 0.0036 respectively) and overrepresented in the Primary Medicine clinic (p < 0.0001) with a trend towards overrepresentation in the Geriatrics clinic (p = 0.029), relative to enterprise-wide average (blue line, 19.3%).
