Receipt of composite quality measure within 30 days between participants with pre-existing MCI and cognitively normal patients

Number of 4 procedures within composite quality measure received	Participants with Pre-existing Normal Cognition (n=432)	Participants with Pre-existing MCI (n=159)	P-value	Unadjusted cumulative odds ratios (95% CI) for MCI vs normal cognition	Adjusted cumulative odds ratios (95% CI) for MCI vs normal cognition

Abbreviations: MCI, mild cognitive impairment.

The primary outcome was a composite quality measure representing the number of 4 procedures (carotid imaging, cardiac monitoring, echocardiogram, and rehabilitation assessment) received within 30 days after AIS (ordinal scale with values of 0, 1, 2, 3–4).

We combined the 2 categories corresponding to receiving 3 and 4 of the 4 procedures because only one individual received all 4 procedures resulting in a 4-level composite quality measure (values of 0, 1, 2, 3–4). Ordinal logistic regression models estimated the cumulative odds of receiving the composite quality measure (primary outcome) before and after adjusting for patient factors (age, sex, race/ethnicity, education, net wealth, income, Charlson comorbidity index score, depressive symptoms, functional limitations in basic and instrumental activities of daily living, marital status/living arrangement, geographic proximity to adult children, and having an adult daughter) and hospital factors (medical school affiliate or teaching hospital, region, bed size, and authority type).
