Exhibit 3. Trends in daily and semimonthly crude 30-day COVID-19 mortality rates, by cognitive and functional status, among residents of a sample of US nursing homes, 2020.

Exhibit 3

SOURCE Authors’ analysis of resident-level data from 282 nursing homes operated by a large, long-term care provider. NOTES Trend lines were estimated with locally weighted scatterplot smoothing, using all data points from the analytic sample (daily from March 16 through November 15). A scatterplot of unadjusted semimonthly mortality rates is superimposed. Cognitive Function Scale (CFS) scores range from 1 to 4; scores of 3 and 4 indicate advanced cognitive impairment. The Morris activities of daily living (ADL) score signifies the extent to which residents are dependent in seven activities of daily living, denoted by a higher score. An ADL score of 19 represents the seventy-fifth-percentile value of the analytic sample and reflects a substantial level of functional impairment.
