Because participants could be involved in more than one crash during the study period, the table presents results at the person-crash level. Among 99,950 unique participants, 52.3% were Female, 84.6% were Non-Hispanic White, 6.2% were Non-Hispanic Black, 4.2% were Hispanic, 3.2% were Asian/Pacific Islander, and 1.7% were Unknown/Other race/ethnicity.
Person-crashes were considered to have a condition if the first occurrence of the condition was documented in the Medicare Beneficiary Summary File Chronic Conditions Warehouse on or before the crash date.
Ranges from −2 to 26, where higher scores indicate greater multimorbidity. Based on International Classification of Diseases codes documented on MedPAR, skilled nursing facility, and outpatient claims in the 12 months prior to (and inclusive of) the crash date.
Within 8 days includes the day of the crash plus 7 days beyond that.
