Bolded text signifies statistically significant P-values (P < .05).

^aAdjusted for all covariates of interest: age, gender, vital signs (pulse oximetry, temperature, pulse, respiratory rate, systolic blood pressure), comorbidities (heart disease, diabetes, chronic lung disease, asthma), and other risk factors (question 1-5).

^bComorbidities were derived from patient problem list. Low-risk patients who did not report comorbidities in the risk assessment questionnaire may have had comorbidities documented in the problem list.

^cHeart disease ICD-10 codes I20-I25 or I30-I52 in problem list.

^dDiabetes ICD-10 codes E10-E14 in problem list.
