ROC line call defined as having at least 1 call at any time during the campaign April 21, 2020–May 12, 2020. Analytic Sample represents a subset of the campaign population defined as those meeting the exclusion criteria including those without Healthcare System contact (ROC call, health care appointment, or COVID-19 test) prior to the start of the campaign. At Risk defined as patients one or more moderate comorbidities for COVID-19 including elderly (65 years-old or more) or adults (18 years-old or more) with one or more of the following comorbidities: severe obesity, diabetes, chronic obstructive pulmonary disease /emphysema, asthma, hypertension, coronary artery disease, congestive heart failure, lupus, sarcoidosis, immunodeficiency; and excluding: patients currently on dialysis, had a history of a left ventricular assist device procedure, were active or recent transplant patients, or have malignancy, HIV/AIDs, or sickle cell disease
