^asingle test order record can be linked to multiple encounters, and thus multiple care settings. Therefore, the sum of tests by care setting will be greater than the sum of unique tests (“Total”). The care setting(s) recorded on the associated encounter(s) linked to each test record are reflected
^bExplorys has Telemedicine available as a separate care setting, whereas other EHR networks do not
^cAcademic Health System has the non-hospital clinic setting (“clinic”) available as a separate care setting, whereas other EHR networks combined that category with the hospital outpatient care setting
