Patient Category	Definition	Exclusion criteria

Ever HCV screened	Any unique inpatient with HCV screened field answer “yes” and a result (positive or negative) entered in the HCV result field. For patients with hospital admissions in the evaluation period, if they had a valid screening result during at least one admission they were counted in the ever HCV screened group.	Any entry with no response in the HCV screening field. Entries with an HCV screened answer “yes” but without a result entered in the HCV result field.

Anti-HCV positive	Affirmative HCV screening field and a positive anti-HCV result. A patient with at least one valid anti-HCV positive result during the evaluation period was defined as anti-HCV Positive
Not anti-HCV positive	Affirmative HCV screening field and negative anti-HCV results on each screening (if screened multiple times, all results negative).
Linked to care	Any anti-HCV positive patient who had a documented HCV RNA or HCV core antigen test to confirm active infection after the date of hospital discharge, but on or before January 31, 2018.	Patients with documented HCV RNA or core antigen test results in the HCV treatment database dated before the discharge date for the hospital admission in which they screened positive.
Not linked to care	Any anti-HCV positive patient who did not have a test for active HCV infection at one of the HCV testing provider sites within the period between hospital discharge and January 31, 2018.	Patients with documented death date within the evaluation period.
