Inclusion Criteria:
- HCV viral load
- HCV genotype
- HCV qualitative
- HCV antibody
- HCV drug
- Continuously enrolled 12 months
Exclusion Criteria:
- Each outcome will be analyzed separately as time to first event, thus people who experience an outcome prior to their study start date are ineligible for analyses related to that particular outcome.
The results will be examined for sensitivity to the following possible exclusion criteria:
- Achieved SVR-12 prior to index date
- HCV treatment experienced prior to index date
- No visit in GI, Infectious Disease, or Liver Transplant / Hepatology
- No positive HCV test (genotype, viral load, or qualitative)

Direct Acting Antivirals

|
The time period during which a patient is dispensed the medication and for up to 180 days after initiation of the medication.

|
Comparison

Incidence of HBV Reactivation
Zeitfenster: Labs will be for up to 180 days following the initiation of a DAA.
|
We identified HBV reactivations in three different ways [Di Bisceglie et al., 2015; Yanny et al., 2018]: (1) patients who had a history of Hepatitis B core antibody (HBcAb) positive and were Hepatitis B surface antigen (HBsAg) negative at the time of initiating DAA therapy who became HBsAg positive within 180 days after receiving a DAA; (2) patients with undetectable levels of HBV DNA at the time of initiating DAA therapy who had a numerical result within 180 days after receiving a DAA; (3) patients with a numerical HBV DNA result at the time of initiating DAA therapy whose viral load increased by a factor of 10 within 180 days after receiving a DAA.
For all methods of detecting a reactivation, we required that the reactivations be clinically significant: bilirubin at least 3, aspartate aminotransferase (AST) at least 400, or alanine aminotransferase (ALT) at least 500.
|
Labs will be for up to 180 days following the initiation of a DAA.
