Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Patients With Chronic Hepatitis C in Colombia (outCome)
Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Patients With Chronic Hepatitis C - An Observational Study in Colombia (outCome)
This is a prospective, multi-center observational study in adult participants chronically infected with hepatitis C virus (HCV) receiving the interferon-free ABBVIE REGIMEN (ombitasvir/paritaprevir/ritonavir with or without dasabuvir) with or without ribavirin (RBV). The prescription of a treatment regimen was at the discretion of the physician in accordance with local clinical practice and label.
This study focused on collecting real world data. Follow-up visits, treatment, procedures and diagnostic methods followed physicians' routine clinical practice using a 12-week treatment regimen (four visits plus two interim data collection windows) or a 24-week treatment regimen (four visits plus three interim data collection windows) and is based on the anticipated regular follow-up for patients undergoing treatment for chronic hepatitis C (CHC). Participants are observed for the duration of the ABBVIE REGIMEN therapy and for up to 24 weeks after treatment completion.

Description détaillée
This prospective, multi-center observational study in adult participants chronically infected with hepatitis C virus (HCV), receiving the interferon-free ABBVIE REGIMEN with or without RBV are offered the opportunity to participate in this study during a routine clinical visit at the participating sites at the discretion of the physician and is made independently from this observational study and preceded the decision to offer the participant the opportunity to participate in this study.
After written informed consent is obtained, demographics, HCV disease characteristics, co-morbidities, co-medication, treatment details, and laboratory assessments as recorded in the participant's medical records (source documentation) are documented in the electronic case report form (eCRF). Participants are observed for the duration of the ABBVIE REGIMEN therapy and for up to 24 weeks after treatment completion. No patient identifiable information was captured; a unique participant number was automatically allocated by the web based system once the investigator or designee created a new participant file.
This study focuses on collecting real world data. Follow-up visits, treatment, procedures and diagnostic methods follow physicians' routine clinical practice. The observational study period entailed the following data collection schemes:
- 12-week treatment regimen: four visits plus two interim data collection windows
- 24-week treatment regimen: four visits plus three interim data collection windows This schedule was based on the anticipated regular follow-up for patients undergoing treatment for CHC.

EuroQol 5 Dimension 5 Level (EQ-5D-5L) Questionnaire Index Score: Change From Baseline to EoT
Délai: EoT (up to 24 weeks)
|
The EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by participants.
The 5 items in the questionnaire comprise 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) each of which are rated on 5 levels of severity (1: indicating no problem, 2: indicating slight problems, 3: indicating moderate problems, 4: indicating severe problems, 5: indicating extreme problems), and a separate VAS.
The higher the score, the worse the quality of life.
For the VAS, the higher the score, the better the quality of life.
Participant responses to the EQ-5D-5L were used to generate a health status index (HSI).
HSI ranges is anchored at 0 (dead) and 1 (full health).
