Overview
Brief Summary
Adherence to antiviral treatment in chronic hepatitis C (CHC) is an important factor to achieve sustained virological response (SVR). The aim of our study is to evaluate the efficacy of a multidisciplinary support program (MSP) in adherence to and efficacy of pegylated interferon alfa-2a and ribavirin compared to the conventional approach. We assessed 447 patients with CHC receiving antiviral treatment distributed into 3 groups: control group (recruited 2002-2004, n= 147), MSP-pilot group (recruited 2005-2006, n=131), and MSP-validation group (recruited 2007-2009, n=169).
Detailed Description
Adherence to antiviral treatment in chronic hepatitis C (CHC) is an important factor to achieve sustained virological response (SVR). The aim of our study is to evaluate the efficacy of a multidisciplinary support program (MSP) in adherence to and efficacy of pegylated interferon alfa-2a and ribavirin compared to the conventional approach. We assessed 447 patients with CHC receiving antiviral treatment distributed into 3 groups: control group (follow-up 2002-2004, n= 147), MSP-pilot group (follow-up 2005-2006, n=131), and MSP-validation group (follow-up 2007-2009, n=169).A cost-effectiveness analysis was performed using a Markov model.

Outcomes
Primary Outcomes
Adherence to Treatment
Time Frame: 48 months
Adherent patients were defined as those receiving equal or more than 80% of total dose of pegylated interferon (180 microg/week) and ribavirin (1200 mg/d) during equal o more than 80% of duration treatment (48 weeks). Non-adherent patients were defined as those receiving less than 80% of total dose of pegylated interferon (180 microg/week) and ribavirin (1200 mg/d) during less than 80% of duration treatment (48 weeks).
Secondary Outcomes
- Efficacy of Treatment Measured by Sustained Virological Response(baseline and 72 weeks)
