Abstract

Abstract : Background . Despite high efficacy rates for direct acting antiviral regimens to cure hepatitis C virus infection, many patients experience treatment-related symptoms. Accurate reporting of adverse events is mandatory to determine drug safety. Previous research in other medical conditions has documented discordance between clinician-reported and patient-reported symptomatic adverse events. Aims . To explore concordance and associated factors, between clinician-recorded and patient-reported fatigue, headache, and nausea/vomiting during a clinical trial of three treatment regimens. Methods . Data were collected between treatment start and 31 days posttreatment. Patients completed Patient-Reported Outcomes Measurement Information System measures of fatigue and nausea/vomiting and the Headache Impact Test. Clinician-recorded data were abstracted from medical records. Concordance was evaluated by weighted kappa. Demographic and clinical factors associated with concordance were identified using logistic regression models. Results . Participants included 1, 058 patients treated for chronic hepatitis C (average 54.9 years; 43% Black; 59% male). Weighted kappa estimates and 95% confidence intervals between patients (no/mild vs. moderate/severe symptoms) and clinicians (not present vs. present) were fatigue (k = 0.09, 0.02-0.16), headache (k = 0.08, 0.02-0.14), and nausea/vomiting (k = 0.20, 0.11-0.28). Older age and having private insurance (compared to Medicaid) were associated with better headache concordance. Older age, male, absence of psychiatric condition, and ≤2 comorbidities were associated with better nausea/vomiting concordance. Conclusions . Poor concordance was observed between patient-reported and clinician-recorded symptomatic adverse events. Despite study limitations, previous literature in other conditions support these findings. Integrating patient-reported data to inform adverse event reporting would improve evaluations of treatment safety (http://CT.gov/ Registration: NCT02786537 ).
