HCV patients were comparable to propensity-score matched controls on all demographic and health history variables except comorbidity burden (Charlson Comorbidity Index), which was marginally greater in the HCV group (see Tables 2 and 3).




HCV patients also reported significantly more healthcare provider visits in the past six months (14.80 vs. 9.74, p<.05).
Because of the imbalance in comorbidity burden, additional analyses were rerun controlling for CCI. The results remained generally consistent:
- HCV patients reported significantly lower levels of MCS (Adjusted means = 46.77 vs. 48.63), general health (Adjusted means = 44.35 vs. 48.43), and mental health (Adjusted means = 66.65 vs. 71.26) (all p<.05).
- Bodily pain differences were no longer significant.
- HCV patients reported marginally higher absenteeism (Adjusted means = 8.35% vs. 3.74%, p=.06) and marginally higher presenteeism (Adjusted means = 20.01% vs. 14.96%, p = .09) than matched controls.
-- However, HCV patients did report significantly higher overall work impairment (Adjusted means = 25.43% vs. 16.35%,), emergency room visits (Adjusted means = 0.61 vs. 0.18), and physician visits (Adjusted means = 14.56 vs. 9.87) than matched controls (all p<.05). No differences were observed on activity impairment or hospitalizations.
