Long-term compliance with regular surveillance is important for the prevention and timely management of chronic hepatitis B (CHB). However, there are no researches focusing on the compliance of hepatitis B virus infected patients in regular surveillance so far. The purpose of our study was to investigate the outpatient compliance with long-term regular surveillance in China. Data of 3257 CHB outpatients was pooled and analyzed to assess the outpatient's compliance with the long-term regular surveillance plan. In all outpatients, the non-follow-up and the follow-up group accounted for 73.2% and 26.8%, respectively. Among the follow-up outpatient's, only 48.9% received ongoing-follow-up and 51.1% were finally lost to follow-up; the median length of visiting duration was 25 months; and the predictive 1-, 2-, 3-, 4and 5-year ongoing follow-up rate was 72.7%, 52.5%, 42.4%, 33.8%, and 26.3%, respectively. In conclusion, our survey proved that the regular long-term surveillance on Chinese chronic HBV carrier is difficult to be fully implemented. A large proportion of outpatients do not receive routine follow-up and are at risk of treatment delay due to various social reasons.
