NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above).

Pay-it-forward to Promote HBV/HCV Testing among International Migrants from LMICs in China: Protocol for a Cluster Randomized Controlled Trial
ABSTRACT
Background:
Hepatitis B virus (HBV) and hepatitis C virus (HCV) are significant global health concerns, particularly prevalent in low- and middle-income countries (LMICs). In China, a significant number of international migrants from LMICs reside, many of whom are at high risk of HBV/HCV infection with few test utilization. Previous studies presented Pay-it-forward (PIF) strategy has proven effective in promoting sexually transmitted infections (STIs) test in various populations. This study aims to evaluate the effectiveness of a PIF intervention in promoting HBV/HCV testing among international migrants from LMICs in China.
Objective:
Aims to evaluate the impact of a pay-it-forward (PIF) intervention in promoting hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among international migrants from low- and middle-income countries (LMICs) residing in China.
Methods:
A two-arm cluster randomized controlled trial will be conducted in Guangzhou, China. Participants will be recruited from a public hospital serving a large migrant community. Eligible participants will be randomly assigned to either the PIF intervention arm or the control arm in a 1:1 ratio. Participants in the intervention arm will receive free HBV/HCV tests donated by previous participants and will have the opportunity to donate to support future tests. The control arm will receive standard medical services with self-paid testing. The primary outcome is the proportion of participants tested for both HBV and HCV. Data will be collected through a self-administered questionnaire and hospital records, and analyzed using generalized estimating equations to account for clustering effects.
Results:
The data collection has been completed, and the information of 100 participants was included to the data analysis.
Conclusions:
This study is innovative in targeting international migrants from LMICs in China and employing the PIF strategy to promote HBV/HCV testing. The PIF intervention is expected to increase testing rates by addressing financial barriers and fostering a sense of community support. The findings will contribute to the understanding of HBV/HCV testing promotion among this understudied population, with potential implications for public health policy and practice. Clinical Trial: ChiCTR2400082560. Registered on 1st April 2024.
