Evaluation of a County-Based Eye Health Service Model in Rural Chinese Children
China20,000 participantsStarted 2025-01-01
Plain-language summary
This project proposes to conduct a prospective, multicenter registry study in rural China to evaluate, under real-world conditions, the implementation effectiveness of an integrated child eye health service model centered at the county level and coordinated across county, township, village, and school tiers. The target population will include all children and adolescents within participating counties, and the primary exposure will be the annual coverage and implementation intensity of this service model. The study will focus on its impact on clinical outcomes such as refractive error correction rates and referral rates following eye disease screening, while also examining annual trends in disparities in access to different eye care services. Through long-term and systematic observation, the project aims to clarify the sustained effects of this eye health service model on improving the management of pediatric eye diseases, enhancing visual function, and promoting health equity, thereby providing evidence-based support for optimizing the rural child eye care system in China.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
