Summary

This trial tests whether offering small gift cards can motivate living kidney donors to complete required follow-up visits at 6 months, 1 year, and 2 years after donation. Half of the participants receive a gift card after finishing each checkup, while the other half follows the usual process without any incentive. The goal is to see if a simple reward improves compliance with national reporting standards and helps protect donor health.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
financial incentive (gift cards) for completing follow-up activities
What this could lead to
If it works, this approach could improve long-term health monitoring for living kidney donors, helping ensure they receive necessary follow-up care.
What could go wrong
This is a small, single-center trial, and the effect of small gift cards may not be large enough to change behavior or apply to other hospitals.
