Assessment of urine colour using a wallet card: a randomised study of a novel patient self-care tool during chemoradiation for oesophageal cancer.

Background: Patients undergoing neoadjuvant chemoradiation for oesophageal cancer often experience dehydration from decreased fluid intake and increased losses. Despite frequent clinical visits during treatment, patients can still present with dehydration, suggesting the need for increased patient awareness and engagement around adverse event management at home. Evidence for benefits of self-monitoring may help motivate patients to engage proactively in their own care to improve their treatment experience.
