Investigators used in-house-designed radiotherapy red and green light markers to distinguish individual measures after the provision of the initial nursing care to participants, added a homemade health education leaflet to collect data via actual observation, and counted the disappearance or fading of participants' body markers

From January 1, 2023 to June 30, 2023, a total of 200 participants were enrolled and undergoing radiation therapy. Inclusion Criteria: clear consciousness who could understand and comprehend Mandarin Chinese. Exclusion Criteria: patients with impaired consciousness or decreased cognitive abilities.

Investigators proposed a set of strategic initiatives :

1. Consistent Schedule for the Replacement of Positioning Line Pens: Consistent Schedule for the Replacement of Positioning Line Pens: Investigators recommend implementing a standardized replacement schedule for positioning line pens, with replacement performed after every 50 uses.
2. Tailored Educational Content: Investigators created personalized educational content tailored to each patient's educational background. This approach ensures that participants can easily understand their treatment plan.
3. Hypoallergenic Adhesive Patches: Investigators offered a variety of hypoallergenic adhesive patches, catering to the skin characteristics of individual participants.
4. Enriched Treatment Care Platform: Investigators commitment extended to creating a comprehensive treatment care platform, which provided guidance on positioning line usage, interactive community features, and practical information.
5. Participants with BMI > 25 and an education level of high school or below, without specific caregivers, were identified by placing a red dot on the treatment record and on the patient's happiness card. Patients with BMI < 25 and an education level of high school or above, with specific caregivers, were identified by placing a green dot on their records.
6. After implementing the red-green light differentiation for radiation therapy and individual interventions, educational pamphlets prepared in-house were added, to assess the maintenance status of the positioning marks.

The number of times the surface marks disappeared or faded during treatment was recorded on the day the participants completed treatment.
