Abstract CN10
Background
Deep Inspiration Breath Hold (DIBH) technology is increasingly used with radiation therapy to protect healthy organs from unwanted absorbed dose. Using deep breaths, this technique creates as larger distance between the heart and the chest wall. DIBH has shown good results, but requires a well-prepared, involved patient who has learned the correct breathing technique so that optimal position and breathing patterns can be reproduced during each treatment session. There is no evidence regarding which type of inhalation is optimal or how to best train this. However, a person-centered model for DIBH training has been developed in co-design with relevant stakeholders, and this will be integrated into a digital information and instruction tool enabling training undertaken at home. The purpose of this project is to describe and evaluate a person-centered model to train the most optimal breathing technique for breath-adapted postoperative radiotherapy of women affected by left-sided breast cancer.
Methods
Using qualitative and quantitative methods, the project will examine how the model affects health-related outcome measures such as perceived health literacy (HL), distress (worry, anxiety) and the feeling of being prepared. It will also determine whether this training may be time and cost effective for the health service.
Results
A pre-study has shown optimal breathing technique and developed a coaching method. The digital tool is under development in a co-design process. A three-armed RTC will start during 2023.
Conclusions
This study will gain knowledge about what benefits individuals and the healthcare system may gain by using the model and the digital tool. An evidence-based methodology of breathing techniques and coaching methods can be standardized in the clinic and will contribute to equal, quality-assured, and cost-effective care and reduce the risk of future ischemic heart disease, which can lead to reduced quality of life and premature death.
