Study Overview
Brief Summary
To examine the effect of a preparatory digital tool including a new instruction for deep inspiration breath hold (DIBH), before start of radiation therapy in women diagnosed with left sided breast cancer, compared with usual care.
Detailed Description
The following questions will be posted:
- Are there any differences in levels of distress (primary outcome) between the control and intervention group at baseline and over time?
- Are there any differences in preparedness for RT (secondary outcomes) between the control and intervention group at baseline and over time?
- Are there any correlations between Health Literacy (HL) levels (secondary outcome) and levels of distress (primary outcome) in the control and intervention group?
- Are there any differences in objective clinical variables (chest mobility and respiratory movements and planned absorbed dose to the heart) between the control and intervention group before and after the intervention (baseline and at planning CT)?
- Which patterns of practice and use of the application (when, how, how often and for how long) can be discerned from the intervention group?
- Are there any correlations between different levels of practice and use of the digital tool and primary and secondary outcomes?
- How do patients in the different groups (control and intervention group) describe their experience of care and information process during RT with DIBH?
- Are there differences regarding health economic variables in terms of costs and health care usage (e.g., estimated time for planning and conducting computed tomography (CT), number of scheduled CT examinations) and patient effects (e.g. co-morbidities (heart related), sick leave, and quality-adjusted life year (QALYs) between patients in control- or interventions group?
- Are there any differences regarding effects on environmental aspects and costs in the different groups (control and intervention)?

Arms & Interventions
A=Control group who receives customary information prior to RT with DIBH.
Usual care and information before start of radiotherapy with DIBH.
B=Intervention group usual care and the DIBH-App to practice at-home before RT with DIBH.
Usual care and information and a mobile application with breathing instructions and a sensor to attach around the chest. To be able to train at home before radiotherapy with DIBH starts.
Intervention: mobile application with breathing instructions and a sensor to attach around the chest. To be able to train at home before radiotherapy with DIBH starts. (Other)
Outcomes
Primary Outcomes
Distress (DIS-A)
Time Frame: time 5, 5 years after RT
The Distress Thermometer (DT) was developed as a simple tool to effectively screen for symptoms of distress. The instrument is a self-reported tool using a 0-to-10 rating scale, where 0 is no distress and 10 the worst distress.
Distress (DIS-A)
Time Frame: Time 1, baseline at randomisation/inclusion
The Distress Thermometer (DT) was developed as a simple tool to effectively screen for symptoms of distress. The instrument is a self-reported tool using a 0-to-10 rating scale, where 0 is no distress and 10 the worst distress.
Distress (DIS-A)
Time Frame: time 2, at CT-planning visit one week
The Distress Thermometer (DT) was developed as a simple tool to effectively screen for symptoms of distress. The instrument is a self-reported tool using a 0-to-10 rating scale, where 0 is no distress and 10 the worst distress.
Distress (DIS-A)
Time Frame: time 3, 3 weeks post RT
The Distress Thermometer (DT) was developed as a simple tool to effectively screen for symptoms of distress. The instrument is a self-reported tool using a 0-to-10 rating scale, where 0 is no distress and 10 the worst distress.
Distress (DIS-A)
Time Frame: time 4, 6 month post RT
The Distress Thermometer (DT) was developed as a simple tool to effectively screen for symptoms of distress. The instrument is a self-reported tool using a 0-to-10 rating scale, where 0 is no distress and 10 the worst distress.
Secondary Outcomes
- HRQoL and Health economic (EQ-5D-5L)(5 years post RT)
- e-HL (eHLQ)(at baseline when inclusion/randomisation)
- Communicative, critical and functional HL(at baseline when inclusion/randomisation)
- Preparedness(PCSQ-24)(at CT planning visit, one week)
- The Radiotherapy Experience Questionnaire, Swedish modified version(3 weeks post RT)
- HRQoL and Health economic (EQ-5D-5L)(at baseline when inclusion/randomisation)
