Brief summary

Introduction Due to improvements in diagnostics and treatments, the 5-year survival for patients with breast cancer is 80-90% after initial diagnosis. During treatments, patients typically have consultations weekly and then gradually reduce to annual visits. During this transition from hospital-based care to health self-management, the breast cancer survivors are encouraged to e.g. exercise because of accumulating evidence for the efficacy of exercise training in cancer survivorship, and in the majority of cases, adhere to endocrine treatments to reduce the risk of breast cancer recurrence. Design and methods The study is a one-arm convergent parallel mixed-methods feasibility intervention study. The quantitative data will be the use of the Bone@bc app (intervention) and questionnaires (n=50) and the Qualitative data will be semi-structured interviews (n= 15 - 20)

Detailed description

AIM The aim is to investigate the feasibility and user satisfaction of an app Bone@BC version 3.0 and if the app Bone@BC can enhance self-efficacy and investigate user statistics and traffic in the app Bone@BC by using a convergent parallel Mixed-Methods design. Recruitment and procedure For the quantitative data, the recruitment will follow a consecutive sampling strategy, the follow-up group with the electronic patient-reported outcome (ePRO) and systematic consultations (n= 50) will be recruited from the Endocrinology Out-Clinic at Rigshospitalet, Denmark. For the qualitative data, the participants will be recruited from the group participating in the quantitative data following a nested sampling. The patients will be recruited by the principal investigator Trine Lund-Jacobsen (TLJ), or clinical physicians from the Department of Endocrinology, Rigshospitalet, Denmark. The identification of patients will be given to the principal investigator (TLJ) in case the patients are accepted to be contacted for further written and oral information about the project, letter for the subject's rights is handed out and then be provided for obtaining written consent from the patient. The patients who regret or refuse to give consent to participate in the study will be registered and we will note the reason why the patients refuse or regret participating in the study.

Design outcomes

Primary

MeasureTime frameDescription
The System Usability Scale (SUS)Week 12a self-administrated questionnaire with 10 items with five response options for respondents; from Strongly agree to Strongly disagree. A SUS score above a 68 would be considered above average and anything below 68 is below average.
Feasibility parameters as adherence, acceptability, response rate, representativeness, recruitment rate, and satisfactionWeek 12Semi-structured interviews
Bone@BC appFrom baseline and to week 12Patient-reported outcome(s) from the app on the questions provided daily on Health-Related Quality of Life, late side-effects, symptoms and concerns perspectives, and level of Physical Activity in the app Bone@BC). The daily questions will be from the Eortc Library and will be analysed in percentages.

Secondary

MeasureTime frameDescription
Changes in patient empowerment measured by The Health Education Impact Questionnaire.baseline (0 months) and week 12he Health Education Impact Questionnaire i a 42 items questionnaire with a 4 point response scale (strongly disagree, disagree, agree and strongly agree). Higher values in the Health Education Impact Questionnaire scales indicate better status, except for Emotional distress, where higher values indicate higher distress.
Changes in symptoms of depression and anxiety measured by Hospital Anxiety and Depression Scalebaseline (0 months) and week 12The Hospital Anxiety and Depression scale is a 14-item scale with seven items each for anxiety and depression subscales. Scoring for each item ranges from zero to three. A subscale score \>8 denotes anxiety or depression.
Changes in in app user measured by Open source web analytics application Matomo Analyticsweek 4, week 8 and week 12In-app user analytics will be collected to track user behavior such as the number of app sessions the user have measured by numbers (quantity). Length of app sessions measured by time (hours and sec.). Frequency of use measured in numbers (quantity). Data on when the app was first opened measured as the specific site. Geographic place measured as country. How many pages the users use measured as numbers (quantity). How long time the users spend on the pages measured as time (hours and sec.). Bounce rate measured as numbers (quantity). Returning for the first time measured as numbers (quantity).
Changes in Quality of life measured by the European Organization for Research and Treatment of Cancer Quality of Lifebaseline (0 months) and week 12Health-related quality of life scale. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.
Changes in self-efficacy measured by Self-efficacy for managing chronic disease 6-item scale (SES6G)Week 4, week 8 end week 12The Self-efficacy for managing chronic disease 6 item scale is a 6 item scale. Scoring for each item ranges from zero to ten. A high scale score represents a high self-efficacy.
