Renal Cell Carcinoma Renal Cell Carcinoma Metastatic | Other: Decision aid |
Background: Treatment options for patients diagnosed with RCC depend on the stage of the disease, histopathology and patient's preferences and values regarding outcomes. For local (non-metastatic) disease, gold standard for treatment is surgical resection of the tumour. Besides this, ablative therapies or active surveillance could also be an option. For metastatic disease, targeted therapy and/or immunotherapy can be offered and new treatment options are being tested in clinical trials. The number of available treatment options for patients with RCC is increasing, but the availability of these options differs per hospital and the transparency about treatment options is limited, resulting in practice variation between hospitals.
Decision aids help patients to make decisions regarding treatment, particularly when there is not one medically superior treatment option. In this tools treatment options are explained, including outcome information such as possible side effects and benefits of therapy. Decision aids have proven to lead to increased patient knowledge, less anxiety in patients, improved health outcomes such as physical en mental health, reductions in unwarranted variation in care and costs, greater alignment of care with patients' values.
For patients with RCC, two decision aids are in development right now: one decision aid focussed on local disease and one decision aid focussed on metastatic disease. Using these decision aids, patients are encouraged to make a well-informed decision together with the healthcare professional.
Objective: To assess how the decision aids for RCC influence the quality of the decision-making processes for RCC, defined as the extent to which elements of shared decision-making (SDM) are observed.
Design, setting and participants: This study includes patients clinically diagnosed with RCC, facing a decision which is addressed in the decision aids. Study design will be a prospective multicenter pre-test post-test study.
Outcome measurements and statistical analysis: The primary endpoint of this study is the mean change in OPTION-5 score between pre-test and post-test groups. Secondary outcome measures include perceived quality of the decision-making process, quality of the decision and implementation of the decision aids.

Other: Decision aid
Online interactive decision aid for RCC |
- OPTION-5 [ Time Frame: During consultation ]Observed patient involvement in decision-making
- Decisional conflict scale [ Time Frame: Two weeks and nine weeks after consultation ]Validated scale to measure personal perceptions of uncertainty in choosing options, modifiable factors contributing to uncertainty and effective decision making.
- Preparation for decision-making [ Time Frame: Two weeks after consultation ]Validated scale that assesses the patient's perception of how useful a decision aid is in preparing the respondent to communicate with their practitioner at a consultation visit and making a health decision.
- Control preference scale [ Time Frame: Two weeks after consultation ]Validated measure of patient's preferred and actual roles in treatment decisions
- SDM-Q-9 [ Time Frame: Health care professional: directly after consultatiion, patient: two weeks after consultation ]Validated questionnaire of perceived level of shared decision-making
- Knowledge check [ Time Frame: Two weeks after consultation ]Objective assessment of patient's understanding of information relevant for the decision at stake using ten questions which can be answered as true/false/I don't know.
- Implementation of the decision aids [ Time Frame: Nine weeks after consultation ]Qualitative information about experiences with implementation and use of the decision aids will be obtained through semi-structured interviews with patients and healthcare professionals.
