Brief summary

The overarching aim of the programme 'Stimulating evidence based, personalized and tailored information provision to improve decision making after oesophagogastric cancer diagnosis' (SOURCE) is to provide oesophagogastric cancer patients at all disease stages with evidence based and personalized information about survival, treatment-related side-effects and/or complications and health related quality of life, tailored to patients' specific information needs, to facilitate informed decision making about treatment and thereby optimize personal care and outcomes. For this purpose the Source tool and training were designed. The Source tool is a prediction model based website to be used by care givers for informing patients about the outcomes of treatment. The Source training for care givers is designed to learn care givers how to inform patients effectively, especially about the outcomes of treatment.

Detailed description

The overarching aim of the programme 'Stimulating evidence based, personalized and tailored information provision to improve decision making after oesophagogastric cancer diagnosis' (SOURCE) is to provide oesophagogastric cancer patients at all disease stages with evidence based and personalized information about survival, treatment-related side-effects and/or complications and health related quality of life, tailored to patients' specific information needs, to facilitate informed decision making about treatment and thereby optimize personal care and outcomes. For this purpose the Source tool and training were designed. The Source tool is a prediction model based website to be used by care givers for informing patients about the outcomes of treatment. The Source training for care givers is designed to learn care givers how to inform patients effectively, especially about the outcomes of treatment. The primary aim of the SOURCE trial is to investigate the effect of the tool and training on the (numerical) precision of information about outcomes of treatment in the treatment information consultation. Secondary outcomes include: patients' satisfaction, evaluation and knowledge of the information provided by the health care provider, evaluation of the decision made and health related quality of life. A pragmatic stepped wedge design will be used to test the effect of intervention. 21 health care providers will include 3 patients as control measurements (before intervention) and 3 patients as intervention measurements (after intervention). Participating centers will be divided into geographical subgroups, in which the transition period (in which the intervention will take place) will be spread across time. All oesophageal and gastric cancer patients scheduled for a treatment information consultation with a participating health care provider are suitable for inclusion and will be approached for participation in the SOURCE study. Measurements include audio recordings of the treatment information consultation and questionnaires filled in by patients and health care providers at different moments in time. Audio recordings will be scored and analyzed based on a study specific coding scheme. The investigators estimate the physical burden/risk of this study to be negligible.

Interventions

OTHERTool and training

The Source tool aims to assist health care providers with giving evidence based information about treatment outcomes by providing visualizations of personalized predictions of treatment outcomes for different treatments of oesophageal and gastric cancer. These predictions result from recently designed and updated prediction models on the survival, toxicity, complications and health related quality of life of oesophageal and gastric cancer patients. The training aims to teach participants to inform patients about outcomes of treatment. The training is placed in the context of shared decision making (SDM), following the 4-step model by Stiggelbout et al., 2015.8 The training is provided in small groups (3-6 participants) by an experienced trainer and supported by professional actors. The training aims to address knowledge, attitude and skills.
