Summary

Most patients with non-medullary thyroid carcinoma (TC) achieve remission after primary treatment. Nonetheless, 30% develop recurrent disease and/or distant metastases resulting in worse survival. Patients with low- and intermediate-risk, whilst having a good prognosis, generally undergo similar primary treatment as those with a high-risk disease and face the risk of complications and burden of treatment, without a proven benefit in long-term outcome. For these patients, current guidelines state that less aggressive treatment (e.g. hemi-thyroidectomy vs. total thyroidectomy, and selective use of radioiodine (RAI) therapy), and tailored follow-up can be equally acceptable leaving room for patients' preferences. For high- risk patients, important unanswered question regard the optimal timing of starting tyrosine kinase inhibitors (TKI). For those who are asymptomatic or only mildly symptomatic, starting the treatment too early may expose them to side effects and impair quality of life, without evidence of a survival benefit. Different patients have different views on these decisions, and so do physicians. Therefore, care should honour preferences and values of individual patients, and care should involve patients through shared decision making (SDM). The principle of SDM is twofold: 1. physicians provide patients with information on the existing options, and 2. help patients identify their preferences considering their individual values and needs. This involves important life values, for instance the desire to do everything possible, or to minimise complaints. Addressing patients' treatment-related values is arguably the most difficult part of SDM so patient values are less likely to be discussed and honoured in a consultation. Current tools improve values deliberation but their effects are clearly insufficient. Tools should be integrated and applied in consultations to increase effectiveness. To strengthen values deliberation with TC as an example, a multifaceted intervention, COMBO, is proposed including 1) a patient values clarification exercise, named SDM-booster, 2) a physician values deliberation training using the SDM-booster, and 3) a patient decision aid. The SDM-booster strengthens values deliberation by 1) strengthening and clarifying patients' values and preferences, 2) communicating patients' values in the consultation, 3) serving as a focus in the values deliberation training.

Type	Name	Description
OTHER	Decision aid and SDM booster	The investigators develop the decision aid and SDM booster. The scope of the investigators of decision making combines the clinical and patient perspective. The decision aids are developed for patients with TC either newly diagnosed or patients with advanced disease, presently in the follow-up at the participating centers, covering the whole treatment trajectory of these patients (Figure 4). Three treatment decisions are considered: 1) the extent of thyroid resection, 2) the use of RAI, and 3) the initiation of TKIs.The SDM-booster is developed alongside the decision aids, as the SDM-booster (or values clarification exercise) is often a component developed together with a decision aid. The SDM-booster aims to shape patients' values regarding aspects of the decision and ensuing treatment preferences.
OTHER	Deliberation training	The investigators develop the deliberation training. It makes physicians more aware and responsive to patients' values. The communication training for physicians will consist of 1) an e-learning SDM-training lasting 40 minutes and, 2) an individual values deliberation training lasting 2 hours.
