Challenges of Shared Decision-making by Clinicians and Patients With Low-risk Differentiated Thyroid Cancer

Importance Several international guidelines have endorsed more conservative treatment of low-risk differentiated thyroid cancer (LRDTC), yet patients are facing more treatment options with similar oncologic outcomes and are expressing feelings of confusion, dissatisfaction, and anxiety. Shared decision-making, which considers the patient’s values and preferences along with the most reliable medical evidence, has been proposed to optimize patient satisfaction in the context of the current clinical equipoise. Objectives To understand key individual and behavioral factors affecting the patient and clinician decision-making process in treatment decision for LRDTC. Evidence Review This systematic review and meta-ethnography involved a comprehensive literature search of MEDLINE, Embase, PubMed, and CINAHL databases for qualitative and mixed-method studies on patient and clinician experiences with the decision-making process for LRDTC treatment. The quality of the studies was assessed using the Mixed Methods Appraisal Tool; meta-ethnography was used for data analysis. Primary and secondary themes of the included studies were extracted, compared, and translated across articles to produce a lines-of-argument synthesis. Findings Of 1081 publications identified, 12 articles met the inclusion criteria. The qualitative synthesis produced 4 themes: (1) a bimodal distribution of patient preferences for treatment decisions; (2) clinician anxiety affected equipoise and biased their recommendations; (3) clinicians struggled to identify patient concerns and preferences; and (4) the clinician-patient relationship and psychosocial support were key to shared decision-making but were frequently overlooked. Conclusions and Relevance The findings of this systematic review and meta-ethnography emphasize the need for better patient-clinician communication, particularly with respect to eliciting patient concerns and preferences. With an ever-increasing pool of thyroid cancer survivors, future efforts should be directed at establishing and evaluating tools that will aid in shared decision-making for treatment of patients with LRDTC.
