Outcome Measures

Primary Outcomes (1)

  • Decision Conflict Scale: DCS

    which assesses an individual's perception and understanding of decision-making by 16 items. The scale is 5-point Likert scale from 0 (Strongly Agree) to 4 (Strongly Disagree), and scores are calculated through a) summed, b) divided by 16, and c) multiplied by 25, and range from 0 (no decisional conflict) to 100 (extremely high decisional conflict).

    at enrollment

Secondary Outcomes (6)

  • Decision Regret Scale: DRS

    at 6month, 12month after enrollment

  • Shared Decision Making Questionnaire (SDM-Q-9)

    at enrollment, and 6month, 12month after enrollment

  • Patients' Perceived involvement of Care Scale (PICS)

    at enrollment, and 6month, 12month after enrollment

  • multifocal approach to sharing in shared decision making(Mappin'SDM)

    at enrollment, and 6month, 12month after enrollment

  • Comparison of Quality of Life between the shared decision group and standard care group

    at enrollment, and 6month, 12month after enrollment

  • +1 more secondary outcomes

Study Arms (2)

SDM Group (Shared Decision-Making Group; Intervention Group)

EXPERIMENTAL

* Patients will receive detailed information, including an information leaflet about treatment options. * Clinicians will guide patients through a structured SDM protocol before finalizing the treatment decision.

Other: SDM protocol

SC Group (Standard Care Group; Control Group)

NO INTERVENTION

\- Patients will receive standard medical care following current clinical practices without the SDM protocol.

Interventions

Card news and Videos related to general knowledge and treatment of low-risk thyroid cancer

SDM Group (Shared Decision-Making Group; Intervention Group)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults aged 18 years or older with a thyroid nodule of 1.0 cm or less confirmed as Bethesda category V (suspicious for PTC) or VI (PTC) based on cytopathological examination, or Bethesda category III (atypia of undetermined significance) with a confirmed BRAF V600E mutation.
  • Patients with no evidence of distant metastasis, cervical lymph node metastasis, recurrent laryngeal nerve invasion, or tracheal invasion. Additionally, no evidence of extrathyroidal extension (ETE) should be present, and the tumor must not belong to high-risk subtypes of PTC (e.g., diffuse sclerosing, columnar cell, or solid subtype).

You may not qualify if:

  • Patients who cannot undergo regular follow-up or are expected to have difficulties with follow-up.
  • Patients with indeterminate or benign findings on thyroid biopsy.
