NCT06629272

Brief Summary

The proposed study focuses on testing a novel adapted evidence-based multilevel intervention, Deprescribing Thyroid Hormone In Older Adults (D-THIO), to support thyroid hormone deprescribing (dose de-escalation and/or discontinuation) in older adults with thyroid hormone overtreatment and/or misuse and reduce patient harm. Findings from this study will lay the groundwork for broad implementation of D-THIO and serve as a model for deprescribing inappropriate medications for other endocrine conditions and conditions with biochemical monitoring.

Outcome Measures

Primary Outcomes (1)

  • Thyroid hormone deprescribing by providers

    Assessed by proportion of patients who had any thyroid hormone dose de-escalation and/or thyroid hormone discontinuation. Thyroid hormone deprescribing is defined as thyroid hormone dose de-escalation and/or discontinuation and will be assessed via Electronic Medical Record (EMR).

    6 months post-enrollment

Secondary Outcomes (8)

  • Reduction of thyroid hormone overtreatment, measured as proportion of patients who had their TSH normalized.

    6 months post-enrollment

  • Provider-reported knowledge

    6-12 months post-enrollment

  • Provider-reported intent to deprescribe

    6-12 months post-enrollment

  • Provider-reported self-efficacy

    6-12 months post-enrollment

  • Patient-reported discussion of deprescribing with provider

    3-6 months post-enrollment

  • +3 more secondary outcomes

Study Arms (2)

D-THIO (Deprescribing Thyroid Hormone In Older Adults)

EXPERIMENTAL

D-THIO is an innovative adapted multilevel intervention. Providers in the intervention arm will receive: 1) an introductory letter, and 2) the D-THIO pharmaceutical opinion via EMR-compatible correspondence. After randomization of their treating providers, patients in the intervention arm will receive a study packet including: 1) introductory letter, and 2) the D-THIO patient brochure (educational EMPOWER brochure).

Behavioral: D-THIO (Deprescribing Thyroid Hormone In Older Adults)

Enhanced usual care

ACTIVE COMPARATOR

This arm will receive enhanced usual care. Providers in the control arm will receive: 1) an introductory letter signed by the PI and site-PIs, and 2) the ATA hypothyroidism pocket card via EMR. Patients in the control arm will receive a study packet including: 1) introductory letter, and 2) the ATA patient brochure.

Behavioral: Enhanced usual care

Interventions

D-THIO consists of evidence-based pharmaceutical opinion letters to providers advising deprescribing for their patients 65 years and older with thyroid hormone overtreatment/misuse and EMPOWER ("Eliminating Medications through Patient Ownership of End Results") brochures to their patients.

Masking Details
Because the intervention is educational in nature, blinding is not possible. But, to preserve a certain level of blinding and protect against bias, the study will be presented as a "medication optimization study" and consenting patient participants will be informed that their medication profiles will be transmitted to the research team within the following months and that they will receive a customized brochure at some point during the next year that may contain recommendations for change which they can discuss with their prescribing provider. For providers, blinding will be achieved by presenting the same study timeline. Providers will be aware that they will receive a customized letter with thyroid hormone optimization recommendations and that their patients will receive an intervention at some point during the following year, and remain blinded to group allocation throughout the course of the study.
