About this trial
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.

Treatments tested in this trial
D-THIO (Deprescribing Thyroid Hormone In Older Adults)
BehavioralD-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.

Trial outcomes
Primary outcomes
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).
Secondary outcomes
Reduction of thyroid hormone overtreatment, measured as proportion of patients who had their TSH normalized.
Reduction in thyroid hormone overtreatment will be measured via EMR based on serum TSH in the normal range (=\>0.5-6 mIU/L). We will assess TSH as a continuous variable and as a categorical variable (\<0.5, 0.5-6, \>6 mIU/L) to also delineate unintended TSH above the upper limit of normal.
Provider-reported knowledge
Assessed via surveys by provider report and defined as the composite score obtained from 4 items with response categories ranging from low to high (5-point Likert scale; 1: low to 5: high); higher scores indicate increased knowledge.
Provider-reported intent to deprescribe
Assessed via surveys by provider report (single item) with response categories ranging from low to high (5-point Likert scale; 1: very unlikely to 5: very likely).
Provider-reported self-efficacy
Assessed via provider surveys using the 9-item validated deprescribing self-efficacy survey designed to gain a better understanding of how providers rate their self-efficacy in deprescribing medications in their older adult patients (scale 0-100; higher scores indicate higher self-efficacy).
