Improvement of Free T4 in Newly Diagnosed Graves Disease Patients Through a Multifaceted Quality Improvement Approach.

INTRODUCTION

Graves disease (GD) is the most common cause of pediatric hyperthyroidism, and if untreated, may result in multisystem complications and decreased quality of life. Through a multifaceted quality improvement (QI) approach, we aimed to address treatment barriers after a new diagnosis of GD and increase the percentage of patients attaining an euthyroid state within 3 months from diagnosis and sustain for 12 months.

METHODS

Using standard QI methodologies from January to November 2023, our plan, do, study, act cycles focused on an educational handout and checklist at diagnosis, a standardized methimazole dose based on initial free thyroxine (T4) and age, and frequent provider check-ins with phone call at 2 weeks, telehealth visit at 4 weeks with laboratories, and continued QI follow-up for 3 months as process measures. Outcome measure was the percentage of patients achieving normalization of free T4 level by 3 months. We used an electronic dashboard to track patients.

RESULTS

Of the 46 patients, 76% (34) received written education; 67% (30) were initiated on standardized methimazole dosing; 80% (37) and 70% (32), respectively, attended the 2-week telephone and 1-month telehealth visits, and 83% (38) obtained 1-month laboratories. By 3 months, the outcome measure increased to 78% (36/46) from 47% (15/32) ( < 0.01), sustained at 6 months (58% versus 22%) but decreased by 12 months (45% versus 40%). Barriers included missed appointments/laboratories, language, medication adherence, and/or lack of insurance.

CONCLUSIONS

Through a multifaceted QI approach, we increased the percentage of newly diagnosed GD patients with normal free T4 levels and sustained for 6 months. Extension of follow-up is planned.
