Abstract
Objective: To perform a quality assurance study assessing if hypo- and hyperthyroidism are appropriately screened for in patients with resistant hypertension.Design: Data was collected from patients diagnosed with resistant hypertension, defined as being on four or more different classes of anti-hypertensive medications. These patients were filtered to determine if thyroid stimulating hormone (TSH) measurement occurred within 90 days of the addition of a fourth medication class.Setting: Two internal medicine residency clinics in Pittsburgh, PA.Participants: Patients were selected who had a diagnosis of hypertension and were seen in clinic between January 1, 2018 and December 23, 2020. Methods: A single center retrospective review was performed. Results: A total of 1,125 patients were identified as having resistant hypertension. Of these, only 74 patients were found to have a TSH measurement taken within 90 days of having a fourth medication class prescribed. Seven TSH values were found to be abnormal with one patient being diagnosed with hyperthyroidism, demonstrating a screening rate of 6.6%. There were statistically significant differences in age, body mass index, and diastolic blood pressure in those screened versus not.Conclusions: Thyroid disease is under-screened as an etiology for resistant hypertension, particularly given the ease of diagnosis and reversibility of these conditions.
