Management of Patients with Subclinical Hypothyroidism in Primary Care
Abstract:
Subclinical hypothyroidism (SCH) is defined as a raised serum thyroid stimulating hormone level with normal thyroxine. Despite a prevalence of up to 9% of the adult population there is widespread uncertainty on how to manage it. The aim of this study was to assess how older adults with SCH are managed in primary care. A retrospective case-note review was carried out on patients attending Mallow Primary Healthcare Centre. This study identified patients 65 years and over meeting the criteria for SCH in one year. The prevalence of SCH in this study was calculated as 2.9%. 22.2% of patients were treated with thyroxine. 6.1% of untreated patients progressed to clinical hypothyroidism within the study period while 18.2% spontaneously reverted to normal TSH levels.

Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
