Thyroid dysfunction is common in elderly hospital patients, affecting over a third. Early screening for thyroid issues in this population is recommended to improve care.

Area of Science:

  • Geriatric Medicine
  • Endocrinology
  • Internal Medicine

Background:

  • Elderly in-patient populations often present complex health challenges.
  • Thyroid dysfunction is a common endocrine disorder with significant health implications.

Purpose of the Study:

  • To determine the prevalence of thyroid dysfunction in elderly inpatients.
  • To assess the association of thyroid dysfunction with clinical factors in this demographic.

Main Methods:

  • Prospective observational study in a geriatric ward.
  • Screening of 184 consecutive elderly inpatients over 3 months.
  • Thyroid function tests (free thyroxine, thyroid stimulating hormone) and further investigations for abnormal results.

Main Results:

  • A high prevalence of thyroid dysfunction was observed, with 62 (33.7%) patients showing abnormal thyroid function tests.
  • Common conditions included sick euthyroid syndrome (17.9%), secondary hypothyroidism (8.2%), and primary hypothyroidism (4.9%).
  • No significant association was found between sick euthyroid syndrome and sepsis, hypoalbuminemia, or functional dependence.

Conclusions:

  • Thyroid dysfunction is highly prevalent in elderly inpatients.
  • A lower threshold for screening elderly inpatients for thyroid dysfunction is advocated.
  • Early detection and management of thyroid disorders can improve patient outcomes.
