Hypothyroidism General Medicine Conference
Screening • Should it be done? • Argue for: • Common • Prevalence = 4-10% for mild thyroid failure in the general population (18% in the elderly) • Cost effective • Has been estimated to be as cost-effective as other generally recommended screenings such as mammography
Screening • Should it be done? • Argue for: • Common • Prevalence = 4-10% for mild thyroid failure in the general population (18% in the elderly) • Cost effective • Validated test
Screening • Argue against: • Does it lower morbidity? • (especially compared with “high-risk” screening)
Recommendations for Selective Screening • AACE • Older patients, especially women • ATA • Women over 60 • History of thyroid disease • Autoimmune disease • Unexplained depression • Cognitive dysfunction • Hypercholesterolemia • ACP/ABIM • Women over 50 years old
Screening • What about pre-pregnancy or early pregnancy evaluation? • Hypothyroidism in the mother is associated with: • Placental abruption • Preterm delivery • Perinatal intraventricular hemorrhage • Infant respiratory distress syndrome • Lower child IQ scores
Screening • An “expert panel” has found insufficient evidence to recommend for or against routine TSH testing in pre/early pregnancy but did recommend “high-risk” screening. • JAMA 2004 • A separate “panel of experts” (AACE and Endocrine Society) strongly disagrees with this and does recommend routine TSH testing in all women for pre/early pregnancy evaluations. • J Clin Endo/Metab 2005
