The scope and impact of thyroid disease.

Aspects of the incidence and demographics of common thyroid disorders in the US (and elsewhere, to a lesser extent) are reviewed. The impact of healthcare reform and the efforts of managed care organizations to impose cost-effective management for the diagnosis and treatment of thyroid disorders are bringing unusual pressures to bear on both clinical laboratories and practicing endocrinologists. I discuss the potential dangers of utilization of suboptimally focused diagnostic approaches and of the inefficiencies in clinical management by primary-care providers, who often lack sufficient expertise, as opposed to endocrinologists. More than dollars are at stake, and the suboptimal management of common thyroid disorders presents several significant risks. Finally, I propose a general blueprint for the ongoing development of a structure for continuing quality improvement of the laboratory and clinical diagnosis, treatment, and long-term follow-up of patients with thyroid disease.
