Diagnostic Criteria for Thyrotoxic Crisis (Thyroid Storm)

The diagnostic criteria for thyrotoxic crisis, also known as thyroid storm, are based on clinical presentation and scoring systems. The key features of thyroid storm include:

  • Exaggerated signs and symptoms of thyrotoxicosis
  • Evidence of multiorgan decompensation
  • Inciting trigger, such as infection, surgery, or trauma
  • Clinical features, including:
    • Fever
    • Tachycardia
    • Signs of congestive heart failure
    • Vomiting/diarrhea
    • Hepatic dysfunction
    • Central nervous system disturbance

Scoring Systems

Several scoring systems are used to diagnose thyroid storm, including:

  • Burch-Wartofsky Point Scale
  • Japanese Thyroid Association diagnostic criteria These scoring systems are based on clinical criteria and can help identify patients with thyroid storm, but they may have limitations, such as lack of sensitivity in identifying milder cases or difficulty in differentiating thyroid storm from other critical conditions 1, 2.

Laboratory Assessment

Laboratory assessment can assist in the diagnosis of thyroid storm, but there is no single laboratory value that can establish a diagnosis. Thyroid hormone measurements do not differentiate between thyroid storm and uncomplicated hyperthyroidism 2, 3.

Clinical Judgment

Clinical judgment plays a crucial role in diagnosing thyroid storm, as the condition can be challenging to diagnose and manage. Healthcare providers should be aware of the clinical presentation and risk factors of thyroid storm to reduce the rate of misdiagnosis and prevent catastrophic outcomes 2, 4.
