[A new thyrotoxicosis index (bases for calculation and applications)]

Area of Science:

• Endocrinology
• Internal Medicine
• Clinical Diagnostics

Background:

• Thyrotoxicosis diagnosis can be challenging, often requiring complex assessments.
• Distinguishing true thyrotoxicosis from pseudo-thyrotoxicosis necessitates reliable diagnostic tools.

Purpose of the Study:

• To develop and validate a new thyrotoxicosis index (pointer) for improved diagnostic accuracy.
• To assess the index's performance across a large, computerized patient cohort.

Main Methods:

• A new index was calculated based on the frequency of signs and symptoms.
• The index was developed using a documented population of 189 thyrotoxicosis and pseudo-thyrotoxicosis patients.
• The index was applied to a computerized population of 3,596 patients with thyroid complaints.

Main Results:

• The index effectively stratified patients into four diagnostic groups.
• High index scores (≥8.5) indicated a high probability of thyrotoxicosis (92.5% certainty).
• Low index scores (≤-1) strongly suggested the absence of thyrotoxicosis (98% certainty).

Conclusions:

• The developed thyrotoxicosis index is a valuable tool for differentiating thyrotoxicosis.
• This index offers a practical and accurate method for assessing thyroid status in patients.
• The index facilitates clearer patient categorization, aiding clinical decision-making.
