PALM-COEIN Nomenclature for Abnormal Uterine Bleeding

Area of Science:

• Gynecology
• Reproductive Health
• Medical Terminology

Background:

• Abnormal uterine bleeding (AUB) affects approximately 30% of women.
• Previous terminology for AUB was confusing and inconsistently applied, hindering clinical management and research.
• Standardized nomenclature is crucial for effective diagnosis and treatment of AUB.

Purpose of the Study:

• To introduce and describe the PALM-COEIN classification system for abnormal uterine bleeding (AUB) in reproductive-aged women.
• To promote the adoption of standardized terminology for AUB to improve clinical practice and research.
• To outline treatment options associated with each category within the PALM-COEIN system.

Main Methods:

• Review and presentation of the PALM-COEIN classification system developed by the International Federation of Gynecology and Obstetrics (FIGO) Menstrual Disorders Group (FMDG).
• Explanation of the standardized nomenclature designed to describe the etiology and severity of AUB.
• Discussion of treatment strategies corresponding to the etiological categories within the PALM-COEIN framework.

Main Results:

• The PALM-COEIN system provides a standardized approach to classifying the causes of AUB.
• Outdated terms like menorrhagia and dysfunctional uterine bleeding are no longer recommended.
• The system facilitates consistent reporting and understanding of AUB among clinicians.

Conclusions:

• The PALM-COEIN classification system is essential for standardizing the description and management of abnormal uterine bleeding.
• Clinicians should utilize the PALM-COEIN system when encountering and reporting on AUB cases.
• Standardized nomenclature will enhance the quality of care and research in AUB.
