Abnormal uterine bleeding: advantages of formal classification to patients, clinicians and researchers

Area of Science:

• Gynecology
• Reproductive Medicine
• Medical Classification Systems

Background:

• Historically, menstrual disorder research lacked funding and suffered from inconsistent terminology, hindering scientific progress.
• Diverse terminology in abnormal uterine bleeding (AUB) created confusion between clinical and research communities, weakening the evidence base.
• The International Federation of Gynecology and Obstetrics (FIGO) introduced the PALM-COEIN classification to standardize AUB causes.

Purpose of the Study:

• To underscore the clinical and scientific benefits of adopting a formal classification for abnormal uterine bleeding.
• To provide recommendations for the practical implementation of the PALM-COEIN system.
• To address challenges posed by the previous lack of standardized AUB terminology.

Main Methods:

• Review of existing literature and clinical challenges related to AUB classification.
• Development and proposal of the PALM-COEIN classification system by FIGO.
• Recommendations for local integration and application of the new system.

Main Results:

• The PALM-COEIN system provides a unified language for describing AUB causes.
• Implementation of this classification is expected to resolve historical issues in research and clinical reporting.
• The system is designed for global applicability, promoting consistency in women's health research.

Conclusions:

• The PALM-COEIN classification is a crucial tool for advancing women's health research and clinical practice.
• Global adoption will harmonize reporting and facilitate progress in understanding and treating abnormal uterine bleeding.
• This standardized system promises to improve the quality and comparability of scientific and clinical data worldwide.
