Diagnosing pelvic inflammatory disease. A comprehensive analysis and considerations for developing a new model.

Area of Science:

• Gynecology
• Infectious Diseases
• Diagnostic Medicine

Background:

• Pelvic inflammatory disease (PID) diagnosis relies on various indicators, but their accuracy is debated.
• Existing diagnostic criteria may lack sufficient sensitivity or specificity for reliable identification of PID.

Purpose of the Study:

• To critically evaluate the diagnostic accuracy of current indicators for pelvic inflammatory disease (PID).
• To propose guidelines for a novel diagnostic model for PID, aiming to improve accuracy and clinical utility.

Main Methods:

• Systematic review of English-language literature from 1969-1990 on PID diagnosis.
• Inclusion of studies with laparoscopic confirmation or strict clinical criteria for PID diagnosis.
• Analysis of diagnostic findings categorized as historical, clinical, laboratory, or combinations, assessing sensitivity and specificity.

Main Results:

• Historical symptoms generally showed low sensitivity and high specificity for PID.
• Clinical examination findings were moderately sensitive and specific.
• Laboratory tests demonstrated consistent value, with high sensitivity and specificity for PID.
• Combinations of indicators achieved high sensitivity or high specificity, but not both simultaneously.

Conclusions:

• No single or combined indicator reliably predicts pelvic inflammatory disease (PID).
• A proposed diagnostic approach prioritizes sensitivity in mild cases and comprehensive evaluation in severe presentations.
• Further research is essential to validate new diagnostic models and explore novel indicators for PID.
