Statistical Analysis and Reporting of Cardiac Output Method Comparison Studies (COMPARE) Statement.

Area of Science:

• Cardiovascular Physiology
• Medical Device Validation

Background:

• Cardiac output (CO) is a critical measure of global blood flow.
• Validation studies assess the performance of CO monitoring methods against reference standards.
• Method comparison studies are vital for evaluating the accuracy of CO measurements.

Purpose of the Study:

• To introduce the StatistiCal analysis and repOrting of cardiac output Method comPARison studiEs (COMPARE) statement.
• To provide a standardized framework for designing, conducting, and reporting CO method comparison studies.
• To enhance the quality and external validity of CO validation research.

Main Methods:

• Development of the COMPARE statement, a framework for CO method comparison studies.
• Inclusion of a 29-item checklist for essential reporting elements.
• Focus on agreement analysis between test and reference CO measurement methods.

Main Results:

• The COMPARE statement offers a structured approach to CO validation studies.
• The checklist identifies 29 essential reporting items for method comparison studies.
• Adherence to the checklist promotes standardization and improves result interpretation.

Conclusions:

• Implementing the COMPARE checklist standardizes the reporting of cardiac output method comparison studies.
• Standardized reporting enhances the reliability and external validity of CO measurement validation.
• The COMPARE statement serves as a key resource for researchers in cardiovascular monitoring.
