Adaptation of Cost Analysis Studies in Practice Guidelines

Area of Science:

• Health Economics
• Clinical Practice Guidelines
• Health Services Research

Background:

• Clinical guidelines are essential for daily medical practice.
• Incorporating cost analyses into guidelines can optimize resource allocation.
• The extent to which cost analyses are integrated into clinical guidelines is not well understood.

Purpose of the Study:

• To assess the incorporation of cost analyses into clinical guidelines.
• To identify factors influencing the level of cost analysis integration.
• To evaluate the quality of incorporated cost analyses.

Main Methods:

• Analysis of 100 highly cited clinical guidelines from the National Guideline Clearinghouse.
• Quantification of cost analysis incorporation and comparison across medical specialties.
• Case-control study matching incorporated and non-incorporated cost analyses based on Consolidated Health Economic Evaluation Reporting Standards (CHEERS) criteria.

Main Results:

• 57% of guidelines lacked cost justification.
• Guidelines incorporated only 6% of available cost analyses, with significant variation by specialty.
• Incorporated analyses showed better adherence to CHEERS requirements, stronger links between cost reduction and outcomes, and more frequent funding source disclosure.

Conclusions:

• Clinical guidelines underutilize cost analyses for efficient resource allocation.
• Enhancing adherence to reporting standards like CHEERS and transparently reporting funding sources may increase guideline developers' use of cost analyses.
