A normative analytic framework for development of practice guidelines for specific clinical populations

Area of Science:

• Health Policy
• Clinical Decision Making
• Health Economics

Background:

• Practice guideline development faces challenges in accommodating diverse clinical populations and settings.
• A formal mechanism is lacking to assess the need for guideline flexibility and its incorporation into recommendations.

Purpose of the Study:

• To establish a formal basis for determining when clinical variations necessitate differing guideline recommendations.
• To guide the tailoring of recommendations for specific clinical settings.
• To evaluate the cost-effectiveness of developing site-specific guidelines.

Main Methods:

• Developed an approach to estimate the maximum health benefit from customizing guidelines based on population and setting variations.
• Introduced the 'expected value of customization' to assess the cost-effectiveness of site-specific guidelines.
• Applied the method to human immunodeficiency virus (HIV) screening guidelines.

Main Results:

• Site-specific guidelines for HIV screening show potential cost-effectiveness.
• These tailored guidelines can improve or maintain the efficiency of HIV screening.
• Impact on overall expenditures and health benefits depends on cost-effectiveness thresholds and clinical context.

Conclusions:

• Decision model-based guideline development offers a normative framework for evaluating site-specific guidelines.
• Tailored, site-specific guidelines can significantly enhance expected health benefits.
• Economic efficiency of practice guidelines can be substantially improved through customization.
