Making Clinical Practice Guidelines Pragmatic: How Big Data and Real World Evidence Can Close the Gap

Area of Science:

• Medical Informatics
• Clinical Epidemiology
• Health Services Research

Background:

• Clinical practice guidelines (CPGs) are widespread but face challenges in implementation and improving health outcomes.
• Traditional randomized controlled trials (RCTs) used in CPGs have high internal validity but limited external validity, creating a gap between trial efficacy and real-world effectiveness.
• This efficacy-effectiveness gap contributes to poor physician adherence to guidelines.

Purpose of the Study:

• To explore the potential of Real World Evidence (RWE) to enhance the development and implementation of CPGs.
• To highlight how RWE can bridge the gap between clinical trial efficacy and real-world effectiveness.
• To discuss the role of RWE in advancing precision medicine within routine clinical practice.

Main Methods:

• The study conceptually integrates RWE, derived from integrated electronic health records, with traditional CPG development.
• It emphasizes leveraging collective patient and clinician experience captured in real-world data.
• The approach involves engaging frontline stakeholders in pragmatic biomarker studies to inform guideline recommendations.

Main Results:

• RWE can provide crucial data on how treatments perform in diverse, real-world patient populations, complementing RCT findings.
• Integrating RWE allows for a more balanced understanding of both efficacy and effectiveness.
• RWE facilitates precision medicine by enabling more targeted recommendations for specific patient subgroups (who and when).

Conclusions:

• RWE offers a valuable approach to enhance CPGs by addressing the limitations of traditional RCTs.
• The utilization of RWE can improve guideline adherence and health outcomes by reflecting real-world practice.
• Singapore's digital infrastructure, integrated electronic health records, and government initiatives position it favorably for leveraging RWE.
