Local Medical Guidelines in the Philippines
The Philippines has an established system for developing clinical practice guidelines through the Department of Health (DOH), though significant quality improvements are needed in their development processes.
Current Status of Philippine Guidelines
The Philippines DOH has developed and disseminates clinical practice guidelines, but most require substantial methodological improvements, particularly in rigor of development, applicability considerations, and editorial independence. 1, 2
Quality Assessment Findings
- 87 clinical practice guidelines have been developed and are currently being disseminated in the Philippines 1
- Only 1 out of 91 CPGs (1.1%) met acceptable quality standards when appraised using the AGREE II instrument 2
- Most guidelines scored well on clarity of presentation (good), scope and purpose (good), and stakeholder involvement (adequate) 2
- Critical weaknesses exist in rigor of development, applicability, and editorial independence - the domains most essential for trustworthy recommendations 2
Development Process Characteristics
- 52% of Philippine CPGs use the GRADE methodology for evidence evaluation 1
- 89% evaluate evidence for local applicability to the Philippine context 1
- 99% consider patient groups, management options, benefits, and harms 1
- 89% indicate strength of their recommendations 1
- However, only 23% consider equity in the development process 1
- Mean development duration is 1 year, with updates occurring approximately every 6 years 1
Recent Legislative Framework
The Universal Health Care Law recently enacted in the Philippines mandates the DOH to operationalize evidence-based clinical practice guideline development, signaling governmental commitment to improving guideline quality 1
Key Gaps Requiring Attention
- Funding source disclosure is present in only 72% of guidelines 1
- External technical support engagement is minimal (only 3% of CPGs) 1
- Standardized development processes are lacking, with substantial variation between different CPGs 1
- Editorial independence remains poorly addressed across most guidelines 2
Accessing Philippine Guidelines
The DOH serves as the primary source for Philippine clinical practice guidelines, though the evidence suggests that strengthening technical capacity and implementing standardized development methodology is essential before widespread implementation 2. The Research Institute for Tropical Medicine (DOH-RITM) functions as the National Reference Laboratory and follows WHO guidelines for emerging infectious diseases 3.
Common Pitfalls
- Do not assume all DOH guidelines meet international quality standards - independent appraisal shows most require revision 2
- The presence of a guideline does not guarantee methodological rigor - only half use GRADE methodology 1
- Equity considerations are frequently overlooked in Philippine CPG development 1
Recommendations for Clinicians
When using Philippine DOH guidelines, supplement them with high-quality international guidelines from organizations like WHO, and critically appraise recommendations for methodological rigor, particularly examining whether GRADE methodology was used and whether conflicts of interest were managed 1, 2. The DOH is working toward standardized CPG development processes, but until these are fully implemented, clinical judgment informed by multiple high-quality sources remains essential 1.
