Best Practices

1. Use create_codeable_concept with LOINC codes when available for standardized social history
2. Be non-judgmental in documentation - focus on health relevance
3. Include quantitative details when possible (pack-years, drinks per week)
4. Document both current status and historical information
5. Update lifestyle factors periodically as they may change
6. Include relevant timeframes for risk assessment
7. Consider cultural and social context in documentation
