Primary Care General Tools

Description

This skill provides structured guidance for common primary care formulas and decision rules, including energy expenditure estimates, strep pharyngitis scoring, and pregnancy dating.

Quick Reference

Tool	Use
Mifflin-St Jeor	Estimate resting metabolic rate (BMR)
Harris-Benedict	Historical BMR formula
Centor Score	Strep pharyngitis risk (adult)
McIsaac Score	Modified Centor with age adjustment
Naegele's Rule	Estimate due date from LMP

Interactive Mode (Lightweight)

1. Confirm clinical context and intended tool.
2. Collect required inputs with units and timing.
3. Validate inclusion and exclusion criteria.
4. Apply tool and present results with interpretation.
5. Provide safety caveats and limitations.

Tools

• Mifflin-St Jeor
• Harris-Benedict
• Centor Score
• McIsaac Score
• Naegele's Rule

Safety and Limitations

• Support tool only; not diagnostic or prescriptive.
• Use local policies and clinical judgment.
• Many tools are validated for specific populations only.
