HIPAA-Compliant Patient Risk Stratification Pivot Model

Create an advanced Excel dashboard that anonymizes patient data while developing a multi-factor risk stratification model using conditional formatting and pivot tables. The model must incorporate age, comorbidity scores, medication complexity, and recent hospitalization frequency. Develop a color-coded heat map that allows healthcare administrators to quickly identify high-risk patient populations without exposing personally identifiable information. Include data validation rules to prevent accidental PHI exposure and implement VBA macros for automated quarterly reporting.
