chronic-disease-registry-query

Builds and queries disease registries from FHIR data for diabetes, hypertension, COPD, asthma, CHF, and CKD. Generates patient counts, severity distributions, treatment patterns, and outcome trends. Use when user asks to "query registry", "disease registry", "registry report", "how many patients with [condition]", "severity breakdown", "treatment patterns", "disease outcomes", or mentions "registry management", "chronic disease tracking". Do NOT use for individual patient review, quality measure calculation (use quality-measure-dashboard), or general panel overview without disease-specific depth (use patient-panel-overview).
