Immunization Gap Agent

The work it takes off your plate

Immunization records are fragmented across state registries, EHRs, pharmacies, and paper cards, so care teams cannot reliably see who is due or overdue against ACIP schedules. Manual gap lists are stale, ignore contraindications and catch-up logic, and produce low-yield outreach that frustrates patients. The Immunization Gap Agent reconciles multi-source vaccine history, applies ACIP age- and risk-based rules, and drives scheduling plus targeted campaigns to close preventive immunization gaps.

How it works

The agent consolidates immunization history, evaluates each patient against ACIP recommendations including catch-up and high-risk indications, suppresses invalid or contraindicated recommendations, and orchestrates outreach and appointment slots for due vaccines with documentation of administration or refusal.

1. Step 1: Reconcile Immunization History

   • Ingest EHR immunizations, IIS/state registry queries, pharmacy claims, and patient-reported vaccines
   • Deduplicate doses by CVX/MVX, date, and lot where available
   • Flag conflicts (e.g., mismatched product or impossible spacing) for clinical review

   Result: A reconciled immunization forecast baseline per patient with source provenance.

2. Step 2: Apply ACIP Schedule and Gap Logic

   • Evaluate age-based, seasonal, and risk-based recommendations (influenza, COVID-19, pneumococcal, shingles, HPV, Tdap, childhood series)
   • Apply catch-up schedules, minimum intervals, and series completion rules
   • Suppress recommendations for allergies, pregnancy timing, recent dose, or documented immunity

   Result: Validated due/overdue vaccine list with clinical rationale and urgency.

3. Step 3: Drive Scheduling and Outreach Campaigns

   • Segment campaigns by vaccine type, age band, and clinic capacity
   • Send reminders via portal, SMS, and mail with self-scheduling or nurse clinic slots
   • Coordinate standing-order nurse visits and pharmacy partnership pathways where allowed

   Result: Patients booked or reminded with campaign metrics by vaccine and site.

4. Step 4: Document Closure and Report Coverage

   • Capture administered doses, patient refusals, and deferrals with reason codes
   • Write back to EHR and initiate IIS submission where configured
   • Publish coverage rates, gap closure velocity, and equity stratifications

   Result: Updated records and population coverage dashboards for quality and public health reporting.

Why use it

• ACIP-Aligned Forecasts. Age, risk, and catch-up logic built in.
• Multi-Source Reconciliation. EHR + IIS + pharmacy reduce false gaps.
• Campaign Automation. Segmented outreach with scheduling links.
• Safety Guards. Contraindication and interval checks before recommending.
• Coverage Analytics. Real-time rates for quality programs and public health.
