# 🔧 Fix: IPC Variables Now Passed to InfectoGuard Agents

## Problem

After the initial clinical variables fix, **IPC agents** (InfectoGuard) were still asking for information already provided in Patient Card B (CLABSI case).

### User's Test Result:
```
User: "Please evaluate this case for NHSN CLABSI criteria..."

InfectoGuard Response:
"I can do that — I'll need a brief case summary to apply NHSN CLABSI criteria..."
[Long list of required information that was already in the IPC variables]
```

## Root Cause

The initial fix added:
- ✅ Clinical assessment variables → Clinical agents
- ✅ Orchestrator variables → Orchestrators
- ❌ **IPC variables → IPC agents** (MISSING!)

The IPC logic at line 1807 was for **jurisdiction-based reporting requirements** (Texas, CDC, etc.), not for passing the actual **case data** from the UI fields.

## Solution

Added IPC variable extraction block in `chatpanel_handle_with_dynamic_vars`:

```python
# IPC tools (IPC_reporting, NHSN_criteria_evaluator, recommend_isolation_precautions)
elif "IPC_reporting" in skills or "NHSN_criteria_evaluator" in skills or "recommend_isolation_precautions" in skills:
    var_names = [
        "facility_name", "location_unit", "infection_type", "onset_date", "device_days",
        "pathogen", "resistance_pattern", "isolation_status", "compliance_issues"
    ]
    user_vars = {
        "facility_name": ipc_facility_name,
        "location_unit": ipc_location,
        "infection_type": ipc_infection_type,
        "onset_date": ipc_onset_date,
        "device_days": ipc_device_days,
        "pathogen": ipc_pathogen,
        "resistance_pattern": ipc_resistance_pattern,
        "isolation_status": ipc_isolation_status,
        "compliance_issues": ipc_compliance_issues
    }
    extracted = extract_clinical_variables_from_history(history, var_names)
    for k in var_names:
        if not user_vars[k]:
            user_vars[k] = extracted.get(k) or ""
    # Prepend IPC data if at least one field is non-empty
    if any(user_vars[k] for k in var_names):
        user_text = f"[IPC_CONTEXT] {json.dumps(user_vars)}\n" + user_text
```

## What This Fixes

### IPC Variables Now Passed (9 fields):
1. **Facility Name** → Methodist Hospital, Dallas, Texas
2. **Location/Unit** → ICU, Medical Ward 3B
3. **Infection Type** → CLABSI
4. **Onset Date** → 2025-03-15
5. **Device Days** → 7 days (central line in place)
6. **Pathogen** → MRSA
7. **Resistance Pattern** → Methicillin-resistant
8. **Isolation Status** → Contact precautions initiated
9. **Compliance Issues** → Line inserted emergently without full barrier precautions

### Agent Skills That Trigger IPC Context:
- `IPC_reporting` - For generating IPC reports
- `NHSN_criteria_evaluator` - For NHSN surveillance definitions
- `recommend_isolation_precautions` - For isolation recommendations

### Format:
```json
[IPC_CONTEXT] {
  "facility_name": "Methodist Hospital, Dallas, Texas",
  "location_unit": "ICU, Medical Ward 3B",
  "infection_type": "CLABSI",
  "onset_date": "2025-03-15",
  "device_days": "7 days (central line in place)",
  "pathogen": "MRSA",
  "resistance_pattern": "Methicillin-resistant",
  "isolation_status": "Contact precautions initiated",
  "compliance_issues": "Line inserted emergently without full barrier precautions"
}
```

## Expected Results After Fix

### Before Fix:
```
User: "Please evaluate this case for NHSN CLABSI criteria..."

Agent: ❌ "I'll need a brief case summary to apply NHSN CLABSI criteria.
        What I need from you to evaluate the case (minimum):
        - Presence/type of central venous catheter...
        - Date/time of symptom onset...
        - Blood culture data...
        [Long list of already-provided information]"
```

### After Fix:
```
User: "Please evaluate this case for NHSN CLABSI criteria..."

Agent: ✅ "Based on the case data from Methodist Hospital ICU:
        
        NHSN CLABSI Criteria Evaluation:
        ✅ MBI-LCBI Criterion 1 met:
           - Recognized pathogen (MRSA) from blood culture
           - Central line in place on 2025-03-15
           - 7 device days documented
        
        Isolation Precautions:
        ✅ Contact precautions appropriate for MRSA
        
        Key IPC Priorities:
        - Line removal (source control)
        - NHSN surveillance reporting required
        - Bundle compliance audit (full barrier precautions not used)
        ..."
```

## Testing Instructions

### Test Patient Card B + InfectoGuard:

1. **Navigate to**: https://huggingface.co/spaces/John-jero/IDWeekAgents
2. **Wait**: ~2-3 minutes for space rebuild
3. **Select**: InfectoGuard agent
4. **Click**: Patient Card B (CLABSI case)
5. **Verify**: IPC variables section populates with:
   - Methodist Hospital, Dallas, Texas
   - ICU location
   - CLABSI infection type
   - MRSA pathogen
   - 7 device days
   - Contact precautions status
6. **Ask**: "Please evaluate this case for NHSN CLABSI criteria and recommend appropriate isolation precautions."
7. **Expected**: ✅ Agent uses provided data, evaluates NHSN criteria, makes specific recommendations
