+# Open Encounters List - Arike
+
+> List of open (non-completed) encounters with patient details, staff information, and categorized tags
+
+## Purpose
+
+This query provides a comprehensive view of open patient encounters, including patient demographics, assigned nurse/doctor, and patient classification tags (zone, alerts, visit frequency, etc.). It's useful for monitoring active cases, managing patient visits, and tracking special care requirements in the Arike.
+
+## Parameters
+
+| Parameter | Type | Description | Example |
+|-----------|------|-------------|---------|
+| `staff_first_name` | TEXT | Filters by staff member's first name | `uu.first_name = 'John'` |
+| `zone_filter` | TEXT | Filters by patient zone tag | `' Zone A'` |
+| `alerts_filter` | TEXT | Filters by patient alerts tag | `'High Priority'` |
+| `frequency_filter` | TEXT | Filters by frequency of visit tag | `'Weekly'` |
+| `special_visit_filter` | TEXT | Filters by special visit tag | `'Home Visit'` |
+| `cross_subsided_model_filter` | TEXT | Filters by cross-subsidized model tag | `'Subsidized'` |
+| `Others_filter` | TEXT | Filters by other tags | `'Special Care'` |

+## Notes
+
+-  Query is filtered to `facility_id = 2` - update this value as needed
+-  Uses `config_id = 2` for admission number - verify this matches your setup
+- Only includes encounters that are NOT completed or entered_in_error (open encounters)
+- Uses MAX aggregation with CASE statements to pivot tags into columns
+- Results are ordered by encounter creation date (most recent first)
