 - **`occupied_beds` CTE** — for each patient, the latest bed assignment.
 - **Hardcoded values:**
   - `fl.root_location_id != 300` — excludes the fake beds root. Update if the fake-beds root ID changes.
+  - `fl.parent_id NOT IN (19, 44)` — excludes specific parent locations (In this case OT and casualty). Update these IDs if the excluded wards change.
   - `fl.form = 'bd'` — only bed-type facility locations.
   - `fl.status = 'active'` — only currently active beds count toward totals.
 - **`report_date` filter** — when provided, treats a bed as occupied if `start_datetime <= report_date` and (`end_datetime IS NULL` OR `end_datetime > report_date`).
