+
+## Notes
+
+- **Hardcoded IDs:**
+  - `questionnaire_id = 68` — the doctor visit questionnaire at Karunashraya.
+- **`organization_id` is required** (no `[[...]]` wrapper) — the query will not run without a value.
+- Results are ordered by visit count descending, then alphabetically by facility name for ties.
