+# Discharged but Incomplete IP Encounters - SSMM
+
+> IP encounters that were marked as discharged more than a day ago but are still not marked as completed
+## Purpose
+
+Identifies in-patient (`encounter_class = 'imp'`) encounters at SSMM whose status history shows a `discharged` event more than 1 day ago, yet the encounter's current `status` is **not** `completed`.
+
+## Parameters
+
+*This query has no parameters.*
+
+---
+
+## Query
+
+```sql
+SELECT 
+    p.name AS patient_name,
+    pi.value AS ssmm_id,
+    (e.period->>'end')::timestamp AT TIME ZONE 'UTC' AT TIME ZONE 'Asia/Kolkata' AS discharged_datetime,
+    e.status AS current_status
+FROM emr_encounter e
+JOIN emr_patient p ON p.id = e.patient_id
+LEFT JOIN emr_patientidentifier pi 
+    ON pi.patient_id = p.id
+   AND pi.config_id = 21
+WHERE e.encounter_class = 'imp'
+  AND e.deleted = FALSE
+  AND e.status != 'completed'
+  AND e.period->>'end' IS NOT NULL
+  AND e.status_history->'history' @> '[{"status": "discharged"}]'::jsonb
+  AND (e.period->>'end')::timestamp AT TIME ZONE 'UTC' AT TIME ZONE 'Asia/Kolkata'
+      < CURRENT_TIMESTAMP - INTERVAL '1 day'
+  AND EXISTS (
+      SELECT 1
+      FROM emr_facilitylocationencounter fle
+      JOIN emr_facilitylocation fl ON fl.id = fle.location_id
+      WHERE fle.encounter_id = e.id
+        AND fl.form = 'bd'
+        AND fl.root_location_id != 300
+  )
+ORDER BY p.name;
+```
+
+
+## Notes
+
+- **Hardcoded values:**
+  - `pi.config_id = 21` — SSMM patient identifier configuration.
+  - `fl.root_location_id != 300` — excludes fake beds.
+  - `fl.form = 'bd'` — only bed-type facility locations.
+- This query has no Metabase parameters; the date threshold is fixed at "more than 1 day ago".
