+# 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
+WITH first_discharged AS (
+    SELECT DISTINCT ON (e.id)
+        e.id AS encounter_id,
+        e.status AS current_status,
+        (discharged_status->>'moved_at')::timestamp + INTERVAL '5 hours 30 minutes' AS discharged_datetime
+    FROM emr_encounter e
+    CROSS JOIN LATERAL jsonb_array_elements(e.status_history->'history') AS discharged_status

+      AND e.deleted = FALSE
+      AND discharged_status->>'status' = 'discharged'
+      AND e.status != 'completed'
+    ORDER BY e.id, (discharged_status->>'moved_at')::timestamp

+SELECT DISTINCT ON (p.id)
+    p.name AS patient_name,
+    pi.value AS ssmm_id,
+    fd.discharged_datetime,
+    fd.current_status,
+    lb.bed_name AS latest_bed,
+    lb.bed_assigned_date
+FROM first_discharged fd
+JOIN emr_encounter e ON fd.encounter_id = e.id
+JOIN emr_patient p ON e.patient_id = p.id
+LEFT JOIN emr_patientidentifier pi
+    ON p.id = pi.patient_id
+   AND pi.config_id = 21
+LEFT JOIN latest_bed lb ON e.id = lb.encounter_id

+```

+
+## 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".
