Bed Management Fix Summary - bed_master System

System Overview

Your hospital management system uses the NEW bed_master table for bed management (not the legacy hc_bed_master).

Database Schema

bed_master table columns:

• id - Primary key
• bed_number - Bed number/name
• bed_code - Unique bed code
• ward_id - Reference to ward_master
• bed_status - Status: 'available', 'occupied', 'maintenance', 'blocked', 'reserved', 'cleaning'
• current_ipd_id - IPD ID of patient currently occupying this bed (NULL when available)
• status - Record status: 'active', 'inactive'

How It Works

1. Bed Assignment: When a patient is admitted, bed_master.current_ipd_id is set to the IPD ID, and bed_status is set to 'occupied'
2. Bed Release: When a patient is discharged, current_ipd_id is cleared (set to NULL) and bed_status is set to 'available'
3. Bed Status Dashboard: Queries bed_master joining with ipd_master on current_ipd_id to show current occupancy

Issues Identified

1. Beds Not Released on Discharge

Problem: When patients are discharged (ipd_status = 1), beds remain occupied:

• bed_master.bed_status still shows 'occupied'
• bed_master.current_ipd_id still has the IPD ID instead of NULL

Impact: Bed status dashboard shows 5 occupied beds but only 1 current admission, causing confusion and preventing bed reuse for new patients.

2. Blank "Bed Assign" Column

Problem: The Current Admission view may show blank in the "Bed No [Type]" column.

Root Cause: The query looks for beds where current_ipd_id matches the IPD, but if discharge didn't clear this field, the join fails.

Solutions Implemented

Fix 1: Add Bed Release Logic

File: app/Models/IpdModel.php

Added new method releaseBed(int $ipdId) that:

1. Clears current_ipd_id (sets to NULL) in bed_master table
2. Sets bed_status = 'available' in bed_master table
3. Updates bed_assignment_history with release date and reason (if that table is used)
4. Also handles legacy hc_bed_master for backward compatibility (if it exists)

Fix 2: Call Bed Release on Discharge

File: app/Controllers/Billing/Ipd.php

Modified the updateDischargeStatus() method to call releaseBed() when ipd_status is set to 1.

Fix 3: Update Bed Assignment Logic

File: app/Models/IpdModel.php

Updated bedAssign() method to:

1. Set bed_master.current_ipd_id to the IPD ID when assigning
2. Set bed_master.bed_status to 'occupied'
3. Clear any previous bed assigned to the same IPD (in case of bed transfer)

Additional Recommendations

1. Run the SQL Fix to Clean Up Existing Data

For existing IPDs where beds weren't released properly, run the SQL script fix_bed_management.sql:

Main fix (Step 2):

UPDATE bed_master bm
INNER JOIN ipd_master i ON i.id = bm.current_ipd_id
SET 
    bm.bed_status = 'available',
    bm.current_ipd_id = NULL
WHERE i.ipd_status = 1
AND bm.current_ipd_id IS NOT NULL;

This releases all beds for patients who have been discharged.

2. Verify the Fix

After running the SQL, check the verification queries (Step 4) to confirm:

• All discharged patients' beds show as available
• Occupied bed count matches current admission count
• No beds have status mismatch

3. Monitor Bed Management

Use these pages to monitor:

• /setting/admin/bed-status - View current bed occupancy by ward/floor
• /setting/admin/bed-management - Manage bed master data
• /billing/ipd/current-admission - View patients with their assigned beds

Testing Checklist

1. Test Bed Assignment:

   • Admit a new patient
   • Assign a bed
   • Verify bed_master.bed_status = 'occupied'
   • Verify bed_master.current_ipd_id = IPD ID

2. Test Discharge:

   • Discharge a patient
   • Verify bed_master.bed_status = 'available'
   • Verify bed_master.current_ipd_id IS NULL

3. Test Current Admission View:

   • Open /billing/ipd/current-admission
   • Verify "Bed No [Type]" column shows bed information
   • Verify all admitted patients show their bed assignments

4. Test Bed Status Panel:

   • Open /setting/admin/bed-status
   • Verify Available count is correct
   • Verify Occupied count matches current admissions
   • Click on occupied beds to see patient details

Files Modified

1. app/Models/IpdModel.php

   • Updated releaseBed() method - releases beds on discharge
   • Updated bedAssign() method - sets current_ipd_id when assigning

2. app/Controllers/Billing/Ipd.php

   • Modified updateDischargeStatus() to call bed release

3. fix_bed_management.sql

   • SQL script to fix existing data (discharged patients' beds)

Database Schema Reference

Tables Used

1. bed_master (Primary table - NEW system)

   • bed_status: 'available' | 'occupied' | 'maintenance' | 'blocked' | 'reserved' | 'cleaning'
   • current_ipd_id: IPD ID using this bed (NULL = available)
   • bed_number: Bed identifier
   • bed_code: Unique code
   • ward_id: Reference to ward_master
   • status: 'active' | 'inactive'

2. bed_assignment_history (Optional tracking table)

   • Records all bed assignments with dates
   • released_date: When bed was freed
   • release_reason: Why bed was freed
   • Provides audit trail for bed usage

3. ipd_master (Patient admission records)

   • ipd_status: 0=admitted, 1=discharged
   • register_date: Admission date
   • discharge_date: Discharge date

4. ward_master (Ward/room information)

   • ward_name: Ward/room name
   • floor_number: Floor level
   • ward_type: Type of ward

How Bed Management Works Now

Bed Assignment Flow:

1. Patient admitted to IPD
2. Bed selected from available beds
3. IpdModel::bedAssign() called:
   • Creates entry in bed_assignment_history
   • Sets bed_master.current_ipd_id = IPD ID
   • Sets bed_master.bed_status = 'occupied'

Bed Release Flow:

1. Patient discharged (ipd_status = 1)
2. IpdModel::releaseBed() called automatically:
   • Sets bed_master.current_ipd_id = NULL
   • Sets bed_master.bed_status = 'available'
   • Updates bed_assignment_history.released_date

Bed Status Dashboard Query:

SELECT b.*, i.ipd_code, i.register_date, p.p_fname
FROM bed_master b
LEFT JOIN ipd_master i ON i.id = b.current_ipd_id AND i.ipd_status = 0
LEFT JOIN patient_master p ON p.id = i.p_id
WHERE b.status = 'active'

Implementation Notes

• Legacy hc_bed_master support kept for backward compatibility (optional)
• Main system now uses bed_master exclusively
• current_ipd_id is the key field linking beds to patients
• Bed status transitions: available → occupied → available

Support

If issues persist after running the fix:

1. Check ipd_master.ipd_status (0=admitted, 1=discharged)
2. Check bed_master.current_ipd_id values (should be NULL for available beds)
3. Check bed_master.bed_status values (should match occupancy)
4. Review application logs for errors in IpdModel methods
5. Run the verification queries from Step 4 in the SQL script
6. Check /setting/admin/bed-status dashboard for accurate counts

Quick Troubleshooting

Problem: Beds still show occupied after discharge

• Solution: Run Step 2 of fix_bed_management.sql

Problem: "Bed Assign" column is blank

• Solution: Ensure bed_master.current_ipd_id is set during admission

Problem: Bed count mismatch

• Solution: Run verification queries (Step 4) to identify discrepancies

Problem: Cannot assign bed (shows as occupied)

• Solution: Check if current_ipd_id is stuck with old IPD - run fix SQL
