Direct Discharge of Pediatric Shoulder Injuries Without Red Flags
Yes, you can safely discharge a child with a shoulder injury from the emergency department if there are no red-flag findings, with instructions to return if symptoms do not improve within one week.
Evidence-Based Discharge Approach
The ACR Appropriateness Criteria for traumatic shoulder pain 1, 2 establishes that radiography is the preferred initial study and can effectively rule out the primary concerns requiring acute intervention: displaced fractures and shoulder malalignment. Once these are excluded through proper imaging, most soft-tissue injuries (rotator cuff tears, labral tears, low-grade acromioclavicular separations) can undergo conservative management before considering surgery 1.
What Constitutes "No Red Flags"
Before discharge, ensure you have excluded:
- Displaced or unstable fractures on radiographs (minimum 3 views: AP internal/external rotation plus axillary or scapula-Y view) 1, 2
- Glenohumeral or acromioclavicular dislocation (axillary/scapula-Y views are vital as dislocations can be missed on AP views alone) 1
- Neurovascular compromise on physical examination
- Open injuries or significant soft tissue damage
- Inability to tolerate oral pain medication
- Concerning mechanism suggesting high-energy trauma
Discharge Protocol
Recent evidence strongly supports direct discharge of simple stable musculoskeletal injuries 3, 4. Studies demonstrate that direct discharge from the ED:
- Reduces healthcare utilization by 1.68 hospital visits per patient 4
- Maintains equivalent functional outcomes and treatment satisfaction 4
- Shows low return rates (0.0-19.4%) 3
- Reduces costs by €69-€210 per patient 3
Specific Discharge Instructions Must Include:
- Pain management plan with specific oral analgesics and dosing
- Activity restrictions - sling use for comfort, avoid overhead activities
- Red-flag symptoms requiring immediate return:
- Increasing pain despite medication
- New numbness/tingling
- Inability to move the arm
- Fever or signs of infection
- Clear timeline - return if no improvement in 7 days
- Follow-up arrangement - either scheduled appointment or clear instructions on how to access care 5, 6
Critical Pitfall to Avoid
Never discharge without adequate radiographic evaluation. The ACR guidelines emphasize that radiographs must include axillary or scapula-Y views 1, 2 - AP views alone are insufficient as they can miss dislocations. Upright radiographs are preferred over supine as malalignment can be underrepresented 1.
One-Week Return Instruction Rationale
The one-week timeframe is appropriate because:
- Most simple soft-tissue injuries show improvement with conservative management within this period 1
- Persistent symptoms beyond one week may warrant advanced imaging (MRI) to evaluate for rotator cuff or labral pathology that might benefit from earlier intervention 2
- This approach aligns with evidence showing most soft-tissue injuries can undergo conservative management before considering surgery 1
The key is ensuring proper initial imaging has excluded injuries requiring acute surgical management, providing clear discharge instructions with specific red-flag symptoms, and establishing accessible follow-up care 3, 4.
