A young man presents with severe leg pain, shin abrasion, crepitus, and leg radiographs show findings; what is the most appropriate next step?

• A. Watchful waiting
• B. Transfer to ED (Suspect NSTI)
• C. Start antibiotics and discharge
• D. Admit to observation

Answer: (B)

Severe limb pain out of proportion to exam, along with crepitus and a shin abrasion, points to a necrotizing soft tissue infection. This is a fast-moving, life-threatening infection where tissue death can spread swiftly and systemic toxicity can develop within hours. The priority is urgent evaluation by the surgical team and rapid intervention to remove necrotic tissue.

Transferring the patient to the emergency department for prompt assessment is the correct move because the main goal is definitive source control through emergent surgical debridement, paired with broad-spectrum IV antibiotics and aggressive fluids. Antibiotics alone or waiting for symptoms to worsen is not enough, and discharging or simply admitting for observation would risk rapid progression. Early transfer ensures timely debridement and improves survival chances.
