Outpatient parenteral antibiotic therapy (OPAT) and inpatient treatment strategies for emergency department patients with cellulitis: a cost analysis.

This is the first Canadian study that compares the cost of different OPAT strategies for cellulitis patients. While both OPAT strategies are safe and far less costly than hospital admission, our findings suggest that a dedicated OPAT clinic for patients with cellulitis is more expensive than the return to ED strategy.
