Cellulitis is a commonly occurring acute bacterial skin infection of the dermis and subcutaneous skin. In the United States, there are approximately 14.5 million cases of cellulitis annually, resulting in 650 000 hospital admissions.1 The Infectious Disease Society of America (IDSA) released evidence-based guidelines that advise against imaging except in patients with cellulitis and febrile neutropenia, and against blood cultures except in patients who were highly immunocompromised, exhibiting systemic toxic effects, or who had sustained animal bites.2 This study evaluates the clinical usefulness and cost of blood cultures and imaging in patients with presumed cellulitis.
