Patients with noninfectious pseudobacterial dermatological conditions experienced greater odds for unnecessary exposure to antibiotics, a recent study found. Additional independent risk factors included rural settings and diminished access to specialist care. This observational prospective study included 207 participants referred to an academic dermatology referral center for acute skin conditions which were ultimately deemed to be of a nonbacterial cause. Preceding antibiotic prescription, final diagnosis, and patient and provider characteristics were reviewed. Researchers found:

• Antibiotic prescriptions were provided to 31/207 individuals.
• Patients with pseudobacterial diagnoses (66/207 individuals) had 4.79 times the odds of empiric antibiotic treatment compared to all others.
• Rural referring providers and referring providers in areas with a low density of medical specialists also displayed increased odds of empiric antibiotic prescription for nonbacterial skin disease, though the former finding may be limited by the low number of rural vs urban providers (7 vs 200) included in the study.
