Antibiotic Stewardship in Dermatology

Overview / Definition Antibiotic stewardship refers to a set of coordinated strategies to improve the use of antibiotic medications. In dermatology, it aims to ensure that patients receive the most appropriate antibiotic therapy for their skin infections while minimizing unnecessary prescriptions, thereby combating antibiotic resistance. Epidemiology Skin and soft tissue infections (SSTIs) are among the most common reasons for antibiotic prescriptions in dermatology. The emergence of multidrug-resistant organisms (MDROs) has significantly altered the landscape of treatment options. Key epidemiological findings include: Approximately 10% of dermatology visits are for infections. Staphylococcus aureus, particularly methicillin-resistant Staphylococcus aureus (MRSA), is a common pathogen. Incidence of antibiotic-resistant infections is rising, making stewardship critical. Pathophysiology / Mechanism Understanding the mechanisms of resistance is crucial for effective antibiotic stewardship. Key points include: Resistance can arise through genetic mutations or acquisition of resistance genes. Biofilms can protect bacteria from both the host immune response and antibiotic penetration. Overuse and misuse of antibiotics accelerate the development of resistance. Clinical Presentation Patients with skin infections may present with a variety of symptoms, including: Localized erythema and warmth Pain and tenderness at the site of infection Purulent drainage or abscess formation Systemic symptoms such as fever and malaise in severe cases Diagnosis / Workup Accurate diagnosis is essential for effective management. Diagnostic steps include: Clinical examination to assess the extent and characteristics of the infection. Culture and sensitivity tests to identify the causative organism. Consideration of imaging studies for deeper infections. Assessment for systemic involvement if indicated. Treatment / Management Management of infections must be guided by local resistance patterns an
