Antimicrobial stewardship emphasizes selecting the appropriate agent, dose, and duration while minimizing unnecessary broad-spectrum coverage to prevent resistance. Match each of the following common infectious disease presentations with the most appropriate guideline-concordant initial management strategy.
- A 28-year-old non-pregnant woman presenting with dysuria, urinary frequency, and suprapubic pain, without fever or costovertebral angle tenderness.Oral nitrofurantoin, fosfomycin, or trimethoprim-sulfamethoxazole
- A 45-year-old otherwise healthy man with a 2.5 cm fluctuant, erythematous cutaneous abscess on his back and normal vital signs.Incision and drainage without systemic antimicrobial therapy
- A 50-year-old healthy woman with unilateral, spreading erythema and warmth on her lower leg, without fluctuance, purulence, or systemic toxicity.Oral cephalexin, dicloxacillin, or penicillin V
- A 35-year-old previously healthy man presenting with a 3-day history of productive cough, fever, and focal crackles, with no medical comorbidities.High-dose oral amoxicillin or doxycycline
Answer
Uncomplicated cystitis requires nitrofurantoin or fosfomycin; a simple cutaneous abscess requires only incision and drainage; non-purulent cellulitis is managed with targeted beta-lactams (e.g., cephalexin); and uncomplicated outpatient community-acquired pneumonia is treated with amoxicillin or doxycycline.
Each presentation is accurately matched to its guideline-recommended empiric therapy. The choices highlight key stewardship concepts: avoiding fluoroquinolones in simple cystitis, relying on source control for simple abscesses, targeting streptococci rather than MRSA in non-purulent cellulitis, and utilizing amoxicillin or doxycycline for uncomplicated outpatient pneumonia.
