Clinical QuickieInfectious Disease
Post-Discharge Fever / Persistent Infection Symptoms
Persistent symptoms after discharge require reassessment — not automatic extension of the original treatment.
Start with the original diagnosis
Confirm what infection was treated, what organism/data supported it, what therapy was prescribed, and whether source control was achieved.
Ask whether the trajectory fits
Some symptoms resolve gradually. New fever, recurrent fever, worsening pain, new hypoxemia, hypotension, confusion, or declining function suggests a different trajectory.
Think failure, complication, or new process
Nonadherence, resistance, inadequate source control, abscess, device infection, C. difficile, drug fever, thrombosis, and a new infection can all mimic 'the same infection coming back.'
Re-test with purpose
Repeat cultures, imaging, CBC/CMP, urinalysis, or other testing only when the clinical picture supports a question they can answer.
