Educational Pearls:
How fast does cellulitis recover?
-
A recent prospective cohort study took a look at this question.
-
The study included 300 adults with cellulitis (excluding those with peri-orbital cellulitis or abscesses) in two emergency departments in Queensland, Australia.
-
They collected data from initial and follow-up surveys at 3, 7, and 14 days, and compared clinician and patient assessments at day 14.
-
Improvement was fastest between day 0 and day 3, with gradual progress thereafter.
-
At day 14, many still had skin redness and swelling, though warmth had often resolved. Clinicians reported higher cure rates than patients (85.8% vs. 52.8%).
-
Conclusion:
-
Cellulitis symptoms improve quickly at first but continue to linger for many patients.
-
Patients and doctors often have different views on when cellulitis is fully cured.
How should we counsel patients?
-
Even on antibiotics, the margins of the cellulitis may continue to spread a small amount.
-
Skin warmth should be the first symptom to go away.
-
It takes time to get better. Only about 50% of patients believed their cellulitis was cured at 2 weeks.
