ObjectiveThere is substantial practice variation in the management of cellulitis with limited prospective studies describing the course of cellulitis after diagnosis. We aimed to describe the demographics, clinical features (erythema, warmth, swelling and pain), patient-reported disease trajectory and medium-term follow-up for ED patients with cellulitis.MethodsProspective observational cohort study of adults diagnosed with cellulitis in two EDs in Southeast Queensland, Australia. Patients with (peri)orbital cellulitis and abscess were excluded. Data were obtained from a baseline questionnaire, electronic medical records and follow-up questionnaires at 3, 7 and 14 days. Clinician adjudication of day 14 cellulitis cure was compared to patient assessment. Descriptive analyses were conducted.ResultsThree-hundred patients (mean age 50 years, SD 19.9) with cellulitis were enrolled, predominantly affecting the lower limb (75%). Cellulitis features showed greatest improvement between enrolment and day 3. Clinical improvement continued gradually at days 7 and 14 with persistent skin erythema (41%) and swelling (37%) at day 14. Skin warmth was the feature most likely to be resolved at each time point. There was a discrepancy in clinician and patient assessment of cellulitis cure at day 14 (85.8% vs. 52.8% cured).ConclusionsA clinical response of cellulitis features can be expected at day 3 with ongoing slower improvement over time. Over one third of patients had erythema or swelling at day 14. Patients are less likely than clinicians to deem their cellulitis cured at day 14. Future research should include parallel patient and clinician evaluation of cellulitis to help develop clearer definitions of treatment failure and cure.© 2024 The Authors.
