Cellulitis is among the most common infections leading to hospitalization, yet the optimal duration of therapy remains ill defined. Pragmatically, Dutch guidelines advise 10-14 days of antibiotics, which is the current standard of care. Recently it has been shown that antibiotic treatment for pneumonia and urinary tract infections can safely and significantly be shortened. Importantly, in an outpatient setting, treatment of uncomplicated cellulitis with 5 days of antibiotics was as effective as 10 days. We hypothesize that there is no difference in outcomes when patients hospitalized with cellulitis are treated with either a short-course (6 days) or standard-course (12 days) of antibiotics.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Cellulitis severity score subgroup analysis | Analysis to see if the height of the cellulitis severity score influences outcome, using a regression analysis with interaction term for severity score. | up to day 28 | |
Other | Diabetes mellitus subgroup analysis | Analysis to see if having diabetes mellitus influences outcome, using a regression analysis with interaction term for diabetes. | up to day 28 | |
Other | Per protocol analysis | Like main outcome, but the following will be included: (i) patients with treatment failure, who have received at least 24 hours of study medication, and (ii) patients with treatment success, who have received at least 80% of study medication. Treatment failure is defined as the persistence or progression of signs and symptoms of the acute process after randomization, or the inability to complete the study owing to adverse events. The response is deemed indeterminate when the patients (i) received less than 80% of the study drug for reasons other than treatment failure, (ii) acquired a concomitant infection outside of the skin requiring antibiotic treatment, (iii) were lost to follow-up, or (iv) died unrelated to the primary diagnosis. | up to 28 days | |
Other | Per protocol analysis of the "resolution without relapse" secondary outcome | Like secondary outcome, but the following will be included: (i) patients with treatment failure, who have received at least 24 hours of study medication, and (ii) patients with treatment success, who have received at least 80% of study medication. Cured is defined as above (under secondary outcome). Indeterminate is (i) receiving <80% of study drug for reasons other than unblinding/requiring new AB for cellulitis/being unable to continue due to adverse effects, (ii) acquired a concomitant infection outside of the skin requiring antibiotic treatment, (iii) were lost to follow-up, or (iv) died unrelated to the primary diagnosis. Patients who are not cured nor indeterminate are failures. | up to 28 days | |
Other | Sensitivity analyses of the "resolution without relapse" secondary outcome | Similar, but requiring further improvement of symptoms by either 1 or 2 points by day 28, instead of just stability of symptoms. | up to 28 days | |
Other | Adjustments for baseline covariates | Sensitivity analysis, adjusting the primary outcome for baseline covariates | up to day 28 | |
Primary | Part 1/2: Resolution... | Resolution of cellulitis at day 14, defined as disappearance of warmth and tenderness at the site of infection, with substantial improvement in erythema and edema | day 14 | |
Primary | Part 2/2: ...without relapse | No recurrence by day 28, defined as the need for additional antibiotic therapy for cellulitis | day 28 | |
Secondary | Resolution without relapse | Other operators used to define resolution at day 14 (no fever; reduction in combined erythema/edema/warmth/tenderness score of at least 2 points, or reach 0) and relapse at day 28 (no fever; stable or further improved combined score; no new antibiotics for cellulitis) | day 28 | |
Secondary | Recurrence at day 90 | Recurrence of cellulitis by day 90, defined as the need for additional antibiotic therapy for cellulitis | 90 days | |
Secondary | Objective speed of recovery | Improvement in cellulitis severity score (a 7 item scoring system, each with a score between 0-3; items are erythema, warmth, tenderness, edema, ulceration, drainage and fluctuance). Determined at day 1, day 2-3, day 5-6, day 14, and day 28 | Up to 90 days | |
Secondary | Health related Quality of Life | Using questionnaires Dutch SF-36 and EQ-5D at day 1, day 28, and day 90 | Up to 90 days | |
Secondary | Health care resource utilisation | Determined by total antibiotic use and effect on direct and indirect health-care associated costs, using modified versions of iMTA's Productivity Cost Questionnaire (iPCQ) and Medical Consumption Questionnaire (iMCQ). Measured at day 5-6, day 28 and day 90. | Up to 90 days | |
Secondary | Subjective speed of recovery | Visual Analog Scales (0-10) on pain and on swelling. Determined at day 1, day 2-3, day 5-6, day 14, day 28, and day 90 | Up to 90 days | |
Secondary | Additional antibiotic usage | Total usage of additional antibiotics for cellulitis between the end of treatment and day 90. | Up to 90 days | |
Secondary | Time to relapse | Time between end of treatment and the need for additional antibiotics for cellulitis | Up to 90 days |
