Clinical, diagnostic, and therapeutic features of patients admitted to acute care hospitals with trunk compared to lower limb cellulitis.

The objective of this study is to report the clinical course and risk factors of trunk cellulitis, to identify diagnostic and therapeutic approaches, and compare them to patients with lower limb cellulitis. Medical records of adult patients with trunk cellulitis were reviewed and compared to an equal number of randomly selected patients with lower limb cellulitis. Demographic, clinical, and laboratory data were collected and analyzed using binary univariate and multivariate logistic regression analyses. Primary outcome was surgical drainage. Secondary outcomes were use of imaging studies, length of stay, readmission within 30 days, and 30-day mortality. During the study period, 74 patients were diagnosed with trunk cellulitis. Compared to patients with lower limb cellulitis, there are more women (57 vs. 39%, p = 0.032) and they are younger (mean age 59.7 vs. 68.4 years, p = 0.005). The only co-morbidity found as a significant risk factor for trunk cellulitis is malignancy (p = 0.017). These variables remain independent risk factors for trunk cellulitis after multivariate regression analysis. There is a trend toward more surgical interventions in the study group [6 (8%) patients vs. 1 (1%) with leg cellulitis, p = 0.116], and a longer hospital stay (5.8 days in the study group vs. 4.3 days in the control group, p = 0.025). Laboratory data are similar in both groups. There are risk factors for trunk cellulitis compared to lower limb cellulitis. However, diagnostic and therapeutic approaches are similar, except for a trend for more surgical interventions.
