Clinical characteristics affecting length of stay in patients with cellulitis.

BackgroundThis study aimed to profile the clinical characteristics of patients presenting to Middlemore Hospital with cellulitis in order to identify factors that are associated with an increased length of stay (LOS). MethodsRetrospective clinical data were collected for all patients aged 18 and above who were admitted with cellulitis to Middlemore Hospital General Surgical Department between 1 January and 31 March 2014. Comorbidities, laboratory results and medical conditions were included in the investigation. ResultsThe study included 201 patients. Significant factors associated with increased LOS include type 2 diabetes mellitus (P <0.012), obesity (P <0.001), raised C-reactive protein (P <0.0001), raised white cell count (P <0.0001), raised temperature (P <0.0001), septic shock (P <0.003), multiorgan failure (P <0.01), extended-spectrum beta-lactamases or methicillin-resistant Staphylococcus aureus colonization (P <0.04) and intensive care unit admission (P <0.0004). ConclusionThis single-centre, retrospective clinical study has identified several factors that are significantly associated with an increased LOS. These factors provide a basis for future studies that may facilitate identification and timely medical optimization of high-risk patients.
