Abstract
BACKGROUND: Skin and soft tissue infections (SSTIs) are a common cause of consultation, and complicated cases require hospitalization. We describe factors that are related to readmission and/or mortality of hospitalized patients diagnosed with SSTIs.
METHODS: Retrospective review of hospital-admitted patients with a diagnosis of cellulitis, abscess, hidradenitis, fasciitis, and Fournier's gangrene. Cases from January 2002 to October 2015 were extracted from the diagnostic codification database of the Archives and Clinical Documentation Department.
FINDINGS: We studied 1,482 episodes of hospitalized patients diagnosed with SSTIs. There were 187 (12.3%) readmissions, the most frequent diagnosis was cellulitis (72.7%), and the most commonly isolated microorganism was Staphylococcus aureus (25; 30.1%). Factors associated with readmissions were healthcare-related infections (P = 0.002), prior antibiotic therapy (P < 0.001), ischemic heart disease (P = 0.01), chronic liver disease (P = 0.001), and diabetes mellitus (DM) (P = 0.006). The number of patients who died as a result of an infection was 34 (2.2%) and, in these patients, the most common diagnosis was also cellulitis (79.4%), which in 52.9% (P = 0.001) was community acquired. DM (P = 0.01), heart failure (P = 0.001), and chronic liver disease (P = 0.003) were the most frequent comorbidities. This group presented more complications (P < 0.005) such as endocarditis (P < 0.005), amputation (P = 0.018), severe sepsis (P < 0.005), and septic shock (P < 0.001).
CONCLUSIONS: Readmitted patients had healthcare-related S. aureus infection, had received prior antibiotic therapy, and presented comorbid conditions such as ischemic heart disease, peripheral vascular disease, chronic liver disease, or DM. Comorbidities such as advanced age, DM, heart failure, and chronic liver disease were associated with complications and higher infection-related mortality.
