Skin infections in Europe: a retrospective study of incidence, patient characteristics and practice patterns.

OBJECTIVE

Acute bacterial skin and skin structure infections (ABSSSIs) are associated with considerable morbidity and a heavy healthcare burden. The primary objectives of this two-phase study were to determine the incidence of skin infections and ABSSSIs in hospitalized patients (Phase A), and to describe the characteristics and treatment of hospitalized patients with ABSSSIs (Phase B).

METHODS

This non-interventional, retrospective study was based on data collected from adult patients hospitalized for skin infections in six European countries (Czech Republic, Greece, Italy, Portugal, Russia and Spain) between January 2014 and June 2016.

RESULTS

In Phase A, the total hospital incidence of skin infections and ABSSSIs was 2.4 and 1.8 per 1000 patient-days, respectively. Overall, 73.6% of 50,469 hospitalizations for skin infections were for ABSSSIs. Among the 750 patients with ABSSSIs included in Phase B, Gram-positive bacteria were isolated in 24.9%, most commonly methicillin-susceptible Staphylococcus aureus (11.5%). Empirical therapy was administered to 98.1% of patients, most often with a penicillin, with or without a β-lactamase inhibitor (42.1%). Complete cure was achieved in 46.5% and 34.5% of patients after initial treatment and treatment modification, respectively. Overall, 22.7% of patients had at least one additional ABSSSI-related hospitalization, 47.1% of patients visited the emergency room, 19.3% of patients visited primary care clinics, and 34.8% of patients visited a specialist.

CONCLUSION

Treatment of ABSSSIs in Europe is associated with a heavy healthcare burden, highlighting the need for optimized management strategies that may reduce healthcare utilization.
