Through a system of epidemiological surveillance of infections is studied in our hospital the infectionincidence in hip and knee replacement between 2007 and 2012. The results are compared with otherSpanish and European surveillance systems (HELICS® and Inclimecc® Program). In our hospital have taken place a total of 3155 hip and knee replacements (hip and knee replacements because of osteoarthritis and, in case of hip replacements, also for subcapital fractures) reporting a total of 66 infections, with infection rate of 2.09.The predisposing factors studied were: diabetes mellitus, obesity, neoplasia, renal failure, rheumatoid arthritis and taking steroids, so the first two factors were present in most cases of infection (32 % and 26 % respectively).It has also been seen that longer surgeries (over 110 minutes) show a higher incidence of infection. In terms of microbiology, Coagulase-negative Staphylococcus, Acinetobacter baumannii and Staph. Epidermidis were the most common until 2009 (4/36 CNS, 4/36 Ac. Baumanii, 3/36 Staph.Epidermidis) and in 2010 had more presence Enteroc. Faecalis (3/12) and Eschericlia coli (3/12), although Acinet. Baumanii (4/12) was still the most common.In 2012 should also be pointed Pseudomonas aeuginosa (2/8). Infection rates in our hospital are below levels recommended by the Spanish Society of Preventive Medicine and Public Health levels and also lower than the standard infection rate of HELICS® program in Spain.
