The incidence of prosthetic joint infection is increasing as the use of mechanical joint replacement increases. The treatment approach to prosthetic joint infection is based on different clinical situations such as a patient's comorbidities, epidemic microbiology data, and surgical procedures. The aim of our study was to understand clinical characteristics of prosthetic joint infection, the microbiology of the prosthetic joint infection, and the outcomes of different treatment strategies during 2006-2011. Methods: We retrospectively collected cases of prosthetic joint infection in the National Taiwan University Hospital between January 1, 2006 and December 31, 2011. The patients' characteristics, microbiology, outcomes, and factors associated with treatment success were recorded. Results: One hundred and forty-four patients were identified as having PJI. Of these, 92 patients were entered into per-protocol analysis. Staphylococcus aureus was the most common causative organism (29.9%), followed by coagulase-negative Staphylococci (16.7%), and Enterococci (9.7%). The overall treatment success rate was 50%. Patients who received a two-stage revision had a better outcome, compared to patients who underwent other types of surgeries (70% vs. 32.7%, respectively; p<0.001). In multivariate analysis, the two-stage revision was significantly associated with treatment success (odds ratio=3.923, 95% confidence interval=1.53-10.04). Conclusion: Our study demonstrates that Staphylococcus aureus was the most common causative organisms in PJI. Performing two-stage revisions was significantly associated with a better outcome. ? 2013 .[SDGs]SDG3Acinetobacter baumannii; Aeromonas sorbia; aged; Article; demography; Enterobacter cloacae; Escherichia coli; female; human; joint prosthesis; Klebsiella pneumoniae; major clinical study; male; methicillin resistant Staphylococcus aureus; methicillin susceptible Staphylococcus aureus; Mycobacterium tuberculosis; nonhuman; outcome assessment; prosthesis infection; Pseudomonas aereginosa; recurrent infection; retrospective study; Samonella choleraesuis; Serrratia marcescens; Staphylococcus aureus; Streptococcus gordonii; Taiwan; treatment failure; bacterium; classification; isolation and purification; microbiology; middle aged; osteoarthritis; pathology; Prosthesis-Related Infections; treatment outcome; university hospital; very elderly; Aged; Aged, 80 and over; Bacteria; Female; Hospitals, University; Humans; Male; Middle Aged; Osteoarthritis; Prosthesis-Related Infections; Retrospective Studies; Taiwan; Treatment Outcomejournal article10.1016/j.jmii.2013.08.00724064293
