N2  -  Introduction. Blood culturing supports appropriate antibiotic therapy and contributes to refine surveillance of catheter related blood stream infections (CRBSIs). Clinical utility of blood cultures, however, could be conditioned by poor quality of collecting. A preliminary analysis into a hospital of Rome (IT) revealed a high frequency of contamination during pre-analytical phase, recalling the need to improve collection procedures, primarily in departments less compliant with local guidelines. Methods. A retrospective study (2002-10), estimating the mean rate of microorganisms considered as contaminant in positive blood cultures, identified three major outlier departments (i.e. with the highest values of non-compliance). A training course on microbiological collection and practical use of Laboratory Information System (for patient-requests)was planned. All nurses of the three departments were enrolled (n.47). The course was designed for small groups and consisted of exercises both on dummy and PC-workstation. Subsequently, an assessment of contamination rate was performed. Results. In 2002-10 the mean frequency of contaminants for three departments – calculated on a six-month basis- was 7.6%. In the 1st half of 2011 (which included the period of the training) the frequency was 5.1%. In the 2nd half of 2011, after the training, proportion of contaminated reduced to 3.0% (lower than the historical value; p<0.0001). Discussion. The educative intervention seemed to be effective. Follow-up study showed maintenance of good compliance one year after the course. In contrast, slight decrease of performance was observed after a further period of surveillance, suggesting the opportunity to repeat the course or implement a different strategy.
