Purpose:
Surveillance of preventable healthcare associated infections and feedback of the results to clinicians is central in the efforts to improve performance. We assessed Staphylococcus aureus healthcare associated bloodstream infection (HA-BSI) as an indicator of healthcare quality.
Patients And Method:
Between 2002 and 2012, we carried out a ten-year prospective bedside surveillance of S. aureus healthcare associated bacteraemia in a 940-bed university hospital using standard definitions.
Results:
Overall, 2784 HA-BSI were identified during the study period, among which 573 (18%) were due to S. aureus. Among these 573 S. aureus bacteraemias, 189 originated from intravascular catheters (32.8%) of which 84% (158/189) in patients outside intensive care units. The proportion of catheter related HA-BSI due to S. aureus was 56% (61/109) in PVC-related HA-BSI and 34% (103/301) in CVC-related HA-BSI. A sharp decrease of PVC-related HA-BSI from 20 to 7 per year was obtained during the same period.
Conclusion:
In our experience, S. aureus HA-BSI is a simple and useful indicator of catheter associated infections, and therefore of healthcare quality, especially in units not covered by other type of surveillance.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
