Background

Infections associated with central venous catheters (CVCs) are associated with considerable morbidity and mortality.

Methods

We conducted a survey to evaluate the theoretical knowledge and practices of intensive care unit doctors and nursing staff regarding CVC-related infections.

Results

A questionnaire was distributed to 345 doctors and nurses. The response rate was 71.6 % . Of the responders, 84.9 % worked in public hospitals, 40 % had been trained in CVC-related infection issues, and 27 % were familiar with the relevant Centers of Disease Control and Prevention guidelines. The mean percentage of correct answers (¡À standard deviation) on the 3 parts of the questionnaire were 42.9 % ¡À 16.2 % , 86.9 % ¡À 9.5 % , and 85.4 % ¡À 7.2 % . In the subset of questions referring to procedures that were doctors' exclusive responsibility, 13.6 % of the doctors answered all questions correctly. Age >37 years, awareness of relevant official guidelines, working in a private hospital, and being a doctor were identified as independent variables associated with high scores in knowledge regarding the prevention of CVC-related infections. Female sex and training in infection prevention were associated with higher scores on the part evaluating adherence to specific practices regarding CVC insertion, whereas being a nurse was associated with higher scores on the part evaluating CVC maintenance.

Conclusion

Our findings suggest that there is a need for increased theoretical knowledge and improvement in practices regarding CVC care. Educational programs directed at doctors and nurses working in intensive care units may aid this effort.
