A quasi experimental study with one group pretest and posttest without control group design was undertaken in Vinayaka Missions Hospital, Salem to assess the effectiveness of video assisted teaching module regarding central venous catheter related blood steam infections and its prevention on knowledge of staff nurses working in ICU. Data was collected from 50 staff nurses selected by purposive sampling technique using closed ended questionnaire from 20.09.10 to 02.10.10.

Overall pretest mean score was 19.5±4.71 (48%) whereas it was 29.62±3.21 (72%) in posttest revealing 24% enhancement of knowledge score. Area wise highest post test mean score was 81% which was obtained for the area of "The type of central venous associated infections" whereas the lowest post test mean score was 68% of the total score obtained for the area of "Precaution while taking care of patients with CVC".
