METHODS: Two questionnaires were devised to evaluate residents’ knowledge about obtaining intraosseous access. These included basic questions about appropriate site, apparatus, indications, contraindications and technique for IO placement. A two hour workshop was arranged with the help of critical care faculty at a university affiliated community based internal medicine residency program. 11 residents took part in the workshop. All participants filled out a pre workshop questionnaires. The participants also placed IO access in mannequins before the workshop and their performance was timed. This was followed by a didactic session that included evidence based information about IO access. Participants were also informed about appropriate apparatus, landmarks, techniques etc. Common misconceptions about the severity of pain, risk of infection and difficulty in performing IO line were also addressed. We also included a video aid for demonstrating administration of IO access. After the workshop all participants were timed again as they repeated the placement of IO access on mannequins. A different questionnaire that tested similar knowledge base was filled out by all participants after the workshop.
