The CIA Score: a Learner's Tool

The goal of this project is to use a previously described scoring system - the CIA system - as a teaching tool to help learners assess the bleeding risk of peripheral nerve blocks. We will teach the CIA system to residents, then they will complete a survey in which they apply the system to various peripheral nerve blocks. We hypothesize that the CIA system will allow learners to reach the same consensus about bleeding risk as expert opinions.

Prior survey of Stanford and Palo Alto VA regional anesthesiologists showed diverging assessments of whether various blocks are considered superficial or deep. Investigators hope to have a simple systematic approach to scoring regional anesthesia procedures which can be used as a basis for discussion and comparison of regional expert's opinions. A scoring system using three categories of consideration to classify any regional procedure is proposed. The following three categories, Critical, Intervention, and Assess (CIA) can be used to analyze any procedure to determine bleeding risk. A score of 0 or 1, was given to each parameter depending on whether it was absent or present. A total score can be range from 0 to 3. From this, the risk can be categorized based on the total score as low-risk (0), intermediate-risk (1) or high-risk (2 or 3).
