The document describes a "just-in-time refresher" program to improve infant lumbar puncture (LP) outcomes. The program involves brief 5-minute coached refreshers where residents practice their LP skills on a simulator before performing procedures on patients. The refreshers provide hands-on teaching and feedback to help residents polish their skills. They involve setting up a simulator, supervising the resident's performance, and using a form to rate their skills both before and after the simulator practice. The goal is to help residents perform independently and confidently in clinical settings.
