I have worked with an orthopaedic surgeon (solo physician practice) for about 18 months. I currently see patients independently in the office for initial histories and physicals, pre-op visits, post-op visits, etc. The physician has asked me to expand into the OR. Initially, he said he could do "on the job training" for me and teach me what I needed to know. I currently have privileges at the hospital where he does all his inpatient surgeries. Eventually, I want to be able to function as the First Assist and be able to bill for my services. I also have a Medicare provider number. I am in the process of dialoguing with the director of periop services about additional training/credentialing that is needed. Does anyone have a feel for minimal training I need? I do not have previous OR experience but do have a bachelors and masters degree in nursing and am certified as a family nurse practitioner. I would appreciate any suggestions on resources to consult, etc. I have visited the AORN Web site and printed off the "Official Statement on RN First Assists."
