OpenAnesthesia, founded by Dr. Robert Thiele and Dr. Ed Nemergut, debuted in July 2009 with the broad goal of advancing graduate medical education in anesthesia. Since its inception as an experimental project, OpenAnesthesia has grown to be a comprehensive resource for anesthesiology residents, nurse anesthetists, and physician anesthesiologists. The site now sees more than 250,000 page views per month and is a ubiquitous tool for education with a large, international community of members.
The latest addition to the OpenAnesthesia portfolio of learning tools is the OA Self-Study and Keywords App, available on iTunes (v. 3.0) and Google Play (v. 1.0). This app is free and offers all the 2008-2014 ABA keywords along with 50 free self-study questions, including complete answers and links to other articles on OpenAnesthesia and PubMed. Additional questions can be purchased for a small fee, which goes to support the educational mission of OpenAnesthesia.
