This pocket book succinctly describes 152 errors commonly made in obstetrics and gynecology in all clinical settings and gives practical, easy-to-remember tips for avoiding these errors. Easy to read during a short rotation, the book identifies all the key pitfalls in data gathering, interpretation, and clinical decision making.Each error is described in a short, clinically relevant vignette, followed by a list of things that should always or never be done in that context and tips on how to avoid or ameliorate problems. Coverage includes all areas in obstetrics and gynecology that are tested on certification and recertification exams. Jim . Demmel. EECS & Math Departments. UC Berkeley. Why avoid communication? . Communication = moving data. Between level of memory hierarchy. Between processors over a network. Running time of an algorithm is sum of 3 terms:.
