Screen Shot 2013-11-17 at 3.36.05 PMFor the ALiEM – Annals of EM global journal club on the article “Emergency Department Computed Tomography Utilization in the United States and Canada”, discuss question number 2 on the topic of estimation on CT counts:

Do you think the National Hospital Ambulatory Medical Care Survey (NHAMCS) method is likely to overcount or undercount CTs? What about the method used for calculating use in Ontario? Would these biases likely make the authors’ estimate of the overall difference between these countries too large or too small? Defend your answer.
