Expensive, some questions painfully dated

The app is well designed and has good functionality but is expensive. One would think with the premium price the ACCP would keep it up to date but some questions are clearly dated. For example, a question on whether or not to continue heparin prophylaxis for patients getting Xigris. Xigris was pulled from the market in 2011. At this price the questions should be more consistently state of the art. I purchased this as an adjunct to the hard copy book edition and clearly some of that material is duplicated here.
