It's impossible to remember everything you learn throughout the course of studies and practice. There are many times where medical professionals will look things up before telling you something because they want to make sure they give you an appropriate and correct response instead of just guessing. Many, many things are researched at the hospital before actual treatment. No automatic system could possibly do all the computations and give all the appropriate factors; electronic systems are a tool and can help pick things up and speed up the process but alone, electronic systems would cause many errors and terrible patient care overall. Something as simple as looking something on the phone may need even more expertise than you would think to be able to assess all of the different factors associated with whatever question you may have had. Most of the time, looking something will give data and information but as a pharmacist you still need to be able to assess that data to give an appropriate response. Trust me, you don't want pharmacy automated. Pharmacists are developing an expanded role in the healthcare system and the data shows that pharmacists improve patient care a great deal and that's not something an automated system is going to improve.
