Healthcare sector

But what about the healthcare sector?  In your area (or anticipated area) of professional practice/expertise… where do you access information that guides and drives your practice? If you are not working in healthcare –  Where do you get the information that informs your current job? What databases or sources do you use frequently?
What tools do you use? How much do you rely on your tablet or Smart Phone? Is it safe to use cell phones in hospitals?
