Hospitals Dispensing Meds Safely via Barcodes

Roaming the VOA site after my previous post, I learned that some US hospitals are combating "fatal medication errors" by linking dosage and dispensing with barcode scanning.

A bit unnerving to learn, as well, that as many as 7,000 hospital patients die each year due to errors in dispensing meds. How many lawsuits did it take to generate those figures?
