P&T Community (pharmacy and therapeutics) has a story about the basic patient safety value proposition on smart pumps (pdf). This might be just the thing to help educate management (its only one page long) if you're looking to adopt smart pumps in your hospital.
Justifying smart pumps is the easy part - selecting the best solution for your hospital is another matter. The vendor selection criteria for smart pumps are different that the criterion for standalone IV pumps. Simply "upgrading" to your current vendor's smart pump could be a big mistake. The infrastructure of an end-to-end smart pump system (WLAN, servers, software, training) is expensive and most all of it would have to be replaced if you change pump vendors.
Like any medical device category that is early in its adoption of connectivity, smart pump solutions are immature. Current features are just scratching the surface of infusion workflow automation, with most solutions providing little more than a check on manual pump configuration for a specific drug. The real patient safety win is the end-to-end automation of the infusion therapy process, starting with order entry, pharmacy fulfillment, administration and alarm notification. No vendor has this complete solution yet, but some are much closer than others.
