In an article in Pediatrics Carroll and Christakis report that 35% of pediatricians use a PDA at work. So for that 35%, what do they actually do with them?   80% use it for a drug reference and 65% for scheduling but as this chart shows only 22% kept patient information on the PDA and few wrote scripts (8%) or used it for billing (4%). So, as I surmised in my earlier piece on PDA use, the tools are out there, but they are not integrated into the wider clinical workflow.  Integrating these tools which are entering via the "backdoor" into the overall clinical workplace IT strategy is the challenge for CIOs.
