I was just wondering how many of you have ever read the instructions for your TV changer, one of those hand-held devices?
Clinical practice guidelines are worse than that. The point is that converting these things into tools that can be used at point of care requires that an effort be taken to do so. You need people who understand what's happening at the clinical setting, and they reorganize the information so it makes sense from the doctor or prescriber/patient interaction point. It takes a concerted effort to do those things and that's why resources are required for it.
I'll also point out that pharmaceutical companies use academic detailing because it works. Academic detailing is an excellent way to work with any prescriber to help them use the best practices in their clinical practice setting. But these things require resources, leadership, and an intent to make the entire system work better.
