Nursing not only has a stake in this issue, but plays a valuable role in resolving it.
Physician orders initiate clinical interventions, which then produce outcomes.
So if we can proactively influence physician orders, we can influence patient outcomes. Information systems have a ways to go, but they aren't the root of the problem. To be effective, physician order entry systems must anticipate common medical mistakes and communicate with existing systems. And if a system is more difficult to use than paper and pen, physicians won't use it. But it hasn't been perfected to the point of widespread adoption.
