As EMRs and EHRs incorporate more and more functions, they are going to be giving more advice and warnings to their users. A very real concern among many developers of health informatics systems is "alert fatigue" -- the idea that too many irrelevant alerts will annoy users. And worse, that a flood of useless alerts will cause users to ignore all alerts and warnings, rendering the system's automated checks pointless.
The only way to limit alert fatigue is to be more intelligent about when alerts are shown, and to whom. The key problem is not "too many alerts" -- it's "too many irrelevant alerts". There are two strategies that can help with this.
1. Allow users to customize their own alerts
Each user of your system likely has their own login which is theirs alone. This means that savvy EHR vendors can make it possible for clinicians to customize their own alerts. When an alert is shown, they can select whether they want to see the alert again -- in effect, controlling the information they see by telling the system not to show them alerts they consider irrelevant.
2. Intelligently manage alerts by types of users and circumstances
Another strategy is for the system to do some of this work ahead of time. If an alert applies only to administration, the system would know to show the alert to the prescribing doctor or the compounding pharmacist -- but instead only to the administering nurse. Likewise, if an alert applies only to pregnant women, the system would know not to show it if the patient in question is a man. This strategy relies on knowing things about your users (e.g., what kind of cilnician they are) and the circumstances of the encounter to anticipate which alerts may be irrelevant.
The most successful EMRs will likely use a combination of both approaches. But the second strategy can help alleviate alert fatigue immediately -- your users don't have to manage their own preferences to see the benefits. However, it also relies on detailed drug interaction databases able to finely slice alerts for you. Lexicomp is one medication information vendor that is innovating in this arena, and creating complex filters for many of its alerts and warnings.
