Improving Patient Safety by Reducing Alert Fatigue

When a team at St. Jude changed its system for drug interaction warnings, doctors had less alert fatigue and were less likely to override important alerts.

Drug interactions are a serious hazard in hospitals and in the community. If patients receive prescriptions for incompatible medications, they can experience severe side effects that may even be life threatening. Electronic medical records are intended to warn prescribers and pharmacists about potentially dangerous interactions, but many do so indiscriminately. The result is something called alert fatigue.

Why Is Alert Fatigue Dangerous?

Think of it a bit like the boy who cried wolf. After the villagers came running to help him twice when there was no wolf, they didn’t pay attention to his next alert. So the wolf ate his sheep. When clinicians receive too many warnings, they may not pay attention to really important drug interactions that can cause patients serious harm.

Changing the Alert System to Reduce Alert Fatigue:

A team at St. Jude Children’s Research Hospital reviewed their alert system (Daniels et al, Pediatrics, Feb. 2019). They removed unnecessary alerts and provided additional information on the most important drug interactions. After they finished, they tracked clinicians’ reactions. Alert overrides dropped by 40 percent. One important change linked alerts to the patient’s laboratory data, making them much more targeted and less likely to result in alert fatigue.

The overhaul to the system made a significant impact. There were 40 percent fewer drug-drug interaction alerts cropping up for clinicians. Attending physicians actually had up to 82 percent fewer warnings about drug interactions. The changes in the system did result in two “patient safety events” during the study period. We don’t know whether those events resulted in patient harm, nor how many such events occurred during a similar time frame before the changes were undertaken.

The authors conclude:

“Our quality improvement effort refined 47% of all DDI alerts that were firing during historical analysis, significantly reduced the number of DDI alerts in a 54-week period, and established a model for sustained alert refinements.”

I agree with that that statement. Let your medicine be your food and your food be your medicine. Moderate exercise be as stress-free as possible. Most of all pray and ask God for help

To me it speaks volumes about the over-medicating of the population when literally thousands of potential harmful interactions are flagged. How in the world did people survive when there were no drugs. I have noted in reading death dates for many historical figures that surprising numbers reached their 70s and 80s as long ago as the 300’s with no statins, ppis, immune modifiers etc. etc. I am concerned how little emphasis is placed on nutrition and lifestyle and how much time, energy and money is dedicated to convincing everyone that taking (hopefully expensive) prescriptions will make them healthy. NOT!!!
