ACP Hospitalist: â€œAbout 10% of patients in the United States report a penicillin allergy, but most of these patients are not currently allergic, meaning that they could safely take drugs in the beta-lactam class. â€œThe vast majority of patients who think they have penicillin allergies actually don’t when they undergo penicillin allergy skin testing,â€ said Emily Heil, PharmD, of the University of Maryland School of Pharmacy in Baltimore…. In fact, 96% of patients at one acute care facility who self-reported penicillin allergy had a negative skin test in a recent study by Dr. Heil and colleagues.â€
I wrote about the problems surrounding patient allergies in the medical record several years ago. One would think that things have improved over time. Not even close. The proliferation of Electronic Health Records (EHRs) has only made things worse. The inaccuracy and incomplete nature of drug allergy information located in EHRs is causing more problems than ever before.
It might surprise you â€“ or perhaps not – to find out that most patients donâ€™t know whether or not theyâ€™re allergic to a medication, much less what the details are surrounding the allergy. Many perceived allergic reactions can be classified as an adverse reaction, intolerance, or simply an expected side effect.
Many of the allergies I see recorded in EHRs could easily be classified as intolerance, which in my mind means they shouldnâ€™t be listed as an allergy. Having codeine listed as an allergy in the EHR because it causes GI upset is wrong. GI upset is not an allergy. GI upset to codeine does not preclude a patient from using any number of opioid analgesics. However, that little entry in the EHR will follow that patient around until the end of time, repeatedly rearing its ugly head whenever an opioid analgesic is prescribed. Each time a provider enters an order for an opioid analgesic, or a pharmacist verifies that order, or a nurse administers that order, they will have to contend with an allergy alert. The alert will fire, the provider will acknowledge it, quickly realize that itâ€™s not really an allergy, and truck on. Not only does the alert provide worthless information with no value to the provider, it contributes to alert fatigue, which we all know is a very real and dangerous thing in todayâ€™s EHR-driven healthcare world.
Allowing poorly defined allergy information to appear, and remain, in the EHR should not be allowed. Facilities that allow it should be reprimanded. Providers that enter it should be educated. Improving the quality of allergy information found in EHRs benefits everyone. It should be a priority.
According to the ACP Hospital article cited above, accurate allergy information can lead to optimized therapy, decreased use of broad-spectrum antibiotics, and decreased costs. Is there anyone in healthcare that doesnâ€™t want all of that?
Hereâ€™s the thing: itâ€™s such a simple thing. Collecting better allergy information is so easy that it makes my brain hurt. Itâ€™s low-hanging fruit that often gets ignored. It requires no special education, training, or skill. No technology required. It cost nothing. This is one of those rare instances when a little common sense goes a long way.
