Reported penicillin allergies hike inpatient costs

 

Key clinical point: Inpatient costs were $1,145 – $4,254 higher for those reporting penicillin allergy.

Major finding: Though most studies addressed inpatient admissions, outpatient costs were also significantly higher.

Study details: Systematic review and meta-analysis of 30 articles addressing reported penicillin allergy.

Disclosures: The study was sponsored by ALK.

FROM JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY: IN PRACTICE

Total inpatient costs for patients who report being allergic to penicillin are much higher than for those who don’t report an allergy, according to a recent systematic review and meta-analysis.

The review, which eventually included 30 articles, found that total inpatient costs ranged from an average $1,145-$4,254 higher per patient with a reported penicillin allergy compared to nonallergic patients, said T. Joseph Mattingly, PharmD, and his associates. Outpatient prescription costs were also estimated to be steeper, running $14-$93 higher per patient who reported a penicillin allergy.

Although 10%-20% of patients report a penicillin allergy, “[a] majority of patients who report PCN [penicillin] allergy are not truly allergic upon confirmatory testing,” Dr. Mattingly and his colleagues wrote.

This overreporting of penicillin allergies is a problem for the patient and the health care system because “reported antibiotic allergies have been associated with suboptimal antibiotic therapy, increased antimicrobial resistance, increased length of stay, increased antibiotic-related adverse events, increased rates of C. difficile infection, intensive care unit (ICU) admission, death, as well as increased treatment cost,” said Dr. Mattingly and his coauthors.
