resist the effects of current antibiotics.<\/p>\n<p>\u201cThe global challenge of antibiotic resistance is causing people to die of common infections, so it is vital to find ways to improve how antibiotics are used.<\/p>\n<p>\u201cAssessing people with penicillin allergy labels is one way we can achieve this.\u201d<\/p>\n<p>Patients who had the allergy check also had fewer antibiotics overall, the study suggests.<\/p>\n<p>As part of the study, researchers analysed the cost-effectiveness of allergy testing based on the NHS model.<\/p>\n<p>They said that although results may vary in different countries, the study observed \u201ctendency towards reducing consultations, days in hospital, and emergency admissions\u201d which \u201csuggest that the penicillin allergy assessment pathway is cost-effective in the short run and increasingly likely to be so over longer follow-up periods\u201d.<\/p>\n<p>Researchers now suggest that \u201caccess to penicillin allergy assessment for patients should be widened\u201d.<\/p>\n<div class=\"sc-482ou5-2 hmmOgn sc-482ou5-3 image align-center\">\n<figure class=\"sc-1cbdeug-0 cXcwgU\">\n<div data-gallery-length=\"2\" class=\"sc-482ou5-0
