NICE has issued a warning for those people who incorrectly believe they are allergic to penicillin as such misconception may unnecessarily put them at an increased risk of developing MRSA or C difficile.
Nice has also urged the clinicians to ensure that only people with a true allergy to penicillin are documented as such. Incorrectly identifying people as allergic could also contribute to antimicrobial resistance, as these people are likely to instead be given broad-spectrum antibiotics.
Speciality Medical Dialogues has previously reported this issue based on research conducted in the UK and published in the BMJ in June 2018 that the patients allergic to penicillin are at increased risk for Clostridium difficile and methicillin-resistant Staphylococcus aureus (MRSA) infections mediated by the increased use of β lactam alternative antibiotics.
The warning comes in a new medicines evidence commentary (MEC) based on the above study.
Key Findings of the study:
- During 6 years’ follow-up, 70% of patients with penicillin allergy developed an MRSA infection.
- They are also around 25% more likely to develop C difficile, a bacteria that generally causes diarrhea.
- Among patients with penicillin allergy, the adjusted hazard ratio for MRSA was 1.69.
- The study highlights previous evidence that around 10% of the UK population has a penicillin allergy documented in their clinical notes, but that only around 5% of these people actually have a ‘true’ penicillin allergy.
The findings outline the need for healthcare staff to check that only bona fide penicillin allergies are recorded, in line with NICE recommendations on suspected allergy to Beta‑lactam antibiotics, which form part of NICE guideline ‘Drug allergy: diagnosis and management’.
