Background: Emollients are a mainstay of treatment for dry skin conditions. In the UK, prescribers are usually expected to follow local National Health Service (NHS) formularies. A previous study in 2018 showed that the recommended emollients across England and Wales varied widely. Evidence has since emerged that bath additives provide no additional clinical benefit in eczema.
Aim: To compare emollient formularies and guidelines in England.
Methods: Clinical Commissioning Group (CCG) formularies and guidelines were identified in April-May 2021, compiled and then analysed descriptively.
Results: In total, 105 CCGs, 72 emollient formularies and 47 emollient prescribing guidelines were identified. There were internal inconsistencies between formularies and their accompanying guidelines in 19% of cases. The majority (68%) of formularies/guidelines were organized using a ranking system. In total, 126 different leave-on emollients were named. Creams and ointments were universally available and were the most recommended first-line types. Cost was more likely than patient choice to be recommended as a criterion for selecting which emollient to prescribe. Aqueous cream was the leave-on emollient most commonly not recommended. Nearly three-quarters (74%) of formularies stated that bath additives should not be prescribed.
Conclusion: All CCGs in England have an emollient formulary/guideline, but there is still great variability between them in their recommendations. Although the number of formularies/guidelines has reduced since 2017, there has been an increase in the total number of unique recommended leave-on emollients. Most CCGs are no longer recommending bath emollients for eczema.
