Patterns and trends in eczema management in UK primary care (2009-2018): a population-based cohort study.

BACKGROUND Despite the high disease burden of eczema, a contemporary overview of the patterns and trends in UK primary care healthcare utilisation and treatment is lacking. OBJECTIVE To quantify primary care consultations, specialist referrals, prescribing, and treatment escalation, in children and adults with eczema in England. METHODS A large primary care research database was used to examine healthcare and treatment utilisation in people with active eczema (n=411,931). Management trends and variations by age, sex, socioeconomic status, and ethnicity were described from 2009-2018 inclusive. RESULTS Primary care consultation rates increased from 87.8 (95% confidence interval [95%CI] 87.3-88.3) to 112.0 (95%CI 111.5-112.6) per 100 person-years over 2009 to 2018. Specialist referral rates also increased from 3.8 (95%CI 3.7-3.9) to 5.0 (95%CI 4.9-5.1). Consultation rates were highest in infants. Specialist referrals were greatest in the over 50s and lowest in people of lower socioeconomic status, despite the highest rates of primary care consultations. There were small changes in prescribing over time; emollients increased (prescribed to 48.5% of people with active eczema in 2009 compared to 51.4% in 2018) and topical corticosteroids decreased (57.3% to 52.0%). Prescribing disparities were observed, including less prescribing of potent and very potent topical corticosteroids in non-white ethnicities and people of lower socioeconomic status. Treatment escalation was more common with increasing age and in children of non-white ethnicity. CONCLUSION AND CLINICAL RELEVANCE The management of eczema varies by sociodemographic status in England, with lower rates of specialist referral in people from more deprived backgrounds. There are different patterns of healthcare utilisation, treatment, and treatment escalation in people of non-white ethnicity and of more deprived backgrounds.
