An algorithm to describe patterns of intermittent oral corticosteroid use in the UK (n = 476,167) found that one-third of patients receiving intermittent oral corticosteroids for asthma only had short gaps (<90 days) between oral corticosteroid prescriptions sometime during follow-up. The increasing frequency pattern was more likely in patients with greater asthma severity and with more short-acting β2-agonist use at baseline. Our approach may provide a clinically relevant representation of intermittent oral corticosteroid use in asthma.
This project is based in part/wholly on data from the Optimum Patient Care Research Database (opcrd.co.uk) obtained under licence from Optimum Patient Care Limited and its execution is approved by recognized experts affiliated to the Respiratory Effectiveness Group.
