Mixed-methods evaluation of an enhanced asthma biologics clinical pathway in the West Midlands UK.

Biologic treatments can alleviate severe asthma symptoms and reduce health service use. However, service capacity limits and low referral rates from primary care indicate unmet patient need. We report a mixed-methods evaluation of an enhanced severe asthma pathway implemented in Staffordshire and Stoke-on-Trent, UK which aimed to optimise primary care referrals through training/education, and increased capacity in specialist clinics.
