ERS/EAACI statement on adherence to international adult asthma guidelines

Clinical practice guidelines based on the best available evidence, aim to standardize and optimize asthma diagnosis and management. Nevertheless, there are concerns that particularly between different groups of healthcare professionals (HCPs), adherence to guidelines is suboptimal. Further to these concerns, the aims of this ERS/EAACI Statement were (1) via an international online survey, to evaluate and compare the understanding of and adherence to international asthma guidelines by HCPs of different specialties, (2) via systematic reviews of the literature, to assess effectiveness of strategies focused at improving implementation of guideline-recommended interventions, and compare process and clinical outcomes in patients managed by Specialists (respiratory physicians or allergists) or Generalists (internists or general practitioners). The online survey identified discrepancies between HCPs of different specialties which may be due to poor dissemination or lack of knowledge of the guidelines but also a reflection of the adaptations HCPs working in different clinical settings make, based on their resources. The systematic reviews demonstrated that multifaceted quality improvement initiatives addressing multiple challenges to guidelines adherence, or the input from additional specialized HCPs are most effective in improving guidelines adherence. More data are needed to evaluate differences in process and clinical outcomes among patients managed by Generalists or Specialists. Our results reveal a need for guidelines to consider the heterogeneity of real-life settings for asthma management and tailor their recommendations accordingly. Continuous, multifaceted quality improvement processes are required to optimize and maintain guidelines adherence. Validated referral pathways for uncontrolled asthma or for uncertain diagnosis are needed
