Asthma severity: the patient’s point of view

Objective: Initiated by the Severe Asthma Network Italy (SANI), this study aims to explore asthma patients' perceptions of disease severity, differentiating between mild and severe asthma. The objective is to identify factors influencing tailored treatment strategies for varying disease severities and to provide insights into asthma care in Italy. Methods: Conducted between November 2020 and January 2021, a survey using Computer-Assisted Personal Interviewing (CAPI) collected data from 308 Italian adults, representing the population. A 25 item multiple choice questionnaire covered asthma diagnosis, symptoms, treatment approaches, associated conditions, and quality of life. Results: Among participants, 83.8% reported having mild asthma, while 16.2% had severe asthma. Severe asthma patients had longer disease durations, more severe symptoms, frequent exacerbations, and higher hospital/ER visits. Although treatment adherence and symptom profiles generally aligned with international guidelines for self reported severe asthma, 22% of self identified mild asthmatics experienced severe respiratory symptoms. Oral corticosteroid (OCS) use was observed in 50% of severe cases and 22% of mild cases. Adherence was higher in severe asthma patients (76%) versus mild asthma patients (28%). Both groups experienced comorbidities, with 96% of severe asthmatics and 72% of mild asthmatics reporting impaired quality of life. Conclusion: This study highlights the disparity between clinical categorization and patient perceptions of asthma severity. The prevalence of self reported severe asthma exceeds literature data. The burden of mild asthma remains significant, with treatment approaches not fully aligned, particularly regarding disproportionate OCS use. Addressing this gap requires enhancing patient education, improving diagnostic practices, and promoting adherence.
