National asthma observational survey of severe asthmatics in Israel: the no-air study.

Background: Asthma is considered a global public health issue requiring a significant medical expenditure as a result of its high prevalence and the low rate of disease control.

Objective: This is the first nationwide survey of severe asthma patients carried out in Israel. In this study we aimed to assess health resources utilization, compliance with treatment and disease-control in a subgroup of patients with severe asthma in Israel.

Material And Method: One hundred and twenty-three patients with a diagnosis of asthma for more then one year, as well as a hospitalization during the last 12 months due to asthma exacerbation or maintenance systemic steroids therapy, were included in this non-interventional observational study.

Results: Asthma was uncontrolled in 43.9%, partly controlled in 50.4% and well controlled in only 5.7%. The majority of the patients (83%) were compliant with drug treatment.

Conclusion: The fact that 83% of the asthma patients included in this study were compliant with their asthma therapy was not manifested in asthma control. Therefore concrete tools are required for achieving and maintaining asthma control, especially in the treatment of the most severe asthmatic patients.
