Development of the International Severe Asthma Registry (ISAR): A Modified Delphi Study

BACKGROUND: The lack of centralised data on severe asthma has resulted in a scarcity of information about the disease and its management. The development of a common data collection tool for the International Severe Asthma Registry (ISAR) will enable standardised data collection, subsequently enabling data interoperability.OBJECTIVES: To create a standardised list of variables for the first international registry for severe asthma via expert consensus.METHODS: A modified Delphi process was used to reach consensus on a minimum set of variables to capture in ISAR: the core variables. The Delphi panel brought together 27 international experts in the field of severe asthma research. The process…

Disease control and treatment pathways of asthma patients after initiating ICS/LABA

Introduction: GINA guidelines recommend medium dose (MED) and high dose (HD) ICS/LABA as the preferred controller for step 4 asthma patients and clinicians should consider step up/down based on their patients’ asthma control. Limited data is available on how step 4 patients respond to ICS/LABA and how they step up/down in clinical practice. Methods: We conducted a retrospective cohort study using UK Clinical Practice Research Datalink to assess control status of asthma patients in one year after initiating a MED or HD ICS/LABA between 2007 and 2015, and examined their treatment pathways within one year after the treatment initiation. Results: 29,229 and 16, 575 patients initiated MED and HD…

Eosinophilic and Noneosinophilic Asthma

Background Phenotypic characteristics of patients with eosinophilic and noneosinophilic asthma are not well characterized in global, real-life severe asthma cohorts. Research Question What is the prevalence of eosinophilic and noneosinophilic phenotypes in the population with severe asthma, and can these phenotypes be differentiated by clinical and biomarker variables? Study Design and Methods This was an historical registry study. Adult patients with severe asthma and available blood eosinophil count (BEC) from 11 countries enrolled in the International Severe Asthma Registry (January 1, 2015-September 30, 2019) were categorized according to likelihood of eosinophilic phenotype using a pre…

One-year follow up of asthmatic patients newly initiated on treatment with medium- or high-dose inhaled corticosteroid-long-acting β2-agonist in UK primary care settings

Abstract Introduction Global Initiative for Asthma (GINA) recommends medium- or high-dose inhaled corticosteroid-long-acting β2-agonist (ICS-LABA) as preferred treatments for patients with moderate-to-severe asthma. Limited data is available on how step 4/5 patients respond to ICS-LABA and how they step up/down in clinical practice. Methods This retrospective cohort study assessed the characteristics, control status, treatment pathways, and healthcare resource utilization in patients with asthma during one year after initiating medium- or high-dose ICS-LABA. Data from the United Kingdom Clinical Practice Research Datalink were analysed between January 01, 2006 and February 28, 2016. Results…
