REACT - REAl Care for AsThma A Disease Study to Identify Patients With Severe Uncontrolled Asthma Using EMR Pre-screening and AIRQ® Score Documentation Over 12 Months, Including Patient-documented OCS Use With the AIRQ®-Active Application

This is a multi-center, single-country, single-arm, prospective, disease study to collect real world data of patients with severe uncontrolled asthma in Germany.

Detailed Description

This observational disease study aims to improve the understanding of the real-world situation of patients with severe uncontrolled asthma, the influence of environmental factors on the risk of exacerbations as well as the patients' quality of life. The patients will provide self-reported information about their asthma control and medication use in a 12 months period after study enrollment. Additional patient information will be collected from existing electronical records (EMRs). Furthermore, patient- and provider-reported attitude towards healthcare and monitoring (measured through patient- and provider-reported experience measurements [PREMs]) will be collected to measure the level of satisfaction with the healthcare provision, digital and analog healthcare support programs, and the preferences in monitoring tools. The information will be collected either digitally with an application or analogically with paper-based questionnaires.

Study Population

The study population is composed of severe asthma patients within GINA/NVL (Global Initiative for Asthma/ Nationale Versorgungsleitlinie) steps 4 or 5 with uncontrolled disease (including patients on biologics but without any prescribed oral corticosteroids).

Description

Inclusion Criteria:

  • ≥18 years of age at the time of consent
  • Therapy within GINA/NVL steps 4 or 5 and uncontrolled disease in the previous 12 months as per the healthcare provider's assessment
  • Willing and able to provide written informed consent indicating that they understand the purpose and procedures required for the study and are willing to participate
  • Able to read, understand, and speak German sufficiently to complete all the questionnaires

Exclusion Criteria:

  • According to the assessment of the study physician: cognitive impairment, psychiatric diseases, severe hearing or vision impairment, insufficient knowledge of the German language, if these factors could influence the ability to provide written consent and correct completion and assessment of the questionnaires.
  • Current participation in an observational study that might, in the investigator's opinion, influence the assessment for the current study, or participation in a randomized clinical trial in the last 30 days.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of severe asthma patients with an Asthma Impairment and Risk Questionnaire (AIRQ®) score at baseline, and at 6 and 12 months post enrollment.
Time Frame: Up to 12 months

To ascertain the level of asthma control of the study population by the AIRQ® assessment.

The AIRQ® includes 10 questions (7 assessing symptom impairment and 3 assessing risk) concerning patient medication use, asthma symptoms, medical visits, and tests.

The AIRQ® can predict the risk for exacerbations and assess the quality of life of asthma patients.

AIRQ® score: well-controlled (0-1 points), not well-controlled (2-4 points) and very poorly controlled (≥5 points) asthma

Up to 12 months
