Study description

Clinical guidelines for the management of obstructive lung diseases recommend a stepwise approach for treatment of asthma and COPD, but there is increasing realisation that a more personalised approach targeting “treatable traits” may be effective in achieving better control of these heterogeneous diseases. The Dutch asthma/COPD service (AC-service) supports general practitioners by diagnosing and monitoring patients with obstructive lung disease in a standardised way. Data collected within this framework offer a unique opportunity to quantify the frequency and stability of treatable traits among patients with obstructive lung disease.

Objectives:
A. To estimate the prevalence of eight treatable traits and the amount of overlap between these traits in patients with obstructive lung disease in Dutch general practice
B. To study the stability of treatable traits and the effect of management advice on changes in traits and health status in patients with obstructive lung disease who were assessed at a follow-up visit in Dutch general practice

Study design: A database study will be performed using data collected for the Asthma/COPD (AC)-service from patients with obstructive lung disease between 2007 and 2022. The presence (or absence) of eight treatable traits will be assessed at the patient’s first attendance to the AC-service. The stability of treatable traits and the effect of management advice on this and on health status will be assessed in patients who were followed-up by the service.

Study population: Patients attending the AC-service who were ≥18 years of age at the first AC-service attendance with a (working) diagnosis of asthma, COPD or Asthma-COPD overlap (ACO).

Analyses will be performed in:
1. The total study population of patients with a (working) diagnosis of asthma, COPD or Asthma-COPD overlap (ACO).
2. (Mutual exclusive) subpopulations of patients with a (working) diagnosis of: a) Asthma b) COPD c) Asthma-COPD overlap (ACO)
