Burden of the Atopic March in Ontario

Client: IQVIA Solutions Canada Inc.

Project ID: P2019-058 / 2020 0970 172 000

Research Question/Objectives: The development of atopic dermatitis as an infant and the subsequent progression of allergic rhinitis and asthma in later childhood is known as the atopic march. Research into each of these conditions has shown an impact to the patients and the healthcare system. However, to date, limited research has been performed on understanding the prevalence and the cost to the healthcare system to treat moderate to severe patients. The objective of the current research project is to determine the co-morbidity of patients with asthma, atopic dermatitis and nasal polyps.

Research objectives:

  • Determine the demographic characteristics and the co-morbidity overlap of patients with asthma, atopic dermatitis, and nasal polyps.
  • Measure the total direct healthcare costs of moderate-to-severe asthma, atopic dermatitis, and nasal polyps patients.
  • Identify the prevalence and recurrence rates of nasal polyp surgeries.
