Projects & Publications

TARIPH’s initial research programme focuses on three inter-related thematic areas. The flagship project addresses our population, while the secondary projects focus on patients and healthy people. TARIPH projects will generate evidence on the presentation, course and consequence of respiratory illness in our patients and the population at large, work that will benefit Singaporeans with respiratory diseases and the maintenance of lung health.

Flagship project​​​​

  • Phenotypes of respiratory disease: A translational approach and analysis of service impact

    This project focuses on delineating clinical, mechanistic, behavioural and cultural differences across a range of chronic inflammatory respiratory disease states in Singapore including asthma, COPD, bronchiectasis, allergic rhinitis and allergy to better understand important clinically relevant and academic questions in primary, secondary and tertiary care settings.
Secondary projects​​​​​​​

  • United airways care in the community

    The united airways concept recognises that upper and lower airway diseases often coexist, but this relationship and the resultant multi-morbidity is not readily recognised. Hence, this project aims to establish the prevalence of asthma and rhinitis amongst patients cared for in the community (general practices and polyclinics), the interventions that will be needed to improve management, and the feasibility of allergy testing in the primary care setting.
  • Healthy lungs for our workforce: Occupational associated respiratory consequences

    This study aims to assess lung health in healthy individuals across a range of occupational and community settings that expose sub-populations to potential airway insults. The effect of lifestyle factors will also be assessed with the intention of understanding how best to preserve lung health as our workforce ages.
