Database of All Patients Who Have Undergone Pulmonary Function Testing at Singapore General Hospital
Database of All Patients Who Have Undergone Pulmonary Function Testing at Singapore General Hospital
The purpose of this study is to create a prospective database of all patients who have
 undergone pulmonary function testing from which the investigators can study the clinical
 phenotypes of various respiratory conditions. The investigators hope by understanding the
 differences in these myriad phenotypes to be able to provide individualized, patient-targeted
 therapy in the future.
Recent studies have shown that clinical phenotyping of patients with various respiratory
 conditions is important in the understanding of the disease process, clinical response to
 treatment, and prognosis. Pulmonary function testing is a very important aspect of clinical
 phenotyping in many respiratory conditions. Creating a database will enable us to study the
 various phenotypes within each respiratory condition. This will allow us to better understand
 each disease, with a view to provide personalized patient care targeted at their specific
 phenotype and hence better clinical outcomes.
Inclusion Criteria:

 1) All patients who have undergone pulmonary function testing at the Singapore General
 Hospital pulmonary function laboratory
