Children's Services
Asthma is a severe chronic condition with significant morbidity, mortality and high economic burden. It is estimated that 140,000 individuals in Singapore have asthma.
The Singapore National Asthma Programme (SNAP) in KKH was launched in August 2001. All high-risk asthma patients here are identified by the clinicians or asthma resource nurses and are followed-up closely by the National Asthma Shared Cared Clinic in KKH.
The primary goal of SNAP is to reduce the frequency of severe asthma attacks and improve the quality of life of patients with asthma.
Satisfactory asthma control improved from 9,1% with the 1st visit to 73% on the 6th visit. Return rate to the Children's Emergency reduced from 66% on 1st visit to 11% on the 6th visit.

- Recruitment of high-risk asthma patient from August 2001 to January 2010, with a total of 3462 patients.
