    We aim to further the development of sleep medicine in Singapore by activities at several different levels:

    1. General Public
    Across the different sleep centres, we organize regular public outreach and sleep symposia to improve public awareness of various sleep disorders.

    2. Other Medical Professionals
    We also hold regular GP forums and sleep medicine courses to update colleagues, educate other specialties and professionals about the impact of sleep disorders and the need for a high index of suspicion in looking out for comorbid sleep conditions.

    3. Specialist Training
    Sleep medicine is a very special sub-specialty as the pathway to sleep training originates in several primary specialties. Our sleep fellowship training program accepts trainees who have completed their primary specialist training in the following specialties:

    • ENT
    • Respiratory medicine
    • Neurology
    • Dentistry
    • Psychiatry

    The training program for each of these entails common core modules as well as specialty-specific training requirements. Fellows will have the opportunity to work with experienced sleep specialists from Respiratory, ENT, Psychiatry, Dental and Psychiatry specialists across all SingHealth Duke-NUS cluster hospitals and medical centres. Fellows will also be expected to participate in research projects mentored and supervised by their primary fellowship director. For more details on the fellowship programme, please contact our Postgraduate Medical Institute (PGMI) at pgmi.fellowships@sgh.com.sg

    We organise Sleep Medicine Courses and Symposiums regularly to cater to the growing needs of specialists and sleep technologists wanting to manage sleep patients and improve their knowledge through continuing medical education.
