At Samitivej we understand that it isn’t always convenient to see a specialist during regular working hours. Our patients, and the family members who care for them, have responsibilities that demand their time. Furthermore, we know that illnesses and injuries do not confine themselves to a 9-to-5 schedule. As such, we have extended our working hours until 10:00 p.m. daily, an improvement we like to call Experts at Night. This means that you can count on our JCI-accredited care whenever it’s best for you.


Whether you’re a working mom whose child came down with a fever, a busy professional who needs a prescription renewed, or an elderly individual who has slipped on the stairs, we do our best to ensure that you receive appropriate care in a timely fashion. Our Experts at Night are available for scheduled and non-scheduled appointments, because we know it’s needed and most importantly because we care.

Samitivej’s Emergency department will continue to provide excellent care for all patient conditions around the clock. After 10 p.m., all patients will be seen in the emergency department, where emergency physicians will provide immediate health care and treatment, as well as offer referrals to specialists/departments when necessary.
