You book an appointment at a GP clinic and the name on the door belongs to a doctor you have never met. That is often a locum: a fully registered physician covering for the regular general practitioner while they are on leave, training, or unavailable.
Locum, resident, and travelling doctor sound similar but mean different things in Singapore's healthcare system. This guide explains what locum doctors do, how they are credentialed, and what to expect when one sees you.
Locum Doctors Fill Temporary Gaps in Clinic Coverage
Locum comes from the Latin locum tenens, meaning "placeholder."
A locum doctor is a fully certified physician who steps in temporarily when the regular doctor is away for vacation, training, illness, or other reasons.
Same Clinical Duties as the Regular GP
Locum doctors perform the same work as the general practitioners they replace: consulting patients, diagnosing conditions, prescribing treatments, and carrying out procedures.
Many locums have worked across multiple specialties and clinic settings, which gives them a broad clinical range even though they are covering temporarily.
Licensing and Training Requirements in Singapore
Locum doctors must hold a full medical licence. In Singapore that means completing an MBBS programme, finishing residency training, and registering with the Singapore Medical Council.
Additional board certifications may apply depending on their specialty background.
Skills Locums Need That Permanent GPs May Not
Locum work demands a specific skill set:
- Adaptability – moving between clinics and patient populations quickly.
- Communication – explaining care clearly to patients who expected a different doctor.
- Decision-making – diagnosing and treating without the benefit of prior visit history.
Locum vs Resident Doctor: Not the Same Role
Both are qualified doctors, but their positions differ.
Locum doctors are fully licensed physicians who fill temporary vacancies. Many have years of experience across specialties including psychiatry, anaesthesiology, surgery, dermatology, gynaecology, neurology, allergy and immunology, and paediatrics.
Resident doctors are physicians still in training, typically working in hospitals under supervision to specialise in one area of medicine.
Is It Safe to See a Locum Doctor?
Yes. Locum doctors are fully certified and held to the same clinical standards as permanent GPs.
If you prefer continuity of care with one doctor who knows your history, ask whether your regular GP is available or note the locum's name for your records. For non-urgent issues, a locum at your enrolled clinic is appropriate.
For chest pain, severe injury, or stroke symptoms, skip the GP queue and follow GP vs A&E guidance or call 995.
What to do next
Before a weekend or public holiday visit, call the clinic to confirm which doctor is on duty. If you prefer continuity, ask whether your usual GP is available or note the locum's name for follow-up records.
