A Day in the Life in the Emergency Department: What Really Happens on Shift
You step through the double doors of the Emergency and Trauma Department (ETD) at 2:45 PM. The familiar sounds greet you: cardiac monitors beeping, nebulisers running, telephones ringing and staff trying to communicate over the chaos. The department is already busy.
For anyone starting an emergency department posting, whether as a house officer or medical officer, the first few shifts can feel overwhelming. There is a constant stream of patients, competing priorities, and decisions that often need to be made before all the information is available. While our earlier piece on Why I Chose Emergency Medicine: Thriving in the First Minute touches on the adrenaline and career philosophy of resuscitation, this article takes a closer look at the operational reality of an emergency department shift in Malaysia. Understanding the operational anatomy of a daily shift gives you a clearer window into what life in the specialty genuinely looks like.
Hours 00 to 02: Handover, Zoning, and the Boarding Reality
ETDs in Malaysian public hospitals commonly operate through morning (Pagi), evening (Petang), and night (Malam) shifts, although the exact arrangements depend on the hospital and its staffing needs.
Every shift often begins with a handover from the outgoing team. This is more than a routine exchange of patient names, but rather inheriting the unfinished momentum of the day. It is an opportunity to understand the clinical priorities, identify potential risks, and anticipate what may happen over the next few hours. A structured handover, using an approach such as SBAR (Situation, Background, Assessment, Recommendation), helps ensure that important information is not missed.
Understanding the department’s zoning system is equally important. Most Malaysian emergency departments operate using a three-tier triage framework: Red Zone (Zon Merah) for immediate resuscitation, Yellow Zone (Zon Kuning) for semi-critical cases, and Green Zone (Zon Hijau) for ambulatory, non-critical presentations. Each zone has different operational demands, but patient acuity can change at any time. A patient initially assessed as stable may deteriorate, while a patient in the Yellow Zone may require escalation to the Red Zone.
One of the realities that new doctors quickly encounter is patient boarding. This occurs when patients have been assessed and accepted for inpatient admission but remain in the Emergency Department while waiting for an available ward bed.
In busy tertiary hospitals where daily volumes exceed 250 to 350 patients, boarding can significantly affect ETD capacity. Patients may occupy monitored beds for prolonged periods, while new critically ill patients continue to arrive.
This is why an emergency doctor must look beyond the patient immediately in front of them. Knowing who is deteriorating, who needs reassessment and which patients are awaiting admission is part of maintaining situational awareness across the department.
Hours 02 to 05: Navigating Yellow Zone and Managing the Red Zone Crash
By mid-afternoon, the department is usually operating at full pace. This is where emergency medicine becomes an exercise in parallel processing. A house officer may be reviewing patients, obtaining vascular access, taking blood samples, arranging investigations and following up results. It is also an opportunity to develop procedural skills, clinical reasoning and the ability to recognise patients who require escalation.
The medical officer's responsibilities extend beyond completing individual reviews. They must prioritise patients, interpret investigations, initiate treatment, reassess response to therapy and coordinate referrals. This may involve reviewing serial ECGs, managing acute asthma, assessing patients with sepsis or identifying subtle changes in a patient's clinical condition.
At the same time, the Red Zone must remain ready for the next emergency.
When the trauma bell chimes or an alert crackles through the radio. A pre-hospital ambulance retrieval team brings in an unstable poly-trauma victim from a motor vehicle accident. The team immediately pivots:
The Team Leader (Emergency MO or Specialist): Positions themselves at the foot of the bed, orchestrating the primary survey and directing resuscitation while maintaining a clear overview of the patient’s clinical condition and team dynamics.
The House Officer: Establishes wide-bore intravenous access, draws urgent laboratory investigations, and assists with arterial blood gas sampling.
The Penolong Pegawai Perubatan (PPP): Secures the airway equipment, prepares surgical airway sets if required, and connects dynamic continuous monitoring.
The Nursing Staff: Administers emergency medications, tracks fluid balance, and prepares urgent transfusions.
What matters is not simply how quickly the team completes the primary survey. It is whether the team identifies life-threatening problems, initiates appropriate treatment and makes timely decisions.
This ability to move between different levels of acuity is one of the defining features of emergency medicine. Within the same shift, you may move from assessing a patient with a minor injury to coordinating the resuscitation of a critically ill trauma patient.
The challenge is not just knowing what to do. It is knowing what needs to be done first, what can safely wait and when to ask for help.
Hours 05 to 08: Referrals, Patient Flow and Shift Closure
As the evening progresses, managing patient flow becomes increasingly important.
Some patients have completed their ED assessment and require admission under Internal Medicine, Surgery, Orthopaedics or other specialties. Clear, concise referrals supported by relevant clinical findings help facilitate timely decisions and appropriate disposition.
However, inpatient bed availability and ward capacity can delay admissions. When referral or admission issues arise, a structured escalation approach helps prevent unnecessary delays:
Practical steps for referral escalation:
Initial referral: The referring medical officer contacts the receiving team, presenting the clinical findings, working diagnosis, treatment initiated and reason for admission.
Clarify the decision: If the referral is not accepted or delayed, clarify the clinical concerns, admission criteria and any additional information or intervention required.
Medical officer-to-medical officer discussion: Discuss unresolved clinical concerns directly with the respective medical officer to reach a clear management plan.
Escalate to senior clinicians: If the issue remains unresolved, involve the ED specialist and the receiving team's senior clinician for further discussion.
Address bed availability: If the patient is accepted but awaiting a bed, liaise with the Bed Management Unit (BMU) or relevant bed coordinator to clarify bed allocation and anticipated transfer.
Document and reassess: Record referral discussions, decisions, outstanding plans and escalation. Continue appropriate treatment, monitoring and reassessment while the patient remains in ED.
The objective is not to shift responsibility between departments, but to ensure timely decisions, clear accountability and patient safety.
Our responsibility does not end once a referral is made. Patients boarding in the ED still require ongoing assessment, monitoring and treatment while awaiting admission.
Meanwhile, the Green Zone may experience an increase in walk-in patients after working hours. Even among seemingly minor presentations, we must remain alert to patients with potentially serious underlying conditions.
Before the shift ends, the outgoing team must provide a structured handover covering unstable patients, pending investigations, outstanding referrals and ongoing management plans.
A safe handover ensures continuity of care and a smooth transition of responsibility to the incoming team. The shift may end, but our responsibility is to ensure that no patient is left without a clear plan.
What I Have Learned About Working in Emergency Medicine
Emergency medicine is fast-paced, unpredictable and demanding. What makes it challenging is the need to make timely decisions amid uncertainty, recognise clinical deterioration and prioritise competing demands. It requires more than clinical knowledge and procedural skills; it demands sound judgement, adaptability and the ability to maintain situational awareness.
Above all, emergency medicine is a team effort. From resuscitation to routine patient reviews, referrals and handovers, every team member plays an important role in patient care. For junior doctors, the ED offers valuable opportunities to develop clinical confidence and skills under supervision. Ultimately, being a good emergency doctor is not just about how quickly we act or how many procedures we perform, but how well we prioritise, work together and make safe decisions for our patients.
Key Takeaways
Malaysian Emergency & Trauma Departments (ETDs) function on a structured three-tier triage system (Red, Yellow, Green) supported by dedicated procedural areas like asthma bays and observation wards. Learning the zoning system, patient allocation, staffing structure and escalation pathways early in your posting is essential.
Shift work is demanding and physically intense, but offers protected hours and clean handovers compared to 24-hour ward calls.
Working as a team: Inter-professional collaboration between doctors, PPPs, and nurses is important for managing critical resuscitations and boarding bottlenecks.
Recognise your limits: Junior doctors gain rapid hands-on procedural competence and acute diagnostic acumen during their emergency rotation, within an appropriate level of supervision.
Frequently Asked Questions
What is the difference between working an ED shift versus being on-call on the wards?
Emergency doctors work scheduled shift blocks, typically around seven to eight hours per shift, with dedicated clinical handovers. Each shift has a defined handover, allowing clinical responsibility to be transferred to the incoming team.
Ward-based on-call duties may involve a different pattern of work, including ward rounds, urgent reviews, overnight calls and post-call responsibilities. The actual hours and arrangements vary between hospitals and departments.
One of the advantages of shift-based work is having a more defined transition between working periods. However, this does not mean the work is less demanding. ED shifts can be intense, with sustained clinical activity throughout the shift.
Do house officers get to lead resuscitations during an emergency department shift in Malaysia?
House officers are encouraged to take an active, hands-on role during resuscitations, including performing chest compressions, obtaining vascular access, arterial punctures and point-of-care sampling, within a closely supervised learning environment. Through both observing and being observed, they gain opportunities to practise, receive immediate feedback, recognise and learn from mistakes, and improve their clinical skills. Learning is encouraged, but patient safety remains paramount: definitive airway interventions, resuscitation leadership and major triage escalations remain under the direct supervision and clinical responsibility of the Emergency Medical Officer or Emergency Physician, who provides guidance and intervenes when necessary.
How do emergency teams manage disagreements with inpatient teams over ward admissions?
Admission decisions should be based on the patient's clinical condition, diagnostic findings, relevant clinical practice guidelines and the need for inpatient management.
Clear and objective communication is important. When disagreements arise, the medical officers involved should discuss the clinical concerns and clarify the management plan. Unresolved issues or concerns affecting patient safety should be escalated promptly through the respective senior clinicians or specialists.
The objective is not to determine which department is right, but to ensure that the patient receives appropriate and timely care.
What postgraduate pathways exist for emergency medicine in Malaysia?
Doctors can pursue the local 4-year Master of Emergency Medicine (MMed) programme after completing housemanship and at least one post-registration clinical year. Alternatively, doctors can enter the parallel pathway leading to Fellowship of the Royal College of Emergency Medicine (FRCEM UK) after meeting Ministry of Health criteria, including service requirements and qualifying examinations.
Both routes involve structured postgraduate training, clinical experience and assessment. Entry requirements, service requirements and examination arrangements may change, so prospective trainees should refer to the latest Ministry of Health Malaysia and relevant training programme requirements.
Is Emergency Medicine the Right Specialty for You?
Choosing a specialty is a significant career decision. Emergency medicine offers a unique combination of acute clinical care, procedural skills, diagnostic reasoning, teamwork and operational leadership. It also requires adaptability, resilience and the ability to remain focused when the department is under pressure.
The best way to understand the specialty is to speak to doctors who are practising it, observe the department in action and experience the working environment yourself.
