The emergency department in a hospital is always at a high stake position and has a fast paced environment that is designed to save lives and stabilize high risk individuals and patients in crisis. Cases that appear in the ER can require urgent medical attention or may even be true. medical emergency. The difference and necessity in between them can be blurry. The ER is often crowded with patients who require urgent medical surveillance more often than not and this can delay care for true medical emergencies at times. However, protocols are in place- triage systems are designed specifically for this purpose. Doctors must educate patients about their condition and explain clearly if it is a medical emergency or not. Healthcare faculties must provide information about any red flags associated with their condition; this can help in crowd management, equal treatment availability and less chaos.

Hospital Emergency Services

Hospital emergency services or commonly called as the casualty wing or department is the primary gateway for life threatening conditions. This department operates 24/7 and prioritizes patients based on severity of the condition.

ER vs OPD

The patient and their bystanders must understand the difference between emergency care and urgent care. Knowing this difference can save the life and wallet of the patient.

Conditions that require emergency room:

If there is difficult breathing, crushing sensation in the chest – may be a heart attack
If there is sudden weakness, slurred speech, drooping – may be a stroke
Uncontrolled condition of bleeding or compound fracture
A high fever that won’t break and brings on severe confusion.

OPD care is assessed based on the severity of the conditions – like minor sprain, earache, sore throat, shallow cut which needs few stitches, routine vaccination, minor flu symptoms etc. which can be handled by urgent or OPD care.

Triage System In ER

The patient arriving at the emergency room does not wait in line for treatment; instead they go to the triage room, which means ‘to sort’. The severities of symptoms are classified on priority level, after a quick initial assessment of the vitals.

Level 1 priority is given to cases that are characterised under resuscitation which is seen in cardiac arrest, major trauma which has no waiting time and the importance given is immediate.
Level 2 priorities are emergent cases that come with chest pain, stroke symptoms, burns etc. which means there is a wait time of about less than 15 mins.
Level 3 to 5 are characterised under urgent, less urgent and non urgent categories respectively that include abdominal pain, high fever, moderate asthma, minor fractures, simple cuts and sore throat, medication refills. The wait time can vary from 30 mins to 2+ hours depending on urgency and availability of personnel.

Emergency Medical Response

Doctors and nurses that are in the ER treat critical patients with several common life-saving procedures like endo-trachea intubations, procedural sedations and central line placements respectively.

Emergency medical responses are coordinated systems designed to provide immediate care in life threatening situations. Modern emergency response systems function with just a call for help to a unified emergency number that is streamlined to reduce confusion during a crisis. In India, the emergency numbers include 112, 108, 102 etc. which provide emergency ambulance, patient transport and nationwide emergency help.

These numbers help critical patients reach best emergency hospitals located nearest to the patient or even the best multispecialty hospitals in their respective cities, for more advanced care.

Conclusion

Dealing with a medical crisis is as much about preparation, as is getting the right kind of care at the right time. Understanding the triage system and early identification of red flags in the patient’s parameters can help in dropping regular OPD visits and focus on getting true emergency help. This segregation of severity can help in managing resources and saving lives in the most effective manner in a hospital. Medical emergencies are unpredictable, but the response time to these conditions need not be. Using the unified help line number like 112 etc. can help a critical patient to undergo life saving procedures, without wasting precious time. Caregivers should also be aware of where and how to get help and must be able to explain symptoms- as and when they occur, so emergency personnel can deal with the condition in the right manner.
