A hospital department focusing on the acute care of patients that present without a prior appointment
This department must be prepared to provide initial treatment for a wide array of illnesses and injuries (some of which may be life-threatening and require immediate attention)
Open to the public 24 hours a day (although staff levels usually vary)
The Emergency Room
![Page 4: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/4.jpg)
Usually placed in its own section of the first floor of the hospital, with its own separate dedicated entrance
Prioritization of cases based on clinical need – achieved through the application of triage.
The Emergency Room
![Page 5: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/5.jpg)
First stage the patient encounters Consists of a brief assessment, set of vital
signs, and the assignment of a chief complaint
Usually completed by an emergency nurse After initial assessment, patients can be
passed to another area of the department or hospital,
A patients’ wait time is based on their clinical need.
Triage
![Page 6: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/6.jpg)
Exceptions: minor ailments may be treated at the initial triage stage
Patients with apparently serious/severe conditions can bypass triage and move to a more appropriate department immediately
Triage

This is the area where the most seriously ill or injured patients will be treated
Important to contain the tools, staff and medication necessary for handling immediately life threatening illnesses and injuries
Typical staffing includes at least one physician and one nurse
May also include hospital pharmacists
Resuscitation area
![Page 8: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/8.jpg)
This department is appropriate for patients that are seriously ill, but not in immediate danger
Examples include chest pain, difficulty breathing, abdominal pain and neurological complaints
Advanced diagnostic testing completed here (lab tests, scans, MRI’s etc.)
Appropriate staff necessary
Acute Care
![Page 9: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/9.jpg)
This area is reserved for patients that do not have immediately life threatening conditions
Examples include fractures, dislocations and lacerations requiring suturing
Minors Area

Results from the 2003 Canadian Community Health Survey
1/8 Canadians 15 or older reported that their most recent contact with a health professional occurred in a hospital ER
Rates of ER use highest among teens and young adults In Ontario, administrative records for the year 2000
showed that trauma represented the largest proportion of all ER visits
Men were slightly more likely than women to have used ER services: 14% versus 12%.
ER use is inversely associated with household income.
Emergency Department Use in Canada
![Page 11: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/11.jpg)
ER use was similar in the provinces and territories.(exceptions were higher use in New Brunswick, Nova Scotia and Yukon)
Residents of rural areas were more likely than urban dwellers to have used an ER
People who reported having a "regular doctor" were just as likely to report ER use as those that did not have a "regular" physician.
Those who had consulted a doctor more than five times in the past year were more likely to use an ER than people who went to the doctor less frequently.
Suggests that ER users are heavy users of other medical services, (need for ongoing care related to the health problem or injury?)

Of the 2.4 million people whose most recent hospital visit had been in an ER, 73% reported receiving excellent or good care.
16% felt their care was fair 11%, felt their care was poor Dissatisfaction with service may be related to over-
crowding, waiting times or lack of understanding for the way hospitals prioritize treatment;
Statistically significant lower rates of dissatisfaction were reported by residents of Quebec and Yukon.
In Ontario, 24% of residents reported dissatisfaction with ER services (higher than the national rate!)

Lidocaine Epinephrine Furosemide Diazepam Haloperidol Succinylcholine Atropine Heparin For an exhaustive list, see Feldman 2001
Common Emergency Room Medications
![Page 14: Emergency Department (ER) Overview](https://reader036.fdocuments.in/reader036/viewer/2022062811/568161ca550346895dd1afe3/html5/thumbnails/14.jpg)
Lidocaine: ◦ Can be used as a local anesthetic when injected
subcutaneously (used for a nerve block). ◦ Used as an antidysrhythmic drug when injected IV (used
to treat cardiac dysrhythmias). ◦ Anesthetic preparations come in 2 forms: with and
without epinephrine. Epinephrine
◦ Used in emergencies to stimulate the heart or dilate the bronchial tree.
◦ Use is limited by cardiac side effects. ◦ Can be mixed with lidocaine to prolong lidocaine’s effect
and to control bleeding.

Furosemide ◦ Acts as a diuretic, therefore allowing the patient to
produce a greater volume of urine.◦ Given to reduce the fluid overload in patients with
CHF or hypertension.◦ Can be given IV or PO.
Diazepam ◦ Benzodiazepine used as a powerful sedative and as
an anti- convulsant for patients with seizures. ◦ Can be used for alcohol withdrawal, cocaine toxicity,
and status epilepticus. ◦ Caution: Ability to produce respiratory depression.

Haloperidol (Haldol)◦ Antipsychotic, powerful sedative properties. ◦ Used for patients who are acting in a psychotic manner. ◦ Caution: Do not use to treat alcohol withdrawal or cocaine
toxicity! Watch dosing, in large quantities can cause patient to become unconscious.
Succinylcholine◦ Paralytic, leads to total muscular paralysis. ◦ Most often used for “rapid-sequence-intubation” to make
tracheal intubation easier and to allow the patient to be mechanically ventilated.
◦ No analgesic properties, paralyzed patients still have the ability to see, hear and feel everything – therfore it is never used without sedation!

Atropine◦ Used to induce the heart to beat faster (i.e.
chronotropy), as an antidote for certain organophosphate poisonings, or sometimes used as a drug for severe asthma.
Heparin◦ Anticoagulant used to prevent blood from clotting. ◦ Used in patients suspected of having a myocardial
infarction

A 53 old male arrives to the arrives to the emergency department (ER) with a myocardial infarction (heart attack). The following steps to treat this patient are taken:1. Triaged to the resuscitation area 2. There he seen by an ER physician and receive oxygen and monitored and
have an early ECG3. Nurse will provide him with Aspirin (if not contraindicated or not already
administered by the ambulance team); morphine or diamorphine will be given for pain; sublingual (under the tongue) or buccal (between cheek and upper gum) nitroglycerin (unless contraindicated by the presence of other drugs)
4. Following the ECG which reveals an ST segment elevation or new left bundle branch block suggests complete blockage of one of the main coronary arteries
5. Patients require immediate reperfusion (re-opening) of the occluded vessel 6. Two ways to accomplish this: thrombolysis (clot-busting medication) or
percutaneous transluminal coronary angioplasty (PTCA). Both of these are effective in reducing significantly the mortality of myocardial infarction
PTCA as it is somewhat more effective than thrombolysis if it can be administered early and being more accepted by most hospitals. Patient may need to be transferred to a nearby facility with facilities for angioplasty

A 25 year old female comes into the ER department with acute exacerbations asthma. The following steps to treat this patient are taken:
1. She is assessed by triage nurse and treated with oxygen therapy, bronchodilators, steroids or theophylline
2. An urgent chest X-ray and arterial blood gases are ordered
3. ER Physician performs an overall assessment of patient from this information and makes a referral home or to the intensive care unit (ICU) if necessary

As part of the interdisciplinary ED care team, pharmacists can provide care to critically ill patients by:
◦ gathering or reviewing medication histories and reconciling patients’ medications
◦ continuously assessing for and managing adverse drug reactions ◦ monitoring patient therapeutic responses (including laboratory
values) ◦ monitoring for patient allergies and drug interactions ◦ providing drug information consultation to emergency
physicians, emergency nurses, and other clinicians ◦ providing consultation on patient-specific medication dosage
and dosage adjustments
