Introduction to Emergency Nursing

Speaking about the Emergency nursing, we should take into account the role of the emergency nurse in the modern hospital and to take into account the most widespread mistakes, done by the nurses in the emergency department. Also, to analyze the causes of these mistakes.

To begin with, emergency nurse is usually the first person, meeting the patient in the hospital. Due to the triage system it is the nurse, who decide, according to the type of the injury, to what kind of doctor the patient should be sent. Sometimes nurses in the emergency department do play a role of the doctor as well –they can prescribe some kind of medicines and to give them to the patient. The kind of mistake in this case can be like this:

•  Wrong diagnose.
• Non –well-organized work of the staff. As to the second one, here can be shown the episode from one of the hospitals, where the mistake was done according to the miscommunication of two nurses.

A 50-year-old man with new atrial fibrillation was placed on a diltiazem drip in the emergency department for rate control. After arriving at the cardiac care unit (CCU), he was noted to be hypotensive and a saline bolus was ordered. The nurse asked a coworker to get her a bag of saline and went to check on another patient. When she returned to the first patient’s bedside, she noticed that an intravenous (IV) bag was already hanging from the IV pole, and thought that her coworker must have placed the saline bag there.

Believing the patient required a rapid saline infusion, she opened the IV up, and the solution infused in rapidly. At that moment, her coworker arrived with the 500 cc saline bag, which caused the patient’s nurse to realize, in horror, that she had given the patient an IV bolus of more than 300 mg of diltiazem. The patient suffered severe bradycardia, which required temporary transvenous pacemaker placement and calcium infusion. Luckily, there was no permanent harm.

The commentary to this case was given by Mary Caldwell, RN, PhD, MBA, and Kathleen A. Dracup, RN, DNSc.

This case study raises several troubling issues. A patient was given an inadvertent overdose of diltiazem during a hypotensive episode due to a miscommunication involving two nurses. Intravenous diltiazem can cause bradycardia, hypotension, and reduced myocardial oxygen consumption, all serious side effects in an already unstable patient.Reported error rates for the administration phase of medication procedures are significant, ranging from 26% to 36%.

With respect to intravenous medication preparation and administration, the possibilities for error are magnified compared with oral agents. In one large study, the investigators reported an overall error rate of 49% for intravenous medications, with 73% of those errors involving bolus injections. Providers are likely to encounter at least four complications specific to intravenous drug administration.

• First, the drug can be infused too quickly or too slowly, unlike oral agents, which have only one rate of administration.
• Second, IV pumps used to control the rate of administration can fail to operate properly or can be set up incorrectly by a nurse.
• Third, preparation of the drug can lead to error, as when the drug is added to an incompatible solution or mixed using the wrong ratio of drug-to-IV solution.
• And finally, the medication can be given through the wrong port, such as into the right atrium rather than into a peripheral vein.

Intuitively, one might guess that the critical care environment would be the site of more medication-related errors than less acute units. In one study that compared intensive care unit (ICU) with non-ICU medication-related errors, preventable adverse drug events were twice as common in ICUs as in non-ICUs. However, when these data were adjusted for the number of drugs used or ordered , there were no differences between the settings. The fact that the patient-to-nurse ratio in the ICU is usually less than or equal to 2:1, while a single nurse on a medical-surgical unit may be responsible for 5 to 10 patients, may mitigate the risk of drug errors in the critical care setting.

The Institute for Safe Medication Practices cites the "five rights" of medication use (right patient, drug, time, dose, and route) as touchstones to aid in the prevention of errors. In this case, following the five rights may have prevented the overdose. However, one must also recognize that many processes used to prevent errors are more difficult to design and implement in critical care units because of the rapidity with which nurses and physicians must act.

Therefore, the basics of safe drug administration practice take on even greater importance. Building in manual redundancies (such as verbal read-backs, similar to those used when administering blood transfusions) may help when there are variances to standard protocol, such as an IV bolus. The high error level documented in IV bolus infusions provides important support for reviewing hospital policies related to their administration. System failures also contributed to the error in this case.

If the patient was unstable enough to require a 500 cc bolus of saline, why did the nurse leave the room to check on another patient? Was the staffing inadequate? Workforce issues have been an enormous concern in recent years as nursing shortages reach crisis proportions. Nurses are stretched thin, and the shortage is felt most acutely among specialty nurses. The clinical impact of staffing shortages on increased mortality and ‘failure-to-rescue’ have been noted.

A survey conducted by NurseWeek/A-ONE found that 65% of RNs felt the shortage impeded their ability to maintain patient safety. Although specific figures regarding the extent of shortages in critical care are not available, the American Association of Critical Care Nurses states that requests for registry and traveling nurses have increased substantially across the country, with a 45% increase for adult critical care, 50% for Pediatric/Neonatal ICUs, and 140% for Emergency Departments.

In the past, most ICUs accepted only experienced nurses (with more than 2 years clinical post-graduate experience) as staff. However, this requirement of previous experience is often waived in times of staff shortages. Although new graduates usually participate in hospital ICU training programs, the learning curves are steep and new nurses may become overwhelmed, leading to errors in communication and execution. A recent Food and Drug Administration (FDA) report listed a number of human factors associated with medication errors.

Performance deficit (as opposed to knowledge deficit), such as seen in this case, was the human factor listed most commonly (30%). Poor communications contributed another 16% to total errors. Thus, this case illustrates a common source of error—a problem of performance related to poor communication. This case study also provides an opportunity to evaluate mistakes on the personal level. A serious, commonly identified shortcoming of the current medical system is the fear of disclosing errors.

When errors occur, the responsible staff member should be an active participant in an evaluative process aimed at preventing similar errors from reoccurring. Results of the evaluation on an individual, unit, and hospital level should be shared with the entire hospital so that similar errors might be prevented in the future.

The tradition of morbidity and mortality conferences, used commonly by physicians, has not been adopted by nursing staff and might be an appropriate strategy if it provided a blame-free environment in which mistakes and system level issues could be discussed openly. Specific measures to prevent errors in situations similar to this case might include:

Standard policy typically dictates the use of IV pumps on all vasoactive drips. (Because it was not specifically noted in this case study, we are compelled to state the obvious.)

Standard policy usually dictates that vasoactive drugs be infused through a site dedicated to only that drug. Therefore, at least one other separate IV site should be used for other fluids and medications. This practice eliminates the need to use the high risk IV and the potential for an inadvertent overdose.

More obvious labeling of ‘high risk’ IV drips (eg, bigger, brighter labels; duplicate labeling on IV   bag, pump, monitor).

Independent double-checks of bolus fluids by nurses prior to administration. Reevaluation of staffing requirements if a patient becomes unstable so that the patient–nurse ratio can be appropriately adjusted. Participation of nurses as well as physicians in morbidity and mortality conferences.

Sometimes the mistakes occur because of inattentiveness of the nurse. By the way, the documents, fulfilled by the nurse, have to be readable and clear not only for the nurse herself, but for the other well-educated staff as well (I mean, the doctors, etc. ). The data’s have to be collected precisely and correctly. But let’s have a look at one of the patients cards, taken from the Hospital. (Pict.1)

The information is just not readable, and it is rather difficult to understand, what were the results. This patient’s card look likes an album of the child, but not as a professionally made card of the well-qualified staff.  Speaking about this case of the 72 years old woman, it is possible to suggest, that the wrong diagnoses have been done, what approximately lead to the death of the patient.

As to the medicines given, it is seen, that not all the medicines needed were given to the patient (at the age of 70 there have to be given some medicines for blood –Heparin and as well some medicines for keeping the heart activity. In this case it looks like that on the base of the cough (probably pneumonia) there was a kind of heart attack (probably cardiac infarction) with the complications as pulmonary edema(or edema of lungs).
