In nursing, we can all agree that ensuring patient safety and accurate medication administration are critical responsibilities. However, the challenge of Look-Alike Sound-Alike (LASA) drugs presents a significant risk in our everyday clinical practice. Look-Alike Sound-Alike (LASA) drugs are medications that have names that either look similar when written or sound similar when spoken, increasing the risk of medication errors.
-
Look-Alike: Medications with similar packaging, labeling, or physical appearance (e.g., size, shape, color).
-
Sound-Alike: Medications with names that sound similar when spoken (e.g., phonetic resemblance).
These errors can occur at various stages of the medication use process, including prescribing, dispensing, and administration. As nurses, we are on the front lines of both dispensing and administering drugs, so we have to be particularly vigilant in recognizing and managing LASA risks to protect our patients. Understanding the implications of LASA drugs and implementing strategies to minimize these risks are critical components of our practice, highlighting the importance of continuous education, meticulous attention to detail, and the utilization of safety protocols.
Despite the risks they pose, LASA drugs are relatively common in the pharmaceutical world. The Institute for Safe Medication Practices (ISMP) has identified hundreds of drug name pairs prone to confusion. Studies indicate that LASA errors constitute a significant portion of medication errors reported in healthcare settings. Some studies estimate that they contribute to up to 25% of all reported medication errors. Even more alarming is that LASA errors have been associated with severe patient harm, including adverse drug reactions, prolonged hospital stays, and even fatalities in extreme cases.
When I was teaching undergraduate nursing students, I was never in favor of scare tactics, but I did relate some real-life instances of LASA errors because they hit home. One example I recall perfectly illustrates this problem:
A nurse got an order to administer medication to a patient with severe hypertension. The drug prescribed was Clonidine, a common antihypertensive. However, due to the similarities in packaging and naming, the nurse inadvertently selected Clonazepam, a medication used to treat anxiety and seizures, from the medication cart. Both drugs were stored in similar-looking vials, and their names were almost identical in appearance, a classic case of look-alike, sound-alike (LASA) drugs.
Despite her usual practice of double-checking medications, the busy ward's pressure and urgency led to the fatal mistake. The Clonazepam was given instead of the Clonidine, and within minutes, the patient began showing signs of severe sedation and respiratory distress. Realizing the error, the nurse immediately alerted the medical team, but despite their rapid response, the patient suffered a cardiac arrest and could not be revived.
Most recently in the news, recall the case of RaDonda Vaught, who accidentally gave a patient vecuronium instead of the ordered Versed when the automated dispensing unit failed, and she overrode the system. The patient went into cardiac arrest and subsequently suffered permanent brain death. While multiple system failures led to this tragedy, a LASA-related error was one. For all registered nurses, I think this case hit especially hard. Despite the failings of the hospital system that contributed to the error, RaDonda herself was criminally charged, stood trial, and was found guilty of criminally negligent homicide and gross neglect of an impaired adult.
This table provides several examples of commonly prescribed drugs that are at high risk for LASA errors.
LASA medication errors can occur at multiple steps in the medication administration process. Here are the key stages where these errors are most likely to happen:
Prescribing
-
Selection error: Due to the similarity in medication names, a prescriber may inadvertently select the wrong medication from a dropdown menu in an electronic health record (EHR) or write an incorrect name on a prescription pad.
-
Miscommunication: Oral communication between healthcare providers or the pharmacy can lead to misinterpretation of similar-sounding medication names.
Transcribing
-
Data entry errors: When prescriptions are transcribed manually into another system, such as from a written prescription to a pharmacy system, errors can occur due to misreading or mistyping the names of similar-sounding or similar-looking drugs.
Dispensing
-
Selection errors: Pharmacists or pharmacy technicians might pick the wrong medication off the shelf due to packaging and labeling that look similar.
-
Labeling errors: Incorrect labels might be applied to medications, especially if multiple medications with similar names are stored near each other.
Administering
-
Medication preparation errors: A nurse might prepare the wrong medication dosage or formulation, confusing it with a similar one.
-
Delivery errors: A nurse might administer the wrong drug at the point of administration, especially in high-stress environments like emergency rooms or intensive care units.
Monitoring
-
Recognition of adverse effects: After administration, failure to recognize adverse drug reactions due to the administration of the wrong medication can further complicate the patient's condition.
Specific safeguards, including barcoding, double-check systems, and electronic verification, can help reduce the risk of LASA errors at each step. These tools, combined with thorough training and awareness education for nurses and nursing students alike, are essential to minimize these potentially dangerous mistakes and promote patient safety.
The simulated medication administration simulator developed by Sim2 Grow offers an innovative approach to training nursing students or newly hired nurses. Here’s how using our system can enhance nursing education and patient safety practices while also reducing the likelihood of look-alike/sound-alike (LASA) medication errors:
Enhanced Familiarity with Medications
Nursing students can interact with virtual representations of various medications using the Sim2Grow simulator, learning to recognize subtle differences in labeling and names that might get confused in real-life scenarios. This repeated exposure helps develop a strong visual memory of specific characteristics that distinguish similar medications.
Practice in a Safe Environment
The Sim2Grow simulator allows nursing students to make mistakes in a controlled, simulated environment where patients cannot be harmed. This opportunity to learn from errors reinforces correct practices and clarifies the consequences of mistakes such as mixing up LASA drugs.
Real-time Feedback and Correction
Students interact with the simulation and receive real-time feedback on their actions. If a LASA error occurs in which the wrong medication is scanned, the Sim2Grow simulator highlights this mistake and returns the student to the dispensing cart to correct the error.
Simulation of Stressful Scenarios
The Sim2Grow simulator can help recreate high-pressure scenarios that are common in clinical settings where LASA errors are more likely to occur. By practicing in these simulated stressful environments, students can develop the calm and focus needed to administer medications carefully, even under pressure.
Repetition and Mastery
Through repeated medication administration practice sessions using the Sim2Grow simulator, students can master the correct procedures for medication administration, including double-checking medication names, dosages, and patient details. This repetition solidifies safe practices and reduces the likelihood of medication errors in actual clinical situations.
By integrating Sim2 Grow’s medication administration simulator into your nursing program, your institutions can significantly enhance the competence and confidence of your nursing students. This technological advancement prepares them better for the complexities of medication administration and is crucial in improving patient safety and quality of care in their future professional practices.
