Medication Errors Associated with Look-alike/Sound-alike Drugs: A Brief Review
Journal of Enam Medical College, 2015
The existence of confusing drug names is one of the most common causes of medication errors. There are many types of medication errors: wrong drug, wrong dose, wrong route of administration, wrong patient etc. Misreading medication names that look similar is a common mistake. These look-alike medication names may also sound alike and can lead to errors associated with verbal prescriptions. Similar sounding drugs may produce confusion and may lead to unintended interchange of drugs causing harm to patients or even patient death. The main aim of the study was to evaluate medication errors related to look alikesound alike drug names and to find out the strategies to prevent these medication errors.

Background: With thousands of drugs currently in the market, the potential for medication errors due to confusing drug names amongst practising physicians, pharmacists and patients is significant. The existence of confusing drug names is one of the most common causes of medication error. There are many look-alikes, sound-alike (LASA) combinations that could potentially result in medication errors. There is insufficient data about medication errors due to LASA. Hence, we conducted the present study to determine the degree of awareness regarding LASA drugs among post graduate medical physicians and Pharmacists.Methods: This study was a cross-sectional, questionnaire-based survey, conducted among 137 year post graduate medical residents of a tertiary care teaching hospital and 121 local pharmacists in an urban metropolitan Indian city.Results: There were 34% resident doctors and 17% pharmacists were aware of concept of LASA drugs. Only 46% resident doctors and 22% pharmacists had knowl...
Exploring the potential for using drug indications to prevent look-alike and sound-alike drug errors
Expert Opinion on Drug Safety, 2017
Background. Look-alike, sound-alike (LASA) drug names are a cause of medication errors with resulting patient harm and healthcare costs. This study assessed to which extent the use of the generic drug name, therapeutic class, health problem, and the U.S. Food and Drug Administration (FDA)-approved indications might be used to differentiate LASA drug pairs. Research design and methods. We collected information about LASA drug pairs reported by the FDA to have look-alike sound-alike similarities. To assess potential for differentiating LASA drug pairs, we compared the following drug characteristics: generic name, therapeutic class, health problem, and FDA-approved indication. Results. For the 33 FDA reported LASA drug pairs we identified a total of 432 FDA-approved indications. Using the generic name, therapeutic class, health problem and drug indication we were able to differentiate 8 (24.2%), 24 (72.7%), 25 (75.8%) and 26 (78.8%), respectively of the 33 LASA drug pairs. Using the generic name, therapeutic class, and health problem we were able to distinguish 31 (7.2%), 212 (49.1%), and 269 (62.3%), respectively of the 432 FDA-approved indications for the LASA drug pairs. Conclusions. Including the FDA-approved indication in the drug prescription may be used to differentiate LASA drug pairs and thus, prevent wrong drug medication errors.

In healthcare, drugs related confusions are one of the major contributors to the inappropriate use of drug therapy. Look-alike and sound-alike (LASA) drugs are a category of drugs having a high potential to confuse the healthcare professionals and patients due to their similar resemblance and pronunciation. Due to the confusing nature of LASA drugs, there is always a possibility of medication errors and potential harm to the patient. So, proper management is very essential to prevent the misuse of LASA drugs. Development, implementation and maintenance of medication policy are highly required for the proper management of medications and ensure patient's safety.

Background: There are many reports regarding various medical institutions' attempts at incident prevention, but the relationship between incident types and impact on patients in drug name errors has not been studied. Therefore, we analyzed the relationship between them, while also assessing the relationship between preparation and inspection errors. Furthermore, the present study aimed to clarify the incident types that lead to severe patient damage. Methods: The investigation object in this study was restricted to "drug name errors", preparation and inspection errors in them were classified into three categories (similarity of drug efficacy, similarity of drug name, similarity of drug appearance) or two groups (drug efficacy similarity (+) group, drug efficacy similarity (−) group). Then, the relationship between preparation and inspection errors was investigated in three categories, the relationship between incident types and impact on patients was examined in two groups. Results: The frequency of preparation errors was liable to be caused by the following order: similarity of drug efficacy > similarity of drug name > similarity of drug appearance. In contrast, the rate of inspection errors was liable to be caused by the following order: similarity of drug efficacy < similarity of drug name < similarity of drug appearance. In addition, the number of preparation errors in the drug efficacy similarity (−) group was fewer than that in the drug efficacy similarity (+) group. However, the rate of inspection errors in the drug efficacy similarity (−) group was significantly higher than that in the drug efficacy similarity (+) group. Furthermore, the occupancy rate of preparation errors, incidents more than Level 0, 1, and 2 in the drug efficacy similarity (−) group increased gradually according to the rise of patient damage. Conclusions: Our results suggest that preparation errors caused by the similarity of drug appearance and/or drug name are likely to lead to the incidents (inspection errors), and these incidents are likely to cause severe damage to patients subsequently.
Medical errors related to look-alike and sound-alike drugs
Anaesth Pain Intensive Care, 2013
Despite recent developments in the inventory management, introduction of electronic drug trolleys and cabinets, color coding of the filled syringes and many more interventions, medication errors could not be eliminated. The most common of these are syringe swap and human errors regarding wrong drug administration due to look-alike drug containers or sound-alike names of the drugs belonging to diverse groups. Many of the fatalities, that occur in third world countries due to these causes, go unnoticed and unregistered. This special article complements two special editorials on the same topic by Professor Joseph D. Tobias et al and Professor Robert Stoelting, a case report, a patient's perspective and a 'Cliniquiz' being published in the current issue of the journal. It discusses salient features of this issue as well as preventive measures and recommendations.
Background Confusion between look-alike and sound-alike (LASA) medication names (such as mercaptamine and mercaptopurine) accounts for up to one in four medication errors, threatening patient safety. Error reduction strategies include computerized physician order entry interventions, and 'Tall Man' lettering. The purpose of this study is to explore the medication name designation process, to elucidate properties that may prime the risk of confusion. Methods and Findings We analysed the formal and semantic properties of 7,987 International Non-proprietary Names (INNs), in relation to naming guidelines of the World Health Organization (WHO) INN programme, and have identified potential for errors. We explored: their linguistic properties, the underlying taxonomy of stems to indicate pharmacological interrelationships, and similarities between INNs. We used Microsoft Excel for analysis, including calculation of Levenshtein edit distance (LED). Compliance with WHO naming guidelines was inconsistent. Since the 1970s there has been a trend towards compliance in formal properties, such as word length, but longer names published in the 1950s and 1960s are still in use. The stems used to show pharmacological interrelationships are not spelled consistently and the guidelines do not impose an unequivocal order on them, making the meanings of INNs difficult to understand. Pairs of INNs sharing a stem (appropriately or not) often have high levels of similarity (<5 LED), and thus have greater potential for confusion. Conclusions We have revealed a tension between WHO guidelines stipulating use of stems to denote meaning, and the aim of reducing similarities in nomenclature. To mitigate this tension and reduce the risk of confusion, the stem system should be made clear and well ordered, so as to avoid compounding the risk of confusion at the clinical level.

Background: Differences in error rates between pharmacists and nurses in terms of drug confirmation have not been studied. The purpose of this study was to analyze differences in error rates between pharmacists and nurses from the viewpoint of error categories, and to clarify differences in recognition regarding drug name similarity. Methods: In this study, preparation errors and incidents were classified into three categories (drug strength errors, drug name errors, and drug count errors) to investigate the influence of error categories on pharmacists and nurses. In addition, errors in two categories (drug strength errors and drug name errors) were reclassified into another two error groups, to investigate the influence of drug name similarity on pharmacists and nurses: a "drug name similarity (−) group" and a "drug name similarity (+) group". Then, differences in error rates of pharmacists and those of nurses were analyzed respectively within three categories and two groups. Furthermore, differences in error rates between pharmacists and nurses were analyzed in each of the three categories and two groups. Results: Error rates of pharmacists for both drug strength errors and drug name errors were significantly higher than that for drug count errors, and similar results were obtained for nurses (P < 0.05). However, there were no significant differences in error rates between pharmacists and nurses in each of the three categories. Furthermore, error rate of nurses was significantly higher than that of pharmacists in the drug name similarity (+) group (P < 0.05), while there was no significant difference in error rates between pharmacists and nurses in the drug name similarity (−) group. Conclusions: These results suggest that in contrast to pharmacists, nurses are easily affected by similarities in drug names. Therefore, pharmacists should offer information on medications having plural strengths or similar names to nurses, in order to minimize damage to patients resulting from errors.
THE ROLE OF DRUG NAMES IN DIFFERENTIATING AND SELECTING THE APPROPRIATE MEDICATION
2024
Each drug has its own unique name to distinguish it from other drugs based on its class. This aims to differentiate one drug from another and make it easier for healthcare professionals to find the appropriate medication. The importance of drug classification and proper storage systems (FEFO/FIFO) for safe and effective use cannot be overstated. In pharmaceutical information services, pharmacists must provide accurate and clear information to doctors, pharmacists, nurses, other healthcare professionals, and patients. Due to a lack of knowledge and understanding among the public regarding diseases, drugs, and drug therapy, guidance and understanding are needed so that patient adherence to treatment can run smoothly during the healing process. Pharmacists are responsible for providing accurate information to patients, including information on indications, appropriate dosage, how to use, contraindications, side effects, and drug interactions with other drugs or food. Furthermore, drug abuse, particularly narcotics, remains a significant issue and requires continuous education for prevention.
