Therapeutic Error: Types and Prevention Strategies and Focus about "Look Alike/Sound Alike" and "High Risk" Drugs

Abstract

Introduction: Therapeutic errors are among the main causes of drug-related problems, in terms of enhanced toxicological or reduced therapeutic effect, and concern all stages of the drug chain, from manufacturing to prescription, dispensing and administration. Everyone, pharmacists and doctors in all settings, should be aware of how to prevent and manage them and which drugs are at greatest risk. In this article we will focus on LASA (look alike/sound alike), on FAR (high-risk drugs) and on the guidelines especially for prevention. Methods: The article is a minireview that was written by research in paper and online on PubMed and Embase. We performed a search of any publications available in these databases between the years 1990 and 2022, using the key words: therapeutic errors, misuse / diversion of drugs, drug poisoning. After a review of the titles and abstracts, the articles chosen were considered relevant in providing evidence of the problem. We also added personal knowledge about the topic of the article and used some paper documents. Discussion and Conclusions: Most of the errors in therapy occur during administration, due to errors in doses, posology or interactions or incorrect manipulations of pharmaceutical forms, and in dispensing, due to incorrect interpretation of the prescription or confusion on the packaging in the case of LASAs. Pharmacists and doctors but also patients themselves should pay attention to the time of prescription and doctors to the drug history not only for interactions but also to avoid making mistakes in patients who take drugs with names or packages similar to the one described above. Moreover, attention must be paid in writing the prescription, in dosage, and pharmaceutical forms. Particular attention should be paid to handling by children and to avoiding any misuse of the medicines themselves.
