Among medication errors, confusions between drug names that look and sound alike continues to be a source of concern. One factor that might make errors more likely is when prescribing is done via spoken communication in a noisy environment. Using the neighborhood activation model of word perception as a theoretical framework, I will discuss the results of a study investigating the effect of noise, familiarity, prescribing frequency, frequency-weighted neighborhood probability (FWNP), and phonotactic features on auditory perception of drug names when physicians, pharmacists, nurses, and lay people are asked to recognize drug names. In particular, this study examined whether noise would reduce accuracy, while familiarity, prescribing frequency, FWNP, and sublexical frequency would enhance recognizing drug names. We found that accuracy was influenced by the similarity neighborhood of each drug name and, importantly, that it decreased as noise increased, and that familiar drug names were perceived more accurately than less familiar drug names, although there were some differences across participant groups. Recommendations for reducing errors will be discussed. ------------------------------------------------------------------------ Background readings: "Recent Developments in the Prevention and Detection of Name Confusion Errors" "Designing Safe Drug Names" https://ublearns.buffalo.edu/webapps/blackboard/content/listContent.jsp?course_id=_60597_1&content_id=_1010435_1 ------------------------------------------------------------------------ Complete Fall schedule @ www.cogsci.buffalo.edu/Activities/Colloquium/CLLQf08/2008fall.html Background readings for each lecture are available to UB faculty and students on UB Learns.
