Alphabetic, phonetic, and combined alphabetic and phonetic methods of retrieving online drug information were compared. Twenty-four volunteers participated in the study representing four user groups: physicians, nurses, pharmacists, and nonhealth-care hospital staff. Each subject performed 150 searches, 50 by each retrieval method. Using the alphabetic method, drug information was retrievable only if the drug name was spelled correctly. Using the phonetic method, searches were conducted based on the phonetic spelling of requests (e.g., "symetadine" for cimetidine). The combined method used a phonetic search only after an initial alphabetic search was unsuccessful. The elapsed time between the first entry and an indication that the information had been found or could not be found was determined, and the number of drug names not found and the number of excess tries were counted. There were no significant differences in elapsed time among the three methods. Pharmacists had the shortest mean elapsed time and physicians the longest. The average number of excess tries using the phonetic system was a third of the number required using the alphabetic method. The number of drugs not found showed only slight differences among the three methods. The subjects found the desired information on the first try 67% of the time with the alphabetic method, 66% with the combined method, and 90% with the phonetic method. The phonetic method had an average of 75 matches versus 20 for the alphabetic and combined methods. These results support use of a combined alphabetic and phonetic system for retrieving drug information.
对检索在线药物信息的字母法、语音法以及字母与语音结合法进行了比较。24名志愿者参与了该研究，他们代表了四个用户群体：医生、护士、药剂师和非医疗保健医院工作人员。每位受试者进行150次搜索，每种检索方法各50次。使用字母法时，只有药物名称拼写正确才能检索到药物信息。使用语音法时，搜索是基于请求的语音拼写进行的（例如，用“symetadine”搜索西咪替丁）。组合法仅在初始字母搜索未成功后才使用语音搜索。确定从首次输入到表明已找到或未找到信息之间的 elapsed 时间，并统计未找到的药物名称数量和多余尝试次数。三种方法在 elapsed 时间上没有显著差异。药剂师的平均 elapsed 时间最短，医生的最长。使用语音系统的平均多余尝试次数是使用字母法所需次数的三分之一。三种方法中未找到的药物数量仅显示出轻微差异。受试者使用字母法时在首次尝试时找到所需信息的概率为67%，使用组合法时为66%，使用语音法时为90%。语音法平均有75次匹配，而字母法和组合法为20次。这些结果支持使用字母与语音结合的系统来检索药物信息。
