研究了药房环境声音与药剂师配药准确性之间的关系。药剂师在连续23天的每个工作日配药时都被录了下来。研究者检查了每份配药的处方。偏离医生的书面命令被认为是错误。录像带分析用于检测不可预测的、可预测的、不可控制的和可控的声音。采用了受试者内部病例对照研究设计，以确定在填充有错误的处方与没有错误的处方时，环境声音的频率是否显着不同。以每半小时的等效声级（L(eq)）表示的响度与点药错误率的关系进行了分析。平均调剂错误率为3.23%。不可预测的声音、可控的声音和噪音对药剂师的影响显著，导致调剂错误率下降。这些结果表明药师的工作质量不受环境声的不利影响。随着等效声级的增加，错误率增加到一定程度，然后下降。
Associations between ambient sounds and accuracy of pharmacists' prescription-filling performance in a pharmacy was studied. Pharmacists were videotaped as they filled prescriptions each workday for 23 days. Each filled prescription was inspected by the investigator. Deviations from the physician's written order were considered errors. Videotape analysis was used to detect unpredictable, predictable, uncontrollable, and controllable sounds. A within-subjects case control study design was employed to determine whether the frequency of ambient sounds was significantly different when prescriptions with errors, compared with those without errors, were filled. Loudness, in terms of equivalent sound levels (L(eq)) for each half hour, was analyzed for a relationship to dispensing error rate. A mean dispensing error rate of 3.23% was found. Unpredictable sounds, controllable sounds, and noise had a significant effect on pharmacists which resulted in a decreased dispensing error rate. These results suggest that the quality of pharmacists' performance is not adversely affected by ambient sound. As equivalent sound levels increased, the error rate increased to a point, then decreased.
