The relationship between the level of illumination and the prescription-dispensing error rate in a high-volume Army outpatient pharmacy was investigated. The prescription error rate was determined by direct, undisguised observation and retrospective prescription review under three levels of illumination (45, 102, and 146 foot-candles) during 21 consecutive weekdays. Illumination was controlled in the prescription-checking area of the pharmacy by using additional fluorescent lamps and filters. The three levels of illumination were randomly assigned to the 21 days to provide a total of 7 days of observations per level. The final sample consisted of 10,888 prescriptions dispensed by five pharmacists. The overall prescription error rate (including both content and labeling errors) was 3.39% (369 prescriptions). An illumination level of 146 foot-candles was associated with a significantly lower error rate (2.6%) than the baseline level of 45 foot-candles (3.8%). There was a linear relationship between each pharmacist's error rate and that pharmacist's corresponding daily prescription workload for all three illumination levels. The effect of the observer was minimal. The rate of prescription-dispensing errors was associated with the level of illumination. Ergonomics can affect the performance of professional tasks.
研究了大容量军队门诊药房的光照水平与处方调配错误率之间的关系。在连续21个工作日内，通过在三种光照水平（45、102和146英尺烛光）下进行直接、无掩饰观察和回顾性处方审查来确定处方错误率。通过使用额外的荧光灯和滤光器来控制药房处方检查区域的光照。将三种光照水平随机分配到这21天，每种光照水平共观察7天。最终样本包括由五名药剂师调配的10888张处方。总体处方错误率（包括内容和标签错误）为3.39%（369张处方）。146英尺烛光的光照水平与显著低于45英尺烛光基线水平（3.8%）的错误率（2.6%）相关。在所有三种光照水平下，每位药剂师的错误率与该药剂师相应的每日处方工作量之间存在线性关系。观察者的影响最小。处方调配错误率与光照水平相关。人体工程学可影响专业任务的执行。
