The quality and comprehensiveness of the FDA's National Drug Code Directory (NDCD) in magnetic tape form was evaluated. The internal quality of the tape was measured by performing cross-checks of the four record types found on the tape and by checking for the presence of "illegal" characters. The comprehensiveness of the tape was evaluated by determining the extent to which a sample of items from nine community and hospital pharmacies could be matched with code numbers on the NDCD tape. A second test of comprehensiveness measured the match rate between the shelf stock sample and National Drug Code (NDC) numbers in a magnetic tape supplied by a regional wholesaler. External quality was measured by comparing the NDC numbers on the containers of items from the shelf sample with the corresponding information in the NDCD tape. More than 300 discrepancies among the four types of records were discovered, and more than 100 "illegal" characters were present in each of the four record types. Matches on the NDCD tape could be found for 80% of the items in the shelf stock sample and 69.5% of the items in the tape supplied by the wholesaler. A total of 156 errors were discovered when the codes on containers in the shelf sample were matched with the NDCD tape information, yielding an error rate of 6.5%. Because of the 6.5% error rate, the usefulness of the NDCD tape is questionable. Since only 80% of an off-the-shelf sample of drugs had matches on the NDCD tape, about 20% of drug products would have to be matched with some other information source. How these figures for the NDCD tape compare with figures for proprietary tapes is not known.
对美国食品药品监督管理局（FDA）磁带形式的国家药品代码目录（NDCD）的质量和全面性进行了评估。通过对磁带上发现的四种记录类型进行交叉核对以及检查“非法”字符的存在来衡量磁带的内部质量。通过确定来自九家社区和医院药房的一组样本项目与NDCD磁带上的代码编号的匹配程度来评估磁带的全面性。全面性的第二项测试测量了货架库存样本与区域批发商提供的磁带上的国家药品代码（NDC）编号之间的匹配率。通过将货架样本中项目容器上的NDC编号与NDCD磁带中的相应信息进行比较来衡量外部质量。在四种记录类型中发现了300多个差异，并且在每种记录类型中都存在100多个“非法”字符。在NDCD磁带上可以找到货架库存样本中80%的项目以及批发商提供的磁带中69.5%的项目的匹配项。当货架样本中容器上的代码与NDCD磁带信息进行匹配时，总共发现了156个错误，错误率为6.5%。由于错误率为6.5%，NDCD磁带的实用性值得怀疑。由于货架上的药品样本中只有80%在NDCD磁带上有匹配项，大约20%的药品产品将不得不与其他信息源进行匹配。尚不清楚NDCD磁带的这些数据与专有磁带的数据相比如何。
