To evaluate the accuracy of immunization records transcribed into a computer-based immunization tracking system and to assess factors that contribute to inaccurate or incomplete immunization record keeping.
Computer-stored immunization records were analyzed for 2098 children up to 2 years of age at the time of their most recent well-child visit to the UCLA Children's Health Center over a 12-month period. For children whose immunizations were not up to date, the computer-stored records were analyzed for sources of inaccuracy by comparison with the handwritten records from which the computer-stored data were transcribed.
An underimmunization rate of 22.5% (472 of 2098) was observed based on analysis of the computer-stored records. Comparison of the computer-stored and handwritten records revealed an overall transcription error rate of at least 10.2%. In addition, 38.4% of these apparently underimmunized children had received unrecorded immunizations from providers outside UCLA. When transcription errors were corrected and other available sources of immunization data were taken into account, the estimated rate of underimmunization decreased from 22.5% to 10.9%.
Unavoidable inaccuracies can diminish the utility of the data recorded in an immunization tracking system. Some inaccuracies are related to the process of transcription, but failures to record and communicate immunization data consistently also contribute to the inaccuracy of computer-stored immunization records.
评估转录到基于计算机的免疫接种追踪系统中的免疫接种记录的准确性，并评估导致免疫接种记录不准确或不完整的因素。
在12个月的时间里，对2098名年龄在2岁及以下、最近一次到加州大学洛杉矶分校儿童健康中心进行健康检查的儿童的计算机存储免疫接种记录进行了分析。对于免疫接种未达标的儿童，通过将计算机存储记录与转录这些数据的手写记录进行比较，分析计算机存储记录中的不准确来源。
根据对计算机存储记录的分析，观察到免疫接种不足率为22.5%（2098名儿童中有472名）。计算机存储记录与手写记录的比较显示，总体转录错误率至少为10.2%。此外，这些明显免疫接种不足的儿童中有38.4%接受了加州大学洛杉矶分校以外的医疗机构未记录的免疫接种。当纠正转录错误并考虑其他可用的免疫接种数据来源时，估计的免疫接种不足率从22.5%降至10.9%。
不可避免的不准确之处会降低免疫接种追踪系统中记录的数据的效用。一些不准确与转录过程有关，但免疫接种数据记录和传达的不一致也导致了计算机存储的免疫接种记录的不准确。
