2005-2014年产科医院事件统计（HES）数据与出生登记和出生通知数据（以前称为婴儿NHS编号或NN 4 B）相关联，以汇集一些在国家层面上无法获得的关键人口统计和临床数据项。修订了以前用于链接2005-2007年数据的链接算法，以提高链接率并减少重复的HES记录数量。（'ONS出生记录'）如果NHS号码缺失，则使用NHS号码和其他直接标识符进一步与产妇HES分娩和出生记录相关联。在2005-2014年期间，超过94%的出生登记和通知记录与HES分娩记录正确关联。2%的ONS出生记录与HES分娩记录错误关联，5%的ONS出生记录与多个HES分娩记录关联。因此，大量的时间花在质量保证这些files.Conclusion出生登记和通知记录的HES交付记录的链接率稳步提高，从2005年到2014年，由于在两个HES和出生通知数据的患者标识符的质量和完整性的改善。
Introduction Maternity Hospital Episode Statistics (HES) data for 2005-2014 were linked to birth registration and birth notification data (previously known as NHS Numbers for Babies or NN4B) to bring together some key demographic and clinical data items not otherwise available at a national level. The linkage algorithm that was previously used to link 2005-2007 data was revised to improve the linkage rate and reduce the number of duplicate HES records.Methods Birth registration and notification linked records from the Office for National Statistics ('ONS birth records') were further linked to Maternity HES delivery and birth records using the NHS Number and other direct identifiers if the NHS Number was missing.Results For the period 2005-2014, over 94% of birth registration and notification records were correctly linked to HES delivery records. Two per cent of the ONS birth records were incorrectly linked to the HES delivery record and 5% of ONS birth records were linked to more than one HES delivery record. Therefore, a considerable amount of time was spent in quality assuring these files.Conclusion The linkage rate for birth registration and notification records to HES delivery records steadily improved from 2005 to 2014 due to improvement in the quality and completeness of patient identifiers in both HES and birth notification data.
