Comparisons of the same patient data in 2004 and 2006 downloads of the DIN-LINK UK primary care database demonstrated unexpected differences in the rates of coronary heart disease between the datasets. Incidence rates were lower between 1996-2003 in the new (2006) download. Patient record checks demonstrated that coronary heart disease codes had been removed in the new download during the run-up to the new contract. Planners need to be aware of such issues when evaluating trends in CHD or other similar conditions.
对DIN-LINK英国初级保健数据库2004年和2006年下载的同一患者数据进行比较后发现,两个数据集之间冠心病发病率存在意外差异。在新的(2006年)下载数据中,1996 - 2003年期间的发病率较低。患者记录检查表明,在新合同签订前的准备阶段,新下载数据中冠心病编码已被删除。规划者在评估冠心病或其他类似疾病的趋势时需要意识到此类问题。
