院外心脏骤停结局（OHCAO）项目旨在了解英国院外心脏骤停（OHCA）的流行病学和结局。这项数据连接研究是民航组织的一个分项目。其目的是确定将OHCAO数据与国民保健服务（NHS）患者人口统计数据和国家统计局（ONS）在NHS个人人口统计服务（PDS）数据库中保存的死亡日期数据联系起来的可行性，以提高OHCAO人口统计数据的质量，并对OHCA的30天生存率进行分析。数据收集时间为2014年1月1日至2014年12月31日，作为由10名英国NHS救护车服务人员参加的OHCA前瞻性观察性研究的一部分。28729例OHCA病例接受了紧急医疗服务的复苏尝试，并被纳入研究。数据连接是利用全国保健数据提供者NHS Digital提供的数据连接服务进行的。为了评估数据关联的可行性，选择了3120例病例的随机样本。将样本安全转移至NHS Digital，使用OHCAO患者人口统计学数据进行匹配，以返回之前缺失的人口统计学数据并提供ONS死亡日期数据。共有2513例（80.5%）OHCAO病例与NHS PDS数据库中的患者匹配。使用链接过程中，缺失的人口统计学数据检索1636（72.7%）的2249 OHCAO案件，以前不完整的人口统计学数据。返回的ONS死亡日期数据允许分析30天生存状态。结果显示，30天存活率为9.3%，未知存活率从46.1%降至8.5%。在该样本中，OHCAO登记处和NHS PDS数据库之间的数据链接被证明是可行的，提高了人口统计学数据质量，并允许分析30天生存状态。
The Out-of-Hospital Cardiac Arrest Outcomes (OHCAO) project aims to understand the epidemiology and outcomes of out-of-hospital cardiac arrest (OHCA) across the UK. This data linkage study is a subproject of OHCAO. The aim was to establish the feasibility of linking OHCAO data to National Health Service (NHS) patient demographic data and Office for National Statistics (ONS) date of death data held on the NHS Personal Demographics Service (PDS) database to improve OHCAO demographic data quality and enable analysis of 30-day survival from OHCA. Data were collected from 1 January 2014 to 31 December 2014 as part of a prospective, observational study of OHCA attended by 10 English NHS Ambulance Services. 28 729 OHCA cases had resuscitation attempted by Emergency Medical Services and were included in the study. Data linkage was carried out using a data linkage service provided by NHS Digital, a national provider of health-related data. To assess data linkage feasibility a random sample of 3120 cases was selected. The sample was securely transferred to NHS Digital to be matched using OHCAO patient demographic data to return previously missing demographic data and provide ONS date of death data. A total of 2513 (80.5%) OHCAO cases were matched to patients in the NHS PDS database. Using the linkage process, missing demographic data were retrieved for 1636 (72.7%) out of 2249 OHCAO cases that had previously incomplete demographic data. Returned ONS date of death data allowed analysis of 30-day survival status. The results showed a 30-day survival rate of 9.3%, reducing unknown survival status from 46.1% to 8.5%. In this sample, data linkage between the OHCAO registry and NHS PDS database was shown to be feasible, improving demographic data quality and allowing analysis of 30-day survival status.
