目的：评价描述性信息的完整性和准确性救护车数据与其他两个次要数据来源，即法医报告和医疗记录，在卡拉奇市，巴基斯坦。方法：回顾性分析2003年1月1日至12月31日卡拉奇救护车运送的所有道路交通伤害（RTI）受害者。获得了受害者的姓名、年龄和性别、受伤日期、时间和地点、受伤类型及其结果等信息，然后与法医的数据和住院医疗记录进行了比较。确定了救护车服务数据库中缺失的变量。结果：2003年救护车服务运送了1245名RTI患者，其中81%被送往三家创伤中心之一。20%的人在到达医院之前死亡。340例（27%）中存在缺失变量，其中大多数是唯一标识符，如姓名和年龄（67%）。95%或更多的病例报告了其他变量的数据。医疗检查人员的报告或住院医疗记录都没有对受伤事件的描述。三个数据集中可用变量的一致性从61%到100%不等。结论：关于伤害的二手数据，如救护车报告、法医报告和医疗记录，有明显的局限性。在卡拉奇，除了唯一标识符之外，救护车数据提供的信息似乎与医疗检查人员和住院病人的医疗记录一样准确。
OBJECTIVES: To evaluate the completeness of descriptive information and accuracy of ambulance data when compared with two other secondary sources of data, namely, medical examiners' reports and medical records, in the city of Karachi, Pakistan.METHODS: A retrospective chart review was carried out of all road traffic injury (RTI) victims transported by an ambulance service in Karachi from January 1 to December 31, 2003. Information on the name, age, and gender of the victim, date, time, and place of injury, and type of injury and its outcome was obtained, and then compared with medical examiners' data and inpatient medical records. The variables missing in the ambulance service database were identified.RESULTS: The ambulance service transported 1,245 RTI patients during 2003, 81% of whom were taken to one of three trauma centers. Twenty percent died before reaching hospital. There were missing variables in 340 (27%) cases, the majority of which were the unique identifiers such as name and age (67%). Data on other variables were reported in 95% or more cases. None of the medical examiners' reports or inpatient medical records contained a description of event of injury. The agreement rate for the variables available in the three data sets ranged from 61% to 100%.CONCLUSION: Secondary data on injuries, such as ambulance reports, medical examiners' reports, and medical records, have significant limitations. In Karachi, except with regard to unique identifiers, ambulance data seem to provide information just as accurate as that in medical examiners' and inpatient medical records.
