背景资料：芬兰定期收集出院数据，这是评估伤害流行病学和治疗的宝贵信息来源。该数据库可用于规划伤害预防和重新定向卫生保健系统的资源。最近，我们的出院登记已被用于评估常见骨折手术治疗的发生率。本研究旨在评估芬兰国家医院出院登记册（NHDR）的覆盖范围和准确性，重点是髋部骨折。换句话说，患者住院的股骨粗隆间髋部骨折的有效性进行了评估的NHDR.Methods：NHDR的有效性进行了评估，通过比较出院登记册中的数据与原始患者的记录和X光片在三个独立的医院，坦佩雷大学医院，Hatanpaa市医院坦佩雷，和坎塔-哈梅中心医院。结果：以X线片为金标准，诊断正确率为96%（95%CI：94 ~ 97%）。手术编码的覆盖率为98%（95% CI：96 - 98%），准确度为88%（95% CI：85 - 90%）。受伤的外部原因的覆盖率被发现是95%（95%CI：94至97%）的准确性为90%（95%CI：87至92%）。结论：我们的研究结果表明，芬兰的NHDR的有效性是优秀的诊断准确性和准确性和程序编码和外部原因受伤的覆盖率。该数据库可用于评估损伤流行病学和手术治疗方案的变化。
Background: Hospital discharge data is routinely collected in Finland and it is an invaluable source of information when assessing injury epidemiology as well as treatment. The database can be used when planning injury prevention and redirecting resources of the health care system. Most recently our hospital discharge register has been used to assess the incidence of surgical treatment of common fractures. This study was aimed to evaluate the coverage and accuracy of the Finnish National Hospital Discharge Register (NHDR) focusing on hip fractures. In other words, patients hospitalized for a pertrochanteric hip fracture were used to assess the validity of the NHDR.Methods: The validity of the NHDR was assessed by comparing the data in hospital discharge register with the original patient records and radiographs in three separate hospitals; Tampere University Hospital, Hatanpaa City Hospital of Tampere, and the Central Hospital of Kanta-Hame. The study analysis included 741 patients hospitalized due to pertrochanteric hip fracture between 1st January 2008 and 31st December 2010.Results: The diagnosis was correctly placed on 96% (95% CI: 94 to 97%) of the 741 patients when radiographs were used as golden standard. The procedural coding had coverage of 98% (95% CI: 96 to 98%) and an accuracy of 88% (95% CI: 85 to 90%). The coverage of the external cause for injury was found to be 95% (95% CI: 94 to 97%) with an accuracy of 90% (95% CI: 87 to 92%).Conclusions: Our results show that the validity of the Finnish NHDR is excellent as determined by accuracy of diagnosis and both accuracy and coverage of procedural coding and external cause for injury. The database can be used to assess injury epidemiology and changes in surgical treatment protocols.
