Periacetabular osteotomy (PAO) is the preferred surgical treatment for hip dysplasia. In Denmark, patients undergoing PAO at two orthopaedic departments are registered in a disease registry, the Aarhus PAO-database. This study aimed to validate the Aarhus PAO-database by assessing the registration completeness compared to the Danish National Patient Registry (DNPR).
Patients registered in the Aarhus PAO-database were compared to patients identified in DNPR as having undergone PAO for hip dysplasia. Further, a random selection of 20 PAO procedures from each registry per year (2014-2021) was validated by comparing the information from the registries to the hospital's electronic medical records.
Between 2014 and 2021, 1144 PAO procedures were registered in the Aarhus PAO-database and 1150 in DNPR. The overall registration completeness was 94.7% (95% CI: 93.3;95.9) with 1116 PAO proceduresincluded in both datasets. The diagnosis and surgery procedure were verified as hip dysplasia and PAO for all randomly selected patients, and almost all discrepancies were resolved (> 95%), using the medical records.
The Aarhus PAO-database has effectively captured all patients who underwent PAO for hip dysplasia from 2014 to 2021. It appears to be a valid resource for future research as well as for ensuring and improving the quality of hip dysplasia treatment.
髋臼周围截骨术（PAO）是治疗髋关节发育不良的首选手术方法。在丹麦，两个骨科部门接受PAO手术的患者被登记在一个疾病登记处，即奥胡斯PAO数据库。本研究旨在通过与丹麦国家患者登记处（DNPR）比较评估登记完整性，从而验证奥胡斯PAO数据库。
将奥胡斯PAO数据库中登记的患者与DNPR中确定为因髋关节发育不良接受PAO手术的患者进行比较。此外，通过将登记处的信息与医院的电子病历进行比较，对每年（2014 - 2021年）从每个登记处随机选取的20例PAO手术进行验证。
2014年至2021年期间，奥胡斯PAO数据库登记了1144例PAO手术，DNPR登记了1150例。总体登记完整性为94.7%（95%CI：93.3；95.9），两个数据集共纳入1116例PAO手术。对于所有随机选取的患者，诊断和手术过程经核实为髋关节发育不良和PAO，并且几乎所有差异（>95%）都通过病历得到了解决。
奥胡斯PAO数据库有效地记录了2014年至2021年期间所有因髋关节发育不良接受PAO手术的患者。它似乎是未来研究以及确保和提高髋关节发育不良治疗质量的有效资源。
