Centrally recorded OPCS codes are based upon district returns. The aim of this study is to determine the accuracy of this system with regard to vascular surgery.
Prospectively recorded audit data for vascular and endovascular procedures were compared with those obtained from the Department of Health and Welsh Office. Five U.K. hospitals were involved in the study. Data were obtained for the twelve months, 1 April 1994-30 March 1995 (these being the most up to date figures available).
The total number of arterial reconstructions based on audit data was 1082. Those recorded by the OPCS codes were 743. This represents a discrepancy of -31.3% (range for the five hospitals: -13.1% to -63.8%). When examining specific codes similar discrepancies were seen. For example, in one hospital 38 AAA repairs were carried out but only two were centrally recorded. However, examination of ICD9 codes (relating to hospital admissions) for that hospital showed that 38 patients with AAA were admitted. A similar wide variation was seen when examining iliac and superficial femoral artery endovascular procedures. Despite the discrepancies of audit and OPCS data, the codes for reconstructions did reflect relative workload of the different hospitals.
This study shows that there is a marked underestimate of vascular workload when comparing central recorded data with that obtained from local audit. Marked variation is seen in the accuracy of data submitted from different hospitals.
集中记录的OPCS编码基于地区回报数据。本研究的目的是确定该系统在血管外科方面的准确性。
将前瞻性记录的血管和血管内手术的审计数据与从卫生部和威尔士办公室获得的数据进行比较。五家英国医院参与了该研究。获取了1994年4月1日至1995年3月31日这十二个月的数据（这些是可获得的最新数据）。
基于审计数据的动脉重建总数为1082例。OPCS编码记录的为743例。这代表差异为-31.3%（五家医院的范围：-13.1%至-63.8%）。在检查特定编码时也发现了类似的差异。例如，在一家医院进行了38例腹主动脉瘤修复手术，但中央记录的只有两例。然而，检查该医院的ICD9编码（与医院入院相关）显示有38例腹主动脉瘤患者入院。在检查髂动脉和股浅动脉血管内手术时也出现了类似的广泛差异。尽管审计数据和OPCS数据存在差异，但重建手术的编码确实反映了不同医院的相对工作量。
本研究表明，将中央记录的数据与从本地审计获得的数据进行比较时，血管工作量被显著低估。不同医院提交的数据准确性存在显著差异。
