OBJECTIVE
To quantitatively assess a surgical "learning curve" using the cumulative summation (CUSUM) score technique.
STUDY DESIGN
Application of a CUSUM technique to a consecutive series of surgical cases.
ANIMALS
Consecutive primary cemented total hip replacement (THR; n=116) in 106 dogs.
METHODS
Records of all dogs that had primary canine THR were reviewed. Data retrieved included date of surgery, postoperative complications, and duration of follow-up. The 12-week outcome was analyzed graphically and with a CUSUM technique.
RESULTS
One hundred and one (87%) procedures were "successful" and 15 (13%) developed major complications within 12 weeks (failures). The CUSUM chart clearly demonstrated an initial "learning curve" of ∼44 THR.
CONCLUSION
The CUSUM technique can be used to demonstrate the learning curve for canine THR surgery.
目的
使用累积求和（CUSUM）评分技术对手术“学习曲线”进行定量评估。
研究设计
将CUSUM技术应用于一系列连续的手术病例。
动物
106只犬连续进行初次骨水泥型全髋关节置换术（THR；n = 116）。
方法
回顾所有接受初次犬类THR手术的犬只记录。检索的数据包括手术日期、术后并发症和随访时间。采用图形分析和CUSUM技术对12周的结果进行分析。
结果
101例（87%）手术“成功”，15例（13%）在12周内出现严重并发症（失败）。CUSUM图表清楚地显示了约44例THR的初始“学习曲线”。
结论
CUSUM技术可用于展示犬类THR手术的学习曲线。
