To establish if there is a learning curve for coblation tonsillectomy.
Regression analysis of data obtained from surgeons identified from the Australian Tonsillectomy Survey.
Thirty otolaryngologists were invited to contribute audit data. Data were stratified into groups of 10 procedures and analysed with regression analysis.
Nineteen (70%) surgeons responded. Complete data were obtained for 1700 cases and return to theatre data on 2062 cases. There was a significant learning curve with respect to both primary (P = 0.050) and secondary (P = 0.028) hemorrhage rates. Mean rates were 0.3% (95% CI 0.1% to 0.7%) and 2.1% (95% CI 1.5% to 2.9%) for primary and secondary bleeds, respectively, with return to theatre in 0.2% (95% CI 0.1% to 0.5%) and 1.3% (95% CI 0.9% to 1.9%), respectively.
The introduction of coblation tonsillectomy into Australia was associated with a statistically significant learning curve with respect to both primary and secondary hemorrhage rates.
确定低温等离子体扁桃体切除术是否存在学习曲线。
对从澳大利亚扁桃体切除术调查中识别出的外科医生所获得的数据进行回归分析。
邀请30位耳鼻喉科医生提供审计数据。数据被分层为每组10例手术，并进行回归分析。
19位（70%）外科医生做出回应。获得了1700例病例的完整数据以及2062例病例的重返手术室数据。在原发性（P = 0.050）和继发性（P = 0.028）出血率方面均存在显著的学习曲线。原发性和继发性出血的平均发生率分别为0.3%（95%可信区间0.1%至0.7%）和2.1%（95%可信区间1.5%至2.9%），重返手术室的比例分别为0.2%（95%可信区间0.1%至0.5%）和1.3%（95%可信区间0.9%至1.9%）。
低温等离子体扁桃体切除术在澳大利亚的引入，在原发性和继发性出血率方面均与具有统计学意义的学习曲线相关。
