To determine resident physician operative times surrounding their 45th, 86th, and 121st cataract surgery.
Retrospective chart review of 375 surgical records of 25 ophthalmology residents. Groups were compared with each other and to a published surgeon.
The mean operative times of surgeries 43 to 47, 84 to 88, and 119 to 123 were 39.9, 30.0, and 27.2 minutes, respectively. Surgical time decreased 25% from the 45th to the 86th case (P = .0002) and 9% from the 86th to the 121st case (P = .2049). Compared with a published surgeon's time of 26.8 minutes, residents' times were significantly longer around their 45th (P = .0001) and 86th surgery (P = .0012), but nearly identical around the 121st surgery (P = .7022).
Significant decreases in operative time occurred between the 45th and 86th case. Smaller decreases occurred after the 86th case. Residents' operative times approach that of a published ophthalmologist around the 121st case.
确定住院医师在其第45、86和121例白内障手术时的手术时间。
回顾性查阅25名眼科住院医师的375份手术记录。将各组相互比较，并与一位已发表数据的外科医生进行比较。
第43至47例、第84至88例和第119至123例手术的平均手术时间分别为39.9分钟、30.0分钟和27.2分钟。手术时间从第45例到第86例下降了25%（P = .0002），从第86例到第121例下降了9%（P = .2049）。与已发表的外科医生26.8分钟的手术时间相比，住院医师在其第45例（P = .0001）和第86例手术时（P = .0012）的时间明显更长，但在第121例手术时几乎相同（P = .7022）。
手术时间在第45例和第86例之间显著下降。第86例之后下降幅度较小。住院医师在第121例手术时的手术时间接近已发表的眼科医生的手术时间。
