The perceived difficulty of steps of manual small incision cataract surgery among trainees in rural China was assessed.
Cohort study.
Fifty-two trainees at the end of a manual small incision cataract surgery training programme.
Participants rated the difficulty of 14 surgical steps using a 5-point scale, 1 (very easy) to 5 (very difficult). Demographic and professional information was recorded for trainees.
Mean ratings for surgical steps.
Questionnaires were completed by 49 trainees (94.2%, median age 38 years, 8 [16.3%] women). Twenty six (53.1%) had performed ≤50 independent cataract surgeries prior to training. Trainees rated cortical aspiration (mean score ± standard deviation = 3.10 ± 1.14) the most difficult step, followed by wound construction (2.76 ± 1.08), nuclear prolapse into the anterior chamber (2.74 ± 1.23) and lens delivery (2.51 ± 1.08). Draping the surgical field (1.06 ± 0.242), anaesthetic block administration (1.14 ± 0.354) and thermal coagulation (1.18 ± 0.441) were rated easiest. In regression models, the score for cortical aspiration was significantly inversely associated with performing >50 independent manual small incision cataract surgery surgeries during training (P = 0.01), but not with age, gender, years of experience in an eye department or total number of cataract surgeries performed prior to training.
Cortical aspiration, wound construction and nuclear prolapse pose the greatest challenge for trainees learning manual small incision cataract surgery, and should receive emphasis during training. Number of cases performed is the strongest predictor of perceived difficulty of key steps.
评估了中国农村受训者对手动小切口白内障手术步骤的感知难度。
队列研究。
结束手动小切口白内障手术培训计划的 52 名受训者。
参与者使用 5 分制对 14 个手术步骤的难度进行评分,1 分(非常容易)至 5 分(非常困难)。记录受训者的人口统计学和专业信息。
手术步骤的平均评分。
49 名受训者(94.2%,中位数年龄 38 岁,8 名女性[16.3%])完成了问卷。在培训前,26 名(53.1%)受训者进行了≤50 例独立白内障手术。受训者认为皮质抽吸(平均得分±标准差=3.10±1.14)是最困难的步骤,其次是伤口构建(2.76±1.08)、核前房脱出(2.74±1.23)和晶状体输送(2.51±1.08)。手术野铺巾(1.06±0.242)、麻醉阻滞给药(1.14±0.354)和热凝(1.18±0.441)的评分最低。在回归模型中,皮质抽吸的得分与培训期间进行的>50 例独立手动小切口白内障手术显著呈负相关(P=0.01),但与年龄、性别、眼科工作年限或培训前进行的白内障手术总数无关。
皮质抽吸、伤口构建和核前房脱出对学习手动小切口白内障手术的受训者构成最大挑战,应在培训中予以重视。手术例数是关键步骤感知难度的最强预测因素。
