Objective: 

This study seeks to investigate the association between validated psychomotor ability tests and future in-theatre and simulated operative performance.

Summary Background Data: 

Assessments of visuospatial ability, perceptual ability and manual dexterity correlate with simulated operative performance. Data showing the predictive value of such assessments in relation to future performance in the workplace is lacking.

Methods: 

Core surgical residents in Ireland recruited from 2016–2019 participated in assessments of baseline perceptual, visuospatial and psychomotor ability; Pictorial Surface Orientation (PicSOr) testing, digital visuospatial ability testing, and manual dexterity testing. Operative performance was prospectively assessed using the in-theatre Supervised Structured Assessment of Operative Performance (SSAOP) tool, and simulation-based Operative Surgical Skill (OSS) assessments performed over a 2-year core training period. SSAOP assessments were scored using a 15-point checklist and a global 5-point Operative Performance score. OSS assessments were scored using procedure-specific checklists. Univariate correlations and multiple linear regression analyses were used to explore the association between fundamental ability measures and operative performance.

Results: 

A total of 242 residents completed baseline psychomotor ability assessments. Aggregated fundamental ability scores were associated with performance in submitted workplace-based SSAOP assessments using the total checklist score (P=0.002) and overall performance scores (P=0.002), independent of operative experience and centile scores. Aggregated ability scores were also predictive of simulation-based OSS assessment scores on multivariate analysis (P=0.03).

Conclusion: 

This study indicates that visuospatial, psychomotor and perceptual ability testing could be used to indicate future operative performance of surgical residents.

精神运动能力的基线评估与外科受训者未来的手术表现相关一项前瞻性观察队列研究

客观的： 

本研究旨在调查经过验证的精神运动能力测试与未来的手术和模拟手术表现之间的关联。

摘要背景数据： 

视觉空间能力、感知能力和手动灵巧度的评估与模拟手术表现相关。缺乏显示此类评估对未来工作场所表现的预测价值的数据。

方法： 

2016-2019 年招募的爱尔兰核心外科住院医师参与了基线知觉、视觉空间和精神运动能力的评估；图示表面方向 (PicSOr) 测试、数字视觉空间能力测试和手动灵巧度测试。使用战区手术绩效监督结构化评估 (SSAOP) 工具以及在 2 年核心培训期间进行的基于模拟的手术技能 (OSS) 评估对手术绩效进行前瞻性评估。SSAOP 评估使用 15 分清单和全球 5 分操作绩效评分进行评分。OSS 评估使用特定于程序的检查表进行评分。使用单变量相关性和多元线性回归分析来探讨基本能力测量与操作绩效之间的关联。

结果： 

共有 242 名居民完成了基线精神运动能力评估。综合基本能力得分与提交的基于工作场所的 SSAOP 评估中的表现相关，使用总检查表得分 ( P = 0.002) 和总体表现得分 ( P = 0.002)，独立于手术经验和百分位数得分。综合能力得分也可以预测多变量分析中基于模拟的 OSS 评估得分（P = 0.03）。

结论： 

这项研究表明，视觉空间、精神运动和感知能力测试可用于指示外科住院医生未来的手术表现。
