The time difference between manual and electronic double-witnessing procedures, and embryologist perceptions of the EWS.
From 342 witnessing times analyzed (114 EWS, 114 manual, and 114 interruptions to witnesses), the EWS reduced mean (SD) total witnessing time (in seconds) by 91.5 (23.6) for intracytoplasmic sperm injection, 62.0 (17.9) for Day 3 embryo assessment, 58.3 (18.9) for fresh embryo transfer, and 59.4 (13.3) for frozen embryo transfer. This time reduction significantly decreased the overall time required for double-witnessing by 3.1- to 5.2-fold. A survey with 50 embryologists within the laboratory network indicated that most embryologists considered the EWS to improve sample traceability (78.3%), reduce errors in labeling issues (80.4%), and reduce the risk of sample mismatch errors by minimizing disruptions (60.9%). Furthermore, 82.6% thought that visual completion of the EWS dashboard provided peace of mind when leaving work and 84.8% were more confident knowing that all procedures were completed according to the EWS.
An EWS can improve laboratory efficiency by significantly decreasing the time required for witnessing procedures and by minimizing interruptions. The EWS was well perceived by embryologists and laboratory managers and enhanced their confidence and peace of mind with regard to witnessing compliance and safety/accuracy.

人工见证程序与电子双重见证程序之间的时间差，以及胚胎学家对EWS的看法。
在分析的342次见证时间中（114次EWS见证、114次人工见证和114次见证中断），EWS使卵胞浆内单精子注射的平均（标准差）总见证时间（秒）减少了91.5（23.6），第三天胚胎评估减少了62.0（17.9），新鲜胚胎移植减少了58.3（18.9），冷冻胚胎移植减少了59.4（13.3）。时间的减少显著降低了双重见证所需的总时间，降低了3.1至5.2倍。对实验室网络内50名胚胎学家进行的一项调查表明，大多数胚胎学家认为EWS提高了样本可追溯性（78.3%），减少了标签问题中的错误（80.4%），并通过减少干扰降低了样本错配错误的风险（60.9%）。此外，82.6%的人认为EWS仪表板的可视化完成在下班时让人安心，84.8%的人在知道所有程序均根据EWS完成时更有信心。
EWS可通过显著减少见证程序所需时间并减少干扰来提高实验室效率。胚胎学家和实验室管理人员对EWS评价良好，并增强了他们对见证合规性及安全/准确性的信心和安心感。
