Abstract

Objective

This study presents the results of a surgical instrument tray optimization process implemented across all surgical specialties within the largest university hospital in Denmark.

Methods

Data was extracted from a comprehensive instrument optimization process including all Operating Rooms at Aarhus University Hospital. Adopting a holistic perspective, the optimization process, involved aligning instrument trays across various surgical specialties. This included: a) Reduction in number of instruments, b) Consolidation or separation of trays, c) Modularization - introducing modular trays for specific purposes, and d) Standardization - standardizing commonly used instruments across specialties. Instruments per tray, total number of instruments, and changes in the number of trays were compared against existing tray contents to identify discipline-specific changes.

Results

Some specialties made substantial alterations to tray structures, while others primarily reduced number of instruments in existing trays. Across all specialties, optimization resulted in 17 % decrease in number of tray types (p = 0.01, 95%CI:1.0–6.8), 1 % increase in total number of trays (p = 0.36, 95%CI:-11.9–4.8), 18 % decrease in number of instruments per tray (p = 0.0002, 95%CI: 3.2–7.6) and 16 % reduction in total number of instruments for all specialties (p < 0.0001, 95%CI:404–758).

Conclusion

This study underscores complexity of instrument tray design. The approach employed at Aarhus University Hospital, involving interdisciplinary experts in an iterative design process, demonstrated the feasibility of redesigning instrument trays with significant reduction in content. Additionally, data suggests that reducing the number of instruments could lead to a decrease in workload within the Central Sterile Supply Specialty. This presents opportunity to minimize wasted resources and streamlining cleaning processes for unused instruments.

一家大学医院的手术器械托盘优化流程：全面概述

本研究介绍了在丹麦最大的大学医院内所有外科专科实施的手术器械托盘优化流程的结果。方法从包括奥胡斯大学医院所有手术室在内的全面器械优化流程中提取数据。从整体角度看，优化过程涉及调整各外科专科的器械盘。这包括：a) 减少器械数量；b) 合并或分离托盘；c) 模块化 - 为特定用途引入模块化托盘；d) 标准化 - 将各专科常用器械标准化。将每个托盘中的器械、器械总数以及托盘数量的变化与现有托盘内容进行比较，以确定特定学科的变化。在所有专科中，优化后的托盘类型数量减少了 17%（p = 0.01，95%CI:1.0-6.8），托盘总数增加了 1%（p = 0.36，95%CI:-11.9-4.8），每个托盘的器械数量减少了 18%（p = 0.0002，95%CI：3.2-7.6），所有专科的器械总数减少了 16%（p < 0.0001，95%CI：404-758）。奥胡斯大学医院采用的方法让跨学科专家参与迭代设计过程，证明了重新设计器械盘并显著减少内容的可行性。此外，数据表明，减少器械数量可减少中央消毒供应专业的工作量。这为最大限度地减少资源浪费和简化未使用器械的清洁流程提供了机会。
