Overall equipment effectiveness (OEE) is a performance indicator that is been used to measure manufacturing productivity. The purpose of this paper is to propose the operating room effectiveness for hospital operating rooms (ORs), adapted from the OEE, to measure performance and identify losses based on lean health-care principles.,The present study is an exploratory, descriptive and applied research work. Literature review, documents of the hospital, observation and interviews with employees of a large university hospital in southern Brazil were analyzed to organize the proposed effectiveness indicator. After that, historical data of the ORs was collected and the usefulness of the indicator was analyzed. The indicator was applied for 10 months and validated with an expert committee from the hospital.,The present study describes an adaptation of a performance indicator to ORs of hospitals, allowing to classify its types of operational losses in a lean health-care context. The application of this indicator and the development of improvement actions to a university hospital, resulted in operational efficiency gains of 12 per cent and estimated annual savings of US$400,000.,ORs are a critical service for hospitals. This paper presents a new way to measure the performance of ORs and identify their main types of wastes. It also shows how to implement it and the potential gains of its application. The main research limitations are related to technical analysis of care data from doctors and nurses involved.,This paper fulfills the need to study how ORs performance can be measured and its operational wastes can be identified. In addition, this paper classifies the planning, performance and quality related losses, which can be used by researchers and practitioners to improve the performance of operation rooms.

手术室有效性：精益医疗绩效指标

整体设备效率 (OEE) 是用于衡量制造生产率的性能指标。本文的目的是根据 OEE 提出医院手术室 (OR) 的手术室有效性，以衡量绩效并识别基于精益医疗原则的损失。本研究是一项探索性、描述性和应用性的研究。研究工作。对文献综述、医院文件、巴西南部一家大型大学医院员工的观察和访谈进行了分析，以组织拟议的有效性指标。之后，收集 OR 的历史数据并分析该指标的有用性。该指标应用 10 个月，并经医院专家委员会验证。本研究描述了绩效指标对医院 OR 的适应性，允许在精益医疗背景下对其运营损失类型进行分类。将该指标应用到大学医院并制定改进措施后，运营效率提高了 12%，估计每年可节省 400,000 美元。手术室是医院的一项关键服务。本文提出了一种衡量 OR 性能并确定其主要废物类型的新方法。它还展示了如何实施它以及其应用的潜在收益。主要研究局限与对相关医生和护士的护理数据的技术分析有关。,本文满足了研究如何衡量手术室绩效和识别其操作浪费的需要。此外，
