1 天前 · Out-of-sequence (OOS) allocation, used by OPOs to limit non-utilization due to excess cold ischemia time, more than doubled in frequency between 2018 and 2022, with median time from first offer to initiation of OOS varying across OPOs from 0 to 47 hours. Increasing rates of organ non-utilization and the observed allocation practice differences ...

在半导体行业中，OOC（Out of Control）和OOS（Out of Specification）是两个重要的质量控制术语，它们代表了产品在生产过程中可能出现的两种不同的异常状态。 定义：OOC代表“失控”，指的是工艺参数或生产过程超出了预定的控制限。 这并不一定意味着产品不合格，而是提醒生产人员需要对工艺参数或过程进行调查和调整，以确保生产过程的稳定性和产品的一致性。 OOC是一个警示，表明过程可能失控，需要进一步的分析和纠正措施。 产品质量下降：工艺参数偏离正常 …

Introduction: Deceased donor liver allocation typically follows a ranked match- run of potential recipients, but organ procurement organizations (OPOs) may deviate in exceptional circumstances with “out-of-sequence” (OOS) matches. We aimed to evaluate trends and factors associated with OOS matches.

Since 2021, the Organ Procurement and Transplantation Network has reported a nearly 10-fold rise in out-of-sequence (OOS) kidney allocation, generating concern and halting development of continuous distribution policies. We report contemporary (2022-2023) practice patterns in OOS allocation using Organ Procurement and Transplantation Network data.

2025年2月25日 · In this manuscript, we review recent changes to kidney allocation, describe the regulatory and policy environment impacting OPO and transplant center behavior, and explore the practice of OOS allocation, considering implications of this practice for utilization and the equitable distribution of organs.
