Inpatient hospital settings require access to high-quality blood specimens and durable peripheral intravenous (IV) catheters for patient care. The most common standard-of-care method for acquiring each blood specimen-venipuncture-often results in a non-negligible preanalytical error rate, patient discomfort, and tissue inflammation. In a 2-year, multicenter (23 hospitals) retrospective study, a novel blood collection system that collects blood specimens through existing inpatient IVs without a needle (PIVO, Velano Vascular) was compared with the current standard of care, in regards to its effect on specimen quality and IV catheter longevity. Using the PIVOTM device for blood collection decreased the rate of preanalytical errors by 56% compared with other collection methods, including venipuncture and conventional line draws. In addition, peripheral IV catheters that were used with PIVOTM for blood draws also had a 19% lower rate of replacement compared with those that did not. This is the largest study to date of PIVO use and demonstrates significant quality improvement outcomes compared with the current standard of care in blood collection, providing an opportunity to innovate inpatient hospital care.
住院病房环境需要能够获得高质量的血液标本和耐用的外周静脉（IV）导管，以满足患者护理需求。采集每个血液标本的最常见标准护理方法——静脉穿刺术——通常会导致不可忽视的分析前误差率、患者不适和组织炎症。在一项为期 2 年、多中心（23 家医院）的回顾性研究中，一种新型的血液采集系统通过现有的住院 IV 而无需使用针头（PIVO，Velano Vascular）采集血液标本，与当前的标准护理方法进行了比较，重点关注其对标本质量和 IV 导管寿命的影响。与其他采集方法（包括静脉穿刺术和常规线抽取）相比，使用 PIVOTM 设备进行血液采集可将分析前误差率降低 56%。此外，与未使用 PIVOTM 进行血液采集的外周静脉导管相比，使用 PIVOTM 进行血液采集的导管更换率也降低了 19%。这是迄今为止 PIVO 使用的最大规模研究，与当前的血液采集标准护理相比，其展示了显著的质量改善结果，为创新住院医院护理提供了机会。
