We report outcomes of requests for inpatient phlebotomy procedures from 683 institutions participating in the College of American Pathologists Q-Probes programs. Of the 2,351,643 phlebotomy requests analyzed, 93.2% of venipunctures were successful, 1.6% were unsuccessful, 0.4% were partially successful, and 4.9% were not attempted by the assigned phlebotomist. Administrative inefficiencies prevented the assigned phlebotomist from attempting these venipunctures of which the most frequent reasons were patient unavailability (1.4%), patient transferred or discharged (0.9%), followed by the specimen already collected by someone else (0.7%). These results suggest that performance improvement of phlebotomy services, in general, would achieve the greatest gains by focusing attention to specific processes associated with administrative inefficiencies identified, rather than phlebotomists' technical skills.
我们报告了参与美国病理学家学会Q-Probes项目的683家机构住院静脉穿刺程序申请的结果。在分析的2351643份静脉穿刺申请中，93.2%的静脉穿刺成功，1.6%不成功，0.4%部分成功，4.9%指定的采血人员未尝试。管理效率低下导致指定的采血人员无法尝试这些静脉穿刺，最常见的原因是患者无法到达（1.4%）、患者转院或出院（0.9%），其次是标本已被其他人采集（0.7%）。这些结果表明，总体而言，静脉穿刺服务的性能改进通过关注与已识别的管理效率低下相关的特定流程，而非采血人员的技术技能，将获得最大收益。
