降低內科病房血液檢體異常率

Reducing The Incidence of Abnormal Blood Specimens In The Medical Ward

血液檢驗為醫療過程的重要項目，採檢與送檢過程任一環節失誤都將影響病人診斷及治療時效性，嚴重則危及病人生命。根據2012年資料統計，本病房每月平均血液檢體異常率為1.91％，遠高出全院之每月平均血液檢體異常率0.92％，分析主要原因為血液採檢認知率低、血液採檢正確性低、血液採檢後超出60分鐘送達檢驗室比率高及真空採血器有效使用率低。透過舉辦血液採檢及送檢教育訓練、跨部門檢討血液採檢與送檢流程、檢討真空採血器設置及推廣使用方法、檢討血液檢體置放及運送設備，使單位血液檢體異常率由1.91％降至0.74％，達成專案改善目標。

Blood specimen collection is a critical step in medical treatment. Any mistake in the collection and transport of blood specimens can adversely affect patient diagnosis, delay treatment, or worse jeopardize patients' lives. Based on the 2012 statistics, the monthly average blood specimen rejection rate was 1.91% in our ward, which was significantly higher than our hospital average (0.92%). After analyzing potential causes of blood specimen errors, the primary causes were established: low cognition of the blood specimen collection, high percentage of specimens did not arrive at laboratory within 60 minutes after collection, and low rate of vacutainer utilization. To address these issues, the project team held several courses on blood specimen collection and transportation, cross-department review on specimen collection and transportation, review the storage and promotion of vacutainer, and review the storage and transportation of blood specimen. After the introduction of this project, our staffs can effectively reduce the rejection rate of blood specimens from 1.91% to 0.74%, successfully reaching the project's intended goal.
