1998年彰化地區臨床生化外部品管調查

An External Quality-Control Survey for Clinical Biochemistry in Chang-Hua Area in 1998

由彰化區域醫療網於1998年舉辦的外部品質評估計劃是用於評估各實驗室之間對於許多包括葡萄糖、總蛋白、白蛋白、血中尿素氮、肌酸酐、尿酸、膽固醇、三酸甘油酯、天門冬胺酸轉胺基酶以及丙胺酸轉胺基酶等臨床生化檢驗的差異。本次調查分為3階段。各階段調查強調的重點分別是評估、自行改善、以及輔導。在第1階段調查中，彰化地區的醫學實驗室有76.5%（52/68）合格。所有的醫學實驗室中，若以實驗室的等級來分，以教學醫院（100%）（含準醫學中心、區域醫院以及地區教學醫院）的合格率最高，其次為私人檢驗所（88.9%）、地區醫院（66.7%）以及衛生所（58.3%）。第2階段中，接受再測試的14家檢驗室仍有7家不合格。所有在第2階段不合格的單位，於接受第3階段的輔導協助之後都能獲得改善。這些結果顯示，強調調查與輔導並重之外部品質管制計劃的確有助於提昇區域內臨床生化學的檢驗品質。

An external quality assessment scheme was undertaken in 1998 by Chang-Hua Area Medical Network in order to evaluate the interlaboratory differences in many clinical biochemical parameters including glucose, total protein, albumin, blood urea nitrogen, creatinine, uric acid, cholesterol, triacylglyceride, aspartate aminotrans-ferase, and alanine aminotransferase.This inquisition was divided into three phases. The key point of each phase emphasized assessment, improved by oneself, and guidance individually. At the first-stage investigation, the medical laboratories of the Chang-Hua area reached 76.5% (52/68) qualified. Among these medical laboratories, dividing with the grade of the laboratory, the teaching hospital (100%) including would-be medical center, regional hospital. and district teaching hospital had the highest qualified rate, followed by private medical laboratory (88.9%), district hospital (66.7%), and health center (58.3%). At the second stage, fourteen laboratories accepting re-test still had seven of them unqualified. All unqualified institutions at the second stage acquired improvement, after accepting guidance and assistance at the third phase. These results revealed that the external quality control scheme emphasizing equally investigation and guidance was really beneficial to move up the clinical biochemical test, quality inside an area.
