Abstract

Amaç: Altı sigma ile analitik testlerin istenilen kalitede olup olmadığı ve kalitenin sayısal değeri görülebilir. Laboratuvarlara sunulan testlerin yöntem kalitesini değerlendirmek, cihazlar arasında yöntem performansını karşılaştırmak, kalite kontrol prosedürlerini yeniden gözden geçirmek konusunda altı sigma metriklerinden faydalanılmaktadır.
Gereç ve Yöntemler: Bu çalışmanın amacı; laboratuvarda aktif çalışılan aynı marka cihazlar arasındaki altı sigma metrikleri ile analitik performansın değerlendirilmesi ve laboratuvar test çalışma hızına göre bu cihazlarda hangi testlerin çalışılıp çalışılmayacağı sorusuna yanıt bulmaktır. Yapılan araştırmada bütün testler ABBOTT marka Architeck c 8000 ve Architeck ci 4000 cihazlarında 6 ay süre ile çalışılmıştır. Glukoz (Glc), üre (BUN), kreatinin (CREA), aspartat aminotransferaz (AST), total kolesterol (CHOL), trigliseritler (Tg), Sodyum (Na), potasyum (K), klor (Cl) parametreleri değerlendirilmiş testlerin sigma değerleri performans yaklaşımına göre hesaplanmış ve cihazlar arasında karşılaştırma yapılmıştır. Toplam kabul edilebilir hata ( TEa), Klinik Laboratuvarları İyileştirme Yasası (CLIA) klavuzlarından alınmıştır. Bias, yeterlilik test verilerine göre belirlenmiştir. Biyokimyasal analitler için varyasyon katsayısı (CV) laboratuvarımızın IQC kayıtlarından elde edilmiştir. Sigma metrikleri (SM) = ( TEa-%Bias )/ %CV formülüne göre hesaplanmıştır
Bulgular: 6 ay boyunca yapılan karşılaştırılmalı takipte ay bazında hangi cihazda çalışılması gereken parametrelerin belirlenmesi değişkenlik göstermiştir. Laboratuvarımızda en fazla çalışılan glucose, urea ve creatinine testlerinin Architeck ci 4000 cihazında sigma değerleri Architeck c8000 cihazından daha düşük olduğu için bu testlerin sadece c8000 cihazında çalışılmasına karar verildi. Elde edilen metriklere göre, 2019 Ekim ayından itibaren başlattığımız çalışmada altı ay sonra elektrolitlerin tek cihazda çalışılmaya başlanması ile sigma değerinde artış tespit edildi.
Sonuç: Altı sigma metrikleri, binlerce test yapılan aynı marka cihazların yöntem performansını değerlendirmede aylık olarak özellikle düşük biyolojik varyasyona sahip testleri takip etmek için kullanılmalıdır.

Abstract

Aim: The aim of this study is that evaluate the analytical performance with six sigma metrics between the same brand devices actively working in the laboratory and answer the question of which tests will be performed on these devices according to the laboratory test working rates.
Material and Methods: In the research, all tests were studied on Abbott brand, Architeck c8000, and Architeck ci4000 model devices for 6 months. Glucose (Glc), blood urea nitrogen (BUN), creatinine (CREA), aspartate aminotransferase (AST), total cholesterol (CHOL), triglycerides (Tg), sodium (Na), potassium (K), chlorine (Cl) parameters were evaluated in the sigma values were calculated according to the performance approach. The comparisons were drew between these two devices. Total allowable error (TEa) is derived from the Clinical Laboratories Improvement Amendments (CLIA) guidelines.
Results: In the comparative follow-up performed for 6 months, the determination of the parameters to be worked on which device on monthly basis varied. Since the sigma values of the glucose, urea and creatinine tests, which are the most studied in our laboratory, are lower in the Architeck ci4000 device than the Architeck c8000 device. It was decided to run these tests only on the Architeck c8000 device. All metrics have been obtained until October 2019. An increase in the sigma value was detected with the start of working of electrolytes on a single device six months later.
Conclusıon: Six sigma metrics should be used monthly to monitor tests with particularly low biological variation to evaluate the method performance of same-brand devices which is used for thousands of tests.
