Sigmalevels were calculated using bias, coefficient of variationand total allowable error (TEa) ratios of CLIA, Ricos,Rilibak and Turkey.Results: Sigma levels of various tests (CK, amylase, ALT,AST, urea, creatinine, total bilirubin, sodium and chloride)were found to be ≥6 according to different TEa’s,whereas the performance of sodium, potassium and chloridewere unsatisfactory, according to TEa’s of CLIA, Ricosand Rilibak.Conclusion: Since most of our sigma values were found tobe over 3, the analytical performance of clinical chemistrytests was thought to be acceptable and our laboratory canbe regarded as a qualified emergency laboratory.

Abstract

Aim: Emergency department laboratories, besides fromgiving accurate results, should be quick enough in ordernot to delay patient care. Giving fast results doesn’t meanto ignore quality, rather it should always be improved toprevent erroneous results. Six sigma is a modern assessmentof quality which is used to determine the analyticalperformance. Our aim was to evaluate the analyticalperformance of clinical chemistry tests in our emergencydepartment laboratory by using sigma metrics.Materials and methods: Our study was performed byusing the internal and external quality assessment data of13 clinical chemistry tests of emergency laboratory. Sigmalevels were calculated using bias, coefficient of variationand total allowable error (TEa) ratios of CLIA, Ricos,Rilibak and Turkey.Results: Sigma levels of various tests (CK, amylase, ALT,AST, urea, creatinine, total bilirubin, sodium and chloride)were found to be ≥6 according to different TEa’s,whereas the performance of sodium, potassium and chloridewere unsatisfactory, according to TEa’s of CLIA, Ricosand Rilibak.Conclusion: Since most of our sigma values were found tobe over 3, the analytical performance of clinical chemistrytests was thought to be acceptable and our laboratory canbe regarded as a qualified emergency laboratory.

Özet

Amaç: Acil servis laboratuvarları doğru sonuç vermenin yanında hastanın tedavisinde gecikme olmaması için yeterince hızlı olmalıdır. Hızlı sonuç vermek, kaliteyi göz ardı etmek anlamına gelmez aksine yanlış sonuçları önlemek için kalite sürekli geliştirilmelidir. Altı sigma analitik performansı belirlemek için kullanılan modern bir kalite değerlendirmesidir. Amacımız, altı sigma ölçümlerini kullanarak acil servis laboratuarımızdaki klinik kimya testlerinin analitik performansını değerlendirmekti. Materyal metod: Çalışmamız 13 klinik kimya acil laboratuar testinin Temmuz-Aralık 2015 tarihleri arasındaki iç ve dış kalite kontrol verileri kullanarak gerçekleştirildi. Sigma düzeyleri bias, varyasyon katsayısı ve CLIA, Ricos, Rilibak ve Türkiye’nin toplam izin verilebilir hata (TEa) oranları kullanılarak hesaplandı. Sonuç: Farklı TEa’lara göre farklı testlerin (CK, amilaz, ALT, AST, üre, kreatinin, total bilirubin, sodyum ve klor) sigma düzeyleri ≥6 bulunurken; CLIA, Ricos ve Rilibak’ın TEa değerlerine göre sodyum, potasyum ve klorun performansı yetersizdi. Tartışma: Sigma değerlerimizin çoğu 3’ün üzerinde olduğu için, acil laboratuarımızda yapılan klinik kimya testlerinin analitik performansının kabul edilebilir ve laboratuarımızın kaliteli bir acil laboratuvarı olarak nitelendirilebileceği düşünüldü.
