Abstract

Objective: Medical laboratories encounter critical obstacles in External Quality Assessment (EQA) practices that are key to assessment of the analytical period. Present study aims to unveil the challenges in nationwide interlaboratory harmonization and suggest practical solutions. Materials and methods: EQA results of 1941 laboratories participating in 18 different EQA-programs between 2010 and 2017 were examined. Standard Deviation Index (SDI) of each program calculated using 801,028 sample data from 24 different clinical chemical tests were used to conduct a process assessment. Results: There is a significant discrepancy in unsatisfactory performance ratio among different EAQ-programs with an average of 3.4% (27,074 cases) between 2010 and 2017 and a decreasing trend (~40–50%) in 7-years. Programs with higher SDI display lower discrepancy rates. Reasons for unaccepted results appear to be data entry errors (8.27–22.2%), material dilution errors (5–11.4%), technical problems (3.76–7.9%); while random or unidentified causes account for a major of 44.9–59.5%. In 7-years, 15.7% reduction was observed in average SDI of all tests. Conclusion: With the launch of national EQA follow-up program, increased awareness of the analytical processes led to a decrease in unaccepted results and variances in the analytical period. Staff training is suggested as a significant measure. In addition, simultaneous assessment of SDI and allowable total error rates would reduce the variation between programs.

Özet

Amaç: Tıbbi Laboratuvarlarda, analitik dönemin değerlendirilmesinde kullanılan Dış Kalite Değerlendirme (DKD) uygulamalarında önemli sorunlar muvcuttur. Bu çalışmada, ulusal çaptaki harmonizasyon çalışmalarındaki sorunların saptanması ve çözüm önerileri sunulması amaçlanmıştır. Gereç ve Yöntem: 2010–2017 yılları TC Sağlık Bakanlığı DKD programı kapsamında, 1941 laboratuvarda, 18 farklı DKD programı ile 24 farklı klinik kimya testine ait toplam 801,028 veri incelenmiş ve süreç değerlendirmesi yapılmıştır. Değerlendirme her programın Standart Deviasyon Indeksine (SDI) göre yapılmıştır. Sonuçlar: 2010–2017 yılları arasında toplam 27,074 (%3,4) yetersiz performans saptanmıştır. Yetersiz sonuç oranlarında yaklaşık %40–50 oranında azalmıştır. DKD programları arasında uygunsuzluk oranlarında farklılıklar saptanmıştır. Özellikle dağılımı geniş olan programlarda uygunsuzluk oranı daha düşüktür. Uygunsuzluk nedenleri incelendiğinde özellikle veri giriş hataları (%8,27–22,2), materyal sulandırma hataları (%5–11,4), teknik problemler (%3,76–7,9), nedenin saptanmadığı ve random olarak değerlendirilen hatalar ise (%44,9–59,5) olarak gözlenmektedir. Yıllara bağlı olarak testlerin SDI dağılımlarında ortalama (%15,7) azalma tespit edilmiştir. Sonuç: DKD programı laboratuvarlarda analitik döneme ait bilincin artışına katkı sağlamıştır. Analitik döneme ait uygunsuzluklarda ve varyasyonlarda azalma tespit edilmiştir. DKD uygunsuzluklarının çözümü konusunda kullanıcıların eğitim eksiklikleri tespit edilmiştir. Bununla ilgili eğitim aktiviteleri gerekliliği farkedilmiştir. Değerlendirmelerin SDI yanı sıra total hata değerleri ile de yapılmasının programlar arasındaki farklılığı azaltacağı tespit edilmiştir.
