Assessment Of Specimen Rejection Rate And Associated Factors Among Samples Referred To Addis Ababa Research And Emergency Management Core Process Laboratory Addis Ababa Ethiopia

Background: Accurate laboratory results are vital for patient safety and improving the medicalrndiagnosis. Most errors occurred in the pre-analytic phase. Improper collection of samples canrnlead to sample rejection. In this case laboratory should establish rejection criteria and followrnthem closely. Specimen rejection may have significant consequences for patients and theirrnclinical management. Thus, understanding the magnitude and taking appropriate action is criticalrnfor quality laboratory service provision.rnObjective: to assess the Specimen rejection rates and associated factors among samples referredrnto the laboratory of Addis Ababa Research and Emergency Management core process.rnMethods: cross sectional study was conducted using both primary and secondary data whichrnassesses the rate and reason of rejection observed from June 01, 2018 to May 30, 2020 G.C.rnAbout 131,909 specimens collected at Addis Ababa Research and Emergency management corernprocess laboratory with in the period of the study was entered and analyzed using SPSS 20.rnResult: a total of 131,909 specimens were sent to central reception of the Addis Ababa publicrnhealth research and Emergence management core processes laboratory. The total rejection raternwas 0.69%, 915. The frequencies of rejected specimens were highest in viral load 35.1%,rnfollowed by clinical chemistry which was 23.4%. The most common reason of rejection wasrnmislabeling, 27.1%, followed by insufficient 15.8%, and clotted 15.1% specimen. Amongrnrejected specimens, 514 specimens were rejected in the first and 401 Specimens were rejected inrnthe second.rnConclusions: The study demonstrated about 0.7% specimen rejection rate. Alongside of thernefforts to minimize laboratory error, this study highlighted a complexity of pre-analytical errorsrnto minimize them. The most commonly rejected specimens were for viral load followed byrnclinical chemistry samples. The most common pre analytical reason for specimens’ rejection wasrnmislabeling, followed by insufficient and clotted specimens.
