Management of pre-analytical nonconformities at the biochemistry laboratory in Antananarivo in 2019

Management of pre analytical nonconformities within a laboratory is a critical step in ensuring the reliability of results. The objectives of this study are to evaluate the non-compliance of the pre-analytical phase at the Paraclinical Training and Biochemistry Research Unit of the Joseph Ravoahangy Andrianavalona University Hospital Center, to describe in detail the state of play and the progress of this stage. This is a retrospective descriptive study over a period of 5 months from November 01, 2018 to March 31, 2019 within the Paraclinical Training and Biochemistry Research Unit of Joseph Ravoahangy Andrianavalona University Hospital Center. All patient files recorded during this study period have been exploited. Only inpatient records were included in this study. In this study, 5, 71% of pre-analytical non-conformities were recorded. The most frequent non-conformities (recorded 248 times that means 56.88% of the whole nonconformities) were related to the swab or its container, followed by non-conformities related to the prescription sheet (recorded 96 times, that means 22.02%). Pre-analytical non-conformities were the most frequently identified in the surgical intensive care department with 25.24%, followed by the medical service (17.92%). Most of the nonconformities observed were due to preventable human error. However, the laboratory must know how to control nonconformities in order to prevent them and ensure the quality of the analyses.
