Abstract :
Introduction The preanalytical phase is a
crucial step in the analytical process at the Laboratory of
Biochemistry. The control of nonconformities during this
phase is a requirement of the Standard EN ISO 15189
Version 2012. This control is considered one of the most
reliable performance indicators. The objective of our
study was to detect the percentage of annuals differents
nonconformities in order to improve the quality of
reception and results of biochemical examinations.
Materials and Methods This is a cross-sectional,
prospective study of the preanalytical phase in
biochemical analyzes carried out in the Biochemistry
Laboratory during a period from 01/01/2020 to
31/12/2020. The study included all types of samples
requested by clinical services and excluded samples and
prescriptions that did not meet the criteria for good
prescription and for which they were the subject of
nonconformities. Analysis requests are processed at the
reception level, nonconformities will be noted in a
register and entered into the computer system for
analysis.
Results A total of 1,533 nonconformities were identified.
728 (47%) related to the prescription sheet, 796 (52%)
related to the sample and 9 (1%) related to a delivery
error or delay. Regarding the prescription sheet, the
identity mismatch between the collection tube and the
prescription represented the highest proportion with 313
(20%), followed by the absence of the doctor's stamp on
the prescription with 235 (15 %), the absence of the
patient's entry number with 110 (7%), a nonconformity
of the same entry number in two patients with the same
name 44 (3%) and finally the absence of the sheet
prescription with 26 (2%). Regarding the
nonconformities relating to the sample, the highest
proportion was that of the absence of the identity on the
collection tube with 457 (29%), followed by the
nonconformity of the collection tube with 216 (14%), the
absence of the sample to be treated recorded 55 (4%),
the insufficient quantity with 42 (3%) and finally the
broken tube which was of the order of 26 (2%).
Regarding routing issues, it was rated 9 (1%).
Conclusion In view of the results of our study, proposals
can be made, namely the provision of a manual of
parameters and sampling, the continuous training of
medical personnel and the improvement of
communication between the laboratory and the clinical
services
