RÉSUMÉ
Good management of the pre-analytical phase can avoid a majority of errors in medical laboratory. In this study, we made an inventory of pre-analytical non-compliances [NC] in the parasitology-mycology laboratory of Ibn Rochd University Hospital in Casablanca, in order to identify the causes and to propose corrective actions. It's a retrospective study of the pre-analytical NCs recorded in our laboratory between January and August 2016. There were a total of 546 NCs. 62% related to analysis request, 16% to inadequate sample, 15% to delivery conditions and 3% to sample identification. Each NC was systematically registered on the "KALILAB" quality software. After data analysis, corrective actions were immediately proposed. Otherwise, we organized "quality" meetings, in order to propose preventive actions. Thus, we noticed a decline in the rate of analysis request NCsfrom 10% to 5%, and in those related to inadequate sample from 14% to 7%. Other NCs were relatively stable. Pre-analytical phase is complex because of operator's multiplicity. Biologist must ensure active involvement of laboratory staff in the management process, as well as proposing corrective actions, on a larger scale, in collaboration with various partners
RÉSUMÉ
The act of medical biology is part of a diagnostic, preventive, prognostic and therapeutic approach. The quest for quality must therefore be the essential and constant concern of the biologist and laboratory personnel. This work studied the applicability of Standard 15189 to the parasitological examination of stool, a qualitative method highly dependent on the human factor in addition to technical expertise, a mastery of the working environment and documentation which is essential for the proper execution of the analyzes. The methodology used is a combination of organizational and technical arrangements to master the critical points. A risk analysis and failure modes were carried out in order to detect and prioritize the critical elements to be mastered and to design preventive actions. The results of this ADR have led us to pay attention to the pre-analytical phase, the correct performance of which determines the quality of the analysis; and the analytical phase, the mastery that depends on the competence and empowerment of staff and the accuracy of technical procedures
