ABSTRACT
The pre-analytical phase is one of the main sources of non-compliance [NC]. The objective of this work is to evaluate the NCs of the pre-analytical phase at the Microbiology laboratory of Ibn Rochd-Casablanca University Hospital, and to propose preventive solutions. It's a retrospective descriptive study that involved 2028 cases of pre-analytic NC seized over a period of 24-month [August 2016 -July 2018]. This study was based on the exploitation of the computerized data base of our laboratory. From 56143 analysis requests processed during the 24 months, 2028 [3,6%] cases of pre-analytical NC were reported. The most pronounced dysfunctions were noted the pediatric services [15%]. The control of the pre-analytical phase is an important point to reduce sampling nonconformities. The collaboration between the various actors [prescribers, samplers and biologists], the establishment of a NC file, a sampling guide, continuous training and staff awareness are needed to improve the quality of this step
