Control of non-conformities in the pre-analytical phase at the Bacteriology Laboratory of the Ibn Sina University Hospital in Rabat (Morocco).

INTRODUCTION: The errors in the pre-analytic phase are at the origin of 60 to 85% of the errors in the results proceeded from laboratory. AIM: To evaluate the impact of the pre-analytical phase on the received bacteriology samples received at the medical bacteriology laboratory of Ibn Sina UH in Rabat Morocco in order to propose corrective actions. METHODS: A descriptive and quantitative study of the non-conformities of the pre-analytical phase identified in the central laboratory of medical bacteriology of the Ibn Sina hospital in Rabat over a period of 6 months (from January 01 to July 01, 2020). It concerned samples from various clinical services and care units of Ibn Sina Hospital, as well as external samples. In order to act on these various dysfunctions, we used quality tools such as the Pareto chart and from Ishikawa. RESULTS: We counted 424 cases of pre-analytical NC on 14468 samples received to the Central Laboratory of Bacteriology or 2.93%. These are mainly errors of sample identification and patient identity (59.66%), quality and quantity of samples (25.02%) and problem of conditions of transport and packaging (15.32%). CONCLUSION: Its mastery requires firstly, a close collaboration between the various services, prescribers, samplers and biologists and secondly the respect of each stage of this phase by the hospital staff.

Management of biological and infectious risks at the medical bacteriology Laboratory of the Ibn Sina University Hospital in Rabat.

INTRODUCTION: The laboratory of bacteriology is a place with a potential risk and permanent exhibition to biological and infectious hazards caused by the handling of potentially contaminated biological products. AIMS: To evaluate biological and infectious, analyze the circumstances of incidents and accidents and propose a professional risk assessment process (EvRP) to the laboratory with an action plan that can be carried out immediately. METHODS: A descriptive epidemiological cross-sectional study carried out in the medical bacteriology laboratory of the Ibn Sina University Hospital in Rabat over a period of twelve months. It is based on self-questionnaires, observations and interviews with staff. RESULTS: The evaluation showed that the staff of this service is highly exposed. AES constitutes the most important biological risk with 28.6% of the staff but without any declaration. The absence of a referent in health risk management to communicate knowledge of biological and infectious risk to staff. Only 14.3% of staff would be up to date for the vaccination. The absence of a post-exposure biological risk action plan and the design of the tuberculosis laboratory does not comply with risk level 3. CONCLUSION: An action plan and prevention strategies must be implemented and their application is based on numerous national and international regulatory texts.
