Analysis and management of the pre-analytical risks in hemostasis

Risk analysis consists in identification, scoring and ranking of risks in order to manage the major risks. The aim of the study is to determine the risk analysis of the pre-analytical step of routine hemostasis in Hematological laboratory of CHU Ibn Rochd-Casablanca, Morocco. The identification of pre-analytical activities of routine hemostasis was extensively realized according to a "by-proccess" methodology. According to "5M" analysis, we identified the risks associated with these activities. Therefore, the scoring of each risk was realized according to «AMDEC» methodology, by the staff of hematological laboratory. Risks were classified according to their severity and the major were identified using "Pareto diagram". Forty eight risks were identified in 15 activities. Identity monitoring (13.7%), pre-analytical storage of samples (13.4%), pre-analytical treatment, including centrifugation (12.9%) and transport to the laboratory (11.3%) represented the activities that exhibited the highest level of risk. Using "Pareto diagram", we retained 19 major risks, related to medical prescription, identity monitoring, transport to the laboratory, pre-analytical treatment of samples and IT processing. Risk analysis allowed the identification of 19 major risks out of 48 identified risks, related to the pre-analytical step of routine hemostasis. These 19 major risks needed a plan to reduce their criticity.
