  • Title: Sample Transport Optimization: Mali Pilot Study.
    Author: Kassambara H, Nana ML, Samassa F, Traoré MD.
    Journal: Health Secur; 2020 Jan; 18(S1):S92-S97. PubMed ID: 32004128.
    Abstract:
    In Mali, qualified laboratories for testing of dangerous pathogens are centralized in Bamako. Creating a specimen transport system respecting timeline, specimen quality, biosafety, and biosecurity standards is a challenge. The current ad hoc system that relies on untrained public transport companies carries risks of spoilage, accidental release of pathogens, and delays, which compromise specimen quality. This pilot study aimed to evaluate the effectiveness (ie, timeline, quality of specimen, and cost) of using the trained postal service for sample transportation from district to central level, compared with the current system. The postal service intervention ran from mid-2016 to mid-2017 and covered 3 districts. Data were collected in the same districts during the same period of the preceding year for comparison. In all, 41 specimens were shipped using public transportation and 51 were shipped using the postal service. These included suspected meningitis, measles, yellow fever, and polio samples. Only 46% of samples sent by public transportation were received in Bamako within 72 hours of collection, compared to 71% of samples shipped via the postal service (p < .05). Further, 93% of samples shipped by public transportation arrived in good condition at the receiving laboratory, compared to 98% by postal service. Although cost comparisons were difficult (flat fee vs per-specimen fare), the average cost per specimen was 8 times higher with the postal service. Shipment of specimens from districts to central level using the postal service was feasible and appeared to be faster than public transportation, thus allowing specimen quality to be preserved. Further analysis regarding the most efficient costing mechanism is needed.
