Background: Supply chain management process allows the right laboratory commodities in thernright quantities in the right condition delivered to the right place at the right time for the rightrncost. Poor management of laboratory equipment, reagents and other suppliers with recurrentrnstock-outs of reagents, frequent equipment breakdown was a major gap in ensuring quality andrnuninterrupted testing leading to patient dissatisfaction, and it needs more attention to strength andrnimprove supply chain management practices. rnObjective: This study aimed to assess supply chain management of laboratory equipment,rnreagents, supplies and its impact on the quality of laboratory services of public hospitals in AddisrnAbaba, Ethiopia.rnMethods: The study employed a quantitative design using a hypothesis testing approach tornidentify the effect of supply chain management of laboratory equipment, supplies, reagents,rnconsumables on quality of laboratory services. 169 questioners were distributed to employeesrnworking in laboratory divided on thirteen (13) public hospitals found in Addis Ababa, fromrnFebruary 2019 to May 2019 using questioner and observational checklist. After data was enteredrnto SPSS 23, frequency, percentage was computed, presented using tables and graphs, and Binaryrnlogistic regression was analyzed to see the effect of the independent variables with dependentrnvariables by using Odds Ratio (OR) with 95% confidence interval with p-value of less than 0.05. rnResult: The 61.5% (n=8/13)of public health facilities had policy criteria for selection andrnprocurement of laboratory commodities, 51.3% (n=7/13) of the laboratory stores met thernstandard storage criteriaâ€™s which were the good features of supply chain management practices,rnwhile in 77% (n=10/13) of public hospitals laboratory staffs had no access to training particularlyrnrelated to supply chain management, during the last six months and visit time 69.2% (n=9/12)rnpublic hospitals encountered stock out reagents and controls of coagulation, hormonal, chemistryrntests, 69.2% (n=9/13) encountered suppliers misbehave during procurement, 61.5% (n=8/12)rnpublic hospital laboratory had no work planned budgetary projections and in the 61.5% (n=8/12)rnpublic hospitals the laboratory professionals were not involved in the procurement process.rn73.5% (n=117/159) of participants indicated that the overall extent of supply chain managementrnof public hospital laboratories were not adequately practiced. 70.4 %( n=112/159), 73.6%rn(n=117/159), 69.2% (n=110/159), 74.8% (n=119/159), 79.9% (n=127/159) of participantsrnindicated there was no adequate practice of logistics management, supplier relation management, rn rnix rn rncustomer relationship management, information sharing, and order fulfillment respectively. Inrncase of quality service provision in 84.6% (n=11/13) of public hospitals there was lack ofrnvaccine against Hepatitis B and 84.6% (n=11/13) of public hospital laboratories did not monitorrnquality control for each tests on daily bases. Findings also revealed that 56% (n=89/159) ofrnlaboratory professionals indicated that their laboratory did not provide timely services as per tornpreset turnaround times, 57.9 % (n=92/159) of laboratory professionals indicated that theirrnlaboratory did not provide reliable services, 63.3 % (n=101/159) of laboratory professionalsrnindicated that laboratory service provision was not as per to safety requirements. Logisticrnregression showed the difference in supply chain management and quality due to educationalrnlevel, degree (AOR=0.25(0.07-0.84)), masters (AOR=0.19(0.04-0.86)). Practicing logisticsrnmanagement (AOR=3.32, 95% CI= (1.4-8.0) and order fulfillment (AOR=3.56, 95 % CI=(1.329.56)rnwerernrnfound 3.32 and 3.56 times more likely to provide the quality laboratory service thanrnthose which did not practice it respectively.rnConclusion: Based on the study findings we can conclude that, the supply chain managementrnpractices and provision of quality laboratory at public hospitals needs improvement to meet thernstandard. Recruiting employee with higher education, practicing logistics management and orderrnfulfillment led to success in the provision of quality laboratory services. From observation, ourrnfinding showed lack of training related to supply chain management, non-involvements ofrnlaboratory professionals in purchasing, stock out of reagents and controls, supplierâ€™srnmisbehaving and absence of HB vaccine were major gaps in provision of quality of laboratoryrnservices.
