Background: - Logistics management information system for health commodities remainedrnpoorly implemented in most of developing countries. These days; however since poorrncommodity management for HIV/AIDS and TB laboratory commodities is leading to stockrnouts and overstocks of these commodities, the need of robust logistics system have gainedrnattention.rnObjectives: - To assess the status of laboratory logistics management information system forrnHIV/AIDS and tuberculosis laboratory commodities in selected public health facilities inrnAddis Ababa.rnMethods: - A cross-sectional descriptive study was conducted to assess the status ofrnlaboratory LMIS used for managing HIV/AIDS and TB laboratory commodities at selectedrnpublic health facilities run by the Addis Ababa Regional Health Bureau (AARHB) andrnFederal Ministry of Health (FMOH) which either distribute HIV/AIDS and TB laboratoryrncommodities to other facilities or provide services such as ART, VCT, PMTCT or TBrnlaboratory services. A stratified random sampling method was used to include a total 43rnfacilities which, were investigated through quantitative methods using structuredrnquestionnaires interviews. The principal person responsible for managing laboratoryrncommodities was interviewed by well trained interviewers using pre-tested questionaries inrneach facility. Focus group discussion with the designated supply chain managers and keyrninformant interviews, using questions adapted from logistics system assessment tool (LSAT),rnwere conducted with central level staff from PFSA, EHNRI and RHB for the qualitativernmethodrnResults: - There exists a well-designed logistics system for laboratory commodities withrntrained pharmacy personnel, distributed standard LMIS formats and established inventoryrncontrol procedures. However, majority of laboratory professionals were not trained in LMIS.rnMajority of the facilities (60.5%) were stocked out for at least one ART monitoring and TBrnlaboratory reagents and the highest stock out rate was for chemistry reagents (direct and totalrnbilirubin reagents). Sixteen facilities (37.2%) had stock outs at the time of visit for at leastrnone ART monitoring and TB laboratory commodity. Expired ART monitoring laboratoryrncommodities were found in 25 (73.5%) of facilities. Fifty percent (50%) of the assessedrnhospitals and 54% of health centers were currently using stock/bin cards for all HIV/AIDSrnxrnand TB laboratory commodities in main pharmacy store, among these only 25% and 20.8%rnof them were updated with accurate information matching with the physical count done at therntime of visit for hospitals and health centers respectively. In hospitals laboratory mini-storesrn37.5% of them uses stock/bin cards for HIV/AIDS and TB laboratory commodities and 25%rnof health centers laboratories starts to use bin cards that were not updated.rnConclusion: - Even though there exists a well designed laboratory LMIS, keeping qualityrnstock/bin cards and LMIS reports were very low. Key ART monitoring laboratoryrncommodities were stock out at many facilities at the day of visit and during the past sixrnmonths. Based on findings, training of laboratory personnels managing laboratoryrncommodities and keeping accurate inventory control procedures were recommended.rnKey words: Logistics management information system, stock outs, laboratory commodities
