- W4247016775 abstract "Abstract Background The International Organization for Standardization has recommended monitoring and evaluation of quality laboratory services to ensure accuracy and reliability of diagnoses. The extent of accuracy and reliability of medical laboratory diagnoses in Tanzania has been scarcely documented. Through strengthening laboratory management towards accreditation (SLMTA) program, the researcher evaluated changes in quality indicator. Objective The evaluation aimed at determining the effect of SLMTA program on external quality assessment participation and performance of public laboratories in Iringa and Morogoro in Tanzania. Methodology A comparative laboratory-based cross-sectional design was conducted in Kilosa and Turiani districts in Morogoro region and Iringa Municipal and Mufindi district in Iringa region. External quality assessment (EQA) level of participation was assessed by observing how frequent the laboratory performs PTs, and the number of laboratory tests that are involved in EQA. A total of 178 EQA proficiency malaria, HIV and Haemoglobin (Hb) test results from the public laboratories were gathered by using a checklist. Eighty test results were from SLMTA laboratories (59 from Turiani and 21 from Mafinga lab) while 98 were from non-SLMTA laboratories (63 from Kilosa and 35 from Ngome laboratory). Data were analyzed using software to prepare contingency tables for test sensitivities, specificities, and predictive values. Statistics such as percentage distributions and cross-tabulations were used to analyze data. Findings SLMTA and non- SLMTA labs are participating regularly in EQA for HIV rapid tests (RTs), however, their participation is not regular for malaria and Hb tests. Proficiency test (PT) performance for HIV RTs in SLMTA laboratory category was 64%, while in non-SLMTA was 85%. PT performance for malaria test in non SLMTA was 44%, while it was zero percent in SLMTA lab category. Test performance for Hb was zero percent in SLMTA labs and no datum for Hb PTs available in non SLMTA laboratories. The sensitivity and specificity for HIV RTs was 100% in both laboratory categories (SLMTA and non-SLMTA)." @default.
