摘要: Background: Misinterpretation of malaria microscopy results can lead to inappropriate case management malaria. The objective this study was assess the quality among health facilities in Hawassa city. A cross - sectional conducted diagnosis city facility laboratories from November 2012 January 2013 Sothern Ethiopia. Validated panel slides were distributed accompanied with a questionnaire that assessed factors related improvement. Operational definitions for correct result and major minor errors outlined. total 51 laboratory professionals 10 surveyed response rate 85%. Results collected data analyzed by SPSS, Win Pepi software. Result: Of 306 examined Sample 1-Sample 6 [S1-S6] only 54% examinations reported correctly. Considering [S1-S4], most common reporting negative positive slide 39/83(47%), species identification error 29/83(35%) density 15/83 (18%). In mixed Plasmodium falciparum/Plasmodium vivax (Pf/Pv) sample, 18% participants made identifying both Pf/Pv species. sample 45(88.2%) scored (no parasites observed) S1-S4, 29 165 densities different reference established each slide. 53% had never participated formal training on microscopy, those who did, more than half trained earlier 2008. All use tap water preparation working Giemsa solution. Conclusion: present assessment revealed poor administration facilities. Therefore, responsible bodies are required improve also provide regular refreshment microscopy. Further similar should be large scale.
