Diagnosis based on clinical grounds alone may lead to misdiagnosis and mistreatment. The objective of this study is to evaluate the performance of malaria microscopy diagnosis in public hospitals of Eastern and Central part Oromia, Ethiopia.Methods: A hospital-based cross-sectional study was conducted from March 2019 to May 2019 in 46 public hospitals of Eastern and Central parts of the Oromia region. Data were collected using structured checklists and pre-prepared known validated positive and negative slides. It was categorized and cleaned by Epi Info version 3.5.1 and analyzed by SPSS version 20 to identify factors associated with poor malaria microscopy diagnosis. The level of agreement was calculated by kappa statistics.Results: From the total of 46 hospitals, 31 (67.39%) had an acceptable quality performance with a cumulative grading score of > 80%. The overall percentage of agreement in detection and species identification was 80.45% (kappa=0.79) and 63.03% (kappa=0. 38). Laboratory professionals who had work experience greater than five years were 10.56 times better in detecting and identifying malaria parasite when compared to those who had work experience less than or equal to five years (AOR [95% CI]=10.56 [1.45– 76.73]). Laboratory professionals who were trained in malaria microscopy diagnosis were 6.12 times reported better quality results than those who were not trained (AOR, % 95CI=6.12 [1.5– 48.13]).Conclusion: The overall agreement of laboratory professionals in detection and species identification was with had substantial and fair agreement with kappa values of 0.79 and 0.38, respectively. Lack of training and low work experience of laboratory professionals were factors associated with malaria microscopy diagnostic performance. Hence, capacitating laboratory professionals is essential to ensure good performance of malaria microscopy which reduces misdiagnosis of malaria parasites and mistreatment of malaria suspected patients.Keywords: malaria diagnosis, level of agreement, mistreatment, Oromia
