ABSTRACT: Background: Antimicrobial Resistance (AMR) has been recognized as a global public health problem of utmost importance that needs to be tackled. Low-income countries such as Uganda have the greatest burden of severe and life-threatening infections and are most likely to suffer more from the spread of untreatable resistant bacteria. Despite the generally increasing trends in AMR, there is hardly any documented data on AMR in orthopedic care. Methods: We analyzed data from the pathogenic isolates from pus and tissue from the laboratory from 2019 to 2023. We calculated the proportions of isolates resistant to commonly used antimicrobial classes. We used the chi-square test for trends to evaluate changes in AMR across the study period. Results: Out of the 286 isolates, 104 (43.5%) were from pus, 112 (46.9%) were from tissue samples and the remaining 9.6% were from different fluid aspirates like synovial fluid. Most of the isolates were from males (64.2%) and aged between 19 and 45 years (46.2%). The distribution of whether the bacteria were gram-positive or negative was relatively equal with 114 (45.2%) being gram-negative and 120 (47.6%) gram-positive. Generally, there was increased AMR across all antibiotics from 2019 to 2021 e.g. for Imipinem, it went from 0% in 2019 to 70.8% in 2021 and for Amoxyclav, it went from 10% in 2019 to 93.2% in 2021. There was a general decline in AMR noted from 2021 to 2023. However, currently, the highest resistance is noted in ceftriaxone (80.0%) and the lowest in Imipinem (11.76%). Conclusion: There is a general decreasing trend in AMR, most probably due to increasing policies governing the use of antibiotics. However, there is still high resistance to commonly used and affordable antibiotics. Continuous monitoring of AMR is still recommended to reduce the AMR problem in Uganda at large through public health policy and planning.
