This study aimed to determine the prevalence, bacterial isolates, susceptibility profiles, and factors associated with antibiotic resistance at Hoima Regional Referral Hospital, Uganda.Methods: A cross-sectional study was conducted among 216 adult outpatients presenting with productive cough. Sociodemographic, lifestyle, and medical data were obtained using structured questionnaires. Sputum samples were cultured, and antibiotic susceptibility testing was performed using Kirby-Bauer disk diffusion according to Clinical and Laboratory Standards Institute (CLSI) M100 (2022) guidelines. Logistic regression analyses were used to identify factors associated with antibiotic resistance. A p value of < 0.05 was considered statistically significant.Results: Bacterial pathogens were isolated in 139 (64.4%) patients. The most frequent were Streptococcus pneumoniae 57 (40.8%), Staphylococcus aureus 40 (28.6%), Klebsiella pneumoniae 17 (12.2%), and Streptococcus pyogenes 14 (10.2%). Most bacterial isolates were sensitive to imipenem 105 (75.5%), ceftazidime 92 (66.7%), and cefepime 81 (58.5%), while the lowest was to ampicillin 13 (9.5%) and amoxicillin 13 (9.5%). Antibiotic resistance was associated with smoking (aOR = 2.89, 95% CI: 1.074– 7.784, p = 0.036) and prior use of antibiotic (aOR = 2.65, 95% CI: 1.103– 6.369, p = 0.029).Conclusion: Among outpatients with a productive cough at Hoima Regional Referral Hospital, Streptococcus pneumoniae, Staphylococcus aureus were the leading Gram-positive isolates, and Klebsiella pneumoniae was the most common Gram-negative. Gram-negative isolates showed more susceptibility to ceftazidime, and overall susceptibility was more for imipenem, whereas ampicillin and amoxicillin demonstrated very low activity. Antibiotic resistance was significantly associated with smoking and prior use of antibiotic. These findings underscore the need for routine sputum culture and sensitivity testing, and strengthened public health measures to reduce smoking and inappropriate use of antibiotic.Keywords: multidrug resistance, productive cough, Streptococcus pneumoniae, Staphylococcus aureus, Klebsiella pneumoniae, use of antibiotic, smoking, Uganda
