Blood Urea Nitrogen to Albumin Ratio for Prognosis in Community Acquired Pneumonia

Background: Community acquired pneumonia causes substantial inpatient morbidity and mortality. This study assessed admission blood urea nitrogen to albumin ratio as a predictor of intensive care support and in-hospital mortality and compared it with CURB-65. Materials and methods: This prospective observational study included 114 adults admitted with community acquired pneumonia to Chittagong Medical College Hospital from July 2024 to September 2025. Discrimination was evaluated using receiver operating characteristic curves, multivariable logistic regression and survival analysis. Results: Intensive care support was required in 42.1% and 12.3% died. Blood urea nitrogen to albumin ratio and CURB-65 independently predicted intensive care support and mortality. For intensive care, area under the curve was 0.966 for the ratio and 0.936 for CURB-65 (p=0.275 for difference). For mortality, respective values were 0.860 and 0.912 (p=0.283). A ratio below 7.87 had 100% negative predictive value for mortality. Survival was lower at values of 7.87 or above (Logrank p<0.001). Conclusion: Admission blood urea nitrogen to albumin ratio is a simple prognostic marker with performance comparable to CURB-65 in hospitalized adults with community acquired pneumonia.><0.001) Conclusion: Admission blood urea nitrogen to albumin ratio is a simple prognostic marker with performance comparable to CURB-65 in hospitalized adults with community acquired pneumonia Chatt Maa Shi Hosp Med Coll J; Vol.25 (2); July 2026; Page 96-100
