Impact of Solid Organ Injury Severity on Critical Care Resource Use and Clinical Outcomes in Blunt Abdominal Trauma Patients:A Schematic Assessment

Background: Solid organ injuries during blunt abdominal trauma (BAT) have a major effect on patient outcomes. This systematic review and meta-analysis aimed to evaluate the impact of solid organ injury severity on critical-care resource use, non-operative management failure, and mortality in patients with blunt abdominal trauma. Methodology: Research was conducted in PubMed, Scopus, Web of Science, and Google Scholar until November 2025, and included any of the studies involving adult patients and reporting blunt liver, spleen, or kidney injuries. Articles that presented odds ratios (ORs) or adequate information on ICU admission, NOM failure, or mortality were incorporated. A random-effects model was employed for the meta-analyses, using inverse-variance weighting. ORs with 95% confidence interval (CI) were pooled, and I2 measured the heterogeneity. The Newcastle-Ottawa scale was used to assess the risk of bias, and the certainty of evidence was estimated with GRADE. Sensitivity and subgroup analysis have been conducted to examine the soundness of results. Results: 12 articles were included. Solid organ injuries of high grade were linked to augmented ICU admission/critical-care use (OR 2.95, 95% CI = 1.09-7.99, I2 =92%). There were no statistically significant differences in NOM failure (OR 0.53, 95% CI = 0.06-4.58, I2 =89%) and mortality (OR 1.48, 95% CI = 0.67-3.28, I2 =78%). The overall level of evidence was moderate. Conclusion: Solid organ injury severity is a predictor of critical-care resource use, whereas there is a less predictable effect on NOM failure and mortality. Individual management according to the grade of an injury, and patients are advised.
