Abstract
BACKGROUND
Hajibandeh index (HI), derived from combined levels of C-reactive protein, lactate, neutrophils, lymphocytes and albumin, is a modern predictor of peritoneal contamination and mortality in patients with acute abdominal pathology.
AIM
To validate the performance of HI in predicting the presence and nature of peritoneal contamination in patients with acute abdominal pathology in a larger cohort study and to synthesis evidence in a systematic review and meta-analysis.
METHODS
The STROBE guidelines and the PRISMA statement standards were followed to conduct a cohort study (ChiCTR2200056183) and a meta-analysis (CRD42022306018), respectively. All adult patients undergoing emergency laparotomy for acute abdominal pathology were eligible. The accuracy of the HI was evaluated using receiver operating characteristic (ROC) curve analysis in the cohort study and using weighted summary area under the curve (AUC) under the fixed and random effects modelling in the meta-analysis. The Quality Assessment of Diagnostic Accuracy Studies 2 criteria were used for methodological quality assessment of the included studies.
RESULTS
A total of 1437 patients were included (700 from the cohort study and 737 from the literature search). ROC curve analysis of the cohort study showed that the AUC of HI for presence of contamination, purulent contamination and feculent contamination were 0.79 [95% confidence interval (CI): 0.76-0.82, P < 0.0001], 0.76 (95%CI: 0.72-0.80, P < 0.0001), and 0.83 (95%CI: 0.79-0.86, P < 0.0001), respectively. The meta-analysis showed that the pooled AUC of HI for presence of contamination, purulent contamination and feculent contamination were 0.79 (95%CI: 0.75-0.83), 0.78 (95%CI: 0.74-0.81), and 0.80 (95%CI: 0.77-0.83), respectively.
CONCLUSION
The HI is a strong and accurate predictor of intraperitoneal contamination. Although the available evidence is robust, it is limited to the studies conducted by our evidence synthesis group. We encourage other researchers to validate performance of HI in predicting the presence of intraperitoneal contamination and more importantly in predicting mortality following emergency laparotomy.
