A retrospective analysis of a large clinical database was carried out to investigate risk factors that elicit sepsis in people with acute pancreatitis, set up an independent predictive tool-nomogram, and forecast the risk of sepsis in acute pancreatitis people.

Key take away

A novel risk-prediction system can accurately and effectively predict the probability of sepsis in patients with acute pancreatitis, thereby helping to reduce the risk of sepsis and death.

Background

Method

From Medical Information Mart for Intensive Care IV database, 1295 people with acute pancreatitis and 43 variables were extracted. Participants were randomized (in the ratio of 7 : 3) to the training set and the validation set. For testing the distribution of categorical variables, the chi-square test or Fisher’s exact test was utilized. For assessing continuous variables, Student’s t-test was utilized.

For establishing a prognostic model to anticipate sepsis occurrence in acute pancreatitis people, multivariate logistic regression was utilized. For verifying the overall performance of the model, the following indicators were included: decision curve analysis, area under receiver operating characteristic curve, net reclassification improvement, calibration curves, and integrated discrimination improvement.

Result

As per the findings of the multifactor analysis, the independent risk factors were Charlson Comorbidity Index, mean blood pressure, temperature, phosphate, platelet count, albumin, calcium, lactate, urinary output, Glasgow Coma Scale, and sodium.

Notably, all the indicators demonstrated that the prediction performance and clinical profitability of the novel established nomogram were better when compared to other common indicators (including systemic inflammatory response syndrome [SIRS], Bedside index of severity in acute pancreatitis [BISAP], Sequential Organ Failure Assessment [SOFA], and quick-SOFA [qSOFA]).

Conclusion

For early prediction of sepsis in people with acute pancreatitis, the novel risk-prediction scoring system appears to be beneficial. Its application can assist clinicians to formulate personalized management plans for patients, decrease the disease burden, and can contribute to the reasonable allocation of healthcare resources.
