Predictive value of Shock Index, Reverse Shock Index and Modified Shock Index in GI bleeding patients hospital outcome over 75 years old

Abstract

The aim of the present study was to determine the predictive value of hospital shock outcome, Reverse Shock index and Modified Shock index in GI Bleeding patients older than 5 years.Methods: In this retrospective descriptive cross-sectional study, patients' demographic status including age, sex was documented. Endoscopic results, need for endoscopic intervention and its type, need for surgery and its type, ICU admission, length of stay, need for pack cell, and outcome of discharge and mortality rate were collected. Patients' vital signs, including systolic blood pressure, diastolic blood pressure, heart rate, and respiratory rate, will be recorded. The data entered was analyzed in SPSS version 2 and was used by Chi Square statistical test for qualitative data analysis and independent t test for quantitative variables analysis. Sensitivity and specificity, positive and negative predictive value, positive LR and negative scores were compared with hospital outcome. In all cases the P value less than 0.05 was considered significant.Results: In the ROC graph for SI, RSI, and MSI, the following graph (AUC) is 0.389, 0.662 and 0.339, respectively. In this study, 147 patients entered the study who did not follow the normal distribution by age. The mean age of patients (80.62-82.36, 95% CI) was 81.49 5 5.37 years with mean age of 81 years and age of 75 years. Concerning the value of Shock Index in predicting patient outcome, sensitivity (46 The specificity (95% CI / 80-66 / 30 / CI) was 48.48% and the specificity (79 / 92-23 / 23, 95% CI) was 84.84%. Regarding the value of Reverse Shock Index in predicting patient outcome, it had a sensitivity of 33.33% (95% CI 17/51/96/83, 95% CI 95/42/96/96). has it. Regarding the value of Modified Shock Index in predicting patient outcome, it had a sensitivity of 30.30% (95% CI 95/48/48/59/71) and specificity (95% CI 95/46/46/95). has it.
