Abstract

PURPOSE
This study examined the availability of the age shock index in an assessment of high risk patients with acute cholecystitis in an emergency department.
METHODS
Consecutive data of patients who presented to the emergency department with acute cholecystitis during the period, January 2012 and March 2017, were reviewed retrospectively. Univariate and multivariate analyses were performed to determine the relationship between the severity of acute cholecystitis and the clinical factors.
RESULTS
A total of 242 patients with acute cholecystitis were included in this study. From univariate analyses, age, Murphy's sign, symptom duration, heart rate, respiratory rate, age shock index, hypertension, diabetes, leukocytes, C-reactive protein and blood urea nitrogen were found to be related to the severity of acute cholecystitis. From multivariate analysis, the symptom duration (OR, 4.271; 95% CI, 2.672-6.827), respiratory rate (OR, 1.482; 95% CI, 1.189-1.847), age shock index (OR, 1.609; 95% CI, 1.060-2.442, 10-point interval), leukocytes (OR, 1.283; 95% CI, 1.156-1.424), and diabetes (OR, 4.590; 95% CI, 1.507-13.976) had a positive relationship with the severity of acute cholecystitis.
CONCLUSION
The age shock index, which is calculated easily using the patient's age, heart rate, and systolic blood pressure, can be a predicting factor of severe acute cholecystitis in an emergency department.
