Duke Model Score Accuracy as a Predictor of Extended-Spectrum Beta Lactamase (ESBL) Infection in Inpatients

Introduction

The emergence of extended-spectrum beta-lactamase (ESBL) producing bacteria has become a significant concern in the healthcare industry. The overuse of broad-spectrum antibiotics has led to the development of these resistant bacteria, which can cause severe infections in patients. The mortality rate associated with ESBL infections can range from 42% to 100%, making it essential to have an effective method to identify and treat these infections promptly. One such method is the Duke Model Score, which has been gaining attention as a potential predictor of ESBL infections. This article aims to discuss the accuracy of the Duke Model Score as a predictor of ESBL infections in inpatients.

Background

ESBL-producing bacteria are a type of Enterobacteriaceae that are resistant to most antibiotics, including penicillins and cephalosporins. These bacteria produce enzymes that can break down the beta-lactam ring of these antibiotics, rendering them ineffective. The use of broad-spectrum antibiotics has contributed to the emergence of ESBL-producing bacteria, which can cause severe infections in patients. The mortality rate associated with ESBL infections is high, making it essential to have an effective method to identify and treat these infections promptly.

The Duke Model Score

The Duke Model Score is a predictive tool that has been developed to identify patients who are at risk of developing ESBL infections. The score is calculated based on various factors, including the patient's age, sex, and clinical presentation. The score ranges from 0 to 10, with a score of ≥8 indicating a high risk of ESBL infection. The Duke Model Score has been shown to be effective in predicting ESBL infections in various studies.

Study Methodology

This study aimed to evaluate the accuracy of the Duke Model Score as a predictor of ESBL infections in inpatients. The study was conducted at H Adam Malik Hospital Medan between January and August 2014. The researchers calculated the Duke Model scores for all patients who were admitted to the hospital during this period. Bacterial cultures were also performed on identified sources of infection to confirm the presence of ESBL-producing bacteria.

Results

The results of the study showed that the Duke Model Score had a sensitivity of 91.3%, specificity of 82.6%, positive prediction value of 84%, and negative prediction value of 90.5%. The accuracy of the Duke Model score was also evaluated using the ROC curve, which showed that the accuracy reached 93.1% (95% CI: 88.1% - 98.1%; p = 0,0001).

Discussion

The results of this study confirm that the Duke Model Score can function as a reliable predictor of ESBL infections. The high accuracy of the Duke Model score makes it a valuable tool for medical personnel in handling infection patients in hospitals. The adoption of this assessment system in clinical practice can help in making better decisions in antibiotic therapy and reduce mortality associated with resistant bacterial infections.

Conclusion

In conclusion, the Duke Model Score is a reliable predictor of ESBL infections in inpatients. The high accuracy of the Duke Model score makes it a valuable tool for medical personnel in handling infection patients in hospitals. The adoption of this assessment system in clinical practice can help in making better decisions in antibiotic therapy and reduce mortality associated with resistant bacterial infections.

Limitations

This study had some limitations, including the small sample size and the limited number of participating hospitals. Further studies are needed to confirm the results of this study and to evaluate the effectiveness of the Duke Model Score in different clinical settings.

Future Directions

Future studies should aim to evaluate the effectiveness of the Duke Model Score in different clinical settings and to identify the factors that contribute to the development of ESBL infections. Additionally, studies should aim to develop new predictive tools that can identify patients who are at risk of developing ESBL infections.
