Introduction

In the realm of health analysis, the quality and completeness of data play a crucial role in making informed decisions. This study focuses on pre-processing admission data and intensive care unit (ICU) data associated with patient parameters obtained from the Emergency Room (ED). The increasing relevance of this research is evident in the midst of the reappearance of pandemics, which requires a health system to manage data more effectively.

Importance of Pre-Processing Data

Pre-processing data is a crucial first step in medical data analysis. This step includes cleaning data, filling lost values, and coding variables needed for further analysis. In the context of health services, any error or negligence in data processing can be fatal, such as diagnosis or inaccurate errors in patient treatment. Therefore, it is essential to ensure that the data collected is accurate and reliable.

Assessment Models Used

In this study, vital sign data from ED was evaluated using the News2 assessment model, while triage data was considered using the Trews model. The News2 model, or National Early Warning Score, serves to identify patients who need immediate attention on ED. The Trews model, or Triage Early Warning Score, aims to speed up the patient's triage process. The use of these models simultaneously provides a more holistic picture of the condition of the patient to be treated at the ICU.

Pre-Processing Process

The pre-processing process data follows the basic rules of EDPAI, which aims to ensure accurate and reliable data collected. After the pre-processing stage, data results are analyzed to identify risk factors and significant patterns that affect conclusions based on data distribution. The pre-processing process involves several steps, including:

Data Cleaning: Removing missing or inconsistent data
Data Filling: Filling lost values using imputation techniques
Data Coding: Coding variables needed for further analysis

Model Validation

One important aspect of this study is the test validation conducted. This validation is carried out using several performance sizes, such as accuracy, precision, recall, F1-Score, and confusion matrix. It aims to ensure that the model built can not only work well on paper but also in practical applications.

Results

The results showed success in pre-processing data, in which the Random Forest model shows better performance compared to the traditional assessment system in predicting the ICU. This shows that the sophisticated algorithm-based approach can provide a deeper and more accurate insight than the previous method.

Importance of Using the Right Model

One thing to note is the importance of using the right model in predicting transfer needs to ICU. The Random Forest model has been proven to be superior in various situations, especially when the data used has many complex variables and interactions. This model is able to capture patterns that may be missed by a simpler linear model.

Conclusion

By understanding and implementing appropriate pre-processing techniques, hospitals can improve their ability to manage data and, in the end, provide better treatment to patients. This study not only contributes to improving health care systems but also provides useful insights for further research in the field of health analysis.
