Background

Hospital Deaths in Special Care Units: A Growing Concern
Hospital deaths often occur in special care units, especially in Cardiovascular Care Units (CVCU), which covers about 85% of the total death in the hospital. This alarming rate of mortality highlights the need for a reliable and accurate tool to predict patient outcomes in these high-risk units. In this context, M-CARS (Mortality in Cardiovascular Care Unit Risk Score) appears as an important tool for developing a specific death risk prediction model for CVCU. This model is expected to help medical personnel in assessing the risk of patients' mortality more accurately.

The Importance of Accurate Mortality Prediction
Accurate mortality prediction is crucial in CVCU settings, where timely and effective interventions can significantly impact patient outcomes. With the increasing demand for high-quality patient care, hospitals are under pressure to provide evidence-based treatments that minimize mortality rates. M-CARS, as a predictive tool, can help medical professionals identify high-risk patients and tailor treatment strategies accordingly.

Research Purposes

Validating M-CARS in a Real-World Setting
This study aims to test the validity of M-Cars in assessing the mortality of patients treated at CVCU Adam Malik Hospital in Medan. Through this research, it is expected to be able to obtain reliable data to improve patient management in CVCU. By validating M-CARS in a real-world setting, this study can provide valuable insights into the effectiveness of this predictive tool in a high-stakes environment.

Improving Patient Management in CVCU
The primary goal of this study is to improve patient management in CVCU by providing medical professionals with a reliable and accurate tool to assess patient risk. By identifying high-risk patients, medical staff can implement targeted interventions to minimize mortality rates and improve patient outcomes.

Method

Prospective Design and Data Collection
This study uses a prospective design that observes patients treated at CVCU Haji Adam Malik Hospital from September 2021 to January 2022. The validity of the M-Cars Score is tested as a predictor of intra-Hospital mortality. To evaluate the relationship between M-Cars Score and mortality, correlation tests are carried out. If a significant relationship is found, the M-Cars Score cut-off value will be determined using the ROC curve analysis (Receiver Operating Characteristic). Furthermore, diagnostic analysis is carried out to predict mortality during treatment, followed by a hosmer-lemeshow test to assess the compatibility of logistics regression models.

Data Analysis and Validation
The data collected from the prospective study is analyzed using statistical methods to evaluate the validity of M-CARS. The results are then validated using the ROC curve analysis and the Hosmer-Lemeshow test to ensure the accuracy and reliability of the predictive tool.

Research Result

Excellent Discrimination Capabilities
The results showed that M-Cars had excellent discrimination capabilities with an area under the curve (AUC) of 0.93 in predicting intra-Hospital mortality. This indicates that M-CARS is a highly effective tool in predicting patient outcomes in CVCU settings.

Calibration Test Results
The calibration test using Hosmer-Lemeshow produced a R² value of 0.982, with a P-value of 1,516 (P> 0.05). This indicates there is no significant difference between observed and predicted mortality, so that M-Cars can be considered accurate and reliable as a prediction tool.

Conclusion

M-CARS as a Valid and Effective Tool
From the results of this study, it can be concluded that M-CARS is a valid and effective tool for assessing the risk of mortality in CVCU patients in Adam Malik Hospital Medan. With high validity, M-CARS can be an important component in clinical decision making and patient management, and can improve the results of treatment in the heart care unit.

Future Research Directions
Further research is needed to confirm this finding and expand the use of M-Cars in a broader context. With this promising result, hospitals are expected to be able to use M-CARS as a method of evaluating the risk of patient death, as well as improving medical intervention strategies to improve the quality of patient care in CVCU.

Implications for Clinical Practice
The findings of this study have significant implications for clinical practice in CVCU settings. By using M-CARS as a predictive tool, medical professionals can identify high-risk patients and implement targeted interventions to minimize mortality rates. This can lead to improved patient outcomes and better quality of care in CVCU settings.
