In recent years, the healthcare sector has seen an increase in the application of predictive Modeling. It offers innovative approaches, especially for detecting and managing the diseases early before they manifest. This particular chapter examines the revolutionary effect that predictive modeling has Modeling. Particularly on disease identification and management. This chapter also demonstrates the potential to enhance patient outcomes through timely intervention. A variety of predictive modeling methods are discussed in this chapter; Additionally, this comprises Random Forests and Convolutional Neural Networks (CNN), which are used for cancer diagnosis—related to accurately predicting cardiovascular conditions, Logistic Regression related to forecasting the onset of diabetes, and ARIMA models for monitoring infectious disease spread. The chapter also focuses on many challenges related to data quality, the risk of overfitting, ethical dilemmas, and regulatory compliance. All of these will affect the performance of predictive models specifically. It explores potential advancements in the field, such as developments in machine learning and artificial intelligence. This chapter sheds light on the integrations of multi-omics data and real-time analytics enabled by wearable devices. This chapter also discusses collaborative efforts between the healthcare and research sectors. Synthesizing current knowledge and identifying gaps, this chapter aims to give a comprehensive summary of the potential of predictive modeling and its implications for future research and healthcare practices.
