### Security and Intelligent Platforms: AI as a Driver or Change in Healthcare  
In the era of healthcare digitalization, big data and artificial intelligence (AI) are emerging as powerful catalysts for innovation and transformation in the sector. These technologies not only improve security, efficiency, and quality of care, but are also redefining healthcare management. A detailed overview of these innovations and their impacts can be found in Table 5, which summarizes key international research in the field. \begin{table}

Table 5: International Research for Security and Intelligent Platforms. The convergence of big data and AI is opening new frontiers in innovation and predictive analysis in healthcare, introducing intelligent platforms that improve population health management and value-based care. For instance, the integration of a big data and ML platform in Colombia has led to significant improvements in healthcare outcomes and decision making [80]. A notable example is the design of a healthcare knowledge management system in Vietnam [81], which demonstrated how the integration of big data and AI can facilitate the effective management of large volumes of healthcare data. This study highlights the importance of well-designed knowledge management systems for processing and analyzing complex data in healthcare. The use of AI and big data is revolutionizing decision making in healthcare.
