Integrating Internet of Things (IoT) technology into healthcare systems within smart cities represents a transformative advancement in patient monitoring and healthcare delivery. This paper explores the deployment and benefits of IoT-driven healthcare monitoring systems, particularly in urban environments with high population density and diverse health needs. IoT devices enable continuous patient monitoring by facilitating real-time data collection and analysis, leading to improved clinical outcomes and timely interventions. Our findings reveal enhanced patient outcomes, reduced healthcare costs through minimized hospital admissions, and increased operational efficiencies. However, challenges such as data privacy concerns and device interoperability remain critical. We propose solutions, including robust security measures and standardized protocols, to address these challenges. This research underscores the significant potential of IoT-driven healthcare systems in urban settings, advocating for an integrated approach that enhances patient care and promotes health equity in smart city initiatives.
