Abstract: Aging populations face increasing healthcare challenges, particularly in resource-limited settings such as Brazilian hospitals, where chronic diseases and insufficient infrastructure exacerbate healthcare delivery gaps. This study aimed to develop a decentralized and secure health monitoring system integrating blockchain technology, IoT-enabled wearable devices (Fitbit and BioPatch), and robust encryption algorithms (AES-256 and SHA-256) to address critical issues related to data security, interoperability, and patient monitoring. A sample of 500 elderly patients from two hospitals participated in the study over six months. IoT devices collected real-time health parameters, while blockchain technology ensured secure, immutable, and decentralized data storage and sharing. Advanced encryption protocols safeguarded data integrity and confidentiality during transmission and storage. Statistical analyses, including Chi-Square Test, Paired t-Test, Wilcoxon Signed-Rank Test, and Mann-Whitney U Test, were applied to evaluate security, system performance, and health outcomes. Results indicated zero data breaches, significantly reduced data latency (1.8s vs. 4.2s in traditional systems), improved system uptime (99.6%), and enhanced data retrieval success rate (99.8%). Health outcomes improved with a 60% reduction in emergency health interventions (from 315 to 124 cases). Satisfaction scores among patients (4.7/5) and healthcare providers (4.8/5) reflected high acceptance and usability. While the system demonstrated strong potential, challenges remain regarding scalability, deployment costs, and digital literacy among users. Practical recommendations include investment in scalable blockchain infrastructure, cost-sharing through public-private partnerships, AI integration for predictive analytics, and digital literacy training programs. This study concludes that blockchain-integrated IoT health monitoring systems provide a secure, reliable, and scalable solution for elderly healthcare management, with significant implications for healthcare policy and practice in developing regions.
