Background: Conventional healthcare systems rely on episodic care, limiting long-term hypertension management. Digital health technologies are promising alternatives, but evidence remains fragmented. Objective: This scoping review mapped current evidence on digital health technologies for blood pressure monitoring and hypertension management. Methods: Guided by the Arksey and O'Malley framework and PRISMA-ScR guidelines, a comprehensive search was conducted in January 2026 across seven databases for English primary studies published between 2021 and 2026. Results: Twenty-five studies met the inclusion criteria, revealing four technology clusters: Remote Patient Monitoring (RPM), mHealth apps/digital education groups, IoT-enabled wearables, and AI-based systems. These interventions consistently improved blood pressure control, medication adherence, and self-care. However, barriers included patient disengagement, low digital literacy among older adults, privacy/cybersecurity concerns, inadequate system interoperability, and a lack of clear reimbursement policies. Conclusion: Digital health technologies significantly enhance hypertension management. Successful implementation demands human-centered design, supportive policies, interoperable infrastructure, equitable access, and professional well-being alongside technical innovation. Implications for Nursing: Nurses are critical in assessing digital literacy, coordinating remote monitoring, supporting patient self-management, and integrating standardized telenursing into routine hypertension care models.
