The growing use of digital technologies is transforming the way primary health-care services are planned, delivered and monitored, with important implications for community nursing. Tools such as tele-health, mobile health platforms, electronic health records, remote monitoring systems, digital education and artificial intelligence are providing new ways for community nurses to connect with patients and support care beyond conventional health-care settings. This paper critically examines the opportunities, challenges and implications associated with the integration of digital health into community nursing and primary health care. It explores the contribution of digital technologies to health assessment, preventive care, patient education, disease monitoring, follow-up, health communication and coordination of services. These technologies can help overcome geographical barriers, improve continuity of care and encourage patients to participate more actively in managing their health. At the same time, their implementation presents several concerns, including unequal access to digital resources, inadequate digital literacy, poor technological infrastructure, unreliable connectivity, data privacy and cyber security risks, interoperability difficulties and limited training opportunities for nurses. Issues surrounding confidentiality, informed consent, equitable access and the responsible use of artificial intelligence further highlight the need for appropriate ethical and professional safeguards. The paper emphasises that community nurses require relevant digital competencies and institutional support to use technology safely and effectively. Digital health should complement, rather than replace, interpersonal relationships and direct nursing care. A patient-centred, inclusive and ethically responsible approach can enable digital health to strengthen the accessibility, quality, continuity and responsiveness of community nursing and primary health-care services.
