High blood pressure in older adults poses significant risks, including cardiovascular disease, stroke, and renal failure; yet, its management is often overlooked. Nurse-led personalised interventions provide essential guidance, helping patients adhere to treatment plans and adopt lifestyle changes, improving outcomes and quality of life. A scoping review of the literature was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR). Six electronic databases were searched systematically (CINAHL, MEDLINE, PsycINFO, EMBASE, Web of Science, and Scopus). Five research studies were included in this review, from five countries (India, Korea, China, Turkey and Thailand). Primary data were synthesised using descriptive and thematic analysis methodology. The five main themes from this review relate to nurse-led empowerment strategies for hypertension management, variability in blood pressure outcomes, the importance of tailored education and counselling, the role of regular follow-ups and support, and environmental support. Overall, nurse-led personalised interventions improve blood pressure management and patient engagement in older adults, highlighting the need for research into their long-term effectiveness and broader applicability.
