Introduction
The aging population is an inevitable reality that has
significantly shaped healthcare challenges and priorities,
particularly in nursing. According to the National Institute
of Statistics1, projections indicate a concerning ratio of
128,0 to 181,3 older adults per 100 young people, with the
trend expected to double by 2080. This demographic shift
has led to a growing prevalence of chronic diseases (CDs),
affecting 43,9% of the population in Portugal. The World
Health Organization (WHO)2 reported in 2023 that
hypertension (HTN) is the most prevalent
noncommunicable CD, affecting 46% of the global
population, with 1,28 billion adults unaware of their
condition. In Portugal, recent studies3,4 show a 36%
prevalence of HTN, making it one of the leading causes of
mortality. Alarmingly, only 38,9% of those diagnosed with
HTN take medication, and just 28,9% manage to keep their
blood pressure (BP) under control. In hospitals, the
prevalence of HTN among inpatients ranges from 50,5%
to 72%.
HTN is a chronic condition characterized by elevated
blood pressure levels, with values consistently at or above
140/90 mmHg. HTN can be primary (essential) when no
identifiable cause exists or secondary when caused by an
associated disease5,6. Cardiovascular risk refers to the
probability of developing heart and blood vessel diseases,
such as myocardial infarction, stroke, or heart failure. This
risk is influenced by various factors, including HTN,
hypercholesterolemia, diabetes, smoking, obesity, and a
sedentary lifestyle.5,6 Proper management of these
modifiable risk factors can help reduce the likelihood of
severe cardiovascular events.5,6
Given this challenging scenario, there is a need for
innovative and sustainable strategies to address issues
related to aging and chronic diseases. In 2021, the WHO2,
amid the COVID-19 pandemic, outlined the “Global
Strategy on Digital Health,” aiming to promote the
appropriate use of digital resources and adaptable
technologies across nations to tackle major healthcare
challenges and promote equitable access to these resources,
ensuring that no one is excluded5. Similarly, the Shared
Services of the Ministry of Health (SPMS)7, in 2019,
defined Telehealth in the National Strategic Plan for
TeleHealth (PENTS) as a promising solution that includes
Telenursing (TN) (with teleconsultation and
telemonitoring), proposing to shape the future of nursing
care. Despite being significantly driven by the challenges
posed by the COVID-19 pandemic, TN was already a
reality that needs to persist, evolve, and improve
continuously and systematically, regardless of that
exceptional situation.7
Nursing TeleConsultation (TC) can be defined as a
consultation where the nurse, remotely and using various
technologies, assesses a person’s clinical situation and plans
the provision of healthcare, representing a significant
advance in preventive, evaluative, diagnostic, and
interventional approaches7. TeleMonitoring (TM), on the
other hand, involves using technologies to remotely
monitor biometric parameters such as blood pressure, heart
rate, capillary glucose, weight, oximetry, and temperature,
which are transmitted to the care provider8. Nurses should
utilize TM whenever necessary to create nursing diagnoses
and consequently plan interventions7. Technology-based
care models have been widely used and enhanced after the
COVID-19 pandemic, especially in the older adult
population.9
Given the findings of previous systematic reviews that
highlight the effectiveness of TE in reducing HTN values10,
particularly systolic blood pressure, cholesterol levels,
self-efficacy, and therapeutic adherence, this review focuses
on a more specific population group, those aged 65 and
older11. This study aims to map existing evidence on the
effectiveness of TE in managing HTN to prevent and
control cardiovascular risk (CR) in older adults (OA). The
study seeks to contribute significantly to advancing nursing
care by providing important insights into the effective
implementation of this innovative approach in the context
of population aging and chronic diseases.
Methods
This scoping review followed the Joanna Briggs Institute
(JBI) methodology.12 The search strategy and article
analysis adhered to the guidelines for systematic reviews
and meta-analysis extensions, specifically PRISMA-ScR.13
We registered the protocol on the Open Science
Framework (OSF) at Open Science Framework (OSF)
osf.io/76pnm to avoid duplicating scientific evidence.
Selection criteria
The inclusion and exclusion criteria were established based
on the Population, Concept, and Context (PCC)
framework, following the JBI’s guiding principles. We
formulated the research question: What is the contribution
of Nursing Teleconsultation (C) to the prevention and
control of cardiovascular risk in older adults with
hypertension (P) across various contexts (C)?
Population: Individuals aged 65 and older, with or without
controlled hypertension;
Concept: Contributions of teleconsultation in the
prevention and control of HTN and cardiovascular risk
(CR);
Context: Any healthcare setting.
We excluded articles unrelated to the research question or
nursing care, those without defined objectives, and those of
an editorial or opinion nature. This review included studies
with qualitative, quantitative, and mixed designs,
incorporating previous systematic reviews addressing the
