personal belief systems—has become essential to
advancing health literacy. 69
McLeroy’s Ecological and Social Model70 acknowledges
that health is shaped by interrelated factors across multiple
levels, from the individual to the policy domain. Within this
framework, health literacy should be viewed as a
multidimensional process requiring not only the
development of individual competencies but also the
creation of supportive social, institutional, and political
environments that facilitate access to information and
informed decision-making in health.
Since the adoption of the Ottawa Charter, individuals have
increasingly been viewed not merely as recipients but as
decision-makers, managers, co-producers, evaluators, and
agents of change in their own health. 71 At the international
level, recent public policies have reinforced this
perspective. The National Action Plan to Improve Health
Literacy 72 and the Health Literacy Promotion and Education
Strategy 73 outline educational and communication strategies
that highlight the central role of education and
communication in improving healthcare and strengthening
health literacy. The European Commission, through the
European Health Literacy Survey (EHLS), has advanced
integrated policies aimed at monitoring and enhancing
health literacy levels while reducing disparities among
Member States.19
In Portugal, the commitment to health literacy is closely
tied to the evolution of public health policies, which have
shifted from an assistance-based model to one that
recognizes the universal right to health74, as enshrined in
the Health Framework Law.75 Article 12 of this law
highlights the need to integrate health literacy into strategic
areas such as education, labor, and social and
environmental welfare, involving local governments as well
as public, private, and nonprofit entities. This legal
framework ensures that health literacy remains a central
element in all public health decision-making processes.76
The 2019–2021 Health Literacy Action Plan77 and the
current 2023–2030 National Plan for Health Literacy and
Behavioral Sciences78 reinforce the goal of reducing
inequalities and empowering the population to make
informed choices. Several national initiatives promote
access to health information and support healthcare
professional training while encouraging healthy and
inclusive lifestyles. 56,79–81
Aligned with international guidelines 82,83, the 2021–2026
National Patient Safety Plan incorporates health literacy as
a strategy to enhance empowerment and active public
participation in care safety.84–86 Portugal’s decentralized
administrative structure assigns local governments and
intermunicipal entities a central role in promoting health
literacy by managing investments, building partnerships,
and mobilizing stakeholders. 87–90
In sum, health literacy extends beyond the simple
accumulation of knowledge; it constitutes a dynamic and
multifaceted process essential for advancing a more
informed and healthier society. Its progression—from early
health education concepts to a contemporary framework
encompassing cognitive, social, critical, and digital
dimensions—underscores the importance of adopting an
integrated and participatory perspective. Implementing
innovative and comprehensive strategies, supported by
active professional leadership—particularly from nurse
managers—is key to fostering equity, effectiveness, and
sustainability in healthcare systems, transforming them into
spaces where well-being and quality of life are truly
prioritized.8 Therefore, these disparities must be considered
in health policy development and resource allocation to
ensure equity and social justice. 91-93
Health Information Systems
Health literacy, as a dynamic and multidimensional process
that underpins the empowerment of individuals,
professionals, and communities, is put into practice
through health information systems. These systems
function as operational tools for fostering clear
communication, active participation, and informed
decision-making by organizing, protecting, and sharing
clinical data and sensitive indicators—key elements that
define the theoretical models and integrated policies
discussed in the previous section.
In nursing management, this integration is reflected in the
capacity to design personalized care strategies and optimize
resource allocation, ensuring effective, high-quality, and
continuous care in accordance with the Nursing Care
Quality Standards. 12 The integration of these standards
with health information systems has the potential to
identify and overcome barriers to accessing information,
promote measurable, evidence-based practices, and align
care delivery with recognized quality models. 94 Using
health information systems to extract data supports the
development of nursing-sensitive indicators, enhancing the
visibility and value of nursing practice and enabling real-
time monitoring of professional activities. 95-97
The historical evolution of health information systems—
from early electronic records to interoperable, user-
centered platforms—represents a logical progression in
transforming healthcare systems: bridging theory and
practice, advancing excellence, and consolidating health
literacy as a pillar of quality, safety, and innovation.
Initially focused on financial management support, health
information systems gradually incorporated clinical data
through electronic health records, later evolving into
personal health records and, more recently, personal
health information systems. 7,13,98 This modernization has
enabled the structuring and protection of sensitive data
while also promoting interoperability across different
sectors of the healthcare system and driving the
development of initiatives in the field of information and
communication technologies. It is rooted in a foundation
of collaboration and knowledge sharing. 95,99
Studies such as the Portuguese Health Literacy Survey
(HLiteracia em Saúde-PT), conducted in 2014, underscore
the relevance of information sources as essential tools for
improving population health literacy. These findings
emphasize the critical role of information and
communication technologies—particularly health
information systems—in enhancing access to high-quality
