Introduction
According to the World Health Organization 1, by 2030, it
is estimated that the number of people over 60 years of age
will increase by 34%, from 1 billion in 2019 to 1.4 billion.
By 2050, this population will have doubled to 2.1 billion
worldwide.
In Portugal, demographic aging continues to increase
significantly. According to the 2021 Census2, the population
aging index, an indicator that compares the population aged
65 or over with the population aged 0 to 14, is 182, which
means that there are 182 elderly people for every 100 young
people.
With advancing age, it is expected that there will be changes
typical of the aging process. At the biological level, a variety
of molecular and cellular damage occurs, leading to a gradual
loss in physiological reserves and a functional decline in the
person's intrinsic capacity.3 Muscle weakness, compromised
balance, difficulties in locomotion and worsening of
cognition are some of the changes that occur in aging, and
these contribute to the increased risk of falls in elderly
people.4, 5
A fall can be defined as an unintentional event that results
in the change of position of the individual to a lower
postural level in relation to his/her initial position.6 The
International Council of Nurses (ICN) 7 in addition to
considering that a fall is an “event or episode”, adds that
falling is “a descent from a body from a higher level to a
lower level due to imbalance, fainting or inability to support
weight and stay upright”.
In the elderly, falls are frequent events with possible serious
consequences for the individual and with a significant
economic impact on health institutions. Globally, the
prevalence of falls in elderly people is 26.5%8, with one third
of this population falling at least once a year6, which
contributes to falls being considered the second leading
cause of injuries in the elderly.9
There are several risk factors that contribute to the
occurrence of falls, *and it is consensual to use the
classification of intrinsic and extrinsic factors.
Intrinsic factors are conditions that are related to the client,
such as age, comorbidity, history of previous falls, gait,
visual and auditory impairment, musculoskeletal changes,
and cognitive impairment.10
The extrinsic factors are related to the environment where
the client is inserted. At the hospital level, we highlight acute
illness, delirium, postoperative period, medication, change
of environment, support equipment, bed rest and
immobility, use of inappropriate footwear, lighting of
spaces, lack of knowledge about fall prevention, failure to
communicate between the client and the health
professional.6, 10 In this way, it is noticeable that the hospital
environment is a context where elderly people can present
an extremely high risk of falling.
With regard to the consequences of falls, in addition to
physical injuries, such as fractures and traumatic brain
injuries, it is important to analyse the psychological
consequences, which are harmful for the elderly in the long
term and contribute to a decrease in quality of life. Loss of
confidence and fear of falling are two examples of
psychological consequences and can result in compromised
activity levels, leading to reduced physical function and
social interactions.11
The ICN 7 defines fear as a “negative emotion: feeling
threatened, endangered or upset due to known or unknown
causes, sometimes accompanied by a physiological response
of the fight-or-flight type”.
The fear of falling has been recognized by the scientific
community, since the 1980s, as a health problem in the
elderly. This concept was called ptophobia, in 1982, and is
understood as the phobic reaction to keep standing and
walking, even when there is no neurological or orthopaedic
alteration.12
Subsequently, the fear of falling was defined as a continuous
concern of an individual, when standing or walking, with the
occurrence of falls, compromising the performance of daily
activities.13
Currently, fear of falling can be considered a protective or
pathological condition. On the one hand, fear as a protective
factor will lead the elderly to avoid risky behaviour and seek
to promote safety, either through measures that prevent falls
or through gait adaptations that increase stability. On the
other hand, the pathological fear of falling can lead to a
decline in quality of life and increase the risk of falls by
reducing the activities necessary to maintain self-esteem,
confidence, strength, and balance.5, 14
The fear of falling can cause a loss of confidence in the
ability to perform everyday tasks, leading the elderly to
restrict their daily activities15, social isolation, decline in
physical capacity and loss of independence16, which can
result in changes in mental health, namely the emergence of
depressive and anxious states.17–19 Other psychological
aspects, such as self-efficacy related to falls and self-
perception of health status, are associated with fear of
falling.16
The fear of falling proves to be a risk factor for falls in
elderly people, whether or not they have a history of
previous falls.20 People who are afraid of falling tend not to
be confident in their ability to prevent or avoid falls, which
increases the risk of falling and requires psychotherapeutic
and physical rehabilitation intervention.21
The estimated prevalence of elderly people with fear of
falling is around 36%, which is more evident in people who
have fallen in the last three months.22 In a hospital
environment, the fear of falling in elderly people who are
hospitalized varies between 36 and 83% .17, 23
It is also known that in hospitalized elderly people, the fear
of falling may have a greater influence on functional
recovery than the presence of pain or emotional changes.
Fear of falling also reduces the participation of individuals
in exercises during the rehabilitation process, as they have
functional limitations and reluctance to move.17, 24
The International Classification of Nursing Diagnoses by
NANDA International, Inc. (NANDA-I) 25 presents the
diagnosis “Risk of falls in adults” which is defined as the
“adult susceptibility to experience an event that results in
inadvertent displacement to the ground, floor or other lower
level that may compromise health”.25(p468) Still in this
