Purpose: This study was done to better understand factors affecting care management of older adults with cogni-tive impairments (CI) in acute care settings and to provide a discussion of the literature focusing on educational issues for nurses caring for older adults with CI in acute care settings. Methods: Analysis was done of 26 articles related to management of acute or chronic confusion in older adults in acute care settings, which were published between 2000 and 2012. Results: The theoretical literature outlines nurse-related and organizational-related fac-tors that influence management of dementia or delirium in older adults in acute care settings. These themes offer grounding for further research and the development of education that address the needs of older adults with CI undergoing management for co-morbidity in acute care settings. Conclusion: In the current studies, the emphasis was on the need for education, which has the potential to lead to a significantly positive improvement in RNs’ knowl-edge and attitudes, and the appropriate management and empowerment of family members to participate through the early detection of dementia or delirium in hospitalized older adults with CI. Consequently, facilitating care im-provement for older adults with CI, particularly those with dementia, needs to be given attention in Korean acute care settings.

INTRODUCTION
The growth in the older population, coupled with a
longer life expectancy, is likely to result in an increase
in the incidence of chronic illness, use of hospital serv-
ices and length of hospital stays (Phelan, Borson, Gro-
thaus, Balch, & Larson, 2012). A period of hospitaliza-
tion can have an adverse effect on the health of frail old-
er adults and in particular people with dementia (Phelan
et al., 2012). People with dementia have the highest risk
for developing delirium; the prevalence of delirium in
hospitalized older adults with dementia is found to range
from 59% to 89% (Margiotta, Bianchetti, Ranieri, & Tra-
bucchi, 2006).
There were 495,000 Koreans (8.9% of the population
aged over 65 years) with a diagnosis of dementia in
2011, with an increase of 3.4% in one year (n=469,000
or 5.5%)(Ministry of Health and Welfare, 2011). Currently,
in Korea, approximately one in ten older adults aged
over 65 years is diagnosed with dementia. The propor-
tion of Korean people with dementia is projected to
reach 9.7%(n=750,000) by 2020 as the growth of the
older population continues (Ministry of Health and Wel-
fare, 2011). Despite increasing needs for long-term care
(LTC), the capacity of informal caregiving has been
shrinking due to a decrease in the rate of co-residence
of older parents and adult children alongside the in-
crease in women's employment (Jeong et al., 2005). Al-
though the number of formal LTC facilities and services
has increased following the initiation of the Long-term
Care Insurance Program in July 2008, formal LTC facili-
ties and services to replace or supplement informal care-
giving are in severe shortage. Also, the use of institu-
tionalized care services is often interpreted as children
relinquishing filial duty and older adults being aban-
doned by their adult children (Park, Butcher, & Mass,

for LTC services are hospitalized, even though many of
them do not require medical care (so-called social hos-
pitalization) in Korea (Kim & Choi, 2008). This may re-
sult in an increase in the number of older Korean peo-
ple with dementia or without a diagnosis of dementia
being placed in acute care settings, because Korean so-
ciety perceives institutionalized care services negati-
vely and believe that acute care hospitals provide better
medical services (Lee & Moon, 2010). Acute care nurses
are expected to provide optimum care for these patients
with the best possible outcomes, despite the lack of
suitable ward environments, appropriate staffing or ed-
ucational preparation (Moyle, Borbasi, Wallis, Oloren-
shaw, & Gracia, 2011). However, nurses’ management
of older adults with cognitive impairment (CI) is of great
concern as their task-oriented care in a fast-paced acute
care environment may negatively impact the complexi-
ties of these patients (Moyle et al., 2011). Consequently,
facilitating care improvement for older adults with CI,
particularly those with dementia, needs to be given at-
tention in Korean acute care settings.
This literature review was done to further understand-
ing of factors affecting care management of CI in acute
care settings and to provide a discussion of the literature
focusing on educational issues for nurses caring for old-
er adults with CI in acute care settings.
METHODS
Research literature published in English or Korean is
presented in this paper. Papers included in this review
were chosen according to the following criteria:
1. Inclusion CriteriaMain focus on nurses' management of acute or chro-
nic confusion in older adults (65 years and older) in
acute care settings.
Published in a paper-reviewed journal between 2002
and 2012.
Restricted only to quantitative and qualitative studies.
2. Exclusion Criteria
Main focus was not on an acute care setting.
Published in a non-peer reviewed journal.
3. Search Strategy
Four major databases, the Cumulative Index of Nursing
and Allied Health Literature (CINAHL), Proquest, PsychLit
and Medline were searched, using combinations of
search terms including acute care setting-older adults
with dementia-management-nurses, acute care setting-
older adults with chronic confusion-management-nurses,
acute care setting-older adults with delirium-manage-
ment-nurses, and acute care setting-older adults with
acute confusion-management-nurses. Additional reports
were identified from the reference lists of retrieved pa-
pers. From a summary of the literature and field experi-
ence, a researcher distilled the following definition: acute
care setting is an in-patient adult health medical-surgical
care unit, intensive care unit, or emergency department
in a health care facility (excluding paediatrics, mother/
baby, and psychiatric units). For the relevant literature
search, it was decided to limit the review to acute care
settings that met the criteria in this definition. Table 1
gives an overview of the initial batch of articles (n= 201)
resulting from a search for which there was only a limi-
tation on publication date (2002~2012) and on type of
publication (quantitative study, qualitative study). After
selecting articles based on title and abstract and after re-
moving doubles a total of 44 articles (37 quantitative stu-
dies, 7 qualitative studies) from databases were retained.
A manual search through references and journals yield-
ed 10 more studies, of which only 4 were different. Of

Factors Influencing Management of Cognitive Impairment among Older Adults in Acute Care Settings: A Review of the Literature
the 48 articles retained for the literature review, 26 were
eligible for inclusion. The following discussion of the
findings commences with an identification of the com-
mon themes of factors influencing care management of
CI in older adults in acute care settings followed closely
by a critique of the educational interventions of man-
agement of CI in older adults in an acute care setting.
RESULTS
Common themes gleaned from the literature on fac-
tors affecting the management of CI in older adults as a
result of dementia or delirium in the acute care setting
provides some consensus on patient care. They are div-
ided into two factors; nurse-related and organization-
related. Nurse-related factors include a lack of know-
ledge; personal and professional characteristics; philo-
sophy of care for older adults with CI; and inadequate
assessment and documentation issues. Organizational-
related factors are; acute care culture; priority of safety;
and lack of educational efforts. Such themes offer
grounding for further research and the development of
education that would addresses the needs of older peo-
ple with CI undergoing management for co-morbidity
in acute care settings (Table 2).
1. Nurse-related Factors
1) Nurses’ Knowledge
Nurses’ knowledge about older adults with CI has a
significant influence on nursing practice for the man-
agement of CI in acute care settings (Hamdan-Mansour,
Farhan, Othman, & Yacoub, 2010). Korean nurses’ know-
ledge of delirium, especially its manifestations, were
lower (Choi et al., 2011; Lee et al., 2007). It could be as-
sumed that Korean nurses attribute the cognitive and
behavioral changes of delirium to part of the normal ag-
ing process, and they are not able to differentiate delir-
ium from dementia, because Korean society's expect-
ation is that older adults may become forgetful and
confused. It is likely that delirium is under- or misdiag-
nosed as dementia in Korea, thus preventing acute care
nurses from appropriately managing care to prevent
poor outcomes associated with CI in older adults. A re-
cent study measured registered nurses' (RNs') knowl-
edge on delirium superimposed on dementia (DSD),
using standardized case vignettes and the Mary Starke
Harper Aging Knowledge Exam (MSHAKE) in an Ame-
rican acute care setting (Fick, Kolanowski, & Waller,
2007). It was found that RNs had a high level of general
geropsychiatric nursing knowledge as measured by the
MSHAKE, yet had difficulty recognizing DSD compared
to dementia alone or delirium alone (Fick et al., 2007).
This knowledge level can result in an increase in psy-
chotropic medication use among older adults with DSD
(Fick et al., 2007), which can worsen the condition or
further delay recognition of the problem (Voyer, Ri-
chard, Doucet, & Carmichael, 2009). This indicates that
there is an association between RNs' geropsychiatric
knowledge level and quality of care management. Con-
sequently, an educational intervention developed with
the aim to increase knowledge and then awareness of
delirium in older adults with dementia is an important
consideration to improve recognition and management
of this problem (Fick et al., 2007).
A lack of knowledge contributes to low self-confi-
dence in the ability to manage delirium following as-
sessment (Flagg, Cox, McDowell, Mwose, & Buelow,
2010). Some studies explored the association between
acute care nurses’ knowledge level and self-confidence
in caring for patients with delirium in Korea and the
USA (Choi et al., 2011; Flagg et al., 2010; Yang, 2010).
These studies showed that acute care nurses with defi-
cient knowledge tended to have low confidence in ap-
propriately identifying and managing patients with de-
lirium (Choi et al., 2011; Flagg et al., 2010; Yang, 2010).
In addition to nurses’ knowledge of delirium, one study
found that there were significant differences in self-con-
fidence levels, depending on length of work experience,
status of experience of caring for patients with delirium,
and sufficient number of opportunities for delirium ed-
ucation (Yang, 2010). In this study, acute care nurses
who have worked for more than 5 years, have experi-
enced caring for patients with delirium, or have received
sufficient delirium education were most likely to have
confidence in managing delirium following assessment
(Yang, 2010). This result might be related to nurses’
perception of the importance of delirium in acute care
settings (Flagg et al., 2010). Acute care nurses are not
likely to identify delirium as a common problem and
thus compromise the quality of care provided to pati-
ents at risk for delirium (Flagg et al., 2010). These find-
ings emphasize the need of educational programs to im-
prove nurses’ knowledge.
A study in Japan (Akechi et al., 2010) investigated the
preliminary usefulness of a novel delirium training pro-
gram to improve nurses' self-confidence in caring for
patients with delirium on inpatient wards in a university-
affiliated hospital. This program showed positive results
in improving nurses' self-confidence in caring for pa-

Nurse-related Nurses' knowledge
RNs' lower knowledge level of delirium manifestations attributedthe cognitive and behavioral changes of delirium to part of the normal aging process, and they are not able to differentiate delirium from dementia.
Choi et al., 2011; Lee et al., 2007
RNs' knowledge of DSD measured by standardized care vignettes found that they had difficulty recognizing DSD compared to dementia alone and delirium alone. This knowledge level results in an increase in psychotropic medication use among older adults with DSD.
Fick et al., 2007 Hamdan-Mansour et al., 2010
Nurses' lack ofknowledge tended to result in low confidence in appropriately identifying and managing patients with delirium. They are not likely to identify delirium as a common problem and thus compromise the quality of care provided to patients at risk for delirium.

Yang, 2010
Nurses' personal and professional characteristics
RNs who had a master's degree, had received gerontological education or had perceived the necessity of in-service education for older adults' care, had a higher knowledge level of delirium than those who did not have this education.
Lee et al., 2007
Regardless of educational level, years of experience, or shift worked, orthopedic RNs had difficulty with knowledge related to the recognition of delirium, risk factors, and medications that can contribute to delirium.
Meako et al., 2011
Higher levels of knowledge as a result of education equal more positive attitudes and greater tolerance
Kata et al., 2009; Nilsson et al., 2012
Nurses' negative attitudes attributed delirium to the individual client's personality and not to a physiologic, pathological condition that presents as a disturbance to cognition.
Dahlke & Phinney, 2008; McDonnell & Timmins, 2012
A lack of knowledge and skill led nurses to feel powerless, frustrated and a failure when faced with challenging behaviors thus they increased use of medication and physical restraint to mediate these behaviors
Moyle et al., 2011;Voyer et al., 2009
Nurses' philosophy of care in older adults with CI
Nurses using the healthful perspective were more likely to differentiate between acute and chronic confusion in hospitalized older adults, whereas nurses using the decline perspective were least likely to detect acute confusion.
McCarthy, 2003
Cognitive decline was accepted as normal and contributed to delay or neglect in the assessment of delirium, which results in low rates of recognition of delirium, although delirium is a medical emergency.
Yevchak et al., 2012
Nurses' inadequate assessment and documentation
Nurses superficially assessed their patients' cognition, using subtle questioning and observed behavioral cues, or they only focused on a few questions about orientation due to a lack of knowledge and awareness of cognitive assessment tools.
Choi et al., 2011; Dahlke & Phinney, 2008;
Lee et al., 2007; Yang, 2010;
Yevchak et al., 2012
Nurses depended on reports by family caregivers, the primary carers for hospitalized older adults, who had been asked to watch for symptoms of cognitive decline. Therefore, confused behavior may be overlooked, because family caregivers are not skilled at detecting delirium.
Choi et al., 2011; Lee et al., 2007;
Yang, 2010
With an inaccurate documentation of patients' cognitive status, delirium features weremisinterpreted as dementia or other similar cognitive impairments, adding to the difficulty differentiating delirium from dementia.

Organizational-related
Acute care culture Acute care culture focuses on technological and task-driven care, and thus older adults with dementia are devalued and a holistic approach to care is limited, because of the inconveniences that these patients cause to nurses' routines.
Moyle et al, 2011
Priority of safety For both staff safety and patient security, nurses suggested that chemical or physical restraints were needed to control challenging behaviors in persons with CI, despite the fact that these restraints are risk factors for developing delirium.
Dahlke & Phinney, 2008; Moyle et al., 2011; Park et al., 2006;
Yevchak et al., 2012
Lack of educational efforts
Due to a lack of educational efforts regarding the assessment and management of CI, nurses have not integrated them into their everyday nursing care. As a result, nurses tend to focus more on the patients' physical signs and symptoms rather than their cognitive status.
Moyle et al., 2011; Yang, 2010;
Yevchak et al., 2012
tients with delirium (Akechi et al., 2010). Clinical guide-
lines for nurses should also incorporate a formal educa-
tional program on their use to provide high-quality care
to hospitalized older patients with CI and to improve
acute care nurses' self-confidence (Akechi et al., 2010;
Meako, Thompson, & Cochrane, 2011).
2) Nurses’ Personal and Professional Characteristics
Nurses' personal and professional characteristics seem
to have an influence on the quality of care management
and in particular their knowledge about older adults
with CI (Nilsson, Lindkvist, Rasmussen, & Edvardsson,
2012). Depending on nurses' educational level, attend-
ance at gerontological education course, and percep-
tion of the necessity of in-service education related to
older adults' care, there are differences in the level of
their knowledge of delirium (Lee et al., 2007). In this
study, RNs who had a master's degree, had received
gerontological education or had perceived the necessity
of in-service education for older adults' care had a high-
er level of knowledge of delirium than those who did
not these characteristics (Lee et al., 2007). Meanwhile,
regardless of educational level, years of experience, or
shift worked, orthopedic RNs had difficulty with knowl-
edge related to recognition of delirium, risk factors, and
medications that can contribute to delirium (Meako et
al., 2011).
Nurses’ negative attitudes towards older adults with
CI as well as their lower knowledge level can be an ob-
stacle to the provision of quality care (Dahlke & Phin-
ney, 2008; Kada, Nygaard, Mukesh, & Geitung, 2009;
Nilsson et al., 2012). Previous studies found that nurses
who had negative attitudes were most likely to have
lower levels of education (Kada et al., 2009; Nilsson et
al., 2012). In other words, a higher level of knowledge
as a result of education equals a positive attitude and
greater tolerance (Kada et al., 2009; Nilsson et al., 2012).
Nurses’ negative attitudes attribute delirium to the indi-
vidual client's personality and not to a physiologic, pa-
thological condition that is presented as a disturbance
to cognition (Dahlke & Phinney, 2008). Consequently,
hospitalized older adults with CI are viewed as a bur-
den, because disruptive behaviors are strong predictors
of nurses’ distress that can potentially impact negatively
on patients’ care (Dahlke & Phinney, 2008; McDonnell
& Timmins, 2012). Nurses also experience feelings of
discomfort and incomprehension when dealing with
patients suffering from delirium (Dahlke & Phinney,
2008). Akechi et al., (2010) identified an association be-
tween level of knowledge and skill in relation to cogni-
tion disorders and nurses’ perception of the disorders.
A lack of knowledge and skill led nurses to feel power-
less, frustrated and a failure when faced with challeng-
ing behaviors, so they increased the use of medication
and physical restraint to mediate these behaviors (Voyer
et al., 2009). Consequently, hospitalized older adults
with CI may receive an inferior quality of care in com-
parison to patients without CI, as they are often cared
for by nurses with minimal knowledge or training in this
field (Moyle et al., 2011).
In summary, nurses need more formal education and
training to acquire appropriate knowledge, which can
improve nurses’ self-confidence in assessing and man-
aging the CI of hospitalized older adults as well as pro-
mote positive attitudes (Akechi et al., 2010; McDonnell
& Timmins, 2012; Nilsson et al., 2012). This improved
care practice should result in positive outcomes for
these patients.

3) Nurses’ Philosophy of Care in Older Adults with CI
Nurses’ philosophy of care is frequently based on in-
dividual beliefs rather than on evidence for the delivery
of care (McCarthy, 2003). McCarthy (2003) revealed that
recognition of acute confusion was influenced by the
philosophical orientation of the nurse towards health in
aging. Three distinct perspectives were identified; (1)
decline perspective (regards health in aging as decre-
mental), (2) vulnerable perspective (regards health in
aging as either positive or negative), and (3) healthful
perspective (regards ‘good health’ in aging as normal).
Nurses using the healthful perspective were more likely
to differentiate between acute and chronic confusion in
hospitalized older adults, whereas nurses using the de-
cline perspective were least likely to detect acute con-
fusion (McCarthy, 2003). In addition, the fact that cogni-
tive decline is accepted as normal contributes to delay
or neglect in the assessment of delirium, which can re-
sult in low rates of recognition of delirium, although de-
lirium is a medical emergency (Yevchak et al., 2012). In
older adults with dementia, changes in cognition and
behavior are seldom perceived as important and thus
are more often managed with chemical or physical re-
straints, as a result of being viewed as negative and un-
acceptable (Yevchak et al., 2012). Consequently, em-
phasis should be given to nurses’ views and knowledge
with regard to health in older adults.
4) Nurses’ Inadequate Assessment and Documentation
A lack of knowledge about delirium and its detection
following assessment affects decisions regarding strat-
egies to care for and manage older people in acute care
settings (Yevchak et al., 2012). In fact, nurses are well-
placed to systematically screen for and recognize de-
mentia or delirium in hospitalized older adults because
of their significant presence at the bedside (Fick et al.,
2007). However, the difficulty nurses have in recogniz-
ing delirium (Fick et al., 2007; Yevchak et al., 2012), de-
mentia (Moyle et al., 2011) and DSD (Fick et al., 2007;
Steis & Fick, 2012) has been substantiated.
Acute care nurses superficially assess their patients’
cognition, using subtle questioning and observed be-
havioral cues (Choi et al., 2011; Dahlke & Phinney, 2008;
Lee et al., 2007; Yang, 2010) or they only focus on a few
questions about orientation such as ‘Where are you?’ or
‘Who is your doctor?’ due to a lack of knowledge or
awareness of cognitive assessment tools in the acute
care environment (Yevchak et al., 2012). Also, nurses in
Korea are dependent on reports by family caregivers as
the primary caregivers for hospitalized older adults,
who have been asked to observe the symptoms of cog-
nitive decline (Choi et al., 2011; Lee et al., 2007; Yang,
2010). As a result, confused behavior may be over-
looked, because family caregivers are not skilled at de-
tecting delirium (Yang, 2010). There is a possibility that
hospitalized older adults are managed by nurses' sub-
jective assessment, rather than objective assessment in-
struments.
Currently, nurses are using the term confusion to de-
scribe their patients’ mental status and this is ineffective
in providing quality care management of a patient's
cognitive functioning as it is not a clear term because of
the many different definitions used among health care
professionals (Steis & Fick, 2012). Using this term may
demonstrate that instead of terms prompted by assess-
ment tools such as the Confusion Assessment Method
(CAM) for mental status, nurses limit their assessment to
orientation only and therefore fail to recognize the be-
havioral aspects of delirium in their patients (Steis &
Fick, 2012).
With an inaccurate documentation of patients’ cogni-
tive status, delirium features may be misinterpreted as
dementia or other similar cognitive impairments, add-
ing to the difficulty of discerning delirium from demen-
tia (Fick et al., 2007; Steis & Fick, 2012). Steis and Fick
(2012) reported that American nurses did not recognize
delirium as evidenced by the absence of nurses' nota-
tions of the terms delirium or acute confusion. Also,
nurses documented confused more often in the DSD
group than in the no delirium (ND) group, but there
was no indication that the nurses’ use of the term con-
fusion communicated that the patient was experiencing
delirium (Steis & Fick, 2012). Consequently, it is not
clear whether the term confusion as used by nurses in-
dicates confusion with dementia or delirium as this term
is not consistently defined. As a result, inappropriate
management of delirium or dementia following under-
detection or misdetection leads to an increase in nurs-
ing workload as well as adverse outcomes for older
adults (Pretto et al., 2009).
Therefore, educational efforts are needed to improve
nurses’ ability to detect delirium early as well as to im-
prove their management skills in the busy acute care
environment (Steis & Fick, 2012). Nurses who are caring
for older adults are unsure of how to assess CI, not be-
ing able to differentiate between dementia and delirium
as a result of lack of knowledge and awareness of cog-
nitive assessment tools (Moyle et al., 2011; Yevchak et
al., 2012). Also, they incorrectly assume that a standard
neurological examination is sufficient to identify signs
Vol. 15 No. 3, 2013 211
Factors Influencing Management of Cognitive Impairment among Older Adults in Acute Care Settings: A Review of the Literature
of delirium (Flagg et al., 2010). Nurses need to begin to
use the term delirium as a well-defined and objective la-
bel consistently, in line with their assessment results
rather than the term confusion, which causes misunder-
standings in the process of observation and diagnosis
(Steis & Fick, 2012).
2. Organizational Characteristics of Acute Care
1) Acute Care Culture
In an acute care culture that focuses on technological
and task-driven care, older adults with dementia are de-
valued and a holistic approach to care is limited, be-
cause of the inconveniences that they cause to nurses’
routines (Moyle et al., 2011). As a result, patients with
disruptive behaviors are managed with physical or che-
mical restraints rather than compassionate care to meet
complex care needs (Moyle et al., 2011). Hospitalized
older adults with CI are frequently inadequately as-
sessed and managed based on a medical model of care
delivery that focuses attention solely on the patients'
acute condition (Moyle et al., 2011).
This kind of care also frequently fails to incorporate
the family into the care of hospitalized older adults with
CI (Moyle et al., 2011). Family members as primary
caregivers may be able to recognize a change in pati-
ents’ mental status, even though nurses may have iden-
tified the problem incorrectly (Fick et al., 2007). Acute
care nurses with a better understanding of CI have the
self-confidence to accurately explain delirium presen-
tation and management to patients’ families. This then
empowers family members to participate in patient care
in an effort to reduce the complications associated with
the development of delirium and avoid family suffering
(Flagg et al., 2010).
2) Priority of Safety
Safety is the number one priority identified by nurses
when caring for both chronically or acutely confused
patients. Moyle et al., (2011) reported that Australian
acute care nurses focused on minimizing injury or harm
to a patient, other patients and staff as a consequence of
a lack of understanding about the difference between
dementia and delirium. Despite the importance of per-
son-centered care for people with CI, this care appear-
ed to be overlooked, with resources being allocated
based on the level of risk rather than the level of need
(Moyle et al., 2011).
As a best care practice, person-centered care for older
adults with CI is encouraged to respect the person's past
and focus on ability, rather than disability (Moyle et al.,
2011). However, studies have shown that nurses moved
confused patients' beds close to the nursing station or
into the hallways, or placed patients in geriatric chairs
during the day or at night to restrain movement with lit-
tle perception of the importance of cognitive assess-
ment (Dahlke & Phinney, 2008; Yevchak et al., 2012).
Assessment and care management in such situations
seemed to be task-orientated, rather than about meeting
the psychosocial needs of the confused person (Moyle
et al., 2011). This task-orientated care is commonly used
to prevent falls and to watch over the confused patient
to reduce risks to patient's safety (Dahlke & Phinney,
2008; Yevchak et al., 2012).
For both staff safety and patient security, nurses sug-
gest that chemical or physical restraints are needed to
control challenging behaviors in persons with CI, de-
spite the fact that these restraints are risk factors for de-
veloping delirium (Dahlke & Phinney, 2008; Moyle et
al., 2011; Yevchak et al., 2012). Often older patients
with dementia may be prescribed antipsychotic medi-
cation without recognition or management of the un-
derlying cause of the behavior (Voyer et al., 2009).
Delirium is a cause of disruptive behaviors in many in-
stances (Fick et al., 2007), and inappropriate use of
these medications in hospitalized older adults with de-
mentia may worsen the condition, or further delay rec-
ognition of the problem and thus increase the risk of
death for these patients with dementia (Fick et al., 2007;
Voyer et al., 2009). Safety and the quality of nursing
care provided to hospitalized older adults with demen-
tia at risk for delirium is compromised, and as a result
their lives might be at risk.
As the first line of care management, acute care nurses
need to recognize delirium and use non-pharmacologi-
cal interventions (Fick et al., 2007). However, currently
nurses’ practice is often based on nurses’ experiential
knowledge and trial and error, rather than evidence for
the management of delirium (Yevchak et al., 2012). In
Korea, most acute care nurses are likely to be interested
in the treatment of delirium, despite the importance of
its prevention (Park, Kim, Song, & Kang, 2006). The val-
ue or consequences of currently used non-medication
strategies to manage delirium should be replaced by
evidence-based training and knowledge with practical
guidelines to implement non-pharmacological strategies
(Yevchak et al., 2012).
3) Lack of Educational Efforts
Due to a lack of educational efforts regarding the as-
212 Journal of Korean Gerontological Nursing
Kang, Yun Young
sessment and management of CI, nurses have not in-
tegrated these into their everyday nursing care (Moyle
et al., 2011; Yang, 2010; Yevchak et al., 2012). In acute
care settings, cognitive assessment is not routinely con-
sidered as an important component of standardized nurs-
ing care (Moyle et al., 2011; Yang, 2010; Yevchak et al.,
2012). As a result, nurses tend to focus more on the pa-
tients' physical signs and symptoms rather than their
cognitive status. A study in Jordan confirmed an associ-
ation between knowledge and nursing practice and
found that ICU RNs with more knowledge about delir-
ium were more likely to have a higher level of effective
nursing practice regarding its management (Hamdan-
Mansour et al., 2010).
In Korean acute care settings, there has been little at-
tention given to education or training about the man-
agement of CI. Yang (2010) reported that 24.3 % of
Korean acute care nurses had not received any training
or education on delirium, and 74.9% of those who had
received education on delirium had only a basic under-
standing of the subject. As a result, acute care nurses ex-
perience an elevated level of stress and strain when
managing these patients due to the challenge of im-
plementing highly skilled assessment and care planning
(McDonnell & Timmins, 2012; Yevchak et al., 2012).
This deficit also results in disruptive behaviors because
hospitalized older adults with delirium or dementia do
not have their physical and mental health needs met
(Moyle et al., 2011).
In order to change practices with regard to the ap-
propriate management of dementia or delirium follow-
ing cognitive assessment, the use of cognitive assess-
ment instruments at the bedside should be incorpo-
rated into nursing education to promote more consis-
tent assessment and higher levels of recognition of de-
lirium or dementia (Steis & Fick, 2012). In the end, pro-
viding education to acute care nurses may help to pro-
vide a solution to these problems and can potentially
lead to improved health outcomes and considerable
cost savings.
3. Educational Interventions for Nurses
Studies were reviewed to evaluate the effectiveness
of approaches to education for delirium or dementia
(Akechi et al., 2010; Fick et al., 2011; Lundström et al.,
2005; Lundström et al., 2007; Meako et al., 2011; Naugh-
ton et al., 2005; Pretto et al., 2009; Robinson, Rich, Weit-
zel, Vollmer, & Eden, 2008; Tabet et al., 2005; Voellin-
ger et al., 2011). In these studies, assessment measures
are divided into two measures: nurses’ outcome meas-
ures and patient clinical outcome measures, in order to
assess the effectiveness of the educational intervention.
Despite a number of methodological limitations, it is
reported in some studies that nurses knowledge regard-
ing delirium or dementia improved significantly after
the educational intervention (Meako et al., 2011; Vo-
ellinger et al., 2011) and their performance improved,
showing an increase in nursing assessments for delirium
(Lundström et al., 2007) and the initiation of targeted
management of hospitalized older adults with cognitive
decline (Lundström et al., 2007). With a better under-
standing of assessment and management, delirium was
consequently detected and managed more quickly,
which led to less care needed, especially at night (Pretto
et al., 2009). Meako et al., (2011) investigated the effec-
tiveness of an educational intervention based on evi-
dence to improve orthopedic nurses’ knowledge of
delirium. An educational intervention, given as an
in-service and lecture format with Power Point slides,
was developed on the basis of nationally recommended
guidelines from the American Association of Colleges of
Nursing and the John A. Hartford Foundation Institute
for Geriatric Nursing's Geriatric Nursing Education Con-
sortium in the USA. The presentation contains content
that helps to distinguish between delirium and demen-
tia, recognize risk factors including medications con-
tributing to delirium, and to formulate a management
plan for delirium. Regardless of educational level or
years of experience, a baseline knowledge assessment
confirmed nurses' lack of understanding of delirium.
This baseline knowledge improved significantly follow-
ing the one-hour educational intervention.
In other studies, results also showed positive patient
health care outcomes such as a reduced incidence of
delirium post-intervention (Naughton et al., 2005; Robin-
son et al., 2008; Tabet et al., 2005), fewer complications
during hospitalization and shorter length of stay (Lund-
ström et al., 2007, 2005; Naughton et al., 2005), espe-
cially in people with dementia (Lundström et al., 2007).
However, for the prevention and management of delir-
ium, dementia or DSD, all educational intervention pro-
grams claimed moderate successes (Akechi et al., 2010;
Fick et al., 2011; Lundström et al., 2005, 2007; Meako et
al., 2011; Naughton et al., 2005; Pretto et al., 2009;
Robinson et al., 2008; Tabet et al., 2005; Voellinger et al.,
2011). Table 3 displays studies evaluating the impact of
an educational intervention to improve delirium know-
ledge for acute care.

Factors Influencing Management of Cognitive Impairment among Older Adults in Acute Care Settings: A Review of the Literature
DISCUSSION
In the literature, there are nurse-related and organiza-
tional-related factors affecting the management of CI in
hospitalized older adults. The acute care settings consti-
tute a different care environment, culturally focusing on
technological and task-driven care, and the priority of
safety and lack of educational efforts regarding the as-
sessment and management of CI (Moyle et al., 2011;
Yang, 2010; Yevchak et al., 2012). In the busy acute care
environment, educational efforts are needed to acquire
appropriate knowledge, which can improve nurses'
ability to assess and manage the CI of older adults as
well as promote positive attitudes (Akechi et al., 2010;
McDonnell & Timmins, 2012; Nilsson et al., 2012). This
improved care practice may result in positive outcomes
for these patients. However, little attention has been
paid to enhance acute care nurses' management toward
CI in older adults, although the number of older adults
with dementia admitted to acute care settings has rapid-
ly increased in Korea. Based on an incorrect assumption
that a standard neurological examination is sufficient to
identify delirium, nurses are more likely to focus on ob-
vious medical diagnoses (Flagg et al., 2010). They may
overlook cognitive and behavioral changes in older pa-
tients, which lead to inappropriate management of CI in
acute care settings. The reason may be the result of a
lack of knowledge and awareness of cognitive assess-
ment tools, or not being able to differentiate between
dementia and delirium (Moyle et al., 2011; Yevchak et
al., 2012). Also, the development of a nursing education
program to improve care management for people with
CI is arguably not seen to be a priority in an acute care
setting. In Korea, the majority of acute care settings have
no standardized care protocols to manage dementia or
delirium following cognitive assessment. Although Ko-
rean acute care nurses address the educational needs of
these patients, formal education or training rarely in-
cludes the assessment and management of CI (Park et
al., 2006). Family members as the primary caregivers are
at the bedside 24 hours a day for hospitalized older
adults and they are usually asked to watch for symp-
toms of cognitive decline. However, confused behavior
could be overlooked by professional nurses as they are
bound by Korean social expectations of filial piety, and
the family caregivers are not skilled at detecting delir-
ium (Yang, 2010). It is assumed that family members as
the primary caregivers are not able to manage dementia
or delirium without receiving appropriate education.
Consequently, delirium is often missed in hospita-
lized older adults, and this condition may be mislabeled
as dementia, acute care nurses not being able to distin-
guish dementia from delirium (Fick et al., 2007). As evi-
denced by the absence of nurses’ use of the terms delir-
ium or acute confusion in documentation (Steis & Fick,
2012), nurses' low rates of identifying delirium has been
linked to multiple factors. Identified nurse-related fac-
tors include a lack of knowledge about delirium, or de-
mentia and its detection (Fick et al., 2007). A lack of
awareness among nurses of the clinical importance of
delirium was also found to be linked to undetected de-
lirium (Yevchak et al., 2012). The result can be in an in-
crease in psychotropic medication use among hospi-
talized older adults with delirium, in particular those
with DSD (Fick et al., 2007), which can worsen the con-
dition or further delay recognition of the problem
(Voyer et al., 2009). This factor indicates that there is an
association between nurses' knowledge level and the
quality of care management of CI.
Acute care nurses might lack formal and evidence-
based training, which results in a lower knowledge lev-
el and negative attitudes toward older adults with CI, al-
though they might encounter patients with delirium
who are being managed without clinical care protocols
for CI (Choi et al., 2011; Kada et al., 2009; Lee et al.,
2007; Nilsson et al., 2012). This is especially the case in
Korea where acute care nurses do not have the appro-
priate nursing education in relation to the management
of delirium in hospitalized older adults (Choi et al., 2011;
Lee et al., 2007). Acute care nurses have the potential to
improve patients’ outcomes through the early detection
of dementia or delirium in their patients. In order to im-
prove knowledge and attitudes towards older adults
with or without dementia who have delirium, an educa-
tional intervention needs to be developed to prompt
nurses' recognition and management of these problems
(Fick et al., 2007). With a better understanding of CI,
acute care nurses can empower family members to un-
derstand the symptoms and management of delirium
and therefore enable a reduction in the complications
associated with the development of delirium as well as
additional cost and suffering for patients and family care-
givers (Flagg et al., 2010).
CONCLUSION
This review identifies the potential for nurses’ knowl-
edge deficit of CI as well as how negative attitudes influ-
ence the quality of care management in acute care set-
tings. It also emphasizes the need for education, which
216 Journal of Korean Gerontological Nursing

has the potential to lead to a significantly positive im-
provement in nurses’ knowledge and attitudes and the
appropriate management and empowerment of family
members to participate through the early detection of de-
mentia or delirium in hospitalized older adults with CI.
As a result, it can potentially maximize patients' pos-
itive health outcomes, minimize health care costs, and
decrease the emotional distress of family caregivers.
Studies have shown that nurses’ level of knowledge and
attitudes towards older adults with CI are critical factors
contributing to the quality of care in their patients. Within
the literature, despite some consensus on the manage-
ment of older adults with CI in an acute care setting
(Moyle et al., 2008), knowledge and skills as well as atti-
tudes towards the care of older adults with CI have been
emphasized less, resulting in acute care nurses in Korea,
failing to appreciate the challenges associated with car-
ing for older adults with CI (Choi et al., 2011; Lee et al.,
2007; Yang, 2010). Clinically, differentiation between
dementia and delirium is important as delirium points to
a serious illness and may indicate that the older adult's
life is at risk. Also, dementia is a high risk factor for old-
er adults to develop delirium and causes a more con-
voluted course when coexisting with delirium (Fick et
al., 2007). Consequently, facilitating care improvement
for older adults with CI, particularly those with dementia,
needs to be given attention in Korean acute care
settings.
However, given the relative paucity of studies that test
and report on educational interventions for best man-
agement of older adults with CI, and the dominance of
small scale studies, this review of the literature demon-
strates the need for further research that aims to identify
and evaluate such an educational intervention validation
of CI management. Also, the researcher argues that the
review demonstrates the need for intervention studies
that move beyond the descriptive to an evidence base
for CI management in older adults in acute care settings.
Further research should incorporate the current mana-
gement of older adults with CI into intervention studies
that document the type of intervention used, in suffi-
cient detail to be useful in implementation.
