Introduction
Delirium consists of specific impairment of consciousness,
which occurs in elderly patients due to the deterioration of
adaptive abilities and adverse effects of various stimuli. Delirium
worsens the outcome of care of patients, who are hospitalized,
stay in different medical institutions or at home [1-6]. Healthcare
providers should be familiar with the predisposing factors,
diagnostic criteria and methods of managing delirium to be able to
provide better prevention and treatment of the elderly. This will also
lead to a reduction in burdens on health and social care providers
[7,8]. Efficient and proper diagnosis of delirium in elderly patients
is a challenge for general practitioners and nurses. The incidence
of delirium may be underestimated due to diagnostic difficulties,
the specificity of geriatric conditions and insufficient knowledge
among healthcare providers [6].
Discussion
Attempts to estimate the incidence of delirium lead to varying
results, depending on what population is being analyzed. The
incidence of delirium vary also depends on the diagnostic criteria
which have been used [5,6]. In the general geriatric population, the
incidence of delirium does not exceed 2%. According to the recent
meta-analysis, the incidence of delirium in patients on geriatric
and intern wards is 10-31% [6]. It is estimated that the incidence
of delirium among patients in intensive care units, on cardiac
surgery and orthopedics wards is respectively 82%, 46% and 51%.
About 8-17% patients in emergency departments and 22% elderly
patients of nursing homes were diagnosed with delirium [6].
Delirium is often confused with the behavioral and
psychological symptoms of dementia (BPSD), depression and
disorders secondary to “geriatric giants” or somatic illnesses. The
fundamental characteristics of delirium are: a sudden beginning
and impairment of cognitive functions such as fresh memory
disturbances, confusion, or disorientation. Varying symptom
intensity in time is typical.
The diagnostic criteria of delirium are listed by the authors of
the ICD-10 and DSM classifications. Differences in the sensitivity and

Abstract
Delirium consists of a specific impairment of consciousness which occurs in elderly patients due to the physiological deterioration
of adaptive abilities and adverse effects of various stimuli. The incidence of delirium varies between reviewed populations and
may be underestimated due to diagnostic difficulties, the specificity of geriatric conditions and insufficient knowledge among
healthcare providers. Delirium is often confused with the behavioral and psychological symptoms of dementia (BPSD), depression
and disorders secondary to “geriatric giants” or somatic illnesses. The diagnostic criteria of delirium are listed by the authors of ICD-
10 and DSM classifications. For general practitioners and nurses, proper diagnosis of delirium in elderly patients is a challenging
process. Diagnosing delirium by non-qualified healthcare providers is facilitated by numerous psychometric and specialist tools
and scales. The most common are: CAM – the Confusion Assessment Method, MDAS – the Memorial Delirium Assessment Scale;
DOSS – the Delirium Observation Screening Scale and the recently verified tool 4AT–the rapid assessment test for delirium. Proper
diagnosis of delirium warrants optimization of care and stress reduction by formal and informal caregivers.
