Background/literature review: The prevalence of agitated behaviors in diffe
rent populations with dementia is between 24% and 98%. Although agitated be
haviors are potentially disruptive, little research attention has been focu
sed on the effects of these behaviors upon nursing staff. The objectives of
this study of demented patients in long-term-care beds at an acute care co
mmunity hospital were to determine the frequency and disruptiveness of agit
ated behaviors; to investigate the associations of patient characteristics
and interventions with the level of agitation; and to explore the burden of
these agitated behaviors on nursing staff. Method: The study sample compri
sed 56 demented patients in the long-term-care unit during the study period
. Twenty-seven staff who cared for these patients during three shifts over
a 2-week period were interviewed to rate the frequency and disruptiveness o
f agitated behaviors using the Cohen-Mansfield Agitation Inventory, and the
burden of care using a modified version of the Zarit Burden Interview. Dat
a on patient characteristics and interventions extracted from the hospital
chart included scores on the Barthel Index and Mini-Mental State Examinatio
n, the use of psychotropic medication, and the use of physical restraints.
Results: Ninety-five percent of the patients with dementia were reported to
have at least one agitated behavior; 75% had at least one moderately disru
ptive behavior. A small group of six patients (11%) had 17 or more disrupti
ve behaviors. The frequency of most behaviors did not vary significantly by
shift. Length of stay on long-term care, Barthel Index score, and the use
of psychotropic medications were significantly associated with the number o
f agitated behaviors. The number of behaviors, their mean frequency, and th
eir mean disruptiveness were all significantly correlated with staff burden
. Discussion: The prevalence of agitated behaviors in patients with dementi
a in long-term-care beds at an acute care hospital is similar to that repor
ted in long-term-care facilities. These behaviors are associated with staff
burden.
