Can changes in ward routines affect the severity of dementia? A controlled prospective study

High versus Low Density Special Care Units: Impact on the Behaviour of Elderly Residents with Dementia

L'ouverture d'une nouvelle unité de soins spéciaux a permis d'étudier l'effet de la densité sociale réduite (moins de résidents) et de la densité spatiale (plus d'espace par personne) sur le comportement de résidents avec démence. Deux groupes (N = 64) ont été observés pendant trois périodes espacées de six mois chacune. Tel que théorisé, il y a eu plus d'amélioration dans le comportement perturbateur et non perturbateur du groupe expérimental (passant de haute à basse densité) par rapport au groupe de comparaison (haute densité constante). Les résultats indiquent que la densité de l'unité résidentielle est un déterminant important pour le comportement des résidents âgés avec démence.

Continuity in the midst of change: behaviors of residents relocated from a nursing home environment to small households

A time-sampling procedure was used to observe behaviors of 22 long-term-care residents with dementia (Mini-Mental State Exam median, 11.94; range 0-23) in public areas before and after relocation from a traditional nursing home environment to 2 small household units. Two trained observers noted the occurrence of 19 social behaviors (14 verbal, 5 nonverbal) in which the resident intentionally interacted with another person. Another 19 nonsocial behaviors (16 active, 3 passive) were also coded. Analysis by t tests of 6 groupings of behaviors showed no significant differences before and after relocation, with the exception of nonverbal social interactions. Overall, residents showed consistency in both social and nonsocial behaviors. Results are interpreted in light of personal, social, and environmental continuity despite the many changes associated with the relocation.

"Individualised care" from patients', nurses' and relatives' perspective--a review of the literature

This paper provides an overview of the empirical research literature on individualised care. It offers a description of the methods that have been used in studies of individualised care over the years, and then discusses the meaning and realisation of individualised care from patients', nurses' and relatives' points of view in order to highlight needs for further research. The review focuses on empirical articles retrieved from the MEDLINE database published between 1973 and June 1999. It draws attention to the complexity of individualised care, which at first sight may look like a relatively straightforward nursing activity. It is shown that a wide range of methods have been used to study individualised care in the current literature. There is a lack of research where patients' experiences of the individuality of care in hospital settings are concerned.

The therapeutic design of environments for people with dementia: a review of the empirical research

Design of the physical environment is increasingly recognized as an important aid in caring for people with dementia. This article reviews the empirical research on design and dementia, including research concerning facility planning (relocation, respite and day care, special care units, group size), research on environmental attributes (noninstitutional character, sensory stimulation, lighting, safety), studies concerning building organization (orientation, outdoor space), and research on specific rooms and activity spaces (bathrooms, toilet rooms, dining rooms, kitchens, and resident rooms). The analysis reveals major themes in research and characterizes strengths and shortcomings in methodology, theoretical conceptualization, and applicability of findings.

Mood and general behavior of patients with severe dementia during one year of supervised, individualized planned care and systematic clinical supervision. Comparison with a similar control group

The aim of this study was to evaluate the effects of one year of systematic clinical supervision, and supervised individually planned care on the mood and general behavior of patients with dementia in relation to their cognitive function and level of confusion. The intervention was carried out in a ward devoted to the care of patients with severe dementia (EW), with a similar ward (CW) where no changes were made serving as a control. Each ward housed 11 patients, of whom 7 patients in each ward survived throughout the study time. Assessment of the patients' mood, general behavior, cognitive functions (MMSE), orientation and confusion (OBS) was made at baseline, and after 6 and 12 months of intervention. Significant deteriorations for the patients in CW were seen during the study period as regards the factor strength, functional performance and orientation in the ward, and speech performance and psychomotor slowing. For the patients in the EW, deterioration was seen only in the factor accessibility, and improvement was seen in the factor sensitivity and euphoria. The differences indicated that the development in the two wards went in opposite directions to the benefit of the patients in the EW. Because of the small sample size, the findings are more the result of a pilot trial, rather than generalizable. The intervention, however, seemed to have a positive effect on the secondary symptoms of the disease.

Development and psychometric evaluation of the Environment-Behavior Interaction Code (EBIC)

BACKGROUND

Although the behavioral changes with progressive dementia are seen to increasingly depend on the environmental context until late stage disease, measurement has not reflected this interaction in real time to allow examination of antecedents to disruptive behavior.

OBJECTIVES

To develop and evaluate the psychometric properties of the Environment-Behavior Interaction Code (EBIC) for use in dementia care research with either sequential or nonsequential analyses of behavioral data.

METHOD

Development of the computer-based (sequential event format) EBIC provided an observational coding system to classify all behavior and environmental context in real time, so that the probability of social environmental antecedents to resident disruptive behavior could be estimated. A checklist (interval format) EBIC, based on the same behavioral taxonomy, was developed for clinical outcome research. A total of 158 elderly residents of dementia care units were purposively selected from three large long-term care facilities for the psychometric study components.

RESULTS

Psychometric results indicated significant (p < 0.01) known-groups validity for the disruptive behavior construct, which was defined as a composite of aversive, harmful, and high intensity neutral behavior. Interrater agreement for the event format of the EBIC was estimated by average kappa (0.65) and percentage agreement (78%). For the interval format, the mean interrater kappa was 0.80 with 96% agreement. Stability of the event format using a 2-week retest interval ranged from r= .50 (positive behavior) to r = 0.73 (negative behavior, defined as aversive + harmful). On replication with a new sample, stability was higher for positive (r = 0.92) and negative (r = 0.95) components, and for composite scores of nondisruptive (positive + low intensity neutral; r = 0.65) and disruptive (r= 0.85) behavior.

CONCLUSION

This research provided support for the reliability and validity of both event and interval EBIC formats. Measurement using the EBIC taxonomy has applicability to dementia care research questions that call for either sequential analysis of social interactions or nonsequential analysis of behavioral outcomes in intervention studies.

A stimulation-retreat special care unit for elders with dementing illness

Two equivalent special care nursing home units for elders with dementing illness were randomly designated as experimental and control units for an intervention called the "stimulation-retreat" model. This model introduced a set of staffing and program changes whose purpose was to diagnose, prescribe, and apply a package of care according to individual needs for additional stimulation or relief from stimulation ("retreat"). A total of 49 experimental and 48 control unit residents completed 12 months of care and were evaluated at baseline, 6 months, and 12 months. It was hypothesized that the intervention would not affect the basic disability (cognitive and activities of daily living functions), would improve negative behaviors and observed affects, and would have maximum impact in increasing positive behaviors and affects. Over time, most functions worsened, including negative attributes and affects. Lesser decline in positive affect and increases in external engagement, however, led to the conclusion that the intervention showed a marginally significant and selective effect on positive behaviors and affect.

Effects of clinical supervision on nurse-patient cooperation quality: a controlled study in dementia care

An intervention consisting of individualized planned care for patients and regular clinical systematic supervision for nurses was carried out on a ward for dementia care (the experimental ward, EW). On a similar control ward (CW), no changes were made. Observations of nurse-patient cooperation during morning care were collected at both wards, before and during the intervention. The observations (N = 107) were analyzed blindly and sorted into already-developed categories. The distribution of the cooperation-style categories was then analyzed statistically. The patients who survived throughout the study period (N = 18) were also compared over time. Nurse-patient cooperation at the EW improved significantly during the intervention period, whereas, at the CW, it deteriorated (p = .02). Status of surviving patients followed the same pattern (p = .001). The findings indicate that such interventions can improve the quality of nurse-patient cooperation in dementia care.
