Effects of the Serial Trial Intervention on discomfort and behavior of nursing home residents with dementia.

This study tested the effectiveness of the Serial Trial Intervention (STI), an innovative clinical protocol for assessment and management of unmet needs in people with late-stage dementia. A double-blinded randomized experiment was conducted in 14 nursing homes with 114 subjects. The treatment group had significantly less discomfort than the control group at posttesting and more frequently had behavioral symptoms return to baseline. The group of nurses using the STI also showed more persistence in assessing and intervening than control group nurses did. There was a statistically significant difference between the groups in the use of pharmacological, but not nonpharmacological, comfort treatments. Results suggest that the STI is effective and that effective treatment of discomfort is possible for people with late-stage dementia.

The Serial Trial Intervention: an innovative approach to meeting needs of individuals with dementia.

Individuals with dementia often use behaviors rather than specific verbal complaints to express the presence of a symptom or need. The Serial Trial Intervention uses systematic serial assessments and sequential trials of treatments to identify and treat unmet needs that may be the underlying cause of these behaviors. Because chronic pain is common and often under-treated in this population, a trial of analgesics is used when other approaches, including nonpharmacological treatments, have not been effective. A systematic approach to nursing assessment and treatment is needed to identify and treat discomfort and other unmet needs of individuals with dementia.

A model of consequences of need-driven, dementia-compromised behavior.

PURPOSE: To extend the original need-driven, dementia-compromised behavior (NDB) model by explaining the consequences of behavioral symptoms for the person with dementia. ORGANIZING CONSTRUCT AND METHODS: Literature is reviewed and the consequences of expressing needs through need-driven, dementia-compromised behaviors are posited. The consequences of need-driven, dementia-compromised behavior (C-NDB) theory is proposed as a framework to improve understanding of the person with dementia and the consequences of behavioral symptoms and unmet needs. FINDINGS: Instead of normative verbal communication, people with significant dementia commonly communicate need via non-normative behaviors, making it difficult for caregivers to know that the person has a need and the extent of such need. Not meeting needs of people with dementia affects the person with dementia, care factors, and contextual factors. Cascading effects occur in which not meeting the original need results in new needs and behavioral symptoms. CONCLUSIONS: This framework indicates the consequences of expressing need behaviorally rather than verbally and shows that caregiver actions might moderate the events that lead to many needs being unresolved. Suggestions are made regarding future research questions deduced from the model.

Effect of the BACE intervention on agitation of people with dementia.

PURPOSE: This study tests the effectiveness of the theoretically driven BACE (i.e., Balancing Arousal Controls Excesses) intervention in decreasing agitation in residents of long-term care with moderate or severe dementia. DESIGN AND METHODS: A pretest-posttest double-blinded experimental design with random assignment was used with a sample of 78 participants. The BACE intervention controls the daily activity schedule so that there is a balance between a person's high-arousal and low-arousal states. The outcome measure was observed agitation. RESULTS: When time spent in arousal imbalance at pretest was controlled for, a repeated measures analysis of covariance revealed a statistically significant Group x Time interaction, F(1, 69) = 4.26, p =.043, with a partial eta(2) =.06. The average change in agitation for the treatment group was a decrease of 8.43 points (SD = 12.01) from pretest to posttest, an effect size of.7. IMPLICATIONS: The results of this study support the theory that balancing arousal states by using an individualized approach is effective in decreasing agitation levels of people with dementia.
