Comparison of the effectiveness of two protocols for treating nursing home residents with advanced dementia.

The Serial Trial Intervention (STI) is a decision support tool to address the problem of underassessment and undertreatment of pain and other unmet needs of people with dementia. This study compared the effectiveness of the 5-step and 9-step versions of the STI using a two-group repeated measures quasi-experimental design with randomization of 12 matched nursing homes. The sample consisted of 125 residents with moderate to severe dementia. Both the 5- and 9-step STIs significantly decreased discomfort and agitation from pre- to posttest (effect sizes = 0.45 to 0.90). The 9-step version was more effective for comorbid burden and increased cortisol slope (effect sizes = 0.50 and 0.49). Process variables were all statistically significantly improved using the 9-step STI. Nurse time was not different between the two groups. The clinical decision support rules embedded in the STI, particularly the 9-step version, helped nurses change practice and improved resident outcomes.

Failure to identify behavioral symptoms of people with dementia and the need for follow-up physical assessment.

This descriptively designed study examined the sensitivity and specificity of staff nurses' identification of behavior change in nursing home residents with dementia. Behavior changes and whether further physical assessment was indicated were described and compared with judgments made by one expert advanced practice nurse. The convenience sample included 155 residents and 38 staff nurses from 11 nursing homes. Verbal symptoms and body part cues were the most prevalent behaviors, regardless of the assessor. Sensitivity, or probability of identifying a real behavior change, was generally low for the staff nurses, ranging from 35% to 65% for the different types of behaviors, while specificity was high at more than 95%. Additional assessment was believed to be needed for 51% of residents by the staff nurse and for 73% of residents by the expert. This study found that staff nurses are under-identifying behavior changes and the need for additional physical assessment.

Using principles of diffusion of innovation to improve nursing home care.

Principles of diffusion of innovation were used to change care provided to people with dementia in 9 nursing homes. Use of these principles was associated with increased assessment in response to behavior change, increased administration of analgesics, and a significant decrease in resident behavioral symptoms. Results of this study support the emerging consensus that diffusion of innovation is an effective model for making changes in performance of healthcare organizations.

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.

The assessment of discomfort in dementia protocol.

Many people with dementia are unable to clearly or consistently verbalize pain symptoms. The Assessment of Discomfort in Dementia (ADD) Protocol is a systematic tool that can be used by nurses to make a differential assessment and treatment plan for both physical pain and affective discomfort experienced by people with dementia. This ADD Protocol is based on the assumption that behaviors associated with dementia are symptoms of unmet physiologic and/or nonphysiologic needs. Steps of the process include a physical assessment, a review of the patient's history, an assessment of affective needs including environmental stress and sensoristasis, and the administration of analgesics. The ADD Protocol is unique in that it uses "as needed" analgesics as a part of the assessment process. The dualistic perspective, in which physical and affective needs are considered in tandem, is an essential and innovative feature of the ADD Protocol.
