Sustainable nurse-led care for people with dementia including mild cognitive impairment and their family in an ambulatory care setting: A scoping review

The prevalence of mild cognitive impairment and dementia among rural dwellers: A systematic review and meta-analysis

The mild cognitive impairment (MCI) and dementia in rural areas are increasingly attracting public attention. However, their prevalence is still unclear. This study aims to reveal the distribution of MCI and dementia in rural areas. We systematically searched PubMed, Web of Science, Embase, and PsycINFO up to June 2023 for cohort and cross-sectional studies. Meta-analysis was conducted using random-effects models to evaluate the prevalence of MCI and dementia. Thirty-five studies with 16,936 participants met the inclusion criteria. The pooled prevalence of MCI and dementia was 27 % (n = 12, 95 %CI = 0.21-0.32, I2 = 99.5 %, P < 0.001) and 7 % (n = 27, 95 %CI = 0.05-0.08, I2 = 99.30 %, P < 0.001), respectively. Subgroup analyses revealed that aged 60 years or older [(MCI: 29 %, 95 %CI = 0.20-0.38, I2 = 99.7 %, P < 0.001), (dementia: 9 % (95 %CI = 0.06-0.12, I2 = 99 %, P < 0.001)], female [(MCI: 29 %, 95 %CI = 0.19-0.40, I2 = 99.3 %, P < 0.001), (dementia: 7 %, 95 % CI = 0.04-0.12, I2 = 98.66 %, P < 0.001)], a-MCI (19 %, 95 %CI = 0.12-0.26, I2 = 97.62 %, P < 0.001) and AD (4 %, 95 %CI = 0.02-0.05, I2 = 98.60 %, P < 0.001) showed higher prevalence. The prevalence of MCI and dementia in rural China was 23 % (95 %CI = 0.18-0.29, I2 = 99.5 %, P < 0.001) and 6 % (95 %CI = 0.04-0.08, I2 = 99.6 %, P < 0.001), respectively. Implementing cognitive impairment screening and intervention measures is necessary to improve the cognitive function of the rural population.

A description of risk associated with use of antipsychotics among community dwelling older adults: A descriptive cross-sectional study

The objective of this research was to analyze the risk of adverse effects in patients older than 65 years with dementia and in concomitant treatment with antidementia and antipsychotic drugs and who are cared for by community nurses. A retrospective cross-sectional descriptive study was carried out. A total of 332 patients who were cared for by primary care teams participated. Most of the patients were women, totally dependent for the basic activities of daily living and residing in the family home. They were polymedicated and there was poor therapeutic adherence. The risk of adverse effects was higher in polymedicated patients who had been taking antipsychotics for longer periods and in those who had a main caregiver. However, those patients who had been assessed by the community nurse were protected from suffering adverse effects. This study demonstrates how integrated and continuous nursing care can reduce adverse effects in this type of patient.

The Effectiveness of a Community Nurse-Led Support Program for Dementia Caregivers in Chinese Communities: The Chongqing Ageing and Dementia Study

Background

As the primary caregivers for people with dementia in China, family caregivers face a significant care burden that can negatively impact their mental and physical health. It is vital to investigate ways to support these caregivers.

Objective

To assess the effectiveness of a program led by community nurses to support caregivers of individuals with dementia.

Methods

A total of 30 caregivers received nurse-led support in addition to usual care, while 28 caregivers received only usual care. The primary outcome was caregivers' sense of competency in providing dementia care, which was measured using the Short Sense of Competence Questionnaire (SSCQ). Secondary outcomes included caregivers' ability to perform daily activities, behavioral and psychological symptoms of dementia (BPSD) using a neuropsychiatric inventory questionnaire, and quality of life using the short form health survey (SF-36). The trial was registered at the Chinese Clinical Trial Registry (ChiCTR 2300071484).

Results

Compared to the control group, the intervention group had significantly higher SSCQ scores and a lower caregiver distress index over time. Physical and mental health-related quality of life also improved significantly among caregivers in the intervention group. However, there was no significant difference between the two groups in terms of activities of daily living and BPSD.

Conclusions

The community nurse-led support program significantly improved caregivers' competency in providing dementia care and quality of life and reduced distress. These findings have important implications for dementia care policies, resources, and workforce development in China, including strengthening community dementia care services through collaboration with specialists in hospitals.

Systematic Review and Meta-Analysis of Effects of Nurse-Led Intervention for People With Dementia

BACKGROUND

Nurses' primary role in clinical settings for persons living with dementia is to lessen the strain of dementia on daily life, monitor comorbidities, and manage medications. However, no comprehensive literature review has investigated the effectiveness of nurse-led interventions for persons living with dementia.

OBJECTIVE

The purpose of this study was to evaluate randomized controlled trials on the efficacy of nurse-led dementia interventions and provide an extended range of outcomes related to cognitive function, depression, and quality of life.

METHODS

A comprehensive literature search of six databases was conducted from database inception to August 10, 2022. Methodologies were evaluated, followed by a pooled analysis using random effects models to explain the effects of nurse-led dementia interventions on patients.

RESULTS

Nurse-led interventions were more effective than standard care in alleviating depression and improving quality of life. However, they did not enhance cognitive performance.

DISCUSSION

Nurse-led interventions for dementia alleviate depression and improve quality of life. However, because of lack of randomized controlled trials, the analysis found less effectiveness in improving cognitive function. Therefore, further trials are needed to corroborate these findings.

'Redeemed' or 'isolated': A systematic review of the experiences of older adults receiving a mild cognitive impairment diagnosis

BACKGROUND

Understanding the experiences of older adults living with MCI can benefit healthcare professionals in diagnosing and implementing early interventions to delay cognitive decline.

OBJECTIVE

To assess and synthesize qualitative research exploring the experience of older adults diagnosed with MCI.

METHODS

PubMed, Embase, CINAHL, Web of Science, and PsycINFO databases were searched. Studies involving the experience of being diagnosed with MCI in older adults were included. Thomas and Harden's methodology of synthesizing qualitative studies was used.

RESULTS

Eleven studies were included. Three themes were identified: perceived reality of the MCI diagnosis; emotional and psychological responses to the MCI label; coping engaged in parallel processing. Older adults had confusing perspectives on the MCI diagnosis, leading to complicated and diverse emotional reactions and coping measures.

CONCLUSIONS

The relationship between perspectives, emotional reactions, and coping methods might be the key for healthcare professionals to break through the early diagnosis and intervention of MCI.
