Modelling factors of urinary incontinence in institutional older adults with dementia

Incidence, Prevalence, and Risk for Urinary Incontinence for People with Dementia in the Community in Aotearoa New Zealand: An interRAI Study

OBJECTIVES

To identify 1-year period prevalence, 5-year incidence rate, and risks for urinary incontinence (UI) for people living with dementia.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Participants completed an International Residential Assessment Instrument Home Care (interRAI-HC) assessment in a 5-year period between August 1, 2016 and July 31, 2021 in Aotearoa New Zealand (N = 109,964).

METHODS

For prevalence analysis, a dementia cohort was selected for a 1-year period from August 1, 2020 to July 31, 2021 (n = 7775). For incidence analysis, participants in the dementia cohort were followed from the first dementia diagnosis during the 5-year period. Dementia was identified by combining diagnoses of "Alzheimer's disease" and "Dementia other than Alzheimer's disease." Participants were coded with UI if they were infrequently, occasionally, or frequently incontinent or if continence was managed with catheter/ostomy. Univariate and multivariate logistic regression analyses identified risk factors predicting UI onset. Cox regression analysis compared survival curves (months without UI) of the dementia and non-dementia cohorts, adjusting for variables significantly associated with incident UI in either cohort.

RESULTS

The 1-year period (August 1, 2020 to July 31, 2021) prevalence of UI was 50.1% among people with dementia. The 5-year incident UI rate was 30.2 per 100 person-years for the dementia cohort and 24.5 per 100 person-years for the non-dementia cohort. Parkinson's disease posed the greatest risk of UI in both cohorts [dementia cohort odds ratio (OR), 3.0; 95% CI, 2.1-4.2; non-dementia cohort OR, 1.7; 95% CI, 1.4-2.0]. Controlling for risk factors, the hazard ratio for UI was 1.4 for people with dementia.

CONCLUSIONS AND IMPLICATIONS

UI affects a significant proportion of people with dementia in Aotearoa New Zealand. Health professionals should directly ask about UI and consider living arrangements and comorbidities for people with dementia. Data-driven insights from interRAI-HC can guide resource allocation and service planning.

Urinary Incontinence in a Community-Based Autopsy Cohort Is Associated with Limbic Predominant Age-Related TDP-43 Encephalopathy Neuropathologic Changes

BACKGROUND

Dementia and urinary incontinence (UI) are etiologically complex clinical syndromes. Dementia and UI often occur in the same individuals, but underlying factors connecting them are incompletely understood.

OBJECTIVE

Query data from a community-based autopsy series to assess pathologies that underlie UI.

METHODS

Included research subjects came to autopsy from the University of Kentucky Alzheimer's Disease Research Center longitudinal cohort. A total of 368 research volunteers met inclusion criteria for this cross-sectional study. The average age at death was 85.3 years and the average number of annual clinic visits was 5.2 visits. Statistical models were run to evaluate which pathologies were associated with UI. Data included pathologies scored according to conventional stage-based systems, and these studies were complemented by quantitative digital neuropathology.

RESULTS

Dementia was diagnosed at the final clinical visit in 208 (56.7% of the sample) and UI was documented in 156 (42.7%). UI was associated with depression and dementia (both p < 0.001). More women than men had a history of UI (p < 0.04), and women with UI had had more biological children than those without UI (p < 0.005). Participants with limbic predominant age-related TDP-43 encephalopathy neuropathologic changes (LATE-NC) were more likely to have UI than those without LATE-NC (p < 0.001). The presence of LATE-NC (Stage > 1) was associated with UI with or without severe Alzheimer's disease neuropathologic changes and/or Lewy body pathology.

CONCLUSION

In this community-based autopsy cohort, multiple factors were associated with UI, but the neuropathologic change most robustly associated with UI was LATE-NC.

Characteristics, scope of activity, and negative emotions in elderly women with urinary incontinence: Based on a longitudinal follow-up in Shanghai, China

We conducted a study to assess the characteristics, scope of activity, and negative emotions in elderly women with urinary incontinence (UI) based on a longitudinal follow-up conducted in Shanghai, China from 2013 to 2019. A total of 3,531 elderly women were included in the final analysis, and 697 women who experienced UI during follow-up were included in the UI group. Subjects with UI were subdivided into those with partial UI (UI once a day or less) and UI (frequent UI). Two thousand eight hundred and thirty-four women who did not have UI during the same period served as the control group. The prevalence of UI was 19.74% in this study. Logistic regression analysis revealed that being older (> 80 years of age), having a high level of education (> 12 years; elderly people with a high level of education may pay more attention to their health and notice UI more readily), a low personal monthly income (≤ 3,000 RMB), more gravidity/parity, and having a chronic disease (chronic obstructive pulmonary disease (COPD), dementia, or Parkinson's disease) were risk factors for UI (p < 0.05). About 60% of women in the partial UI group engaged in daily activities outdoors, while this number decreased sharply to 3.6% in the UI group. Women in the UI group were more likely to have negative emotions, such as depression, anxiety, irritability, or feeling worthless (p < 0.001). Among elderly women with dementia, those with UI had defects in terms of judgment in everyday life, the ability of convey information, and the ability to understand information (p < 0.05). More attention needs to be paid to the adverse effects of UI on activities of daily living (ADL) and mental health in the future.

Reliability and Validity of a Chinese Version of the Cohen–Mansfield Agitation Inventory-Short Form in Assessing Agitated Behavior

Background: Patients with dementia often present agitated behaviors. The Cohen–Mansfield Agitation Inventory-short form (CMAI-SF) is one of the most widely used instruments to evaluate agitated behaviors that affect patients’ quality of life and impose burden on caregivers. However, there is no simplified Chinese version of the CMAI-SF (C-CMAI-SF) in clinical settings. Purpose: This study aimed to develop a Chinese version of the C-CMAI-SF and examine its validity and reliability. Methods: This cross-sectional study included three phases. In Phase I, the original CMAI-SF was translated to Chinese. In Phase II, experts were invited to examine the content validity index (CVI). Phase III was conducted to test the validity and reliability of the C-CMAI-SF. Results: The scale showed good validity and reliability with a scale-level CVI of 0.89, Cronbach’s alpha (measure of internal consistency) of 0.874, and test–retest correlation coefficient of 0.902 (for 257 individuals). Using factor analysis, three factors were identified. Regarding concurrent validity, the C-CMAI-SF score was correlated with the Neuropsychiatric Inventory (agitation aggression subscale) and the Cornell Scale for Depression in Dementia (agitation subscale). Conclusions: The study demonstrated that the C-CMAI-SF is a valid and reliable instrument for evaluating agitated behaviors in people with dementia. Relevance to clinical practice: The C-CMAI-SF is an easy and quick tool used to identify and evaluate agitated behaviors in busy clinical settings.

Perceptions and help-seeking behaviours among community-dwelling older people with urinary incontinence: A systematic integrative review

AIM

To synthesize research evidence on perceptions and help-seeking behaviours in community-dwelling older people with urinary incontinence based on the Capability-Opportunity-Motivation-Behaviours model.

BACKGROUND

Urinary incontinence is highly prevalent in community-dwelling older people, yet only a small proportion seek help from health professionals. Untreated urinary incontinence has a detrimental impact on older people's quality of life and distresses their caregivers.

DESIGN

Systematic integrative review.

DATA SOURCES

Ten databases were searched systematically between 9 November 2020 and 17 December 2020 including Medline (PubMed), CINAHL, Ageline, Web of Science, Scopus, ProQuest, Psyclnfo, CNKI, Wanfang and Vip.

REVIEW METHODS

Quality appraisal was applied to assess the quality of selected articles. Data relevant to the review aim were extracted from included articles for analysis. Convergent qualitative synthesis was used to synthesize findings.

RESULTS

Twenty articles were included and two main themes with six sub-themes were identified. Theme one described three common perceptions including urinary incontinence as a part of normal ageing, a stigma and a health problem. Each perception had a profound impact on older people's motivation to self-report the problem to health professionals. Theme two revealed three main help-seeking approaches comprising self-help, help from friends and help from health professionals. Of these, self-help was the dominant approach used to conceal urinary incontinence and contributed to social isolation.

CONCLUSION

Improving urinary incontinence management in community-dwelling older people requires the development of their capability and motivation, and increased opportunities to access and gain help from skilled health professionals.

IMPACT

Findings can facilitate resource development to improve health literacy for the general public pertinent to urinary incontinence and associated stigma. Moreover, findings can inform a user-friendly reporting and referral system for the problem. In addition, findings can inform education and skill training for health professionals, older people and their caregivers to effectively manage the problem.

Determinants of Urinary Incontinence and Subtypes Among the Elderly in Nursing Homes

Urinary incontinence (UI) is a common problem among older adults. This study investigated the prevalence of UI in nursing home residents aged ≥75 years in China and examined potential risk factors associated with UI and its subtypes. Data were collected during face-to-face interviews using a general questionnaire, the International Consultation Incontinence Questionnaire Short-Form, and the Barthel Index. A total of 551 participants aged ≥75 years residing in Changsha city were enrolled from June to December 2018. The UI prevalence rate among nursing home residents aged ≥75 years was 24.3%. The most frequent subtype was mixed (M) UI (38.1%), followed by urge (U) UI (35.1%), stress (S) UI (11.9%), and other types (14.9%). In terms of severity, 57.5% had moderate UI, while 35.1% had mild and 7.5% had severe UI. Constipation, immobility, wheelchair use, cardiovascular disease (CVD), and pelvic or spinal surgery were significant risk factors for UI. Participants with a history of surgery had higher risks of SUI (odds ratio [OR] = 4.87, 95% confidence interval [CI]: 1.55–15.30) and UUI (OR = 1.97, 95% CI: 1.05–3.71), those who were immobile or used a wheelchair had higher rates of MUI (OR = 11.07, 95% CI: 4.19–29.28; OR = 3.36, 95% CI: 1.16–9.78) and other UI types (OR = 7.89, 95% CI: 1.99–31.30; OR = 14.90, 95% CI: 4.88–45.50), those with CVD had a higher rate of UUI (OR = 2.25, 95% CI: 1.17–4.34), and those with diabetes had a higher risk of UUI (OR = 2.250, 95% CI: 1.14–4.44). Use of oral antithrombotic agents increased UUI risk (OR = 4.98, 95% CI: 2.10–11.85) whereas sedative hypnotic drug use was associated with a higher risk of MUI (OR = 3.62, 95% CI: 1.25–10.45). Each UI subtype has distinct risk factors, and elderly residents of nursing homes with a history of CVD and pelvic or spinal surgery who experience constipation should be closely monitored. Reducing time spent in bed and engaging in active rehabilitation including walking and muscle strengthening may aid in UI prevention and treatment.

An Exergame Solution for Personalized Multicomponent Training in Older Adults

In addition to contributing to increased training motivation, exergames are a promising approach to counteract age-related impairments. Mobility limitations, cognitive impairment, and urinary incontinence are very common in older adults. To optimally address these conditions, exergames should include interventions for strength, balance, cognition, and pelvic floor muscle training. In this study, we develop a personalized multicomponent exergame solution for the geriatric rehabilitation of age-related impairments. The exergame can provide interventions for balance, strength, cognition, and urinary incontinence in one single session, accommodating the needs of older adults with multiple disabilities. For its development, we involved a multidisciplinary team that helped us to specify the structure and contents of the exergame considering training requirements, game design principles, and end-user characteristics. In addition to allowing the customization of the training components, the exergame includes automatic adaptation of difficulty/load, in line with player progress over time. The game mechanics ensures the fulfilment of training needs as defined by the therapist. The exergame is cross-platform compatible (web-based) and includes novel means of interaction with wearable sensors.

Understanding how to facilitate continence for people with dementia in acute hospital settings: a mixed methods systematic review and thematic synthesis

BACKGROUND

People living with dementia (PLWD) are at significant risk of developing urinary and/or faecal incontinence and are also at risk of functional incontinence or being labelled as being incontinent. Despite the growing population of PLWD and importance of continence care, little is known about the appropriate management, organisation, and interactional strategies for PLWD admitted to acute hospitals. This mixed methods systematic review and thematic synthesis sought to identify successful strategies across all care settings that could then be used to inform innovations in continence care for PLWD in the acute hospital setting.

METHODS

In phase 1, a scoping search of two electronic databases (MEDLINE and PsycINFO) and a consultation with stakeholders was undertaken. Findings were presented to the project steering group and two priority areas for phase 2 were identified which were communication and individualised care plans. In phase 2, eight databases and relevant UK government and other organisational websites were searched for English language citations from inception to August 2020. Critical appraisal was conducted using the Mixed Methods Appraisal Tool (MMAT Version 11). Thematic synthesis was employed and the strength of synthesised findings for the intervention studies was assessed using the GRADE approach and the confidence in synthesised qualitative and survey findings was assessed using the CERQual approach.

RESULTS

In phase 1, 1348 citations were found and 75 included. In phase 2, 6247 citations were found, 14 research studies and 14 policy and guidance documents were included. The quality of studies varied. Material was synthesised into three overarching syntheses which were: communication this is dignified, person-centred and respectful; communication during outpatients apointments and delivering individualised continence care.

CONCLUSIONS

Recognising that PLWD are not always able to communicate their continence needs verbally is important. Incorporating interpersonal and communication skills into the context of continence care within training for those working with this patient group is crucial for continence to be maintained during an acute admission. Continence care in the acute setting should be tailored to the individual and be developed in partnership with staff and caregivers.

The development and validation of instruments to measure dignity-protective continence care for care-dependent older people in residential aged care facilities: A study protocol

AIMS

To develop and validate two instruments to measure dignity-protective continence care for care-dependent older people in residential aged care facilities: one instrument to be completed by care recipients and another for healthcare professionals.

METHODS

The first phase of the project will involve a review of literature to identify the attributes of "dignity-protective continence care" for older people, which will be used to design the initial drafts of the instruments. Thereafter the Delphi survey technique will be used to establish the face and content validity of the draft instruments with three purposive samples; (a) care recipients (care-dependent older people with decisional capacity), (b) formal carers (nurses and personal care workers from residential aged care facilities, and (c) healthcare professionals with gerontological expertize in the management of incontinence. After instrument development, a large cross-sectional survey of care recipients and formal carers will be conducted to establish the internal consistency and construct validity of the instruments. This will be followed by a series of tests to establish their test-retest reliability.

CONCLUSION

The completed research will result in two reliable and valid instruments that will support broader efforts to ensure that care practices in residential aged care facilities do not violate the dignity of care-dependent older people with continence care needs, and allow care partners and providers to act upon the results.
