Exploratory factor analysis and Rasch analysis to assess the structural validity of the Adult Social Care Outcomes Toolkit Proxy version (ASCOT-Proxy) completed by care home staff.

PURPOSE: Rasch analysis and exploratory factor analysis (EFA) were used to evaluate the structural validity of the ASCOT-Proxy measures completed by staff on behalf of older adults resident in care homes, by comparison to the ASCOT-SCT4, the measure of social care-related quality of life (SCRQoL) from which the ASCOT-Proxy was developed. METHODS: EFA was conducted on the ASCOT-SCT4 and the two ASCOT-Proxy measures (Proxy-Proxy, Proxy-Resident), to determine if they retained the single factor of the original ASCOT-SCT4 measure found in samples of older community-dwelling adults. Rasch analysis was also applied to measures with a single factor structure in the EFA. RESULTS: ASCOT-Proxy-Resident had a single factor structure, as did the original ASCOT-SCT4 (also, found in this analysis when completed by care home staff). The ASCOT-Proxy-Proxy had a two factor structure. Rasch analysis of ASCOT-Proxy-Resident and ASCOT-SCT4 had an acceptable model fit, internal consistency and met the assumptions of unidimensionality and local independence. There was evidence of less than optimal distinguishability at some thresholds between responses, and low frequency of rating of the 'high level needs'. CONCLUSION: The ASCOT-Proxy-Resident is a valid instrument of SCRQoL for older adults resident in care homes, completed by staff proxies. Due to the two-factor structure, which differs from the original ASCOT-SCT4, we do not recommend the use of the ASCOT-Proxy-Proxy measure, although collecting data as part of the ASCOT-Proxy questionnaire may support its feasibility and acceptability. Further qualitative study of how care home staff complete and perceive the ASCOT-Proxy is encouraged for future studies.

Developing a list of core competencies for medical aspects of healthcare delivery in care homes: scoping review and Delphi process.

BACKGROUND: Care home residents live with frailty and multiple long-term conditions. Their medical management is complex and specialised. We set out to develop a list of core competencies for doctors providing medical care in long-term care homes. METHODS: A scoping review searched MEDLINE, EMBASE and CAB Abstracts, supplemented by grey literature from the Portal of Online Geriatrics Education and the International Association of Geriatrics and Gerontology, looking for core competencies for doctors working in care homes. These were mapped to the UK nationally mandated Generic Professional Competencies Framework. A Delphi exercise was conducted over three rounds using a panel of experts in care homes and medicine of older people. Competencies achieving 80% agreement for inclusion/exclusion were rejected/accepted, respectively. RESULTS: The scoping review identified 22 articles for inclusion, yielding 124 competencies over 21 domains. The Delphi panel comprised 23 experts, including 6 geriatricians, 4 nurses, 3 general practitioners, 2 advanced clinical practitioners, 2 care home managers, and one each of a patient and public representative, palliative care specialist, psychiatrist, academic, physiotherapist and care home audit lead. At the end of three rounds, 109 competencies over 19 domains were agreed. Agreement was strongest for generic competencies around frailty and weaker for sub-specialist knowledge about specific conditions and competencies related to care home medical leadership and management. CONCLUSION: The resulting competencies provide the basis of a curriculum for doctors working in long-term care homes for older people. They are specialty agnostic and could be used to train general practitioners or medical specialty doctors.

The prevalence, awareness, treatment, and control of hypertension in older adults with an intellectual disability in Ireland: a cross sectional study.

AIMS: Hypertension is a leading risk factor for cardiovascular disease, accounting for almost 50% of ischaemic heart disease mortality. This study aims to identify the prevalence, awareness, treatment, and control of hypertension and their predictors in older adults with an intellectual disability (ID). METHODS AND RESULTS: This cross-sectional study utilized data from the ID Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA). Participants were drawn from the nationally representative sample and included those who completed the self/informant report measures, in addition to objective blood pressure (BP) measurement. From the 551 individuals with ID, aged ≥40 years, hypertension prevalence was 35.2% [95% confidence interval (CI) 31.2-39.2%]. Of those with hypertension, 44.3% (95% CI 37.1-51.5%) were aware of their hypertensive status, and 64.2% (95% CI 57.3-71.1) were taking antihypertensive medication. Among those on treatment, 70.8% (95% CI 61.8-78.2%) had their BP controlled to below 140/90 mmHg. Significant predictors of awareness were age (P = 0.036) and level of ID (P = 0.004), predictors of treatment were age (P = 0.002), level of ID (P = 0.019), and diabetes (P = 0.001). Both diabetes and female gender were predictors of control of hypertension (P = 0.013 and P = 0.037, respectively). CONCLUSION: The prevalence of hypertension in older adults with ID was lower than reports for the general Irish population, with overall levels of treatment and control, when identified, higher in the ID population. There was under-treatment and lower levels of awareness among those with more severe ID, which requires addressing. The finding, that when diagnosed, people with ID respond well to treatment should encourage addressing the under-treatment found here.

The nature and quality of friendship for older adults with an intellectual disability in Ireland.

BACKGROUND: Friendship is important to quality of life, yet people with intellectual disability have more restricted social networks and fewer friends outside family and support staff. METHOD: Data from a nationally representative longitudinal study of older adults with intellectual disability (aged >40) examined rates and types of friends. Factors associated with having a best friend and friendship quality were explored. RESULTS: A large majority (92.4%) had friends but just over half (52%) had a best friend. Co-resident friends (71.8%) were more common than non-resident friends (62%), while staff friendships (62.5%) were important. The majority of best friends were peers with intellectual disability (63.2%), carer/service providers (15.9%) or family (8.4%). Challenging behaviour and communication difficulty were associated with reduced likelihood of having a best friend. A best friend with intellectual disability was associated with lower friendship quality scores. CONCLUSION: Limited choice and social opportunity may result in a precarious form of friendship for older people with intellectual disability that undermines their quality of life.

Communication difficulties in adults with Intellectual Disability: Results from a national cross-sectional study.

BACKGROUND: People with an intellectual disability (ID) are vulnerable to communication impairments, with consequences for employment, education, and social participation. AIMS: To identify the communication skills of a population of adults (40+ years) with ID and explore relationships between individual and environmental factors and communication skills. METHODS AND PROCEDURES: Data from a sample of 601 adults with ID was selected from the Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing (IDS-TILDA) addressing communication characteristics, demographics, co-morbidities, challenging behaviours, and social participation. A multiple regression model and a decision-making tree were built to identify factors related to communication abilities. OUTCOMES AND RESULTS: Overall, 57.9 % of participants experienced communication difficulties, with 23.5 % reporting severe difficulties. Only 75.1 % of participants communicated verbally; more than half found communicating with professionals and non-familiar partners difficult. Level of ID, low social participation, challenging behaviours, and diagnosis of Down syndrome were significantly associated with communication difficulties. CONCLUSIONS AND IMPLICATIONS: Communication difficulties are prevalent in adults with ID and are influenced by complex factors. Interventions to enhance interaction and quality of life of individuals with ID should consider communication opportunities, needs, and barriers.

Impact of stimulus frequency and recording electrode on electrocochleography in Hybrid cochlear implant users.

This report explores the impact of recording electrode position and stimulus frequency on intracochlear electrocochleography (ECoG) responses recorded from six Nucleus L24 Hybrid CI users. Acoustic tone bursts (250 Hz, 500 Hz, 750 Hz, and 1000 Hz) were presented to the implanted ear via an insert earphone. Recordings were obtained from intracochlear electrodes 6 (most basal), 8, 10, 12, 14, 16, 18, 20, and 22 (most apical). Responses to condensation and rarefaction stimuli were subtracted from one another to emphasize hair cell responses (CM/DIF) and added to one another to emphasize neural responses (ANN/SUM). For a fixed stimulus frequency, the CM/DIF and ANN/SUM magnitudes increased as the recording electrode moved apically. For a fixed recording electrode, as the stimulus frequency was lowered, response magnitudes increased. The CM/DIF and ANN/SUM response phase were generally stable across recording electrodes, although substantial phase shifts were noted for a few conditions. Given the recent interest in ECoG for assessing peripheral auditory function in CI users, the impact of stimulus frequency and recording electrode position on response magnitude should be considered. Results suggest optimal ECoG responses are obtained using the most apical recording electrode and a low frequency acoustic stimulus (250 Hz or 500 Hz).

Quantitative examination of the bone health status of older adults with intellectual and developmental disability in Ireland: a cross-sectional nationwide study.

OBJECTIVES: (1) To investigate the prevalence of osteopenia and osteoporosis among adults with intellectual disabilities (IDs) and (2) to examine alternative optimal bone screening techniques. DESIGN: Observational cross-sectional study. SETTING: Wave 2 (2013-2106) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing. PARTICIPANTS: A national representative sample of 604 male and female persons with ID aged 43 years and over. In total, 575 participants completed quantitative ultrasound (QUS) measurements for one or both feet. OUTCOME MEASURES: Participants underwent health assessments consisting of eight objective health measures including the standardised QUS of the calcaneus bone using a GE Lunar Achilles. A preinterview questionnaire and face-to-face interview were also completed. RESULTS: Objectively QUS identified poorer rates of bone health in people with ID overall with 74% indicating evidence of osteopenia (33.2%) or osteoporosis (41%). Females scored lower than males in the QUS t-scores -2.208 (±1.77) versus -1.78(±1.734). Bone status was stratified by gender (p=0.114), age (p=0.003), level of ID (p<0.0001) and living circumstance (p<0.0001). CONCLUSIONS: This study has shown the prevalence of poor bone health in people with ID is substantial implying an increased risk of fracture due to reduced skeletal integrity. QUS screening has been shown to be useful when combined with clinical risk factors.

Prevalence and associated factors of problem behaviours among older adults with intellectual disabilities in Ireland.

A growing number of adults with intellectual disabilities (ID) are reaching old age, however, little is known about epidemiology of problem behaviours (PBs) in this population. The aim was to identify the prevalence and associated factors of PBs among older adults with ID in Ireland. Data was generated from Wave 2 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA), a nationally representative sample of adults with ID aged ≥40. Data on PBs was available for 683 (98.3%) of individuals. Over half (53%; n = 362) reported displaying any PB (verbal aggression, physical aggression, destruction, self-injury, or "other" PB). Multivariate analyses indicated PBs were independently associated with moderate or severe/profound ID, living in a community group home or residential centre, experiencing a greater number of life events in the last year, taking psychotropic medication, and reporting a doctor's diagnosis of a psychiatric problem. A considerable number of older adults with ID in Ireland display PBs, which may hinder their opportunities to engage in community based activities and form meaningful social connections. High rates of psychotropic medication and doctor's diagnosis of psychiatric conditions and their associations with PBs were highlighted. Future research should examine mechanisms underlying these linkages.

Why do edentulous adults with intellectual disabilities not wear dentures? Wave 2 of the IDS TILDA cohort study.

PURPOSE: Older adults with intellectual disabilities (ID) are often edentulous. When total tooth loss occurs, they are very unlikely to wear complete removable dentures (CRDs) to restore oral function in Ireland. The reasons for this are unclear, though opinion holds that this is because dentists do not offer prosthodontic treatment to this group. In this study we ask edentulous older adults with ID why they do not wear dentures. METHODS: Cross-sectional survey data from Wave 2 of the Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing (IDS-TILDA) was examined to study reported denture wear among edentulous older adults with ID. RESULTS: Out of 692 participants, 186 were edentulous (26.9%), of whom 57 (30.6%) wore CRDs and 129 (69.3%) did not. Twelve of this 129 had dentures but did not wear them. Of the 117 respondents who reported that they did not have dentures, 99 (valid %=92.5%) did not want dentures, while only 8 did. No respondents in this study reported that they were denied denture therapy. Rather, they simply did not want dentures. Clinicians should understand that extra steps may be needed to ensure that consent is truly informed when patients opt for, or decline, complete denture therapy. CONCLUSION: While there is a high normative need for prosthodontic rehabilitation, expressed need is low. Extra steps may be necessary to ensure optimal outcomes for people with ID.

Mortality Rates in the General Irish Population Compared to those with an Intellectual Disability from 2003 to 2012.

BACKGROUND: Historically, there has been higher and earlier mortality among people with intellectual disability as compared to the general population, but there have also been methodological problems and differences in the available studies. METHOD: Data were drawn from the 2012 National Intellectual Disability Database and the Census in Ireland. A standardized mortality ratio (SMR) was calculated, as well as average age at death. Ratios and differences were further examined for the influence of age, gender and level of intellectual disability. RESULTS: Mortality in persons with intellectual disability was four times higher and they were, on average, dying 19 years earlier than peers in the general population. Women with intellectual disability were living longer than males with intellectual disability, but differences in survival as compared to the general population were greater for these women. There was little change in average age at death over 10 years, and death was earlier the more severe the level of intellectual disability. DISCUSSION: The use of mortality ratios rather than average age at death alone is recommended, as well as greater standardization in use of data sets including the whole population, given high levels of earlier deaths in people with intellectual disability.

What it's like to grow older: the aging perceptions of people with an intellectual disability in Ireland.

The Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing is a national longitudinal study on the aging of people with an intellectual disability (ID) using a randomly selected sample of people with ID over the age of 40. In total, 367 people with an ID completed the aging perception self-report only section. Over 57% of people described their health as very good to excellent with no significant difference in health perceptions found for gender, level of ID, or living circumstance. Exploring people's perceptions utilizing PASW Text Analytics for Surveys 4.1 perceptions often supported negative views of the consequences of aging. These findings suggest challenging negative aging concepts is essential to promote positivity with associated improved health and wellbeing.

Patterns of multimorbidity in an older population of persons with an intellectual disability: results from the intellectual disability supplement to the Irish longitudinal study on aging (IDS-TILDA).

UNLABELLED: Multimorbidity (2 or more chronic conditions) is being widely studied in older populations and this study explores both the relevance of emerging conceptualizations and the extent to which multimorbidity is a feature of aging in persons with an intellectual disability. METHODS: Data was generated from wave one of the intellectual disability supplement to the Irish longitudinal study on aging (IDS-TILDA) which included 753 persons with an ID aged 40 years and over. Information on the presence of 12 chronic conditions was collected using a standardized protocol administered in face to face interviews with persons with ID and/or their caregivers. Prevalence of multimorbidity was established and patterns were examined using logistic regression models. The patterns of multimorbidity for people with ID that emerged were then compared with those reported for other older adults. RESULTS: Multimorbidity was established for 71% of the IDS-TILDA sample with women at highest risk and rates of multimorbidity was high (63%) even among those aged 40-49 years. Eye disease and mental health problems were most often associated with a second condition and the most prevalent multimorbidity pattern was mental health/neurological disease. DISCUSSION: Further investigation, attention to mental health issues and the development of treatment guidelines that recognize chronic condition disease load are critical to mitigating the negative impact of multiple chronic conditions and preventing additional disability in adults with ID as they age.
