Prevalence of swallowing difficulties and associated factors in older people with intellectual disabilities.

BACKGROUND: We investigated the prevalence of swallowing difficulties and associated factors in people with intellectual disability. METHODS: We included people aged 50+ receiving care for people with intellectual disabilities. The Dysphagia Disorder Survey (DDS) was used to assess swallowing difficulties. We determined the agreement between the DDS and swallowing difficulties in medical records. We used logistic regression analyses to explore associated factors. RESULTS: One thousand and fifty people were included. The prevalence of swallowing difficulties was 43.8%. Swallowing difficulties were not reported in the medical records of 83.3% of these cases. Frailty (odds ratio (OR) = 4.22, 95% CI = 2.05-8.71), mobility impairment (OR = 2.50, 95% CI = 1.01-6.19), and mealtime dependency (OR = 3.05, 95% CI = 1.10-8.47) were independently associated with swallowing difficulties. CONCLUSION: Swallowing difficulties are prevalent in older people with intellectual disability but may be under-recognised. Frailty may be a good indicator for population-based screening for swallowing difficulties.

Degree of autonomy in making independent choices by frail older people with intellectual disabilities in a care home: A descriptive ethnographic study.

BACKGROUND: We aimed to gain more insight into autonomy of older people with intellectual disabilities in a residential care facility in making choices. METHODS: We performed a descriptive ethnographic study in a residential facility in the Netherlands for 22 persons, aged 54-89 years, with mild to moderate intellectual disabilities (IQ <70) and low social-emotional development levels. We combined participant observations and qualitative interviews. RESULTS: Based on the observations, the main themes for the interviews were established. Residents indicated to be free to make independent choices, and experienced less autonomy with regard to health issues and finances. Support staff stated that residents' level of autonomy depends on residents' characteristics, needs, preferences, the attitude of support staff and the rules of the care institution. CONCLUSION: Residents had a clear view on their autonomy in making independent choices. Support staff is mindful of preserving residents' autonomy, which in practice is limited.

Development and applicability of a tool for identification of people with intellectual disabilities in need of palliative care (PALLI).

BACKGROUND: Timely identifying people with intellectual disabilities in need of palliative care is important. Therefore, we developed PALLI: a screening tool for deteriorating health, indicative of a limited life expectancy. Here, we aimed to describe development of PALLI and to explore its applicability. METHOD: We used a five-stage mixed-methods procedure to develop PALLI based on knowledge from practice. For exploring applicability, professionals caring for people with intellectual disabilities completed PALLI for 185 people with intellectual disabilities and provided information on applicability after 5-6 months. RESULTS: The final version of PALLI included 39 questions relevant for people with intellectual disabilities. Applicability was adequate: Most professionals found PALLI relevant and reported no ambiguous questions. Added value of PALLI was reflecting on and becoming aware of the process of decline in health. CONCLUSIONS: PALLI shows promising applicability and has potential as a tool for timely identifying people with intellectual disabilities who may benefit from palliative care.

Biochemical measures and frailty in people with intellectual disabilities.

INTRODUCTION: People with intellectual disabilities (ID) are earlier frail than people in the general population. Although this may be explained by lifelong unfavourable social, psychological and clinical causes, underlying physiological pathways might be considered too. Biological measures can help identify pathophysiological pathways. Therefore, we examined the association between frailty and a range of serum markers on inflammation, anaemia, the metabolic system, micronutrients and renal functioning. METHODS: Participants (n = 757) with borderline to severe ID (50+) were recruited from three Dutch ID care and support services. RESULTS: Frailty was measured with a frailty index, a measure based on the accumulation of deficits. Linear regression analyses were performed to identify associations between frailty and biochemical measures independent of age, gender, level of ID and the presence of Down syndrome. Frailty appears associated with inflammation (IL-6 and CRP), anaemia, metabolic markers (glucose, cholesterol and albumin) and renal functioning (cystatin-C and creatinine). DISCUSSION: These results are in line with results observed in the general population. Future research needs to investigate the causal relation between biochemical measures and frailty, with a special focus on inflammation and nutrition. Furthermore, the possibility to screen for frailty using biochemical measures needs to be used.

[Frailty in people with intellectual disabilities: operationalization, risks and detection]. / Kwetsbaarheid bij ouderen met een verstandelijke beperking: operationalisering, risico en opsporing.

Although the population with intellectual disabilities (ID) is increasingly growing older, there seems to be an early onset of functional decline in this group, which could be explained by frailty. We used data from the Healthy Aging and Intellectual Disability study (HA-ID) to measure frailty in people with ID. Frailty was measured with an adapted version of the frailty index, consisting of 50 health and age related deficits. We were the first to measure frailty with a frailty index in this population, and therefore its validity, in terms of predictive value, needed to be established. In the current article we provide an overview of the design of the frailty index and its relation with adverse health outcomes. In a nearly representative study population of 982 50-plus older adults with ID, we studied the prevalence of frailty and its validity over a 3-year follow-up period. Results show that people with ID were earlier and more severely frail than people from the general population. Frailty was related to early mortality, to disabilities in daily functioning and mobility, to increased medication use, and increased care intensity, but not to hospitalization. Using a hypothetical model, we identify possible interventions to increase the healthy life years in people with ID.

Development and evaluation of a structured programme for promoting physical activity among seniors with intellectual disabilities: a study protocol for a cluster randomized trial.

BACKGROUND: Older people with intellectual disabilities have very low physical activity levels. Well designed, theory-driven and evidence-based health promotion programmes for the target population are lacking. This paper describes the design of a cluster-randomised trial for a systematically developed health promotion programme aimed at improving physical activity and increasing fitness among seniors with intellectual disabilities. METHODS AND DESIGN: The Intervention Mapping protocol was used for programme development. After defining the programme's objectives, the following behavioural techniques were selected to achieve them: Tailoring, Education, Modelling, Mirroring, Feedback, Reinforcement and Grading. With professionals and managers of provider services for people with intellectual disabilities, we translated these strategies into a structured day-activity programme, that consisted of a physical activity and an education programme. The programme will be executed in five day-activity centres in groups of eight to ten seniors during eight months, whereas seniors in five other centres receive care as usual. The physical activity level, as measured in number of steps a day, will be used as primary outcome measurement. Secondary outcome measurements include motor fitness, cardio respiratory fitness, morphological and metabolic fitness, ADL, functional deterioration and depressive symptoms. Differences in the primary and secondary outcome measures between participants and controls will be analysed using generalized estimation equations, correcting for day-activity center as cluster. DISCUSSION: This paper provides insight into the development and content of a theory-driven intervention aimed at behavioural change in a population with a low intellectual level. Its evaluation design is described. The programme's applicability to other populations is discussed.

GPs' recognition of death in the foreseeable future and diagnosis of a fatal condition: a national survey.

BACKGROUND: Nowadays, palliative care is considered as a care continuum that may start early in the course of the disease. In order to address the evolving needs of patients for palliative care in time, GPs should be aware in good time of the diagnosis and of the imminence of death. The aim of the study was to gain insight into how long before a non-sudden death the diagnosis of the disease ultimately leading to death is made and on what kind of information the diagnosis is based. In addition, we aimed to explore when, and based on what kind of information, GPs become aware that death of a patient will be in the foreseeable future. METHODS: A written questionnaire focusing on the GPs' experiences with their last patient who died non-suddenly was sent to a random representative sample of 850 GPs in the Netherlands. RESULTS: The data were analysed of the 297 GPs who responded. 76% of the reported cases were cancer patients and 24% were patients with another non-sudden cause of death. The diagnosis was made only in the last week of life for 15% of the non-cancer patients and 1% of the patients with cancer. GPs were most likely to have been informed of the diagnosis by the medical specialist, although particularly in the case of non-cancer patients GPs also relied on their own assessment of the diagnosis or on other information sources.The GP remained unaware that the patient would die in the foreseeable future until the last week of life in 26% of the non-cancer group, while this was the case for only 6% of the cancer patients. GP's awareness was most likely to be based on the GP's own observations of problems and/or symptoms. CONCLUSIONS: The GP often only becomes aware of a fatal diagnosis and of death in the foreseeable future at a late stage in the disease trajectory, particularly in the case of non-cancer patients. It can be assumed that if the diagnosis and the nearing death are only recognised at a late stage, palliative care is either started at a very late stage or not at all.

Comparison of two types of Actiwatch with polysomnography in older adults with intellectual disability: a pilot study.

BACKGROUND: The Actiwatch is increasingly being used to investigate sleep. The aim of this study was to investigate which sensitivity setting of the Actiwatch is most suitable to detect sleep disturbance in older adults with intellectual disability (ID). METHOD: Two Actiwatch types were compared to polysomnography (PSG) in 10 older adults with mild ID, using a 1-min epoch-to-epoch comparison. Outcome measures were sleep detection percentage, wake detection percentage, and overall accuracy of both Actiwatches, and several sleep parameters. RESULTS: The high sensitivity setting of the Actiwatch appeared most suitable to detect sleep disturbance in older adults with ID (wake detection percentage = 54.6%, sleep detection percentage = 89.7%). Sleep parameters calculated using the high sensitivity setting corresponded well to PSG outcomes. Outcomes were similar for both Actiwatches. CONCLUSIONS: We recommend using the high sensitivity setting of the Actiwatch for clinical evaluation of sleep, and for epidemiological research in older adults with ID.

Enhancing patient-reported outcome measurement in research and practice of palliative and end-of-life care.

PURPOSE: Patient-reported outcome measurement (PROM) plays an increasing role in palliative and end-of-life (EOL) care but their use in EOL care and research remains varied and inconsistent. We aimed to facilitate pan-European collaboration to improve PROMs in palliative and EOL care and research. METHODS: The study includes a workshop with experts experienced in using PROMs in clinical care and research from Europe, North America, and Africa. Information from presentations, and plenary and group discussions was analysed using content analysis for extracting the main themes. RESULTS: Thirty-two professionals from 15 countries and eight different professional backgrounds participated in the workshop. The discussion identified: 1) the need for standardisation with improvement of existing PROMs, e.g., with a modular system and an optional item pool; 2) the aspects of further development with a multi-professional approach taking into account cultural sensitivity especially for translated versions; and 3) the need for guidance, training, and resources. An international network for sharing concepts, experiences, and solutions could enhance these steps of further development. CONCLUSION: PROMs must be based on rigorous scientific methods and respond to patient complexity. Coordinated pan-European collaboration including researchers and clinicians is required to develop and attain quality care and systematic research in outcome measurement in palliative and EOL care.

Nurse Leadership and Work Environment Association with Outcome Expectancy and Self-Efficacy in Evidence-Based Practice among Hospital Nurses in The Netherlands: A Cross-Sectional Study.

The active participation of nurses in evidence-based practice (EBP) is challenging and topical, as shown by the worldwide calls for appropriate, accessible, affordable care and the de-implementation of unnecessary care. Nurses' perceived support from their managers and work environments may affect their self-efficacy and outcome expectancy in EBP, as well as hinder them in EBP. Associations between these issues have not yet been explored. This study examines the association of self-efficacy and outcome expectancy levels in EBP, as well as the perceived support for EBP from nurse leaders and in the working environment, among Dutch hospital nurses. METHODS: Questionnaires measuring nurses' self-efficacy, outcome expectancy, and perceived support for EBP from nurse leaders and their work environment were completed by 306 nurses in eight hospitals between March 2021 and June 2021. We used multilevel regression analyses to determine the associations and covariates. RESULTS: This study shows that EBP-supportive leaders and work environments positively contribute to nurses' self-efficacy and outcome expectancy in EBP, along with the covariates undertaking EBP activities and educational level. CONCLUSIONS: To improve nurses' active participation in EBP, nurses need to increase their self-efficacy and outcome expectancy in EBP. Supportive leaders and a supportive work environment do have an impact. Hence, these factors need attention when implementing EBP among nurses.

The oldest old and GP end-of-life care in the Dutch community: a nationwide study.

BACKGROUND: Provision of adequate care for the oldest old is increasingly crucial, given the current ageing trends. This study explores differences in end-of-life care of the oldest (≥85 years) versus the younger (65-84 years) old; testing the hypothesis that age could be an independent correlate of receiving specialised palliative care services (SPCS), having palliative-centred treatment and dying in a preferred place. METHODS: general practitioners (GPs) participating in the nation-wide representative network in the Netherlands were asked to fill in patient, illness and care characteristics of all registered patients ≥65 years, who died non-suddenly in their practices between 2005 and 2008, using standardised forms. Associations with the palliative care variables were tested using multiple logistic regression. RESULTS: nine hundred and ninety patients were registered. Among the oldest old, there were more women than men, more patients with heart failure than cancer, less hospital and home deaths and more residential care home deaths compared with the younger old. Of the oldest old, fewer received SPCS and more preferred to die in a residential care home than the younger old. Age was independently associated with palliative care provided: compared with the younger group, the oldest old received SPCS less often (OR = 0.7) and were treated with a palliative-centred goal more often (OR = 2.4); but age was not related to dying in a preferred place, i.e. independent of other characteristics. CONCLUSION: this study shows age to be independently associated with receiving SPCS in the Dutch community. Although the GPs do recognise the 'palliative phase' in the oldest old, involvement of specialist teams is somewhat less.

Evaluation of quality-of-life measures for use in palliative care: a systematic review.

PURPOSE: In this literature review we evaluated the feasibility and clinimetric quality of quality-of-life (QoL) measurement instruments suitable for use in palliative care. METHODS: We conducted a systematic literature review to identify instruments measuring (at least one domain of) QoL. We selected articles that present data on patients receiving palliative care and at least one measurement property. A checklist was used to describe the characteristics of the instruments, and a widely accepted rating list was used to evaluate the clinimetric aspects. RESULTS: 29 instruments were identified and evaluated, most of which were targeted at palliative patients in general. None of the instruments demonstrated satisfactory results for all measurement properties. Fourteen instruments received positive ratings for construct validity. Thirteen instruments were tested for reliability, but only two were tested adequately and had positive results (ICC>0.70). Responsiveness was not tested adequately for any of the instruments. Very few of the studies provided information on the interpretation of the scores. Overall, the MQOL, followed by the QUAL-E and the QODD, received the best ratings for their measurement properties. CONCLUSIONS: Many measurement instruments were identified, but most had not yet been adequately evaluated. The evaluation of existing instruments with good content validity should have priority over the development of new instruments.

Validation of the Dutch version of the Edmonton Symptom Assessment System.

BACKGROUND: The Utrecht Symptom Diary (USD) is a Dutch and adapted version of the Edmonton Symptom Assessment System, a patient-reported outcome measurement (PROM) tool to asses and monitor symptoms in cancer patients. This study analyses the validity and responsiveness of the USD and the cutoff points to determine the clinical significance of a symptom score. METHODS: Observational longitudinal cohort study including adult in- and outpatients treated in an academic hospital in the Netherlands who completed at least one USD as part of routine care (2012-2019). The distress thermometer and problem checklist (DT&PC) was used as a reference PROM. Content, construct and criterion validity, responsiveness, and cutoff points are shown with prevalences, area under receiver operating characteristic (ROC) curve, Chi-squared test, Wilcoxon signed-rank test, and positive and negative predictive values, respectively. RESULTS: A total of 3913 patients completed 22 400 USDs. Content validity was confirmed for all added USD items with prevalences of ≥22%. All USD items also present on the DT&PC demonstrated a good criterion validity (ROC >0.8). Construct validity was confirmed for the USD as a whole and for the items dry mouth, dysphagia and well-being (P < .0001). USD scores differed significantly for patients when improving or deteriorating on the DT&PC which confirmed responsiveness. Optimal cutoff points (3 or 4) differed per symptom. CONCLUSION: The USD is a valid 12-item PROM for the most prevalent symptoms in cancer patients, which has content, criterion, and construct validity, and detects clinically important changes over time, in both curative and palliative phase.

Multidimensional fatigue and its correlates in hospitalised advanced cancer patients.

Although fatigue is a multidimensional concept, multidimensional fatigue is rarely investigated in hospitalised cancer patients. We determined the levels and correlates of multidimensional fatigue in 100 advanced cancer patients admitted for symptom control. Fatigue dimensions were general fatigue (GF), physical fatigue (PF), reduced activity (RA), reduced motivation (RM) and mental fatigue (MF). Investigated correlates were tumour load, prior anti-tumour treatment, medication use, haemoglobin levels, serum biochemical variables, physical symptoms and mood. Median GF, PF and RA scores were very high; median RM and MF scores were moderate, and differed from the GF, PF and RA scores. Multiple regression analyses showed that symptoms and mood correlated with all fatigue dimensions. Each fatigue dimension had different relationships with other factors. Hospitalised advanced cancer patients differ in fatigue levels depending on the fatigue dimension, and each fatigue dimension has different correlates. The results confirm that fatigue should be regarded as a multidimensional concept.

Analgesic adherence measurement in cancer patients: comparison between electronic monitoring and diary.

Adherence to analgesics in cancer patients has scarcely been studied. In this study, the Medication Event Monitoring System (MEMS) and medication diaries were compared with respect to feasibility and adherence measurements. Forty-six outpatients with nociceptive pain caused by cancer were asked to use MEMS for their analgesics and to record their medication usage in a diary for four weeks. Seventy-nine percent of the patients used MEMS for the full four-week period; 70% did so for the diary. The majority of patients were satisfied with both MEMS and diary. Adherence data assessed by MEMS and diary were comparable. Patients used the amount of analgesics adequately (taking adherence: 87%) but took them irregularly (timing adherence: 53%). Subgroup analyses in patients using single and multiple analgesic regimens confirmed the comparable suitability of both methods. MEMS and a medication diary are equally useful for analgesic adherence measurement in cancer patients with pain.

Comparing two frailty concepts among older people with intellectual disabilities.

In general, disabilities are considered a consequence of frailty rather than a cause of frailty, whereas in people with intellectual disabilities (ID), disabilities are often lifelong, which could have consequences for the feasibility and validity of frailty instruments. To better understand frailty in people with ID, we compared two broadly used concepts: the frailty phenotype (FP) and the frailty index (FI) taking into account their feasibility (e.g., percentage of participants able to complete the frailty assessments), agreement, validity (based on 5-year mortality risk), influence of motor disability, and the relation between single frailty variables and mortality. The FI and an adapted version of the FP were applied to a representative dataset of 1050 people with ID, aged 50 years and over. The FI was feasible in a larger part of the dataset (94 %) than the adapted FP: 29 % for all five items, and 81 % for at least three items. There was a slight agreement between the approaches (κ = 0.3). However defined, frailty was related with mortality, but the FI showed higher discriminative ability and a stronger relation with mortality, especially when adjusted for motor disabilities. Concluding, these results imply that the used FI is a stronger predictor for mortality and has higher feasibility than our adaptation of the FP, in older people with ID. Possible explanations of our findings are that we did not use the exact FP variables or that the FI includes multiple health domains, and the variables of the FI have lower sensitivity to lifelong disabilities and are less determined by mobility.

Construct validity and responsiveness of Movakic: An instrument for the evaluation of motor abilities in children with severe multiple disabilities.

Movakic is a newly developed instrument for measurement of motor abilities in children with severe multiple disabilities, with a satisfactory feasibility and content validity and good inter-observer and test-retest reliability. The objective of this study was to investigate its construct validity and responsiveness to change. Sixty children with severe multiple disabilities (mean age 7.7 years, range 2-16) were measured using Movakic six times during 18 months. Construct validity was assessed by correlating Movakic scores with expert judgment. In order to assess responsiveness, scores during 3-months intervals were compared (mean score-changes and intraclass correlations) during which some children experienced meaningful events influencing motor abilities and during which others experienced no such event. Forty-five percent of children had a lower cognitive development level than 6-month, 52% had Gross Motor Function Classification System level V and 37% had level IV. For 27 children all measurements were completed, six children dropped out. Construct validity was good (r=0.50-0.71). Responsiveness was demonstrated by significantly larger score changes after events than when such events did not occur. Movakic is a valid instrument for measuring motor abilities in children with severe multiple disabilities. Results suggest responsiveness to change in motor abilities after meaningful events.

Physician-Reported Symptoms and Interventions in People with Intellectual Disabilities Approaching End of Life.

BACKGROUND: Insights into symptoms and interventions at the end of life are needed for providing adequate palliative care, but are largely lacking for people with intellectual disabilities (IDs). OBJECTIVES: We aimed at determining the prevalence rates of physician-reported symptoms from the Edmonton Symptom Assessment System (ESAS) at the moment that physicians recognized patient's death in the foreseeable future. In addition, we aimed at exploring provided interventions as reported by physicians in the period between physicians' recognition of death in the foreseeable future and patients' death. MEASUREMENTS: In this study, 81 physicians for people with IDs (ID-physicians) completed a retrospective survey about their last patient with IDs with a nonsudden death. RESULTS: On average, patients suffered from three of the eight ESAS symptoms. Fatigue (83%), drowsiness (65%), and decreasing intake (57%) were most reported. ID-physicians reported a median number of four interventions. Interventions were mostly aimed at somatic problems, such as pain and shortness of breath. Burdensome interventions such as surgery or artificial respiration were least or not reported. Palliative sedation was provided in a third of all cases. CONCLUSION: Although ID-physicians reported a variety of their patients' symptoms and of provided interventions at the end of life, using adequate symptom assessment tools suitable for people with IDs and continuous multidisciplinary collaboration in palliative care are essential to capture symptoms as fully as possible.

Instruments for the evaluation of motor abilities for children with severe multiple disabilities: A systematic review of the literature.

Based on a systematic review, psychometric characteristics of currently available instruments on motor abilities of children with disabilities were evaluated, with the aim to identify candidates for use in children with severe multiple (intellectual and motor) disabilities. In addition, motor abilities are essential for independent functioning, but are severely compromised in these children. The methodological quality of all studies was evaluated with the Consensus Based Standards for the Selection of Health Status Measurement Instruments (COSMIN) Checklist; overall levels of evidence per instrument were based on the Cochrane Back Review Group strategy. As a result, 18 studies with a total of eight instruments, developed for children with cerebral palsy (CLA, GMFM-88 and LE85), spinal muscular atrophy (MHFMS), neuromuscular diseases (MFM), disabilities 0-6 years (VAB, WeeFIM), and one developed specifically for children with severe multiple disabilities (TDMMT) were found. Strong levels of evidence were found for construct validity of LE85 and MFM and for responsiveness of WeeFIM, but reliability studies of these instruments had a limited methodological quality. Up to now studies of the TDMMT resulted in limited and unknown evidence for structural validity due to the poor methodological quality of reliability studies. In a next step, the clinical suitability of the instruments for children with severe multiple disabilities will be evaluate.

The use of a frailty index to predict adverse health outcomes (falls, fractures, hospitalization, medication use, comorbid conditions) in people with intellectual disabilities.

Frailty in older people can be seen as the increased likelihood of future negative health outcomes. Lifelong disabilities in people with intellectual disabilities (ID) may not only influence their frailty status but also the consequences. Here, we report the relation between frailty and adverse health outcomes in older people with ID (50 years and over). In a prospective population based study, frailty was measured at baseline with a frailty index in 982 older adults with ID (≥50 yr). Information on negative health outcomes (falls, fractures, hospitalization, increased medication use, and comorbid conditions) was collected at baseline and after a three-year follow-up period. Odds ratios or regression coefficients for negative health outcomes were estimated with the frailty index, adjusted for gender, age, level of ID, Down syndrome and baseline adverse health condition. The frailty index was related to an increased risk of higher medication use and several comorbid conditions, but not to falls, fractures and hospitalization. Frailty at baseline was related to negative health outcomes three years later in older people with ID, but to a lesser extent than found in the general population.
