Potentially inappropriate medications in nursing homes and the community older adults using the French health insurance databases.

PURPOSE: Potentially inappropriate medications (PIMs) have become a major issue in improving prescribing practices and reducing the risk of adverse drug events in older people. However, very few studies have compared exposition to PIMs controlling for differences in demographic and health between nursing home residents (NHRs) and community-dwelling older adults (CDOAs). This study aimed to assess the prescribing pattern of PIMs between NHRs and CDOAs. METHODS: We conducted a cross-sectional study over three months in 2019 using the French Health Insurance databases. The study population included 274 971 NHRs and 4 893 721 CDOAs aged 75 years or over. The prevalence ratio (PR) between NHRs and CDOAs of 17 PIM indicators, based on the Beers and STOPP criteria lists, was assessed using multivariable robust Poisson regression adjusted for age, sex, diseases, and polypharmacy. RESULTS: During the study period, 54% of NHRs and 29% of CDOAs received at least one PIM. After adjustment, the prevalence of PIMs was 33% higher among NHRs compared to CDOAs (aPR = 1.33; 95% CI [1.33-1.34]). NHRs received PIMs related to benzodiazepines (aPR = 1.43; 95% CI [1.42-1.43]), anticholinergic drugs (aPR = 1.29; 95% CI [1.27-1.31]), and at least three central nervous system-active drugs (aPR = 1.94; 95% CI [1.92-1.96]) more frequently. Prevalence of PIMs related to non-steroidal anti-inflammatory drugs (aPR = 0.50; 95% CI [0.48-0.52]) and long-acting benzodiazepines (aPR = 0.84; 95% CI [0.82-0.85]) was lower among NHRs. CONCLUSION: The NHRs were at greater risk for PIM than CDOAs, although differences exist according to the category of PIMs. As the population is aging, it is essential to promote and evaluate interventions in NHs and the community to enhance medication optimization.

Uses and perceptions of medications among French older adults: results from the 2020 French Health Barometer survey.

BACKGROUND: There are few studies reporting on self-medication, perceptions or difficulties older adults have with their medications. This study aimed to describe the uses and the perceptions of medications among older adults in France and to identify patient groups based on that information. METHODS: We used data from the 2020 'French Health Barometer' - a nationally-representative cross-sectional survey. We assessed polypharmacy (five or more medications), self-medication, and patient perceptions of medications. Robust Poisson regression was used to investigate socio-demographic and health-related factors associated with the outcomes. Latent class analysis was used to identify patient groups classified by the use and the perceptions of medications. Factors associated with group assignment were investigated by multinomial logistic regression. All analyses were weighted. RESULTS: The study sample comprised 1,623 respondents aged 70-85 years. Polypharmacy and self-medication were reported in 23.5 and 48.7% of the older population, respectively. Polypharmacy was associated with increasing age, low education, and impaired health status. Self-medication was associated with female sex and high education. Among individuals taking at least 1 medication, 8.2% reported not to understand all their medications, and 9.7% having difficulty taking medications as prescribed. Among individuals taking at least 2 medications, 23.2% thought that they took too many medications. Three patient groups were identified: 'Non-polypharmacy, positive perceptions' (62.5%), 'Polypharmacy, positive perceptions' (28.0%), and 'Negative perceptions' (9.5%). CONCLUSIONS: Polypharmacy and self-medication are common in French older adults. One segment of people reported negative perceptions of their medications regardless of their polypharmacy status. This underlines the difference between the objective and perceived measures of polypharmacy.

Treatment for multiple myeloma in hospital at home: clinical characteristics and patient care pathways.

While most patients receive anticancer injection in a conventional hospital, some are treated in hospital at home. Given the lack of data, we seek to determine the clinical characteristics and care pathways of patients benefiting from hospital at home (HAH) for anticancer injection. A longitudinal scheme was conducted about patients with multiple myeloma (MM) starting bortezomib-based regimens in HAH in 2015 with a follow-up to September 2019. 154 patients received bortezomib at home with a mean age of 70.6 years, 72.7% over 65y-old and, a median Karnofsky Performans Status of 70. One-third of the elderly lived alone, 16.1% required domestic help. After a 24-month follow-up, 77.9% of patients were alive. The median overall survival was not reached at 4 years. Between 42.1% and 48.1% of patients returned to HAH for a new line of treatment. Patients were mainly independent and "fit." The involvement of HAH was achieved without safety issues nor compromise long-term outcomes. However, the real-world patterns highlighted that only a small proportion of patients returned to HAH for a new treatment line.

Impacts on health outcomes and on resources utilization for anticancer drugs injection at home, a complex intervention: a systematic review.

BACKGROUND: As hospital-based home care is a complex intervention, we critically appraised the key elements that could ensure the completeness of assessment and explain the heterogeneity of the literature results about the comparison between home and hospital setting for the anticancer drugs injection within the same standards of clinical care. METHODS: Systematic review was conducted. Medline, Embase, Cochrane Library, Web of Sciences, and Cumulative Index of Nursing and Allied Health (Cinahl) searched to February 1, 2019, and combined with grey literature. Methodological quality has been rated using the "Quality Assessment Tool for Quantitative Studies" developed by the Effective Public Health Practice Project (EPHHP) in addition to the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement for economic studies and the consolidated criteria for reporting qualitative research (COREQ) checklist for qualitative studies. RESULTS: Of 400 records identified, we identified 13 relevant studies (nine quantitative and four mixed-method studies). The quality of studies was hardly strong. The home-based anticancer injection involved highly heterogeneous home care interventions that generally kept a strong link with the hospital setting. The study schemes limited the comparison of clinical outcomes (OS, PFS, toxicity). Unlike the quality of life remaining similar, patients preferred to be treated at home. Cost savings were in favor of Hospital at Home, but the charge categories used to compare or the home intervention were heterogeneous and rarely integrating relatives' duties and hospital staff's time. Qualitative studies highlighted about benefits and barriers of home. CONCLUSION: The current state of evidence shows as it still remains difficult to appraise the anticancer injection at home when considering the details of this complex intervention, the role of each stakeholder, and the missing data.

Decreasing trends in potentially inappropriate medications in older people: a nationwide repeated cross-sectional study.

BACKGROUND: Potentially Inappropriate Medications (PIMs) and polypharmacy are widely used indicators of suboptimal prescribing for older people. The aim of this study was to describe the changes in the prevalence of PIMs and polypharmacy among people aged 75 years and over between 2011 and 2019 in France. METHODS: PIMs and polypharmacy were assessed among people aged 75 years and over every two years between 2011 and 2019 using the French health insurance data system. Sixteen PIM criteria from the 2015 Beers and STOPP lists were assessed. Polypharmacy (5 to 9 drugs) and hyper-polypharmacy (≥10 drugs) were defined based on the average number of drugs dispensed per quarter. The Annual Percent Change (APC) and 95%CI were assessed using linear regression models after standardization of the prevalence on age and sex. RESULTS: The study population included 5,777,645 individuals over 75 years old in 2011 and 6,328,155 in 2019. The prevalence of PIMs decreased from 49.6 to 39.6% over the study period (APC: - 1.19% [- 1.35;-1.04]). Of the sixteen indicators assessed, the prevalence of thirteen decreased between 2011 and 2019. Benzodiazepines were the most frequent PIMs (34.7% in 2011 to 26.9% in 2019), followed by anticholinergic drugs (12.1% in 2011 to 8.3% in 2019), oral non-steroidal anti-inflammatory drugs (11.4 to 7.8%), and PIMs related to antihypertensive drugs (7.4 to 6.0%). Overall, women and individuals aged 85 years and older were more likely to receive PIMs. The prevalence of hyper-polypharmacy decreased from 30.5 to 25.9% over the study period. CONCLUSION: This study, which is the first to assess the change in prevalence of PIMs and polypharmacy over time from comprehensive health data in France, highlights that PIMs and hyper-polypharmacy declined between 2011 and 2019. However, PIMs remains frequent for older people and often involves benzodiazepines.

Frailty and Associated Factors among Centenarians in the 5-COOP Countries.

BACKGROUND: The global number of centenarians is still strongly growing and information about the health and healthcare needs of this segment of the population is needed. This study aimed to estimate the prevalence of frailty among centenarians included in a multinational study and to investigate associated factors. METHODS: The 5-COOP study is a cross-sectional survey including 1,253 centenarians in 5 countries (Japan, France, Switzerland, Denmark, and Sweden). Data were collected using a standardized questionnaire during a face-to-face interview (73.3%), telephone interview (14.5%), or by postal questionnaire (12.2%). The 5 dimensions of the frailty phenotype (weight loss, fatigue, weakness, slow walking speed, and low level of physical activity) were assessed by using self-reported data. Factors associated with frailty criteria were investigated by using multivariate regression models. RESULTS: Almost 95% of the participants had at least 1 frailty criterion. The overall prevalence of frailty (3 criteria or more) was 64.7% (from 51.5% in Sweden to 77.6% in Switzerland), and 32.2% of the participants had 4 or 5 criteria. The most frequent criteria were weakness (84.2%), slow walking speed (77.6%), and low level of physical activity (72.5%), followed by fatigue (43.8%) and weight loss (23.8%). Factors associated with frailty included data collection modes, country of residence, gender, living in institution, depression, dementia, disability, falls, and sensory impairments. CONCLUSIONS: This study shows that reaching 100 years of age rarely goes without frailty and sheds light on factors associated with frailty at a very old age.

Potentially inappropriate prescription of antidepressants in old people: characteristics, associated factors, and impact on mortality.

ABSTRACTBackground:The increasing use of antidepressants (ADs) has raised concerns about their inappropriate use in old people. OBJECTIVE: To examine the prevalence of potentially inappropriate prescribing (PIP) of ADs, their associated factors, and their impact on mortality in a sample of old people in France. METHODS: The analysis used data from the SIPAF study, a cross-sectional study consisting of 2,350 people aged ≥ 70 years. Trained nurses interviewed participants at home between 2008 and 2010. Information was collected concerning socio-demographic and health characteristics, including medication use. The study population consisted of the 318 AD users from the SIPAF study (13.5%). PIP of ADs was defined according to national and international criteria. Factors associated with PIP of ADs were assessed using a multivariate logistic regression model. The influence of PIP of ADs on mortality was assessed using a Cox model (median follow-up 2.8 years). RESULTS: Among the SIPAF study, 71% of AD users were female and the mean age was 84 ± 7 years. Selective serotonin reuptake inhibitors (SSRIs) were the most prescribed ADs (19.8%). We found PIP of ADs in 36.8% of the study population, mainly the co-prescription of diuretics with SSRIs (17.6%) and the prescription of tricyclics (12.9%). PIP of ADs was associated with polypharmacy (aOR5-9 drugs 2. 61, 95% CI 1.11-6.16 and aOR≥10 drugs 2.69, 95% CI 1.06-6.87) and comorbidity (aOR3-4 chronic diseases 2.59, 95%CI 1.04-6.44 and aOR≥5 chronic diseases 2.33, 95%CI 0.94-5.79), and increased the risk of mortality during follow-up (aHR 2.30, 95%CI 1.28-4.12). CONCLUSIONS: This study shows that more than one third of AD prescriptions may be inappropriate in old people. PIP of ADs was related to polypharmacy and comorbidity and increased mortality among AD users.

Polypharmacy and potentially inappropriate medications: a cross-sectional analysis among 451 nursing homes in France.

PURPOSE: The quality of drug therapy is an important issue for nursing homes. This study aimed to assess the prevalence of polypharmacy and potentially inappropriate medications (PIMs) in a large sample of nursing home residents by using the data recorded during the preparation of pill dispensers. METHODS: This is a cross-sectional study that included 451 nursing homes across France. Information about the medications received by the 30,702 residents (73.8% women) living in these nursing homes was extracted from the system that assists in the preparation of pill dispensers in pharmacies. The anonymized database included age, sex, and medications prescribed to residents, as well as nursing home characteristics (capacity, legal status). Factors associated with excessive polypharmacy (≥10 different drugs) and PIMs according to the Laroche list were studied using multilevel regression models. RESULTS: The average number of drugs prescribed was 6.9 ± 3.3, and excessive polypharmacy concerned 21.1% of the residents (n = 6468). According to the Laroche list, 47.4% of residents (n = 14,547) received at least one PIM. Benzodiazepines (excessive doses, long-acting benzodiazepines, and combination of benzodiazepines) and anticholinergic medications (hydroxyzine, cyamemazine, alimemazine) accounted for a large part of PIMs. Individual characteristics (age, gender) influenced the risk of receiving PIMs whereas nursing home characteristics (capacity, legal status) influenced the risk of excessive polypharmacy. CONCLUSIONS: This study shows that polypharmacy and PIMs remain highly prevalent among nursing home residents. Main PIMs concerned psychotropic and anticholinergic medications.

Polypharmacy and frailty: prevalence, relationship, and impact on mortality in a French sample of 2350 old people.

PURPOSE: To assess the prevalence of polypharmacy and frailty, to examine their association, and to establish their independent and combined effects on mortality in a sample of French old people. METHODS: This is a cross-sectional population study of people aged 70 years and over. A total of 2350 respondents were interviewed at home in 2008-2010. Frailty was defined as impairment in three domains or more among nutrition, energy, physical activity, strength, and mobility, in the absence of difficulties in basic activities of daily living. Mortality data were documented after a mean follow-up period of 2.6 years. RESULTS: Mean age of the population was 83.3 +/- 7.5 years, with 59.4% of women. Prevalence of frailty was 17.0%. Polypharmacy (5-9 drugs) was reported in 53.6% of the population, and excessive polypharmacy (10 drugs or more) in 13.8%. After adjustment for socio-demographic and health variables, polypharmacy and excessive polypharmacy were associated with frailty with odds ratio 1.77 [1.20-2.61] and 4.47 [2.37-8.42], respectively. Frailty (hazard ratio [HR] 2.56 [1.63-4.04]) and excessive polypharmacy (HR 1.83 [1.28-2.62]) were independent predictors of mortality. Compared with non-frail people without polypharmacy, frail people with excessive polypharmacy were six times more likely to die during the follow-up period (HR 6.30 [3.09-12.84]). CONCLUSION: By showing the independent and combined effects of polypharmacy and frailty on mortality risk, this study should reinforce the awareness of clinicians with regard to these factors, rather prevalent in old people.

Unmet health care needs of older people: prevalence and predictors in a French cross-sectional survey.

BACKGROUND: Unmet health care needs are associated with negative health outcomes, yet there is a paucity of data on this problem among older people. OBJECTIVE: To identify unmet health care needs and associated factors among older people in France. METHODS: This is a cross-sectional population study of people aged 70 years or older in which 2350 respondents were interviewed in 2008-10. During a standardized interview, a nurse examined health problems, functional abilities and use of health care resources. Unmet health care needs were defined as situations in which a participant needed health care and did not receive it. RESULTS: The mean age was 83.2 ± 7.4 years. Almost all participants reporting a chronic disease (98.6%) had consulted a physician in the previous 6 months. Unmet health care needs were found in 23.0% of the sample and mainly consisted of lack of dental care (prevalence of 17.7%), followed by lack of management of visual or hearing impairments (prevalence of 4.4% and 3.1%, respectively). Age was the main factor associated with unmet health care needs [compared with people aged 70-79: odds ratio80-89 years = 2.26 (1.70-3.03), odds ratio90 years and over = 3.85 (2.71-5.45)]. Other associated factors were regular smoking, homebound status, poor socioeconomic conditions, depression, limitations in instrumental activities of daily living and low medical density. CONCLUSION: Unmet health care needs affect almost one-quarter of older people in France. Efforts should be made to improve oral health and develop home care, especially for the oldest-olds.

Multidisciplinary teams of case managers in the implementation of an innovative integrated services delivery for the elderly in France.

BACKGROUND: The case management process is now well defined, and teams of case managers have been implemented in integrated services delivery. However, little is known about the role played by the team of case managers and the value in having multidisciplinary case management teams. The objectives were to develop a fuller understanding of the role played by the case manager team and identify the value of inter-professional collaboration in multidisciplinary teams during the implementation of an innovative integrated service in France. METHODS: We conducted a qualitative study with focus groups comprising 14 multidisciplinary teams for a total of 59 case managers, six months after their recruitment to the MAIA program (Maison Autonomie Integration Alzheimer). RESULTS: Most of the case managers saw themselves as being part of a team of case managers (91.5%). Case management teams help case managers develop a comprehensive understanding of the integration concept, meet the complex needs of elderly people and change their professional practices. Multidisciplinary case management teams add value by helping case managers move from theory to practice, by encouraging them develop a comprehensive clinical vision, and by initiating the interdisciplinary approach. CONCLUSIONS: The multidisciplinary team of case managers is central to the implementation of case management and helps case managers develop their new role and a core inter-professional competency.

Artificial intelligence integration in the drug lifecycle and in regulatory science: policy implications, challenges and opportunities.

Artificial intelligence tools promise transformative impacts in drug development. Regulatory agencies face challenges in integrating AI while ensuring reliability and safety in clinical trial approvals, drug marketing authorizations, and post-market surveillance. Incorporating these technologies into the existing regulatory framework and agency practices poses notable challenges, particularly in evaluating the data and models employed for these purposes. Rapid adaptation of regulations and internal processes is essential for agencies to keep pace with innovation, though achieving this requires collective stakeholder collaboration. This article thus delves into the need for adaptations of regulations throughout the drug development lifecycle, as well as the utilization of AI within internal processes of medicine agencies.

Economic analysis of the intangible impacts of informal care for people with Alzheimer's disease and other mental disorders.

OBJECTIVES: Valuation of the intangible impacts of informal care remains a great challenge for economic evaluation, especially in the framework of care recipients with cognitive impairment. Our main objective was to explore the influence of intangible impacts of caring on both informal caregivers' ability to estimate their willingness to pay (WTP) to be replaced and their WTP value. METHODS: We mapped characteristics that influence ability or inability to estimate WTP by using a multiple correspondence analysis. We ran a bivariate probit model with sample selection to further analyze the caregivers' WTP value conditional on their ability to estimate their WTP. RESULTS: A distinction exists between the opportunity costs of the caring dimension and those of the intangible costs and benefits of caring. Informal caregivers' ability to estimate WTP is negatively influenced by both intangible benefits from caring (P < 0.001) and negative intangible impacts of caring (P < 0.05). Caregivers' WTP value is negatively associated with positive intangible impacts of informal care (P < 0.01). CONCLUSIONS: Informal caregivers' WTP and their ability to estimate WTP are both influenced by intangible burden and benefit of caring. These results call into question the relevance of a hypothetical generalized financial compensation system as the optimal way to motivate caregivers to continue providing care.

Diffusion of a collaborative care model in primary care: a longitudinal qualitative study.

BACKGROUND: Although collaborative team models (CTM) improve care processes and health outcomes, their diffusion poses challenges related to difficulties in securing their adoption by primary care clinicians (PCPs). The objectives of this study are to understand: (1) how the perceived characteristics of a CTM influenced clinicians' decision to adopt -or not- the model; and (2) the model's diffusion process. METHODS: We conducted a longitudinal case study based on the Diffusion of Innovations Theory. First, diffusion curves were developed for all 175 PCPs and 59 nurses practicing in one borough of Paris. Second, semi-structured interviews were conducted with a representative sample of 40 PCPs and 15 nurses to better understand the implementation dynamics. RESULTS: Diffusion curves showed that 3.5 years after the start of the implementation, 100% of nurses and over 80% of PCPs had adopted the CTM. The dynamics of the CTM's diffusion were different between the PCPs and the nurses. The slopes of the two curves are also distinctly different. Among the nurses, the critical mass of adopters was attained faster, since they adopted the CTM earlier and more quickly than the PCPs. Results of the semi-structured interviews showed that these differences in diffusion dynamics were mostly founded in differences between the PCPs' and the nurses' perceptions of the CTM's compatibility with norms, values and practices and its relative advantage (impact on patient management and work practices). Opinion leaders played a key role in the diffusion of the CTM among PCPs. CONCLUSION: CTM diffusion is a social phenomenon that requires a major commitment by clinicians and a willingness to take risks; the role of opinion leaders is key. Paying attention to the notion of a critical mass of adopters is essential to developing implementation strategies that will accelerate the adoption process by clinicians.

Midlife stroke risk and cognitive decline: a 10-year follow-up of the Whitehall II cohort study.

BACKGROUND: Stroke is associated with an increased risk of dementia. However, it is unclear whether risk of stroke in those free of stroke, particularly in nonelderly populations, leads to differential rates of cognitive decline. Our aim was to assess whether risk of stroke in mid life is associated with cognitive decline over 10 years of follow-up. METHODS: We studied 4153 men and 1657 women (mean age, 55.6 years at baseline) from the Whitehall II study, a longitudinal British cohort study. We used the Framingham Stroke Risk Profile (FSRP), which incorporates age, sex, systolic blood pressure, diabetes mellitus, smoking, prior cardiovascular disease, atrial fibrillation, left ventricular hypertrophy, and use of antihypertensive medication. Cognitive tests included reasoning, memory, verbal fluency, and vocabulary assessed three times over 10 years. Longitudinal associations between FSRP and its components were tested using mixed-effects models, and rates of cognitive change over 10 years were estimated. RESULTS: Higher stroke risk was associated with faster decline in verbal fluency, vocabulary, and global cognition. For example, for global cognition there was a greater decline in the highest FSRP quartile (-0.25 of a standard deviation; 95% confidence interval: -0.28 to -0.21) compared with the lowest risk quartile (P = .03). No association was observed for memory and reasoning. Of the individual components of FSRP, only diabetes mellitus was associated independently with faster cognitive decline (ß = -0.06; 95% confidence interval, -0.01 to 0.003; P = .03). CONCLUSION: Elevated stroke risk at midlife is associated with accelerated cognitive decline over 10 years. Aggregation of risk factors may be especially important in this association.

[Single entry point in a gerontological network for addressing the needs of older people]. / Un guichet unique dans un réseau gérontologique pour i'orientation des personnes âgées.

INTRODUCTION: A single entry point for the elderly is important for the integration of services and for standardizing needs assessment processes. The role of a single entry point role is to refer older persons to the appropriate social and/or health services. The purpose of this paper is to describe the relationships between institutional partners and their use of the single entry point in a gerontological network. METHODS: The gerontological network "Ancrage" is one of the first integrated care models with a single entry point to be implemented in France. The contact assessment tool known as CHIP (Community Hospital Intake Profile) is used to assess the needs of elderly people living at home and to make referrals. The data collected included all the requests made by partners at the single entry point over the course of one year (2008). RESULTS: A total of 303 requests were submitted to the single entry point by all partners (i.e. health and social professionals). These requests came from primary care professionals (68.3%), notably family physicians (29.3%). The needs of elderly people varied according to the type of requester. Most of those involved were directed toward the gerontological network (59.2%) and had more complex needs (no support from an informal caregiver and more difficulties in performing daily activities). CONCLUSION: A single entry point is designed to involve all institutional partners and to meet the needs of the elderly. The level of involvement among physicians is high, and elderly people directed toward the gerontological network have the most complex clinical needs.

Regulatory assessment of nano-enabled health products in public health interest. Position of the scientific advisory board of the French National Agency for the Safety of Medicines and Health Products.

Nanomaterials are present in a wide variety of health products, drugs and medical devices and their use is constantly increasing, varying in terms of diversity and quantity. The topic is vast because it covers nanodrugs, but also excipients (that includes varying proportions of NMs) and medical devices (with intended or not-intended (by-products of wear) nanoparticles). Although researchers in the field of nanomedicines in clinical research and industry push for clearer definitions and relevant regulations, the endeavor is challenging due to the enormous diversity of NMs in use and their specific properties. In addition, regulatory hurdles and discrepancies are often cited as obstacles to the clinical development of these innovative products. The scientific council of the Agence Nationale de Sécurité du Médicament et des produits de santé (ANSM) undertook a multidisciplinary analysis encompassing fundamental, environmental and societal dimensions with the aim of identifying topics of interest for regulatory assessment and surveillance. This analysis allowed for proposing some recommendations for approximation and harmonization of international regulatory practices for the assessment of the risk/benefit balance of these products, considering as well the public expectations as regards efficacy and safety of nanomaterials used in Health products, in terms of human and environmental health.

Factors associated with caregivers' underestimation of quality of life in patients with Alzheimer's disease.

OBJECTIVE: The aim of this study was to identify the factors associated with differences between how Alzheimer's disease (AD) patients and their caregivers rate the patient's health-related quality of life (QoL). METHODS: Cross-sectional, multicentre study. Patients were 65 years or more, suffering from mild to moderate AD, native French speakers, with a main caregiver. Interrater agreement of the QoL-AD was assessed using the intraclass coefficient. A generalised linear model was used to identify factors related to the difference in health-related QoL scores between patients and their caregivers. RESULTS: The 122 patients of the study were 82 ± 6 years old and mainly women (69%). Independent factors related to the difference between patients and caregivers were: Mini Mental State Exam score (ß = 0.32; 95% CI = 0.05-0.59); instrumental activities of daily living score (ß = -0.61; 95% CI = -1.14 to -0.07); total Neuropsychiatric Inventory score (ß = 0.10; 95% CI = 0.05-0.59), and Zarit's burden score (ß = 0.09; 95% CI = 0.01-0.17). CONCLUSION: Practitioners must take into account the trend towards underestimation when health-related QoL is rated by caregivers or proxies.

Environmental barriers matter from the early stages of functional decline among older adults in France.

BACKGROUND: The adaptation of living environments can preserve functional independence among older people. A few studies have suggested that this would only benefit the most impaired. But conceptual models theorize that environmental pressure gradually increases with functional decline. OBJECTIVES: We examined (1) how far different environmental barriers increased difficulties and favoured resort to assistance; (2) at what stage in functional decline environmental barriers begin to matter. METHODS: We used the French cross-sectional survey CARE (2015), including 7,451 participants (60+) with at least one severe functional limitation (FL). Multinomial logistic regressions models were used to compare predicted probabilities for outdoor activities of daily living (OADL) difficulties (no OADL difficulties; difficulties but without assistance; use of assistance) among individuals with and without environmental barriers (self-reported or objective), in relation to the number of FLs. RESULTS: Poor-quality pedestrian areas and lack of places to rest were associated with a higher probability of experiencing OADL difficulties, whatever the number of FLs; the association increased with the number of FLs. Up to 6 FLs, individuals with these barriers were more likely to report difficulties without resorting to assistance, with a decreasing association. Living in cities/towns with high diversity of food outlets was associated with a lower probability of reporting assistance, whatever the number of FLs, but with a decreasing association. DISCUSSION: Overall, the results suggest that environmental barriers increasingly contribute to OADL difficulties with the number of FLs. Conclusions differed as to whether they tended to favour resort to assistance, but there was a clear association with food outlets, which decreased with impairment severity. The adaptation of living environments could reduce difficulties in performing activities from the early stages of decline to the most severe impairment. However, the most deteriorated functional impairments seem to generate resort to assistance whatever the quality of the environment.
