- Abstract
Objectives: To explore the relationship between cognitive performance and falls in older people with mild to moderate cognitive impairment (CI) by investigating the mediational effects of medical, medication, neuropsychological, and physiological factors.Design: Secondary analysis, prospective cohort study.Setting: Community and low-level care.Participants: 177 older people (aged 82 ± 7 years) with mild to moderate CI (MMSE 11-23; ACE-R < 83).Measurements: Global cognition and six neuropsychological domains (memory, language, visuospatial, processing speed, executive function [EF], and affect) were assessed. Participants also underwent sensorimotor and balance assessments. Falls were recorded prospectively for 12 months.Results: The EF domain was most strongly associated with multiple falls (relative risk [RR]: 1.50, 95% CI: 1.18-1.91). Global cognition was not associated with falls (RR: 1.09, 95% CI: 0.92-1.30). Additional analyses showed that participants with poorer EF (median cutpoint) were more likely to be taking centrally acting medications and were less physically active. They also had significantly worse vision, reaction time, knee extension strength, balance (postural sway, controlled leaning balance), and higher physiological fall risk scores. Participants with poorer EF were 1.5 times (RR: 1.50, 95% CI: 1.03-2.18) more likely to have multiple falls. Mediational analyses demonstrated that reaction time and postural sway reduced the relative risk of EF on multiple falls by 31% (RR: 1.19, 95% CI: 0.81-1.74).Conclusions: Within this sample of older people with mild to moderate CI, poorer EF increased the risk of multiple falls. This relationship was mediated by reaction time and postural sway,suggesting cognitively impaired older people with poorer EF may benefit from fall prevention programs targeting these mediating factors.

- Abstract
Background: Persons with dementia (PWD) often have complex medication regimens and are at risk of medication problems during the multiple transitions of care experienced as the condition progresses.Objectives: To explore medication processes in acute care episodes and care transitions for PWD and to make recommendations to improve practice.Method: Semi-structured interviews were conducted by two pharmacy researchers from a focused purposive sample of fifty-one participants (carers, health professionals, Alzheimer's Australia staff) from urban and rural Australia. After written consent, the interviews were audio-recorded then transcribed verbatim for face-to-face interviews, or notes were taken during the interview if conducted by telephone. The transcripts were checked for accuracy by the pharmacy researchers. Thematic analysis of the data was undertaken independently by the two researchers to reduce bias and any disagreements were resolved by discussion.Results: Themes identified were: medication reconciliation; no modified planning for care transitions; underutilization of information technology; multiple prescribers; residential aged care facilities; and medication reviews by pharmacists. Sub themes were: access to appropriate staff; identification of dementia; dose administration aids; and staff training.Conclusions: Medication management is sub-optimal for PWD during care transitions and may compromise safety. Suggested improvements included: increased involvement of pharmacists in care transitions; outreach or transitional health care professionals; modified planning for care transitions for individuals over 80 years; co-ordinated electronic records; structured communication; and staff training.

Objectives: To test different adherent strategies aimed at improving hip protector use among nursing care facility residents. Design, Setting and Participants: A cluster randomized controlled trial with 234 residents older than 75 years from 9 units of 7 nursing care facilities in the Northern Sydney region, Australia. Intervention: Residents were cluster randomized in 3 groups. The first group received hard shell hip protectors without cost (no cost group). The second group received an educational session, a demonstration of the use of hip protectors, and free choice of type of hip protectors without cost (combined group). The third group was the control group who received a brochure about hip protectors. Measurements: Primary outcome was adherence with the use of hip protectors at 3 and 6 months after recruitment. Secondary outcomes were falls, injuries, and fractures. Results: No participants in the control group purchased hip protectors at any stage. At 3 months, 33% of participants in the no cost group and 27% in the combined group wore a hip protector at the time of visit. This declined to 25% and 24% respectively at 6 months. No significant difference was seen in any of the 3 adherence outcomes between the 2 intervention groups. The number of falls or hospitalizations did not differ between groups, with 5 hip fractures reported during the intervention period. Residents were more likely to be adherent if they were female and had greater restriction in daily activities. Conclusion: Providing free hip protectors to older people living in nursing care facilities was necessary to increase initial acceptance and adherence. Nevertheless, after 6 months the achieved level of adherence was not high enough to be associated with a reduction of hip fractures. The provision of educational sessions and demonstrations to nursing staff and participants had no added value in this trial. [Copyright &y& Elsevier]

Objective To compare the costs and cost-effectiveness of a multifactorial interdisciplinary intervention versus usual care for older people who are frail. Design Cost-effectiveness study embedded within a randomized controlled trial. Setting Community-based intervention in Sydney, Australia. Participants A total of 241 community-dwelling people 70 years or older who met the Cardiovascular Health Study criteria for frailty. Intervention A 12-month multifactorial, interdisciplinary intervention targeting identified frailty characteristics versus usual care. Measurements Health and social service use, frailty, and health-related quality of life (EQ-5D) were measured over the 12-month intervention period. The difference between the mean cost per person for 12 months in the intervention and control groups (incremental cost) and the ratio between incremental cost and effectiveness were calculated. Results A total of 216 participants (90%) completed the study. The prevalence of frailty was 14.7% lower in the intervention group compared with the control group at 12 months (95% CI 2.4%–27.0%; P = .02). There was no significant between-group difference in EQ-5D utility scores. The cost for 1 extra person to transition out of frailty was $A15,955 (at 2011 prices). In the “very frail” subgroup (participants met >3 Cardiovascular Health Study frailty criteria), the intervention was both more effective and less costly than the control. A cost-effectiveness acceptability curve shows that the intervention would be cost-effective with 80% certainty if decision makers were willing to pay $A50,000 per extra person transitioning from frailty. In the very frail subpopulation, this reduced to $25,000. Conclusion For frail older people residing in the community, a 12-month multifactorial intervention provided better value for money than usual care, particularly for the very frail, in whom it has a high probability of being cost saving, as well as effective.

RISK factors of falling down , *PHYSICAL activity , *HEALTH of older people , *DEMENTIA , *COGNITION disorders in old age - Abstract
Abstract Background Awareness of physical ability may impact fall risk during everyday tasks. Therefore, we investigated perceived reach (PR; estimation of furthest reach distance), maximal reach (MR) and reach judgement error (RJE), and their relationships with neuropsychological and physical performance, and falls in older people with cognitive impairment (CI). Methods Prospective cohort study of 110 (mean age = 82 ± 7 years; female = 52%) older people with mild-moderate CI (MMSE 11–23; Addenbrooke's Cognitive Examination-Revised (ACE-R) < 83). PR, MR and detailed neuropsychological and physical assessments were assessed at baseline. Participants were divided into tertiles based on their absolute RJE. Falls were recorded prospectively over 12 months with the assistance of carers. Results The populations mean MR was 79 ± 10 cm and PR was 75 ± 13 cm, indicating participants tended to underestimate their reach ability. The large RJE tertile performed significantly poorer in measures of global cognition (ACE-R; OR 0.54 95%CI 0.31–0.95) and executive function (Trail Making Test B; OR 1.84 95%CI 1.00–3.36) and had increased concern about falling (Falls Efficacy Scale-International; OR 2.01 95% CI 1.06–3.79) compared to the minimal RJE tertile. The moderate and large RJE tertile groups had significantly slower hand reaction time and larger postural sway on foam compared to the minimal RJE tertile. Each 1% increase in RJE increased the risk of falls by 2% (RR 1.02 95%CI 1.01–1.03). This relationship withstood adjustment for other fall risk factors (sway on foam, Trail Making Test B and ACE-R). Conclusions Inaccurate reach judgement predicts future falls and is associated with poorer global cognitive performance and executive function, increased concern about falling, slower reaction time and poorer balance. Our results offer insight into the disparity between actual and perceived physical capabilities in people with CI, and how this impacts their risk of falling. Highlights • Judgement error measures the disparity between perceived and actual ability. • Absolute reach judgement error (RJE) predicts falls in cognitively impaired older people. • Larger RJEs were associated with poorer physical and cognitive abilities. • Even so, the RJE-falls relationship was independent of balance, executive and global cognitive function. • RJE may represent a new, complementary, fall risk assessment measure.

Objectives This study aimed to document change in neuropsychological, physical and functional performance over one year and to investigate the relationship between baseline gait speed and cognitive decline in this period in older people with dementia. Methods One hundred and seventy-seven older people with dementia (Mini-Mental State Examination 11–23; Addenbrooke’s Cognitive Examination-Revised <83) residing in the community or low level care facility completed baseline neuropsychological, physical and functional assessments. Of these, 134 participants agreed to reassessment of the above measures one year later. Results Overall, many neuropsychological, physical and functional performance measures declined significantly over the one year study period. Baseline gait speed was significantly associated with decline in verbal fluency (B(109) = 2.893, p = 0.046), specifically phonemic/letter fluency (B(109) = 2.812, p = 0.004) while controlling for age, education, dementia drug use and baseline cognitive performance. There was also a trend for an association between baseline gait speed and decline in clock drawing performance (B(107) = 0.601, p = 0.071). Conclusions Older people with mild to moderate dementia demonstrate significant decline in neuropsychological, physical and functional performance over one year. Baseline gait speed is associated with decline in executive function over one year, suggesting shared pathways/pathology between gait and cognition. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To develop and internally validate a falls prediction tool for people being discharged from inpatient aged care rehabilitation. Study Design and Setting: Prospective cohort study. Possible predictors of falls were collected for 442 aged care rehabilitation inpatients at two hospitals. Results: One hundred fifty participants fell in the 3 months after discharge from rehabilitation (34% of 438 with follow-up data). Predictors of falls were male gender (odds ratio [OR] 2.32, 95% confidence interval [CI]=1.00–4.03), central nervous system medication prescription (OR 2.04, 95% CI=1.00–3.30), and increased postural sway (OR 1.93, 95% CI=1.00–3.26). This three-variable model was adapted for clinical use by unit weighting (i.e., a score of 1 for each predictor present). The area under the receiver operating characteristic curve (AUC) for this tool was 0.69 (95% CI=0.64–0.74, bootstrap-corrected AUC=0.69). There was no evidence of lack of fit between prediction and observation (Hosmer–Lemeshow P =0.158). Conclusion: After external validation, this simple tool could be used to quantify the probability with which an individual will fall in the 3 months after an aged care rehabilitation stay. It may assist in the discharge process by identifying high-risk individuals who may benefit from ongoing assistance or intervention. [Copyright &y& Elsevier]
