RESUMO
OBJECTIVES: To describe the injury profile, hospitalisation rates and health outcomes for older people with cognitive impairment and to determine whether these differ from those with normal cognition. METHODS: Participants were 867 community-dwelling 70-90 year olds enrolled in the population-based longitudinal Sydney Memory and Ageing Study (MAS). Participant's cognitive status was classified as normal, mild cognitive impairment (MCI) and dementia at baseline, then 2, 4 and 6 years' follow-up. MAS records were linked to hospital and death records to identify injury-related hospitalisations for the 2-year period following each assessment. RESULTS: There were 335 injury-related hospitalisations for participants; 222 (25.6%) participants had at least one injury-related hospitalisation. The injury-related hospitalisation rate for participants with MCI (63.0 [95%CI 51.6-74.4] per 1000 person-years) was higher than for people with normal cognition (39.3 [95%CI 32.4-46.1] per 1000 person-years) but lower than people with dementia (137.1 [95%CI 87.2-186.9] per 1000 person-years). Upper limb fractures (22.1%) were the most common injuries for participants with normal cognition, and non-fracture head injuries for participants with MCI and dementia (25.9% and 23.3% respectively). Participants with dementia had a higher proportion of hip fractures (20.0%, p = 0.0483) than participants with normal cognition. There was no difference in 30-day mortality between participants with normal cognition, MCI and dementia (3.9%, 1.7%, 3.3% respectively). CONCLUSION: Older people with objectively defined MCI are at higher risk of injury-related hospitalisation than their cognitively intact peers, but lower risk than people with dementia. Falls-risk screening and fall prevention initiatives may be indicated for older people with MCI.

BACKGROUND AND PURPOSE: Falls are common in people with Parkinson's disease (PD) but few data exist on fall-related hospitalizations in this group. This population-based study compared fall-related hospital admissions, injury rates and consequences in people with and without PD, and determined whether PD was an independent predictor of fall-related hospital length of stay. METHODS: This was a retrospective study using probabilistic linkage of hospital data in people aged ≥65 years hospitalized for a fall between 1 July 2005 and 31 December 2013 in New South Wales, Australia. Rates of hospital admissions and injuries per person admitted over the study period were compared between people with and without PD using Poisson or negative binomial regression. Multilevel linear modelling was used to analyse length of stay by clustering individuals and adjusting for possible confounders. RESULTS: There were 342 265 fall-related hospital admissions in people aged ≥65 years during the study period, of which 8487 (2.5%) were for people with PD. Sixty-seven per cent of fall-related PD admissions were associated with injury and 35% were associated with fracture. People with PD had higher rate ratios for fall admissions (1.63, 95% confidence interval 1.59-1.67) and injury (1.47, 95% confidence interval 1.43-1.51) and longer median length of stay [9 (interquartile range 1-27) vs. 6 (interquartile range 1-20) days in people without PD; P < 0.001]. PD remained associated with increased length of stay after controlling for comorbidity, age, sex and injury (P < 0.001). CONCLUSIONS: This study provides important benchmark data for hospitalizations for falls and fall injuries for older people with PD, which may be used to monitor the effect of fall prevention programmes.

BACKGROUND: Admission to hospital can lead to persistent deterioration in physical functioning, particularly for the more vulnerable older population. As a result of this physical deterioration, older people who have been recently discharged from hospital may be particularly high users of health and social support services. Quantify usage and costs of services in older adults after hospitalisation and explore the impact of a home-exercise intervention on service usage. METHOD: The present study was a secondary analysis of data from a randomised controlled trial (ACTRN12607000563460). The trial involved 340 participants aged 60 years and over with recent hospitalisation. Service use and costs were compared between intervention (12 months of home-exercise prescribed in 10 visits from a physiotherapist) and control groups. RESULTS: 33 % of participants were re-admitted to hospital, 100 % consulted a General Medical Practitioner and 63 % used social services. 56 % of costs were associated with hospital admission and 22 % with social services. There was reduction in General Medical Practitioner services provided in the home in the intervention group (IRR 0.23, CI 0.1 to 0.545, p < 0.01) but no significant between-group difference in service use or in costs for other service categories. CONCLUSION: There appears to be substantial hospital and social service use and costs in this population of older people. No significant impact of a home-based exercise program was evident on service use or costs. TRIAL REGISTRATION: Australian and New Zealand Clinical Trial Registry ACTRN12607000563460 >TrialSearch.

INTRODUCTION: In order to prevent falls, older people should exercise for at least 2â h per week for 6â months, with a strong focus on balance exercises. This article describes the design of a randomised controlled trial to evaluate the effectiveness of a home-based exercise programme delivered through a tablet computer to prevent falls in older people. METHODS AND ANALYSIS: Participants aged 70â years or older, living in the community in Sydney will be recruited and randomly allocated to an intervention or control group. The intervention consists of a tailored, home-based balance training delivered through a tablet computer. Intervention participants will be asked to complete 2â h of exercises per week for 2â years. Both groups will receive an education programme focused on health-related information relevant to older adults, delivered through the tablet computer via weekly fact sheets. Primary outcome measures include number of fallers and falls rate recorded in weekly fall diaries at 12 months. A sample size of 500 will be necessary to see an effect on falls rate. Secondary outcome measures include concern about falling, depressive symptoms, health-related quality of life and physical activity levels (in all 500 participants); and physiological fall risk, balance, functional mobility, gait, stepping and cognitive performance (in a subsample of 200 participants). Adherence, acceptability, usability and enjoyment will be recorded in intervention group participants over 2 years. Data will be analysed using the intention-to-treat principle. Secondary analyses are planned in people with greater adherence. Economic analyses will be assessed from a health and community care provider perspective. ETHICS AND DISSEMINATION: Ethical approval was obtained from UNSW Ethics Committee in December 2014 (ref number HC#14/266). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conferences. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN)12615000138583.

UNLABELLED: Among 463 community dwellers aged 70-90 years, those with vitamin D insufficiency showed reduced neuromuscular function, balance control and stepping ability and performed worse in tests of cognitive function. In men, vitamin D insufficiency was associated with an increased risk of falling. INTRODUCTION: The purpose of this study was to investigate the relationship between serum 25-hydroxy vitamin D (serum 25OHD) levels, physiological and neuropsychological function in older people, and to examine the relationship between serum 25OHD and prospective falls. METHODS: Four hundred sixty-three community-dwelling people aged 70-90 years underwent an assessment of physiological and neuropsychological performance and structured interviews relating to comorbidity and disability. Fall frequency during the 12 months follow-up was monitored with monthly falls diaries. RESULTS: Twenty-one percent of the men and 44% of the women were vitamin D insufficient (serum 25OHD ≤ 50 nmol/L). Participants with vitamin D insufficiency had weaker upper and lower limb strength, slower simple finger press and choice stepping reaction time, poorer leaning balance and slower gait speed, after controlling for age and body mass index, and, poorer executive function and visuospatial ability, after controlling for age and education. Vitamin D insufficiency significantly increased the rate of falls in men (IRR = 1.94, 95% CI = 1.19-3.15, p = 0.008) but not in women. CONCLUSIONS: These findings highlight the associations between vitamin D insufficiency and impairments in physiological and neuropsychological function that predispose older people to fall. The significant relationship between vitamin D insufficiency and falls found in the men may relate to the stronger association found between serum 25OHD levels and dynamic balance measures evident in this male population.

UNLABELLED: Survival after hospitalisation for hip fracture by age group and sex relative to survival in the general population was assessed in people aged 65+. Men had double the risk of death compared with women to 1 year, but age effects lasted only to 3 months. Clinical outcomes need to be improved. INTRODUCTION: We assessed the relative survival of hospitalised fall-related hip fracture patients aged 65+ years leaving hospital in New South Wales, Australia, between July 2000 and December 2003. METHOD: We carried out a population-based study of all hospital separations for NSW residents with a principal diagnosis of hip fracture (ICD-10-AM S72.0 to S72.2) and first external cause of fall (ICD-10-AM codes W00 to W19), linked to NSW death data. A total of 16,836 cases were included. Relative survival 3 to 36 months post-admission by 10-year age groups and sex was calculated, using NSW life tables for 2002-2004. Relative excess risk was modelled using a generalised linear model with Poisson error structure, using the life table data. RESULTS: One-year cumulative relative survival in 65- to 74-year-olds was 82% (men), 90% (women); in 85+-year-olds 65% (men), 80% (women). Men have a relative excess risk of death of 2.2 (95% CI 2.03-2.38) times that of women. Only 21% of deaths mention the hip fracture as contributing to death. CONCLUSION: There is a need to reduce the number of hip fractures and improve clinical outcomes for older people hospitalised with hip fractures.

The Prevention of Falls Network Europe (ProFaNE) aims to improve quality of life of the ageing population by focussing on a major cause of disability and distress: falls. The thematic network is funded by the European Commission and brings together scientists, clinicians and other health professionals from around Europe to focus on four main themes: taxonomy and coordination of trials, clinical assessment and management of falls, assessment of balance function, and psychological aspects of falling. There are 24 members across Europe as well as network associates who contribute expertise at workshops and meetings. ProFaNE, a 4-year project which started in January 2003, aims to improve and standardise health care processes, introducing and promoting good practice widely across Europe. ProFaNE undertakes workshops that bring together experts and observers around specific topics to exchange knowledge, expertise and resources on interventions that reduce falls. A key document for policy makers around Europe, written by ProFaNE members, was published by the World Health Organisation in March 2004. ProFaNE's website has both public and private areas with resources (web links to falls prevention, useful documents for policy makers, researchers and practitioners) and a discussion board to encourage informal networking between members and the public. The ultimate aim of ProFaNE is to submit a collaborative bid to undertake a multi-centre, randomised controlled trial of a multi-factorial fall prevention intervention with peripheral fracture as the primary outcome. The success of the networking and relationship building in the first year and a half of ProFaNE's work makes this an achievable goal.
RESUMO
We report the case of a 23 year-old female with neurocardiogenic syncope refractory to treatment with other agents who responded to theophylline. Despite inconsistent clinical trial evidence to support its use, theophylline may prove useful in individual cases.

OBJECTIVES: The prevention of falls in the elderly trial (PROFET) provides evidence of the benefits of structured interdisciplinary assessment of older people presenting to the accident and emergency department with a fall. However, the service implications of implementing this effective intervention are significant. This study therefore examined risk factors from PROFET and used these to devise a practical approach to streamlining referrals from accident and emergency departments to specialist falls services. METHODS: Logistic regression analysis was used in the control group to identify patients with an increased risk of falling in the absence of any intervention. The derived predictors were investigated to see whether they also predicted loss to follow up. A second regression analysis was undertaken to test for interaction with intervention. RESULTS: Significant positive predictors of further falls were; history of falls in the previous year (OR 1.5 (95%CI 1.1 to 1.9)), falling indoors (OR 2.4 (95%CI 1.1 to 5.2)), and inability to get up after a fall (OR 5.5 (95%CI 2.3 to 13.0)). Negative predictors were moderate alcohol consumption (OR 0.55 (95%CI 0.28 to 1.1)), a reduced abbreviated mental test score (OR 0.7 (95%CI 0.53 to 0.93)), and admission to hospital as a result of the fall (OR 0.26 (95%CI 0.11 to 0.61)). A history of falls (OR 1.2 (95%CI 1.0 to 1.3)), falling indoors (OR 3.2 (95%CI 1.5 to 6.6)) and a reduced abbreviated mental test score (OR 1.3 (95%CI 1.0 to 1.6)) were found to predict loss to follow up. CONCLUSIONS: The study has focused on a readily identifiable high risk group of people presenting at a key interface between the primary and secondary health care sectors. Analysis of derived predictors offers a practical risk based approach to streamlining referrals that is consistent with an attainable level of service commitment.
