Prof Jacqui Close is a consultant in Orthogeriatrics at the Prince of Wales Hospital in Sydney and Clinical Director of the Falls, Balance and Injury Research Centre at Neuroscience Research Australia. Her primary research area is falls in people with cognitive impairment and dementia and particularly the relationship of cognitive function to postural stability, falls and fractures. She also has an epidemiological interest in the impact of falls and injury to health service use and the way in which health services are designed to prevent and manage falls and injury in older people. She sits on a number of State and National committees in relation to Aged Health and is Co-Chair of the ANZ Hip Fracture Registry, Chair of the ACSQHC Clinical Care Standards Working Group for Hip Fracture and the President of the Australian and New Zealand Society of Geriatric Medicine.

CURRENT PROJECTS

Care of Older People in Surgery

Each year the number of older people undergoing surgery increases. Although evidence is well established that older age and frailty are associated with greater risk of poorer postoperative outcomes, there is little evidence to date to establish whether outcomes can be improved through geriatric intervention.

Care of Older People in Surgery

Preventing further falls in people who call an ambulance as a result of a fall – a randomised contro

Many older people suffer a fall and it is not uncommon for older fallers to require paramedic care following such events. Routine transportation to hospital is of questionable value and may not be an effective or efficient use of resources. This randomised controlled offered non-transported fallers a new model of care following fall-related paramedic care.

Patterns of use and cost to the ambulance service of fall-related injury in older people

While the pattern of ambulance use have been studied extensively, the associated costs which are influenced by a variety of factors are still being explored. This program of research aims to better understand what is driving costs within the ambulance service, explore pathways to optimise resource use and evaluate models of care to streamline health care provided to older adults.

Evaluation and comparison of comorbidity measures to predict mortality and morbidity in older popula

This program of research evaluates the performance of commonly used comorbidity measures (Charlson Comorbidity Index, Elixhauser and Multipurpose Australian Comorbidity Scoring System) on the prediction of 30-day and 1-year mortality, 28 day re-admission, and length of stay in an older hip fracture population.

Causes, consequences and costs of injury-related hospitalisations for people with dementia: identify

This research program explores the influence of dementia on the pattern of hospital admissions, clinical care, health outcomes and economic costs of older people with an injury-related hospitalisation. It provides data on the impact of injury on a person with dementia and the health system more generally.

Determinants of uptake of home modifications and exercise to prevent falls in community-dwelling old

This research examines the age-specific population prevalence and predictors of uptake of home modifications and exercise to prevent falls in the older population in NSW.

Preventing Falls in Older Adults with Cognitive Impairement or Dementia (IFOCIS)

The IFOCIS study aims to determine the ability of an individualised exercise and home hazard reduction program to reduce the rates of falls in older people living in the community with cognitive impairment or dementia. To do this, we have two groups– an ‘intervention’ group and a ‘control’ group. The Intervention program involves: an exercise program and a home hazard reduction program delivered by experienced therapists tailored to the participant’s cognitive and physical abilities. Carers are an integral part of the intervention team, as some participants require supervision for exercise sessions. We work with carers to help them understand how to get the best from the participant they are caring for, in terms of their ‘functional cognition’, completing the exercises and preventing falls.

Taking this individual approach means that participants can have very different cognitive abilities and still be included in our study. No other study has done this to date.

All participants will undergo an assessment at baseline with re tests at 6 and 12 months to compare each of these groups on things like strength & balance. The primary outcome is the rate of falls during the 12 month study period which is collected using falls diaries on a monthly basis.

Recruitment for the project is now in the 2nd year. We have enrolled 184 participants and their carers into the trial from the Prince of Wales hospital / NeuRA site and the Hornsby hospital site. We hope to have 360 participants enrolled by the end of 2017. We continue to recruit from Prince of Wales and Hornsby hospital wards and outpatient clinics and other Sydney metropolitan hospital dementia day clinics.

Understanding and preventing physical and cognitive decline and falls in older people with dementia

Falls and functional decline are common in people with dementia. Falls are more likely to result in injury, death and institutionalisation when compared to older people without dementia. There is limited evidence that falls can be prevented in people with dementia. Strategies aimed at maintaining independence and preventing decline and falls are urgently needed. This research will a) further our understanding of fall risk and functional decline and b) explore novel fall and decline prevention programs, including the use of technology in older people with dementia.

Australian and New Zealand Hip Fracture Registry (ANZHFR)

There are approximately 17,000 new hip fractures in Australia and 4,000 in New Zealand annually. The cost of the event is enormous, both for the individual and their family, as well as the health care system. There is variation in models of hip fracture care within and between States and Territories (Aus) and District Health Boards (NZ). Much of what happens in the acute and rehabilitation settings impacts directly on the longer term outcomes for the person with the fracture. The ANZHFR allows for timely comparison of meaningful data that can be used by providers of care to understand clinical practice, and trigger a case for change in places where improvement can be made.

Exercise for falls prevention in Parkinson disease: a randomized controlled trial.

Canning CG, Sherrington C, Lord SR, Close JC, Heritier S, Heller GZ, Howard K, Allen NE, Latt MD, Murray SM, O'Rourke SD, Paul SS, Song J, Fung VS

To determine whether falls can be prevented with minimally supervised exercise targeting potentially remediable fall risk factors, i.e., poor balance, reduced leg muscle strength, and freezing of gait, in people with Parkinson disease. An exercise program targeting balance, leg strength, and freezing of gait did not reduce falls but improved physical and psychological health. Falls were reduced in people with milder disease but not in those with more severe Parkinson disease.

The association of physical illness and self-harm resulting in hospitalisation among older people in a population-based study.

Mitchell R, Draper B, Harvey L, Brodaty H, Close J

With population ageing, self-harm injuries among older people are increasing. Further examination of the association of physical illness and self-harm among older people is warranted. This research aims to identify the association of physical illness with hospitalisations following self-harm compared to non-self-harm injury among older people. Older people who are experiencing chronic health conditions, particularly tinnitus, malignancies, diabetes and chronic pain may be at risk of self-harm. Targeted screening may assist in identifying older people at risk of self-harm.
