Menopause and accelerated aortic stiffness.

BACKGROUND: The menopausal transition is widely believed to increase the risk of cardiovascular disease, based on the notion that estrogen is cardioprotective in women. While aortic stiffness is an independent predictor of cardiovascular disease, it has been unclear whether this risk increases during menopause. OBJECTIVE: This study aimed to determine the association between changes in menopausal status and aortic stiffness. MAIN OUTCOME MEASURES: Menopausal status was classified using the Stages of Reproductive Aging in Women criteria in a stratified random sample of Australian women aged 40-80 years, at three time-points over 14 years (n = 469 in 2001-02 and 2005, and n = 323 in 2014). Aortic stiffness was measured non-invasively via carotid-femoral pulse wave velocity at each time point. Mixed modeling was employed to determine the independent associations between menopausal status and aortic stiffness accounting for multiple covariates including age, systolic blood pressure, heart rate, medications, cholesterol, waist circumference, smoking and diabetes status. RESULTS: There was no evidence to support an association between the menopausal transition and an acceleration of aortic stiffness. However, there was an acceleration of aortic stiffness in the late (8+ years) postmenopause phase, after accounting for age and traditional cardiovascular risk factors (0.122 [95%CI: 0.106, 0.139] m/s/year; p < 0.001). CONCLUSIONS: The menopausal transition is not associated with major changes in aortic stiffness beyond normal age-related effects. However, the clinically significant acceleration in aortic stiffness observed in late postmenopause may contribute to greater cardiovascular risk in this later life phase.

A survey of the Queensland healthcare workforce: attitudes towards dementia care and training.

BACKGROUND: Positive attitudes of healthcare staff towards people with dementia promote higher quality care, although little is known about important factors that underlie positive attitudes. Key aims of this project were to explore the relationships between staff attitudes towards dementia, self-confidence in caring for people with dementia, experience and dementia education and training. METHODS: A brief online survey was developed and widely distributed to registered nurses and allied health professionals working in Queensland in 2012. Regression analyses were performed to identify important predictors of self-confidence in caring for people with dementia and positive attitudes towards people with dementia. RESULTS: Five hundred and twenty-four surveys were completed by respondents working in a range of care settings across Queensland. Respondents were predominantly female (94.1%), and most were registered nurses (60%), aged between 41 and 60 years (65.6%). Around 40% regularly worked with people with dementia and high levels of self-confidence in caring for this population and positive attitudes towards people with dementia were reported. The majority of respondents (67%) had participated in a dementia education/training activity in the past 12 months. More experience working with people with dementia predicted greater self-confidence while recent participation in a dementia education/training and higher self-confidence in caring for a person with dementia significantly predicted more positive attitudes towards people with dementia. CONCLUSIONS: These results confirm the importance of self-confidence and dementia education in fostering positive attitudes and care practices towards people with dementia. Our results also indicate that the demand for ongoing dementia education is high amongst health care workers and it is recommended that regular dementia education/ training be provided and promoted for all healthcare personnel who work with people with dementia.

Development of quality indicators for monitoring outcomes of frail elderly hospitalised in acute care health settings: study protocol.

BACKGROUND: Frail older people admitted to acute care hospitals are at risk of a range of adverse outcomes, including geriatric syndromes, although targeted care strategies can improve health outcomes for these patients. It is therefore important to assess inter-hospital variation in performance in order to plan and resource improvement programs. Clinical quality outcome indicators provide a mechanism for identifying variation in performance over time and between hospitals, however to date there has been no routine use of such indicators in acute care settings. A barrier to using quality indicators is lack of access to routinely collected clinical data. The interRAI Acute Care (AC) assessment system supports comprehensive geriatric assessment of older people within routine daily practice in hospital and includes process and outcome data pertaining to geriatric syndromes. This paper reports the study protocol for the development of aged care quality indicators for acute care hospitals. METHODS/DESIGN: The study will be conducted in three phases: 1. Development of a preliminary inclusive set of quality indicators set based on a literature review and expert panel consultation, 2. A prospective field study including recruitment of 480 patients aged 70 years or older across 9 Australian hospitals. Each patient will be assessed on admission and discharge using the interRAI AC, and will undergo daily monitoring to observe outcomes. Medical records will be independently audited, and 3. Analysis and compilation of a definitive quality indicator set, including two anonymous voting rounds for quality indicator inclusion by the expert panel. DISCUSSION: The approach to quality indicators proposed in this protocol has four distinct advantages over previous efforts: the quality indicators focus on outcomes; they can be collected as part of a routinely applied clinical information and decision support system; the clinical data will be robust and will contribute to better understanding variations in hospital care of older patients; The quality indicators will have international relevance as they will be built on the interRAI assessment instrument, an internationally recognised clinical system.

Dementia risk reduction in primary care: what Australian initiatives can teach us.

Only limited research has been undertaken to identify factors that impede or facilitate the implementation of evidence-based health promotion, prevention and early intervention (PPEI) activities within primary practice. We examined recent Australian initiatives that encouraged primary care practitioners to implement PPEI activities to reduce the risk of chronic disease, particularly those that have focused on lifestyle risk factors. The aim was to identify barriers and facilitators to the uptake of these activities to inform the Australian National Dementia Prevention Strategy. Barriers that were consistently reported across evaluations and that appear to be of most concern to Australian general practitioners include the issues of financial remuneration and time constraints secondary to heavy work commitments. Factors that were effective in overcoming barriers included the integration of interventions within existing activities, the specification of a clear, funded role for practice nurses and the support of the Australian General Practice Network. It was concluded that these factors should be considered if PPEI activities for dementia are to be successfully incorporated within primary care.

The acute-aged care interface: exploring the dynamics of 'bed blocking'.

OBJECTIVE: To understand the dynamics underlying 'bed-blocking' in Australian public hospitals that is frequently blamed on older patients. METHODS: Analysis of primary and secondary data of utilisation patterns of hospital and aged care services by older Australians. RESULTS: A model of the dynamics at the acute-aged care interface was developed, in which the pathway into permanent high-care Residential Aged Care (RAC) is conceptualised as competing queues for available places by applicants from the hospital, the community and from within RAC facilities. The hospital effectively becomes a safety net to accommodate people with high-care needs who cannot be admitted into RAC in a timely manner. CONCLUSION: The model provides a useful tool to explore some of the issues that give rise to access-block within the public hospital system. Access-block cannot be understood by viewing the hospital system in isolation from other sectors that support the health and well-being of older Australians.

Transition care: will it deliver?

Transition care is a new program to Australia that is designed to facilitate transitions of frail older people between the hospital and aged care systems. This program is designed to deliver potentially important improvements to the Australian health care system--but will it deliver? The current evidence base regarding the efficacy of this type of program is mixed, and there is little evidence to indicate improved patient outcomes. An average transition care episode is expensive (about $11 000). Therefore, careful consideration of the relative cost-effectiveness compared with other interface programs such as inpatient subacute services is essential. Transition care services should be established within the context of overall regional plans for aged care, incorporating hospital acute and subacute inpatient services, and long-term community and residential care programs.
