What does the general public understand about prevention and treatment of dementia? A systematic review of population-based surveys

Objectives: To synthesise results of population surveys assessing knowledge and attitudes about prevention and treatment of dementia. Methods: MEDLINE, EMBASE, PsycINFO, and grey literature were searched for English language entries published between 2012 and May 2017. Survey questions were grouped using an inductive approach and responses were pooled. Results: Thirty-four eligible studies and four grey literature items were identified. Surveys were conducted in Europe, the US, Eastern Asia, Israel, and Australia. Nearly half of respondents agreed that dementia is a normal and non-preventable part of ageing, but belief in the potential for prevention may be improving over time. The role of cardiovascular risk factors was poorly understood overall. Less than half of respondents reported belief in the availability of a cure for dementia. The value of seeking treatment was highly endorsed. Conclusions: Results suggest that knowledge about the potential for dementia prevention and treatment remains poor but may be improving over time. Knowledge among those living in low- and middle-income countries are largely unknown, presenting challenges for the development of National action plans consistent with World Health Organization directives.Monica Cations, Gorjana Radisic, Maria Crotty, Kate E.

A cross-country comparison of family carers experiences with residential aged care facilities during the COVID-19 pandemic

Background:The number of research projects into residential aged care (RAC) during the COVID-19 pandemic is increasing, however there are limited data on the cross-country comparison of experiences residents living with dementia and their families. Our study aimed to 1) give an overview of the RAC restrictions and changes (visiting policy, governmental & health authorities' advice, service delivery) implemented during the pandemic in Australia, Italy and the UK and 2) and their impact on people with dementia in RAC facilities and their families.Methods:A total of 56 informal family carers of people with dementia residing in RAC took part in semi- structured interviews over the telephone or via Skype in Australia (n=6), Italy (n=25) and the UK (n=26) between July 2020 and March 2021. The interviews were recorded and translated verbatim. Transcripts were analysed by researchers in each country using thematic analysis, then combined across sites.Results:Inductive thematic analysis identified four overarching themes: 1) Adaptations implemented in RAC facilities due to the COVID-19 pandemic in Australia, Italy and the UK; 2) means of communication between RAC facility personnel, people with dementia living in RAC and family members; 3) impact of the implemented restrictions and changes in care provision due to the COVID-19 pandemic on people with dementia in RAC facilities and 4) impact of the implemented restrictions and changes in care provision due to the COVID-19 pandemic on families of people with dementia in RAC facilities. While differences between countries and facilities were identified, the restrictions and changes within the residential care system impacted families' well-being, increased their worries about care quality and safety of people with dementia. The consequences of a lack or modified services for people with dementia included noticeable physical and mental health changes. Although the majority of the facilities implemented some form of video-communication between families and residents, those solutions were unable to replace face-to-face contact.Conclusions:These findings demonstrate the need for implementing safe solutions which might facilitate more frequent in-person contact between families and residents with dementia preventing consequences in mental and physical health in both groups

Costs and economic evaluations of Quality Improvement Collaboratives in healthcare: a systematic review

BACKGROUND:In increasingly constrained healthcare budgets worldwide, efforts to improve quality and reduce costs are vital. Quality Improvement Collaboratives (QICs) are often used in healthcare settings to implement proven clinical interventions within local and national programs. The cost of this method of implementation, however, is cited as a barrier to use. This systematic review aims to identify and describe studies reporting on costs and cost-effectiveness of QICs when used to implement clinical guidelines in healthcare. METHODS:Multiple databases (CINAHL, MEDLINE, PsycINFO, EMBASE, EconLit and ProQuest) were searched for economic evaluations or cost studies of QICs in healthcare. Studies were included if they reported on economic evaluations or costs of QICs. Two authors independently reviewed citations and full text papers. Key characteristics of eligible studies were extracted, and their quality assessed against the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). Evers CHEC-List was used for full economic evaluations. Cost-effectiveness findings were interpreted through the Johanna Briggs Institute 'three by three dominance matrix tool' to guide conclusions. Currencies were converted to United States dollars for 2018 using OECD and World Bank databases. RESULTS:Few studies reported on costs or economic evaluations of QICs despite their use in healthcare. Eight studies across multiple healthcare settings in acute and long-term care, community addiction treatment and chronic disease management were included. Five were considered good quality and favoured the establishment of QICs as cost-effective implementation methods. The cost savings to the healthcare setting identified in these studies outweighed the cost of the collaborative itself. CONCLUSIONS:Potential cost savings to the health care system in both acute and chronic conditions may be possible by applying QICs at scale. However, variations in effectiveness, costs and elements of the method within studies, indicated that caution is needed. Consistent identification of costs and description of the elements applied in QICs would better inform decisions for their use and may reduce perceived barriers. Lack of studies with negative findings may have been due to publication bias. Future research should include economic evaluations with societal perspectives of costs and savings and the cost-effectiveness of elements of QICs.

How, why and under what circumstances does a quality improvement collaborative build knowledge and skills in clinicians working with people with dementia? A realist informed process evaluation

In increasingly constrained health and aged care services, strategies are needed to improve quality and translate evidence into practice. In dementia care, recent failures in quality and safety have led the WHO to prioritise the translation of known evidence into practice. While quality improvement collaboratives have been widely used in healthcare, there are few examples in dementia care. We describe a recent quality improvement collaborative to improve dementia care across Australia and assess the implementation outcomes of acceptability and feasibility of this strategy to translate known evidence into practice. A realist-informed process evaluation was used to analyse how, why and under what circumstances a quality improvement collaborative built knowledge and skills in clinicians working in dementia care. This realist-informed process evaluation developed, tested and refined the programme theory of a quality improvement collaborative. Data were collected pre-intervention and post-intervention using surveys and interviews with participants (n=28). A combined inductive and deductive data analysis process integrated three frameworks to examine the context and mechanisms of knowledge and skill building in participant clinicians. A refined program theory showed how and why clinicians built knowledge and skills in quality improvement in dementia care. Six mechanisms were identified: motivation, accountability, identity, collective learning, credibility and reflective practice. These mechanisms, in combination, operated to overcome constraints, role boundaries and pessimism about improved practice in dementia care. A quality improvement collaborative designed for clinicians in different contexts and roles was acceptable and feasible in building knowledge, skills and confidence of clinicians to improve dementia care. Supportive reflective practice and a credible, flexible and collaborative process optimised quality improvement knowledge and skills in clinicians working with people with dementia.Lenore de la Perrelle, Monica Cations, Gaery Barbery, Gorjana Radisic, Billingsley Kaambwa, Maria Crotty, Janna Anneke Fitzgerald, Susan Kurrle, Ian Cameron, Craig Whitehead, Jane Thompson, Kate Lave

Primary, allied health, geriatric, pain and palliative healthcare service utilisation by aged care residents, 2012-2017.

OnlinePublObjectives To examine the incidence and trends in primary care, allied health, geriatric, pain and palliative care service use by permanent residential aged care (PRAC) residents and the older Australian population. Methods Repeated cross-sectional analyses on PRAC residents (N = 318,484) and the older (≥65 years) Australian population (N ~ 3.5 million). Outcomes were Medicare Benefits Schedule (MBS) subsidised primary care, allied health, geriatric, pain and palliative services between 2012-13 and 2016-17. GEE Poisson models estimated incidence rates and incidence rate ratios (IRR). Results In 2016-17, PRAC residents had a median of 13 (interquartile range [IQR] 5-19) regular general medical practitioner (GP) attendances, 3 (IQR 1-6) after-hours attendances and 5% saw a geriatrician. Highlights of utilisation changes from 2012-13 to 2016-17 include the following: GP attendances increased by 5%/year (IRR = 1.05, 95% confidence interval [CI] 1.05-1.05) for residents compared to 1%/year (IRR = 1.01, 95%CI 1.01-1.01) for the general population. GP after-hours attendances increased by 15%/year (IRR = 1.15, 95%CI 1.14-1.15) for residents and 9%/year (IRR = 1.08, 95%CI 1.07-1.20) for the general population. GP management plans increased by 12%/year (IRR = 1.12, 95%CI 1.11-1.12) for residents and 10%/year (IRR = 1.10, 95%CI 1.09-1.11) for the general population. Geriatrician consultations increased by 28%/year (IRR = 1.28, 95%CI 1.27-1.29) for residents compared to 14%/year (IRR = 1.14, 95%CI 1.14-1.15) in the general population. Conclusions The utilisation of most examined services increased in both cohorts over time. Preventive and management care, by primary care and allied health care providers, was low and likely influences the utilisation of other attendances. PRAC residents' access to pain, palliative and geriatric medicine services is low and may not address the residents' needs.Maria C.

What is the role of modifiable environmental and lifestyle risk factors in young onset dementia?

Young onset dementia (YOD) is associated with significant costs and burden, but its cause is poorly understood. The aim of this review was to determine whether environmental and lifestyle factors are associated with risk for non-autosomal dominant degenerative and vascular YOD. Academic databases were searched to March 2015 for studies assessing the impact of modifiable factors (e.g. education, cardiovascular illness, psychiatric illness, alcohol use) in participants under 65 years at symptom onset. Cardiovascular illness, traumatic brain injury, psychiatric illness, heavy alcohol use and estrogen-related factors were identified as potential risk factors for YOD. Evidence for education, childhood development, smoking and heavy metal exposure was inconsistent or of poor quality. A dose–response relationship was found between cumulative and/or increasing severity of exposure and risk for YOD. Environmental and lifestyle risk factors may be relevant to YOD, particularly with severe or cumulative exposure. More high quality research is required to confirm which factors confer risk and when

Effect of Dementia on Outcomes After Surgically Treated Hip Fracture in Older Adults

Background Hip fractures are associated with increased mortality and functional limitations. However, the effect that dementia has on these outcomes in individuals in aged care settings after fracture is not well established. This study examined the association of dementia with post-hip fracture mortality, permanent residential aged care entry, transition care use, and change in activities of daily living (ADL) needs. Methods A retrospective cohort study using data from the Registry of Senior Australians (2003-2015) was conducted. Individuals with a hip fracture while receiving aged care services were included. Associations of dementia with mortality, risks of transition and permanent care use, and ADL needs progression were estimated using multivariable Cox, Fine-Gray, and logistic regression methods, respectively. Results Of 4771 individuals evaluated, 76% were women, the median age was 86 years (IQR 82-90), and 71% already lived in permanent residential aged care at the time of fracture. Within two years of their hip fracture, 50.4% (95% CI 48.9%-51.8%) of individuals died, 16.2% (95% CI 14.2%-18.2%) entered a transition care program, 59.1% (95% CI 56.5%-61.7%) entered permanent residential aged care, and 32% had greater ADL needs. Dementia was associated with higher risk of two-year mortality (HR = 1.19, 95% CI 1.09-1.30), 90-day entry into permanent care (sHR = 1.96, 95% CI 1.60-2.38), and increased likelihood of ADL limitations (OR = 1.36, 95% CI 1.00-1.85). Minor differences were seen in transition care use by dementia status. Conclusion Dementia is a strong risk factor for mortality after hip fractures in individuals in aged care settings and associated with a high risk of entry into permanent care.Robert N.Jorissen, Maria C.Inacio, Monica Cations, Catherine Lang, Gillian E.Caughey, Maria Crott
