From pilot to a multi-site trial: refining the Early Detection of Deterioration in Elderly Residents (EDDIE +) intervention.

BACKGROUND: Early Detection of Deterioration in Elderly Residents (EDDIE +) is a multi-modal intervention focused on empowering nursing and personal care workers to identify and proactively manage deterioration of residents living in residential aged care (RAC) homes. Building on successful pilot trials conducted between 2014 and 2017, the intervention was refined for implementation in a stepped-wedge cluster randomised trial in 12 RAC homes from March 2021 to May 2022. We report the process used to transition from a small-scale pilot intervention to a multi-site intervention, detailing the intervention to enable future replication. METHODS: The EDDIE + intervention used the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework to guide the intervention development and refinement process. We conducted an environmental scan; multi-level context assessments; convened an intervention working group (IWG) to develop the program logic, conducted a sustainability assessment and deconstructed the intervention components into fixed and adaptable elements; and subsequently refined the intervention for trial. RESULTS: The original EDDIE pilot intervention included four components: nurse and personal care worker education; decision support tools; diagnostic equipment; and facilitation and clinical support. Deconstructing the intervention into core components and what could be flexibly tailored to context was essential for refining the intervention and informing future implementation across multiple sites. Intervention elements considered unsustainable were updated and refined to enable their scalability. Refinements included: an enhanced educational component with a greater focus on personal care workers and interactive learning; decision support tools that were based on updated evidence; equipment that aligned with recipient needs and available organisational support; and updated facilitation model with local and external facilitation. CONCLUSION: By using the i-PARIHS framework in the scale-up process, the EDDIE + intervention was tailored to fit the needs of intended recipients and contexts, enabling flexibility for local adaptation. The process of transitioning from a pilot to larger scale implementation in practice is vastly underreported yet vital for better development and implementation of multi-component interventions across multiple sites. We provide an example using an implementation framework and show it can be advantageous to researchers and health practitioners from pilot stage to refinement, through to larger scale implementation. TRIAL REGISTRATION: The trial was prospectively registered with the Australia New Zealand Clinical Trial Registry (ACTRN12620000507987, registered 23/04/2020).

A stepped-wedge randomised controlled trial assessing the implementation, effectiveness and cost-consequences of the EDDIE+ hospital avoidance program in 12 residential aged care homes: study protocol.

BACKGROUND: Older people living in residential aged care homes experience frequent emergency transfers to hospital. These events are associated with risks of hospital acquired complications and invasive treatments or interventions. Evidence suggests that some hospital transfers may be unnecessary or avoidable. The Early Detection of Deterioration in Elderly residents (EDDIE) program is a multi-component intervention aimed at reducing unnecessary hospital admissions from residential aged care homes by empowering nursing and care staff to detect and manage early signs of resident deterioration. This study aims to implement and evaluate the program in a multi-site randomised study in Queensland, Australia. METHODS: A stepped-wedge randomised controlled trial will be conducted at 12 residential aged care homes over 58 weeks. The program has four components: education and training, decision support tools, diagnostic equipment, and implementation facilitation with clinical systems support. The integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework will be used to guide the program implementation and process evaluation. The primary outcome measure will be the number of hospital bed days used by residents, with secondary outcomes assessing emergency department transfer rates, admission rates, length of stay, family awareness and experience, staff self-efficacy and costs of both implementation and health service use. A process evaluation will assess the extent and fidelity of program implementation, mechanisms of impact and the contextual barriers and enablers. DISCUSSION: The intervention is expected to improve outcomes by reducing unnecessary hospital transfers. Fewer hospital transfers and admissions will release resources for other patients with potentially greater needs. Residential aged care home staff might benefit from feelings of empowerment in their ability to proactively manage early signs of resident deterioration. The process evaluation will be useful for supporting wider implementation of this intervention and other similar initiatives. TRIAL REGISTRATION: The trial is prospectively registered with the Australia New Zealand Clinical Trial Registry ( ACTRN12620000507987 , registered 23/04/2020).

Construction and Validation of the Vestibular Screening Tool for Use in the Emergency Department and Acute Hospital Setting.

OBJECTIVES: To construct a new vestibular screening tool to identify likely vestibular disorders and guide referral of dizzy patients presenting to hospital and to test the vestibular screening tool for construct and discriminative validity and reliability of physiotherapy assessors. DESIGN: Methodologic study. SETTING: Emergency and acute hospital wards of a metropolitan hospital. PARTICIPANTS: Adults (N=114) presenting to hospital with dizziness (mean age, 67.36±14.88y; 57% women). INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Three vestibular screening tools (3, 4, and 5 items) were investigated. Physiotherapy vestibular diagnostic tests categorized patients as vestibular or nonvestibular patients. Subsets of patients were assessed twice by 2 physiotherapists (n=20) and twice by the same physiotherapist (n=30). RESULTS: Each of the vestibular screening tools had a good fit to the Rasch measurement model. Factor analysis demonstrated individual items loaded across 1 factor, confirming unidimensionality of the 3 vestibular screening tools, and Cronbach α determined internal consistency. The 4-item vestibular screening tool had the greatest area under the curve using receiver operator curve analysis (.894), with highest sensitivity (83%) and specificity (84%) for identifying vestibular disorders (cutoff value ≥4/8). Sensitivity of the 3- and 5-item versions was lower than the 4-item vestibular screening tool (80%). The 4-item vestibular screening tool scores showed high intrarater (κ item scores, .831-1; intraclass correlation coefficient [ICC] total, .988) and interrater (κ item scores, .578-.921; ICC total, .878) reliability. CONCLUSIONS: The 4-item vestibular screening tool is a reliable, valid tool for screening dizzy patients presenting to hospital, with unidimensional construct validity, high sensitivity, and specificity for identifying likely vestibular disorders. The vestibular screening tool could be used clinically to streamline referrals of dizzy patients to vestibular clinics.

Breaking the mould without breaking the system: the development and pilot of a clinical dashboard at The Prince Charles Hospital.

There is a vast array of clinical and quality data available within healthcare organisations. The availability of this data in a timely and easy to visualise way is an essential component of high-performing healthcare teams. It is recognised that good quality information is a driver of performance for clinical teams and helps ensure best possible care for patients. In 2012 the Internal Medicine Program at The Prince Charles Hospital developed a clinical dashboard that displays locally relevant information alongside relevant hospital and statewide metrics that inform daily clinical decision making. The data reported on the clinical dashboard is driven from data sourced from the electronic patient journey board in real time as well as other Queensland Health data sources. This provides clinicians with easy access to a wealth of local unit data presented in a simple graphical format that is being captured locally and arranged on a single screen so the information can be monitored at a glance. Local unit data informs daily decisions that identify and confirm patient flow problems, assist to identify root causes and enable evaluation of patient flow solutions.

A qualitative study into the use of formal services for dementia by carers from culturally and linguistically diverse (CALD) communities.

BACKGROUND: People with dementia and their family carers need to be able to access formal services in the community to help maintain their wellbeing and independence. While knowing about and navigating one's way through service systems is difficult for most people, it is particularly difficult for people from culturally and linguistically diverse (CALD) communities. This study addresses a lack of literature on the use of formal services for dementia by people from CALD backgrounds by examining the experiences and perceptions of dementia caregiving within four CALD communities - Italian, Chinese, Spanish and Arabic-speaking - in south western Sydney, Australia. METHODS: The study used a qualitative design and the methods included focus groups with family carers and one-to-one interviews with bilingual/bicultural community workers, bilingual general practitioners and geriatricians. A total of 121 family carers participated in 15 focus groups and interviews were held with 60 health professionals. All fieldwork was audiotaped, transcribed and subjected to thematic analysis. RESULTS: People from CALD communities are often unfamiliar with the concept of formal services and there may be strong cultural norms about maintaining care within the family, rather than relying on external services. CALD communities often have limited knowledge of services. There is a preference for services that will allow families to keep their relative at home, for safety as well as cultural reasons, and they are particularly reluctant to use residential care. While there is a preference for ethno-specific or multicultural services, mainstream services also need to ensure they are more flexible in providing culturally appropriate care. Positive outcomes occur when ethno-specific services work in partnership with mainstream programs. Dementia service providers need to develop a trusting relationship with their local CALD communities and promote their services in a way that is understandable and culturally acceptable to members of these communities. CONCLUSIONS: While members of CALD communities may have difficulties accessing formal services, they will use them if they are culturally and linguistically appropriate and can meet their needs. There are a number of ways to improve service provision to CALD communities and the responsibility for this needs to be shared by a range of stakeholders.

Dementia information for culturally and linguistically diverse communities: sources, access and considerations for effective practice.

Providing information about dementia has been shown to produce immense benefits for people living with dementia and their carers. The dementia information needs of culturally and linguistically diverse (CALD) families have not been comprehensively investigated. Addressing this research gap, the current study examines the perspectives of a range of stakeholders - CALD family caregivers (Arabic, Chinese, Italian and Spanish speaking), bilingual and bicultural workers, bilingual general practitioners and geriatricians - about dementia-related information. The study focussed on sources of information, issues of access and considerations for improving information provision. The main findings that are relevant for improving policy and practice are: the need for a more strategic and coordinated approach to dissemination structures and processes, a greater emphasis on supporting and enhancing the interpersonal aspects of information provision, the need for a greater range of information for CALD communities and the need to ensure information resources and processes reflect the circumstances and needs of these communities.

The relationship between common cognitive screening tests (Standardised Mini-Mental State Examination and Rowland Universal Dementia Assessment Scale) and the Cognitive Functional Independence Measure.

OBJECTIVES: To assess whether the Cognitive Functional Independence Measure (Cog-FIM) is correlated with the Standardised Mini-Mental State Examination (SMMSE) and Rowland Universal Dementia Assessment Scale (RUDAS) and whether there is agreement between the Cog-FIM and these two tests. METHODS: Functional Independence Measure assessments were undertaken on 98 subacute patients. Forty-eight (48) patients were administered the SMMSE, and 50 were administered the RUDAS. Agreement was examined using the Bland-Altman plot. RESULTS: Correlation was observed between the Cog-FIM and both the SMMSE and the RUDAS. The Bland-Altman analysis demonstrated agreement between the Cog-FIM and RUDAS, but not the Cog-FIM and SMMSE. The limits of agreement between the Cog-FIM and RUDAS were -13 to 13. CONCLUSIONS: The Cog-FIM is correlated with the RUDAS, but the agreement is unclear. Despite agreement of the means, the limits of agreement are large, which may suggest a clinically meaningful difference. The study should be repeated with a larger sample size.

Impact of a health services innovation university program in a major public hospital and health service: a mixed methods evaluation.

BACKGROUND: While health services and their clinicians might seek to be innovative, finite budgets, increased demands on health services, and ineffective implementation strategies create challenges to sustaining innovation. These challenges can be addressed by building staff capacity to design cost-effective, evidence-based innovations, and selecting appropriate implementation strategies. A bespoke university award qualification and associated program of activities was developed to build the capacity of staff at Australia's largest health service to implement and evaluate evidence-based practice (EBP): a Graduate Certificate in Health Science majoring in Health Services Innovation. The aim of this study was to establish the health service's pre-program capacity to implement EBP and to identify preliminary changes in capacity that have occurred as a result of the Health Services Innovation program. METHODS: A mixed methods design underpinned by the Consolidated Framework for Implementation Research informed the research design, data collection, and analysis. Data about EBP implementation capacity aligned to the framework constructs were sought through qualitative interviews of university and health service executives, focus groups with students, and a quantitative survey of managers and students. The outcomes measured were knowledge of, attitudes towards, and use of EBP within the health service, as well as changes to practice which students identified had resulted from their participation in the program. RESULTS: The Health Services Innovation program has contributed to short-term changes in health service capacity to implement EBP. Participating students have not only increased their individual skills and knowledge, but also changed their EPB culture and practice which has ignited and sustained health service innovations and improvements in the first 18 months of the program. Capacity changes observed across wider sections of the organization include an increase in connections and networks, use of a shared language, and use of robust implementation science methods such as stakeholder analyses. CONCLUSION: This is a unique study that assessed data from all stakeholders: university and health service executives, students, and their managers. By assembling multiple perspectives, we identified that developing the social capital of the organization through delivering a full suite of capacity-building initiatives was critical to the preliminary success of the program.

Development of a questionnaire to assess clinician perspectives of the usefulness of the Functional Independence Measure (FIM) and cognitive screening tests.

OBJECTIVE: A pilot questionnaire was developed to investigate the cognitive tests that clinicians employ in their clinical practice and whether they perceive the Functional Independence Measure (FIM) to add clinical value. METHODS: A 10-item pilot questionnaire was created and distributed to 43 health professionals of a single health service in Australia. A snowballing approach to sampling was used. RESULTS: There were 39 respondents. Less than half of respondents thought the FIM added clinical value, and 15% stated that they would use the FIM to assess cognition on subacute wards. Ninety-seven per cent (97%) of respondents stated that they would rely more heavily on cognitive screening tests than the FIM. CONCLUSION: Participant responses to this survey of a single health service raise interesting questions about how useful clinicians perceive the FIM to be, beyond a costing and benchmarking role. Clinicians may prefer cognitive screening tests to the FIM, in clinical practice.

The validity of the Rowland Universal Dementia Assessment Scale (RUDAS) in a multicultural cohort of community-dwelling older persons with early dementia.

The 6-item Rowland Universal Dementia Assessment Scale (RUDAS) is a simple, portable multicultural scale for detecting dementia. Items address executive function, praxis, gnosis, recent memory, and category fluency. It can be directly translated to other languages, without the need to change the structure or the format of any item. The RUDAS was administered to 151 consecutive, consenting, culturally diverse community-dwelling subjects of mean age 77 years, 72% of whom had an informant. Subjects were recruited from various clinics and healthcare programs. All were evaluated for cognitive impairment in a blinded manner by experienced clinicians in geriatric medicine. According to Diagnostic and Statistical Manual of Mental Disorder-IV criteria, 40% of the subjects were normal, 22% had cognitive impairment (not otherwise specified), and 38% had dementia; 84% of whom had questionable or mild dementia. In the primary analysis (normal subjects vs. those with definite dementia), the RUDAS accurately identified dementia, with an area under the receiver operating characteristic curve of 0.94 (95% confidence interval, 0.88-0.97); at the published cut point of less than 23/30, the positive likelihood ratio (LR) for dementia diagnosis was 8.77, and the negative likelihood ratio was 0.14. Additional analyses showed that the RUDAS performed less well when subjects with cognitive impairment (not dementia) were included. In all logistic regression models, the RUDAS was an independent predictor of dementia (odds ratio 0.64, 95% confidence interval, 0.52-0.79, primary analysis model), after adjusting for age, sex, years of education, and cultural diversity, none of which were independent predictors. Further studies are needed across the full spectrum of early dementia syndromes, and in additional ethnic minority groups.

Standardised assessment of older patients by a nurse in an emergency department.

The primary aim of this study was to evaluate the ability of a nurse practitioner in geriatrics, working in the emergency department of a tertiary referral hospital, to assess high-risk elderly patients comprehensively. A secondary aim was to explore patient characteristics associated with referral to community aged care services. Of 469 patients assessed by the nurse, 327 (70%) were admitted to the hospital. A comprehensive set of data was obtained for 334 (71%) patients. For 142 patients not admitted, 163 new referrals were made, mostly to the Aged Care Assessment Team. Those referred were more likely to be living alone and non-English speaking. They were also less satisfied with the support they received from family and friends. A single nurse working in a busy emergency department can successfully identify patients with increased care needs, and direct high-risk patients to existing services.

The role of the bilingual/bicultural worker in dementia education, support and care.

Members of minority populations often have difficulty knowing about and accessing dementia services. One of the strategies used to promote access is the employment of bilingual/bicultural workers (sometimes referred to as multicultural, link or outreach workers). This study involved interviews with 24 bilingual/bicultural workers in south western Sydney, Australia to gain a better understanding of their role within the dementia field. Seven themes emerged: importance of working with family; process of building trust when moving between two cultures; importance of understanding the culture; self-care and culture; flexibility of their role; linking community members; and linking communities to mainstream services. Bilingual/bicultural workers play a significant and complex role in supporting individuals and families within their community who are affected by dementia. The significance of their role needs to be more clearly acknowledged in the development of policy, further research and service provision within the dementia field.

The Rowland Universal Dementia Assessment Scale (RUDAS) and the Folstein MMSE in a multicultural cohort of elderly persons.

OBJECTIVE: To compare the accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) and the Folstein Mini-mental State Examination (MMSE) for diagnosis of dementia in a multicultural cohort of elderly persons. METHODS: A total of 129 community-dwelling persons were selected at random from a database of referrals to an aged-care team. Subjects were stratified according to language background and cognitive diagnosis, and matched for age and gender. The RUDAS and the MMSE were administered to each subject in random order. Within several days, a geriatrician assessed each subject for dementia (DSM-IV criteria) and disease severity (Clinical Dementia Rating Scale). All assessments were carried out independent and blind. The geriatrician also administered the Modified Barthel Index and the Lawton Instrumental Activities of Daily Living Scale, and screened all participants for non-cognitive disorders that might affect instrument scores. RESULTS: The area under the receiver operating characteristic curve (AUC) for the RUDAS [0.92, 95% confidence interval (95%CI) 0.85-0.96] was similar to the AUC for the MMSE (0.91, 95%CI 0.84-0.95). At the published cut-points (RUDAS < 23/30, MMSE < 25/30), the positive and negative likelihood ratios for the RUDAS were 19.4 and 0.2, and for the MMSE 2.1 and 0.14, respectively. The MMSE, but not the RUDAS, scores were influenced by preferred language (p = 0.015), total years of education (p = 0.016) and gender (p = 0.044). CONCLUSIONS: The RUDAS is at least as accurate as the MMSE, and does not appear to be influenced by language, education or gender. The high positive likelihood ratio for the RUDAS makes it particularly useful for ruling-in disease.

Accuracy of the clock drawing test for detecting dementia in a multicultural sample of elderly Australian patients.

OBJECTIVE: To assess the accuracy of clock drawing for detecting dementia in a multicultural, non-English-speaking-background population. DESIGN: A prospective cohort study. SETTING: A general geriatric medical outpatient clinic in southwest Sydney, Australia. PARTICIPANTS: Ninety-three consecutive new patients to the clinic who had a non-English-speaking-background country of birth (mean age 78.0 years). MEASUREMENTS: The clock drawing test was conducted at the beginning of each clinic visit by a blinded investigator. Each patient was then assessed by a geriatrician who collected demographic data, administered the Modified Barthel Index, the Geriatric Depression Scale, and the Folstein Mini-Mental State Examination, and categorized each patient as normal or demented, according to DSM-IV criteria. Interpreters were used for participants who spoke a language other than English or who requested them. Each clock drawing was scored according to the 4-point CERAD scale and the previously published methods of Mendez, Shulman, Sunderland, Watson, and Wolf-Klein. Scoring was evaluated for reliability and predictive accuracy, using receiver operating characteristic (ROC) curve analysis. Logistic regression analysis was used to assess the potential interaction between level of education and each of the clock scoring methods. RESULTS: Using ROC curve analysis, there was no significant difference between the clock scoring methods (area under the curve varied from 0.60 to 0.72). The most sensitive was the Mendez scoring method (98%), with a specificity of 16%. Specificity above 50% was found only for the Wolf-Klein method, with an intermediate sensitivity of 78%. CONCLUSIONS: There were no significant differences in the clock scoring methods used to detect dementia. Performance of the clock drawing test was modest at best with low levels of specificity across all methods. Scored according to these methods, clock drawing was not a useful predictor of dementia in our multicultural population.

The Rowland Universal Dementia Assessment Scale (RUDAS): a multicultural cognitive assessment scale.

OBJECTIVE: To develop and validate a simple method for detecting dementia that is valid across cultures, portable and easily administered by primary health care clinicians. DESIGN: Culture and Health Advisory Groups were used in Stage 1 to develop culturally fair cognitive items. In Stage 2, clinical testing of 42 items was conducted in a multicultural sample of consecutive new referrals to the geriatric medicine outpatient clinic at Liverpool Hospital, Sydney, Australia (n = 166). In Stage 3, the predictive accuracy of items was assessed in a random sample of community-dwelling elderly persons stratified by language background and cognitive diagnosis and matched for sex and age (n = 90). MEASUREMENTS: A research psychologist administered all cognitive items, using interpreters when needed. Each patient was comprehensively assessed by one of three geriatricians, who ordered relevant investigations, and implemented a standardized assessment of cognitive domains. The geriatricians also collected demographic information, and administered other functional and cognitive measures. DSM-IV criteria were used to assign cognitive diagnoses. Item validity and weights were assessed using frequency and logistic regression analyses. Receiver-operating characteristic (ROC) curve analysis was used to determine overall predictive accuracy of the RUDAS and the best cut-point for detecting cognitive impairment. RESULTS: The 6-item RUDAS assesses multiple cognitive domains including memory, praxis, language, judgement, drawing and body orientation. It appears not to be affected by gender, years of education, differential performance factors and preferred language. The area under the ROC curve for the RUDAS was 0.94 (95% CI 0.87-0.98). At a cut-point of 23 (maximum score of 30), sensitivity and specificity were 89% and 98%, respectively. Inter-rater (0.99) and test-retest (0.98) reliabilities were very high. CONCLUSIONS: The 6-item RUDAS is portable and tests multiple cognitive domains. It is easily interpreted to other languages, and appears to be culturally fair. However, further validation is needed in other settings, and in longitudinal studies to determine its sensitivity to change in cognitive function over time.
