RESUMO

PURPOSE: This systematic review aimed to update fragility hip fracture incidences in the Asia Pacific, and compare rates between countries/regions. METHOD: A systematic search was conducted in four electronic databases. Studies reporting data between 2010 and 2023 on the geographical incidences of hip fractures in individuals aged ≥50 were included. Exclusion criteria were studies reporting solely on high-trauma, atypical, or periprosthetic fractures. We calculated the crude incidence, age- and sex-standardised incidence, and the female-to-male ratio. The systematic review was registered with PROSPERO (CRD42020162518). RESULTS: Thirty-eight studies were included across nine countries/regions (out of 41 countries/regions). The crude hip fracture incidence ranged from 89 to 341 per 100,000 people aged ≥50, with the highest observed in Australia, Taiwan, and Japan. Age- and sex-standardised rates ranged between 90 and 318 per 100,000 population and were highest in Korea and Japan. Temporal decreases in standardised rates were observed in Korea, China, and Japan. The female-to-male ratio was highest in Japan and lowest in China. CONCLUSION: Fragility hip fracture incidence varied substantially within the Asia-Pacific region. This observation may reflect actual incidence differences or stem from varying research methods and healthcare recording systems. Future research should use consistent measurement approaches to enhance international comparisons and service planning.

RESUMO

Background This report provides the theory, method and practice of culturally secure translation and knowledge exchange in the Healing Right Way Clinical Trial (2017-2022), outlining activities to date. Healing Right Way was a stepped wedge cluster randomised controlled trial conducted in Western Australia, aimed at enhancing rehabilitation services and quality of life for Aboriginal Australians following acquired brain injury. The trial translation plan was aspirational and action-oriented, with its implementation iterative and ongoing. Translational activities aimed to inform service and research planning for Aboriginal people with brain injury. Situated in the intercultural space, the work guards against undertaking activities that are monocultural, colonial and appropriating in favour of work that is authentically viewed through the dual lens of whiteness and Aboriginal and Torres Strait Islander ways of knowing, being and doing, and is strengths-based. Methods Three translational and knowledge exchange components were identified, relating to the role of Aboriginal Brain Injury Coordinators, cultural training of hospital staff and the research process itself. Knowledge plans were developed for key audiences, with potential translation products to be monitored for ongoing impact. Results Results demonstrate that translational and knowledge exchange were iteratively embedded throughout the trial life cycle. Data sources included community engagement, partnership meetings and interviews. Activities involved presentations to diverse audiences including bureaucrats, community and participants. Conclusions This report provides a snapshot of the first translation knowledge exchange plan and activities constructed in relation to brain injury rehabilitation services for Aboriginal people. Challenges encountered, as well as successes to date, are discussed.

RESUMO

Preventing avoidable venous-thrombo-embolism (VTE) is a priority to improve patient and service outcomes after total hip and total knee arthroplasty (THA, TKA), but compliance with relevant clinical guidelines varies. This study aims to determine the degree to which prophylaxis was compliant with Australian Orthopaedic Association (AOA) VTE prophylaxis guidelines and whether non-compliance is associated with increased risk of VTE. A prospective multi-centre cohort study of adults with osteoarthritis undergoing primary TKA/THA was completed at 19 high-volume public and private hospitals. Data were collected prior to surgery and for one-year post-surgery. Logistic regression was undertaken to explore associations between non-compliance with AOA VTE prophylaxis guidelines and symptomatic 90-day VTE outcomes. Data were analysed for 1838 participants from 19 sites. The rate of non-compliance with all clinical guideline recommendations was 20.1% (N = 369), with 14.1% (N = 259) non-compliance for risk-stratified prophylaxis, 35.8% (N = 658) for duration, and 67.8% (N = 1246) for other general recommendations. Symptomatic VTE was experienced up to 90-days post-surgery by 48 people (2.6%). Overall guideline non-compliance (AOR = 0.93, 95%CI = 0.4 to 1.3, p = 0.86) was not associated with a lower risk of symptomatic 90-day VTE. Results were consistent when people with high bleeding risk were excluded (AOR = 0.94, 95%CI = 0.44 to 2.34, p = 0.89). Non-compliance with the AOA VTE prophylaxis guidelines was not associated with risk of 90-day VTE after arthroplasty. This counterintuitive finding is concerning and necessitates a rigorous review of the AOA VTE prevention clinical guideline.

RESUMO

OBJECTIVE: The aim of this study was to examine temporal trends (2016-2020) in hip fracture care in Australian and New Zealand (ANZ) hospitals that started providing patient-level data to the ANZ Hip Fracture Registry (ANZHFR) on/before 1 January 2016 (early contributors). METHODS: Retrospective cohort study of early contributor hospitals (n = 24) to the ANZHFR. The study cohort included patients aged ≥50 years admitted with a low trauma hip fracture between 1 January 2016 and 31 December 2020 (n = 26,937). Annual performance against 11 quality indicators and 30- and 365-day mortality were examined. RESULTS: Compared to 2016/2017, year-on-year improvements were demonstrated for preoperative cognitive assessment (2020: OR 3.57, 95% confidence interval [95% CI] 3.29-3.87) and nerve block use prior to surgery (2020: OR 4.62, 95% CI 4.17-5.11). Less consistent improvements over time from 2016/2017 were demonstrated for emergency department (ED) stay of <4 h (2017; 2020), pain assessment ≤30 min of ED presentation (2020), surgery ≤48 h (2020) and bone protection medication prescribed on discharge (2017-2020; 2020 OR 2.22, 95% CI 2.03-2.42). The odds of sustaining a hospital-acquired pressure injury increased in 2019-2020 compared to 2016. The odds of receiving an orthogeriatric model of care and being offered the opportunity to mobilise on Day 1 following surgery fluctuated. There was a reduction in 365-day mortality in 2020 compared to 2016 (OR 0.86, 95% CI 0.74-0.98), whereas 30-day mortality did not change. CONCLUSIONS: Several quality indicators improved over time in early contributor hospitals. Indicators that did not improve may be targets for future care improvement activities, including considering incentivised hip fracture care, which has previously been shown to improve care/outcomes. COVID-19 and reporting practices may have impacted the study findings.

RESUMO

BACKGROUND: In addition to providing patient care, interprofessional health care teams work collaboratively on a variety of projects. These projects often benefit from using facilitated small group project discussion sessions, such as the Harvard Macy Institute's (HMI) Step Back Process (SBP). Although having a trained facilitator is an important component of the SBP, only a limited number of health care professionals can attend HMI courses in person or virtually, limiting its impact. APPROACH: We developed three video-based education (VBE) modules to deliver facilitator training on the SBP, informed by principles of Mayer's cognitive theory of multimedia learning. For module development, we used a five-step approach. We evaluated effectiveness of the modules as a self-directed method to enhance SBP facilitator training. An initial survey collected demographic data and module feedback, a follow-up survey collected feedback on the modules' impact on facilitation and interviews focused on the participants' overall experience. EVALUATION: Survey results indicated that the modules were positively received and helped to improve participant confidence in facilitating. We identified four themes from the interviews: challenges of facilitating, value of group feedback, value of modules for experienced facilitators and the modules as part of a multi-modal approach to train new facilitators. IMPLICATIONS: This innovation provides insight on delivering facilitator training on the SBP using VBE. Health professions educators developing online facilitator training could adapt our development process and modify implementation guided by our results. Future work should evaluate the best methods to integrate VBE modules into a longitudinal virtual community and assess facilitation techniques.

RESUMO

In this article, we explore the benefits of recognizing the impact of intersectionality on access to, and provision of, brain injury care in a First Nations context. While disadvantage and discrimination are often associated with the intersection of culture, gender, disability, and socioeconomic disadvantage, it is only when these factors are explored together that clinicians can really understand what people need to recover and thrive following acquired brain injury. In this article, we challenge speech-language pathologists to examine their own practices, to look beyond Western models of health and constraints of many current institutional models of care and ways of framing research, to acknowledge historical and ongoing colonizing influences, and to engage with community-led solutions. We provide a model of Aboriginal-led care, where intersection of discrimination and marginalization is minimized and the multiple components of the individual, carers/communication partners, and the environment become empowering factors instead.

RESUMO

In this series of eight articles, the Australian Traumatic Brain Injury Initiative (AUS-TBI) consortium describes the Australian approach used to select the common data elements collected acutely that have been shown to predict outcome following moderate-severe traumatic brain injury (TBI) across the lifespan. This article presents the unified single data dictionary, together with additional measures chosen to facilitate comparative effectiveness research and data linkage. Consultations with the AUS-TBI Lived Experience Expert Group provided insights on the merits and considerations regarding data elements for some of the study areas, as well as more general principles to guide the collection of data and the selection of meaningful measures. These are presented as a series of guiding principles and themes. The AUS-TBI Aboriginal and Torres Strait Islander Advisory Group identified a number of key points and considerations for the project approach specific to Aboriginal and Torres Strait Islander peoples, including key issues of data sovereignty and community involvement. These are outlined in the form of principles to guide selection of appropriate methodologies, data management, and governance. Implementation of the AUS-TBI approach aims to maximize ongoing data collection and linkage, to facilitate personalization of care and improved outcomes for people who experience moderate-severe TBI.

RESUMO

BACKGROUND: Peroral endoscopic myotomy (POEM) is a relatively new but increasingly therapeutic option for achalasia. In recent years, POEM has been used for nonachalasia esophageal motility disorders (NAEMDs), such as diffuse esophageal spasm, esophagogastric junction outlet obstruction, and hypercontractile disorder, with some clinical success. No studies thus far compare the outcomes of these two groups. We perform the first head-to-head comparison of outcomes after POEM in patients with achalasia and NAEMD. PATIENTS AND METHODS: A retrospective analysis of all patients undergoing POEM at one university hospital by a single expert endoscopist from July 2021 to December 2022 was performed. All patients were symptomatic, and the presence of esophageal motility disorders was confirmed using multiple diagnostic modalities. These patients were then divided into 2 groups, achalasia and NAEMD, based on the underlying diagnosis. Statistical analysis of different clinical outcomes, including effectiveness and safety, was performed. RESULTS: Thirty-seven patients (mean age: 59.55, females: 22) underwent POEM in the study period. Twenty patients had achalasia and 17 patients had NAEMD. The median myotomy length was 5.5 cm for the achalasia group and 10 cm for the NAEMD group. This excluded patients with esophagogastric junction outlet obstruction in which the median myotomy length was 3 cm. The procedure time, the duration of hospital stays, the rates of same-day discharge, and complications were similar between the two. Short-term outcomes of POEM for the two groups were similar with improvement in 94% of patients in the achalasia group and 93.75% in the NAEMD group. CONCLUSION: Contrary to prior observations, our study highlights that POEM is equally effective in achieving clinical improvement in patients with NAEMD as achalasia over 6 months of follow-up. In addition, POEM has a comparable safety profile in both patient groups making it a feasible therapeutic option for these debilitating and challenging disorders.

RESUMO

BACKGROUND: A hip fracture in an older person is a devastating injury. It impacts functional mobility, independence and survival. Models of care may provide a means for delivering integrated hip fracture care in less well-resourced settings. The aim of this review was to determine the elements of hip fracture models of care to inform the development of an adaptable model of care for low and middle-income countries (LMICs). METHODS: Multiple databases were searched for papers reporting a hip fracture model of care for any part of the patient pathway from injury to rehabilitation. Results were limited to publications from 2000. Titles, abstracts and full texts were screened based on eligibility criteria. Papers were evaluated with an equity lens against eight conceptual criteria adapted from an existing description of a model of care. RESULTS: 82 papers were included, half of which were published since 2015. Only two papers were from middle-income countries and only two papers were evaluated as reporting all conceptual criteria from the existing description. The most identified criterion was an evidence-informed intervention and the least identified was the inclusion of patient stakeholders. CONCLUSION: Interventions described as models of care for hip fracture are unlikely to include previously described conceptual criteria. They are most likely to be orthogeriatric approaches to service delivery, which is a barrier to their implementation in resource-limited settings. In LMICs, the provision of orthogeriatric competencies by other team members is an area for further investigation.

RESUMO

Campus sexual misconduct policies (SMPs) outline prohibited conduct. We sought to document the range of terms used to refer to forms of nonconsensual sexual contact in SMPs and to analyze the content of definitions provided for the term "sexual assault." We coded the 2016-2017 SMPs from a sample of 381 U.S. schools. We identified 125 unique terms and documented both a terminological and conceptual morass around sexual assault. Policy language may have implications for students' and administrators' evaluation of experiences and reports of sexual assault.

RESUMO

PURPOSE: Colonisation and continuing discrimination have significantly and negatively impacted the physical, social and emotional wellbeing of First Nations peoples globally. In Australia, Aboriginal cultures thrive despite ongoing barriers to health care. This paper describes challenges and new initiatives for Australian Aboriginal people with acquired communication disability after brain injury and their alignment with the global aims forming the Sustainable Development Goals. RESULT: Research undertaken by an Aboriginal and non-Aboriginal multidisciplinary team over a decade in Western Australia identified and responded to mismatches between community needs and services. Initiatives described include the Missing Voices, Healing Right Way, Brain Injury Yarning Circles and Wangi/Yarning Together projects. Recommendations implemented related to (a) greater incorporation of Aboriginal cultural protocols and values within services, (b) more culturally secure assessment and treatment tools, (c) support after hospital discharge, (d) Aboriginal health worker involvement in support. Implementation includes cultural training of hospital staff, trialling new assessment and treatment methods, and establishing community-based Aboriginal Brain Injury Coordinator positions and relevant peer support groups. CONCLUSION: Culturally secure brain injury rehabilitation in Australia is in its infancy. Our initiatives challenge assumptions about worldviews and established Western biomedical models of healthcare through incorporating Indigenous methodologies and leadership, and community-driven service delivery. This commentary paper focuses on Sustainable Development Goals 3, 16 and 17.

RESUMO

BACKGROUND: Aboriginal Australians are known to suffer high levels of acquired brain injury (stroke and traumatic brain injury) yet experience significant barriers in accessing rehabilitation services. The aim of the Healing Right Way trial is to evaluate a culturally secure intervention for Aboriginal people with newly acquired brain injury to improve their rehabilitation experience and quality of life. Following publication of the trial protocol, this paper outlines the statistical analysis plan prior to locking the database.  METHODS: The trial involves a stepped wedge design with four steps over 3 years. Participants were 108 adult Aboriginal Australians admitted to one of eight hospitals (four rural, four urban) in Western Australia within 6 weeks of onset of a new stroke or traumatic brain injury who consented to follow-up for 26 weeks. All hospital sites started in a control phase, with the intervention assigned to pairs of sites (one metropolitan, one rural) every 26 weeks until all sites received the intervention. The two-component intervention involves training in culturally safe care for hospital sites and enhanced support provided to participants by Aboriginal Brain Injury Coordinators during their hospital stay and after discharge. The primary outcome is quality of life as measured by the Euro QOL-5D-3L VAS. A mixed effects linear regression model will be used to assess the between-group difference at 26 weeks post-injury. The model will control for injury type and severity, age at recruitment and time since commencement of the trial, as fixed effects. Recruitment site and participant will be included as random effects. Secondary outcomes include measurements of function, independence, anxiety and depression, carer strain, allied health occasions of service received and hospital compliance with minimum processes of care based on clinical guidelines and best practice models of care. DISCUSSION: The trial will provide the first data surrounding the effectiveness of an intervention package for Aboriginal people with brain injury and inform future planning of rehabilitation services for this population. The statistical analysis plan outlines the analyses to be undertaken. TRIAL REGISTRATION: Australia New Zealand Clinical Trials Registry ACTRN12618000139279. Registered 30 January, 2018.

RESUMO

BACKGROUND: Surgical site infection (SSI) and venous thromboembolism (VTE) are associated with high burden and cost and are considered largely preventable following total knee or hip arthroplasty (TKA, THA). The risk of developing VTE and SSI is reduced when prophylaxis is compliant with evidence-based clinical guidelines. However, the association between VTE and antibiotic prophylaxis clinical guideline compliance and patient-reported outcome measures (PROMs) after THA/TKA is unknown. This study aims to explore whether care that is non-compliant with VTE and antibiotic guideline recommendations is associated with PROMs (Oxford Hip/Knee Score and EQ-5D Index scores) at 90- and 365-days after surgery. METHODS: This prospective observational study included high-volume arthroplasty public and private sites and consenting eligible participants undergoing elective primary THA/TKA. We conducted multiple linear regression and linear mixed-effects modelling to explore the associations between non-compliance with VTE and antibiotic guidelines, and PROMs. RESULTS: The sample included 1838 participants. Compliance with VTE and antibiotic guidelines was 35% and 13.2% respectively. In adjusted modelling, non-compliance with VTE guidelines was not associated with 90-day Oxford score (ß = - 0.54, standard error [SE] = 0.34, p = 0.112) but was significantly associated with lower (worse) 365-day Oxford score (ß = - 0.76, SE = 0.29, p = 0.009), lower EQ-5D Index scores at 90- (ß = - 0.02 SE = 0.008, p = 0.011) and 365-days (ß = - 0.03, SE = 0.008, p = 0.002).. The changes in Oxford and EQ-5D Index scores were not clinically important. Noncompliance with antibiotic guidelines was not associated with either PROM at 90- (Oxford: ß = - 0.45, standard error [SE] = 0.47, p = 0.341; EQ-5D: ß = - 0.001, SE = 0.011, p = 0.891) or 365-days (Oxford score: ß = - 0.06, SE = 0.41, p = 0.880 EQ-5D: ß = - 0.010, SE = 0.012, p = 0.383). Results were consistent when complications were included in the model and in linear mixed-effects modelling with the insurance sector as a random effect. CONCLUSIONS: Non-compliance with VTE prophylaxis guidelines, but not antibiotic guidelines, is associated with statistically significant but not clinically meaningful differences in Oxford scores and EQ-5D Index scores at 365 days.

RESUMO

This narrative review describes efforts to improve the care and prevention of fragility fractures in New Zealand from 2012 to 2022. This includes development of clinical standards and registries to benchmark provision of care, and public awareness campaigns to promote a life-course approach to bone health. PURPOSE: This review describes the development and implementation of a systematic approach to care and prevention for New Zealanders with fragility fractures, and those at high risk of first fracture. Progression of existing initiatives and introduction of new initiatives are proposed for the period 2022 to 2030. METHODS: In 2012, Osteoporosis New Zealand developed and published a strategy with objectives relating to people who sustain hip and other fragility fractures, those at high risk of first fragility fracture or falls and all older people. The strategy also advocated formation of a national fragility fracture alliance to expedite change. RESULTS: In 2017, a previously informal national alliance was formalised under the Live Stronger for Longer programme, which includes stakeholder organisations from relevant sectors, including government, healthcare professionals, charities and the health system. Outputs of this alliance include development of Australian and New Zealand clinical guidelines, clinical standards and quality indicators and a bi-national registry that underpins efforts to improve hip fracture care. All 22 hospitals in New Zealand that operate on hip fracture patients currently submit data to the registry. An analogous approach is ongoing to improve secondary fracture prevention for people who sustain fragility fractures at other sites through nationwide access to Fracture Liaison Services. CONCLUSION: Widespread participation in national registries is enabling benchmarking against clinical standards as a means to improve the care of hip and other fragility fractures in New Zealand. An ongoing quality improvement programme is focused on eliminating unwarranted variation in delivery of secondary fracture prevention.

RESUMO

In reduced-order modeling, complex systems that exhibit high state-space dimensionality are described and evolved using a small number of parameters. These parameters can be obtained in a data-driven way, where a high-dimensional dataset is projected onto a lower-dimensional basis. A complex system is then restricted to states on a low-dimensional manifold where it can be efficiently modeled. While this approach brings computational benefits, obtaining a good quality of the manifold topology becomes a crucial aspect when models, such as nonlinear regression, are built on top of the manifold. Here, we present a quantitative metric for characterizing manifold topologies. Our metric pays attention to non-uniqueness and spatial gradients in physical quantities of interest, and can be applied to manifolds of arbitrary dimensionality. Using the metric as a cost function in optimization algorithms, we show that optimized low-dimensional projections can be found. We delineate a few applications of the cost function to datasets representing argon plasma, reacting flows and atmospheric pollutant dispersion. We demonstrate how the cost function can assess various dimensionality reduction and manifold learning techniques as well as data preprocessing strategies in their capacity to yield quality low-dimensional projections. We show that improved manifold topologies can facilitate building nonlinear regression models.

RESUMO

Objective: People with type 2 diabetes are likely to experience shame or guilt as they navigate through their disease. Previous research has shown that feelings of shame and guilt often exist within the clinician-patient relationship, often as a result of the complex care regimen required to achieve treatment goals. The purpose of this qualitative study was to explore patients' experiences of shame and guilt in type 2 diabetes management and the impact their clinicians have on these experiences. Methods: Semistructured interviews were used to explore patients' experiences with shame and guilt. Interviews were audio-recorded, transcribed, and coded using directed content analysis. Demographic data were also obtained. Results: We completed 20 interviews with people with type 2 diabetes (65% Black, 70% female). Participants exhibited feelings more consistent with guilt than with shame. All participants discussed how their clinicians affected these feelings. Patients who expressed feelings of guilt were able to recognize opportunities for behavior change without experiencing global devaluation, in which they linked their actions to an unchangeable aspect of their identity or personality, often describing their guilt as motivating of change. Unlike guilt, when patients experienced shame, they often exhibited global devaluation, in which they blamed their personality, experienced hopelessness, and increased maladaptive behaviors. Conclusion: Our findings highlight a notable difference between shame and guilt in the context of type 2 diabetes management. We believe that incorporation of an understanding of these nuances, along with ideal responses to both shame and guilt, will enhance clinicians' ability to provide high-quality patient-centered care to people with diabetes.

RESUMO

Globally, populations are ageing and the estimated number of hip fractures will increase from 1.7 million in 1990 to more than 6 million in 2050. The greatest increase in hip fractures is predicted in Low- and Middle-Income Countries (LMICs), largely in the Asia-Pacific region where direct costs are expected to exceed $US15 billion by 2050. The aims of this qualitative study are to identify barriers to, and enablers of, evidence-informed hip fracture care in LMICs, and to determine if the Blue Book standards, developed by the British Orthopaedic Association and British Geriatrics Society to facilitate evidence-informed care of patients with fragility fractures, are applicable to these settings. This study utilized semi-structured interviews with clinical and administrative hospital staff to explore current hip fracture care in LMICs. Transcribed interviews were imported into NVivo 12 and analysed thematically. Interviews were conducted with 35 participants from 11 hospitals in 5 countries. We identified five themes-costs of care and the capacity of patients to pay, timely hospital presentation, competing demands on limited resources, delegation and defined responsibility and utilization of available data-and within each theme, barriers and enablers were distinguished. We found a mismatch between patient needs and provision of recommended hip fracture care, which in LMICs must commence at the time of injury. This study describes clinician and administrator perspectives of the barriers to, and enablers of, high-quality hip fracture care in LMICs; results indicate that initiatives to overcome barriers (in particular, delays to definitive treatment) are required. While the Blue Book offers a starting point for clinicians and administrators looking to provide high-quality hip fracture care to older people in LMICs, locally developed interventions are likely to provide the most successful solutions to improving hip fracture care.

RESUMO

BACKGROUND: Treatment fidelity is inconsistently reported in aphasia research, contributing to uncertainty about the effectiveness of types of aphasia therapy following stroke. We outline the processes and outcomes of treatment fidelity monitoring in a pre-specified secondary analysis of the VERSE trial. METHODS: VERSE was a 3-arm, single-blinded RCT with a 12-week primary endpoint comparing Usual Care (UC) to two higher intensity treatments: Usual Care-Plus (UC-Plus) and VERSE, a prescribed intervention. Primary outcome results were previously reported. This secondary analysis focused on treatment fidelity. Video-recorded treatment sessions in the higher intensity study arms were evaluated for treatment adherence and treatment differentiation. Treatment components were evaluated using a pre-determined fidelity checklist. PRIMARY OUTCOME: prescribed amount of therapy time (minutes); secondary outcomes: (i) adherence to therapy protocol (%) and (ii) treatment differentiation between control and high intensity groups. RESULTS: Two hundred forty-six participants were randomised to Usual Care (n=81), Usual Care-Plus (n=82), and VERSE (n=83). One hundred thirty-five (82%) participants in higher intensity intervention arms received the minimum prescribed therapy minutes. From 10,805 (UC 7787; UC-Plus 1450; VERSE 1568) service events, 431 treatment protocol deviations were noted in 114 participants. Four hundred thirty-seven videos were evaluated. The VERSE therapists achieved over 84% adherence to key protocol elements. Higher stroke and aphasia severity, older age, and being in the UC-Plus group predicted more treatment deviations. CONCLUSIONS: We found high levels of treatment adherence and differentiation between the intervention arms, providing greater confidence interpreting our results. The comprehensive systems for intervention fidelity monitoring and reporting in this trial make an important contribution to aphasia research and, we argue, should set a new standard for future aphasia studies.

RESUMO

PURPOSE: Multilingual children are disproportionately represented on speech pathology caseloads, in part due to the limited ability of traditional language assessments to accurately capture multilingual children's language abilities. This systematic review evaluates the evidence for identification of language disorder in multilingual children using dynamic assessment and considers clinical applications of the evidence. METHOD: A systematic search of the Cumulative Index to Nursing and Allied Health Literature, Education Resources Information Centre, Education Source, Google Scholar, Linguistics, Medline, and PsycINFO databases produced 10 articles that met the inclusion criteria: between-groups comparison studies that used dynamic assessment to identify language disorder in children under 12 years old that spoke a different language at home to the majority society language. Articles were critically appraised using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) protocol. RESULTS: Nine of the 10 studies reported that their dynamic assessment identified language disorder in multilingual children. However, small sample sizes, limited language pairs, variability in the reference standard, and design deficiencies resulted in poor ratings for all studies on QUADAS-2. CONCLUSIONS: The studies in this review reflected an emergent area of research. Preliminary guidelines for clinical application indicate that dynamic assessment may be a suitable and time-efficient complementary method of diagnosis of language disorder in multilingual children. Further recommendations about age of use, language of instruction, and relevant scores are included.

RESUMO

OBJECTIVES: Develop and implement a Communication Enhanced Environment model and explore its effect on language activities for patients early after stroke. METHOD AND DESIGN: Before-and-after pilot study. SETTING: An acute/slow stream rehabilitation and a rehabilitation ward in a private hospital in Perth, Western Australia. PARTICIPANTS: Fourteen patients recruited within 21 days of stroke. Seven recruited during the before-phase (control group: patients with aphasia = 3, patients without aphasia = 4) and seven recruited in the after-phase (intervention group: patients with aphasia = 4, patients without aphasia = 3). INTERVENTION: The intervention group exposed to a Communication Enhanced Environment model had access to equipment, resources, planned social activities and trained communication partners. Both groups received usual stroke care. DATA COLLECTION: Hospital site champions monitored the availability of the intervention. Behavioural mapping completed during the first minute of each 5-minute interval over 12 hours (between 7 am and 7 pm) determined patient engagement in language activities. RESULTS: Seventy-one percent of the Communication Enhanced Environment model was available to the intervention group who engaged in higher, but not significant (95% CI), levels of language activities (600 of 816 observation time points, 73%) than the control group (551 of 835 observation time points, 66%). Unforeseen reorganisation of the acute ward occurred during the study. CONCLUSIONS: Implementation of a Communication Enhanced Environment model was feasible in this specific setting and may potentially influence patients' engagement in language activities. The unforeseen contextual challenges that occurred during the study period demonstrate the challenging nature of the hospital environment and will be useful in future research planning.
