The Diet Quality of Australian Stroke Survivors in a Community Setting.

INTRODUCTION: Diet quality is a marker of how closely eating patterns reflect dietary guidelines. The highest tertile for diet quality scores is associated with 40% lower odds of first stroke compared with the lowest tertile. Little is known about the diet of stroke survivors. We aimed to assess dietary intake and quality of Australian stroke survivors. METHODS: Stroke survivors enrolled in the ENAbLE pilot trial (2019/ETH11533, ACTRN12620000189921) and Food Choices after Stroke study (2020ETH/02264) completed the Australian Eating Survey Food Frequency Questionnaire (AES), a 120-item, semiquantitative questionnaire of habitual food intake over the previous 3-6 months. Diet quality was determined by calculating the Australian Recommended Food Score (ARFS): a higher score indicates higher diet quality. RESULTS: Eighty-nine adult, stroke survivors (female: n = 45, 51%) of mean age 59.5 years (±9.9) had a mean ARFS of 30.5 (±9.9) (low diet quality). Mean energy intake was similar to the Australian population: 34.1% from noncore (energy-dense/nutrient-poor) and 65.9% from core (healthy) foods. However, participants in the lowest tertile for diet quality (n = 31) had significantly lower intake of core (60.0%) and higher intake from noncore foods (40.0%). Most participants did not meet daily requirements for fiber, potassium, or omega 3 fatty acids (2%, 15%, and 18%), nutrients important to reduce stroke risk. CONCLUSION: The diet quality of stroke survivors was poor, with inadequate intake of nutrients important for reducing recurrent stroke risk. Further research is needed to develop effective interventions to improve diet quality.

Establishing Quality Indicators and Implementation Priorities for Post-Stroke Aphasia Services Through End-User Involvement.

BACKGROUND: Currently, there are no agreed quality standards for post-stroke aphasia services. Therefore, it is unknown if care reflects best practices or meets the expectations of people living with aphasia. We aimed to (1) shortlist, (2) operationalise and (3) prioritise best practice recommendations for post-stroke aphasia care. METHODS: Three phases of research were conducted. In Phase 1, recommendations with strong evidence and/or known to be important to people with lived experience of aphasia were identified. People with lived experience and health professionals rated the importance of each recommendation through a two-round e-Delphi exercise. Recommendations were then ranked for importance and feasibility and analysed using a graph theory-based voting system. In Phase 2, shortlisted recommendations from Phase 1 were converted into quality indicators for appraisal and voting in consensus meetings. In Phase 3, priorities for implementation were established by people with lived experience and health professionals following discussion and anonymous voting. FINDINGS: In Phase 1, 23 best practice recommendations were identified and rated by people with lived experience (n = 26) and health professionals (n = 81). Ten recommendations were shortlisted. In Phase 2, people with lived experience (n = 4) and health professionals (n = 17) reached a consensus on 11 quality indicators, relating to assessment (n = 2), information provision (n = 3), communication partner training (n = 3), goal setting (n = 1), person and family-centred care (n = 1) and provision of treatment (n = 1). In Phase 3, people with lived experience (n = 5) and health professionals (n = 7) identified three implementation priorities: assessment of aphasia, provision of aphasia-friendly information and provision of therapy. INTERPRETATION: Our 11 quality indicators and 3 implementation priorities are the first step to enabling systematic, efficient and person-centred measurement and quality improvement in post-stroke aphasia services. Quality indicators will be embedded in routine data collection systems, and strategies will be developed to address implementation priorities. PATIENT AND PUBLIC CONTRIBUTION: Protocol development was informed by our previous research, which explored the perspectives of 23 people living with aphasia about best practice aphasia services. Individuals with lived experience of aphasia participated as expert panel members in our three consensus meetings. We received support from consumer advisory networks associated with the Centre for Research Excellence in Aphasia Rehabilitation and Recovery and the Queensland Aphasia Research Centre.

Delivering COVID-19 Vaccine via Trusted Social Services: Program Evaluation Results from the Chicagoland CEAL Program.

To describe the reach, implementation, and sustainability of COVID-19 vaccination programs delivered by social service community organizations. Five academic institutions in the Chicagoland CEAL (Community Engagement Alliance) program partnered with 17 community organizations from September 2021-April 2022. Interviews, community organizations program implementation tracking documents, and health department vaccination data were used to conduct the evaluation. A total of 269 events were held and 5,432 COVID-19 vaccines delivered from May 2021-April 2022. Strategies that worked best included offering vaccinations in community settings with flexible and reliable hours; pairing vaccinations with ongoing social services; giving community organizations flexibility to adjust programs; offering incentives; and vaccinating staff first. These strategies and partnership structures supported vaccine uptake, community organization alignment with their missions and communities' needs, and trust. Community organizations delivering social services are local community experts and trusted messengers. Pairing social service delivery with COVID-19 vaccination built individual and community agency. Giving COs creative control over program implementation enhanced trust and vaccine delivery. When given appropriate resources and control, community organizations can quickly deliver urgently needed health services in a public health crisis.

Adapting a Telehealth Physical Activity and Diet Intervention to a Co-Designed Website for Self-Management After Stroke: Tutorial.

People who experience a stroke are at a higher risk of recurrent stroke when compared with people who have not had a stroke. Addressing modifiable risk factors like physical inactivity and poor diet has been shown to improve blood pressure, a leading contributor to stroke. However, survivors of stroke often experience challenges with accessing risk reduction services including long wait lists, difficulty with transportation, fatigue, impaired function, and diminished exercise capacity. Providing health interventions via a website can extend the reach when compared with programs that are only offered face to face or via real-time telehealth. Given global challenges of accessing secondary prevention programs, it is important to consider alternative ways that this information can be made available to survivors of stroke worldwide. Using the "design thinking" framework and drawing on principles of the integrated knowledge translation approach, we adapted 2 co-designed telehealth programs called i-REBOUND - Let's get moving (physical activity intervention) and i-REBOUND - Eat for health (diet Intervention) to create the i-REBOUND after stroke website. The aim of this paper is to describe the systematic process undertaken to adapt resources from the telehealth delivered i-REBOUND - Let's get moving and i-REBOUND - Eat for health programs to a website prototype with a focus on navigation requirements and accessibility for survivors of stroke. We engaged a variety of key stakeholders with diverse skills and expertise in areas of stroke recovery, research, and digital health. We established a governance structure, formed a consumer advisory group, appointed a diverse project team, and agreed on scope of the project. Our process of adaptation had the following 3 phases: (1) understand, (2) explore, (3) materialize. Our approach considered the survivor of stroke at the center of all decisions, which helped establish guiding principles related to our prototype design. Careful and iterative engagement with survivors of stroke together with the application of design thinking principles allowed us to establish the functional requirements for our website prototype. Through user testing, we were able to confirm the technical requirements needed to build an accessible and easy-to-navigate website catering to the unique needs of survivors of stroke. We describe the process of adapting existing content and co-creating new digital content in partnership with, and featuring, people who have lived experience of stroke. In this paper, we provide a road map for the steps taken to adapt resources from 2 telehealth-delivered programs to a website format that meets specific navigation and accessibility needs of survivors of stroke.

Paleoecology provides context for conserving culturally and ecologically important pine forest and barrens communities.

In fire-prone ecosystems, knowledge of vegetation-fire-climate relationships and the history of fire suppression and Indigenous cultural burning can inform discussions of how to use fire as a management tool, particularly as climate continues to change rapidly. On Wiisaakodewan-minis/Stockton Island in the Apostle Islands National Lakeshore of Wisconsin, USA, structural changes in a pine-dominated natural area containing a globally rare barrens community occurred after the cessation of cultural burning by the Indigenous Ojibwe people and the imposition of fire-suppression policies, leading to questions about the historical role of fire in this culturally and ecologically important area. To help understand better the ecological context needed to steward these pine forest and barrens communities, we developed palaeoecological records of vegetation, fire, and hydrological change using pollen, charcoal, and testate amoebae preserved in peat and sediment cores collected from bog and lagoon sediments within the pine-dominated landscape. Results indicated that fire has been an integral part of Stockton Island ecology for at least 6000 years. Logging in the early 1900s led to persistent changes in island vegetation, and post-logging fires of the 1920s and 1930s were anomalous in the context of the past millennium, likely reflecting more severe and/or extensive burning than in the past. Before that, the composition and structure of pine forest and barrens had changed little, perhaps due to regular low-severity surface fires, which may have occurred with a frequency consistent with Indigenous oral histories (~4-8 years). Higher severity fire episodes, indicated by large charcoal peaks above background levels in the records, occurred predominantly during droughts, suggesting that more frequent or more intense droughts in the future may increase fire frequency and severity. The persistence of pine forest and barrens vegetation through past periods of climatic change indicates considerable ecological resistance and resilience. Future persistence in the face of climate changes outside this historical range of variability may depend in part on returning fire to these systems.

Development of a burst wave lithotripsy system for noninvasive fragmentation of ureteroliths in pet cats.

BACKGROUND: Upper urinary tract stones are increasingly prevalent in pet cats and are difficult to manage. Surgical procedures to address obstructing ureteroliths have short- and long-term complications, and medical therapies (e.g., fluid diuresis and smooth muscle relaxants) are infrequently effective. Burst wave lithotripsy is a non-invasive, ultrasound-guided, handheld focused ultrasound technology to disintegrate urinary stones, which is now undergoing human clinical trials in awake unanesthetized subjects. RESULTS: In this study, we designed and performed in vitro testing of a modified burst wave lithotripsy system to noninvasively fragment stones in cats. The design accounted for differences in anatomic scale, acoustic window, skin-to-stone depth, and stone size. Prototypes were fabricated and tested in a benchtop model using 35 natural calcium oxalate monohydrate stones from cats. In an initial experiment, burst wave lithotripsy was performed using peak ultrasound pressures of 7.3 (n = 10), 8.0 (n = 5), or 8.9 MPa (n = 10) for up to 30 min. Fourteen of 25 stones fragmented to < 1 mm within the 30 min. In a second experiment, burst wave lithotripsy was performed using a second transducer and peak ultrasound pressure of 8.0 MPa (n = 10) for up to 50 min. In the second experiment, 9 of 10 stones fragmented to < 1 mm within the 50 min. Across both experiments, an average of 73-97% of stone mass could be reduced to fragments < 1 mm. A third experiment found negligible injury with in vivo exposure of kidneys and ureters in a porcine animal model. CONCLUSIONS: These data support further evaluation of burst wave lithotripsy as a noninvasive intervention for obstructing ureteroliths in cats.

Interventions for the uptake of evidence-based recommendations in acute stroke settings.

BACKGROUND: There is a growing body of research evidence to guide acute stroke care. Receiving care in a stroke unit improves access to recommended evidence-based therapies and patient outcomes. However, even in stroke units, evidence-based recommendations are inconsistently delivered by healthcare workers to patients with stroke. Implementation interventions are strategies designed to improve the delivery of evidence-based care. OBJECTIVES: To assess the effects of implementation interventions (compared to no intervention or another implementation intervention) on adherence to evidence-based recommendations by health professionals working in acute stroke units. Secondary objectives were to assess factors that may modify the effect of these interventions, and to determine if single or multifaceted strategies are more effective in increasing adherence with evidence-based recommendations. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, Joanna Briggs Institute and ProQuest databases to 13 April 2022. We searched the grey literature and trial registries and reviewed reference lists of all included studies, relevant systematic reviews and primary studies; contacted corresponding authors of relevant studies and conducted forward citation searching of the included studies. There were no restrictions on language and publication date. SELECTION CRITERIA: We included randomised trials and cluster-randomised trials. Participants were health professionals providing care to patients in acute stroke units; implementation interventions (i.e. strategies to improve delivery of evidence-based care) were compared to no intervention or another implementation intervention. We included studies only if they reported on our primary outcome which was quality of care, as measured by adherence to evidence-based recommendations, in order to address the review aim. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies for inclusion, extracted data and assessed risk of bias and certainty of evidence using GRADE. We compared single implementation interventions to no intervention, multifaceted implementation interventions to no intervention, multifaceted implementation interventions compared to single implementation interventions and multifaceted implementation interventions to another multifaceted intervention. Our primary outcome was adherence to evidence-based recommendations. MAIN RESULTS: We included seven cluster-randomised trials with 42,489 patient participants from 129 hospitals, conducted in Australia, the UK, China, and the Netherlands. Health professional participants (numbers not specified) included nursing, medical and allied health professionals. Interventions in all studies included implementation strategies targeting healthcare workers; three studies included delivery arrangements, no studies used financial arrangements or governance arrangements. Five trials compared a multifaceted implementation intervention to no intervention, two trials compared one multifaceted implementation intervention to another multifaceted implementation intervention. No included studies compared a single implementation intervention to no intervention or to a multifaceted implementation intervention. Quality of care outcomes (proportions of patients receiving evidence-based care) were included in all included studies. All studies had low risks of selection bias and reporting bias, but high risk of performance bias. Three studies had high risks of bias from non-blinding of outcome assessors or due to analyses used. We are uncertain whether a multifaceted implementation intervention leads to any change in adherence to evidence-based recommendations compared with no intervention (risk ratio (RR) 1.73; 95% confidence interval (CI) 0.83 to 3.61; 4 trials; 76 clusters; 2144 participants, I2 =92%, very low-certainty evidence). Looking at two specific processes of care, multifaceted implementation interventions compared to no intervention probably lead to little or no difference in the proportion of patients with ischaemic stroke who received thrombolysis (RR 1.14, 95% CI 0.94 to 1.37, 2 trials; 32 clusters; 1228 participants, moderate-certainty evidence), but probably do increase the proportion of patients who receive a swallow screen within 24 hours of admission (RR 6.76, 95% CI 4.44 to 10.76; 1 trial; 19 clusters; 1,804 participants; moderate-certainty evidence). Multifaceted implementation interventions probably make little or no difference in reducing the risk of death, disability or dependency compared to no intervention (RR 0.93, 95% CI 0.85 to 1.02; 3 trials; 51 clusters ; 1228 participants; moderate-certainty evidence), and probably make little or no difference to hospital length of stay compared with no intervention (difference in absolute change 1.5 days; 95% CI -0.5 to 3.5; 1 trial; 19 clusters; 1804 participants; moderate-certainty evidence). We do not know if a multifaceted implementation intervention compared to no intervention result in changes to resource use or health professionals' knowledge because no included studies collected these outcomes. AUTHORS' CONCLUSIONS: We are uncertain whether a multifaceted implementation intervention compared to no intervention improves adherence to evidence-based recommendations in acute stroke settings, because the certainty of evidence is very low.

Codesigning implementation strategies to improve evidence-based stroke rehabilitation: A feasibility study.

INTRODUCTION: People with lived experience are rarely involved in implementation science research. This study was designed to assess the feasibility of codesigning and delivering implementation strategies with people with lived experience of stroke and health professionals to improve evidence-based stroke rehabilitation. METHODS: We used Experience-Based CoDesign to design and deliver strategies to implement Stroke Clinical Guideline recommendations at one Australian inpatient stroke rehabilitation unit. Workgroups were formed with health professionals and people with 6-12 months experience of living with stroke (survivors and carers). Feasibility of the codesign approach (focusing on acceptability, implementation fidelity, signal of promise) was evaluated using mixed methods, using data from interviews, observations and inpatient self-reported outcomes. RESULTS: Of 18 people with stroke invited, eight (44%) agreed to join the lived experience workgroup. All disciplines with ≥1 full-time staff members on the stroke unit were represented on the health professional workgroup. Median workgroup attendance over 6 months was n = 8 health professionals, n = 4 survivors of stroke and n = 1 carers. Workgroup members agreed to focus on two Guideline recommendations: information provision and amount of therapy. Workgroup members indicated that the codesign approach was enjoyable and facilitated effective partnerships between health professionals and lived experience workgroup members. Both cohorts reported contributing valuable input to all stages of the project, with responsibility shifting between groups at different project stages. The codesigned strategies signalled promise for improving aspects of information provision and creating additional opportunities for therapy. We could not compare patient-reported outcomes before and after the implementation period due to high variability between the preimplementation and postimplementation patient cohorts. CONCLUSION: It is feasible to codesign implementation strategies in inpatient rehabilitation with people with lived experience of stroke and health professionals. More research is required to determine the effect of the codesigned strategies on patient and service outcomes. PATIENT OR PUBLIC CONTRIBUTION: People with lived experience of stroke codesigned and evaluated implementation strategies. Author F. C. has lived experience of stroke and being an inpatient at the inpatient rehabilitation service, and has provided input into analysis of the findings and preparation of this manuscript.

Prospective application of theoretical implementation frameworks to improve health care in hospitals - a systematic review.

BACKGROUND: Health Service implementation projects are often guided by theoretical implementation frameworks. Little is known about the effectiveness of these frameworks to facilitate change in processes of care and patient outcomes within the inpatient setting. The aim of this review was to assess the effectiveness of the application of theoretical implementation frameworks in inpatient healthcare settings to change processes of care and associated patient outcomes. METHOD: We conducted a search in CINAHL, MEDLINE, EMBASE, PsycINFO, EMCARE and Cochrane Library databases from 1st January 1995 to 15th June 2021. Two reviewers independently applied inclusion and exclusion criteria to potentially eligible studies. Eligible studies: implemented evidence-based care into an in-patient setting using a theoretical implementation framework applied prospectively; used a prospective study design; presented process of care or patient outcomes; and were published in English. We extracted theoretical implementation frameworks and study design against the Workgroup for Intervention Development and Evaluation Research (WIDER) Checklist and implementation strategies mapped to the Cochrane Effective Practice and Organisation of Care (EPOC) taxonomy. We summarised all interventions using the Template for Intervention Description and Replication (TIDieR) checklist. We appraised study quality using the Item bank on risk of bias and precision of observational studies and the revised Cochrane risk of bias tool for cluster randomised trials. We extracted process of care and patient outcomes and described descriptively. We conducted meta-analysis for process of care and patient outcomes with reference to framework category. RESULTS: Twenty-five studies met the inclusion criteria. Twenty-one used a pre-post (no comparison), two a pre-post with a comparison, and two a cluster randomised trial design. Eleven theoretical implementation frameworks were prospectively applied: six process models; five determinant frameworks; and one classic theory. Four studies used two theoretical implementation frameworks. No authors reported their justification for selecting a particular framework and implementation strategies were generally poorly described. No consensus was reached for a preferred framework or subset of frameworks based on meta-analysis results. CONCLUSIONS: Rather than the ongoing development of new implementation frameworks, a more consistent approach to framework selection and strengthening of existing approaches is recommended to further develop the implementation evidence base.

Impact assessment of the Centre for Research Excellence in Stroke Rehabilitation and Brain Recovery.

BACKGROUND: Research impact is an emerging measure of research achievement alongside traditional academic outputs such as publications. We present the results of applying the Framework to Assess the Impact from Translational health research (FAIT) to the Centre for Research Excellence (CRE) in Stroke Rehabilitation and Brain Recovery (CRE-Stroke, 2014-2019) and report on the feasibility and lessons from the application of FAIT to a CRE rather than a discrete research project. METHODS: Data were gathered via online surveys, in-depth interviews, document analysis and review of relevant websites/databases to report on the three major FAIT methods: the modified Payback Framework, an assessment of costs against monetized consequences, and a narrative account of the impact generated from CRE-Stroke activities. FAIT was applied during the last 4 years of CRE-Stroke operation. RESULTS: With an economic investment of AU$ 3.9 million over 5 years, CRE-Stroke delivered a return on investment that included AU$ 18.8 million in leveraged grants, fellowships and consultancies. Collectively, CRE-Stroke members produced 354 publications that were accessed 470,000 times and cited over 7220 times. CRE-Stroke supported 26 PhDs, 39 postdocs and seven novice clinician researchers. There were 59 capacity-building events benefiting 744 individuals including policy-makers and consumers. CRE-Stroke created research infrastructure (including a research register of stroke survivors and a brain biobank), and its global leadership produced international consensus recommendations to influence the stroke research landscape worldwide. Members contributed to the Australian Living Stroke Guidelines: four researchers' outputs were directly referenced. Based only on the consequences that could be monetized, CRE-Stroke returned AU$ 4.82 for every dollar invested in the CRE. CONCLUSION: This case example in the developing field of impact assessment illustrates how researchers can use evidence to demonstrate and report the impact of and returns on research investment. The prospective application of FAIT by a dedicated research impact team demonstrated impact in broad categories of knowledge-gain, capacity-building, new infrastructure, input to policy and economic benefits. The methods can be used by other research teams to provide comprehensive evidence to governments and other research funders about what has been generated from their research investment but requires dedicated resources to complete.

Heart 2 Heart: Pilot Study of a Church-Based Community Health Worker Intervention for African Americans with Hypertension.

African Americans (AAs) have higher prevalence of uncontrolled hypertension than Whites, which leads to reduced life expectancy. Barriers to achieving blood pressure control in AAs include mistrust of healthcare and poor adherence to medication and dietary recommendations. We conducted a pilot study of a church-based community health worker (CHW) intervention to reduce blood pressure among AAs by providing support and strategies to improve diet and medication adherence. To increase trust and cultural concordance, we hired and trained church members to serve as CHWs. AA adults (n = 79) with poorly controlled blood pressure were recruited from churches in a low-income, segregated neighborhood of Chicago. Participants had an average of 7.5 visits with CHWs over 6 months. Mean change in systolic blood pressure across participants was - 5 mm/Hg (p = 0.029). Change was greater among participants (n = 45) with higher baseline blood pressure (- 9.2, p = 0.009). Medication adherence increased at follow-up, largely due to improved timeliness of medication refills, but adherence to the DASH diet decreased slightly. Intervention fidelity was poor. Recordings of CHW visits revealed that CHWs did not adhere closely to the intervention protocol, especially with regard to assisting participants with action plans for behavior change. Participants gave the intervention high ratings for acceptability and appropriateness, and slightly lower ratings for feasibility of achieving intervention behavioral targets. Participants valued having the intervention delivered at their church and preferred a church-based intervention to an intervention conducted in a clinical setting. A church-based CHW intervention may be effective at reducing blood pressure in AAs.

Management of Postpartum Hemorrhage in Critical Care Transport.

Postpartum hemorrhage is a relatively common and highly morbid complication of the postpartum period that often requires management by specialized providers at tertiary care facilities. Critical care transport teams may be tasked with transporting postpartum patients who are already experiencing postpartum hemorrhage, but they should also be aware that other peripartum patients may be at risk for developing postpartum hemorrhage while in the process of transport. As such, it is imperative that transport providers understand the signs, symptoms, causes, and complications of postpartum hemorrhage as well as the options for intervention and treatment. This article reviews the current clinical evidence regarding resuscitation and medical management strategies that transport teams should be familiar with as well as more advanced and invasive management techniques they may encounter and be expected to monitor during transport, such as balloon tamponade and aortic balloon occlusion.

HIV Treatment Outcomes in POP-UP: Drop-in HIV Primary Care Model for People Experiencing Homelessness.

BACKGROUND: People with HIV experiencing homelessness have low rates of viral suppression, driven by sociostructural barriers and traditional care system limitations. Informed by the capability-opportunity-motivation-behavior (COM-B) model and patient preference research, we developed POP-UP, an integrated drop-in (nonappointment-based) HIV clinic with wrap-around services for persons with housing instability and viral nonsuppression in San Francisco. METHODS: We report HIV viral suppression (VS; <200 copies/mL), care engagement, and mortality at 12 months postenrollment. We used logistic regression to determine participant characteristics associated with VS. RESULTS: We enrolled 112 patients with viral nonsuppression and housing instability: 52% experiencing street-homelessness, 100% with a substance use disorder, and 70% with mental health diagnoses. At 12 months postenrollment, 70% had ≥1 visit each 4-month period, although 59% had a 90-day care gap; 44% had VS, 24% had viral nonsuppression, 23% missing, and 9% died (6 overdose, 2 AIDS-associated, 2 other). No baseline characteristics were associated with VS. CONCLUSIONS: The POP-UP low-barrier HIV care model successfully reached and retained some of our clinic's highest-risk patients. It was associated with VS improvement from 0% at baseline to 44% at 12 months among people with housing instability. Care gaps and high mortality from overdose remain major challenges to achieving optimal HIV treatment outcomes in this population.

Racial and Ethnic Differences in Hospital Admissions of Emergency Department COVID-19 Patients.

BACKGROUND: Several studies have found that among patients testing positive for COVID-19 within a health care system, non-Hispanic Black and Hispanic patients are more likely than non-Hispanic White patients to be hospitalized. However, previous studies have looked at odds of being admitted using all positive tests in the system and not only those seeking care in the emergency department (ED). OBJECTIVE: This study examined racial/ethnic differences in COVID-19 hospitalizations and intensive care unit (ICU) admissions among patients seeking care for COVID-19 in the ED. RESEARCH DESIGN: Electronic health records (n=7549) were collected from COVID-19 confirmed patients that visited an ED of an urban health care system in the Chicago area between March 2020 and February 2021. RESULTS: After adjusting for possible confounders, White patients had 2.2 times the odds of being admitted to the hospital and 1.5 times the odds of being admitted to the ICU than Black patients. There were no observed differences between White and Hispanic patients. CONCLUSIONS: White patients were more likely than Black patients to be hospitalized after presenting to the ED with COVID-19 and more likely to be admitted directly to the ICU. This finding may be due to racial/ethnic differences in severity of disease upon ED presentation, racial and ethnic differences in access to COVID-19 primary care and/or implicit bias impacting clinical decision-making.

Fit for purpose. Co-production of complex behavioural interventions. A practical guide and exemplar of co-producing a telehealth-delivered exercise intervention for people with stroke.

BACKGROUND: Careful development of interventions using principles of co-production is now recognized as an important step for clinical trial development, but practical guidance on how to do this in practice is lacking. This paper aims (1) provide practical guidance for researchers to co-produce interventions ready for clinical trial by describing the 4-stage process we followed, the challenges experienced and practical tips for researchers wanting to co-produce an intervention for a clinical trial; (2) describe, as an exemplar, the development of our intervention package. METHOD: We used an Integrated Knowledge Translation (IKT) approach to co-produce a telehealth-delivered exercise program for people with stroke. The 4-stage process comprised of (1) a start-up planning phase with the co-production team. (2) Content development with knowledge user informants. (3) Design of an intervention protocol. (4) Protocol refinement. RESULTS AND REFLECTIONS: The four stages of intervention development involved an 11-member co-production team and 32 knowledge user informants. Challenges faced included balancing conflicting demands of different knowledge user informant groups, achieving shared power and collaborative decision making, and optimising knowledge user input. Components incorporated into the telehealth-delivered exercise program through working with knowledge user informants included: increased training for intervention therapists; increased options to tailor the intervention to participant's needs and preferences; and re-naming of the program. Key practical tips include ways to minimise the power differential between researchers and consumers, and ensure adequate preparation of the co-production team. CONCLUSION: Careful planning and a structured process can facilitate co-production of complex interventions ready for clinical trial.

Frailty as predictor of complications in patients undergoing percutaneous nephrolithotomy (PCNL).

INTRODUCTION & OBJECTIVE: Surgical complications are difficult to predict, despite existing tools. Frailty phenotype has shown promise estimating postoperative risk among the elderly. We evaluate the use of frailty as a predictive tool on patients undergoing percutaneous renal surgery. METHODS: Frailty was prospectively analyzed using the Hopkins Frailty Index, consisting of 5 components yielding an additive score: patients categorized not frail, intermediate, or severely frail. Primary outcomes were complications during admission and 30-day complication rate. Secondary outcomes included overall hospital length of stay (LOS) and discharge location. RESULTS: A total of 100 patients recruited, of whom five excluded as they did not need the procedure. A total of 95 patients analyzed; 69, 10, and 16 patients were not frail, intermediate, and severely frail, respectively. There were no differences in blood loss, number of dilations, presence of a staghorn calculus, laterality, or location of dilation. Severely frail patients were likely to be older and have a higher American Society of Anesthesiologists score and Charlson comorbidity index. Patients of intermediate or severe frailty were more likely to exhibit postoperative fevers, bacteremia, sepsis, and require ICU admissions (P < 0.05). Frail patients had a longer LOS (P < 0.001) and tended to require skilled assistance when discharge (p < 0.0001). CONCLUSIONS: Frailty assessment appears useful stratifying those at risk of extended hospitalization, septic complications, and need for assistance following percutaneous renal surgery. Risks of sepsis, bacteremia, and post-operative hemorrhage may be higher in frail individuals. Preoperative assessment of frailty phenotype may give insight into treatment decisions and represent a modifiable marker allowing future trials exploring the concept of "prehabilitation".

Secondary Prevention of Stroke: Study Protocol for a Telehealth-Delivered Physical Activity and Diet Pilot Randomized Trial (ENAbLE-Pilot).

BACKGROUND: Increasing physical activity (PA) and improving diet quality are opportunities to improve secondary stroke prevention, but access to appropriate services is limited. Interventions co-designed with stroke survivors and delivered by telehealth are a potential solution. AIM: The aim of this study is to test the feasibility, safety, and potential efficacy of a 6-month, telehealth-delivered PA and/or dietary (DIET) intervention. METHODS: Pilot randomized trial. 80 adults with previous stroke who are living at home with Internet access and able to exercise will be randomized in a 2 × 2 factorial (4-arm) pilot randomized, open-label, blinded outcome assessment trial to receive PA, DIET, PA + DIET, or control interventions via telehealth. The PA intervention aims to support participants to meet the minimum recommended levels of PA (150 min/week moderate exercise), and the DIET intervention aims to support participants to follow the AusMed (Mediterranean-style) diet. The control group receives usual care plus education about PA and healthy eating. The co-primary outcomes are feasibility (proportion and characteristics of eligible participants enrolled and proportion of scheduled intervention sessions attended) and safety (adverse events) at 6 months. The secondary outcomes include recurrent stroke risk factors (blood pressure, physical activity levels, and diet quality), fatigue, mood, and quality of life. Outcomes are measured at 3, 6, and 12 months. CONCLUSION: This trial will produce evidence for the feasibility, safety, and potential effect of telehealth-delivered PA and DIET interventions for people with stroke. Results will inform development of an appropriately powered trial to test effectiveness to reduce major risk factors for recurrent stroke. TRIAL REGISTRATION: ACTRN12620000189921.

Prioritizing guideline recommendations for implementation: a systematic, consumer-inclusive process with a case study using the Australian Clinical Guidelines for Stroke Management.

BACKGROUND: Implementation of evidence-based care remains a key challenge in clinical practice. Determining "what" to implement can guide implementation efforts. This paper describes a process developed to identify priority recommendations from clinical guidelines for implementation, incorporating the perspectives of both consumers and health professionals. A case study is presented where the process was used to prioritize recommendations for implementation from the Australian Stroke Clinical Guidelines. METHODS: The process was developed by a multidisciplinary group of researchers following consultation with experts in the field of implementation and stroke care in Australia. Use of the process incorporated surveys and facilitated workshops. Survey data were analysed descriptively; responses to ranking exercises were analysed via a graph theory-based voting system. RESULTS: The four-step process to identify high-priority recommendations for implementation comprised the following: (1) identifying key implementation criteria, which included (a) reliability of the evidence underpinning the recommendation, (b) capacity to measure change in practice, (c) a recommendation-practice gap, (d) clinical importance and (e) feasibility of making the recommended changes; (2) shortlisting recommendations; (3) ranking shortlisted recommendations and (4) reaching consensus on top priorities. The process was applied to the Australian Stroke Clinical Guidelines between February 2019 and February 2020. Seventy-five health professionals and 16 consumers participated. Use of the process was feasible. Three recommendations were identified as priorities for implementation from over 400 recommendations. CONCLUSION: It is possible to implement a robust process which involves consumers, clinicians and researchers to systematically prioritize guideline recommendations for implementation. The process is generalizable and could be applied in clinical areas other than stroke and in different geographical regions to identify implementation priorities. The identification of three clear priority recommendations for implementation from the Australian Stroke Clinical Guidelines will directly inform the development and delivery of national implementation strategies.

Interprofessional education in the rural environment to enhance multidisciplinary care in future practice: Breaking down silos in tertiary health education.

OBJECTIVE: Western Sydney University has implemented a rural interprofessional learning programme to promote collaborative care approaches to enhance cross-discipline communications, improve knowledge and clarity of roles and improve patient care and outcomes. DESIGN: Rural interprofessinal learning is an interprofessional educational approach, consisting of simulations of complex health events. Simulation methodology frames the study with a focus on human interaction. A mixed-methods evaluation has been conducted, incorporating pre- and post- event participant surveys along with semi-structured focus groups. SETTING: Simulations are conducted in the rural setting, including community settings, working farms and rural hospitals. MAIN OUTCOME MEASURES: Reflexive thematic analysis was used to identify themes measuring students' perceptions of interdisciplinary care, knowlede of other health discipline roles and skills and how they believe the exercise will influence their future practice. Facilitator feedback regarding the efficacy of the simulations was also recorded and analysed using reflexive thematic analysis. PARTICIPANTS: Care of simulated patient(s)/bystander(s) is primarily provided by paramedicine, nursing and medical students; however, increasing interest has expanded the programme to include students from a range of allied health professions. Simulations are facilitated by a multidisciplinary team of experienced practitioners and specialists. INTERVENTION: Four rural interprofessional learning events have been held. RESULTS: 120 students have participated in the evaluation. Findings include increased understanding of the contributions of other disciplines in enhancing patient care, team approaches, cross-discipline communication and a need to engage in collaborative care in future practice. CONCLUSION: Creating a collaborative learning environment creates a culture of multidisciplinary care, enhancing patient care and improving outcomes. The rural interprofessional learning model is an effective interprofessional educational approach, which can be repeated, refined and improved for continual professional development.

Identification of a Multipotent Progenitor Population in the Spleen That Is Regulated by NR4A1.

The developmental fate of hematopoietic stem and progenitor cells is influenced by their physiological context. Although most hematopoietic stem and progenitor cells are found in the bone marrow of the adult, some are found in other tissues, including the spleen. The extent to which the fate of stem cells is determined by the tissue in which they reside is not clear. In this study, we identify a new progenitor population, which is enriched in the mouse spleen, defined by cKit+CD71lowCD24high expression. This previously uncharacterized population generates exclusively myeloid lineage cells, including erythrocytes, platelets, monocytes, and neutrophils. These multipotent progenitors of the spleen (MPPS) develop from MPP2, a myeloid-biased subset of hematopoietic progenitors. We find that NR4A1, a transcription factor expressed by myeloid-biased long term-hematopoietic stem cells, guides the lineage specification of MPPS. In vitro, NR4A1 expression regulates the potential of MPPS to differentiate into erythroid cells. MPPS that express NR4A1 differentiate into a variety of myeloid lineages, whereas those that do not express NR4A1 primarily develop into erythroid cells. Similarly, in vivo, after adoptive transfer, Nr4a1-deficient MPPS contribute more to erythrocyte and platelet populations than do wild-type MPPS. Finally, unmanipulated Nr4a1-/- mice harbor significantly higher numbers of erythroid progenitors in the spleen compared with wild-type mice. Together, our data show that NR4A1 expression by MPPS limits erythropoiesis and megakaryopoeisis, permitting development to other myeloid lineages. This effect is specific to the spleen, revealing a unique molecular pathway that regulates myeloid bias in an extramedullary niche.
