Automatic segmentation and diameter measurement of deep medullary veins.

PURPOSE: As one of the pathogenic factors of cerebral small vessel disease, venous collagenosis may result in the occlusion or stenosis of deep medullary veins (DMVs). Although numerous DMVs can be observed in susceptibility-weighted MRI images, their diameters are usually smaller than the MRI resolution, making it difficult to segment them and quantify their sizes. We aim to automatically segment DMVs and measure their diameters from gradient-echo images. METHODS: A neural network model was trained for DMV segmentation based on the gradient-echo magnitude and phase images of 20 subjects at 7 T. The diameters of DMVs were obtained by fitting measured complex images with model images that accounted for the DMV-induced magnetic field and point spread function. A phantom study with graphite rods of different diameters was conducted to validate the proposed method. Simulation was carried out to evaluate the voxel-size dependence of measurement accuracy for a typical DMV size. RESULTS: The automatically segmented DMV masks had Dice similarity coefficients of 0.68 ± 0.03 (voxel level) and 0.83 ± 0.04 (cluster level). The fitted graphite-rod diameters closely matched their true values. In simulation, the fitted diameters closely matched the true value when voxel size was ≤ 0.45 mm, and 92.2% of DMVs had diameters between 90 µm and 200 µm with a peak at about 120 µm, which agreed well with an earlier ex vivo report. CONCLUSION: The proposed methods enabled efficient and quantitative study of DMVs, which may help illuminate the role of DMVs in the etiopathogenesis of cerebral small vessel disease.

Development of best practice guidelines for clinical and community service providers to prevent suicide in LGBTQA+ young people: A Delphi expert consensus study.

OBJECTIVE: The aim of this study was to develop best practice guidelines for preventing suicide and reducing suicidal thoughts and behaviours in LGBTQA+ young people (lesbian, gay, bisexual, trans, queer/questioning, asexual, and those of other diverse sexualities and genders) within clinical and community service settings in Australia. METHODS: We conducted a Delphi expert consensus study. A systematic literature search and interviews with key informants informed an initial 270-item questionnaire. Two expert panels completed the questionnaire, delivered over two rounds: (1) Australian professionals with expertise in LGBTQA+ mental health/suicide prevention and (2) Australian LGBTQA+ young people aged 14-25 with lived experience of suicidal thoughts and/or behaviours. Items endorsed as 'essential' or 'important' by >80% of both expert panels were included in the guidelines. RESULTS: A total of 115 people participated in the Delphi process; n = 52 professionals completed Round 1, and n = 42 completed Round 2; n = 63 LGBTQA+ young people completed Round 1, and n = 50 completed Round 2. A total of 290 items were included in the guidelines and grouped into: (1) general principles for creating an affirming and inclusive environment for LGBTQA+ young people; (2) assessing suicide risk and working with suicidal LGBTQA+ young people; (3) considerations for specific LGBTQA+ populations; and (4) advocating for LGBTQA+ young people. CONCLUSION: These guidelines are the first of their kind in Australia. They provide practical support to service providers regardless of prior training in LGBTQ+ identities or mental health, with the aim of reducing suicidal thoughts and behaviours, and preventing suicide, in LGBTQA+ young people.

Air pollution exposure during pregnancy and preterm birth in Brazil.

Ambient air pollution is a significant environmental risk factor for adverse pregnancy outcomes, including preterm birth. However, the impact of different pollutants across various regions and trimesters of pregnancy has not been fully investigated in Brazil. This study aimed to examine the associations between exposure to PM2.5, NO2, and O3 during different trimesters of pregnancy and the risk of preterm birth across five regions of Brazil. We used logistic regression models to estimate the odds ratios (OR) of preterm birth associated with PM2.5, NO2, and O3 adjusting for potential confounders such as maternal age, education, and socioeconomic status. Our study included over 9.9 million live births from 2001 to 2018, with data obtained from the Ministry of Health in Brazil. On average, for each 1-µg/m3 increase in PM2.5, we estimated a 0.26 % (95 % CI: 0.08-0.44 %) increase in the risk of preterm birth nationally in the first trimester. For NO2, each 1ppb increase was associated with a percentage increase in preterm birth risk of 7.26 % (95 % CI: 4.77-9.74 %) in the first trimester, 8.05 % (95 % CI: 5.73-10.38 %) in the second trimester, and 7.48 % (95 % CI: 5.25-9.72 %) in the third trimester. For O3, each 1ppb increase was associated with a percentage increase in preterm birth risk of 1.24 % (95 % CI: 0.29-2.18 %) in the first trimester, 1.51 % (95 % CI: 0.60-2.41 %) in the second trimester, and 0.72 % (95 % CI: -0.18-1.62 %) in the third trimester. This study highlights the significant impact of ambient air pollution on preterm birth risk in Brazil, with significant regional variations. Our findings underscore the need for targeted public health interventions to mitigate the effects of air pollution on pregnancy outcomes, particularly in the most affected regions.

Phase 1b study of combined selinexor and eribulin for the treatment of advanced solid tumors and triple-negative breast cancer.

BACKGROUND: Selinexor (KPT-330) is a potent inhibitor of exportin 1 (XPO1), in turn inhibiting tumor growth. Selinexor enhances the antitumor efficacy of eribulin in triple-negative breast cancer (TNBC) in vitro and in vivo. Given the unmet medical need in TNBC and sarcoma, the authors explored the safety and efficacy of this combination. METHODS: The authors conducted a phase 1b trial of combined selinexor and eribulin using a 3 + 3 dose-escalation design in patients who had advanced solid tumors and in those who had TNBC in a dose-expansion cohort. RESULTS: Patients with TNBC (N = 19), sarcoma (N = 9), and other cancers (N = 3) were enrolled in the dose-escalation cohort (N = 10) and in the dose-expansion cohort (N = 21). The median number lines of prior therapy received was four (range, from one to seven prior lines). The most common treatment-related adverse events for selinexor were nausea (77%), leukopenia (77%), anemia (68%), neutropenia (68%), and fatigue (48%). One dose-limiting toxicity occurred at the first dose level with prolonged grade 3 neutropenia. The recommended phase 2 dose was 80 mg of selinexor orally once per week and 1 mg/m2 eribulin on days 1 and 8 intravenously every 3 weeks. The objective response rate (ORR) was 10% in three patients. In the dose-escalation cohort, the ORR was 10%, whereas six patients with had stable disease. In the TNBC dose-expansion cohort (n = 18), ORR was 11%, and there were two confirmed partial responses with durations of 10.8 and 19.1 months (ongoing). CONCLUSIONS: Selinexor and eribulin had an acceptable toxicity profile and modest overall efficacy with durable responses in select patients. PLAIN LANGUAGE SUMMARY: Effective therapies for advanced, triple-negative breast cancer and sarcoma represent an unmet need. Exportin 1 is associated with the transport of cancer-related proteins. Preclinical studies have demonstrated tumor growth inhibition and enhanced tumor sensitivity in patients who receive selinexor combined with eribulin. In this phase 1b study, the authors evaluated the safety profile and clinical activity of the combination of selinexor, a potent oral inhibitor of exportin 1, and eribulin in patients with advanced cancers enriched for triple-negative breast cancer or sarcoma. The combination was well tolerated; most adverse events were mild or moderate, reversible, and managed with dose modifications or growth factor support. The combination of selinexor and eribulin produced an antitumor response, particularly in some patients with triple-negative breast cancer. This work lays the foundation for prospective investigations of the role of selinexor and eribulin in the treatment of triple-negative breast cancer.

Gender non-conformity in childhood and adolescence and mental health through to adulthood: a longitudinal cohort study, 1995-2018.

BACKGROUND: Few studies have examined associations between gender non-conformity (GNC) in childhood or adolescence and mental health outcomes later in life. This study examined associations between (1) GNC and mental health over multiple time points in childhood and adolescence, and (2) GNC in childhood and/or adolescence and mental health in adulthood. METHOD: Second generation participants from the Raine Study, a longitudinal cohort from Perth, Western Australia. Data were collected between 1995 and 2018, comprising seven waves: ages 5 (N = 2236), 8 (N = 2140), 10 (N = 2048), 14 (N = 1864), 17 (N = 1726), 22 (N = 1236) and 27 (N = 1190) years. History of GNC, v. absence of this history, was based on responses to item 110 from the Child Behaviour Checklist (CBCL)/Youth Self Report (YSR) ('wishes to be of opposite sex'). The CBCL/YSR were used to measure internalising and externalising symptoms. Items 18 ('deliberate self-harm [DSH] or attempts suicide') and 91 ('talks/thinks about killing self') were used as measures of suicidal ideation (SI) and DSH. For adults, Depression, Anxiety and Stress Subscales and Kessler Psychological Distress Scale assessed mental health. RESULTS: Child and adolescent GNC was associated with elevated internalising and externalising behaviours and increased odds of DSH. A history of GNC was also associated with vulnerability for severe psychological distress in adulthood in some symptom scales. CONCLUSION: GNC over the child and adolescent period is associated with significant emotional and behavioural difficulties, and psychological distress. A history of GNC in childhood and/or adolescence also predicts poorer mental health in adulthood on multiple symptom domains.

Implementation strategies to promote compassionate nursing care of complex patients: An exploratory sequential mixed methods study.

INTRODUCTION: Individuals with multiple physical and, or, mental health issues and, or, drug-related problems are known as complex patients. These patients are often recipients of poor-quality care. Compassionate nursing care is valuable to promote better care experiences among this patient population. Implementation strategies should be designed to enhance compassionate nursing care delivery. The study aimed to gain understanding of barriers to compassionate care delivery to propose implementation to promote compassionate nursing care of complex patients. DESIGN: An exploratory sequential mixed methods study was conducted. METHODS: Phase 1 was the qualitative component during which 23 individuals with multimorbidities were interviewed for exploring their perceptions of barriers to compassionate nursing care. The barriers were integrated with implementation science frameworks using the building technique during phase 2 to develop a Q-sort survey of implementation strategies for phase 3. Nurses, nurse managers, health care administrators, policymakers, and compassionate care experts responded to the survey by ranking the 21 implementation strategies, out of which five met the Q-factor analysis criteria. RESULTS: Participant-perceived barriers to nurse compassion could be categorized under knowledge, intentions, skills, social influences, behavioral regulation, reinforcement, emotion, and environmental context and resources. The five highest-ranked strategies included facilitation, consultation with stress experts, involvement of patients and families, modeling compassion through shadowing, and utilizing implementation teams. CONCLUSIONS: Enablement and modeling were the integration functions represented by the highest-ranked implementation strategies. Enabling nurses to provide compassionate care through emotional support and mental health counseling, and, modeling compassion and compassionate care through shadowing were recommended and rated as highly relevant by the majority of stakeholders. CLINICAL RELEVANCE: Enhancing nurses compassionate behaviors toward complex patients requires facilitating them in enacting compassion in practice through modeling and support from organizations and nurse managers.

Behavioural indicators of compassionate nursing care of individuals with complex needs: A naturalistic inquiry.

AIMS AND OBJECTIVES: To explore behavioural indicators of compassionate nursing care from the perspectives of individuals with multimorbidities and complex needs. BACKGROUND: Complex patients are individuals with multimorbidity and/or mental health concerns, andoften with medication and drug-related problems requiring ongoing person-centered care, mental health interventions, and family and community resources. They are frequent consumers of health-care services and it is documented that these patients experience discrimination and substandard care. Compassionate care can improve patient care experiences and health outcomes. However, missing is the guidance on how to provide compassionate care for this population from the perspectives of complex patients. DESIGN: A qualitative descriptive approach was conducted in eastern Canada from December 2020-April 2021. The COREQ guidelines were followed for reporting. METHODS: Data from in-person and virtual semi-structured interviews with 23 individuals having experiences as complex patients were analysed using reflexive thematic analysis. Among them 19 were homeless and lived in a shelter. FINDINGS: Six indicators of compassionate nursing care were generated: sensitivity, awareness, a non-judgmental approach, a positive demeanour, empathic understanding, and altruism. CONCLUSIONS: Individuals perceived that nurses who acknowledge personal biases are better at providing compassionate care by manifesting compassion through their genuine and selfless interest in the complicated health problems and underlying socio-cultural determinants of each patient. Kindness, positivity, and a respectful nursing approach elicit openness and the sharing of heartfelt concerns. RELEVANCE TO CLINICAL PRACTICE: Comprehensive health assessment, dedicated efforts to know the patient as a human being, and listening to the patient's preferences can improve health outcomes among individuals with complex needs. Healthcare administrators can effect the change by supporting nurses to address complex health and social care needs with compassion. PATIENT OR PUBLIC CONTRIBUTION: Patients and healthcare professionals helped in data collection at the community care centre.

The impact of facilitators and rural immersion on medical student engagement during a child and adolescent mental health videoconference workshop.

OBJECTIVE: Child and adolescent mental health (CAMH) disorders are a major public health problem in Australia, especially outside metropolitan areas. The issue is compounded by a shortage of child and adolescent psychiatrists (CAPs). CAMH receives minimal coverage in health professional training, training opportunities are scarce, and support for generalist health professionals, who treat most cases, is lacking. Novel approaches to early medical education and teaching are required to strengthen the available skilled workforce in rural and remote settings. METHOD: This qualitative study explored the factors influencing medical student engagement in a CAMH videoconferencing workshop as part of the Rural Clinical School of WA. RESULTS: Our results confirm the priority of personal characteristics of medical educators, over clinical and subject matter expertise, on student learning. This research affirms that general practitioners are well-placed to facilitate recognition of learning experiences, especially given that students may not readily recognise exposure to CAMH cases. CONCLUSION: Our findings support the effectiveness, efficiencies, and benefits of utilising general medical educators in supporting child and adolescent psychiatry expertise in delivering subspecialty training within medical school curricula.

Prospective motion correction and automatic segmentation of penetrating arteries in phase contrast MRI at 7 T.

PURPOSE: To develop a prospective motion correction (MC) method for phase contrast (PC) MRI of penetrating arteries (PAs) in centrum semiovale at 7 T and to evaluate its performance using automatic PA segmentation. METHODS: Head motion was monitored and corrected during the scan based on fat navigator images. Two convolutional neural networks (CNN) were developed to automatically segment PAs and exclude surface vessels. Real-life scans with MC and without MC (NoMC) were performed to evaluate the MC performance. Motion score was calculated from the ranges of translational and rotational motion parameters. MC versus NoMC pairs with similar motion scores during MC and NoMC scans were compared. Data corrupted by motion were reacquired to further improve PA visualization. RESULTS: PA counts (NPA ) and PC and magnitude contrasts (MgC) relative to neighboring tissue were significantly correlated with motion score and were higher in MC than NoMC images at motion scores above 0.5-0.8 mm. Data reacquisition further increased PC but had no significant effect on NPA and MgC. CNNs had higher sensitivity and Dice similarity coefficient for detecting PAs than a threshold-based method. CONCLUSIONS: Prospective MC can improve the count and contrast of segmented PAs in the presence of severe motion. CNN-based PA segmentation has improved performance in delineating PAs than the threshold-based method.

Selecting implementation models, theories, and frameworks in which to integrate intersectional approaches.

BACKGROUND: Models, theories, and frameworks (MTFs) provide the foundation for a cumulative science of implementation, reflecting a shared, evolving understanding of various facets of implementation. One under-represented aspect in implementation MTFs is how intersecting social factors and systems of power and oppression can shape implementation. There is value in enhancing how MTFs in implementation research and practice account for these intersecting factors. Given the large number of MTFs, we sought to identify exemplar MTFs that represent key implementation phases within which to embed an intersectional perspective. METHODS: We used a five-step process to prioritize MTFs for enhancement with an intersectional lens. We mapped 160 MTFs to three previously prioritized phases of the Knowledge-to-Action (KTA) framework. Next, 17 implementation researchers/practitioners, MTF experts, and intersectionality experts agreed on criteria for prioritizing MTFs within each KTA phase. The experts used a modified Delphi process to agree on an exemplar MTF for each of the three prioritized KTA framework phases. Finally, we reached consensus on the final MTFs and contacted the original MTF developers to confirm MTF versions and explore additional insights. RESULTS: We agreed on three criteria when prioritizing MTFs: acceptability (mean = 3.20, SD = 0.75), applicability (mean = 3.82, SD = 0.72), and usability (median = 4.00, mean = 3.89, SD = 0.31) of the MTF. The top-rated MTFs were the Iowa Model of Evidence-Based Practice to Promote Quality Care for the 'Identify the problem' phase (mean = 4.57, SD = 2.31), the Consolidated Framework for Implementation Research for the 'Assess barriers/facilitators to knowledge use' phase (mean = 5.79, SD = 1.12), and the Behaviour Change Wheel for the 'Select, tailor, implement interventions' phase (mean = 6.36, SD = 1.08). CONCLUSIONS: Our interdisciplinary team engaged in a rigorous process to reach consensus on MTFs reflecting specific phases of the implementation process and prioritized each to serve as an exemplar in which to embed intersectional approaches. The resulting MTFs correspond with specific phases of the KTA framework, which itself may be useful for those seeking particular MTFs for particular KTA phases. This approach also provides a template for how other implementation MTFs could be similarly considered in the future. TRIAL REGISTRATION: Open Science Framework Registration: osf.io/qgh64.

Development and usability testing of tools to facilitate incorporating intersectionality in knowledge translation.

BACKGROUND: The field of knowledge translation (KT) has been criticized for neglecting contextual and social considerations that influence health equity. Intersectionality, a concept introduced by Black feminist scholars, emphasizes how human experience is shaped by combinations of social factors (e.g., ethnicity, gender) embedded in systemic power structures. Its use has the potential to advance equity considerations in KT. Our objective was to develop and conduct usability testing of tools to support integrating intersectionality in KT through three key phases of KT: identifying the gap; assessing barriers to knowledge use; and selecting, tailoring, and implementing interventions. METHODS: We used an integrated KT approach and assembled an interdisciplinary development committee who drafted tools. We used a mixed methods approach for usability testing with KT intervention developers that included semi-structured interviews and the System Usability Scale (SUS). We calculated an average SUS score for each tool. We coded interview data using the framework method focusing on actionable feedback. The development committee used the feedback to revise tools, which were formatted by a graphic designer. RESULTS: Nine people working in Canada joined the development committee. They drafted an intersectionality primer and one tool that included recommendations, activities, reflection prompts, and resources for each of the three implementation phases. Thirty-one KT intervention developers from three countries participated in usability testing. They suggested the tools to be shorter, contain more visualizations, and use less jargon. Average SUS scores of the draft tools ranged between 60 and 78/100. The development committee revised and shortened all tools, and added two, one-page summary documents. The final toolkit included six documents. CONCLUSIONS: We developed and evaluated tools to help embed intersectionality considerations in KT. These tools go beyond recommending the use of intersectionality to providing practical guidance on how to do this. Future work should develop guidance for enhancing social justice in intersectionality-enhanced KT.

Promoting Social and Emotional Learning in Middle School: Intervention Effects of Facing History and Ourselves.

There are fewer evidence-based social and emotional learning programs for middle school students compared to younger grades. This randomized controlled trial tests the effectiveness of Facing History and Ourselves (hereafter, Facing History) with a sample of 694 (Facing History n = 437; Comparison n = 257) students from a low-resourced school district. Youth self-identified as female (59%), Black/African American (61%), Hispanic/Latinx (18%), White (2%), and multi-racial or some other race/ethnicity (19%). Intervention students perceived their classrooms as more caring and democratic than students in the comparison group. They reported higher levels of empathy, prosocial behavior, and stronger participatory citizenship beliefs. This study expands the evidence-based of effective SEL programs available to schools.

The Fixed Childfree Subjectivity: Performing Meta-Facework about Sterilization on Reddit.

Although sterilization is the most common and effective form of birth control available, childfree individuals often report difficulty actually obtaining the procedure. The ideological and material constraints that impede access have been well documented, including physicians' pronatalist perceptions that childless women will regret sterilization when they mature or meet the right partner. However, researchers have demonstrated that childfree women experience low levels of regret after sterilization, indicating that physicians' reluctance is empirically unfounded. In order to mitigate physicians' hesitancy, childfree individuals organize and communicate online in order to share health-related information, seek support, and engage in identity work to more effectively procure the procedure. The current study contributes to critical health, interpersonal, and family communication conversations by employing performative face theory to study online interactions on the childfree subreddit, the largest and most active online forum dedicated to child freedom. Through critical-qualitative analysis of a cross-section of subreddit posts about sterilization, this study demonstrates how subreddit discourse draws upon ideological and metaphorical associations to articulate the fixed childfree subjectivity, which rejects negative significations of regret in favor of positive notions of repair and permanence. Users further engage in subversive meta-facework, or facework presented online about facework users engaged in offline, which maintains shared face and denaturalizes taken-for-granted linkages between gender, identity, and parenthood. Implications for health activism across individual, relational, communal, and cultural levels are discussed.

Applying an intersectionality lens to the theoretical domains framework: a tool for thinking about how intersecting social identities and structures of power influence behaviour.

BACKGROUND: A key component of the implementation process is identifying potential barriers and facilitators that need to be addressed. The Theoretical Domains Framework (TDF) is one of the most commonly used frameworks for this purpose. When applying the TDF, it is critical to understand the context in which behaviours occur. Intersectionality, which accounts for the interface between social identity factors (e.g. age, gender) and structures of power (e.g. ageism, sexism), offers a novel approach to understanding how context shapes individual decision-making and behaviour. We aimed to develop a tool to be used alongside applications of the TDF to incorporate an intersectionality lens when identifying implementation barriers and enablers. METHODS: An interdisciplinary Framework Committee (n = 17) prioritized the TDF as one of three models, theories, and frameworks (MTFs) to enhance with an intersectional lens through a modified Delphi approach. In collaboration with the wider Framework Committee, a subgroup considered all 14 TDF domains and iteratively developed recommendations for incorporating intersectionality considerations within the TDF and its domains. An iterative approach aimed at building consensus was used to finalize recommendations. RESULTS: Consensus on how to apply an intersectionality lens to the TDF was achieved after 12 rounds of revision. Two overarching considerations for using the intersectionality alongside the TDF were developed by the group as well as two to four prompts for each TDF domain to guide interview topic guides. Considerations and prompts were designed to assist users to reflect on how individual identities and structures of power may play a role in barriers and facilitators to behaviour change and subsequent intervention implementation. CONCLUSIONS: Through an expert-consensus approach, we developed a tool for applying an intersectionality lens alongside the TDF. Considering the role of intersecting social factors when identifying barriers and facilitators to implementing research evidence may result in more targeted and effective interventions that better reflect the realities of those involved.

Functional connectivity of the vigilant-attention network in children and adolescents with attention-deficit/hyperactivity disorder.

The ability to maintain attention to simple tasks (i.e., vigilant attention, VA) is often impaired in attention-deficit/hyperactivity disorder (ADHD), but the underlying pathophysiological mechanisms at the brain network level are not clear yet. We therefore investigated ADHD-related differences in resting-state functional connectivity within a meta-analytically defined brain network of 14 distinct regions subserving VA (comprising 91 connections in total), as well as the association of connectivity with markers of behavioural dysfunction in 17 children (age range: 9-14 years) with a diagnosis of ADHD and 21 age-matched neurotypical controls. Our analyses revealed selective, rather than global, differences in the intrinsic coupling between nodes of the VA-related brain network in children with ADHD, relative to controls. In particular, ADHD patients showed substantially diminished intrinsic coupling for 7 connections and increased coupling for 4 connections, with many differences involving connectivity with the anterior insula. Moreover, connectivity strength of several aberrant connections was found to be associated with core aspects of ADHD symptomatology, such as poor attention, difficulties with social functioning, and impaired cognitive control, attesting to the behavioural relevance of specific connectivity differences observed in the resting state.

Can the effects of the mobilization of vulnerable elders in Ontario (MOVE ON) implementation be replicated in new settings: an interrupted time series design.

BACKGROUND: Bed rest for older hospitalized patients places them at risk for hospital-acquired morbidity. We previously evaluated an early mobilization intervention and found it to be effective at improving mobilization rates and decreasing length of stay on internal medicine units. The aim of this study was to conduct a replication study evaluating the impact of the evidence-informed mobilization intervention on surgery, psychiatry, medicine, and cardiology inpatient units. METHODS: A multi-component early mobilization intervention was tailored to the local context at seven hospitals in Ontario, Canada. The primary outcome was patient mobilization measured by conducting visual audits twice a week, three times a day. Secondary outcomes were hospital length of stay and discharge destination, which were obtained from hospital decision support data. The study population was patients aged 65 years and older who were admitted to surgery, psychiatry, medicine, and cardiology inpatient units between March and August 2014. Using an interrupted time series design, the intervention was evaluated over three time periods-pre-intervention, during, and post-intervention. RESULTS: A total of 3098 patients [mean age 78.46 years (SD 8.38)] were included in the overall analysis. There was a significant increase in mobility immediately after the intervention period compared to pre-intervention with a slope change of 1.91 (95% confidence interval [CI] 0.74-3.08, P-value = 0.0014). A decreasing trend in median length of stay was observed in the majority of the participating sites. Overall, a median length of stay of 26.24 days (95% CI 23.67-28.80) was observed pre-intervention compared to 23.81 days (95% CI 20.13-27.49) during the intervention and 24.69 days (95% CI 22.43-26.95) post-intervention. The overall decrease in median length of stay was associated with the increase in mobility across the sites. CONCLUSIONS: MOVE increased mobilization and these results were replicated across surgery, psychiatry, medicine, and cardiology inpatient units.

Scaling-up implementation in community hospitals: a multisite interrupted time series design of the Mobilization of Vulnerable Elders (MOVE) program in Alberta.

BACKGROUND: As the population ages, older hospitalized patients are at increased risk for hospital-acquired morbidity. The Mobilization of Vulnerable Elders (MOVE) program is an evidence-informed early mobilization intervention that was previously evaluated in Ontario, Canada. The program was effective at improving mobilization rates and decreasing length of stay in academic hospitals. The aim of this study was to scale-up the program and conduct a replication study evaluating the impact of the evidence-informed mobilization intervention on various units in community hospitals within a different Canadian province. METHODS: The MOVE program was tailored to the local context at four community hospitals in Alberta, Canada. The study population was patients aged 65 years and older who were admitted to medicine, surgery, rehabilitation and intensive care units between July 2015 and July 2016. The primary outcome was patient mobilization measured by conducting visual audits twice a week, three times a day. The secondary outcomes included hospital length of stay obtained from hospital administrative data, and perceptions of the intervention assessed through a qualitative assessment. Using an interrupted time series design, the intervention was evaluated over three time periods (pre-intervention, during, and post-intervention). RESULTS: A total of 3601 patients [mean age 80.1 years (SD = 8.4 years)] were included in the overall analysis. There was a significant increase in mobilization at the end of the intervention period compared to pre-intervention, with 6% more patients out of bed (95% confidence interval (CI) 1, 11; p-value = 0.0173). A decreasing trend in median length of stay was observed, where patients on average stayed an estimated 3.59 fewer days (95%CI -15.06, 7.88) during the intervention compared to pre-intervention period. CONCLUSIONS: MOVE is a low-cost, effective and adaptable intervention that improves mobilization in older hospitalized patients. This intervention has been replicated and scaled up across various units and hospital settings.

The perceived organizational impact of the gender gap across a Canadian department of medicine and proposed strategies to combat it: a qualitative study.

BACKGROUND: Despite the gender parity existing in medical schools for over three decades, women remain underrepresented in academic medical centers, particularly in senior ranks and in leadership roles. This has consequences for patient care, education, research, and workplace culture within healthcare organizations. This study was undertaken to explore the perspectives of faculty members at a single department of medicine on the impact of the existing gender gap on organizational effectiveness and workplace culture, and to identify systems-based strategies to mitigate the gap. METHODS: The study took place at a large university department of medicine in Toronto, Canada, with six affiliated hospitals. In this qualitative study, semi-structured individual interviews were conducted between May and September 2016 with full-time faculty members who held clinical and university-based appointments. Transcripts of the interviews were analyzed using thematic analysis. Three authors independently reviewed the transcripts to determine a preliminary list of codes and establish a coding framework. A modified audit consensus coding approach was applied; a single analyst reviewed all the transcripts and a second analyst audited 20% of the transcripts in each round of coding. Following each round, inter-rater reliability was determined, discrepancies were resolved through discussion, and modifications were made as needed to the coding framework. The analysis revealed faculty members' perceptions of the gender gap, potential contributing factors, organizational impacts, and possible solutions to bridge the gap. RESULTS: Of the 43 full-time faculty members who participated in the survey (29 of whom self-identified as female), most participants were aware of the existing gender gap within academic medicine. Participants described social exclusion, reinforced stereotypes, and unprofessional behaviors as consequences of the gap on organizational effectiveness and culture. They suggested improvements in (1) the processes for recruitment, hiring, and promotion; (2) inclusiveness of the work environment; (3) structures for mentorship; and (4) ongoing monitoring of the gap. CONCLUSION: The existing gender gap in academic medicine may have negative consequences for organizational effectiveness and workplace culture but many systems-based strategies to mitigate the gap exist. Although these solutions warrant rigorous evaluation, they are feasible to institute within most healthcare organizations immediately.

Outcomes of Mobilisation of Vulnerable Elders in Ontario (MOVE ON): a multisite interrupted time series evaluation of an implementation intervention to increase patient mobilisation.

Background: older patients admitted to hospitals are at risk for hospital-acquired morbidity related to immobility. The aim of this study was to implement and evaluate an evidence-based intervention targeting staff to promote early mobilisation in older patients admitted to general medical inpatient units. Methods: the early mobilisation implementation intervention for staff was multi-component and tailored to local context at 14 academic hospitals in Ontario, Canada. The primary outcome was patient mobilisation. Secondary outcomes included length of stay (LOS), discharge destination, falls and functional status. The targeted patients were aged ≥ 65 years and admitted between January 2012 and December 2013. The intervention was evaluated over three time periods-pre-intervention, during and post-intervention using an interrupted time series design. Results: in total, 12,490 patients (mean age 80.0 years [standard deviation 8.36]) were included in the overall analysis. An increase in mobilisation was observed post-intervention, where significantly more patients were out of bed daily (intercept difference = 10.56%, 95% CI: [4.94, 16.18]; P < 0.001) post-intervention compared to pre-intervention. Hospital median LOS was significantly shorter during the intervention period (intercept difference = -3.45 days, 95% CI: [-6.67,-0.23], P = 0.0356) compared to pre-intervention. It continued to decrease post-intervention with significantly fewer days in hospital (intercept difference= -6.1, 95% CI: [-11,-1.2]; P = 0.015) in the post-intervention period compared to pre-intervention. Conclusions: this is a large-scale study evaluating an implementation strategy for early mobilisation in older, general medical inpatients. The positive outcome of this simple intervention on an important functional goal of getting more patients out of bed is a striking success for improving care for hospitalised older patients.

Supporting the implementation of stroke quality-based procedures (QBPs): a mixed methods evaluation to identify knowledge translation activities, knowledge translation interventions, and determinants of implementation across Ontario.

BACKGROUND: In 2013, Health Quality Ontario introduced stroke quality-based procedures (QBPs) to promote use of evidence-based practices for patients with stroke in Ontario hospitals. The study purpose was to: (a) describe the knowledge translation (KT) interventions used to support stroke QBP implementation, (b) assess differences in the planned and reported KT interventions by region, and (c) explore determinants perceived to have affected outcomes. METHODS: A mixed methods approach was used to evaluate: activities, KT interventions, and determinants of stroke QBP implementation. In Phase 1, a document review of regional stroke network work plans was conducted to capture the types of KT activities planned at a regional level; these were mapped to the knowledge to action framework. In Phase 2, we surveyed Ontario hospital staff to identify the KT interventions used to support QBP implementation at an organizational level. Phase 3 involved qualitative interviews with staff to elucidate deeper understanding of survey findings. RESULTS: Of the 446 activities identified in the document review, the most common were 'dissemination' (24.2%; n = 108), 'implementation' (22.6%; n = 101), 'implementation planning' (15.0%; n = 67), and 'knowledge tools' (10.5%; n = 47). Based on survey data (n = 489), commonly reported KT interventions included: staff educational meetings (43.1%; n = 154), champions (41.5%; n = 148), and staff educational materials (40.6%; n = 145). Survey participants perceived stroke QBP implementation to be successful (median = 5/7; interquartile range = 4-6; range = 1-7; n = 335). Forty-four people (e.g., managers, senior leaders, regional stroke network representatives, and frontline staff) participated in interviews/focus groups. Perceived facilitators to QBP implementation included networks and collaborations with external organizations, leadership engagement, and hospital prioritization of stroke QBP. Perceived barriers included lack of funding, size of the hospital (i.e., too small), lack of resources (i.e., staff and time), and simultaneous implementation of other QBPs. CONCLUSIONS: Information on the types of activities and KT interventions used to support stroke QBP implementation and the key determinants influencing uptake of stroke QBPs can be used to inform future activities including the development and evaluation of interventions to address barriers and leverage facilitators.
