Factors influencing health-related quality of life among long-term care residents experiencing pain: a systematic review protocol.

BACKGROUND: Pain is highly burdensome, affecting over 30% of long-term care (LTC) residents. Pain significantly reduces residents' health-related quality of life (HRQoL), limits their ability to perform activities of daily living (ADLs), restricts their social activities, and can lead to hopelessness, depression, and unnecessary healthcare costs. Although pain can generally be prevented or treated, eliminating pain may not always be possible, especially when residents have multiple chronic conditions. Therefore, improving the HRQoL of LTC residents with pain is a priority goal. Understanding factors influencing HRQoL of LTC residents with pain is imperative to designing and evaluating targeted interventions that complement pain management to improve residents' HRQoL. However, these factors are poorly understood, and we lack syntheses of available research on this topic. This systematic review protocol outlines the methods to identify, synthesize, and evaluate the available evidence on these factors. METHODS: This mixed methods review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We will systematically search Medline, EMBASE, PsycINFO, CINAHL, Scopus, Cochrane Database of Systematic Reviews and ProQuest Dissertation and Thesis Global from database inception. We will include primary studies and systematically conducted reviews without restrictions to language, publication date, and study design. We will also include gray literature (dissertation and reports) and search relevant reviews and reference lists of all included studies. Two reviewers will independently screen articles, conduct quality appraisal, and extract data. We will synthesize results thematically and conduct meta-analyses if statistical pooling is possible. Residents and family/friend caregivers will assist with interpreting the findings. DISCUSSION: This proposed systematic review will address an important knowledge gap related to the available evidence on factors influencing HRQoL of LTC residents with pain. Findings will be crucial for researchers, LTC administrators, and policy makers in uncovering research needs and in planning, developing, and evaluating strategies in addition to and complementary with pain management to help improve HRQoL among LTC residents with pain.

Safer Care for Older Persons in (residential) Environments (SCOPE): a pragmatic controlled trial of a care aide-led quality improvement intervention.

BACKGROUND: The increased complexity of residents and increased needs for care in long-term care (LTC) have not been met with increased staffing. There remains a need to improve the quality of care for residents. Care aides, providers of the bulk of direct care, are well placed to contribute to quality improvement efforts but are often excluded from so doing. This study examined the effect of a facilitation intervention enabling care aides to lead quality improvement efforts and improve the use of evidence-informed best practices. The eventual goal was to improve both the quality of care for older residents in LTC homes and the engagement and empowerment of care aides in leading quality improvement efforts. METHODS: Intervention teams participated in a year-long facilitative intervention which supported care aide-led teams to test changes in care provision to residents using a combination of networking and QI education meetings, and quality advisor and senior leader support. This was a controlled trial with random selection of intervention clinical care units matched 1:1 post hoc with control units. The primary outcome, between group change in conceptual research use (CRU), was supplemented by secondary staff- and resident-level outcome measures. A power calculation based upon pilot data effect sizes resulted in a sample size of 25 intervention sites. RESULTS: The final sample included 32 intervention care units matched to 32 units in the control group. In an adjusted model, there was no statistically significant difference between intervention and control units for CRU or in secondary staff outcomes. Compared to baseline, resident-adjusted pain scores were statistically significantly reduced (less pain) in the intervention group (p=0.02). The level of resident dependency significantly decreased statistically for residents whose teams addressed mobility (p<0.0001) compared to baseline. CONCLUSIONS: The Safer Care for Older Persons in (residential) Environments (SCOPE) intervention resulted in a smaller change in its primary outcome than initially expected resulting in a study underpowered to detect a difference. These findings should inform sample size calculations of future studies of this nature if using similar outcome measures. This study highlights the problem with measures drawn from current LTC databases to capture change in this population. Importantly, findings from the trial's concurrent process evaluation provide important insights into interpretation of main trial data, highlight the need for such evaluations of complex trials, and suggest the need to consider more broadly what constitutes "success" in complex interventions.

Developing a tool to measure enactment of complex quality improvement interventions in healthcare.

Quality improvement (QI) projects are common in healthcare settings and often involve interdisciplinary teams working together towards a common goal. Many interventions and programmes have been introduced through research to convey QI skills and knowledge to healthcare workers, however, a few studies have attempted to differentiate between what individuals 'learn' or 'know' versus their capacity to apply their learnings in complex healthcare settings. Understanding and differentiating between delivery, receipt, and enactment of QI skills and knowledge is important because while enactment alone does not guarantee desired QI outcomes, it might be reasonably assumed that 'better enactment' is likely to lead to better outcomes. This paper describes the development, application and validation of a tool to measure enactment of core QI skills and knowledge of a complex QI intervention in a healthcare setting. Based on the Institute for Healthcare Improvement's Model for Improvement, existing QI assessment tools, literature on enactment fidelity and our research protocols, 10 indicators related to core QI skills and knowledge were determined. Definitions and assessment criteria were tested and refined in five iterative cycles. Qualitative data from four QI teams in long-term care homes were used to test and validate the tool. The final measurement tool contains 10 QI indicators and a five-point scale. Inter-rater reliability ranged from good to excellent. Usability and acceptability among raters were considered high. This measurement tool assists in identifying strengths and weaknesses of a QI team and allows for targeted feedback on core QI components. The indicators developed in our tool and the approach to tool development may be useful in other health related contexts where similar data are collected.

Healthcare aide-focused interventions to improve pain management in long-term care homes: A systematic review.

OBJECTIVES: Pain is common in long-term care residents. We examined the effectiveness of interventions involving healthcare aides that aim to manage pain for these residents. DESIGN: A systematic review which follows PRISMA reporting guidelines. SETTING AND PARTICIPANTS: We examined controlled trials and intervention studies that included long-term care residents aged ≥60 years who received interventions to reduce chronic pain. Interventions were either delivered by healthcare aides at the resident level or were directed at healthcare aides to improve their pain management practices for residents. METHODS: We searched 7 databases to identify relevant studies. After screening 400 articles, we reviewed 131 full-text articles and included them if they reported a pain management intervention and measured pain with a standardized pain scale. Data were synthesized narratively. Risk of bias was assessed using the Mixed Methods Assessment Tool. RESULTS: In total, 9 studies were examined in the narrative review. Six studies described pain interventions involving education, new pain protocols and/or new assessment tools delivered to healthcare aides. Three studies described pain interventions delivered by healthcare aides to residents, which included a new incontinence care routine, light touch massage, and a bathing intervention. CONCLUSIONS AND IMPLICATIONS: Interventions involving healthcare aides may be beneficial to pain management for long-term care residents as they have the potential to reduce residents' pain and improve both pain assessment and reporting practices. Further research is warranted on specific elements that contribute to an improvement in residents' pain and to the overall role of healthcare aides care of residents.

Influences of post-implementation factors on the sustainability, sustainment, and intra-organizational spread of complex interventions.

BACKGROUND: Complex interventions are increasingly applied to healthcare problems. Understanding of post-implementation sustainment, sustainability, and spread of interventions is limited. We examine these phenomena for a complex quality improvement initiative led by care aides in 7 care homes (long-term care homes) in Manitoba, Canada. We report on factors influencing these phenomena two years after implementation. METHODS: Data were collected in 2019 via small group interviews with unit- and care home-level managers (n = 11) from 6 of the 7 homes using the intervention. Interview participants discussed post-implementation factors that influenced continuing or abandoning core intervention elements (processes, behaviors) and key intervention benefits (outcomes, impact). Interviews were audio-recorded, transcribed verbatim, and analyzed with thematic analysis. RESULTS: Sustainment of core elements and sustainability of key benefits were observed in 5 of the 6 participating care homes. Intra-unit intervention spread occurred in 3 of 6 homes. Factors influencing sustainment, sustainability, and spread related to intervention teams, unit and care home, and the long-term care system. CONCLUSIONS: Our findings contribute understanding on the importance of micro-, meso-, and macro-level factors to sustainability of key benefits and sustainment of some core processes. Inter-unit spread relates exclusively to meso-level factors of observability and practice change institutionalization. Interventions should be developed with post-implementation sustainability in mind and measures taken to protect against influences such as workforce instability and competing internal and external demands. Design should anticipate need to adapt interventions to strengthen post-implementation traction.

Management of Chronic Pain in Long-Term Care: A Systematic Review and Meta-Analysis.

OBJECTIVES: Pain, a complex subjective experience, is common in care home residents. Despite advances in pain management, optimal pain control remains a challenge. In this updated systematic review, we examined effectiveness of interventions for treating chronic pain in care home residents. DESIGN: A Cochrane-style systematic review and meta-analysis using PRISMA guidelines. SETTING AND PARTICIPANTS: Randomized and nonrandomized controlled trials and intervention studies included care home residents aged ≥60 years receiving interventions to reduce chronic pain. METHODS: Six databases were searched to identify relevant studies. After duplicate removal, articles were screened by title and abstract. Full-text articles were reviewed and included if they implemented a pain management intervention and measured pain with a standardized quantitative pain scale. Meta-analyses calculated standardized mean differences (SMDs) using random-effect models. Risk of bias was assessed using the Cochrane Risk-of-Bias Tool 2.0. RESULTS: We included 42 trials in the meta-analysis and described 13 more studies narratively. Studies included 26 nondrug alternative treatments, 8 education interventions, 7 system modifications, 3 nonanalgesic drug treatments, 2 analgesic treatments, and 9 combined interventions. Pooled results at trial completion revealed that, except for nonanalgesic drugs and health system modification interventions, all interventions were at least moderately effective in reducing pain. Analgesic treatments (SMD -0.80; 95% CI -1.47 to -0.12; P = .02) showed the greatest treatment effect, followed by nondrug alternative treatments (SMD -0.70; 95% CI -0.95 to -0.45; P < .001), combined interventions (SMD -0.37; 95% CI -0.60 to -0.13; P = .002), and education interventions (SMD -0.31; 95% CI -0.48 to -0.15; P < .001). CONCLUSIONS AND IMPLICATIONS: Our findings suggest that analgesic drugs and nondrug alternative pain management strategies are the most effective in reducing pain among care home residents. Clinicians should also consider implementing nondrug alternative therapies in care homes, rather than relying solely on analgesic drug options.

SCOPE: safer care for older persons (in residential) environments-a pilot study to enhance care aide-led quality improvement in nursing homes.

BACKGROUND: Nursing home residents require daily support. While care aides provide most of this support they are rarely empowered to lead quality improvement (QI) initiatives. Researchers have shown that care aide-led teams can successfully participate in a QI intervention called Safer Care for Older Persons in Residential Care Environments (SCOPE). In preparation for a large-scale study, we conducted a 1-year pilot to evaluate how well coaching strategies helped teams to enact this intervention. Secondarily, we measured if improvements in team cohesion and communication, and resident quality of care, occurred. METHODS: This study was conducted using a prospective single-arm study design, on 7 nursing homes in Winnipeg Manitoba belonging to the Translating Research in Elder Care research program. One QI team was selected per site, led by care aides who partnered with other front-line staff. Each team received facilitated coaching to enact SCOPE during three learning sessions, and additional support from quality advisors between these sessions. Researchers developed a rubric to evaluate how well teams enacted their interventions (i.e., created actionable aim statements, implemented interventions using plan-do-study-act cycles, and used measurement to guide decision-making). Team cohesion and communication were measured using surveys, and changes in unit-level quality indicators were measured using Resident Assessment Instrument-Minimum Data Set data. RESULTS: Most teams successfully enacted their interventions. Five of 7 teams created adequate-to-excellent aim statements. While 6 of 7 teams successfully implemented plan-do-study-act cycles, only 2 reported spreading their change ideas to other residents and staff on their unit. Three of 7 teams explicitly stated how measurement was used to guide intervention decisions. Teams scored high in cohesion and communication at baseline, and hence improved minimally. Indicators of resident quality care improved in 4 nursing home units; teams at 3 of these sites were scored as 'excellent' in two or more enactment areas, versus 1 of the 3 remaining teams. CONCLUSIONS: Our coaching strategies helped most care aide-led teams to enact SCOPE. Coaching modifications are needed to help teams more effectively use measurement. Refinements to our evaluation rubric are also recommended.

Sustainment, Sustainability, and Spread Study (SSaSSy): protocol for a study of factors that contribute to the sustainment, sustainability, and spread of practice changes introduced through an evidence-based quality-improvement intervention in Canadian nursing homes.

BACKGROUND: Implementation scientists and practitioners, alike, recognize the importance of sustaining practice change, however post-implementation studies of interventions are rare. This is a protocol for the Sustainment, Sustainability and Spread Study (SSaSSy). The purpose of this study is to contribute to knowledge on the sustainment (sustained use), sustainability (sustained benefits), and spread of evidence-based practice innovations in health care. Specifically, this is a post-implementation study of an evidence-informed, Care Aide-led, facilitation-based quality-improvement intervention called SCOPE (Safer Care for Older Persons (in long-term care) Environments). SCOPE has been implemented in nursing homes in the Canadian Provinces of Manitoba (MB), Alberta (AB) and British Columbia (BC). Our study has three aims: (i) to determine the role that adaptation/contextualization plays in sustainment, sustainability and spread of the SCOPE intervention; (ii) to study the relative effects on sustainment, sustainability and intra-organizational spread of high-intensity and low-intensity post-implementation "boosters", and a "no booster" condition, and (iii) to compare the relative costs and impacts of each booster condition. METHODS/DESIGN: SSaSSy is a two-phase mixed methods study. The overarching design is convergent, with qualitative and quantitative data collected over a similar timeframe in each of the two phases, analyzed independently, then merged for analysis and interpretation. Phase 1 is a pilot involving up to 7 units in 7 MB nursing homes in which SCOPE was piloted in 2016 to 2017, in preparation for phase 2. Phase 2 will comprise a quasi-experiment with two treatment groups of low- and high-intensity post-implementation "boosters", and an untreated control group (no booster), using pretests and post-tests of the dependent variables relating to sustained care and management practices, and resident outcomes. Phase 2 will involve 31 trial sites in BC (17 units) and AB (14 units) nursing homes, where the SCOPE trial concluded in May 2019. DISCUSSION: This project stands to advance understanding of the factors that influence the sustainment of practice changes introduced through evidence-informed practice change interventions, and their associated sustainability. Findings will inform our understanding of the nature of the relationship of fidelity and adaptation to sustainment and sustainability, and afford insights into factors that influence the intra-organizational spread of practice changes introduced through complex interventions.

Depressive symptoms in long term care facilities in Western Canada: a cross sectional study.

BACKGROUND: The main objective is to better understand the prevalence of depressive symptoms, in long-term care (LTC) residents with or without cognitive impairment across Western Canada. Secondary objectives are to examine comorbidities and other factors associated with of depressive symptoms, and treatments used in LTC. METHODS: 11,445 residents across a random sample of 91 LTC facilities, from 09/2014 to 05/2015, were stratified by owner-operator model (private for-profit, public or voluntary not-for-profit), size (small: < 80 beds, medium: 80-120 beds, large > 120 beds), location (Calgary and Edmonton Health Zones, Alberta; Fraser and Interior Health Regions, British Columbia; Winnipeg Health Region, Manitoba). Random intercept generalized linear mixed models with depressive symptoms as the dependent variable, cognitive impairment as primary independent variable, and resident, care unit and facility characteristics as covariates were used. Resident variables came from the Resident Assessment Instrument - Minimum Data Set (RAI-MDS) 2.0 records (the RAI-MDS version routinely collected in Western Canadian LTC). Care unit and facility variables came from surveys completed with care unit or facility managers. RESULTS: Depressive symptoms affects 27.1% of all LTC residents and 23.3% of LTC resident have both, depressive symptoms and cognitive impairment. Hypertension, urinary and fecal incontinence were the most common comorbidities. Cognitive impairment increases the risk for depressive symptoms (adjusted odds ratio 1.65 [95% confidence interval 1.43; 1.90]). Pain, anxiety and pulmonary disorders were also significantly associated with depressive symptoms. Pharmacologic therapies were commonly used in those with depressive symptoms, however there was minimal use of non-pharmacologic management. CONCLUSIONS: Depressive symptoms are common in LTC residents -particularly in those with cognitive impairment. Depressive symptoms are an important target for clinical intervention and further research to reduce the burden of these illnesses.

Pain Assessment for Nursing Home Residents: A Systematic Review Protocol.

BACKGROUND: The burden of pain in nursing homes is substantial; however, pain assessment for both acute and chronic conditions remains inadequate, resulting in inappropriate or inadequate treatment. Complexities in assessing resident pain have been attributed to factors (barriers and facilitators) arising at the resident, healthcare provider, and healthcare system levels. OBJECTIVES: In this systematic review protocol, we identify our research approach that will be used to critically appraise and synthesize data in order to assess barriers and facilitators to pain assessment in nursing home residents aged ≥65 years. METHODS: This is a Cochrane style systematic review protocol adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Protocols reporting standards. This review will include primary (original) qualitative literature concerning either barriers or facilitators to pain assessment in older adult nursing home residents. A thematic analysis approach will be employed in collating and summarizing included data and will be categorized into resident, healthcare provider, and system-level factors. Database searches will include Abstracts in Social Gerontology, CINAHL, Cochrane Central Register of Controlled Trials, Embase, MEDLINE, and Web of Science. DISCUSSION: The identification of barriers and facilitators to pain assessment in older adult nursing home residents may assist healthcare providers across all platforms and levels of education to improve pain assessment among nursing home residents. Improving the assessment of pain has the potential to improve quality of care and ultimately quality of life for older adult nursing home residents.

Nursing Home Length of Stay in 3 Canadian Health Regions: Temporal Trends, Jurisdictional Differences, and Associated Factors.

OBJECTIVES: To assess (1) temporal changes (2008-2015) in nursing home (NH) length of stay (LoS) in 3 Canadian health jurisdictions (Edmonton, Calgary, Winnipeg), (2) resident admission characteristics associated with LoS, and (3) temporal changes of admission characteristics in each of the 3 jurisdictions. DESIGN: Retrospective cohort study using data previously collected in Translating Research in Elder Care (TREC), a longitudinal program of applied health services research in Canadian NHs. SETTING AND PARTICIPANTS: 7817 residents admitted between January 2008 and December 2015 to a stable cohort of 18 NHs that have consistently participated in TREC since 2007. METHODS: LoS was defined as time between a resident's first NH admission and final discharge from the NH sector. Analyses included descriptive statistics, Kaplan Meier estimates (unadjusted LoS), and Cox proportional hazard regressions (adjusted LoS), adjusted for resident characteristics (eg, age, cognitive performance, and health instability). We also controlled for NH size and ownership. RESULTS: In jurisdictions with increasing care needs, unadjusted median LoS [95% confidence interval (CI)] decreased over time (2008 and 2009 vs 2014 and 2015 admissions); in Calgary from 1.837 (95% CI 1.618, 2.275) to 1.328 (95% CI 1.185, 1.489) years and in Edmonton from 1.927 (95% CI 1.725, 2.188) to 1.073 (95% CI 0.936, 1.248) years. In Winnipeg, care needs and LoS remained constant (2.163, 95% CI 1.867, 2.494, vs 2.459, 95% CI 2.155, 2.883, years). Resident characteristics including higher physical dependency [hazard ratio (HR) 1.205, 95% CI 1.133, 1.282], higher cognitive impairment (HR 1.112, 95% CI 1.042, 1.187), or higher health instability (HR 1.333, 95% CI 1.224, 1.452) were associated with lower LoS. Adjustment for resident characteristics reduced jurisdictional LoS differences and rendered temporal LoS differences within jurisdictions statistically nonsignificant. CONCLUSIONS/IMPLICATIONS: In jurisdictions where care needs at admission have increased since 2008, resident LoS has decreased. Jurisdictional differences in care needs and LoS indicate that health policies may affect these outcomes. Variations of resident outcomes by policy environment require additional scrutiny.

Factors Associated With Pain Assessment for Nursing Home Residents: A Systematic Review and Meta-Synthesis.

OBJECTIVES: The burden of pain in nursing home residents is substantial; unfortunately, many times it goes undiagnosed and is inadequately treated. To improve identification of pain in this population, we aimed to review and synthesize findings from qualitative studies that report primary barriers and facilitators to pain assessment in nursing home residents. DESIGN: This is a Cochrane-style systematic review and narrative synthesis of qualitative evidence adhering to PRISMA guidelines. Databases were searched from inception to June 2018, supplemented by hand searching of references. We assessed the quality of included studies using the Critical Appraisal Skills Program Quality Appraisal Checklist. SETTING AND PARTICIPANTS: We included studies conducted in nursing homes. Studies focused on nursing home residents, nursing home staff, or both. MEASURES: Extracted data were subject to thematic analyses and were collated and summarized into 3 groups: resident, health care provider, and health care system factors. RESULTS: Thirty-one studies met our inclusion criteria. Resident factors had 3 subthemes: physical or cognitive impairments, attitudes and beliefs, and social/cultural/demographic characteristics. Health care provider factors had 3 subthemes: knowledge and skills, attitudes and beliefs, and social/cultural/demographic characteristics. Health care system-level factors had 3 subthemes: interpersonal factors, resources, and policy. Key barriers to pain assessment included the presence of resident cognitive impairment, health care providers' lack of knowledge, and the breakdown of communication across organizational hierarchies. Key facilitators to pain assessment included the identification of pain-related behaviors in residents, the experience and skills of health care providers, and establishing facility-level pain assessment protocols and guidelines. CONCLUSION AND IMPLICATIONS: Findings from this review identify primary barriers and facilitators to pain assessment in nursing home residents, highlighting key considerations for stakeholders, including health care providers, and health care policy decision makers. These efforts have the potential to improve the identification of pain in residents, and may ultimately improve pain management and residents' quality of life.

Implementing Frontline Worker-Led Quality Improvement in Nursing Homes: Getting to "How".

BACKGROUND: Despite emerging frameworks for quality improvement (QI) implementation, little is known about how the implementation process works, particularly in nursing home settings. A study was conducted to describe "how"' a complex frontline worker-led QI program was implemented in nursing homes. METHODS: Six focus groups were conducted in February 2017 with participants of a year-long, multicomponent, unit-level QI intervention in seven nursing homes in the Canadian province of Manitoba. Constant comparative analysis was used to examine perspectives of different groups of QI program participants-35 health care aides, health professionals, and managers. RESULTS: Five themes important to the implementation process were identified: (1) "supportive elements of the QI program structure," (2) "navigating the workplace," (3) "negotiating relationships," (4) "developing individual skills," and (5) "observable program impact." Data on theme integration suggest that "supportive elements of the QI program structure" (Theme 1), "developing individual skills" (Theme 4), and "observable program impact" (on residents, health care aides, and leaders; Theme 5) operated as part of a reinforcing feedback loop that boosted team members' ability to navigate the workplace, negotiate relationships, and implement the QI program. CONCLUSION: Health care aide-led QI teams are feasible. However, a leadership paradox exists whereby worker-led QI programs also must incorporate concrete mechanisms to promote strong leadership and sponsor support to teams. The findings also point to the underexplored impact of interpersonal relationships between health care aides and professional staff on QI implementation.

Health of health care workers in Canadian nursing homes and pediatric hospitals: a cross-sectional study.

BACKGROUND: Poor health of health care workers affects quality of care, but research and health data for health care workers are scarce. Our aim was to compare physical/mental health among health care worker groups 1) within nursing homes and pediatric hospitals, 2) between the 2 settings and 3) with the physical/mental health of the Canadian population. METHODS: Using cross-sectional data collected as part of the Translating Research in Elder Care program and the Translating Research on Pain in Children program, we examined the health of health care workers. In nursing homes, 169 registered nurses, 139 licensed practical nurses, 1506 care aides, 145 allied health care providers and 69 managers were surveyed. In pediatric hospitals, 63 physicians, 747 registered nurses, 155 allied health care providers, 49 nurse educators and 22 managers were surveyed. After standardization of the data for age and sex, we applied analyses of variance and general linear models, adjusted for multiple testing. RESULTS: Nursing home workers and registered nurses in pediatric hospitals had poorer mental health than the Canadian population. Scores were lowest for registered nurses in nursing homes (mean difference -4.4 [95% confidence interval -6.6 to -2.6]). Physicians in pediatric hospitals and allied health care providers in nursing homes had better physical health than the general population. We also found important differences in physical/mental health for care provider groups within and between care settings. INTERPRETATION: Mental health is especially poor among nursing home workers, who care for a highly vulnerable and medically complex population of older adults. Strategies including optimized work environments are needed to improve the physical and mental health of health care workers to ameliorate quality of patient care.

Inhaled magnesium sulfate in the treatment of acute asthma.

BACKGROUND: Asthma exacerbations can be frequent and range in severity from mild to life-threatening. The use of magnesium sulfate (MgSO4) is one of numerous treatment options available during acute exacerbations. While the efficacy of intravenous MgSO4 has been demonstrated, the role of inhaled MgSO4 is less clear. OBJECTIVES: To determine the efficacy and safety of inhaled MgSO4 administered in acute asthma. SPECIFIC AIMS: to quantify the effects of inhaled MgSO4 I) in addition to combination treatment with inhaled ß2-agonist and ipratropium bromide; ii) in addition to inhaled ß2-agonist; and iii) in comparison to inhaled ß2-agonist. SEARCH METHODS: We identified randomised controlled trials (RCTs) from the Cochrane Airways Group register of trials and online trials registries in September 2017. We supplemented these with searches of the reference lists of published studies and by contact with trialists. SELECTION CRITERIA: RCTs including adults or children with acute asthma were eligible for inclusion in the review. We included studies if patients were treated with nebulised MgSO4 alone or in combination with ß2-agonist or ipratropium bromide or both, and were compared with the same co-intervention alone or inactive control. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial selection, data extraction and risk of bias. We made efforts to collect missing data from authors. We present results, with their 95% confidence intervals (CIs), as mean differences (MDs) or standardised mean differences (SMDs) for pulmonary function, clinical severity scores and vital signs; and risk ratios (RRs) for hospital admission. We used risk differences (RDs) to analyse adverse events because events were rare. MAIN RESULTS: Twenty-five trials (43 references) of varying methodological quality were eligible; they included 2907 randomised patients (2777 patients completed). Nine of the 25 included studies involved adults; four included adult and paediatric patients; eight studies enrolled paediatric patients; and in the remaining four studies the age of participants was not stated. The design, definitions, intervention and outcomes were different in all 25 studies; this heterogeneity made direct comparisons difficult. The quality of the evidence presented ranged from high to very low, with most outcomes graded as low or very low. This was largely due to concerns about the methodological quality of the included studies and imprecision in the pooled effect estimates. Inhaled magnesium sulfate in addition to inhaled ß2-agonist and ipratropiumWe included seven studies in this comparison. Although some individual studies reported improvement in lung function indices favouring the intervention group, results were inconsistent overall and the largest study reporting this outcome found no between-group difference at 60 minutes (MD -0.3 % predicted peak expiratory flow rate (PEFR), 95% CI -2.71% to 2.11%). Admissions to hospital at initial presentation may be reduced by the addition of inhaled magnesium sulfate (RR 0.95, 95% CI 0.91 to 1.00; participants = 1308; studies = 4; I² = 52%) but no difference was detected for re-admissions or escalation of care to ITU/HDU. Serious adverse events during admission were rare. There was no difference between groups for all adverse events during admission (RD 0.01, 95% CI -0.03 to 0.05; participants = 1197; studies = 2). Inhaled magnesium sulfate in addition to inhaled ß2-agonistWe included 13 studies in this comparison. Although some individual studies reported improvement in lung function indices favouring the intervention group, none of the pooled results showed a conclusive benefit as measured by FEV1 or PEFR. Pooled results for hospital admission showed a point estimate that favoured the combination of MgSO4 and ß2-agonist, but the confidence interval includes the possibility of admissions increasing in the intervention group (RR 0.78, 95% CI 0.52 to 1.15; participants = 375; studies = 6; I² = 0%). There were no serious adverse events reported by any of the included studies and no between-group difference for all adverse events (RD -0.01, 95% CI -0.05 to 0.03; participants = 694; studies = 5). Inhaled magnesium sulfate versus inhaled ß2-agonistWe included four studies in this comparison. The evidence for the efficacy of ß2-agonists in acute asthma is well-established and therefore this could be considered a historical comparison. Two studies reported a benefit of ß2-agonist over MgSO4 alone for PEFR and two studies reported no difference; we did not pool these results. Admissions to hospital were only reported by one small study and events were rare, leading to an uncertain result. No serious adverse events were reported in any of the studies in this comparison; one small study reported mild to moderate adverse events but the result is imprecise. AUTHORS' CONCLUSIONS: Treatment with nebulised MgSO4 may result in modest additional benefits for lung function and hospital admission when added to inhaled ß2-agonists and ipratropium bromide, but our confidence in the evidence is low and there remains substantial uncertainty. The recent large, well-designed trials have generally not demonstrated clinically important benefits. Nebulised MgSO4 does not appear to be associated with an increase in serious adverse events. Individual studies suggest that those with more severe attacks and attacks of shorter duration may experience a greater benefit but further research into subgroups is warranted.Despite including 24 trials in this review update we were unable to pool data for all outcomes of interest and this has limited the strength of the conclusions reached. A core outcomes set for studies in acute asthma is needed. This is particularly important in paediatric studies where measuring lung function at the time of an exacerbation may not be possible. Placebo-controlled trials in patients not responding to standard maximal treatment, including inhaled ß2-agonists and ipratropium bromide and systemic steroids, may help establish if nebulised MgSO4 has a role in acute asthma. However, the accumulating evidence suggests that a substantial benefit may be unlikely.

Nurses' knowledge and perception of delirium screening and assessment in the intensive care unit: Long-term effectiveness of an education-based knowledge translation intervention.

OBJECTIVES: To determine the impact of education on nurses' knowledge of delirium, knowledge and perception of a validated screening tool, and delirium screening in the ICU. METHODS: A quasi-experimental single group pretest-post-test design. SETTING: A 16 bed ICU in a Canadian urban tertiary care centre. MAIN OUTCOME MEASURES: Nursing knowledge and perception were measured at baseline, 3-month and 18-month periods. Delirium screening was then assessed over 24-months. RESULTS: During the study period, 197 surveys were returned; 84 at baseline, 53 at 3-months post education, and 60 at the final assessment period 18-months post intervention. The significant improvements in mean knowledge scores at 3-months post intervention (7.2, SD 1.3) were not maintained at 18-months (5.3, SD 1.1). Screening tool perception scores remained unchanged. Improvements in the perception of utility were significant at both time periods (p=0.03, 0.02 respectively). Physician value significantly improved at 18-months (p=0.01). Delirium screening frequency improved after education (p<0.001) demonstrating a positive correlation over time (p<0.01). CONCLUSION: Multifaceted education is effective in improving delirium knowledge and screening; however, without sustained effort, progress is transient. Education improved perceived tool utility and over time utility perception and physician value improved.

Pathways for best practice diffusion: the structure of informal relationships in Canada's long-term care sector.

BACKGROUND: Initiatives to accelerate the adoption and implementation of evidence-based practices benefit from an association with influential individuals and organizations. When opinion leaders advocate or adopt a best practice, others adopt too, resulting in diffusion. We sought to identify existing influence throughout Canada's long-term care sector and the extent to which informal advice-seeking relationships tie the sector together as a network. METHODS: We conducted a sociometric survey of senior leaders in 958 long-term care facilities operating in 11 of Canada's 13 provinces and territories. We used an integrated knowledge translation approach to involve knowledge users in planning and administering the survey and in analyzing and interpreting the results. Responses from 482 senior leaders generated the names of 794 individuals and 587 organizations as sources of advice for improving resident care in long-term care facilities. RESULTS: A single advice-seeking network appears to span the nation. Proximity exhibits a strong effect on network structure, with provincial inter-organizational networks having more connections and thus a denser structure than interpersonal networks. We found credible individuals and organizations within groups (opinion leaders and opinion-leading organizations) and individuals and organizations that function as weak ties across groups (boundary spanners and bridges) for all studied provinces and territories. A good deal of influence in the Canadian long-term care sector rests with professionals such as provincial health administrators not employed in long-term care facilities. CONCLUSIONS: The Canadian long-term care sector is tied together through informal advice-seeking relationships that have given rise to an emergent network structure. Knowledge of this structure and engagement with its opinion leaders and boundary spanners may provide a route for stimulating the adoption and effective implementation of best practices, improving resident care and strengthening the long-term care advice network. We conclude that informal relational pathways hold promise for helping to transform the Canadian long-term care sector.
