A scoping review of resilience among transition-age youth with serious mental illness: tensions, knowledge gaps, and future directions.

INTRODUCTION: The study of resilience among transition-age youth (aged 16-29 years) living with serious mental illness (SMI) has provided a promising new direction for research with the capacity to explore individuals' strengths and resources. However, variability in how resilience is defined and measured has led to a lack of conceptual clarity. A comprehensive synthesis is needed to understand current trends and gaps in resilience research among this population. The purpose of the current study was to map how resilience has been conceptualized and operationalized among transition-age youth with SMI, explore resilience factors and outcomes that have been studied, and recommend areas for future research. METHODS: A six-stage scoping review methodology was used to systematically identify relevant empirical literature across multiple databases (MEDLINE, EMBASE, PsycINFO, AMED, CINAHL, Scopus), addressing transition-age youth diagnosed with SMI and resilience. Topic consultation and reaction meetings were conducted to gather feedback from transition-age youth with SMI, researchers, and clinicians during the review process to enhance the applicability of the review findings. A meta-narrative approach was used to organize included studies into research traditions (i.e., paradigms of inquiry with similar storylines, theoretical and methodological orientations). Resilience factors and outcomes, and the consultative meetings, were analyzed using content analysis. RESULTS: Twenty-four studies met inclusion criteria (14 quantitative, 9 qualitative, 1 mixed-method). Four research traditions were identified, each contributing a unique storyline which conceptualized and operationalized resilience in slightly different ways: Stress Adaptation, Person-Environment Interactions, Recovery-Focused, and Critical and Cultural Perspectives. Resilience factors and outcomes were most commonly evaluated at the individual-level or within the immediate environment (e.g., personal characteristics, social support networks). Limited research has explored the influence of macro-level systems and health inequalities on resilience processes. Results from the consultative meetings further demonstrated the importance of health services and sociocultural factors in shaping processes of resilience among youth. CONCLUSION: The present results may be used to inform future work, as well as the development of age-appropriate, strengths-based, and resilience-oriented approaches to service delivery. Interdisciplinary and intersectional research that prioritizes community and youth engagement is needed to advance current understandings of resilience among transition-age youth with SMI.

Rapid Agitation Control With Ketamine in the Emergency Department: A Blinded, Randomized Controlled Trial.

STUDY OBJECTIVE: We hypothesized that the use of intramuscular ketamine would result in a clinically relevant shorter time to target sedation. METHODS: We conducted a randomized clinical trial comparing the rapidity of onset, level of sedation, and adverse effect profile of ketamine compared to a combination of midazolam and haloperidol for behavioral control of emergency department patients with severe psychomotor agitation. We included patients with severe psychomotor agitation measured by a Richmond Agitation Score (RASS) ≥+3. Patients in the ketamine group were treated with a 5 mg/kg intramuscular injection. Patients in the midazolam and haloperidol group were treated with a single intramuscular injection of 5 mg midazolam and 5 mg haloperidol. The primary outcome was the time, in minutes, from study medication administration to adequate sedation, defined as RASS ≤-1. Secondary outcomes included the need for rescue medications and serious adverse events. RESULTS: Between June 30, 2018, and March 13, 2020, we screened 308 patients and enrolled 80. The median time to sedation was 14.7 minutes for midazolam and haloperidol versus 5.8 minutes for ketamine (difference 8.8 minutes [95% confidence interval (CI) 3.0 to 14.5]). Adjusted Cox proportional model analysis favored the ketamine arm (hazard ratio 2.43, 95% CI 1.43 to 4.12). Five (12.5%) patients in the ketamine arm and 2 (5.0%) patients in the midazolam and haloperidol arm experienced serious adverse events (difference 7.5% [95% CI -4.8% to 19.8%]). CONCLUSION: In ED patients with severe agitation, intramuscular ketamine provided significantly shorter time to adequate sedation than a combination of intramuscular midazolam and haloperidol.

Emerging Guidelines for Patient Engagement in Research.

There is growing recognition that involving patients in the development of new patient-reported outcome measures helps ensure that the outcomes that matter most to people living with health conditions are captured. Here, we describe and discuss different experiences of integrating patients as full patient research partners (PRPs) in outcomes research from multiple perspectives (e.g., researcher, patient, and funder), drawing from three real-world examples. These diverse experiences highlight the strengths, challenges, and impact of partnering with patients to conceptualize, design, and conduct research and disseminate findings. On the basis of our experiences, we suggest basic guidelines for outcomes researchers on establishing research partnerships with patients, including: 1) establishing supportive organizational/institutional policies; 2) cultivating supportive attitudes of researchers and PRPs with recognition that partnerships evolve over time, are grounded in strong communication, and have shared goals; 3) adhering to principles of respect, trust, reciprocity, and co-learning; 4) addressing training needs of all team members to ensure communications and that PRPs are conversant in and familiar with the language and process of research; 5) identifying the resources and advanced planning required for successful patient engagement; and 6) recognizing the value of partnerships across all stages of research. The three experiences presented explore different approaches to partnering; demonstrate how this can fundamentally change the way research work is conceptualized, conducted, and disseminated; and can serve as exemplars for other forms of patient-centered outcomes research. Further work is needed to identify the skills, qualities, and approaches that best support effective patient-researcher partnerships.

Preliminary validation of the Claudication Symptom Instrument (CSI).

This article describes the development of the Claudication Symptom Instrument (CSI) and its measurement properties for evaluating the symptom experience of patients diagnosed with intermittent claudication (IC). We conducted semi-structured qualitative interviews with IC patients for item development and cognitive interviews in which patient comprehension of items was tested. We evaluated measurement properties using data collected and analyzed in the context of an observational comparative effectiveness study of IC treatments. Items measuring five symptom important to patients were developed and cognitively tested: Pain, Numbness, Heaviness, Cramping, and Tingling. Item means (higher means worse) ranged from 1.1 (Tingling) to 2.3 (Pain) (range: 0 'none' to 4 'extreme'). Rasch analysis yielded support for an overall score (χ2=26.5, df=20, p=0.15). The total CSI score differed by clinician-rated severity of mild versus moderate ( p<0.05), but not moderate versus severe. Re-administration of the CSI 5-10 days after baseline yielded an intra-class correlation coefficient of 0.86. Changes in CSI total score and VASCUQOL total score between baseline and 6 months post-treatment were correlated at -0.52 ( p<0.05). The CSI preliminarily meets accepted measurement standards for content validity, internal consistency and test-retest reliability, construct validity, and sensitivity for detecting change. Because of its high test-retest reliability, it may also be useful in clinical care with individual patients. It takes approximately 3 minutes to complete.

How have research questions and methods used in clinical trials published in Clinical Rehabilitation changed over the last 30 years?

Research in rehabilitation has grown from a rare phenomenon to a mature science and clinical trials are now common. The purpose of this study is to estimate the extent to which questions posed and methods applied in clinical trials published in Clinical Rehabilitation have evolved over three decades with respect to accepted standards of scientific rigour. Studies were identified by journal, database, and hand searching for the years 1986 to 2016.A total of 390 articles whose titles suggested a clinical trial of an intervention, with or without randomization to form groups, were reviewed. Questions often still focused on methods to be used (57%) rather than what knowledge was to be gained. Less than half (43%) of the studies delineated between primary and secondary outcomes; multiple outcomes were common; and sample sizes were relatively small (mean 83, range 5 to 3312). Blinding of assessors was common (72%); blinding of study subjects was rare (19%). In less than one-third of studies was intention-to-treat analysis done correctly; power was reported in 43%. There is evidence of publication bias as 83% of studies reported either a between-group or a within-group effect. Over time, there was an increase in the use of parameter estimation rather than hypothesis testing and there was evidence that methodological rigour improved.Rehabilitation trialists are answering important questions about their interventions. Outcomes need to be more patient-centred and a measurement framework needs to be explicit. More advanced statistical methods are needed as interventions are complex. Suggestions for moving forward over the next decades are given.

Emotional vitality in caregivers: application of Rasch Measurement Theory with secondary data to development and test a new measure.

OBJECTIVE: To describe the practical steps in identifying items and evaluating scoring strategies for a new measure of emotional vitality in informal caregivers of individuals who have experienced a significant health event. DESIGN: The psychometric properties of responses to selected items from validated health-related quality of life and other psychosocial questionnaires administered four times over a one-year period were evaluated using Rasch Measurement Theory. SETTING: Community. SUBJECTS: A total of 409 individuals providing informal care at home to older adults who had experienced a recent stroke. MAIN MEASURES: Rasch Measurement Theory was used to test the ordering of response option thresholds, fit, spread of the item locations, residual correlations, person separation index, and stability across time. RESULTS: Based on a theoretical framework developed in earlier work, we identified 22 candidate items from a pool of relevant psychosocial measures available. Of these, additional evaluation resulted in 19 items that could be used to assess the five core domains. The overall model fit was reasonable (χ(2) = 202.26, DF = 117, p = 0.06), stable across time, with borderline evidence of multidimensionality (10%). Items and people covered a continuum ranging from -3.7 to +2.7 logits, reflecting coverage of the measurement continuum, with a person separation index of 0.85. Mean fit of caregivers was lower than expected (-1.31 ±1.10 logits). CONCLUSION: Established methods from the Rasch Measurement Theory were applied to develop a prototype measure of emotional vitality that is acceptable, reliable, and can be used to obtain an interval level score for use in future research and clinical settings.

Emotional vitality in family caregivers: content validation of a theoretical framework.

PURPOSE: Emotional vitality may play an important role in determining whether informal caregivers are able to successfully adopt and persist in their roles. This study describes a content validation of a conceptual model of emotional vitality in informal caregivers. METHODS: A secondary content analysis was performed on transcripts of 30 caregivers who were interviewed about their quality of life in relation to assuming the role of informal caregiver for a family member who had experienced a recent stroke. Caregivers discussed changes in their own health, relationships, roles, finances, participation, and mood after assuming the caregiving role. Using a thematic inductive approach, two raters independently coded the presence and frequency of physical, emotional, and social impacts associated with the caregiving role in order to further develop and validate a conceptual model of caregiver emotional vitality. RESULTS: The interviews provided information that affirmed the relevance of four themes relevant to caregiver emotional vitality previously identified: physical health and well-being; mood regulation; sense of control/mastery of new skills; and participation in meaningful activity. An additional theme of support and recognition from others also emerged. CONCLUSIONS: Adopting the informal caregiving role results in major impacts to the caregiver's physical, emotional, and social health. Five core domains appear to meaningfully contribute to emotional vitality of caregivers and may influence their ability to persist in this role over time. Many of the factors that influence emotional vitality in caregivers are potentially modifiable. This new model offers new opportunities for rehabilitation specialists and allied health professionals to develop skill-building interventions that may help caregivers successfully adapt and thrive in the caregiving role.

Emotional vitality: concept of importance for rehabilitation.

OBJECTIVES: To (1) provide a framework for the conceptualization of emotional vitality as an important construct for rehabilitation professionals; (2) outline the existing scope and breadth of knowledge currently available regarding the definition and measurement of emotional vitality in persons with chronic health conditions; and (3) identify the extent to which the components can be mapped to the International Classification of Functioning, Disability and Health (ICF). DESIGN: Activities included a scoping review of the literature, and a Delphi mapping exercise using the ICF. SETTING: Not applicable. PARTICIPANTS: Not applicable. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Not applicable. RESULTS: The results of this study suggest that emotional vitality is a complex latent construct that includes (1) physical energy and well-being, (2) regulation of mood, (3) mastery, and (4) engagement and interest in life. Existing literature supported the presence of all 4 components of the construct. The mapping exercise showed that 3 of these components could be readily mapped to the Body Function chapter of the ICF (energy, mood, mastery). CONCLUSIONS: Emotional vitality may influence both the physical and emotional adaptation to living with a chronic illness or disability and should be included in both assessment and treatment planning to optimize rehabilitation outcomes. Future research is needed to refine the definition and identify optimal methods of measuring this construct.

Rasch analysis of the beck depression inventory in a homeless and precariously housed sample.

The approach to analysis of and interpretation of findings from the Beck Depression Inventory (BDI), a self-report questionnaire, depends on sample characteristics. To extend work using conventional BDI scoring, the BDI's suitability in assessing symptom severity in a homeless and precariously housed sample was examined using Rasch analysis. Participants (n=478) recruited from an impoverished neighbourhood in Vancouver, Canada, completed the BDI. Rasch analysis using the partial credit model was done, and the structural validity, unidimensionality, and reliability of the BDI were studied. A receiver operating characteristic curve determined a Rasch cut-off score consistent with clinical depression, and Rasch scores were correlated with raw scores. Good fit to the Rasch model was observed after rescoring all items and removing Item 19 (Weight Loss), and unidimensionality and reliability were satisfactory. Item 9 (Suicidal Wishes) represented the most severe symptom. Rasch-based scores detected clinical depression with moderate sensitivity and specificity, and were positively correlated with conventional scores. The BDI in a community-based sample of homeless and precariously housed adults satisfied Rasch model expectations in a 20-item format, and is suitable for assessing symptom severity. Future research on depression in similar samples may reveal more information on using specific symptoms to determine clinical significance.

Rasch Measurement Theory's contribution to the psychometric properties of a co-created measure of health and wellness for Indigenous children and youth.

OBJECTIVES: To determine how Rasch Measurement Theory (RMT) methods can be used to assess the psychometric properties of the Aaniish Naa Gegii: the Children's Health and Wellbeing Measure (ACHWM) and Qanuippit. STUDY DESIGN AND SETTING: Indigenous children aged 8-18 years, from five communities, completed the 62-item ACHWM. We applied RMT methods to ACHWM data from 401 children (mean age 13.4 ± 3.4 years; 51% male) from across Ontario to examine how well the items captured the full range (±3 logit) of the concept of interest in each domain, targeted the needs of Indigenous children, and met the criteria for unidimensional and invariant measurement. RESULTS: RMT results indicated moderate-fit overall fit (raw χ2 = 809, P < 0.001). This model was further improved by aggregating the five response categories into three categories. All four domains showed excellent overall fit to the Rasch model (P > 0.05), with items covering between -4.51 and 6.02 logit, with no gaps along the theoretical continua. CONCLUSION: This study provides evidence that a set of conceptually derived items was able to produce a measure that fits the Rasch model. These results aid our understanding of wellness by establishing the clinical meaning of the scale scores.

YESS: A feasibility study of a supported employment program for youths with mental health disorders.

Objective: In Canada, employment/education support is rarely embedded as a component of mental health service delivery. This study describes a supported education/employment program (SEP) that integrates both clinical and community mental health services. The main objectives were to estimate the feasibility of a 5-week SEP among youths aged 17-24 with mental illness and to estimate the extent to which participation in this program improved employment and mental health outcomes. Methods: This was a single cohort study. Feasibility outcomes assessed were demand, acceptability, practicality, integration, adaptation, and effectiveness. These were assessed through recruitment and retention rates, recording patterns of missing data, and examining differences between completers and non-completers. Appropriateness of the outcome measures was assessed through the strength of the association between the outcome measures at baseline. Effectiveness of the program was assessed through employment and as measured using MyLifetracker (MLT), Satisfaction with Life Scale (SWLS), and the Canadian Personal Recovery Outcome Measure (CPROM). Results: A total of 110 youths with a mean age of 20.6 (SD: 2.2) were recruited. At 5 weeks, 82 (74.5%) of participants remained in the program. Of the people who completed the program, 56.1% were women, 76.6% were in stable housing and 64.1% had depression. Approximately 60% of non-completers used two or more services and were in at-risk housing. More than 25% of participants improved on the patient-reported outcomes. Scores on these measures were moderately to highly correlated with each other. Employment rates varied and corresponded to the waves of the COVID-19 pandemic in Canada. Conclusion: Results showed that this program was feasible and there was high demand for SEP during the COVID-19 pandemic but gaining employment remained difficult. Educational or employment outcomes, measured over a short period, may not be adequate. Instead, individualized and patient-reported outcome measures may be more appropriate for SEP programs.

Pain, opioid use, depressive symptoms, and mortality in adults living in precarious housing or homelessness: a longitudinal prospective study.

ABSTRACT: Pain and related consequences could contribute to comorbid illness and premature mortality in homeless and precariously housed persons. We analyzed longitudinal data from an ongoing naturalistic prospective study of a community-based sample (n = 370) to characterize risk factors and consequences of bodily pain. The aims were to describe bodily pain and associations with symptoms and psychosocial function, investigate factors that may increase or ameliorate pain, and examine the consequences of pain for symptoms, functioning, and all-cause mortality. Bodily pain severity and impact were rated with the 36-item Short Form Health Survey Bodily Pain Scale monthly over 5 years. Mixed-effects linear regression models estimated the effects of time-invariant and time-varying risk factors for pain, verified by reverse causality and multiple imputation analysis. Regression models estimated the associations between overall person-mean pain severity and subsequent functioning and suicidal ideation, and Cox proportional hazard models assessed association with all-cause mortality. Bodily pain of at least moderate severity persisted (>3 months) in 64% of participants, exceeding rates expected in the general population. Greater pain severity was associated with depressive symptom severity and month-to-month opioid use, overlaid on enduring risk associated with age, arthritis, and posttraumatic stress disorder. The frequency of prescribed and nonprescribed opioid use had nonlinear relationships with pain: intermittent use was associated with severe pain, without reverse association or change with the overdose epidemic. Greater longitudinal mean pain severity was associated with premature mortality, poorer functioning, and suicidal ideation. Considering the relationships between pain, intermittent opioid use, and depressive symptoms could improve health care for precariously housed patients.

Protocol: A mixed methods evaluation of an IPS program to increase employment and well-being for people with long-term experience of complex barriers in Vancouver's downtown and DTES.

BACKGROUND: Employment improves mental health and well-being by providing financial security, daily structure, a sense of identity and purpose, and social engagement. However, securing and sustaining employment is exceptionally challenging for vulnerable populations who experience persistent and multiple barriers, such as mental illness, homelessness, food and housing insecurity, and marginalization. Evidence-based supported employment programs, most notably individual placement and support (IPS) are becoming a more common approach for addressing the needs of these high-risk individuals. The aim of this paper is to outline the protocol for evaluating an IPS program in Vancouver's downtown and Downtown Eastside (DTES). METHODS AND DESIGN: This prospective quasi-experimental study of persons with persistent and multiple barriers to employment will use a mixed-methods approach for evaluating a novel IPS program. The evaluation will consist of survey packages and interviews that will capture outcomes related to employment and well-being, as well as the experiential process of receiving individualized and integrated supports through the IPS program. A mixed-methods approach is appropriate for this study as quantitative data will provide an objective assessment of program impacts on employment and well-being outcomes over time, while qualitative data will provide an in-depth understanding of continued barriers and experiences. DISCUSSION: The results from this evaluation will contribute evidence within a local British Columbian (BC) context that may increase access to meaningful employment for those with long-term experience of complex barriers to employment. Further, the findings will support continued improvements, and guide decision-making around practices and policy for future implementation of IPS and employment supports across BC.

Case report: Successful induction of buprenorphine/naloxone using a microdosing schedule and assertive outreach.

BACKGROUND: The requirement for moderate withdrawal prior to initiation can be a barrier to buprenorphine/naloxone induction. CASE PRESENTATION: We aimed to use a microdosing regimen to initiate regular dosing of buprenorphine/naloxone in a high-risk patient with a history of failed initiations due, in part, to withdrawal symptoms. Using an assertive outreach model and a buprenorphine/naloxone microdosing schedule, we initiated treatment of an individual's opioid use disorder. There was a successful buprenorphine/naloxone microdosing induction as the team reached a therapeutic dose of buprenorphine/naloxone. Including the induction period, the medication was used consistently for 4 weeks. CONCLUSIONS: A microdosing schedule can be used to induce a patient onto buprenorphine/naloxone with no apparent withdrawal; gradually reducing illicit substance use. This case report builds on previous literature, highlighting ways to minimize barriers to induction of buprenorphine/naloxone, using a microdosing schedule and assertive outreach. Given the safety profile of buprenorphine and its potential to be a lifesaving intervention, a larger study of microdosing is indicated.

Health provider and service-user experiences of sensory modulation rooms in an acute inpatient psychiatry setting.

BACKGROUND: Sensory modulation rooms (SMRs) are therapeutic spaces that use sensory modulation concepts and strategies to assist service users to self-regulate and modulate arousal levels. SMRs are increasingly being explored as strength-based and person-centered adjuncts to care for people receiving inpatient psychiatry services. The aim of this study is to understand health provider and inpatient service user perceptions on the use of SMRs on acute psychiatric units. METHODS: We conducted semi-structured interviews with ten service users and nine health providers (four occupational therapists and five nurses) regarding their experiences of the SMRs located on three acute inpatient units in a large urban tertiary care hospital. We audio recorded and transcribed the focus groups and used thematic analysis to analyze the data. RESULTS: Our results suggested four common themes amongst health provider and service user experiences of sensory modulation rooms: (1) service user empowerment through self-management, (2) emotional regulation, (3) an alternative to current practices, and (4) health provider and service user education. CONCLUSION: Our study supports the ecological utility of SMRs as person-centred adjunct therapeutic space viewed positively by both service users and health providers. This understanding of SMRs is critical for future service design, research and policy aimed at improving the service user experience and care for this population. Future research is needed to validate the experience of the SMRs with other patient groups and health providers.

Understanding the mental health and recovery needs of Canadian youth with mental health disorders: a Strategy for Patient-Oriented Research (SPOR) collaboration protocol.

BACKGROUND: While considerable progress is being made to understand the health and self-management needs of youth with mental health disorders, little attention has focused on the mental health and recovery needs that the youth themselves identify-this despite a national priority to incorporate patient-oriented research into the development and assessment of mental health services. To address this gap, estimates of the extent to which existing patient-reported outcome measures (PROMs)-originally developed for use amongst adult populations-are clinically meaningful and psychometrically fit for use among youth are needed. In tandem, a recovery profile for youth can be constructed incorporating the youth perspective of the services provided within a community mental health setting. METHODS/DESIGN: This study will utilize a mixed methods design incorporating qualitative focus group interviews and cross-sectional survey. Our process will begin with the hiring of a youth peer research partner who will provide lived experience expertise through all phases of the study. We will advertise, recruit, and conduct four focus groups with youth who receive services from the Foundry Vancouver Granville located in British Columbia, Canada. In the first two focus groups, we will recruit youth aged 15-18 years (n = 10). In the second two focus groups, we will recruit young adults aged 19-24 years (n = 10). In parallel, we will conduct a cross-sectional survey of the recovery and mental health needs of youth, informed by ten widely used and validated PROM. Thematic analysis techniques will guide the identification of predominant thematic trends in the qualitative focus group data. We will use Classical and Rasch measurement methods to test and analyze the reliability and validity of selected PROM measures for youth populations. DISCUSSION: The proposed study has the potential to produce a preliminary conceptual and measurement model for understanding the mental health and recovery needs of youth with mental health disorders. This evidence will inform how youth mental health services can grow, support, and sustain the capacity for a collaborative, interdisciplinary and innovative patient-oriented research environment. Findings will also contribute much needed evidence to improve the standard of care for youth who experience mental health disorders in Canada and beyond.

Cognitive Impairment in Marginally Housed Youth: Prevalence and Risk Factors.

Objective: Homeless and marginally housed youth are particularly vulnerable members of society, and are known to experience numerous health problems, including psychiatric illness, substance use, and viral infection. Despite the presence of these risk factors for cognitive compromise, there is limited research on the cognitive functioning of homeless and marginally housed youth. The present study examines the degree and pattern of cognitive impairment and associations with key risk factors in a sample of marginally housed young adults. Method: Participants (N = 101) aged 20-29 years old were recruited from single-room occupancy hotels, and underwent cognitive, psychiatric, neurological, and serological assessments. Results: Forty percent of participants were identified as mildly cognitively impaired across multiple domains, and 16% were moderately-severely impaired. Deficits in memory and attention were most prevalent, while impairments in inhibitory control/processing speed and cognitive flexibility were also present but tended to be less severe. Developmental and historical factors (premorbid intellectual functioning, neurological soft signs, earlier exposure to and longer duration of homelessness or marginal housing), as well as current health risks (stimulant dependence and hepatitis C exposure), were associated with cognitive impairment. Conclusions: The strikingly high rate of cognitive impairment in marginally housed young adults represents a major public health concern and is likely to pose a significant barrier to treatment and rehabilitation. These results suggest that the pathway to cognitive impairment involves both developmental vulnerability and modifiable risk factors. This study highlights the need for early interventions that address cognitive impairment and risk factors in marginalized young people.

Rapid agitation control with ketamine in the emergency department (RACKED): a randomized controlled trial protocol.

BACKGROUND: The rapid control of patients presenting to the emergency department (ED) with psychomotor agitation and violent behavior is paramount for the safety of patients and ED staff. The use of intramuscular (IM) ketamine in the pre-hospital and ED settings has demonstrated promising preliminary results to provide rapid and safe behavioral control. A prospective, randomized controlled trial is required to measure the potential superiority of IM ketamine compared to current standard care (IM benzodiazepines plus antipsychotics). METHODS: This will be a parallel, prospective, randomized, controlled trial of 5 mg/kg IM ketamine compared to a combination of 5 mg IM midazolam and 5 mg IM haloperidol. The study will enroll approximately 184 patients, randomized equally to two study arms. There will be one study visit during which study medication will be administered and assessments will be completed. A follow-up safety visit will occur on day 3. The primary objective of this study is to compare IM ketamine to a combination of IM midazolam and haloperidol with regards to the time required for adequate behavioral control, in minutes, in patients presenting to the ED with psychomotor agitation and violent behavior, as measured by the Richmond Agitation-Sedation Scale (RASS). DISCUSSION: We present a novel study to determine whether ketamine is a rapid and safe option, compared to a combination of midazolam and haloperidol for the sedation of patients presenting to the ED with psychomotor agitation and violent behavior. To our knowledge, this study is the first randomized controlled trial to compare ketamine to current standard care for this indication. We have attempted to address numerous logistical issues with the design of this study including a waiver of consent, ensuring adequate blinding of outcome assessors, patient enrolment, and data monitoring. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03375671 . Registered on 18 December 2017.

Clinical and functional characteristics of young adults living in single room occupancy housing: preliminary findings from a 10-year longitudinal study.

OBJECTIVE: Young adults living in single room occupancy (SRO) hotels, a form of low-income housing, are known to have complex health and substance problems compared to their peers in the general population. The objective of this study is to comprehensively describe the mental, physical, and social health profile of young adults living in SROs. METHODS: This study reports baseline data from young adults aged 18-29 years, as part of a prospective cohort study of adults living in SROs in Vancouver, British Columbia, Canada. Baseline and follow-up data were collected from 101 young adults (median follow-up period 1.9 years [IQR 1.0-3.1]). The comprehensive assessment included laboratory tests, neuroimaging, and clinician- and patient-reported measures of mental, physical, and social health and functioning. RESULTS: Three youth died during the preliminary follow-up period, translating into a higher than average mortality rate (18.6, 95% CI 6.0, 57.2) compared to age- and sex-matched Canadians. High prevalence of interactions with the health, social, and justice systems was reported. Participants were living with median two co-occurring illnesses, including mental, neurological, and infectious diseases. Greater number of multimorbid illnesses was associated with poorer real-world functioning (ρ = - 0.373, p < 0.001). All participants reported lifetime alcohol and cannabis use, with pervasive use of stimulants and opioids. CONCLUSION: This study reports high mortality rates, multimorbid illnesses, poor functioning, poverty, and ongoing unmet mental health needs among young adults living in SROs. Frequent interactions with the health, social, and justice systems suggest important points of intervention to improve health and functional trajectories of this vulnerable population.
