Diagnostic accuracy of the Ottawa 3DY and Short Blessed Test to detect cognitive dysfunction in geriatric patients presenting to the emergency department

ObjectivesCognitive dysfunction (CD) is a common finding in geriatric patients presenting to the emergency department (ED). Our primary objective was to determine the diagnostic accuracy of the Ottawa 3DY (O3DY) and Short Blessed Test (SBT) as screening tools for the detection of CD in the ED. Our secondary objective was to estimate the inter-rater reliability of these instruments.MethodsWe conducted a prospective cross-sectional comparative study at an inner-city academic medical centre (annual ED visit census 86 000). Patients aged 75 years or greater were evaluated for inclusion, 163 were screened, 150 were deemed eligible and 117 were enrolled. The research team completed the O3DY, SBT and Mini-Mental State Exam (MMSE) for each participant. Descriptive statistics were calculated. Sensitivity and specificity of the O3DY and SBT were calculated in STATA V.11.2 using the MMSE as our criterion standard.ResultsWe enrolled 117 patients from June to November 2016. The median ED length of stay at the time of completion of all tests was 1:40 (IQR 1:34–1:46). The sensitivity of the O3DY was 71.4% (95% CI 47.8 to 95.1), and specificity was 56.3% (46.7–65.9). Sensitivity of the SBT was 85.7% (67.4–99.9) and specificity was 58.3% (48.7–67.8). The receiver operating characteristic area under the curve was calculated for the O3DY (0.51; 95% CI 0.42 to 0.61) and SBT (0.52; 95% CI 0.43 to 0.61) relative to the MMSE. Inter-rater reliability for the O3DY (k=0.64) and SBT (k=0.63) were good.ConclusionIn a cohort of geriatric patients presenting to an inner-city academic ED, the O3DY and SBT tools demonstrate moderate sensitivity and specificity for the detection of CD. Inter-rater reliability for the O3DY and SBT were good. Future research on this topic should attempt to derive and validate ED-specific screening tools, which will hopefully result in more robust likelihood ratios for the screening of CD in ED geriatric patients.</jats:sec

TikTok and public health: a proposed research agenda.

TikTok is a short video sharing social media platform that has grown rapidly since its launch, amassing over 1 billion monthly global users as of September 2021. ► We argue that public health is served by paying urgent attention to the potential health- related implications of TikTok and suggest research agenda to inform decision- makers, health providers, researchers and the public. ► Specific research priorities include investigating health- harming product promotion, medical advice/illness portrayal, dis/misinformation spread, sensitive or hateful content dissemination, problematic usage or addiction and platform corporate activity

Cognitive Impairment in Marginally Housed Youth: Prevalence and Risk Factors

Objective:&nbsp;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:&nbsp;Participants (N&nbsp;= 101) aged 20–29 years old were recruited from single-room occupancy hotels, and underwent cognitive, psychiatric, neurological, and serological assessments. Results:&nbsp;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:&nbsp;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

INCRESE: Development of an Inventory to Characterize Recorded Mental Health Recovery Narratives

Objective: Mental health recovery narratives are increasingly used in clinical practice, public health campaigns, and a directly-accessed online resources. No instrument exists to describe characteristics of individual recovery narratives. The aims were to develop and evaluate an inventory to characterize recorded recovery narratives. Research Design and Methods: A preliminary version of the Inventory of Characteristics of Recovery Stories (INCRESE) was generated from an existing&nbsp;theory-base. Feasibility and acceptability were evaluated by two coders each rating 3- purposively-selected narratives. A refined version was produced and a formal evaluation conducted. Reliability was assessed by four coders each rating 95 purposively-selected narratives. Inter-coder reliability was assessed using Fleiss’s kappa coefficients; test-retest reliability was assessed using intra-class correlation coefficients (ICCs). Results:&nbsp; Multiple refinements to description, coding categories, and language were made. Data completeness was high, and no floor or ceiling effects were found. Inter-coder reliability ranged from moderate (k=0.58) to perfect (k=1.00) agreement. Test-retest reliability ranged from moderate (ICC=0.57) to complete (ICC=1.00) agreement. The final INCRESE comprises 77 items spanning five sections: Narrative Eligibility; Narrative Mode; Narrator Characteristics; Narrative Characteristics; Narrative Content.&nbsp; Conclusion: INCRESE is the first evaluated tool to characterize mental health recovery narratives. It addresses current concerns around normative recovery narratives being used to promote compulsory wellness, e.g. by identifying narratives that reject diagnosis as an explanatory model and those with non-upward trajectories. INCRESE can be used to establish the diversity of a narrative collection and will be used in the NEON trials (ISRCTN11152837, ISRCTN63197153, ISRCTN76355273) to allow a recommender system to match narratives to participants

Can youth-engaged research facilitate equitable access to contraception in Canada? The qualitative study protocol for the Ask Us project.

INTRODUCTION: There is little to no evidence in Canada on the barriers that youth face when accessing contraception. We seek to identify the contraception access, experiences, beliefs, attitudes, knowledge, and needs of youth in Canada, from the perspectives of youth and youth service providers. METHODS AND ANALYSIS: This prospective, mixed-methods, integrated knowledge mobilisation study, the Ask Us project, will involve a national sample of youth, healthcare and social service providers, and policy makers recruited via a novel relational mapping and outreach approach led by youth. Phase I will centre the voices of youth and their service providers through in-depth one-on-one interviews. We will explore the factors influencing youth access to contraception, theoretically guided by Levesque's Access to Care framework. Phase II will focus on the cocreation and evaluation of knowledge translation products (youth stories) with youth, service providers, and policy makers. ETHICS AND DISSEMINATION: Ethical approval was received from the University of British Columbia's Research Ethics Board (H21-01091). Full open-access publication of the work will be sought in an international peer-reviewed journal. Findings will be disseminated to youth and service providers through social media, newsletters, and communities of practice, and to policy makers through invited evidence briefs and face-to-face presentations

Towards the use of mixed methods inquiry as best practice in health outcomes research

Mixed methods research (MMR) has found an increased interest in the field of health outcomes research. Consideration for both qualitative and quantitative perspectives has become key to contextualising patient experiences in a clinically meaningful measurement framework. The purpose of this paper is to outline a process for incorporating MMR in health outcomes research to guide stakeholders in their understanding of the essence of mixed methods inquiry. In addition, this paper will outline the benefits and challenges of MMR and describe the types of support needed for designing and conducting robust MMR measurement studies. MMR involves the application of a well-defined and pre-specified research design that articulates purposely and prospectively, qualitative and quantitative components to generate an integrated set of evidence addressing a single research question. Various methodological design options are possible depending on the research question. MMR designs allow a research question to be studied thoroughly from different perspectives. When applied, it allows the strengths of one approach to complement the restrictions of another. Among other applications, MMR can be used to enhance the creation of conceptual models and development of new instruments, to interpret the meaningfulness of outcomes in a clinical study from the patient perspective, and inform health care policy. Robust MMR requires research teams with experience in both qualitative and quantitative research. Moreover, a thorough understanding of the underlying principles of MMR is recommended at the point of study conception all the way through to implementation and knowledge dissemination. The framework outlined in this paper is designed to encourage health outcomes researchers to apply MMR to their research and to facilitate innovative, patient-centred methodological solutions to address the complex challenges of the field.Other UBCNon UBCReviewedFacult

Measuring the Bright Side of Being Blue: A New Tool for Assessing Analytical Rumination in Depression

Background: Diagnosis and management of depression occurs frequently in the primary care setting. Current diagnostic and management of treatment practices across clinical populations focus on eliminating signs and symptoms of depression. However, there is debate that some interventions may pathologize normal, adaptive responses to stressors. Analytical rumination (AR) is an example of an adaptive response of depression that is characterized by enhanced cognitive function to help an individual focus on, analyze, and solve problems. To date, research on AR has been hampered by the lack of theoretically-derived and psychometrically sound instruments. This study developed and tested a clinically meaningful measure of AR. Methods: Using expert panels and an extensive literature review, we developed a conceptual framework for AR and 22 candidate items. Items were field tested to 579 young adults; 140 of whom completed the items at a second time point. We used Rasch measurement methods to construct and test the item set; and traditional psychometric analyses to compare items to existing rating scales. Results: Data were high quality (,1 % missing; high reliability: Cronbach’s alpha = 0.92, test-retest intraclass correlations.0.81; evidence for divergent validity). Evidence of misfit for 2 items suggested that a 20-item scale with 4-point response categories best captured the concept of AR, fitting the Rasch model (x2 = 95.26; df = 76, p = 0.07), with high reliability (rp = 0.86), ordered response scale structure, and no item bias (gender, age, time)

TikTok and #OccupationalTherapy: Cross-sectional Study

BackgroundMedical providers use the short-form video social media platform TikTok to share information related to their scope of practice and insights about their professions. Videos under the hashtag #occupationaltherapy on TikTok have over 100 million views, but there is no evidence investigating how occupational therapy information and knowledge are shared on the platform. ObjectiveThe purpose of this cross-sectional study is to describe TikTok content with the hashtag #occupationaltherapy and investigate how occupational therapy is portrayed. MethodsWe performed a content analysis on the top 500 TikTok videos under the hashtag #occupationaltherapy. We analyzed occupational therapy content themes (occupational therapy intervention, education, student training, universal design, and humor), practice settings (pediatrics, generalists, dementia, hand therapy, neurology, occupational therapy students, older adults, mental health, and unknown), and sentiments (positive, negative, and neutral). ResultsThe videos in our sample (n=500) received 175,862,994 views. The 2 most prevalent content areas were education (n=210) and occupational therapy interventions (n=146). The overall sentiment of the videos was positive (n=302). The most frequently observed practice settings in the videos were pediatrics (n=131) and generalists (n=129). Most videos did not state that it was occupational therapy (n=222) or misused the hashtag (n=131). ConclusionsTikTok has the potential for occupational therapists to share innovations, build communities of practice, and engage in collaborative efforts to share information about occupational therapists’ unique roles with diverse populations. Future research is needed to monitor the quality of information and debunk inaccuracies

Psychometric performance of the PROMIS® depression item bank: a comparison of the 28- and 51-item versions using Rasch measurement theory

Purpose: The aim of this study is to illustrate an example application of Rach Measurement Theory (RMT) in the evaluation of patient-reported outcome (PRO) measures. RMT diagnostic methods were applied to evaluate the PROMIS® Depression items as part of a series of papers applying different psychometric paradigms in parallel to the same data. Methods: RMT was used to examine scale-to-sample targeting, scale performance and sample measurement of two PROMIS depression item pools including respectively 28 and 51- items. Results: Sub-optimal but improved targeting was displayed in the 51-item pool which covered 27% of the range of depression measured in the sample compared to only 15% in the 28-item bank, further reducing the sample percentage with lower depression not covered by the scale (28% Vs 34%). Satisfactory scale performance was observed by the 28-item bank with marginal item misfit. However, deviations from the RMT criteria in the 51-itempool were observed including: 9 reversed thresholds; 12 misfitting items and 12 item-pairs displaying dependency. Overall reliability was good for sets of items (Person Separation Index = 0.93 and 0.95), but sub-optimal sample measurement (17% Vs 19% fit residuals outside of the recommended range). Conclusions: The RMT approach in this exercise provided evidence that compared to the 28-item bank, the extended 51-item version of the PROMIS depression, improved sample-to-scale targeting. However, targeting in the lower end of the concept of interest remained sub-optimal and scale performance deteriorated. There may be a need to improve the conceptual breadth of the construct under investigation to ensure the inclusion of items that capture the full range of the concept of interest for this context of use.Medicine, Faculty ofNon UBCOccupational Science and Occupational Therapy, Department ofReviewedFacult
