Cross-sectional survey of the Mental health and Addictions effects, Service impacts and Care needs of children, youth and families during the COVID-19 pandemic: the COVID-19 MASC study protocol.

INTRODUCTION: The COVID-19 pandemic has had a tremendous negative effect on the mental health and well-being of Canadians. These mental health challenges are especially acute among vulnerable Canadian populations. People living in Canada's most populous province, Ontario, have spent prolonged time in lockdown and under public health measures and there is a gap in our understanding of how this has impacted the mental health system. This protocol describes the Mental health and Addictions Service and Care Study that will use a repeated cross-sectional design to examine the effects, impacts, and needs of Ontario adults during the COVID-19 pandemic. METHODS AND ANALYSIS: A cross-sectional survey of Ontario adults 18 years or older, representative of the provincial population based on age, gender and location was conducted using Delvinia's AskingCanadians panel from January to March 2022. Study sample was 2500 in phases 1 and 2, and 5000 in phase 3. The Alcohol, Smoking and Substance Involvement Screening Test and Diagnostic Statistical Manual-5 Self-Rated Level 1 Cross-Cutting Symptom Measure-Adult were used to assess for substance and mental health concerns. Participants were asked about mental health and addiction service-seeking and/or accessing prior to and during the pandemic. Analyses to be conducted include: predictors of service access (ie, sociodemographics, mental illness and/or addiction, and social supports) before and during the pandemic, and χ2 tests and logistic regressions to analyse for significant associations between variables and within subgroups. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Sunnybrook Research Ethics Board. Dissemination plans include scientific publications and conferences, and online products for stakeholders and the general public.

A Longitudinal Cohort Study of Youth Mental Health and Substance use Before and During the COVID-19 Pandemic in Ontario, Canada: An Exploratory Analysis.

BACKGROUND: Youth mental health appears to have been negatively impacted by the COVID-19 pandemic. The impact on substance use is less clear, as is the impact on subgroups of youth, including those with pre-existing mental health or substance use challenges. OBJECTIVE: This hypothesis-generating study examines the longitudinal evolution of youth mental health and substance use from before the COVID-19 pandemic to over one year into the pandemic among youth with pre-existing mental health or substance use challenges. METHOD: A total of 168 youth aged 14-24 participated. Participants provided sociodemographic data, as well as internalizing disorder, externalizing disorder, and substance use data prior to the pandemic's onset, then every two months between April 2020-2021. Linear mixed models and Generalized Estimating Equations were used to analyze the effect of time on mental health and substance use. Exploratory analyses were conducted to examine interactions with sociodemographic and clinical characteristics. RESULTS: There was no change in internalizing or externalizing disorder scores from prior to the pandemic to any point throughout the first year of the pandemic. Substance use scores during the pandemic declined compared to pre-pandemic scores. Exploratory analyses suggest that students appear to have experienced more mental health repercussions than non-students; other sociodemographic and clinical characteristics did not appear to be associated with mental health or substance use trajectories. CONCLUSIONS: While mental health remained stable and substance use declined from before the COVID-19 pandemic to during the pandemic among youth with pre-existing mental health challenges, some youth experienced greater challenges than others. Longitudinal monitoring among various population subgroups is crucial to identifying higher risk populations. This information is needed to provide empirical evidence to inform future research directions.

Youth in a pandemic: a longitudinal examination of youth mental health and substance use concerns during COVID-19.

OBJECTIVE: This study analyses longitudinal data to understand how youth mental health and substance use are evolving over the course of the COVID-19 pandemic, which is critical to adjusting mental health response strategies. SETTING: Participants were recruited from among existing participants in studies conducted in an urban academic hospital in Ontario, Canada. PARTICIPANTS: A total of 619 youth aged 14-28 years participated in the study (62.7% girls/young women; 61.4% Caucasian). MEASURES: Data on mood, substance use and COVID-19-related worries were collected over four time points, that is, every 2 months beginning in the early stages of the pandemic in April 2020. Latent class analyses were conducted on the longitudinal data to identify distinct groups of youth who have different trajectory profiles of pandemic impact on their mood, substance use and COVID-19-related worries. RESULTS: For the majority of participants, mood concerns increased early in the pandemic, declined over Canada's summer months and subsequently increased in autumn. Among the youth with the highest level of mood symptoms at the beginning of the pandemic, increases in mental health concerns were sustained. Substance use remained relatively stable over the course of the pandemic. COVID-19-related worries, however, followed a trajectory similar to that of mood symptoms. Girls/young women, youth living in urban or suburban areas, in larger households, and with poorer baseline mental and physical health are the most vulnerable to mental health concerns and worries during the pandemic. CONCLUSIONS: Youth mental health symptom levels and concerns are evolving over the course of the COVID-19 pandemic, in line with the evolution of the pandemic itself, and longitudinal monitoring is therefore required. It is also essential that we engage directly with youth to cocreate pandemic response strategies and mental health service adaptations to best meet the needs of young people.

Lessons learnt from the impact of COVID-19 on arthroplasty services in Hong Kong: how to prepare for the next pandemic?

BACKGROUND: Arthroplasty services worldwide have been significantly disrupted by the pandemic of coronavirus disease 2019 (COVID-19). This retrospective comparative study aimed to characterize its impact on arthroplasty services in Hong Kong. METHODS: From January 1 to June 30, 2020, the patients of "COVID-19 cohort" underwent elective total hip or knee replacement in Hong Kong public hospitals. The cohort was compared to the "control cohort" during the same period in 2019. Data analysis was performed to compare the two cohorts' numbers of operations, hospital admission, orthopaedic clinic attendances, and waiting time. RESULTS: A total of 33,111 patient episodes were analyzed. During the study period, the elective arthroplasty operations and hospitalizations decreased by 53 and 54%, respectively (P < 0.05). Reductions were most drastic from February to April, with surgical volume declining by 86% (P < 0.05). The primary arthroplasty operations decreased by 91% (P < 0.05), while the revision operations remained similar. Nevertheless, 14 public hospitals continued performing elective arthroplasty for patients with semi-urgent indications, including infection, progressive bone loss, prosthesis loosening, dislocation or mechanical failure of arthroplasty, and tumor. At the institution with the highest arthroplasty surgical volume, infection (28%) was the primary reason for surgery, followed by prosthesis loosening (22%) and progressive bone loss (17%). The orthopaedic clinic attendances also decreased by 20% (P < 0.05). Increases were observed in waiting time and the total number of patients on the waiting list for elective arthroplasty. CONCLUSIONS: Despite the challenges, public hospitals in Hong Kong managed to continue providing elective arthroplasty services for high-priority patients. Arthroplasty prioritization, infection control measures, and post-pandemic service planning can enhance hospital preparedness to mitigate the impact of current and future pandemics.

The Impact of a Harry Potter-Based Cognitive-Behavioral Therapy Skills Curriculum on Suicidality and Well-being in Middle Schoolers: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the impact of a Harry Potter-based mental health literacy curriculum, imparting cognitive behavioral therapy (CBT) skills, on suicidality and well-being in middle-schoolers. METHODS: Students (aged 11-14; grades 7-8) who received a 3-month teacher-delivered intervention embedded in the language arts curriculum (N=200) were compared to a wait-list control group (N=230) in the largest urban school board in Canada. Suicidality defined as a composite measure of self-reported suicidal ideation and attempts [primary outcome], self-reported emotion dysregulation, interpersonal chaos, confusion about self, and impulsivity [Life Problems Inventory (LPI)] and self-reported depression and anxiety symptoms [Revised Child Anxiety and Depression Scale (RCADS)] were the outcomes of interest. Measurements occurred prior to and after curriculum delivery with independent t-tests used to compare mean change scores between groups clustered by class. RESULTS: Thirty-seven English teachers in 46 classes across 15 schools comprised the planned study cohort. Composite suicidality scores were significantly worse in the control than intervention group at endpoint (0.05±0.54 vs. 0.17±0.47, t= -2.60, df=428, p=0.01). There were also significant improvements in LPI and RCADS scores in the intervention group compared to controls (LPI:-3.74±7.98 vs. 1.16±10.77 t=5.28, df=428, p<.001; RCADS: (-3.08±5.49 vs. -1.51±6.53 t=2.96, df=429, p=0.01). Sub-analyses revealed that these improvements were largely driven by a significant difference in scores in girls. LIMITATIONS: Sample size constraints as study terminated prematurely during COVID pandemic. CONCLUSIONS: This study demonstrates significant improvement in suicidality, emotional regulation, self-concept, interpersonal difficulties, depression and anxiety in youth, particularly girls following this intervention. Replication studies in larger samples are needed to confirm these results.

Impacts of COVID-19 on Youth Mental Health, Substance Use, and Well-being: A Rapid Survey of Clinical and Community Samples: Répercussions de la COVID-19 sur la santé mentale, l'utilisation de substances et le bien-être des adolescents : un sondage rapide d'échantillons cliniques et communautaires.

OBJECTIVES: The current novel coronavirus disease of 2019 (COVID-19) pandemic presents a time-sensitive opportunity to rapidly enhance our knowledge about the impacts of public health crises on youth mental health, substance use, and well-being. This study examines youth mental health and substance use during the pandemic period. METHODS: A cross-sectional survey was conducted with 622 youth participants across existing clinical and community cohorts. Using the National Institute of Mental Health-developed CRISIS tool and other measures, participants reported on the impacts of COVID-19 on their mental health, substance use, and other constructs. RESULTS: Reports of prepandemic mental health compared to intrapandemic mental health show a statistically significant deterioration of mental health across clinical and community samples (P < 0.001), with greater deterioration in the community sample. A total of 68.4% of youth in the clinical sample and 39.9% in the community sample met screening criteria for an internalizing disorder. Substance use declined in both clinical and community samples (P < 0.001), although 23.2% of youth in the clinical sample and 3.0% in the community sample met screening criteria for a substance use disorder. Participants across samples report substantial mental health service disruptions (48.7% and 10.8%) and unmet support needs (44.1% and 16.2%). Participants report some positive impacts, are using a variety of coping strategies to manage their wellness, and shared a variety of ideas of strategies to support youth during the pandemic. CONCLUSIONS: Among youth with histories of mental health concerns, the pandemic context poses a significant risk for exacerbation of need. In addition, youth may experience the onset of new difficulties. We call on service planners to attend to youth mental health during COVID-19 by bolstering the accessibility of services. Moreover, there is an urgent need to engage young people as coresearchers to understand and address the impacts of the pandemic and the short, medium, and long terms.
