Article Synopsis
  • Prehospital telemedicine triage systems using machine learning (ML) can help improve emergency care by accurately identifying low-acuity patients, but research in this area is still limited due to challenges like overcrowding in emergency departments.!
  • The scoping review aimed to summarize existing ML-enhanced telemedicine triage methods by examining data sources, predictors, labeling techniques, ML models, and performance metrics used in various studies.!
  • Out of 165 records screened, 15 studies were included, with most of them implementing ML methods to enhance triage accuracy in emergency medical situations, highlighting both the potential and the research gaps that still need to be addressed.!

Background: British Columbia has over 200 rural, remote, and Indigenous communities that have limited health care resources due to physician isolation, sparsity in clinical resources, the lack of collegial support, and provider burnout. Real-time virtual support (RTVS) peer-to-peer pathways provide support to patients and providers. Amid the COVID-19 pandemic exacerbating existing health care disparities and equitable access to timely care, RTVS presents a portable and additional opportunity to be deployed in a hospital or patient home setting in rural communities.

Background: British Columbia 8-1-1 callers who are advised by a nurse to seek urgent medical care can be referred to virtual physicians (VPs) for supplemental assessment and advice. Prior research indicates callers' subsequent health service use may diverge from VP advice. We sought to 1) estimate concordance between VP advice and subsequent health service use, and 2) identify factors associated with concordance to understand potential drivers of discordant cases.

Article Synopsis
  • - The COVID-19 pandemic prompted a collaboration of organizations in British Columbia to create seven virtual care pathways through the Real-Time Virtual Support (RTVS) network, aimed at improving healthcare access for rural, remote, and Indigenous communities.
  • - From April 2020 to March 2021, these pathways facilitated 38,905 patient encounters and provided over 29,500 hours of peer-to-peer support, showing a significant monthly growth in usage of 178%.
  • - Satisfaction rates were high, with 90% of patients and 94% of providers expressing positive experiences, indicating the pathways effectively addressed healthcare needs in underserved communities.

Background: British Columbia's 8-1-1 telephone service connects callers with nurses for health care advice. As of Nov. 16, 2020, callers advised by a registered nurse to obtain in-person medical care can be subsequently referred to virtual physicians.

Background: South Asian community members in Canada experience a higher burden of chronic disease than the general population. Digital health innovations provide a significant opportunity to address various health care challenges such as supporting patients in their disease self-management. However, South Asian community members are less likely to use digital tools for their health and face significant barriers in accessing them because of language or cultural factors.

Background: British Columbia, like many jurisdictions, has a health information telephone service (8-1-1) to provide callers with information by registered nurses and help them decide whether to attend an emergency department or primary care clinic, or manage their concern at home. We describe a new service, HealthLink BC Emergency iDoctor-in-assistance (HEiDi), that partnered physicians available by videoconferencing with 8-1-1 registered nurses to support callers.

Methods: From Apr.

Promoting digital health literacy and healthy lifestyle behaviours in children can lead to positive long-term health outcomes and prevent chronic diseases. However, there are few school-based interventions promoting this education to intermediate elementary students. The objective of this study was to test the effectiveness of a novel intervention to increase students' digital health literacy and health knowledge.

Background: Intensive lifestyle interventions are effective in reducing the risk of type 2 diabetes, but the implementation of learnings from landmark studies is expensive and time consuming. The availability of digital lifestyle interventions is increasing, but evidence of their effectiveness is limited.

Objective: This randomized controlled trial (RCT) aimed to test the feasibility of a web-based diabetes prevention program (DPP) with step-dependent feedback messages versus a standard web-based DPP in people with prediabetes.

Background: Motivational interviewing (MI) enhanced with behaviour change techniques (BCTs) and deployed by health trainers targeting multiple risk factors for cardiovascular disease (CVD) may be more effective than interventions targeting a single risk factor.

Objectives: The clinical effectiveness and cost-effectiveness of an enhanced lifestyle motivational interviewing intervention for patients at high risk of CVD in group settings versus individual settings and usual care (UC) in reducing weight and increasing physical activity (PA) were tested.

Design: This was a three-arm, single-blind, parallel randomised controlled trial.

Objective: The epidemic of obesity is contributing to the increasing prevalence of people at high risk of cardiovascular disease (CVD), negating the medical advances in reducing CVD mortality. We compared the clinical and cost-effectiveness of an intensive lifestyle intervention consisting of enhanced motivational interviewing in reducing weight and increasing physical activity for patients at high risk of CVD.

Methods: A three-arm, single-blind, parallel-group randomised controlled trial was conducted in consenting primary care centres in south London.

Background: The increasing prevalence of type 2 diabetes and suboptimal glycaemic control in Kuwait requires novel, wide-reaching, low-cost interventions to motivate and mobilise individuals towards more effective self-management. More than 2 million people in Kuwait own mobile phones. We will test whether automated personalised health text messages based on principles of motivational interviewing and are responsive to biodata delivered remotely is potentially effective in improving glycaemic control compared to usual care.

Previous studies linking parent ADHD symptoms to parenting have typically focused on each parent individually. To provide a broader understanding of family context, in this study, levels of inattention and hyperactivity-impulsivity in mothers and fathers were examined, both individually and in combination, in relation to negative parenting and child-rearing disagreements. Two-parent families of 5 to 13 year old boys (126 with ADHD and 53 typically developing) participated.

Background: The ability to function at work is impaired in patients with major depressive disorder (MDD) but few clinical trials include occupational outcome assessments. This study examined whether symptom remission following treatment for MDD is associated with work functioning improvement.

Methods: We conducted a secondary analysis of a 12-week randomized clinical trial comparing escitalopram with or without telephone-administered cognitive therapy in employed patients with MDD (N = 86).

Objective: We tested the similarity-fit hypothesis that predicts more positive parenting when both parent and child have high levels of ADHD symptoms compared to when only one does.

Method: Mothers and fathers of 156, 5 to 13 year old sons participated (110 boys with ADHD, 46 without). Parent inattentive and hyperactive-impulsive symptoms were examined, in interaction with child ADHD, as predictors of parental tolerance, empathy, encouragement of child autonomy, and positive parenting.

Article Synopsis
  • * In a study with 36 employed adults with moderate MDD, participants underwent neurocognitive testing and assessments of work performance before and after 8 weeks of treatment with desvenlafaxine, which showed overall improvements in depressive symptoms and functioning.
  • * Although there were no direct correlations found between cognitive improvements and enhancements in work performance, those who showed notable neurocognitive gains experienced greater overall improvements in their mental health and job functioning compared to those who did not.

Background: Burnout - physical or psychological fatigue in the personal, work and client-related work domains - appears to share numerous overlapping characteristics with major depressive episodes. However, whether burnout and depression are in fact separate conditions is still ambiguous. Our aim was to examine burnout in a clinically depressed patient sample.
