People with chronic pain are a high health service using population, representing a significant proportion of primary care visits, but their health service use and needs have been largely understudied. This mixed-methods study investigates experiences of accessing primary care services for people with chronic pain in British Columbia (BC), Canada.

This research programme includes a retrospective cohort study using administrative data, semistructured interviews with people with chronic pain, and triangulation of data. The aim is to support a more robust understanding of how people with chronic pain access primary care services and how this impacts other health services use. These studies emphasise the importance of lived/living experience of chronic pain through the inclusion of individuals with lived experience on the research team and study council, qualitative interviews with people with chronic pain and application of a critical disability theory lens.

We have obtained ethics approvals from the Simon Fraser University research ethics board. Population Data BC has granted access to de-identified administrative data. Study findings will be disseminated through academic outputs and through knowledge mobilisation with relevant community partners.

The literature examining direct-to-consumer (DTC) commercial virtual care has expanded rapidly over the past decade. Our objective was to synthesise the nature and range of evidence on DTC commercial virtual care.

We included original research studies published in English or French between 1 January 2016 and 30 April 2025 that assessed DTC commercial virtual care in all contexts and in all populations.

Screening titles and abstracts, and full-text manuscripts, and extracting data was done in duplicate. We analysed quantitative data using descriptive statistics and reported findings in tables. We provided a narrative summary of textual data.

After excluding duplicates, we identified 8055 studies for title and abstract screening; 691 articles for full-text screening; and 103 studies meeting our inclusion criteria. 32 studies (31.1%) reported financial ties to the virtual care industry. 67 (65.0%) studies were conducted in the USA. Studies were largely quantitative (87/103 (84.5%)) or mixed methods (8/103 (7.8%)) studies and used cross-sectional (85/95 (89.5%)) designs. Most quantitative studies were descriptive, reporting on quality of care, health outcomes, platform characteristics and patient views, with only 24 of the 95 quantitative studies (25.3%) including a control or comparison group. 18 of these 24 studies (75.0%) compared the quality of care, costs and/or utilisation to other models of care and reported variable findings. The rest compared patient characteristics. Few studies assessed clinician perspectives or addressed privacy-related ethical concerns.

Despite a large number of studies assessing DTC commercial virtual care, we have little insight into impacts on quality of care, health outcomes, health system utilisation and privacy-related ethical concerns. The financial ties with industry suggest that there may be bias in the body of research literature.

The introduction of fentanyl and its analogues in the illicit drug supply has prompted greater emphasis on refining clinical treatment protocols to ensure sustained retention in opioid agonist treatment (OAT). Take-home dosing may lessen the treatment burden on clients and thus reduce the risk of treatment discontinuation. The evidence base supporting the use of take-home dosing, including the optimal duration of dispensations, is, however, limited. The objective of this study is to determine the comparative effectiveness of alternative take-home dosing schedules, as observed in clinical practice in British Columbia, Canada from 2010 to 2022.

We propose to emulate a target trial with a population-level retrospective study of individuals initiating methadone or buprenorphine/naloxone between 1 January 2010 and 31 December 2022 who are 18 years of age or older and not currently incarcerated or pregnant with no history of cancer or palliative care. Our study will draw on nine linked health administrative databases from British Columbia and will evaluate take-home doses of 2–5 days, 6 days or >6 days compared with continuous daily dosing. The primary outcomes include OAT discontinuation and all-cause mortality on treatment. A causal per-protocol analysis is proposed with longitudinal matching and inverse probability of censoring weighting approaches to adjust for time-fixed and time-varying confounding. A range of sensitivity analyses will be executed to determine the robustness of results.

The protocol, cohort creation and analysis plan have been classified and approved as a quality improvement initiative by Providence Health Care Research Ethics Board and the Simon Fraser University Office of Research Ethics. Results will be disseminated and shared with local advocacy groups and decision-makers, developers of national and international clinical guidelines, presented at national and international conferences and published in peer-reviewed journals electronically and in print.

Telemedicine use has risen significantly since the COVID-19 pandemic. Evidence suggests that the quality of care in telemedicine could be as good as in-person care, but this is likely context-dependent. Expert guidelines have declared the appropriate medical conditions, but often without empirical evidence that grapples with the fundamental information limitations facing telemedicine. We draw on the task-technology fit theory and empirical evidence around human communication to examine how the medical and social contexts affect the efficiency and clinical quality of primary care.

We will use a population-based dataset from the Canadian province of British Columbia (BC) to inform a quasi-experimental study using propensity score matching (PSM). The treatment group will consist of telemedicine visits from April to December 2022. We will use PSM to create a control group of matched, in-person visits in the same period. We will then use cluster-robust linear regression to identify how specific medical conditions and social contexts are associated with higher rates of prescription, follow-up with primary care providers, emergency department visits and acute care admissions. We plan for the study to take place from 1 August 2025 to 1 August 2026.

The Research Ethics BC has granted approval for this study (H21-02244-A006). Our findings will be shared with patients, healthcare providers and policymakers and disseminated through conference presentations and peer-reviewed publications.

Chronic low back pain (CLBP) and depressive symptoms (DS) are highly prevalent, burdensome, costly and comorbid health conditions. Osteopathic manipulative treatment (OMT) was shown to improve pain and disability in patients with CLBP; however, the effect on comorbid DS remains less certain. Interestingly, CLBP and DS seem to be associated with changes in interoception, which may be reversed by OMT.

The study protocol proposes a single-blinded, parallel-group, randomised controlled trial to investigate the effect of OMT on clinical symptoms (depression, pain and disability) and interoceptive functions (interoceptive accuracy, sensibility and awareness) in patients with CLBP and comorbid DS. A sample of 60 adult subjects with CLBP and comorbid DS shall be recruited from osteopathic, orthopaedic and physiotherapeutic practices and educational institutes for osteopathy, sports science, psychology and medicine in Hamburg, Germany. Participants will be randomly allocated (1:1 ratio) to receive six 45 min treatment sessions of either OMT (standard-OMT group) or sham treatment imitating OMT (sham-OMT group). Primarily, symptoms of depression, pain and disability will be assessed with the Beck’s Depression Inventory, Second Edition (BDI-II), Numeric Rating Scale (NRS) and Oswestry Disability Index (ODI). Secondarily, interoceptive accuracy, sensibility and awareness will be evaluated using the Heartbeat Tracking Task (HTT), Multidimensional Assessment of Interoceptive Awareness (MAIA-2) and confidence-accuracy correspondence (CAC). Ancillary, the therapeutic alliance will be investigated with the Helping Alliance Questionnaire. Data will be collected at baseline (t₀), the first, third and sixth treatment sessions (t₁, t₃, t₆) and at 3 months follow-up (t₇). The findings will be analysed for between-group differences using descriptive (mean and SD) and inductive statistics (mixed analysis of variance). It is hypothesised that standard-OMT, compared with sham-OMT, will reduce depression, pain and disability (BDI-II, NRS, ODI) and increase interoceptive accuracy, sensibility and awareness (HTT, MAIA-2, CAC) in patients with CLBP and comorbid DS.

The study was approved by the ethics committee of the Medical School Hamburg (MSH-2023/288). The anonymised dataset will be published in an online repository, and the results will be published in peer-reviewed scientific journals.
