Despite limited evidence of efficacy, opioid analgesics are frequently used by patients for chronic pain while awaiting total hip or knee arthroplasty (THA or TKA). Preoperative use of opioids is problematic as it increases the likelihood of postoperative opioid-related adverse drug events and postoperative complications and is the strongest predictor of persistent opioid use post surgery. Opioid tapering prior to elective surgery has been proposed as a strategy for mitigating harms and improving postoperative outcomes. This protocol describes a randomised clinical trial, which aims to determine the effectiveness of a preoperative pharmacist-partnered opioid tapering programme compared with standard care for patients awaiting elective THA or TKA on postoperative outcomes including persistent opioid use.

Eligible participants must be aged ≥18 years; awaiting elective unilateral or bilateral THA or TKA; speak and read English; use prescription opioid analgesics at least 4 days a week and have access to internet or telephone. The participants will be excluded if they are undergoing a repeat surgery (same procedure within 6 months), are using opioids for cancer, palliative care or substance use disorder; have previously or are currently undergoing an opioid tapering programme or active medication review or have cognitive impairment. Enrolled participants will be randomised in a 1:1 ratio in permuted blocks of two and four to: (1) intervention or (2) standard care. A total of 314 participants will be recruited into the study. The intervention will include a pharmacist-partnered opioid tapering programme in which a pharmacist will work with participants to reduce their opioid dose over a 3-month period before surgery. Standard care will involve review by the hospital preadmission clinic multidisciplinary team to assess medical, physical and psychological health prior to surgery and education sessions for preoperative and postoperative care. The primary outcome assessed is persistent opioid use 3 months post surgery. The key secondary outcome is total Western Ontario and McMaster Universities Arthritis Index score. Data analysis will be performed using an estimand framework, with a generalised estimating equation model for the primary outcome from 1 day to 3 days presurgery to 3 months post surgery and a multilevel model for the main secondary outcome from baseline to 3 months after surgery. Cost-effectiveness and cost-utility analyses will be conducted to determine whether the intervention is cost-effective from the healthcare system perspective.

Ethics approval for this study was granted by a Human Research Ethics Committee (approval number: 2023/ETH01042). Results will be disseminated in peer reviewed journals, at international scientific meetings as well as meetings with key stakeholders and via the media.

Effective prevention of maternal-fetal transmission of hepatitis B virus (HBV) in highly endemic settings depends on targeting vaccination efforts to key priority groups, including pregnant women. However, the extent of HBV vaccination and determinants of uptake in sub-Saharan Africa (SSA) have not been systematically examined. This systematic review aims to estimate HBV vaccination among pregnant women in SSA and identify the broader factors influencing uptake.

This review will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) guidelines. A comprehensive literature search will be conducted in MEDLINE, Embase, Web of Science, Scopus, African Journals Online and Google Scholar in November 2025. We will include published observational studies that assess HBV vaccination among pregnant women in SSA countries from database inception to October 2025. A meta-analysis will be conducted using random-effects models to pool estimates of HBV vaccination and multivariable-adjusted ORs for vaccination-associated factors. Statistical heterogeneity will be assessed using the I² statistic.

Ethical approval is not required as this review will not involve primary data collection. Findings will be published in a peer-reviewed journal, presented at regional and international public health conferences, and, where applicable, shared with policymakers and health authorities in SSA.

This protocol is registered with the International Prospective Register of Systematic Reviews, registration number CRD420251120357.

Diabetes mellitus is a significant global health challenge, requiring innovative strategies to improve management and mitigate complications. Digital health technologies offer promising solutions to enhance diabetes self-care by providing real-time feedback, improving communication and supporting data-driven decision-making. Despite the increasing adoption of digital self-care interventions, there is a lack of comprehensive synthesis of evidence on their impact, accessibility and integration into healthcare systems. This scoping review aims to map existing research on digital self-care solutions for diabetes management, identify knowledge gaps and highlight best practices and key factors influencing adoption.

The review will follow Arksey and O’Malley’s framework and adhere to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. A systematic search will be conducted in Medline, Scopus, Embase, CINAHL and Google Scholar, focusing on studies published from January 2004 to December 2024 in English, French, Arabic, Portuguese, Spanish, Italian, Czech, Slovak and Chinese. Studies reporting on digital self-care solutions for diabetes management will be included, covering experimental and quasi-experimental study designs. Data extraction will cover study and participant characteristics, digital solution features, and barriers and facilitators to adoption. Ethical and equity considerations will also be analysed using established frameworks. Two reviewers will independently screen studies, with discrepancies resolved by a third reviewer.

This scoping review will provide a comprehensive understanding of digital self-care solutions for diabetes management, offering insights to inform future research and enhance self-care practices globally. Findings will be disseminated through peer-reviewed publications, conferences and interest holder engagements to inform clinical practice and policy development. As this study involves the review of existing literature, ethical approval is not required.
