The Effect of Overdose Education and Naloxone Distribution: An Umbrella Review of Systematic Reviews
Background. Opioids contribute to more than 60 000 deaths annually in North America. While the expansion of overdose education and naloxone distribution (OEND) programs has been recommended in response to the opioid crisis, their effectiveness remains unclear. Objectives. To conduct an umbrella review of systematic reviews to provide a broad-based conceptual scheme of the effect and feasibility of OEND and to identify areas for possible optimization. Search Methods. We conducted the umbrella review of systematic reviews by searching PubMed, Embase, PsycINFO, Epistemonikos, the Cochrane Database of Systematic Reviews, and the reference lists of relevant articles. Briefly, an academic librarian used a 2-concept search, which included opioid subject headings and relevant keywords with a modified PubMed systematic review filter. Selection Criteria. Eligible systematic reviews described comprehensive search strategies and inclusion and exclusion criteria, evaluated the quality or risk of bias of included studies, were published in English or French, and reported data relevant to either the safety or effectiveness of OEND programs, or optimal strategies for the management of opioid overdose with naloxone in out-of-hospital settings. Data Collection and Analysis. Two reviewers independently extracted study characteristics and the quality of included reviews was assessed in duplicate with AMSTAR-2, a critical appraisal tool for systematic reviews. Review quality was rated critically low, low, moderate, or high based on 7 domains: protocol registration, literature search adequacy, exclusion criteria, risk of bias assessment, meta-analytical methods, result interpretation, and presence of publication bias. Summary tables were constructed, and confidence ratings were provided for each outcome by using a previously modified version of the Royal College of General Practitioners’ clinical guidelines. Main Results. Six systematic reviews containing 87 unique studies were included. We found that OEND programs produce long-term knowledge improvement regarding opioid overdose, improve participants’ attitudes toward naloxone, provide sufficient training for participants to safely and effectively manage overdoses, and effectively reduce opioid-related mortality. High-concentration intranasal naloxone (> 2 mg/mL) was as effective as intramuscular naloxone at the same dose, whereas lower-concentration intranasal naloxone was less effective. Evidence was limited for other naloxone formulations, as well as the need for hospital transport after overdose reversal. The preponderance of evidence pertained persons who use heroin. Author’s Conclusions. Evidence suggests that OEND programs are effective for reducing opioid-related mortality; however, additional high-quality research is required to optimize program delivery. Public Health Implications. Community-based OEND programs should be implemented widely in high-risk populations.

Revitalizing health for all : case studies of the struggle for comprehensive primary health care
\"The concept of Comprehensive Primary Health Care focuses on health system efforts to improve equity in health care access, community empowerment, participation of marginalized groups, and actions on the social determinants of health. Despite its existence since the late 1970s very few studies have been able to highlight the outcomes of this concept, until now. Revitalizing Health for All examines thirteen cases of efforts to implement CPHC reforms from around the globe including Australia, Brazil, Democratic Republic of Congo, Iran, South Africa, and more. The findings presented in this volume originate from an international action-research set of studies that utilized triads of senior and junior researchers and knowledge users from each country's public health system. Primary health care reform is an important policy discourse both at the national level in these countries and in the global conversations, and this volume reveals the similarities among CPHC projects in diverse national contexts. These similarities provide a rich evidence base from which future CPHC reform initiatives can draw, regardless of their country.\"-- Provided by publisher.

Examining the roles, relationships and power dynamics shaping universal health system policy processes in high- and upper-middle-income countries: a scoping review
Background
Policies for universal health systems aim to provide equitable access to quality healthcare. However, achieving this remains a complex goal in high and upper-middle-income countries. Despite widespread efforts, universal health system reforms vary significantly, shaped by historical, political, and economic contexts. Understanding the policy process, including the roles of various actors and institutions, is essential to improving policy effectiveness and achieving equitable health systems. This scoping review examines the literature on policy processes, stakeholder influences, and contextual factors shaping policies for universal health system reforms.
Methods
A systematic search of peer-reviewed and grey literature from 2014 to 2024 was conducted using five academic databases and Google Scholar. Seventy-four studies focused on policies for universal health systems in high and upper-middle-income countries. Data was examined in two phases. First, a descriptive analysis explored the geographic and economic contexts of the studies and their representation across stages of the policy cycle, including agenda-setting, formulation, adoption implementation, and evaluation. Topp et al.’s framework was then used to examine the influence of key actors, focusing on their relationships, power sources, and societal expressions of power.
Results
The review revealed significant geographical disparities, representing only 30% of eligible countries. Most studies focused on early policy stages, with limited attention to implementation and evaluation. A predominance of qualitative research facilitated contextual insights, yet the underrepresentation of quantitative and mixed methods approaches restricted opportunities for integrated analysis. Crises and ideological shifts were drivers of policy momentum, catalysing changes in universal health system reforms. Governments played a central role, supported or contested by civic groups, professional associations, and academia. Media often influenced public discourse and policy perceptions, amplifying or challenging reform narratives. Persistent challenges included fragmented systems, equity-efficiency tensions, and definitional ambiguities, undermining policy coherence and sustainability.
Conclusions
The review underscores the need for a broader ‘universal’ framework for understanding health system reform and prioritising equity, quality, and sustainability. Adaptive health systems, robust institutions, and standardised frameworks to address political, economic, and ideological barriers are crucial. Future research must evaluate equity impacts, refine policy design, and explore mechanisms to align reforms with universal health system principles and goals.

Benefit of China's Social Health Insurance Schemes: Trend Analysis and Associated Factors Since Health Reform
With the deepening of health insurance reform in China, the integration of social health insurance schemes was put on the agenda. This paper aims to illustrate the achievements and the gaps in integration by demonstrating the trends in benefits available from the three social health insurance schemes, as well as the influencing factors. Data were drawn from the three waves of the China Health and Nutrition Survey (2009, 2011, 2015) undertaken since health reforms commenced. χ2, Kruskal-Wallis test, and the Two-Part model were employed in the analysis. The overall reimbursement rate of the Urban Employee Basic Medical Insurance (UEBMI) is higher than that of Urban Resident Basic Medical Insurance (URBMI) or the New Rural Cooperative Medical Scheme (NRCMS) (p < 0.001), but the gap has narrowed since health reform began in 2009. Both the outpatient and inpatient reimbursement amounts have increased through the URBMI and NRCMS. Illness severity, higher institutional level, and inpatient service were associated with significant increases in the amount of reimbursement received across the three survey waves. The health reform improved benefits covered by the URBMI and NRCMS, but gaps with the UEBMI still exist. The government should consider more the release of health benefits and how to lead toward healthcare equity.With the deepening of health insurance reform in China, the integration of social health insurance schemes was put on the agenda.

Barriers and facilitators to the implementation of digital technologies in mental health systems: a qualitative systematic review to inform a policy framework
Background
Despite the potential for improved population mental health and wellbeing, the integration of mental health digital interventions has been difficult to achieve. In this qualitative systematic review, we aimed to identify barriers and facilitators to the implementation of digital technologies in mental healthcare systems, and map these to an implementation framework to inform policy development.
Methods
We searched Medline, Embase, Scopus, PsycInfo, Web of Science, and Google Scholar for primary research articles published between January 2010 and 2022. Studies were considered eligible if they reported barriers and/or facilitators to the integration of any digital mental healthcare technologies. Data were extracted using EPPI-Reviewer Web and analysed thematically via inductive and deductive cycles.
Results
Of 12,525 references identified initially, 81 studies were included in the final analysis. Barriers and facilitators were grouped within an implementation (evidence-practice gap) framework across six domains, organised by four levels of mental healthcare systems. Broadly, implementation was hindered by the perception of digital technologies as impersonal tools that add additional burden of care onto both providers and patients, and change relational power asymmetries; an absence of resources; and regulatory complexities that impede access to universal coverage. Facilitators included person-cantered approaches that consider patients’ intersectional features e.g., gender, class, disability, illness severity; evidence-based training for providers; collaboration among colleagues; appropriate investment in human and financial resources; and policy reforms that tackle universal access to digital health.
Conclusion
It is important to consider the complex and interrelated nature of barriers across different domains and levels of the mental health system. To facilitate the equitable, sustainable, and long-term digital transition of mental health systems, policymakers should consider a systemic approach to collaboration between public and private sectors to inform evidence-based planning and strengthen mental health systems.

Medical Bankruptcy: Still Common Despite the Affordable Care Act
Myriad anecdotes—of a Nobel laureate who sold his medal to pay medical bills, or the more than 250 000 GoFundMe medical campaigns last year —attest to the financial toll of illness on American families. National surveys confirm that medical bills frequently cause financial hardship, and the US Consumer Financial Protection Bureau reported that they were by far the most common cause of unpaid bills sent to collection agencies in 2014, accounting for more than half of all such debts. Less evidence is available on the medical causes of bankruptcy, a public and stigmatizing confession of impoverishment. In surveys conducted by researchers with the Consumer Bankruptcy Project in 2001 and 2007, a majority of recently bankrupt debtors implicated medical bills or illness-related work loss as causes of their bankruptcy, findings that President Obama used to argue for passage of the Affordable Care Act (ACA). The ACA both expanded and upgraded health insurance coverage, banning preexisting illness exclusions, imposing a cap on out-of-pocket spending, and mandating coverage for essential benefits. Although these reforms might attenuate the risk of medical bankruptcy, increasing medical costs and stagnant incomes could have the opposite effect.
