Aims/hypothesisThe association between a history of hypertensive disorders of pregnancy (HDP) and subsequent type 2 diabetes (referred to throughout as diabetes) remains inconclusive. We reviewed the most recent evidence to quantify the association of previous HDP with incident diabetes.MethodsA systematic search of MEDLINE, Embase and CINAHL was performed up to 17 February 2020 to identify observational studies of the association between HDP (pre-eclampsia or gestational hypertension) and incident diabetes. Studies of women with pre-pregnancy diabetes were excluded. Two independent reviewers screened citations and abstracted results. Study quality was assessed in duplicate using the Newcastle–Ottawa Scale. Random-effects models were used to pool effect estimates. Heterogeneity was assessed using the I2 statistic.ResultsAfter screening 4617 citations, 16 cohort studies with a total of 3,095,457 participants were included (unspecified HDP n = 5, pre-eclampsia only n = 4, gestational hypertension and pre-eclampsia n = 7). Risks of subsequent diabetes were significantly higher in women with a history of any HDP (HDP: adjusted hazard ratio [aHR] 2.24, 95% CI 1.95, 2.58; gestational hypertension: aHR 2.19 [95% CI 1.69, 2.84]; pre-eclampsia: aHR 2.56 [95% CI 2.02, 3.24]; preterm pre-eclampsia: aHR 3.05 [95% CI 2.05, 4.56]). The association between HDP and diabetes persisted in studies that adjusted for gestational diabetes mellitus (aHR 2.01 [95% CI 1.77, 2.28]).Conclusions/interpretationHDP are independently associated with a higher risk of diabetes. Further study is needed to determine how HDP contribute to diabetes risk prediction to develop evidence-based screening and prevention strategies.

Aims/hypothesisDiabetes is associated with an increased incidence of colorectal cancer (CRC). There exists conflicting evidence regarding the impact of diabetes on CRC-specific mortality (herein also referred to as cancer-specific mortality). The objectives of this study were to determine whether diabetes is associated with a more advanced CRC stage at diagnosis and with higher all-cause and cancer-specific mortality.MethodsThis retrospective cohort study used linked, population-based health databases from Ontario, Canada. Among individuals diagnosed with CRC from 2007 to 2015, we compared the likelihood of presenting with later- (III or IV) vs early- (I or II) stage CRC between patients with and without diabetes adjusting for relevant covariates. We then determined the association between diabetes and all-cause and CRC-specific mortality, after adjusting for CRC stage at diagnosis and other covariates.ResultsOf the 44,178 individuals with CRC, 11,822 (26.7%) had diabetes. After adjustment for CRC screening and other covariates, individuals with diabetes were not more likely to present with later-stage CRC (adjusted OR 0.97, 95% CI 0.93, 1.01). Over a median follow-up of 2.63 (interquartile range [IQR] 0.97–5.10) years, diabetes was associated with higher all-cause mortality (adjusted HR 1.08, 95% CI 1.04, 1.12) but similar cancer-specific survival (adjusted HR 1.0, 95% CI 0.95, 1.06).Conclusions/interpretationIndividuals with diabetes who develop CRC are not more likely to present with a later stage of CRC and have similar cancer-specific mortality compared with those without diabetes. Diabetes was associated with higher all-cause mortality in CRC patients, indicating that greater attention to non-cancer care is needed for CRC survivors with diabetes.

Fecal occult blood tests (FOBT) are colorectal cancer screening tests used to identify individuals requiring further investigation with colonoscopy. Delayed colonoscopy after positive FOBT (FOBT+) is associated with poorer cancer outcomes. We assessed the effect of comorbidity on colonoscopy receipt within 12 months after FOBT+. Population-based healthcare databases from Ontario, Canada, were linked to assemble a cohort of 50-74-year-olds with FOBT+ results between 2008 and 2017. The associations between comorbidities and colonoscopy receipt within 12 months after FOBT+ were examined using multivariable cause-specific hazard regression models. Of 168,701 individuals with FOBT+, 80.5% received colonoscopy within 12 months. In multivariable models, renal failure (hazard ratio, HR 0.71, 95% confidence interval, CI 0.62 to 0.82), heart failure (HR 0.77, CI 0.75 to 0.80), and serious mental illness (HR 0.88, CI 0.85 to 0.92) were associated with the lowest colonoscopy rates, compared to not having each condition. The number of medical conditions was inversely associated with colonoscopy uptake (≥4 vs. 0: HR 0.64, CI 0.58 to 0.69; 3 vs. 0: HR 0.75, CI 0.72 to 0.78; 2 vs. 0: HR 0.87, CI 0.85 to 0.89). Having both medical and mental illness was associated with lower colonoscopy uptake relative to no comorbidity (HR 0.88, CI 0.87 to 0.90). Persons with medical and mental health conditions had lower colonoscopy rates after FOBT+ than those without these conditions. Better strategies are needed to optimize colorectal cancer screening and follow-up in individuals with comorbidities.

Introduction Universal health coverage (UHC) is an emerging priority of health systems worldwide and central to Sustainable Development Goal 3 (target 3.8). Critical to the achievement of UHC, is quality of care. However, current evidence suggests that quality of care is suboptimal, particularly in low- and middle-income countries. The primary objective of this scoping review was to summarize the existing conceptual and empirical literature on quality of care within the context of UHC and identify knowledge gaps. Methods We conducted a scoping review using the Arksey and O’Malley framework and further elaborated by Levac et al. and applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews reporting guidelines. We systematically searched MEDLINE, EMBASE, CINAHL-Plus, PAIS Index, ProQuest and PsycINFO for reviews published between 1 January 1995 and 27 September 2021. Reviews were eligible for inclusion if the article had a central focus on UHC and discussed quality of care. We did not apply any country-based restrictions. All screening, data extraction and analyses were completed by two reviewers. Results Of the 4128 database results, we included 45 studies that met the eligibility criteria, spanning multiple geographic regions. We synthesized and analysed our findings according to Kruk et al.’s conceptual framework for high-quality systems, including foundations, processes of care and quality impacts. Discussions of governance in relation to quality of care were discussed in a high number of studies. Studies that explored the efficiency of health systems and services were also highly represented in the included reviews. In contrast, we found that limited information was reported on health outcomes in relation to quality of care within the context of UHC. In addition, there was a global lack of evidence on measures of quality of care related to UHC, particularly country-specific measures and measures related to equity. Conclusion There is growing evidence on the relationship between quality of care and UHC, especially related to the governance and efficiency of healthcare services and systems. However, several knowledge gaps remain, particularly related to monitoring and evaluation, including of equity. Further research, evaluation and monitoring frameworks are required to strengthen the existing evidence base to improve UHC.

Introduction A large variation in diabetes prevalence by socioeconomic status (SES) persists internationally. This study aimed to quantify the prevalence of diabetes by age and SES and explore the current levels of inequality in the prevalence of diabetes in Ireland. Methods Annual cross-sectional self-reported diabetes data from the national population-based Healthy Ireland Survey for 2015–2023 ( n  = 59,933) were utilised. Highest educational attainment and area-based deprivation were used as SES indicators. Additionally, the differences in diabetes prevalence across population age-groups were reported. Socioeconomic differences and change in inequality over time were quantified using the relative index of inequality (RII). Logistic regression was used to estimate the relative risk (RR) for having self-reported diabetes according to age and SES, adjusted for sex and survey year. Results Diabetes prevalence was highest among individuals aged > 75 years (13.1%) compared to those aged < 40 years (1.0%). Similarly, prevalence was highest among the least educated (8.1%; RR = 2.73; 95% CI = 2.38, 3.13) compared to most educated (1.7%) and individuals living in most deprived areas (6.0%; RR = 2.18; 95% CI = 1.76, 2.70) compared to least deprived areas (2.2%). Additionally, the magnitude of relative inequalities as determined by education level were more than twofold greater than the magnitude of inequalities determined by area-based deprivation. Relative inequalities among individuals with diabetes persisted over the period 2015–2023 among the least educated (RII = 3.9; 95% CI = 3.3,4.6) and individuals living in the most deprived areas (RII = 3.65; 95% CI = 2.4,5.5). A slight increase in relative inequalities among the least educated, and a slight decline in relative inequalities among the most deprived was observed, however, these changes over time were not statistically significant. Conclusion This is the first study to examine the socioeconomic variation of diabetes prevalence at the Irish population level. Significant differences in diabetes prevalence persist. With the ageing Irish population, this study highlights the need to consider potential effects of diabetes across the older populations and the lowest socioeconomic status groups when implementing equity-oriented diabetes prevention and management programmes.

PurposeDiabetes is associated with poorer cancer outcomes. Screening for breast and cervical cancer is recommended by clinical guidelines; however, utilization of these tests in people with diabetes has been unclear due to methodological limitations in the evidence base. We used administrative data to determine the association between diabetes and the rates of becoming up-to-date with periodic breast and cervical cancer screening over a 20-year period.MethodsHealthcare databases from Ontario, Canada, were linked to assemble two population-based cohorts of 50–70 and 21–70 year-olds between 1994 and 2011, eligible for breast and cervical cancer screening, respectively. Using age as the time scale, multivariable recurrent events models were implemented to examine the association between the presence of diabetes and the rates of becoming up-to-date with the recommended cancer screenings.ResultsIn each of the breast and cervical cancer screening cohorts, there were, respectively, 1,516,302 (16% had diabetes at baseline) and 4,751,220 (9.5% had diabetes at baseline) screen-eligible women. In multivariable models, prevalent diabetes (duration ≥ 2 years) was associated with lower rates of becoming up-to-date with cervical (hazard ratio, HR 0.85, 95% confidence interval, CI 0.84–0.85) and breast (HR 0.94, CI 0.93–0.94) cancer screening, compared to no diabetes.ConclusionsHaving diabetes is associated with decreased rates of becoming up-to-date with two recommended periodic cancer screenings, with a bigger reduction in the rates of becoming up-to-date with cervical cancer screening. Greater attention to cervical cancer preventive services is needed in women with diabetes.

The procurement and provision of expert-driven, evidence-informed, and independent science advice is integral to timely decision-making during public health emergencies. The 2019 coronavirus disease (COVID-19) pandemic has underscored the need for sound evidence in public health policy and exposed the challenges facing government science advisory mechanisms. This paper is a jurisdictional case study describing (i) the federal science advice bodies and mechanisms for public health in Canada (i.e., the federal science advice “ecosystem”); and (ii) how these bodies and mechanisms have mobilized and evolved to procure expertise and evidence to inform decisions during the first two years of the COVID-19 pandemic. We reviewed publicly accessible Government of Canada documents, technical reports, and peer-reviewed articles available up to December 2021. Canada’s federal landscape of science advisory bodies for public health within the Health Portfolio was largely shaped by Canada’s experiences with the 2003 severe acute respiratory syndrome and 2009 H1N1 outbreaks. In parallel, Canada has a designated science advisory apparatus that has seen frequent reforms since the early 2000s, with the current Office of the Chief Science Advisor created within the Science Portfolio in 2018. The COVID-19 pandemic has further complicated Canada’s science advice ecosystem, with involvement from departments, expert advisory groups, and partnerships within both the federal Health and Science Portfolios. Although the engagement of federal departments outside the health sector is promising, the COVID-19 experience in Canada supports the need to institutionalize science advisory bodies for public health to improve pandemic preparedness and ensure rapid mobilization of well-coordinated and independent advice in future emergencies. This review also identified pressing areas for further inquiry to strengthen science advice for public health in Canada, including to assess the independence of science advisory actors and the interaction between federal and subnational authorities.

ObjectivesFinancial risk protection (FRP) is an indicator of the Sustainable Development Goal 3 universal health coverage (UHC) target. We sought to characterise what is known about FRP in the UHC context and to identify evidence gaps to prioritise in future research.DesignScoping overview of reviews using the Arksey & O’Malley and Levac & Colquhoun framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews reporting guidelines.Data sourcesMEDLINE, PsycINFO, CINAHL-Plus and PAIS Index were systematically searched for studies published between 1 January 1995 and 20 July 2021.Eligibility criteriaRecords were screened by two independent reviewers in duplicate using the following criteria: (1) literature review; (2) focus on UHC achievement through FRP; (3) English or French language; (4) published after 1995 and (5) peer-reviewed.Data extraction and synthesisTwo reviewers extracted data using a standard form and descriptive content analysis was performed to synthesise findings.Results50 studies were included. Most studies were systematic reviews focusing on low-income and middle-income countries. Study periods spanned 1990 and 2020. While FRP was recognised as a dimension of UHC, it was rarely defined as a concept. Out-of-pocket, catastrophic and impoverishing health expenditures were most commonly used to measure FRP. Pooling arrangements, expansion of insurance coverage and financial incentives were the main interventions for achieving FRP. Evidence gaps pertained to the effectiveness, cost-effectiveness and equity implications of efforts aimed at increasing FRP. Methodological gaps related to trade-offs between single-country and multicountry analyses; lack of process evaluations; inadequate mixed-methods evidence, disaggregated by relevant characteristics; lack of comparable and standardised measurement and short follow-up periods.ConclusionsThis scoping overview of reviews characterised what is known about FRP as a UHC dimension and found evidence gaps related to the effectiveness, cost-effectiveness and equity implications of FRP interventions. Theory-informed mixed-methods research using high-quality, longitudinal and disaggregated data is needed to address these objectives.

Background Humanitarian crises bring unique, and potentially growing challenges to people with type 1 diabetes (T1D). We aimed to determine, in youth with T1D (mean age (± 1SD) 0–17.9 years) within and coming from humanitarian crises settings (HCS), the reported prevalence that meet international consensus targets for glycaemic, blood pressure and lipid management, and incidence of severe hypoglycaemia or diabetic ketoacidosis. Methods A narrative review of quantitative data was conducted, using a systematic process. MEDLINE (Ovid), Global Health, Web of Science, Scopus, Embase, CINAHL, APA PsycINFO, Cochrane trials, and the reference lists of eligible records were searched (January 2014-February 2024); ten records covering ten separate studies were retrieved. Results Glycaemic management was consistently suboptimal in HCS. However, among individuals coming from HCS, glycaemia varied. Across both groups, data relating to blood pressure, lipids, severe hypoglycaemia or diabetic ketoacidosis were either unavailable or limited. Conclusion Findings expose the dearth of data relating to defined youth with T1D within and coming from HCS, leaving the status of this population largely uncharacterised. With limited data indicating suboptimal T1D management, there is a pressing need for the development of a consensus guideline on, and core indicators relating to such youth within and coming from HCS, plus monitoring systems and outcome data.

Objective: The study aims to investigate the patient perspective on the pathway from healthcare practitioners’ presentations of their cases at a Project ECHO (Extension for Community Healthcare Outcomes) tele-clinic to the management of those patients’ chronic pain. Introduction: Managing patients with chronic and complex pain constitutes a prevalent, stressful challenge in the primary care setting. Primary care physicians typically have received little training in treating such patients and, until recently, have relied heavily on opioid and other pharmaceutical therapies as part of their regimen. Project ECHO Ontario Chronic Pain and Opioid Stewardship is an interprofessional telementoring program connecting pain specialists to primary care practitioners with the aim of supporting them in managing their patients with chronic pain, although the patients concerned do not generally participate in the telementoring sessions. While a number of papers have described the benefits accruing to healthcare professionals through participating in Project ECHO, there has been little exploration concerning patients’ perceptions of their care subsequent to case presentation. Methods: Using data from in-depth interviews with 20 patients along with their associated case presentation forms and the recommendations following the presentation, we look at the alignment of patient and practitioner views and inquire about the patient’s perceptions of how Project ECHO affects them. Results: Results suggest that the impact on patients is indirect but positive: most respondents express pleasure in contributing to research around chronic pain management, though only two of them identified a direct impact on their own treatment. They also appreciated their practitioner’s efforts to bring expert attention to the patient’s situation. Conclusions: Patients whose cases are presented to Project ECHO sessions experience positive emotions at being part of the process of research and quality improvement, regardless of changes in their own conditions. This study highlights the importance to patients of their practitioners’ commitment to managing their chronic pain.
