Future leaders in a learning health system: Exploring the Health System Impact Fellowship.

The Canadian health system is reeling following the COVID-19 pandemic. Strains have become growing cracks, with long emergency department wait times, shortage of human health resources, and growing dissatisfaction from both clinicians and patients. To address long-needed health system reform in Canada, a modernization of training is required for the next generation health leaders. The Canadian Institutes of Health Research Health System Impact Fellowship (HSIF) is an example of a well-funded and connected training program which prioritizes embedded research and embedding technically trained scholars with health system partners. The program has been successful in the scope and impact of its training outcomes as well as providing health system partners with a pool of connected and capable scholars. Looking forward, integrating aspects of evidence synthesis from both domestic and international sources and adapting a general contractor approach to implementation within the HSIF could help catalyze learning health system reform in Canada.

Leading well and staying psychologically healthy: the role of resources and constraints for managers in the healthcare sector

PurposeMaintaining a healthy and productive workforce is a challenge for most organizations. This is even truer for health organization, facing staff shortages and work overload. The aim of this study is to identify the resources and constraints that influence managers' mental health and better understand how they are affected by them.Design/methodology/approachA qualitative approach was chosen to document the resources, the constraints as well as their consequences on managers in their day-to-day realities. The sample included executive-, intermediate- and first-level managers from a Canadian healthcare facility. A total of 62 semi-structured interviews were conducted. The coding process was based on the IGLOO model of Nielsen et al. (2018) to which an employee-related level was added (IGELOO).FindingsResults highlight the importance of considering both resources as well as constraints in examining managers' mental health. Overarching context, organizational constraints and the management of difficult employees played important roles in the stress experienced by managers.Practical implicationsThe results offer a better understanding of the importance of intervening at different levels to promote better organizational health. Results also highlight the importance of setting up organizational resources and act on the various constraints to reduce them. Different individual strategies used by managers to deal with the various constraints and maintain their mental health also emerge from those results.Originality/valueIn addition to addressing the reality of healthcare managers, this study supplements a theoretical model and suggests avenues for interventions promoting more sustainable organizational health.

Access to Healthcare and Unmet Needs in the Canadian Lesbian-Gay-Bisexual Population

ABSTRACT Individuals who identify as a sexual minority, including those who are lesbian, gay, or bisexual (LGB), face barriers to healthcare as well as increased discrimination, stigmatization, and negative experiences during healthcare use. Further, few healthcare providers have education and training focused on the specific healthcare needs of individuals who are part of a sexual minority group. Given the limited research on Canadian healthcare access for sexual minorities, our purpose was to use data (n > 2,800) from the 2015–16 Canadian Community Health Survey (CCHS) to investigate the perceptions of healthcare access for LGB and non-LGB Canadians. Although non-LGB and LGB participants reported comparable access to a regular care provider and were equally likely to have consulted with a general practitioner in the past 12 months, LGB respondents were more likely to have seen a specialist and reported more unmet health needs. Although we expected the linear effects of both race and sex to vary by LGB status, this effect only occurred in one model. Current results have implications for addressing health inequalities for sexual minorities, including poorer health outcomes and greater discrimination.

The Cost-Effectiveness of First-Line Cryoablation vs First-Line Antiarrhythmic Drugs in Canadian Patients With Paroxysmal Atrial Fibrillation

BackgroundThe EARLY-AF (NCT02825979), STOP AF First (NCT03118518), and Cryo-FIRST (NCT01803438) randomised controlled trials (RCTs) demonstrated that cryoballoon pulmonary vein isolation reduces atrial fibrillation (AF) recurrence compared with antiarrhythmic drugs (AADs) in patients with symptomatic paroxysmal atrial fibrillation (PAF). The present study developed a cost-effectiveness model (CEM) of first-line cryoablation compared with first-line AADs for PAF, from the Canadian health care payer’s perspective. MethodsData from the 3 RCTs were analysed to estimate key CEM parameters. The model structure used a decision tree for the first 12 months and a Markov model with a 3-month cycle length for the remaining lifetime time horizon. Costs were set at 2023 Canadian dollars, health benefits were expressed as quality-adjusted life years (QALYs), and both were discounted 3% annually. Probabilistic sensitivity analysis (PSA) considered parameter uncertainty. ResultsThe statistical analysis estimated that first-line cryoablation generates a 47% reduction (P < 0.001) in the rate of AF recurrence, a 73% reduction in the rate of subsequent ablation (P < 0.001), and a 4.3% (P = 0.025) increase in health-related quality of life, compared with first-line AADs. The PSA indicates that an individual treated with first-line cryoablation accrues less costs (−$3,862) and more QALYs (0.19) compared with first-line AADs. Cryoablation is cost-saving in 98.4% of PSA iterations and has a 99.9% probability of being cost-effective at a cost-effectiveness threshold of $50,000 per QALY gained. Cost-effectiveness results were robust to changes in key model parameters. ConclusionsFirst-line cryoballoon ablation is cost-effective when compared with AADs for patients with symptomatic PAF.

Healthcare costs and effects of post-COVID-19 condition in Canada.

As evidence of the long-term health impacts of coronavirus disease 2019 (COVID-19) continues to grow across Canada, a key concern is the costs and health impacts of post-COVID-19 condition (PCC), especially while the healthcare system remains under substantial strain. The objective of this study is to estimate healthcare costs and quality-adjusted life year (QALY) decrements per PCC case and per acute COVID-19 case by vaccination status. First, we conducted a rapid review of the literature to estimate 1) the probability of developing PCC following COVID-19 infection by vaccination status, 2) the probability of each condition commonly associated with PCC, 3) healthcare costs and QALY decrements associated with each condition and 4) the number of PCC cases currently in Canada. Second, using the data gathered from the literature, we built a tool to estimate the cost and QALY decrements per PCC and COVID-19 case. Post-COVID-19 condition costs per COVID-19 case ranged from CAD 1,675 to CAD 7,340, and QALY decrements ranged between 0.047 to 0.206, in the first year following COVID-19 infection. Overall, individuals who were unvaccinated when they were infected had higher costs and QALY decrements. We estimated the total burden of PCC to the Canadian healthcare system based on PCC estimates up until spring 2023 would be between CAD 7.8 and CAD 50.6 billion. This article demonstrates the large potential health and economic burden of PCC for Canadians, and the importance of vaccination and other infection control strategies in reducing the longer-term costs and effects.

Strengthening health system leadership in practice.

The field of health leadership is shifting rapidly, and there is an opportunity to learn with health leaders about what is needed to support health leadership education, research, and practice. In 2022, to augment student feedback and faculty praxis, Royal Roads University conducted 12 virtual interviews with senior health system leaders across various settings to learn how health leaders can better respond to emerging and future leadership needs and priorities facing health systems. Findings from this study informed the development of a health-specific elective for the Master of Arts in Leadership, Health Specialization program entitled Considerations for Health Systems Renewal. This elective explores the following topics that emerged from this research study: (1) an orientation to possibility; (2) emerging strategic human resource concerns; (3) healthcare innovation; (4) relational and social systems leadership; (5) polarity thinking; (6) trauma-informed leadership; and (7) Canadian healthcare networks. In this article, we share our research process and findings to arrive at these recommendations.

Shaping Social Media: Is Twitter an Equitable tool for Professional Development?

Twitter has become a powerful tool for professional development in academia. However, studies from the general population suggest that racialized and gender biases disproportionately empower male and white users. We characterized the demographics of Twitter influencers in Canadian healthcare. We used the Right Relevance Insight API algorithm to identify Twitter influencers in the healthcare, healthcare research, and health policy domains, and to generated normalized influencer scores based on user connections and engagement. We used facial recognition software to approximate the influencers' race and sex. The majority of influencers identified were white (84%) and/or male (60%). Males had significantly higher influencer scores than females (65.1 ± 8.0 vs. 61.2 ± 6.2, P < 0.05) in health policy. We did not identify any sex- or race-associated disparities among influencers in healthcare or healthcare research. Male users have significantly higher levels of influence in health policy on Twitter. Given the importance of Twitter as a tool for professional development, it is crucial that institutional leaders and policymakers are aware of potential inequities in user reach. Future studies should evaluate additional factors shaping user influence in healthcare on Twitter, with a focus on equity, diversity, and trustworthiness.

Drawing Insights from the COVID-19 Pandemic

The COVID-19 pandemic presented an array of challenges, characterized by its unpredictability and rapidly changing nature. While often referred to as an "unprecedented" crisis, it is important to recognize the shared traits it possesses with previous pandemics. To fortify our society against future outbreaks, continued investment in pandemic preparedness is essential. This paper aims to extract valuable insights from four crucial sectors within Canada's healthcare system during the COVID-19 pandemic. The identified areas of focus include: 1) Addressing the "disinfodemic" by effectively countering the dissemination of misinformation; 2) Promoting justice in resource allocation to ensure fairness and equity; 3) Strengthening healthcare infrastructure to meet the demands of resource-intensive crises like COVID-19; and 4) Mitigating the long-term impact of stringent pandemic-related restrictions. Through an honest reflection on these key sectors, this paper sheds light on crucial lessons learned and paves the way for robust preparedness strategies for future outbreaks.

Risk stratification for treating people at ultra-high risk for psychosis: A cost-effectiveness analysis.

People who are at ultra-high risk (UHR) for psychosis receive clinical care with the aim to prevent first-episode psychosis (FEP), regardless of the risk of conversion to psychosis. An economic model from the Canadian health system perspective was developed to evaluate the cost-effectiveness of treating all with UHR compared to risk stratification over a 15-year time horizon, based on conversion probability, expected quality-of-life and costs. The analysis used a decision tree followed by a Markov model. Health states included: Not UHR, UHR with <20% risk of conversion to FEP (based on the North American Prodrome Longitudinal Study risk calculator), UHR with ≥20% risk, FEP, Remission, Post-FEP, and Death. The analysis found that: risk stratification (i.e., only treating those with ≥20% risk) had lower costs ($1398) and quality-adjusted life-years (0.055 QALYs) per person compared to treating all. The incremental cost-effectiveness ratio for 'treat all' was $25,448/QALY, and suggests treating all may be cost-effective. The model was sensitive to changes to the probability of conversion.

Cohort profile: recruitment and retention in a prospective cohort of Canadian healthcare workers during the COVID-19 pandemic

MLH1 Methylation Testing as an Integral Component of Universal Endometrial Cancer Screening-A Critical Appraisal.

MLH1/PMS2 loss due to MLH1 promoter hypermethylation (MLH1-PHM) is the most common cause of mismatch repair (MMR) deficiency in endometrial cancer (EC). This study aimed to determine the proportion of MLH1-deficient EC with PHM, assess the impact of the reflex MLH1-PHM testing strategy, and evaluate the associated costs within the publicly funded Canadian healthcare system. In a cohort of 2504 EC samples, 534 (21.4%) exhibited dual MLH1/PMS2 loss, prompting MLH1-PHM testing. Among 418 cases with available testing results, 404 (96.7%) were MLH1-hypermethylated, while 14 (3.3%) were non-methylated. The incidence of MLH1 non-methylated cases in our cohort was 14/2504 (0.56%) of all ECs, underscoring the prevalence of hypermethylation-driven MLH1/PMS2 loss in ECs universally screened for MMR deficiency. Reflex MLH1-PHM testing incurs substantial costs and resource utilization. Assay cost is CAD 231.90 per case, amounting to CAD 123,834.60 for 534 cases, with 30 tests needed per additional candidate for MLH1 germline analysis (CAD 6957.00 per candidate). This raises a provocative question: can we assume that the majority of the MLH1-deficient ECs are due to PHM and forgo further testing in healthcare systems with finite resources? It is imperative to assess resource utilization efficiency and explore optimized approaches that encompass clinical correlation, family history and judicious utilization of methylation testing to ensure it is provided only to those who stand to benefit from it.

Internal versus external knowledge sourcing of organizational rules: an exploratory study of CPGs in a healthcare organization

Abstract In this study, we examine how organizational rules source knowledge. By knowledge sourcing of a rule, we mean the formation of reference ties from the rule to knowledge sources located outside of the focal rule. Rules can source knowledge from sources within the organization (e.g., other rules) and outside (e.g., research publications, policies, standards, etc.). Our theoretical model proposes that knowledge sourcing of rules is driven by inherent incompleteness of rules as a result of bounded rationality of rule makers and rule making process. Incomplete rules can lead to experiences of insufficient rule knowledge, termed “knowledge gaps,” which are shaped by rule dynamics at the levels of individual rules, the rule system, and rule networks. Our theoretical model leads to several hypotheses that we test with longitudinal archival data of clinical practice guideline (CPG) changes in a Canadian healthcare organization. The findings support our theoretical model of incomplete organizational rules which encounter knowledge gaps and close them through internal and external knowledge sourcing. The theoretical and practical implications of the findings are discussed.

Specialty Care and Counselling about Hereditary Cancer Risk Improves Adherence to Cancer Screening and Prevention in Newfoundland and Labrador Patients with BRCA1/2 Pathogenic Variants: A Population-Based Retrospective Cohort Study.

Pathogenic variants (PVs) in BRCA1 and BRCA2 increase the lifetime risks of breast and ovarian cancer. Guidelines recommend breast screening (magnetic resonance imaging (MRI) and mammogram) or risk-reducing mastectomy (RRM) and salpingo-oophorectomy (RRSO). We sought to (1) characterize the population of BRCA1/2 PV carriers in Newfoundland and Labrador (NL), (2) evaluate risk-reducing interventions, and (3) identify factors influencing screening and prevention adherence. We conducted a retrospective study from a population-based provincial cohort of BRCA1/2 PV carriers. The eligibility criteria for risk-reducing interventions were defined for each case and patients were categorized based on their level of adherence with recommendations. Chi-squared and regression analyses were used to determine which factors influenced uptake and level of adherence. A total of 276 BRCA1/2 PV carriers were identified; 156 living NL biological females composed the study population. Unaffected females were younger at testing than those with a cancer diagnosis (44.4 years versus 51.7 years; p = 0.002). Categorized by eligibility, 61.0%, 61.6%, 39.0%, and 75.7% of patients underwent MRI, mammogram, RRM, and RRSO, respectively. Individuals with breast cancer were more likely to have RRM (64.7% versus 35.3%; p < 0.001), and those who attended a specialty hereditary cancer clinic were more likely to be adherent to recommendations (73.2% versus 13.4%; p < 0.001) and to undergo RRSO (84.1% versus 15.9%; p < 0.001). Nearly 40% of the female BRCA1/2 PV carriers were not receiving breast surveillance according to evidence-based recommendations. Cancer risk reduction and uptake of breast imaging and prophylactic surgeries are significantly higher in patients who receive dedicated specialty care. Organized hereditary cancer prevention programs will be a valuable component of Canadian healthcare systems and have the potential to reduce the burden of disease countrywide.

Patient and Provider Gender and Kidney Transplant Referral in Canada: A Survey of Canadian Healthcare Providers.

Referral for kidney transplant (KT) is variable, with women often disadvantaged. This study aimed to better characterize Canadian transplant referral practices and identify potential differences by respondent and/or patient gender using surveys targeted at healthcare practitioners (HCPs) involved in KT. Surveys consisting of 25 complex patient cases representing 7 themes were distributed to KT HCPs across Canada (March 3, 2022-April 27, 2022) using national nephrology/transplant society email registries. Respondents were asked whether they would refer the patient for transplant. Two identical surveys were created, differing only by gender/gender pronouns used in each case. Multivariable logistic regression was used to assess the association of respondent demographics and patient themes (including case gender) with the odds of transplant referral (overall and stratifying by respondent gender). Overall, the referral rate was 58.0% among 97 survey respondents (46.4% male). Case themes associated with a lower likelihood of referral included adherence concerns (adjusted odds ratio [aOR] 0.65; 95% confidence interval [CI], 0.45-0.94), medical complexity (aOR 0.57; 95% CI, 0.38-0.85), and perceived frailty (aOR 0.63; 95% CI, 0.47-0.84). Respondent gender was not associated with differences in KT referral (aOR 0.91; 95% CI, 0.65-1.26 for male versus female respondents) but modified the association of frailty (less referral for male than female respondents, P = 0.005) and medical complexity (less referral for female than male respondents, P = 0.009) with referral. There were no differences in referral rate by case gender ( P = 0.82). KT referral practices vary among Canadian HCPs. In this study, there were no differences in likelihood of transplant referral by candidate gender.

Revolutionising Cancer Diagnosis and Treatment: A Review on Advancements in Nanomaterial-based Theranostics

The persistent struggle against cancer has given rise to the development of nanotheranostics, a domain that integrates therapeutic and diagnostic capabilities within nanoscale structures. This paper explores advancements in nanomaterials and nanoparticles for cancer nanotheranostics, focusing on their design, significance, and applications. The incorporation of biocompatible nanoparticles in cancer therapy offers personalised, targeted approaches while minimising side effects. The use of nanomaterials such as metals, polymers, and lipids enable precise drug delivery and imaging. Various imaging modalities, including ultrasound and fluorescence, complement therapeutic strategies for enhanced precision. Critical parameters for nanomaterial selection and design are discussed, emphasising biocompatibility, targeting efficiency, and drug delivery capacity. Biocompatibility ensures safe interactions within biological systems, requiring mitigation of toxicological concerns through strategies like anti-inflammatory peptides or ligand-functionalization. Targeting efficiency combines passive and active targeting to enhance specificity, reshaping cancer diagnostics and therapy. Drug delivery capacity is achieved through engineered core-shell structures with distinct properties, including liposomes, micelles, and dendrimers, each tailored for targeted therapy and imaging. This paper also discusses the advancements in the field of cancer treatment using nanotheranostics and its economic impact on the Canadian healthcare systems while following the ethical guidelines towards patients’ consent, privacy, and the proper use of emerging technologies.

Real-world practices for the care of women with epilepsy during pregnancy: A Canadian perspective

ObjectiveApproximately 150,000 Canadian women live with epilepsy, a population that presents with unique challenges. Our objective was to capture demographic and real-world practice characteristics of Canadian healthcare professionals providing care for women with epilepsy (WWE) with specific focus on reproductive considerations to identify potential gaps in knowledge and care. MethodsA questionnaire developed by the Canadian League Against Epilepsy WWE workgroup was distributed to Canadian healthcare professionals from February 2021 to October 2022 to capture participant demographic characteristics and practice patterns in key areas of the reproductive cycle in WWE. ResultsA total of 156 participants completed the questionnaire, most being physicians (81.4%), epilepsy specialists (69.0%), and those who cared for adult patients (86.5%), with a significant proportion based at an academic center (65.4%). The majority of participants counselled on folic acid supplementation (89.7%). Participants selected lamotrigine and levetiracetam most frequently for either focal or generalized epilepsies during pregnancy. Additionally, 85.9% performed therapeutic drug monitoring during pregnancy. Almost all practitioners always or often counseled WWE on valproic acid on the benefits of switching to a less teratogenic medication (96.2%). Some geographic variability in practice patterns was noted with valproic acid being one of the top three medications selected for patients with generalized epilepsies in Western regions, although participants in Eastern regions had brivaracetam more commonly included as one of their top three agents for this population. SignificanceThis is the first report of real-world Canadian practices in epilepsy care for women in pregnancy. Overall, our study reports that Canadian practice patterns conform well to current evidence and best-practice guidelines. Important variations in antiseizure medication selection across different regions were identified.

"I Get It, I'm Sick Too": An Autoethnographic Study of One Researcher/Practitioner/Patient With Chronic Illness.

This autoethnographic research utilizes reflexivity as a method to explore my self-experience of Lyme disease while holding co-occurring identities as a researcher, health professional, and mother. Awareness of self is central in psychotherapy so that therapists do not adversely impact their clients. This is similar for researchers who are ethically required to acknowledge and reduce any potential risk(s) of harm to their participants. In this study, I describe and systematically analyze my experiences as a patient with symptom-persistent Lyme disease, contextualized through co-occurring identities as a mother, a regulated (mental) health professional, and a scholar investigating the embodied experience of being a Lyme disease patient in the Canadian context. The central research question guiding this study is: "What are my experiences with symptom-persistent Lyme disease?" The results of this study suggest reflexivity is an important practice in both health research and healthcare. Relationships with health professionals have a significant impact on patients' healthcare experiences, and engaging in reflexive practice may improve the responsivity of healthcare professionals toward patients' needs and embodied experiences and serve as a check on pre-existing power relations in healthcare. Further, this research contributes to the current academic knowledge on symptom-persistent Lyme disease by offering a reflexive representation of my experiences as a researcher who is also a health professional and a patient within the Canadian healthcare system. Representations of patients' experiences are critical in advancing health research and ensuring equitable care for patients. Autoethnography offers important insights into patients' disease experiences.

Clinical practice guideline for management of osteoporosis and fracture prevention in Canada: 2023 update.

In Canada, more than 2 million people live with osteoporosis, a disease that increases the risk for fractures, which result in excess mortality and morbidity, decreased quality of life and loss of autonomy. This guideline update is intended to assist Canadian health care professionals in the delivery of care to optimize skeletal health and prevent fractures in postmenopausal females and in males aged 50 years and older. This guideline is an update of the 2010 Osteoporosis Canada clinical practice guideline on the diagnosis and management of osteoporosis in Canada. We followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework and quality assurance as per Appraisal of Guidelines for Research and Evaluation (AGREE II) quality and reporting standards. Primary care physicians and patient partners were represented at all levels of the guideline committees and groups, and participated throughout the entire process to ensure relevance to target users. The process for managing competing interests was developed before and continued throughout the guideline development, informed by the Guideline International Network principles. We considered benefits and harms, patient values and preferences, resources, equity, acceptability and feasibility when developing recommendations; the strength of each recommendation was assigned according to the GRADE framework. The 25 recommendations and 10 good practice statements are grouped under the sections of exercise, nutrition, fracture risk assessment and treatment initiation, pharmacologic interventions, duration and sequence of therapy, and monitoring. The management of osteoporosis should be guided by the patient's risk of fracture, based on clinical assessment and using a validated fracture risk assessment tool. Exercise, nutrition and pharmacotherapy are key elements of the management strategy for fracture prevention and should be individualized. The aim of this guideline is to empower health care professionals and patients to have meaningful discussions on the importance of skeletal health and fracture risk throughout older adulthood. Identification and appropriate management of skeletal fragility can reduce fractures, and preserve mobility, autonomy and quality of life.

Anti-Black racism: Gaining insight into the experiences of Black nurses in Canada.

The call to address anti-Black racism in workplaces resonates across several organizations and institutions in Canada. But specifically, the coronavirus disease 2019 pandemic shed further light on how health inequities negatively impact the Black community. After conducting a literature review of the experiences of Black nurses in Canada, a deeper understanding of their plight was gained. In healthcare, the findings from the Black Nurses'Task Force report conclude that anti-Black racist practices are pervasive in nursing, and there remains a paucity of research in this area. This study builds off the report by exploring how Black nurses experience anti-Black racism while working in Canada's healthcare system. Inspired by critical race theory and Black feminist thought, an exploratory qualitative research study was conducted, using semistructured interviews to gather data. The study concludes that Black nurses experience anti-Black racism within the workplace, and it manifests itself through some of the attitudes of colleagues, patients, and nurses in leadership roles. Despite policies and statements that were in place to protect them, anti-Black racism continues to occur systematically. The findings point to the need for change in the overall workplace culture, which includes a fair representation of Black nurses in leadership roles, further research to identify best practices for tackling anti-Black racism within Canada's healthcare system, and mandatory training on anti-Black racism for healthcare leaders, educators, and service providers.
