The role of C4d and donor specific antibodies in face and hand transplantation-a systematic review.

To date, little is known about the mechanisms of rejection in vascularized composite allotransplantation, particularly for antibody mediated rejection. Additionally, no clear guidelines exist for the diagnosis and management of antibody-mediated rejection in vascularized composite allotransplantation. A systematic review of electronic databases (Embase and PubMed) was conducted to evaluate the relationship of donor specific antibodies and C4d deposition in correlation with cellular rejection following hand and face transplantation reported by centers between 1998 and July 2023. We extracted data on serum donor specific antibodies at the time of biopsy proven rejection according to Banff classification and C4d staining of target tissues. Mann-Whitney U tests were performed to compare rejection grade between groups divided by status of C4d deposition and serum donor specific antibodies, and Fisher's Exact test was used to assess association between the two markers. This review adhered to PRISMA guidelines. A total of 26 patients (5 face, 21 hand) were identified and data on 90 acute rejection episodes with information on Banff grade, donor specific antibody status, and C4d deposition were available. Donor specific antibodies were found to be associated with higher rejection grade (p = 0.005). C4d was not found to be associated with higher rejection grade (p = 0.33). Finally, no significant association was found between concurrent status of the two markers (p = 0.23). These findings suggest that the presence of donor specifc antibodies may be associated with higher grades of acute cellular rejection following hand and face transplantation. More consistent reporting on rejection episodes is needed in order to better understand antibody-mediated rejection in vascularized composite allotransplantation.

Summary statistics knockoffs inference with family-wise error rate control.

Testing multiple hypotheses of conditional independence with provable error rate control is a fundamental problem with various applications. To infer conditional independence with family-wise error rate (FWER) control when only summary statistics of marginal dependence are accessible, we adopt GhostKnockoff to directly generate knockoff copies of summary statistics and propose a new filter to select features conditionally dependent on the response. In addition, we develop a computationally efficient algorithm to greatly reduce the computational cost of knockoff copies generation without sacrificing power and FWER control. Experiments on simulated data and a real dataset of Alzheimer's disease genetics demonstrate the advantage of the proposed method over existing alternatives in both statistical power and computational efficiency.

Patient, family and caregiver engagement in diabetes care: a scoping review protocol.

INTRODUCTION: New treatments and technologies have advanced diabetes care; however, diabetes continues to have a major impact on the daily lives of affected individuals, especially among equity-deserving groups. Evidence from patient engagement literature suggests that involving diverse patients in healthcare can create cost-effective improvements and enhanced efficiency in care that has high patient acceptability and numerous health benefits, as well as improved provider satisfaction. A scoping review will be conducted to provide a cohesive and comprehensive understanding of patient engagement practices and the resulting outcomes. METHODS AND ANALYSIS: The review will follow the recommendations for the conduct of scoping reviews developed by the Joanna Briggs Institute (JBI) Scoping Review Methodology Group. The review will include English-language literature published between 1 January 1990 and the present, searched through MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), International Bibliography of the Social Sciences (IBSS), Sociological Abstracts, Applied Social Sciences Index and Abstracts (ASSIA), Scopus, Social Sciences Citation Index and Campbell Collaboration; hand searches; and grey literature. Literature that describes conceptualisations of engagement, methods/strategies for engagement and/or evaluations of engagement across different levels of diabetes care, including direct care, organisational design and governance and policymaking will be included. The review will encompass quantitative, qualitative and mixed-methods studies. Research that is secondary, published in languages other than English, or not specifically focused on patient engagement will be excluded. Screening and extraction will be completed by two independent reviewers and conflicts will be resolved by discussion or a third reviewer, with piloting at each step. Studies will be analysed through descriptive numerical summary and content analysis. ETHICS AND DISSEMINATION: No ethical or safety considerations are pertinent to this work. The results will be disseminated to patients/patient advocacy groups, diabetes organisations, clinicians, researchers, decision-makers and policymakers by way of summary documents, infographics, meeting presentations and through peer-reviewed publications. TRIAL REGISTRATION NUMBER: The protocol has been registered with Open Science Framework: https://doi.org/10.17605/OSF.IO/KCD7Z.

Engagement with partners is a leading practice in health workforce planning: What health leaders need to know.

Workforce planning ensures that the health workforce is aligned with current and future population needs. Engagement with partners and knowledge users is a leading practice in planning and is essential for planning to be successful. The goal of this study was to explore the considerations and processes involved in integrating engagement into workforce planning. Through a case study of primary care workforce planning in Toronto, we address the role of engagement, how it can be integrated into planning, and how lessons from engagement support spread and scale of effective workforce planning. In the course of engagement with five Ontario Health Teams between September 2023 and February 2024, we learned that there is considerable enthusiasm for planning, but that support is needed, and that engagement guides investment and strengthens relationships. We offer guidance for leaders with respect to actualizing engagement and building capacity for health workforce planning across the health system.

"The straw that broke the camel's back": An analysis of racialized women clinicians' experiences providing diabetes care.

INTRODUCTION: Racialized women clinicians (RWCs) experience the brunt of unfair racial and gendered expectations, which is a direct result of their visible identity. Our study sought to understand how these experiences intersect to impact the personal and professional well-being of RWCs, and their approach to diabetes care. METHODS: Data were collected from 24 RWCs working within Canadian diabetes care settings, who participated in semi-structured, one-on-one interviews conducted from April 2021 to September 2021. The data were qualitatively analyzed using thematic analysis to develop emergent themes, and interactions were explored using the socioecological model (SEM), adapted to our study context. RESULTS: We identified three themes: (1) Discordance between self-identity and relational identity impacted how RWCs interacted with others, and how others interacted with them; (2) Tokenistic, "inclusive" organizational policies/practices and inherently racist and sexist social norms permitted acts of discrimination and led to the systematic othering and exclusion of RWCs within the workplace; and (3) Differential treatment of RWCs had both positive and negative impacts on participants' relational, workplace and self-identity. Using the SEM, we also found that differential treatment of RWCs stems from upstream policies, structures, and social norms, percolating through different levels of the SEM, including work environments and communities, which eventually impacts one's relational identity, as well as one's perception of oneself. CONCLUSION: The differential treatment of RWCs arises predominantly from macro systems of the work environment. The burden to address these disparities must be shifted to the source (i.e., namely systems) by implementing interventions that equitably value diversity efforts, institute policies of accountability and correction of implicit biases, and prioritize an inclusive culture broadly across faculty and leadership.

New Kid on the Block: A Systematic Review of the Quadratus Lumborum Block in Plastic and Reconstructive Surgery.

Background: Although the transversus abdominal plane (TAP) block is commonly used in abdominal surgery as part of enhanced recovery after surgery pathways, the quadratus lumborum (QL) block has been hypothesized as an effective alternative to the TAP block in some areas. This review evaluates the current literature, as it relates to the QL block in plastic and reconstructive surgery. Methods: A systematic review using PubMed searched for all original, peer-reviewed articles, including the term "quadratus lumborum block." In total, 509 articles were identified for review by two independent reviewers. Original articles evaluating the use of a QL block in any plastic surgery operation were included. Articles evaluating pediatric patients, animal trials, and the use of a QL block in any nonplastic surgery operation were excluded. Results: Three articles met inclusion criteria. One trial demonstrated decreased subjective pain scores and total opioid use, whereas the second found no statistically significant difference. A case study described the use of a QL block for unilateral breast reconstruction with minimal opiate use and reduced pain scores postoperatively. Limitations include the limited number of studies and the heterogeneity in study type and design, making analysis difficult. Conclusions: Despite its demonstrated efficacy in other surgical subspecialties, there are limited data evaluating the use of the QL block in plastic and reconstructive surgery. Additional research is needed to evaluate the role of the QL block in plastic surgery and how it compares to the more widely utilized TAP block.

Preclinical Performance of the Combined Application of Two Robotic Systems in Microsurgery: A Two-center Study.

Background: Recent advancements in the development of robotic devices increasingly draw the attention toward the concept of robotic microsurgery, as several systems tailored to open microsurgery are being introduced. This study describes the combined application of a novel microsurgical robot, the Symani, with a novel robotic microscope, the RoboticScope, for the performance of microvascular anastomoses in a two-center preclinical trial. Methods: Six novices, residents, and experienced microsurgeons (n = 18) performed five anastomoses on 1.0-mm-diameter silicone vessels with a conventional versus combined robotic approach, resulting in 180 anastomoses. Microsurgical performance was evaluated, analyzing surgical time, subjective satisfaction with the anastomosis and robotic setup, anastomosis quality using the anastomosis lapse index score, microsurgical skills using the Structured Assessment of Microsurgery Skills score, and surgical ergonomics using the Rapid Entire Body Assessment score. Results: All participants significantly improved their performance during the trial and quickly adapted to the novel systems. Surgical time significantly decreased, whereas satisfaction with the anastomosis and setup improved over time. The use of robotic systems was associated with fewer microsurgical errors and enhanced anastomosis quality. Especially novices demonstrated accelerated skill acquisition upon robotic assistance compared with conventional microsurgery. Moreover, upper extremity positioning was significantly improved. Overall, the robotic approach was subjectively preferred by participants. Conclusions: The concept of robotic microsurgery holds great potential to improve precision and ergonomics in microsurgery. This two-center trial provides promising evidence for a steep learning curve upon introduction of robotic microsurgery systems, suggesting further pursuit of their clinical integration.

Optimizing a mentorship program from the perspective of academic medicine leadership - a qualitative study.

BACKGROUND: Effective mentorship is an important contributor to academic success. Given the critical role of leadership in fostering mentorship, this study sought to explore the perspectives of departmental leadership regarding 1) current departmental mentorship processes; and 2) crucial components of a mentorship program that would enhance the effectiveness of mentorship. METHODS: Department Division Directors (DDDs), Vice-Chairs, and Mentorship Facilitators from the Department of Medicine at the University of Toronto Temerty Faculty of Medicine were interviewed between April and December 2021 using a semi-structured guide. Interviews were audio-recorded and transcribed verbatim, then coded. Analysis occurred in 2 steps: 1) codes were organized to identify emergent themes; then 2) the Social Ecological Model (SEM) was applied to interpret the findings. RESULTS: Nineteen interviews (14 DDDs, 3 Vice-Chairs, and 2 Mentorship Facilitator) were completed. Analysis revealed three themes: (1) a culture of mentorship permeated the department as evidenced by rigorous mentorship processes, divisional mentorship innovations, and faculty that were keen to mentor; (2) barriers to the establishment of effective mentoring relationships existed at 3 levels: departmental, interpersonal (mentee-mentor relationships), and mentee; and (3) strengthening the culture of mentorship could entail scaling up pre-existing mentorship processes and promoting faculty engagement. Application of SEM highlighted critical program features and determined that two components of interventions (creating tools to measure mentorship outcomes and systems for mentor recognition) were potential enablers of success. CONCLUSIONS: Establishing 'mentorship outcome measures' can incentivize and maintain relationships. By tangibly delineating departmental expectations for mentorship and creating systems that recognize mentors, these measures can contribute to a culture of mentorship.

Transgender health objectives of training for adult Endocrinology and Metabolism programs: Outcomes of a modified-Delphi study.

BACKGROUND: Transgender people encounter significant barriers when seeking timely, high-quality healthcare, resulting in unmet medical needs with increased rates of diabetes, asthma, chronic obstructive pulmonary disease, and HIV. The paucity of postgraduate medical education to invest in standardization of transgender health training sustains these barriers, leaving physicians feeling unprepared and averse to provide transgender health care. Closing this education gap and improving transgender healthcare necessitates the development of consensus-built transgender health objectives of training (THOOT), particularly in Adult Endocrinology and Metabolism Residency programs. METHODS: We conducted a two-round modified-Delphi process involving a nationally representative panel of experts, including Adult Endocrinology and Metabolism program directors, physician content experts, residents, and transgender community members, to identify THOOT for inclusion in Canadian Endocrinology and Metabolism Residency programs. Participants used a 5-point Likert scale to assess THOOT importance for curricular inclusion, with opportunities for written feedback. Data was collected through Qualtrics and analyzed after each round. FINDINGS: In the first Delphi round, panelists reviewed and rated 81 literature extracted THOOT, achieving consensus on all objectives. Following panelists' feedback, 5 THOOT were added, 9 removed, 34 consolidated into 12 objectives, and 47 were rephrased or retained. In the second Delphi round, panelists assessed 55 THOOT. Consensus was established for 8 THOOT. Program directors' post-Delphi feedback further consolidated objectives to arrive at 4 THOOT for curriculum inclusion. CONCLUSIONS: To our knowledge, this is the first time a consensus-based approach has been used to establish THOOT for any subspecialty postgraduate medicine program across Canada or the United States. Our results lay the foundation towards health equity and social justice in transgender health medical education, offering a blueprint for future innovations.

Risk-Tailoring Radiotherapy for Endometrial Cancer: A Narrative Review.

Endometrial cancer is the most common gynecologic cancer in the United States and it contributes to the second most gynecologic cancer-related deaths. With upfront surgery, the specific characteristics of both the patient and tumor allow for risk-tailored treatment algorithms including adjuvant radiotherapy and systemic therapy. In this narrative review, we discuss the current radiation treatment paradigm for endometrial cancer with an emphasis on various radiotherapy modalities, techniques, and dosing regimens. We then elaborate on how to tailor radiotherapy treatment courses in combination with other cancer-directed treatments, including chemotherapy and immunotherapy. In conclusion, this review summarizes ongoing research that aims to further individualize radiotherapy regimens for individuals in an attempt to improve patient outcomes.

Cellular therapeutics and immunotherapies in wound healing - on the pulse of time?

Chronic, non-healing wounds represent a significant challenge for healthcare systems worldwide, often requiring significant human and financial resources. Chronic wounds arise from the complex interplay of underlying comorbidities, such as diabetes or vascular diseases, lifestyle factors, and genetic risk profiles which may predispose extremities to local ischemia. Injuries are further exacerbated by bacterial colonization and the formation of biofilms. Infection, consequently, perpetuates a chronic inflammatory microenvironment, preventing the progression and completion of normal wound healing. The current standard of care (SOC) for chronic wounds involves surgical debridement along with localized wound irrigation, which requires inpatient care under general anesthesia. This could be followed by, if necessary, defect coverage via a reconstructive ladder utilizing wound debridement along with skin graft, local, or free flap techniques once the wound conditions are stabilized and adequate blood supply is restored. To promote physiological wound healing, a variety of approaches have been subjected to translational research. Beyond conventional wound healing drugs and devices that currently supplement treatments, cellular and immunotherapies have emerged as promising therapeutics that can behave as tailored therapies with cell- or molecule-specific wound healing properties. However, in contrast to the clinical omnipresence of chronic wound healing disorders, there remains a shortage of studies condensing the current body of evidence on cellular therapies and immunotherapies for chronic wounds. This review provides a comprehensive exploration of current therapies, experimental approaches, and translational studies, offering insights into their efficacy and limitations. Ultimately, we hope this line of research may serve as an evidence-based foundation to guide further experimental and translational approaches and optimize patient care long-term.

Experiences of Motivational Interviewing in Virtual Health-care Visits for Adults With Type 2 Diabetes Mellitus: A Qualitative Analysis.

OBJECTIVES: The purpose of this qualitative study is to identify barriers minimizing the effectiveness of motivational interviewing during virtual clinic encounters for individuals with type 2 diabetes based on the capability, opportunity, motivation, and behaviour (COM-B) model. METHODS: One-on-one semistructured interviews were conducted from March to June 2023, with 17 adults with type 2 diabetes (64.7% female; median age 69 years [range 47 to 83 years]) followed at St. Michael's Hospital (Toronto, Canada). Themes from transcribed interviews were identified through descriptive analysis using a grounded theory approach. RESULTS: The following main themes were identified: 1) face-to-face appointments strengthen provider-patient rapport and collaboration; 2) virtual encounters reduce patient accountability and hinder health-seeking behaviour; and 3) individuals with physical disabilities and/or low technological proficiency experience decreased provider accessibility. Protective factors that can mitigate these negative impacts include establishing rapport during in-person appointments before transitioning to virtual appointments and incorporating a video component during virtual encounters. CONCLUSIONS: Several barriers of virtual appointments currently limit the effectiveness of motivational interviewing for individuals with type 2 diabetes and make it difficult to provide person-centred care, especially by phone. However, there are protective factors that help to maintain healthy lifestyle behaviours, even after transitioning to virtual settings, and are areas for optimization moving forward.

Prolactinoma and Adenomyosis - More than Meets the Eye: A Case Report.

Background/Objective: To report a case of adenomyosis in a woman with hyperprolactinemia which resolved after initiation of dopamine agonist therapy. Case Report: A 35-year-old woman with a history of Graves' disease was referred for evaluation of hyperthyroidism in March 2020. She was started on methimazole and thyroid function normalized. The patient also had a history of a pituitary microadenoma and was previously treated with cabergoline which was stopped after 12 months as she became pregnant.In July 2020, the patient began to have polymenorrhea. Hyperprolactinemia was thought to be an unlikely cause as it most often causes hypogonadotropic hypogonadism with amenorrhea. A pelvic ultrasound demonstrated a bulky uterus with adenomyosis. Gynecology recommended treating adenomyosis by lowering her prolactin levels. She was started on cabergoline 0.25 mg weekly in October 2021. Within 2 months of initiation of cabergoline, she had resolution of symptoms and radiological resolution of adenomyosis. Discussion: Prolactin has been implicated in the pathogenesis of adenomyosis, endometriosis and leiomyomas suggesting that a decrease in prolactin levels may suppress these lesions. The pathogenesis of adenomyosis has been related to direct prolactin effects in the promotion of gland/cell proliferation and function. Conclusion: We conclude that prolonged elevation in prolactin may result in the development of adenomyosis and subsequent prolonged abnormal uterine bleeding. Dopamine agonists, like cabergoline, inhibit the synthesis and secretion of prolactin from the pituitary gland and may have a role in the management of adenomyosis in patients with hyperprolactinemia.

The effects of radiation therapy on the heart: implications for management.

Chemotherapy, radiotherapy, and surgery constitute the three primary modalities employed in the treatment of patients with cancer. Radiotherapy, in particular, is a mainstay of treatment for patients with cancers of the breast, esophagus, lung, and lymph nodes. Prior studies have shown, however, that radiotherapy can impact the heart. Radiation exposure, in fact, can lead to pathophysiological changes that may result in short- and long-term radiation-induced cardiac toxicities. Such toxicities can cause substantial morbidity and may manifest clinically in the weeks to years after the completion of treatment. As a result, in both modern clinical practice and clinical trials, the heart has been recognized as an organ-at-risk, and radiotherapy treatment plans seek to minimize the dose that it receives. In this review, we focus on the impacts of radiotherapy on underlying cardiac risk factors, the pathophysiology of radiotherapy-induced cardiac changes, and the clinical impacts of radiotherapy on the heart. Due to the location of the heart, we focus primarily on patients who have received radiotherapy for cancers of the breast, esophagus, lung, and lymph nodes, and those who have received cardiac-directed therapy. We then elaborate on the ongoing attempts to further lower the doses delivered to the heart during therapeutic courses of radiation.

Trans health training objectives: A scoping review.

BACKGROUND: Transgender individuals are discriminated against in health care environments and consistently experience poorer health outcomes than their cisgender counterparts. Enhancing physician training in transgender-specific health is critical to closing the transgender health gap. METHODS: We conducted a scoping review to identify transgender health training objectives in Internal Medicine and Internal Medicine Subspecialty residency programmes in Canada and the United States. A systematic search was conducted from 1946 to 15 February 2022. Studies were eligible for inclusion if they were written in English, included transgender training objectives, and were aimed at resident physicians in Internal Medicine or Internal Medicine Subspecialty training programmes in Canada or the United States. FINDINGS: We found 4048 papers, of which 11 were included for analysis. Transgender health training objectives were synthesised into five themes, including (1) terminology, physiology, and gender presentation, (2) gender-affirming care and communication, (3) hormonal and surgical management, (4) routine health management and maintenance, and (5) equity, diversity, and inclusion in clinical care. The majority of objectives pertained to equity, diversity, and inclusion in clinical care, namely, respectful communication and non-judgemental care of transgender patients. DISCUSSION: Our findings provide a comprehensive overview of published transgender health objectives in Canada and the United States and highlight existing gaps in postgraduate medical education for Internal Medicine and Subspecialty programmes. CONCLUSIONS: We argue a need for standardisation of transgender-related residency training and suggest that postgraduate Internal Medicine programmes can utilise this review as a framework to begin enhancing transgender health education for their residents.

Immune Escape in Glioblastoma: Mechanisms of Action and Implications for Immune Checkpoint Inhibitors and CAR T-Cell Therapy.

Glioblastoma, the most common primary brain cancer in adults, is characterized by a poor prognosis and resistance to standard treatments. The advent of immunotherapy has revolutionized the treatment of several cancers in recent years but has failed to demonstrate benefit in patients with glioblastoma. Understanding the mechanisms by which glioblastoma exerts tumor-mediated immune suppression in both the tumor microenvironment and the systemic immune landscape is a critical step towards developing effective immunotherapeutic strategies. In this review, we discuss the current understanding of immune escape mechanisms in glioblastoma that compromise the efficacy of immunotherapies, with an emphasis on immune checkpoint inhibitors and chimeric antigen receptor T-cell therapy. In parallel, we review data from preclinical studies that have identified additional therapeutic targets that may enhance overall treatment efficacy in glioblastoma when administered alongside existing immunotherapies.

Assessing the feasibility, acceptability, and fidelity of a tele-retinopathy-based intervention to encourage greater attendance to diabetic retinopathy screening in immigrants living with diabetes from China and African-Caribbean countries in Ottawa, Canada: a protocol.

BACKGROUND: Diabetic retinopathy is a leading cause of preventable blindness in Canada. Clinical guidelines recommend annual diabetic retinopathy screening for people living with diabetes to reduce the risk and progression of vision loss. However, many Canadians with diabetes do not attend screening. Screening rates are even lower in immigrants to Canada including people from China, Africa, and the Caribbean, and these groups are also at higher risk of developing diabetes complications. We aim to assess the feasibility, acceptability, and fidelity of a co-developed, linguistically and culturally tailored tele-retinopathy screening intervention for Mandarin-speaking immigrants from China and French-speaking immigrants from African-Caribbean countries living with diabetes in Ottawa, Canada, and identify how many from each population group attend screening during the pilot period. METHODS: We will work with our health system and patient partners to conduct a 6-month feasibility pilot of a tele-retinopathy screening intervention in a Community Health Centre in Ottawa. We anticipate recruiting 50-150 patients and 5-10 health care providers involved in delivering the intervention for the pilot. Acceptability will be assessed via a Theoretical Framework of Acceptability-informed survey with patients and health care providers. To assess feasibility, we will use a Theoretical Domains Framework-informed interview guide and to assess fidelity, and we will use a survey informed by the National Institutes of Health framework from the perspective of health care providers. We will also collect patient demographics (i.e., age, gender, ethnicity, health insurance status, and immigration information), screening outcomes (i.e., patients with retinopathy identified, patients requiring specialist care), patient costs, and other intervention-related variables such as preferred language. Survey data will be descriptively analyzed and qualitative data will undergo content analysis. DISCUSSION: This feasibility pilot study will capture how many people living with diabetes from each group attend the diabetic retinopathy screening, costs, and implementation processes for the tele-retinopathy screening intervention. The study will indicate the practicability and suitability of the intervention in increasing screening attendance in the target population groups. The study results will inform a patient-randomized trial, provide evidence to conduct an economic evaluation of the intervention, and optimize the community-based intervention.

Characteristics of Cancer Epidemiology Studies That Employ Metabolomics: A Scoping Review.

An increasing number of cancer epidemiology studies use metabolomics assays. This scoping review characterizes trends in the literature in terms of study design, population characteristics, and metabolomics approaches and identifies opportunities for future growth and improvement. We searched PubMed/MEDLINE, Embase, Scopus, and Web of Science: Core Collection databases and included research articles that used metabolomics to primarily study cancer, contained a minimum of 100 cases in each main analysis stratum, used an epidemiologic study design, and were published in English from 1998 to June 2021. A total of 2,048 articles were screened, of which 314 full texts were further assessed resulting in 77 included articles. The most well-studied cancers were colorectal (19.5%), prostate (19.5%), and breast (19.5%). Most studies used a nested case-control design to estimate associations between individual metabolites and cancer risk and a liquid chromatography-tandem mass spectrometry untargeted or semi-targeted approach to measure metabolites in blood. Studies were geographically diverse, including countries in Asia, Europe, and North America; 27.3% of studies reported on participant race, the majority reporting White participants. Most studies (70.2%) included fewer than 300 cancer cases in their main analysis. This scoping review identified key areas for improvement, including needs for standardized race and ethnicity reporting, more diverse study populations, and larger studies.

Assessing the sustainability and scalability of a diabetes eHealth innovation: a mixed-methods study.

BACKGROUND: To date, little is known about the sustainability and scalability of MyDiabetesPlan, an eHealth innovation designed to facilitate shared decision-making within diabetes care. To avoid the possibility of its short-lived implementation and promote wider adoption so as to promote patient-centred diabetes care, it is critical to understand MyDiabetesPlan's sustainability and scalability in order to ensure its long-term impact at a greater scale. We sought to identify the sustainability and scalability potential of MyDiabetesPlan and its limiting factors. METHODS: Using a concurrent triangulation mixed-methods approach, data were collected from 20 individuals involved in the development and implementation of MyDiabetesPlan. The National Health Services Sustainability Model (NHSSM) and the Innovation Scalability Self-administered Questionnaire (ISSaQ) were administered using a 'think-aloud' approach and subsequently, short semi-structured interviews were conducted. Mean aggregate scores and stakeholder-specific scores were generated for the NHSSM and ISSaQ, to quantitatively determine facilitating and limiting factors to sustainability and scalability. Content analysis occurred iteratively with qualitative data, to examine commonalities and differences with the quantitative findings. RESULTS: The top facilitating factor to sustaining MyDiabetesPlan was "Staff involvement and training to sustain the process.", whereas the top limiting factors were: "Adaptability of Improved Process", "Senior Leadership Engagement" and "Infrastructure for Sustainability". The top three facilitating factors for scale-up were "Acceptability", "Development with Theory" and "Consistency with Policy Directives." Conversely, the top three limiting factors were "Financial and Human Resources", "Achievable Adoption" and "Broad Reach". Qualitative findings corroborated the limiting/facilitating factors identified. CONCLUSIONS: Addressing staff involvement throughout the dynamic care contexts, and resource constraints impacting scale-up can enhance the sustainability and scalability of MyDiabetesPlan. As such, future plans will focus on garnering organizational leadership buy-in and support, which may address the resource constraints associated with sustainability and scalability and improve the capacity for adequate staff involvement. eHealth researchers will be able to prioritize these limiting factors from the outset of their tool development to purposefully optimize its sustainability and scalability performance.
