Developing an interprofessional decision support tool for diabetic foot ulcers management in primary care within the family medicine group model: a Delphi study in Canada

BACKGROUND

Primary care professionals encounter difficulties coordinating the continuum of care between primary care providers and second-line specialists and adhere to practice guidelines pertaining to diabetic foot ulcers management. Family medicine groups are providing primary care services aimed to improve access, interdisciplinary care, coordination and quality of health services, and reduce emergency department visits. Most professionals working in family medicine groups are primary care physicians and registered nurses. The aim of this study was to develop and validate an interprofessional decision support tool to guide the management of diabetic foot ulcers for primary care professionals working within the family medicine group model.

METHODS

A one-page decision tool developed by the research team was validated by an expert panel using a three-round Delphi protocol held between December 2019 and August 2021. The tool includes 43 individual actions and a care pathway from initial presentation to secondary prevention. Data collection was realized with both paper and electronic questionnaires, and answers were compiled in an electronic spreadsheet. Data was analyzed with use of descriptive statistics, and consensus for each item was defined as ≥ 80% agreement.

RESULTS

Experts from 12 pre-identified professions of the diabetic foot ulcer interdisciplinary care team were included, 39 participants out of the 59 invited to first round (66.1%), 34 out of 39 for second (87.2%) and 22 out of 34 for third (64.7%) rounds. All items included in the final version of the decision support tool reached consensus and were deemed clear, relevant and feasible. One or more professionals were identified to be responsible for every action to be taken.

CONCLUSIONS

This study provided a comprehensive decision support tool to guide primary care professionals in the management of diabetic foot ulcers. Implementation and evaluation in the clinical setting will need to be undertaken in the future.

The Impact of Advance Care Planning on Healthcare Professionals' Well-being: A Systematic Review

CONTEXT

Advance care planning (ACP) improves care for patients with chronic illnesses and reduces family stress. However, the impact of ACP interventions on healthcare professionals' well-being remains unknown.

OBJECTIVE

To systematically review the literature evaluating the impact of ACP interventions on healthcare professionals' well-being.

METHODS

We followed the Joanna Briggs Institute methodology for systematic reviews and registered the protocol in PROSPERO (CRD42022346354). We included primary studies in all languages that assessed the well-being of healthcare professionals in ACP interventions. We excluded any studies on ACP in psychiatric care and in palliative care that did not address goals of care. Searches were conducted on April 4, 2022, and March 6, 2023 in Embase, CINAHL, Web of Science, and PubMed. We used the Mixed Methods Appraisal Tool for quality analysis. We present results as a narrative synthesis because of their heterogeneity.

RESULTS

We included 21 articles published in English between 1997 and 2021 with 17 published after 2019. All were conducted in high-income countries, and they involved a total of 1278 participants. Three reported an interprofessional intervention and two included patient partners. Studies had significant methodological flaws but most reported that ACP had a possible positive impact on healthcare professionals' well-being.

CONCLUSION

This review is the first to explore the impact of ACP interventions on healthcare professionals' well-being. ACP interventions appear to have a positive impact, but high-quality studies are scarce. Further research is needed, particularly using more rigorous and systematic methods to implement interventions and report results.

Factors influencing the engagement of older adults with neurocognitive disorders in the design of decision aids: A qualitative descriptive study

OBJECTIVE

To identify factors influencing the engagement of older adults with neurocognitive disorders (NCDs) in the design of decision aids (DAs).

METHODS

We conducted a qualitative descriptive study using semi-structured interviews with 23 older adults with NCDs who were accompanied by 27 caregivers. This is a secondary analysis of a published study to identify the features of DAs designed for this population and their caregivers.

RESULTS

Several behaviours and attitudes of caregivers and researchers hindered the older adults' engagement in the DA design process. Specific communication strategies can be employed to support their engagement and overcome the communication challenges inherent to this population, such as memory, attention, hearing, or visual impairments. Adopting the appropriate attitude, taking the time, and providing guidance to the older person can help them focus on the topic, while developing trust between participants is a facilitator to obtain their feedback.

CONCLUSION

Findings from this project could serve to inform the communication and co-design of DAs with older people with NCDs and their caregivers.

PRACTICE IMPLICATIONS

Caregivers and researchers have key roles to play in facilitating communication with older persons with NCDs so they are empowered to help in co-designing DAs.

Competency Framework for Podiatric Medicine Training: A Validation Report Based on an Adapted E-Delphi Across Canada

OBJECTIVES

Competency-based medical education has been introduced into many health professional curricula. Based on CanMEDs, a framework has recently been developed for podiatric medicine education in Canada. This study aimed to validate the framework through a consensus of various podiatric medicine experts across Canada.

METHODS

An adapted Delphi method was used for content validation. Two structured online questionnaires were used to gather expert opinions and agreement on the roles and core competencies described in the framework previously developed. The validation consensus threshold was set at a minimum of 80% agreement. The summary of comments and suggestions was used to reformulate certain items after the research team reached a consensus.

RESULTS

Out of the 51 experts invited from the Canadian Podiatric Medicine Association, 19 completed the first-round questionnaire (mean podiatric experience = 24.5 years; standard deviation 17.6). After the first round, "Podiatric Expert", "Communicator" and "Scholar" roles have been modified. After these modifications, a consensus was obtained at the second round completed by 13 experts. Overall, 95% of the experts agreed that the competency framework was relevant even if some indicators would need to be adapted to suit the requirements of each province and territory.

CONCLUSION

This validated framework supports the excellence and the quality of our podiatric educational program. It also promotes the adoption of a uniform education of podiatrists in Canada and worldwide.

Remaining Question: Does Exercise Improve Healing of Diabetic Foot Ulcers?

Even though it is reasonable to think that exercise is beneficial to diabetic foot ulcer healing, there are currently no exercise recommendations for this population. A systematic review published recently attempted to answer this question. However, because of both the scarce and heterogenous literature on the subject identified by the selected study design and the chosen quality appraisal tool that is too permissive and overestimates the treatment effects, no clinical recommendations can be drawn from this review. We advocate for research on this topic in order to obtain more direct evidence that exercise benefits wound healing, and to close the persistent gap of knowledge regarding the impact of exercise on diabetic foot ulcer wound healing.

Collaboration and Partnership in a 5-Level Engagement Framework for Diabetic Foot Ulcer Management: A Patient-oriented Scoping Review

OBJECTIVE

The management of diabetic foot ulcers (DFUs) is complex, and patient engagement is essential for DFU healing, but it often comes down to the patient's consultation. Therefore, we sought to document patients' engagement in terms of collaboration and partnership for DFUs in 5 levels (direct care, organizational, policy level, research, and education), as well as strategies for patient engagement using an adapted engagement framework.

METHODS

We conducted a scoping review of the literature from inception to April 2022 using the Joanna Briggs Institute method and a patient-oriented approach. We also consulted DFU stakeholders to obtain feedback on the findings. The data were extracted using PROGRESS+ factors for an equity lens. The effects of engagement were described using Bodenheimer's quadruple aims for value-based care.

RESULTS

Of 4,211 potentially eligible records, 15 studies met our eligibility criteria, including 214 patients involved in engagement initiatives. Most studies were recent (9 of 15 since 2020) and involved patient engagement at the direct medical care level (8 of 15). Self-management (7 of 15) was the principal way to clinically engage the patients. None of the studies sought to define the direct influence of patient engagement on health outcomes.

CONCLUSIONS

Very few studies described patients' characteristics. Engaged patients were typically men from high-income countries, in their 50s, with poorly managed type 2 diabetes. We found little rigorous research of patient engagement at all levels for DFUs. There is an urgent need to improve the reporting of research in this area and to engage a diversity of patients.

Engagement of Older Adults Receiving Home Care Services and Their Caregivers in Health Decisions in Partnership With Clinical Teams: Protocol for a Multimethod Study to Prioritize and Culturally Adapt Decision Aids for Home Care

BACKGROUND

Older adults (people aged 65 years and older) face many difficult decisions. Patient decision aids (PtDAs) can help them and their families make informed value-congruent decisions. Some PtDAs have been developed for the home care context, but little is known about scaling them for use with older adults in a different culture.

OBJECTIVE

This study aims to (1) assess the scalability of existing PtDAs for older adults in the home care context; (2) prioritize those that best match the decisional needs of older adults in home care; and (3) culturally adapt the prioritized PtDAs so they can be scaled successfully to the Quebec health care system.

METHODS

This multimethod study includes 3 phases. All phases will be overseen by a steering committee of older adults, caregivers, health professionals, decision makers, community organization representatives, and researchers with the needed expertise. In phase 1, we will use the Innovation Scalability Self-administered Questionnaire, a validated scalability self-assessment tool, to assess the scalability of 33 PtDAs previously identified in a systematic review. Based on their scalability, their quality (based on the International Patient Decision Aids Standards), and the importance of the decision point, we will retain approximately a third of these. In phase 2, we will conduct a 2-round web-based Delphi to prioritize the PtDAs selected in phase 1. Using a snowball recruitment strategy, we aim to recruit 60 Delphi participants in the province of Quebec, including older adults, caregivers, health professionals, decision makers involved in home care services, and PtDA experts. In the first round, we will ask participants to rate the importance of several PtDA decision points according to various criteria such as prevalence and difficulty on a 5-point Likert scale (1=not important to 5=very important). Approximately 6 of the highest-rated PtDAs will be retained for presentation in the second round, and we will select up to 3 PtDAs judged as having the highest priority for cultural adaptation. In phase 3, using the Chenel framework and user-centered design methods, we will update and adapt the PtDAs to the Quebec health care system and integrate these PtDAs into an interprofessional shared decision-making training program for home care teams. The adapted PtDAs will respect the International Patient Decision Aids Standards criteria.

RESULTS

This study was funded in March 2022 by the Canadian Institutes of Health Research. Data collection for the web-based Delphi began in October 2023. Results are expected to be published in May 2024.

CONCLUSIONS

This project will provide relevant and culturally appropriate decision support tools for older adults making difficult decisions and their home care teams that will be ready for scaling across the province of Quebec.

The Longevity Protein Klotho: A Promising Tool to Monitor Lifestyle Improvements

Aging is not a disease; it is a natural evolution of human physiology. Medical advances have extended our life expectancy, but chronic diseases and geriatric syndrome continue to affect the increasingly aging population. Yet modern medicine perpetuates an approach based on treatment rather than prevention and education. In order to help solve this ever-growing problem, a new discipline has emerged: lifestyle medicine. Nutrition, physical activity, stress management, restorative sleep, social connection, and avoidance of risky substances are the pillars on which lifestyle medicine is founded. The aim of this discipline is to increase healthspan and reduce the duration of morbidity by making changes to our lifestyle. In this review, we propose the use of klotho protein as a novel biomarker for lifestyle medicine in order to quantify and monitor the health status of individuals, as no integrative tool currently exists.

Do Exercise Programs Improve Fitness, Mobility, and Functional Capacity in Adults With Lower Limb Amputation? A Systematic Review on the Type and Minimal Dose Needed

OBJECTIVE

To answer the following questions: (1) Do physical activity (PA) and exercise improve fitness, mobility, and functional capacity among adults with lower limb amputation (LLA) and (2) What is the type and minimum dose of PA (frequency, intensity and duration) needed?

DESIGN

Systematic review.

SETTING

Outpatient intervention, outside of the prosthetic rehabilitation phase.

PARTICIPANTS

Adults with lower limb amputation living in the community.

INTERVENTION

Any physical activity or exercise intervention.

OUTCOMES AND MEASURES

Any fitness, mobility, or functional capacity indicators and measurements.

RESULTS

Twenty-three studies were included, totaling 408 adults with LLA. Studies evaluated the effect of structured PA sessions on fitness, mobility, and functional capacity. The highest evidence is for mixed exercise programs, that is, programs combining aerobic exercise with strengthening or balance exercise. There is moderate confidence that 1-3 sessions of 20-60 minutes of exercise per week improves balance, walking speed, walking endurance, and transfer ability in adults with LLA above the ankle. As for flexibility, cardiorespiratory health, lower-limb muscles strength, and functional capacity, there was low confidence that exercise improves these fitness components because of the lack of studies.

CONCLUSION

Exercise 1-3 times per week may improve balance, walking speed, walking endurance, and transfer ability in adults with LLA, especially when combining aerobic exercises with lower limb strengthening or balance exercises. There is a need for most robust studies focusing on the effect of PA on cardiorespiratory health, muscles strength, flexibility, and functional status.

Reporting of Rehabilitation Outcomes in the Traumatic Lower Limb Amputation Literature: A Systematic Review

OBJECTIVE

To synthesize the outcomes reported in the rehabilitation and community literature for adults with traumatic lower limb amputation (LLA).

DATA SOURCES

The search strategy was conducted in 3 databases (Medline, EMBASE, and CINAHL) from inception to April 2022.

STUDY SELECTION

To be eligible, articles could be of any design but were required to have at least 50% adult individuals with traumatic LLA and had to report on interventions and outcomes in either a rehabilitation or community setting.

DATA EXTRACTION

The extracted outcomes were classified using Dodd's framework, which is designed for organizing research outcomes. Heterogeneity was observed in the outcome measures (OMs) used for evaluation. Two reviewers independently conducted the data extraction, which was verified by a third reviewer.

DATA SYNTHESIS

Of the 7,834 articles screened, 47 articles reporting data on 692 individuals with traumatic LLA, met our inclusion criteria. Four core areas encompassing 355 OMs/indicators were identified: life effect (63.4%), physiological/clinical (30.1%), resource use (5.1%), and adverse events (1.4%). Physical functioning (eg, gait, mobility) was the most frequently reported outcome domain across studies, followed by nervous system outcomes (eg, pain) and psychiatric outcomes (eg, depression, anxiety). Domains such as global quality of life and role/emotional functioning were seldomly reported.

CONCLUSION

The study provides a list of outcome indicators explicitly published for adults with traumatic LLA, highlighting inconsistent reporting of outcome indicators. The lack of a standardized set of OMs is a barrier to performing meta-analyses on interventions, preventing the identification of effective care models and clinical pathways. Developing a core outcome set that includes OMs relevant to the needs of the traumatic LLA population may address these issues.

Diabetic foot complications among Indigenous peoples in Canada: a scoping review through the PROGRESS-PLUS equity lens

Introduction

Indigenous peoples in Canada face a disproportionate burden of diabetes-related foot complications (DRFC), such as foot ulcers, lower extremity amputations (LEA), and peripheral arterial disease. This scoping review aimed to provide a comprehensive understanding of DRFC among First Nations, Métis, and Inuit peoples in Canada, incorporating an equity lens.

Methods

A scoping review was conducted based on Arksey and O'Malley refined by the Joanna Briggs Institute. The PROGRESS-Plus framework was utilized to extract data and incorporate an equity lens. A critical appraisal was performed, and Indigenous stakeholders were consulted for feedback. We identified the incorporation of patient-oriented/centered research (POR).

Results

Of 5,323 records identified, 40 studies were included in the review. The majority of studies focused on First Nations (92%), while representation of the Inuit population was very limited populations (< 3% of studies). LEA was the most studied outcome (76%). Age, gender, ethnicity, and place of residence were the most commonly included variables. Patient-oriented/centered research was mainly included in recent studies (16%). The overall quality of the studies was average. Data synthesis showed a high burden of DRFC among Indigenous populations compared to non-Indigenous populations. Indigenous identity and rural/remote communities were associated with the worse outcomes, particularly major LEA.

Discussion

This study provides a comprehensive understanding of DRFC in Indigenous peoples in Canada of published studies in database. It not only incorporates an equity lens and patient-oriented/centered research but also demonstrates that we need to change our approach. More data is needed to fully understand the burden of DRFC among Indigenous peoples, particularly in the Northern region in Canada where no data are previously available. Western research methods are insufficient to understand the unique situation of Indigenous peoples and it is essential to promote culturally safe and quality healthcare.

Conclusion

Efforts have been made to manage DRFC, but continued attention and support are necessary to address this population's needs and ensure equitable prevention, access and care that embraces their ways of knowing, being and acting.

Prescribing Home Digital Thermometry Coupled with Activity Dosing and Optimized Offloading to Prolong Diabetic Foot Remission: A Case Report

People with a history of diabetic foot ulcers (DFUs) experience diminished health-related quality of life and are at a 40% annual risk of DFU recurrence. Due to a fear of DFU recurrence, people in DFU remission participate less in physical activity and moderate-intensity exercise when compared to people with diabetes who have not had wounds. There is novel evidence to suggest that too little activity during DFU remission contributes to only low magnitudes of repetitive tissue loading creating a higher susceptibility to skin trauma during inadvertent high-activity bouts. Conversely, a hasty return to too much activity could lead to rapid recurrence. There is now high-level evidence from multiple meta-analyses to indicate that home-based foot temperature monitoring, coupled with activity modification and daily inspection of the feet for impending signs of ulceration, could reduce the risk of ulcer recurrence by 50%. There is little evidence, however, to guide the decision-making regarding the appropriate quantity and frequency of physical activity during DFU remission and the acceptability from the patient perspective. This has resulted in limited uptake of this novel intervention in clinical practice. Earlier, we proposed that activity can be dosed for people in foot ulcer remission, just like insulin or medication is dosed. Here, we describe a patient-centered approach to implementing home foot temperature monitoring coupled with daily foot checks and dosage-based return to physical activity in a patient in DFU remission, including his perspective. We believe using such an approach could maximize ulcer-free days in remission, thereby improving quality of life.

Using a contralateral shoe lift to reduce gait deterioration during an offloading fast-walk setting in diabetic peripheral neuropathy: A comparative feasibility study

AIMS

Diabetic peripheral neuropathy (DPN) is a predictor of foot ulcers and leads to sedentary behaviour. This comparative study evaluated gait and feasibility of a 20-minute fast walk, at 40-60% of cardiopulmonary capacity, in individuals with DPN wearing an offloading boot and a contralateral shoe balancer.

METHODS

Gait parameters were measured with inertial sensors on 32 individuals (group with DPN [n = 16], group with diabetes but without DPN [n = 9], and a group without diabetes/DPN [n = 7]). Feasibility was assessed by feedback on perceived effort and adverse events. Gait outcomes were compared between groups with or without a shoe balancer using one-way ANOVAs.

RESULTS

The three groups were equivalent in terms of activity level and age and gender except for the body mass index. Both groups with diabetes exhibited minimal decreased gait speed (p > 0.005) and the DPN group exhibited increased double-support percentage (+4.6%, p = 0.01) while walking with an offloading boot and contralateral shoe balancer. The use of a contralateral shoe balancer reduced gait asymmetry. Lower physical activity level was associated with further gait deterioration in all groups. Few adverse events were reported, and 91% of participants reported that the proposed activity would be feasible daily.

CONCLUSIONS

The offloading boot deteriorated gait function, but a contralateral shoe balancer minimized its impact, especially in the context of physical activity in people with diabetes and DPN.

Upstream comprehensive management of individuals with diabetes with multimorbidity and frailty to act against amputation

This manuscript constitutes a commentary on: "Retrospective cohort study of long-term outcomes and prognostic factors for survival after lower extremity amputation in patients with diabetes" by Vuorlaakso et al. (2023). We aim to contribute to the reflection of their findings to support the comprehensive management of vulnerable individuals with multimorbidity and/frailty for limb preservation. There is an urgent need to understand the effects of frailty on overall survival after amputation, survival without major amputation, and the effect modification with multimorbidity.

Frailty in People with Chronic Limb Threatening Ischemia and Diabetes-Related Foot Ulcers: A Systematic Review

BACKGROUND

Frailty represents a state of multisystem impairment that may adversely impact people presenting with chronic limb-threatening ischemia (CLTI) and diabetes-related foot ulcers (DFUs). The aim of this systematic review was to explore the association between frailty and outcomes from CLTI and DFUs.

METHODS

We performed a systematic literature search of electronic databases to find studies using a validated measure of frailty in individuals with CLTI and/or DFUs. The primary outcomes were the impact of frailty on the severity of initial clinical presentation and unfavorable follow-up outcomes including readmissions, major limb amputation, cardiovascular events, revascularization, and wound healing.

RESULTS

Ten cohort studies were included. Two studies had a low risk of bias, 1 was unable to be assessed, 5 had moderate risk of bias, and 2 high risk of bias. The prevalence of frailty in people presenting with CLTI ranged from 27% to 88% and was 71% in people with DFUs. The presence of frailty in both people with CLTI and DFUs was associated with substantially increased severity at presentation (severity of ischemia and tissue loss) and poorer outcomes at follow-up (risk of readmission, limb amputation, and all-cause mortality).

CONCLUSIONS

The presence of frailty in both people with CLTI and DFUs is likely associated with substantially higher complexity at presentation followed by a greater risk for readmission, amputation, and death during follow-up. Heterogeneity in the tools used to screen for frailty, poor definition of frailty, and unclear evaluation of exposure and outcomes limit further interpretation of findings.

Provision of Compassionate and Empathic Care as a Well-Being Preservation Tool for Emergency Physicians: A Scoping Review

Objective

Compassion and physician well-being are two key components related to quality care in health including emergency medicine. The objective of this study was to explore the impact of compassion in care on the well-being of emergency physicians. We conducted a scoping review to explore the impact of provision of compassionate care by emergency physicians on their well-being and subconcepts.

Methods

Four electronic databases and grey literature were searched to find evidence related to compassion, empathy, self-compassion, and their impact on emergency physicians' well-being. Following title and abstract review, two reviewers independently screened full-text articles, and extracted data. Data were presented using descriptive statistics and a narrative analysis.

Results

A total of 803 reports were identified in databases. Three articles met eligibility criteria for data extraction. None directly examined compassion and well-being. Included studies addressed empathy and burnout in emergency medicine professionals.

Conclusion

No high-quality evidence could be found on the topic in the population of interest. Literature related to the topic of compassion in physicians, especially in emergency physicians, a field known for its high demand and stress levels, is currently scarce and additional evidence is needed to better describe and understand the association between physicians' compassion and well-being.

Effectiveness of Shared Decision-making Training Programs for Health Care Professionals Using Reflexivity Strategies: Secondary Analysis of a Systematic Review

BACKGROUND

Shared decision-making (SDM) leads to better health care processes through collaboration between health care professionals and patients. Training is recognized as a promising intervention to foster SDM by health care professionals. However, the most effective training type is still unclear. Reflexivity is an exercise that leads health care professionals to question their own values to better consider patient values and support patients while least influencing their decisions. Training that uses reflexivity strategies could motivate them to engage in SDM and be more open to diversity.

OBJECTIVE

In this secondary analysis of a 2018 Cochrane review of interventions for improving SDM by health care professionals, we aimed to identify SDM training programs that included reflexivity strategies and were assessed as effective. In addition, we aimed to explore whether further factors can be associated with or enhance their effectiveness.

METHODS

From the Cochrane review, we first extracted training programs targeting health care professionals. Second, we developed a grid to help identify training programs that used reflexivity strategies. Third, those identified were further categorized according to the type of strategy used. At each step, we identified the proportion of programs that were classified as effective by the Cochrane review (2018) so that we could compare their effectiveness. In addition, we wanted to see whether effectiveness was similar between programs using peer-to-peer group learning and those with an interprofessional orientation. Finally, the Cochrane review selected programs that were evaluated using patient-reported or observer-reported outcome measurements. We examined which of these measurements was most often used in effective training programs.

RESULTS

Of the 31 training programs extracted, 24 (77%) were interactive, among which 10 (42%) were considered effective. Of these 31 programs, 7 (23%) were unidirectional, among which 1 (14%) was considered effective. Of the 24 interactive programs, 7 (29%) included reflexivity strategies. Of the 7 training programs with reflexivity strategies, 5 (71%) used a peer-to-peer group learning strategy, among which 3 (60%) were effective; the other 2 (29%) used a self-appraisal individual learning strategy, neither of which was effective. Of the 31 training programs extracted, 5 (16%) programs had an interprofessional orientation, among which 3 (60%) were effective; the remaining 26 (84%) of the 31 programs were without interprofessional orientation, among which 8 (31%) were effective. Finally, 12 (39%) of 31 programs used observer-based measurements, among which more than half (7/12, 58%) were effective.

CONCLUSIONS

Our study is the first to evaluate the effectiveness of SDM training programs that include reflexivity strategies. Its conclusions open avenues for enriching future SDM training programs with reflexivity strategies. The grid developed to identify training programs that used reflexivity strategies, when further tested and validated, can guide future assessments of reflexivity components in SDM training.

Competency Framework for Podiatric Medicine Training in Canada: An Adapted Delphi Study

PURPOSE

Podiatrists are generally defined as professionals with high-level skills in the prevention and management of local foot conditions that are not systemic diseases. Across countries, different academic trainings are implemented due to the specific context and practice of podiatric medicine. It is thus essential to support country-specific podiatry education for the development of highly skilled podiatrists. Therefore, we report the development of a podiatric medicine competency framework to support training in Canada.

PARTICIPANTS AND METHODS

A Delphi process was conducted by 12 stakeholders (including 8 podiatry experts) from the University of Québec at Trois-Rivières which is the only university offering the degree of Doctor of Podiatric Medicine (DPM) in Canada. The developed framework is (1) based on the seven key roles of the Canadian medical education directives of specialists (CanMEDs) and, (2) closely aligned with the requirement of the College of Podiatrists of Québec which sets the standards of entry to practice in Québec.

RESULTS

The developed framework represents the state of the development process and the consensus of the podiatry experts. It reflects the expected profile of the institution's DPM graduates based on seven key roles (podiatry expert, communicator, collaborator, health advocate, leader and manager, scholar, and professional). This developed framework is an arborescence of complex skills defined in tangible indicators that characterize each expected part of a core competency. Twenty-four core competencies have been determined and divided into 84 enabling competencies and 288 observable indicators.

CONCLUSION

This competency framework has been designed to support high-quality education and to develop podiatry. Next steps include: (1) validation of this framework by external experts, (2) development of rigorous evaluation methods and, (3) concrete actions for its implementation and assessment. This framework would help to define the scope of practice and capabilities of podiatric medicine, both in Canada and internationally.

Outcomes of Hallux Amputation Versus Partial First Ray Resection in People with Non-Healing Diabetic Foot Ulcers: A Pragmatic Observational Cohort Study

There are few data comparing outcomes after hallux amputation or partial first ray resection after diabetic foot ulcer (DFU). In a similar context, the choice to perform one of these two surgeries is attributable to clinician preference based on experience and characteristics of the patient and the DFU. Therefore, the purpose of this study was to determine the more definitive surgery between hallux amputation and partial first ray resection. We abstracted data from a cohort of 70 patients followed for a 1-year postoperative period to support clinical practice. We also attempted to identify patient characteristics leading to these outcomes. Our results suggested no statistical difference between the type of surgery and outcomes such as recurrence of DFU and amputation at 3, 6, and 12 months or death. However, there was a statistically significantly increased likelihood of re-ulceration for patients with CAD who underwent hallux amputation (p = 0.02). There was also a significantly increased likelihood of re-ulceration for people with depression or a history when the partial ray resection was performed (p = 0.02). Patients with prior amputation showed a higher probability of undergoing another re-amputation with partial ray resection (p = 0.01). Although the trends that emerge from this project are limited to what is observed in this statistical context, where the number of patients included and the number of total observations per outcome were limited, it highlights interesting data for future research to inform clinical decisions to support best practices for the benefit of patients.

Evolution of WIfI: Expansion of WIfI Notation After Intervention

Nearly a decade ago, the Society for Vascular Surgery (SVS)'s wound, ischemia, and foot Infection (WIfI) classification was first developed to help assess overall limb threat. However, managing conditions such as diabetic foot ulcer and chronic limb-threatening ischemia can be complex. For instance, certain investigative findings might initially be pending such as the level of ischemia or extent of infection before the final classification is established. In addition, wounds evolve rapidly, and the current classification does not allow for tracking their progression over time during treatment. Therefore, we propose a supplemental consistent notation for scoring WifI re-assessment during treatment of a threatened limb inspired by the cancer staging before and after neoadjuvant treatment classification system. Thus, we describe the re-scoring system and how to use it. Our suggestion supports a coherent method to longitudinally communicate characteristics of a threatened limb. This has potential to support high quality interdisciplinary, patient-centered care and enhance the use of this classification in research. Further work is required to validate this modification of a common language of risk.

Effects of foot orthoses on the biomechanics of the lower extremities in adults with and without musculoskeletal disorders during functional tasks: A systematic review

BACKGROUND

Foot orthoses are among the most commonly used external supports to treat musculoskeletal disorders. It remains unclear how they change the biomechanics of the lower extremities during functional tasks. This systematic review aimed to determine the effects of foot orthoses on primary outcomes (i.e., kinematics, kinetics and electromyography of the lower extremities) in adults with and without musculoskeletal disorders during functional tasks.

METHODS

A literature search was conducted for articles published from inception to June 2021 in Medline, CINAHL, SPORTDiscus, Cochrane libraries and PEDro electronic databases. Two investigators independently assessed the titles and abstracts of retrieved articles based on the inclusion criteria. Of the 5578 citations, 24 studies were included in the qualitative synthesis as they reported the effects of foot orthoses on the primary outcomes. Risk of bias of included studies was determined using the modified Downs and Black Quality Index.

FINDINGS

During low impact tasks, foot orthoses decrease ankle inversion and increase midfoot plantar forces and pressure. During higher impact tasks, foot orthoses had little effects on electromyography and kinematics of the lower extremities but decreased ankle inversion moments.

INTERPRETATION

Even though the effects of foot orthoses on the biomechanics of the lower extremities seem task-dependent, foot orthoses mainly affected the biomechanics of the distal segments during most tasks. However, few studies determined their effects on the biomechanics of the foot. It remains unclear to what extent foot orthoses features induce different biomechanical effects and if foot orthoses effects change for different populations.

Discussing around a virtual fire: Citizen engagement in a shared Decision-Making conference

An online conference was organized to promote the Interprofessional Shared Decision-Making model and maximize its dissemination among stakeholders (citizens, health care providers, administrative staffs, policy makers, academics) in Canada. The goal was to enhance knowledge of and engagement in shared decision-making in a patient-oriented research, since shared decision-making has been hampered by reduced face-to-face contact, fear of infection, and overworked health professionals due to the COVID-19 pandemic. Therefore, we share a summary of what has been done to engage citizens in shared decision-making and to inform the interprofessional community about active citizen engagement in an online conference.

Effectiveness of saline water and lidocaine injection treatment of intractable plantar keratoma: a randomised feasibility study

Background

An intractable plantar keratoma (IPK) is a conical thickening of the epidermis’ stratum corneum and a common cause of foot pain which can have a significant, detrimental impact on the mobility, quality of life and independence of individuals. Conservative treatments are currently offered to patients with IPK, but they are unsatisfactory since they do not offer a sufficient or permanent reduction of symptoms. The purpose of this study was the evaluation of the feasibility, safety and effectiveness of innovative treatments for intractable plantar keratoma (IPK).

Methods

A randomized single blind trial with 40 patients divided with block randomization in four parallel groups was conducted to compare treatment combinations: conservative sharp debridement only or sharp debridement with needle insertion, physiological water injection or lidocaine injection. All patients obtained the same treatment four times at a four-week interval. At each visit, visual analog scale (VAS), Foot Function Index (FFI) and IPK size were evaluated. VAS and FFI were also completed at a six and twelve-month follow-up.

Results

Our findings in regards to feasibility demonstrated recruitment challenges because of the anticipated pain that would be provoked by needle insertion may not be worth the potential pain relief compared to debridement alone from the patient’s perspective. This was also the principal cause of drop out. Our preliminary results show no main effect of group for any of the clinical outcomes: pain felt on VAS, FFI score, IPK’s size (p > 0.05). However, the analysis revealed a statistically significant effect of time on VAS (p < 0.001), FFI score (p < 0.001) and IPK’s size (width and depth (p < 0.001); length (p = 0.001)), but no group x time interaction was found (p > 0.05).

Conclusions

This study demonstrates that IPK treatment consisting of sharp debridement with needle insertion, physiological saline water injection or lidocaine injection is feasible and safe. There was a non-statistically significant trend toward diminishing pain intensity compared to scalpel debridement alone. The pain provoked by needle insertion and injection treatments must be addressed with a scientifically proven protocol to make it more comfortable for patients before these treatments could be considered in further studies.

Adequacy Between Canadian Clinical Guidelines and Recommendations Compared With International Guidelines for the Management of Diabetic Foot Ulcers

OBJECTIVES

Although quality of care in the prevention and management of diabetic foot ulceration (DFU) has improved with the use of comprehensive evidence-based clinical practice guidelines, disparities between national and international guidelines have been demonstrated in one study conducted in Western Pacific regions. Although there are challenges of systematic implementation of evidence-based care in some clinical settings, their applications have demonstrated positive outcomes on DFU-associated burdens in many countries. The aim of this study was to review and evaluate 3 Canadian clinical practice guidelines and recommendations (CPGRs) in comparison with the 2019 International Working Group on the Diabetic Foot (IWGDF) guidelines.

METHODS

Extraction of all 85 recommendations from the IWGDF guidelines was performed and 3 independent investigators used a rating recommendations adequacy method with descriptive statistics. The Appraisal of Guidelines REsearch & Evaluation (AGREE) II instrument was used for quality appraisal and reliability scores were noted using intraclass correlation coefficients.

RESULTS

The Wounds Canada CPGR had the higher adequacy with the IWGDF guidelines. However, its development method was poor to fair. The Registered Nurses' Association of Ontario CPGR was superior for its development and implementation strategies, but major gaps were found in all chapters. The Diabetes Canada CPGR obtained a good quality appraisal evaluation, but was not dedicated exclusively to DFU and some important recommendations were absent. Reliability scores of AGREE II were good between investigators (p<0.0001). Some disparities were noted between Canadian and international recommendations.

CONCLUSIONS

Some disparities were noted, future orientations for development should include various health-care professionals involved in the team approach, patient-oriented research, recommendations published along with their level of evidence and strength of recommendations (such as with the Grading of Recommendations, Assessment, Development and Evaluations system) and implementation strategies to enhance evidence-based practice in Canada.

[Multidisciplinary management of diabetic foot ulcer infection]

Infection is one of the most common complications of diabetic foot ulceration resulting in lower extremity amputations and early mortality in this population. Several factors influence the course of diabetic foot ulceration infection and in that context, integrated multidisciplinary management is required as soon as possible. In fact, a holistic interdisciplinary approach should be the standard of care. Whether the infection is categorized as mild, moderate or severe, with or without bone infection, the overall individual's characteristics must be addressed, in addition to local wound care, offloading and antibiotic therapy. Some severe infections have potential indications for hospitalization and are considered as surgical emergencies. In some DFU cases, surgical revascularization of the limb is mandatory to treat the infection. However, surgical interventions and amputations, are sometimes inevitable, they are predictors of bad prognosis. Although some adjuvant therapies are effective to promote wound healing, their use is not recommended to treat diabetic foot ulcer infection. Infection management can be divided into three general interventions: proper clinical diagnosis, microbiological and imaging investigations, and treatment. This review is an update on the up-to-date evidences in scientific literature and includes the latest recommendations from the International Working Group on the Diabetic Foot (IWGDF).

Multidisciplinary Management of Diabetic Foot Ulcers in Primary Cares in Quebec: Can We Do Better?

A growing body of evidence supports the presence of integrated foot care based on multidisciplinary and interdisciplinary teams in the management and prevention of diabetic foot ulcer (DFU) worldwide. This model of care is however rare in the clinical setting in Quebec, Canada. Many best practice gaps are identified as well as probable causal hypothesis are listed in this commentary. We support our opinions with a pilot audit conducted as part of a continuous quality improvement process in managing patients with DFU in our area and on Canadian facts and data. Our pilot study (n = 27 hospitalized patients) included a typical DFU population with neuropathy, peripheral arterial disease and previous amputation. It highlights underachievement of best practice recommendations implementation such as multidisciplinary DFU management and offloading interventions in our establishment. Due the high morbidity and mortality associated with DFU patients, four died during the studied hospitalization episode. Several barriers were encountered in the pilot audit justifying that no robust conclusion can be raised. However, our observations are concerning. Even though data accessibility was limited, our observations are sadly coherent with what is found in the literature. Economic data of what this means for our health system is put forward in the overall discussion. We are preoccupied by the trends outlined by some facts and observations, and this commentary was written with this in mind. In the face of the diabetes crisis that is arising, a plea is made to reassess care pathway for this vulnerable population as we emphasize the importance of teamwork in managing DFU.

New Antibacterial Paper Made of Silver Phosphate Cellulose Fibers: A Preliminary Study on the Elimination of Staphylococcus aureus Involved in Diabetic Foot Ulceration

AIM

To evaluate in vitro the antibacterial effect of a paper made of silver phosphate cellulose fibers (SPCF) on Staphylococcus aureus, the most common diabetic foot ulceration (DFU) pathogen when compared with other common commercial products.

METHODS

The antibacterial activity of SPCF samples was evaluated through time with cell counting on agar plates. SPCF samples were then compared with commercial wound care products currently in use in DFU treatments (Silvercel™, Acticoat 7, and Aquacel Ag ExtraTM) through time on agar plates (growth inhibition zones).

RESULTS

After 6 hours, there was no viable bacterial cell detected on either plate (p < 0.05). There was a net growth inhibition zone for SPCF samples but no significant difference between the two silver concentrations. Compared with common commercial products, SPCF paper provides results equal to Acticoat 7 (p < 0.05). There was a net growth inhibition zone for SPCF samples but no significant difference between the two silver concentrations. Compared with common commercial products, SPCF paper provides results equal to Acticoat 7 (p < 0.05). There was a net growth inhibition zone for SPCF samples but no significant difference between the two silver concentrations. Compared with common commercial products, SPCF paper provides results equal to Acticoat 7 (.

CONCLUSIONS

These results have shown the efficiency of SPCF paper to eliminate Staphylococcus aureus in these conditions. SPCF papers are effective when compared with other common commercial products and could have an industrial potential in wound care. Infected DFU could benefit from the antibacterial effectiveness of SPCF, but more relevant experimentations related to foot ulcers are needed.Staphylococcus aureus, the most common diabetic foot ulceration (DFU) pathogen when compared with other common commercial products.

Establishing a multidisciplinary partnership integrating podiatric care into the Quebec public health-care system to improve diabetic foot outcomes: A retrospective cohort

Diabetic foot ulcers (DFUs) are one of the main complications of diabetes affecting many Canadians that need to be effectively managed. There is limited data concerning outcomes of Canadian patients with DFUs treated with a team approach in the public health system. Podiatrists are known to be key members of a multidisciplinary team approach to DFUs management, but in Quebec, Canada, they are only available in private practice. The aim of this study is to evaluate diabetic foot outcomes after integrating podiatric care into in-hospital wound care clinic settings. A 12-month retrospective cohort study was conducted into a new organization named the Pododiabetology University Center (PUC), which is described in this article. Healing rate and healing time were the outcomes measured. The analysis was performed by comparing data collected before and after the integration of the podiatrists. Preliminary results indicate that 73.2% of DFUs (n=52) healed in an average of 19.8 weeks (time to wound closure). Previous data collected on 15 individuals before the integration of podiatric care showed a 27.3% of DFUs resolved in 44.6 weeks. The findings suggest that a patient with DFUs who receives wound care from a multidisciplinary team that includes a podiatrist can improve both their healing rate and time. An integrated multidisciplinary approach including podiatrists for patients affected by acute DFU is highly suggested in the literature in order to reduce the number of hospitalizations, amputations and financial burden, which are variables that could be evaluated in further studies.

Baseline characteristics and outcomes of children with cancer in the English-speaking Caribbean: A multinational retrospective cohort

BACKGROUND

English-speaking Caribbean (ESC) childhood cancer outcomes are unknown.

PROCEDURE

Through the SickKids-Caribbean Initiative (SCI), we established a multicenter childhood cancer database across seven centers in six ESC countries. Data managers entered patient demographics, disease, treatment, and outcome data. Data collection commenced in 2013, with retrospective collection to 2011 and subsequent prospective collection.

RESULTS

A total of 367 children were diagnosed between 2011 and 2015 with a median age of 5.7 years (interquartile range 2.9-10.6 years). One hundred thirty (35.4%) patients were diagnosed with leukemia, 30 (8.2%) with lymphoma, and 149 (40.6%) with solid tumors. A relative paucity of children with brain tumors was seen (N = 58, 15.8%). Two-year event-free survival (EFS) for the cohort was 48.5% ± 3.2%; 2-year overall survival (OS) was 55.1% ± 3.1%. Children with acute lymphoblastic leukemia (ALL) and Wilms tumor (WT) experienced better 2-year EFS (62.1% ± 6.4% and 66.7% ± 10.1%), while dismal outcomes were seen in children with acute myeloid leukemia (AML; 22.7 ± 9.6%), rhabdomyosarcoma (21.0% ± 17.0%), and medulloblastoma (21.4% ± 17.8%). Of 108 deaths with known cause, 58 (53.7%) were attributed to disease and 50 (46.3%) to treatment complications. Death within 60 days of diagnosis was relatively common in acute leukemia [13/98 (13.3%) ALL, 8/26 (30.8%) AML]. Despite this, traditional prognosticators adversely impacted outcome in ALL, including higher age, higher white blood cell count, and T-cell lineage.

CONCLUSIONS

ESC childhood cancer outcomes are significantly inferior to high-income country outcomes. Based on these data, interventions for improving supportive care and modifying treatment protocols are under way. Continued data collection will allow evaluation of interventions and ensure maximal outcome improvements.

Pharmacokinetic modelling and validation of the half-life extension needed to reduce the burden of infusions compared with standard factor VIII

INTRODUCTION

Currently, no universally accepted definition of extended half-life (EHL) recombinant FVIII (rFVIII) exists. Identifying the minimum half-life extension ratio required for a reduction in dosing frequency compared with standard rFVIII could enable a more practical approach to decisions around prophylaxis with EHL rFVIII.

AIM

To identify the half-life extension ratio required to decrease rFVIII dosing frequency by at least 1 day while maintaining the proportion of patients with plasma rFVIII levels above 1 IU/dL and without increasing the total weekly dose.

METHODS

A previously published population pharmacokinetic model for standard rFVIII was used to estimate the percentage of patients with factor VIII (FVIII) levels always >1 IU/dL using various benchmark regimens. Using modelling, dosing frequency was reduced while rFVIII half-life was extended until the percentage of patients with FVIII >1 IU/dL equalled that of the benchmark regimen.

RESULTS

Benchmark 3×/wk dosing totalling 100 IU/kg/wk of rFVIII resulted in 56.6% of patients with FVIII levels always >1 IU/dL. With 2×/wk dosing, totalling 80 or 90 IU/kg/wk, half-life extensions required to maintain 56.6% of patients at FVIII levels >1 IU/dL were 1.30 and 1.26, respectively. A half-life extension ratio of 1.33 was required to change dosing from every 48 hours to every 72 hours (both at 105 IU/kg/wk) while maintaining 92.8% of patients with FVIII >1 IU/dL.

CONCLUSION

Based on this investigation, EHL rFVIII products should have a minimum half-life extension ratio of 1.3 to provide a reduction in dosing frequency from 3× to 2×/wk compared with standard rFVIII products while maintaining the same minimum FVIII trough level.

Enzymatic debridement with collagenase in wounds and ulcers: a systematic review and meta-analysis

Enzymatic debridement with collagenase is a technique that is commonly used in clinical practice. This systematic review examines the effect of collagenase on all kinds of wounds, compared to an alternative therapy, on wound healing, wound bed characteristics, cost-effectiveness and the occurrence of adverse events. We conducted a systematic literature search on available literature in Cochrane databases, MEDLINE, EMBASE and CINAHL. Two investigators independently assessed the titles and abstracts of all randomised controlled trials obtained involving collagenase of all kinds of wounds based on inclusion criteria. Of the 1411 citations retrieved, 22 studies reported outcomes with the use of collagenase either for wound healing or wound debridement. Results support the use of collagenase for enzymatic debridement in pressure ulcers, diabetic foot ulcers and in conjunction with topical antibiotics for burns. However, studies presented a high risk of bias. Risk ratio of developing an adverse event related to collagenase versus the alternative treatment was statistically significant (for 10 studies, RR: 1·79, 95% CI 1·24-2·59, I² =0%, P = 0·002). There is very limited data on the effect of collagenase as an enzymatic debridement technique on wounds. More independant research and adequate reporting of adverse events are warranted.

Comparing the burden of illness of haemophilia between resource-constrained and unconstrained countries: the São Paulo-Toronto Hemophilia Study

INTRODUCTION

Although the regular replacement of clotting factor concentrates (prophylaxis) has been well established as the standard of care for severe haemophilia, the high cost of factor concentrates has limited access to prophylaxis in countries with under-developed or developing economies.

AIMS

We studied the health gap that could be addressed by providing unlimited access to clotting factor concentrates with implementation of long-term prophylaxis initiated from an early age in life.

METHODS

We performed a cross-sectional study of a random, representative sample of boys with moderate and severe haemophilia at three haemophilia treatment centres in Sao Paulo, Brazil, and one centre in Toronto, Canada.

RESULTS

Canadian subjects were more often treated with prophylaxis, and began treatment at an earlier age. Fewer Canadian subjects had bleeds within the preceding 6 months (19 vs. 34, P = 0.003). Canadian subjects had lower (better) Pettersson radiographic scores (1.5 vs. 6.0, P = 0.0016), lower (better) Hemophilia Joint Health Scores (5.5 vs. 10.5, P = 0.0038), higher (better) Activity Scale for Kids scores (96.6 vs. 92.0, P = 0.033), more time spent in vigorous activity, and higher (better) social participation scores.

CONCLUSIONS

Our findings suggest that increasing access to clotting factor concentrates for young boys with severe haemophilia is a global imperative.

Target plasma factor levels for personalized treatment in haemophilia: a Delphi consensus statement

BACKGROUND

Prophylactic replacement with factor concentrate is the optimal treatment for persons with severe haemophilia to avoid or minimize bleeding. This ultimately prevents or reduces joint disease and improves life expectancy and quality of life towards values matching those in the normal population. However, uncertainty still exists around the optimal regimens to be prescribed for prophylaxis. An increasing number of treating physicians and patients are showing interest in patient-tailored approaches to prophylaxis, which aim to harmonize the prophylaxis regimen with the patients' bleeding phenotype, levels of physical activity and a variety of other variables.

METHODS

A modified Delphi technique was adopted to generate consensus. The expert panel met in person to set the objectives, be trained on the Delphi technique and agree on the desired level of consensus. Three iterations were used to identify the targets, the scenarios and their combinations.

RESULTS

Twenty-eight scenarios and eight target levels were identified and used to issue recommendations. The panel reached the desired level of consensus on positive or negative recommendations. Areas where consensus was not reached were identified and proposed as areas for future research. Prospective assessment of the validity of most of the proposed targets is recommended.

CONCLUSIONS

We have generated, by expert consensus, target plasma levels of factor concentrate to be used to tailor treatment for persons with haemophilia.

Pilot study of once-a-day prophylaxis for youth and young adults with severe haemophilia A

INTRODUCTION

Standard prophylaxis has been shown to be an effective treatment for severe haemophilia A. According to pharmacokinetic principles, daily factor infusions of smaller doses can maintain similar trough factor VIII (FVIII) levels, and perhaps the same protection as standard prophylaxis.

AIM

This multicentre study examined the feasibility of daily prophylaxis for youth and young adults with severe haemophilia A in Montreal and Toronto.

METHODS

Bleeding rates, joint status, quality of life and physical activity were monitored for 14 patients during this study. At baseline, subjects continued their regular treatment regimen and switched to daily prophylaxis after 4 months; nine had begun daily prophylaxis before enrolment. Additional visits occurred at 8 and 12 months which included a physical examination, inhibitor testing, HJHS and FISH assessments, the CHO-KLAT/Haemo-QoL-A and PDPAR. Treatment satisfaction was assessed using the Treatment Satisfaction Questionnaire for Medication ver.II and perceived difficulty questions at the end of study.

RESULTS AND CONCLUSIONS

There were no significant changes in quality of life except for concerns with the demanding daily infusion schedule. The number of bleeds did not statistically differ from the initial 4 months of the study to the last 8 months. Monthly bleeding rates from the year prior to the study and during the intervention phase were not statistically different. It was also found that daily prophylaxis used 24% less FVIII compared to standard prophylaxis. Taking all of this into account, we have found that providing daily prophylaxis is feasible and that it is feasible to prospectively study daily prophylaxis in youth and young adults.

Correlating clinical and radiological assessment of joints in haemophilia: results of a cross sectional study

OBJECTIVES

This study was undertaken to determine the correlation between the radiological changes in haemophilic arthropathy [X-ray, Ultrasound (US) and MRI] and clinical assessment as determined by the Hemophilia Joint Health Score (HJHS); and to document the US and MRI changes in joints that appear normal on plain X-ray and clinical evaluation.

MATERIALS AND METHODS

Of 55 study joints (22 knees and 33 ankles) in 51 patients with haemophilia/von Willebrand disease, with a median age of 15 years (range: 5-17) were assessed using X-rays (Pettersson score) and clinical examination (HJHS) at two centres (Toronto, Canada; Vellore, India). MRI and ultrasonographic scoring was done through a consensus assessment by imagers at both centres using the IPSG MRI and US scores.

RESULTS

The HJHS had a good correlation with the Pettersson score (r_s = 0.66). Though the HJHS had moderate correlation with the osteochondral component of the MRI and US scores (r_s 0.51, 0.45 respectively), its correlation with the soft tissue component was poor (r_s 0.19; 0.26 respectively). Of the 18 joints with a Pettersson score of zero, 88.9% had changes that were detected clinically by the HJHS. Osteochondral abnormalities were identified in 38.9% of these joints by the MRI, while US images of the same joints were deemed abnormal in 83.3% by the current criteria. US identified haemosiderin and other soft tissue changes in all of the joints, while the same changes were noted in 94.4% of these joints on MRI. There were four joints with a HJHS of zero, all of which had soft tissue changes on MRI (score 1-7) and US (score 2-7). Osteochondral changes were detected in three of these joints by US and in 2 by MRI. There were four joints with an MRI score of 0-1 that had significant US scores (3-5) and HJHS scores (0-6).

CONCLUSION

US and MRI are able to identify pathological changes in joints with normal X-ray imaging and clinical examination. However, further studies are required to be able to differentiate early abnormalities from normal. Clinical (HJHS) and radiological assessment (US/MRI) provide complimentary information and should be considered conjointly in the assessment of early joint arthropathy.

Generic and disease-specific quality of life among youth and young men with Hemophilia in Canada

Background

This study was undertaken to explore the longitudinal patterns of health-related quality of life (HRQoL) among youth and young adults with Hemophilia A (HA) over a 3-year period. This report presents the baseline characteristics of the study cohort.

Methods

Males, 14 to 29 years of age, with predominantly severe HA were recruited from six treatment centres in Canada. Subjects completed a comprehensive survey. HRQoL was measured using: the CHO-KLAT_2.0 (youth), Haemo-QoL-A (young adults) and the SF-36v2 (all).

Results

13 youth (mean age = 15.7, range = 12.9-17.9 years) and 33 young adults (mean age = 23.6; range = 18.4 -28.7 years) with moderate (7 %) and severe (93 %) HA were enrolled. All were on a prophylactic regimen with antihemophilic factor (Helixate FS®) during the study. The youth had minimal joint damage (mean HJHS = 5.2) compared to young adults (mean HJHS = 13.3). The mean HRQoL scores for youth were: 79.2 (SD = 11.9) for the CHO-KLAT, and 53.0 (5.5) and 52.3 (6.8) for the SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores respectively. The mean HRQoL scores for young adults were: 85.8 (9.5) for the Haemo-Qol-A, and 50.8 (6.4) and 50.9 (8.8) for PCS and MCS respectively. PCS and MCS scores were comparable to published Canadian norms, however significant differences were found for the domains of Physical Functioning and Bodily Pain. The disease-specific HRQoL scores were weakly correlated with the PCS for youth (CHO-KLAT vs. PCS r = 0.28, p = 0.35); and moderately correlated for the MCS (r = 0.39, p = 0.19). Haemo-QoL-A scores for young adults were strongly correlated with the PCS (r = 0.53, p = 0.001); and weakly correlated with the MCS (r = 0.26, p = 0.13). Joint status as assessed by HJHS was correlated with PCS scores. A history of lifelong prophylaxis resulted in better PCS but worse MCS scores.

Conclusion

Despite having hemophilia, the youth in this cohort have minimal joint disease and good HRQoL. The young adults demonstrated more joint disease and slightly worse HRQoL in the domains of physical functioning and pain. The data presented here provide new information to inform the selection of Health Related Quality of Life (HRQoL) instruments for use in future clinical trials involving persons with hemophilia.

Assessments of outcome in haemophilia - what is the added value of QoL tools?

INTRODUCTION

Access to treatment and especially to long-term regular replacement treatment with clotting factor concentrates (prophylaxis) have caused dramatic contrasts in the clinical picture between haemophilia populations. An individual patient with severe haemophilia age 20 years can have normal joints or can be severely crippled and unable to work. Assessment of outcome in a standardized way has therefore become essential.

AIM

Discuss the relevance and utility of the different outcome assessment tools in patient groups with different access to treatment.

METHODS

In the last decade new outcome assessment tools specific for haemophilia have been developed that measure all aspects of health according to the International Classification of Functioning, Disability and Health (ICF) model. These tools are directed at assessing the clinical and radiological status of joints as well as overall functioning, such as participation and psychosocial aspects, evaluating overall health-related quality of life (HRQOL). For deciding which tools to use in clinical practice or research, one needs to consider the specific context with regard to disease burden, healthcare environment and socioeconomic background of the patients being evaluated.

CONCLUSION

Prospective systematic assessment of outcome in haemophilia and related bleeding disorders is important. Based upon recent literature a critical appraisal of outcome tools is described.
