RESUMEN
INTRODUCTION: With the purpose of supporting scientific professionals and helping them to better integrate the expertise of users in their work, a users' and relatives' panel (URP) was set up at the National Institute for Excellence in Health and Social Services in Quebec (INESSS), Canada for the social services and mental health directorate. URPs are advisory structures that mobilise the experiential knowledge of people affected by various issues. OBJECTIVES: The objective of this study is to assess from a diverse stakeholders' perceptions: (1) the experience of developing and implementing the URP within the context of an Agencies for Health Technology Assessment and Assessment of Social Services (AHTAASS), (2) the contribution of such a URP, (3) the challenges encountered and (4) the perspectives of improvement for the following years. METHODOLOGY: We conducted a qualitative descriptive evaluation study. Nineteen interviews were conducted: six with URP members and 13 with staff representatives. The documents related to the creation of the panel, the URP minutes summarising the discussions and the reports published during that period were collected and analysed. Following a preliminary round of data analysis, a debriefing meeting was conducted with a few participants to validate the results. RESULTS: The panel was set up as part of the INESSS' desire to better integrate experiential knowledge into its recommendations. Twelve projects were presented to the panel on various themes. The URP enabled health professionals to consider dimensions they had not identified, to better integrate the experiential data collected from users into their work and to develop recommendations that made more sense to users. Panel members and INESSS professionals learned to work together, moving the working methods from consultation to collaboration and even coconstruction. Based on the panel's significant contribution, the INESSS decided to maintain it and to strengthen its place in its system to better integrate the experiential knowledge of users into its work. CONCLUSION: This research illustrates how AHTAASS can set up a URP composed exclusively of users, and how it can contribute and be evaluated. It shows that URPs are structures that value the sharing of experiential knowledge of its members, humanise decision-making and give meaning to the work done by scientific professionals. PATIENT OR PUBLIC CONTRIBUTION: One patient-researcher has contributed to the preparation and writing of this manuscript.

BACKGROUND: The PAROLE-Onco program was introduced in the province of Quebec, Canada in 2019. It integrates accompanying patients (APs), i.e., people who have been affected by cancer, into the clinical team as full members. These APs use their experiential knowledge with people undergoing treatment and with clinical teams. The aim of this paper is to evaluate, within the framework of two university medical centers, the perceptions of breast cancer patients who receive support from APs, particularly in terms of their active involvement in their care trajectory. METHODS: A qualitative study based on semi-structured interviews with accompanied patients was performed. Fourteen individual interviews were conducted between July and September 2021 with women presenting different profiles in terms of age, education, professional status, type of treatment, family situation, and clinical background. The data were analyzed using thematic analysis, focusing on patients' perceptions of APs' contributions and suggested improvements for accessing AP support. RESULTS: Three themes emerged from the semi-structured interviews: communication modalities used to connect patients with their APs, the characteristics of the support provided by APs, and the perceived effects of this support on the patients. Patients expressed a preference for telephone communication, highlighting its convenience and accessibility. The support provided by APs included emotional and informational support, neutrality, and adaptability. This relationship improved patient communication, reduced anxiety, helped regain control, and enhanced overall quality of life. The results emphasized the added value of APs in complementing the support offered by healthcare professionals. Patients noted the critical role of APs in helping them navigate the healthcare system, better understand their treatment processes, and manage their emotions. The ability of APs to provide practical advice and emotional reassurance was particularly valued. Overall, the findings underscored the significant impact of AP support on patients' experiences and highlighted areas for enhancing this service. CONCLUSION: This study highlights, during the care trajectory of people affected by breast cancer, APs' contribution to patients' emotional well-being because they improve, in particular, the management of emotions and communication with health professionals.
In 2019, we initiated the PAROLE-Onco program in Quebec, Canada, to support cancer patients by integrating Accompanying Patients (APs) into the medical team. These individuals, who have personally experienced cancer, join as full team members, sharing their insights with both patients and medical staff. Our study delved into the perceptions of breast cancer patients at two university hospitals regarding APs' involvement in their care trajectory. Through interviews with 14 women of diverse backgrounds and cancer experiences, we found that APs were instrumental in enhancing communication with doctors, facilitating the expression of challenging emotions, and aiding in treatment decisions. Patients valued the inclusion of APs in their care team and expressed gratitude for their support. Nonetheless, some encountered difficulties in reaching out to APs due to a lack of awareness or challenges involved in connecting. Overall, our research underscores the positive impact of involving APs in the care of breast cancer patients, and of enhancing emotional well-being and communication throughout the treatment journey.

Moral or ethical questions are vital because they affect our daily lives: what is the best choice we can make, the best action to take in a given situation, and ultimately, the best way to live our lives? Health ethics has contributed to moving ethics toward a more experience-based and user-oriented theoretical and methodological stance but remains in our practice an incomplete lever for human development and flourishing. This context led us to envision and develop the stance of a "living ethics", described in this inaugural collective and programmatic paper as an effort to consolidate creative collaboration between a wide array of stakeholders. We engaged in a participatory discussion and collective writing process known as instrumentalist concept analysis. This process included initial local consultations, an exploratory literature review, the constitution of a working group of 21 co-authors, and 8 workshops supporting a collaborative thinking and writing process. First, a living ethics designates a stance attentive to human experience and the role played by morality in human existence. Second, a living ethics represents an ongoing effort to interrogate and scrutinize our moral experiences to facilitate adaptation of people and contexts. It promotes the active and inclusive engagement of both individuals and communities in envisioning and enacting scenarios which correspond to their flourishing as authentic ethical agents. Living ethics encourages meaningful participation of stakeholders because moral questions touch deeply upon who we are and who we want to be. We explain various aspects of a living ethics stance, including its theoretical, methodological, and practical implications as well as some barriers to its enactment based on the reflections resulting from the collaborative thinking and writing process.

OBJECTIVES: Since 2018, four establishments in Quebec have been instrumental in implementing the PAROLE-Onco program, which introduced accompanying patients (APs) into healthcare teams to improve cancer patients' experience. APs are patient advisors who have acquired specific experiential knowledge related to living with cancer, using services, and interacting with healthcare professionals. They are therefore in a unique and reliable position to be able to provide emotional, informational, cognitive and navigational support to patients who are dealing with cancer. We aimed to explore APs' perspectives regarding the limiting and facilitating factors in terms of how they are integrated into the clinical oncology teams. METHODS: A qualitative study based on semi-structured interviews and focus groups was conducted with 20 APs at the beginning of their intervention (T1) and, two years later, during a second data collection (T2). Limiting and facilitating factors of APs' integration into clinical teams were analyzed in terms of governance, culture, resources and tools. RESULTS: The limited factors raised by APs to be integrated into clinical teams include the following: confusion about the specific roles played by APs, lifting the egos of certain professionals who feel they are already doing what APs typically do, lack of identification of patient needs, absence of APs in project governance organizational boundaries, and team members' availability. Various communication challenges were also raised, resulting in the program being inadequately promoted among patients. Also mentioned as limiting factors were the lack of time, space and compensation. Creating opportunities for team members to meet with APs, building trust and teaching team members how APs' activities complement theirs were enhancing factors. Other facilitators include APs being involved in decision-making committees, being leaders in promoting the PAROLE-Onco program to patients and clinical team members and creating opportunities to communicate with team members to help enhance their work and provide feedback to improve patient services. Awareness of APs' added value for the team and patients is also a key facilitator. Regarding tools, offering accompanying services by telephone allows both patients and APs to benefit from the flexibility they need. CONCLUSION: Over time, APs were able to identify optimal factors for successful implementation. Recommendations include APs and professionals working in co-construction on organization, leadership, resources and status factors. This could help catalyze a change in culture within health establishments and allow people dealing with cancer to benefit from the experiential knowledge of other patients within their clinical team.

OBJECTIVE: While patient participation in individual health technology assessments (HTAs) has been frequently described in the literature, patient and citizen participation at the organizational level is less described and may be less understood and practiced in HTA bodies. We aimed to better understand its use by describing current practice. METHOD: To elicit descriptive case studies and insights we conducted semi-structured interviews and open-ended questionnaires with HTA body staff and patients and citizens participating at the organizational level in Belgium, France, Quebec, Scotland, and Wales. RESULTS: We identified examples of organizational participation in managerial aspects: governance, defining patient involvement processes, evaluation processes and methods, and capacity building. Mechanisms included consultation, collaboration, and membership of standing (permanent) groups. These were sometimes combined. Participants were usually from umbrella patient organizations and patient associations, as well as individual patients and citizens. DISCUSSION: Although the concept, participation at the organizational level, is not well-established, we observed a trend toward growth in each jurisdiction. Some goals were shared for this participation, but HTA bodies focused more on instrumental goals, especially improving participation in HTAs, while patients and citizens were more likely to offer democratic and developmental goals beyond improving participation processes. CONCLUSION: Our findings provide rationales for organizational-level participation from the perspectives of HTA bodies and patients. The case studies provide insights into how to involve participants and who may be seen as legitimate participants. These findings may be useful to HTA bodies, the patient sector, and communities when devising an organizational-level participation framework.

BACKGROUND: Centre hospitalier de l'Université de Montréal in Canada introduced accompanying patients (APs) into the breast cancer care trajectory. APs are patients who have been treated for breast cancer and have been integrated into the clinical team to expand the services offered to people affected by cancer. This study describes the profiles of the people who received the support and explores whether one-offs vs ongoing encounters with APs influence their experience of care, on self-efficacy in coping with cancer, and on their level of psychological distress. METHODS: An exploratory cross-sectional study was carried out among patients to compare patients who had one encounter with an AP (G1) with those who had had several encounters (G2). Five questionnaires were administered on socio-demographic characteristics, care pathway, evaluation of the support experience, self-efficacy in coping with cancer, and level of psychological distress. Logbooks, completed by the APs, determined the number of encounters. Linear regression models were used to evaluate the associations between the number of encounters, patient characteristics, care pathway, number of topics discussed, self-efficacy measures in coping with cancer, and level of psychological distress. RESULTS: Between April 2020 and December 2021, 60% of 535 patients who were offered support from an AP accepted. Of these, one hundred and twenty-four patients participated in the study. The study aimed to recruit a minimum of 70 patients with the expectation of obtaining at least 50 participants, assuming a response rate of 70%. There were no differences between G1 and G2 in terms of sociodemographic data and care pathways. Statistical differences were found between G1 and G2 for impacts on and the return to daily life (p = 0.000), the return to the work and impacts on professional life (p = 0.044), announcement of a diagnosis to family and friends (p = 0.033), and strategies for living with treatment under the best conditions (p = 0.000). Significant differences were found on the topics of cancer (p = 0.000), genetic testing (p = 0.023), therapeutic options (p = 0.000), fatigue following treatment (p = 0.005), pain and discomfort after treatment or surgery (p = 0.000), potential emotions and their management (p = 0.000) and the decision-making processes (p = 0.011). A significant relationship was found between the two groups for patients' ability to cope with cancer (p = 0.038), and their level of psychological distress at different stages of the care pathway (p = 0.024). CONCLUSIONS: This study shows differences between one-time and ongoing support for cancer patients. It highlights the potential for APs to help patients develop self-efficacy and cope with the challenges of cancer treatment.

INTRODUCTION: Since 2018, four establishments in Quebec, Canada, have decided to implement the PAROLE-Onco programme, which introduced accompanying patients (APs) in healthcare teams to improve the experience of cancer patients. APs are patient advisors who have had a cancer treatment experience and who conduct consultations to complement the service offered by providing emotional, informational and educational support to patients undergoing treatments (e.g., radiotherapy, chemotherapy, surgery), mostly for breast cancer. We aimed to explore the evolution of APs' perspectives regarding their activities within the clinical oncology teams as well as the perceived effects of their intervention with patients, the clinical team and themselves. METHODS: A qualitative study based on semistructured interviews and focus groups was conducted with APs at the beginning of their intervention (T1) and 2 years afterwards (T2). The themes discussed were APs' activities and the perceived effects of their interventions on themselves, on the patients and on the clinical team. RESULTS: In total, 20 APs were interviewed. In T2, APs' activities shifted from listening and sharing experiences to empowering patients by helping them become partners in their care and felt generally more integrated into the clinical team. APs help patients feel understood and supported, alleviate stress and become partners in the care they receive. They also alleviate the clinical team's workload by offering a complementary service through emotional support, which, according to them, helps patients feel calmer and more prepared for their appointments with healthcare professionals. They communicate additional information about their patients' health journey, which makes the appointment more efficient for healthcare professionals. When APs accompany patients, they feel as if they can make a difference in patients' lives. Their activities are perceived by some as an opportunity to give back but also as a way of giving meaning to their own experience, in turn serving as a learning experience. CONCLUSION: By mobilizing their experiential knowledge, APs provide emotional, informational, cognitive and navigational support, which allows patients to be more empowered in their care and which complements professionals' scientific knowledge, thereby helping to refine their sensitivity to the patients' experiences. PATIENT OR PUBLIC CONTRIBUTION: Two patient-researchers have contributed to the study design, the conduct of the study, the data analysis and interpretation, as well as in the preparation and writing of this manuscript.

INTRODUCTION: Evaluating rare disease interventions poses challenges for HTA agencies, including uncertainties and ethical issues and tensions. INESSS has recently adopted a Statement of Principles and Ethical Foundations which proposes a multidimensional approach to value appraisal as well as five principles to frame the evaluation process. AREAS COVERED: Our aim was to identify and analyze HTA challenges for appraising interventions for rare diseases, using the Statement's approach to value appraisal as an analytical framework, and outline how the Statement's principles can help address these challenges. Challenges, covering a diversity of aspects, were identified by leveraging institutional experience in diverse domains of expertise and consolidated through narrative literature review. Challenges were categorized by value dimension (clinical, populational, economic, organizational, and sociocultural), which allowed to pinpoint how each challenge affects the ability to appraise the value of an intervention. Key ethical tensions across dimensions were also identified. Specific approaches to addressing these challenges - related to knowledge mobilization and integration, deliberation, and recommendation-making - were outlined on the basis of the principles promulgated in the Statement. EXPERT OPINION: A multidimensional approach can be fruitful for analyzing challenges for appraising the value of rare disease interventions and help guide approaches to tackle them.

In recent years, recognizing patients' experiential knowledge to improve the quality of care has resulted in the participation of patient advisors at various levels of healthcare systems. Some who are working at the clinical level are called accompanying patients (AP). A PRISMA-ScR exploratory scoping review of the literature was conducted on articles published from 2005 to 2021. Articles not in English or French and grey literature were excluded. The databases searched included Medline, PubMed, Scopus, and Google Scholar. The data were organized according to the similarities in the ethical foundations of the included papers. Out of 2095 identified papers, 8 met inclusion criteria. Terms used to describe APs included peer support, resource parent, and peer health mediator. The clinical settings included psychiatry/mental health and neonatology. APs, patients, healthcare professionals, managers and policy makers were included in the studies. Three personal ethical foundations describing the foundations of the AP role were found: resilience, listening skills and altruism. The ethical foundations of this role also addressed interpersonal and interprofessional relationships with other actors in the healthcare system. The literature on the ethical foundations of APs is sparse, with heterogeneous methodologies. Further studies mobilizing well-defined methodologies would further validate the current results and deepen our understanding of the ethical foundations of the AP role.
RESUMEN
The application of artificial intelligence (AI) may revolutionize the healthcare system, leading to enhance efficiency by automatizing routine tasks and decreasing health-related costs, broadening access to healthcare delivery, targeting more precisely patient needs, and assisting clinicians in their decision-making. For these benefits to materialize, governments and health authorities must regulate AI, and conduct appropriate health technology assessment (HTA). Many authors have highlighted that AI health technologies (AIHT) challenge traditional evaluation and regulatory processes. To inform and support HTA organizations and regulators in adapting their processes to AIHTs, we conducted a systematic review of the literature on the challenges posed by AIHTs in HTA and health regulation. Our research question was: What makes artificial intelligence exceptional in HTA? The current body of literature appears to portray AIHTs as being exceptional to HTA. This exceptionalism is expressed along 5 dimensions: 1) AIHT's distinctive features; 2) their systemic impacts on health care and the health sector; 3) the increased expectations towards AI in health; 4) the new ethical, social and legal challenges that arise from deploying AI in the health sector; and 5) the new evaluative constraints that AI poses to HTA. Thus, AIHTs are perceived as exceptional because of their technological characteristics and potential impacts on society at large. As AI implementation by governments and health organizations carries risks of generating new, and amplifying existing, challenges, there are strong arguments for taking into consideration the exceptional aspects of AIHTs, especially as their impacts on the healthcare system will be far greater than that of drugs and medical devices. As AIHTs begin to be increasingly introduced into the health care sector, there is a window of opportunity for HTA agencies and scholars to consider AIHTs' exceptionalism and to work towards only deploying clinically, economically, socially acceptable AIHTs in the health care system.
RESUMEN
Since the beginning of the COVID-19 pandemic, numerous studies have been conducted to identify interventions that could contribute to alleviating the burden it has caused. The Institut national d'excellence en santé et en services sociaux (INESSS) has played a key role in informing the government of Québec regarding the evaluation of specific pandemic-related interventions. This process took place in a context characterized by a sense of urgency to assess and recommend potential interventions that could save lives and reduce the effects of the disease on populations and healthcare systems, which increased the pressure on the regulatory agencies leading these evaluations. While some of the interventions examined were considered promising, results from COVID-19 studies often led to uncertainty regarding their efficacy or safety. Regulatory agencies evaluating the value of promising interventions thus face challenges in deciding whether these should be made available to the population, particularly when assessing their benefit-risk balance. To shed light on these challenges, we identified underlying ethical considerations that can influence such an assessment. A rapid literature review was conducted in February 2021, to identify the main challenges associated with the benefit-risk balance assessment of promising interventions. To reinforce our understanding of the underlying ethical considerations, we initiated a discussion among various social actors involved in critical thinking surrounding the evaluation of promising interventions, including ethicists, clinicians and researchers involved in clinical or public health practice, as well as patients and citizens. This discussion allowed us to create a space for exchange and mutual understanding among these various actors who contributed equally to the identification of ethical considerations. The knowledge and perspectives stemming from the scientific literature and those consulted were integrated in a common reflection on these ethical considerations. This allowed patients and citizens, directly affected by the evaluation of pandemic-related interventions and the resulting social choices, to contribute to the identification of the relevant ethical considerations. It also allowed for reflection on the responsibilities of the various actors involved in the development, evaluation, and distribution of promising interventions in a setting of urgency and uncertainty, such as that brought about by the COVID-19 pandemic.
RESUMEN
CONTEXT: The Ministry of Health in Québec requested the National Institute of Excellence in Health and Social Services to produce clinical and implementation recommendations for the prophylaxis, diagnosis, and treatment of Lyme disease. OBJECTIVES: (i) Describe the process of trialing different modalities of patient engagement as a means to integrate a diversity of patient perspectives and (ii) Describe the learning process of INESSS regarding the integration of the patient perspective. METHODOLOGY: All documents were analyzed, and a survey with all advisory committee members and semi-structured interviews with stakeholders were conducted. Each interview was transcribed verbatim and imported into QDA miner software for the purposes of analysis. Data analysis was carried out concurrently with data collection to allow for an iterative approach between data collection and analysis. RESULTS: Five methods to integrate the perspectives of patients were used: (i) interviews with patients, (ii) inclusion of patient partners within the advisory committee, (iii) literature review, (iv) focus groups with one patient association, and (v) feedback from patient associations on recommendations intended for decision makers and other targeted stakeholders. The patient partners influenced decisions by sharing their experiential knowledge. The patient interviews and the literature review added an in-depth perspective on the disease and experience with the healthcare system. The patient association members shared their perspectives and helped disseminate the recommendation to sustain a practice change. CONCLUSION: The combination of methods to collect and integrate patients' knowledge and patient associations' perspectives helped develop a comprehensive understanding of a controversial object of evaluation.

OBJECTIVES: Increasing emphasis is given on involving patients in health technology assessment (HTA). While this is mainly done at the level of regional and national HTA agencies, this tendency is also emerging in local HTA units. In this study, we provide the results of a survey conducted in local HTA units in the province of Quebec, Canada. The aim of the survey was to provide an overview of local HTA unit practices to involve patients, users, caregivers, and citizens in their process, their interest in doing so, and their information needs for this. METHODS: The survey was conducted in 2017 with a response rate of eleven units over a possibility of twelve. RESULTS: Three units out of eleven (27.3 percent) never involved patients or members of the public in their processes and all indicated that they will involve them in the next few years. The three most important needs for support identified in the HTA units were in: recruiting and selecting patients; integrating experiential knowledge; and knowing and implementing the best methods and practices for partnership. CONCLUSION: Patient involvement in local HTA units is quickly evolving and that is why they urgently need tools to involve more effectively patients and members of the public in their process.

CONTEXT: The National Institute of Excellence in Health and Social Services (INESSS), which functions as the Québec health technology assessment (HTA) agency, tested a new way to engage patients along with health-care professionals in the co-construction of recommendations regarding implantable cardioverter-defibrillator replacement. OBJECTIVE: The objective of this article was to describe the process of co-construction of recommendations and to propose methods of building best practices for patient involvement (PI) in HTA. DESIGN: Throughout the process, documents were collected and participant observations were made. Individual interviews were conducted with patients, health-care professionals and the INESSS scientific team, from January to March 2018. RESULTS: Three committees were established: an expert patient committee to reflect on patient experience literature; an expert health professional committee to reflect on medical literature; and a co-construction committee through which both patients and health-care professionals contributed to develop the recommendations. The expert patients validated and contextualized a literature review produced by the scientific team. This allowed the scientists to consider aspects related to the patient experience and to integrate the feedback from patients into HTA recommendations. The most important factor contributing to a positive PI experience was the structured methodology for selecting patient participants, and a key factor that inhibited the process was a lack of training in PI on the part of the scientific team. CONCLUSIONS: This experience demonstrates that it is possible to co-construct recommendations, even for technically complex HTA subjects, through a more democratic process than usual which led to more patient-focused guidance.

Most cardiovascular traits of interest can be defined as "complex traits," with the first step in the identification of genetic factors affecting such traits being the detection of quantitative trait loci (QTLs). Animal models have proven particularly useful in this regard. However, only very few of the QTLs identified to date have led to the identification of candidate genes. We describe an example of our own work where the combination of anatomical and a biochemical intermediate phenotypes have led to the identification of the natriuretic peptide precursor A (Nppa) gene as a candidate gene for left ventricular hypertrophy (LVH). Combined with the power of comparative genetics, these strategies will continue to improve the chances of finding candidate genes for cardiovascular traits such as susceptibility to heart diseases, hypertension, and hypertension-induced end-organ damage.
