[The use of medical imaging as a therapeutic patient education tool in radiotherapy : a feasibility study]. / L'utilisation de l'imagerie médicale en tant qu'outil d'éducation thérapeutique du patient en radiothérapie : étude de faisabilité.

Because of its prevalence and high mortality rate, cancer is a major public health challenge. Radiotherapy is an important treatment option, and makes extensive use of medical imaging. Until now, this type of tool has been reserved to professionals, but it is now opening up to wider use, including by patients themselves for educational purposes. However, this type of usage has been little explored so far. An experimental feasibility study was carried out in the radiotherapy department of the University Hospital of Liège on adult patients with cancer or pulmonary metastases, assigned to two randomized groups. In addition to the usual information given by the radiotherapist, the patients of the experimental group benefited from an intervention consisting in the 3D visualization of their own medical images via the free and open-source computer software «Stone of Orthanc¼. The study results show a low refuse rate (8.2 %) for the 15 patients recruited. Although non-significant, the experimental group showed a median gain in global perception of knowledge, a decrease in anxiety scores and emotional distress. A significant reduction (p = 0.043) was observed for the depression score. The positive results of the feasibility study encourage further work and reinforce the positioning of medical imaging as a tool for therapeutic patient education.

De par sa fréquence et son taux de mortalité élevé, le cancer représente un problème de santé publique majeur. Parmi les traitements possibles, la radiothérapie tient une place importante et fait appel massivement à l'imagerie médicale. Jusqu'ici réservé aux professionnels, ce type d'outil s'ouvre à un usage plus large, y compris par le patient lui-même dans une perspective éducative. Mais cette utilisation est restée peu explorée jusqu'à présent. Une étude expérimentale de faisabilité a ainsi été menée au sein du service de Radiothérapie du CHU de Liège sur des patients adultes avec cancer ou métastases pulmonaires, répartis en deux groupes randomisés. En plus des informations habituellement données par le radiothérapeute, le groupe expérimental a bénéficié d'une intervention consistant en la visualisation en 3D de ses propres images médicales via le logiciel libre et open-source «Stone of Orthanc¼. Les résultats de l'étude indiquent un taux de refus faible (8,2 %) pour les 15 patients recrutés. Bien que non significatif, le groupe expérimental a montré, par rapport au groupe contrôle, un gain médian dans la perception globale de connaissances ainsi qu'une diminution des scores liés à l'anxiété et à la détresse émotionnelle. Une réduction significative (p = 0,043) est observée pour le score de dépression. Les résultats positifs de l'étude de faisabilité encouragent la poursuite des travaux et renforcent le positionnement de l'usage de l'imagerie médicale en tant qu'outil d'éducation thérapeutique du patient.

General practitioners' well-being in Belgium: results from the cross-sectional PRICOV-19 study.

BACKGROUND: The mental health and well-being of GPs is a critical issue as they play a vital role in providing healthcare services to individuals and communities. Research has shown that GPs often face high levels of stress, burnout, and mental health problems due to their demanding work environment. During the COVID-19 pandemic, GPs faced additional challenges which further impacted their mental health and well-being. This study aims to investigate the impact of systemic work-related stressors on the level of well-being of GPs in Belgium during the pandemic, with a particular emphasis on identifying regional variations between Flanders, Wallonia, and Brussels-Capital. METHODS: Data were collected with a self-reported online questionnaire from 479 GPs Belgian practices between December 2020 and August 2021 as part of the international PRICOV-19 study that explored the organization of general practices during COVID-19 in 38 countries to guarantee safe, effective, patient-centered, and equitable care. Well-being was evaluated by the Mayo Clinic's expanded 9-item well-being index. RESULTS: The findings of this study reveal notable regional discrepancies in the degree of well-being experienced by Belgian GPs, with the Walloon region displaying the lowest level of well-being (37%) in a population highly susceptible to professional distress (57%). Among the key stressors contributing to such distress, financial difficulties among patients (p < 0.011), the fee-for-service payment system (p = 0.013), a lack of work-related purpose (p = 0.047), and inadequate work-life balance (p < 0.001) were identified as significant factors. When examining the influence of regional disparities, it was found that the sole significant interaction between work-related stressors and region regarding the probability of experiencing distress was related to the possibility of workload sharing among practice personnel. CONCLUSION: The findings from this study underscore the imperative for more comprehensive research aimed at scrutinizing the differences in well-being across the three regions in Belgium and identifying the systemic factors that influence the practice environment, as opposed to exclusively concentrating on enhancing individual resilience.

Characteristics of primary care practices associated with patient education during COVID-19: results of the cross-sectional PRICOV-19 study in 38 countries.

BACKGROUND: In response to the COVID-19 pandemic, the World Health Organization established a number of key recommendations such as educational activities especially within primary care practices (PCPs) which are a key component of this strategy. This paper aims to examine the educational activities of PCPs during COVID-19 pandemic and to identify the factors associated with these practices across 38 countries. METHODS: A "Patient Education (PE)" score was created based on responses to six items from the self-reported questionnaire among PCPs (n = 3638) compiled by the PRICOV-19 study. Statistical analyses were performed on 3638 cases, with PCPs with missing PE score values were excluded. RESULTS: The PE score features a mean of 2.55 (SD = 0.68) and a median of 2.50 (2.16 - 3.00), with a maximum of 4.00, and varies quite widely between countries. Among all PCPs characteristics, these factors significantly increase the PE score: the payment system type (with a capitation payment system or another system compared to the fee for service), the perception of average PCP with patients with chronic conditions and the perception of adequate governmental support. CONCLUSION: The model presented in this article is still incomplete and requires further investigation to identify other configuration elements favorable to educational activities. However, the results already highlight certain levers that will enable the development of this educational approach appropriate to primary care.

Outreach work in Belgian primary care practices during COVID-19: results from the cross-sectional PRICOV-19 study.

BACKGROUND: General practitioners (GPs) have a vital role in reaching out to vulnerable populations during and after the COVID-19 pandemic. Nonetheless, they experience many challenges to fulfill this role. This study aimed to examine associations between practice characteristics, patient population characteristics and the extent of deprivation of practice area on the one hand, and the level of outreach work performed by primary care practices (PCPs) during the COVID-19 pandemic on the other hand. METHODS: Belgian data from the international PRICOV-19 study were analyzed. Data were collected between December 2020 and August 2021 using an online survey in PCPs. Practices were recruited through randomized and convenience sampling. Descriptive statistics and ordinal logistic regression analyses were performed. Four survey questions related to outreach work constitute the outcome variable. The adjusted models included four practice characteristics (practice type, being a teaching practice for GP trainees; the presence of a nurse or a nurse assistant and the presence of a social worker or health promotor), two patient population characteristics (social vulnerability and medical complexity) and an area deprivation index. RESULTS: Data from 462 respondents were included. First, the factors significantly associated with outreach work in PCPs are the type of PCP (with GPs working in a group performing more outreach work), and the presence of a nurse (assistant), social worker or health promotor. Second, the extent of outreach work done by a PCP is significantly associated with the social vulnerability of the practice's patient population. This social vulnerability factor, affecting outreach work, differed with the level of medical complexity of the practice's patient population and with the level of deprivation of the municipality where the practice is situated. CONCLUSIONS: In this study, outreach work in PCPs during the COVID-19 pandemic is facilitated by the group-type cooperation of GPs and by the support of at least one staff member of the disciplines of nursing, social work, or health promotion. These findings suggest that improving the effectiveness of outreach efforts in PCPs requires addressing organizational factors at the practice level. This applies in particular to PCPs having a more socially vulnerable patient population.

Quality of care in Belgian general practices during the COVID-19 pandemic: results of the cross-sectional PRICOV-19 study.

BACKGROUND: The COVID-19 pandemic immensely impacted care provision, including quality of care in general practice. This paper aimed: (1) to assess how Belgian general practices acted upon the six dimensions of quality of care during COVID-19; (2) to study differences between the three Belgian regions; and (3) to benchmark the performance of the Belgian practices against the performance in other European countries. METHODS: The data collected from 479 Belgian practices during 2020-2021 using an online survey as part of the international cross-sectional PRICOV-19 study were analyzed.  Hereby, descriptive statistics, chi-squared tests, and binary logistic regression analyses were performed. Thirty-four survey questions related to the six dimensions of quality of care were selected as outcome variables. The adjusted regression models included four practice characteristics as covariates: practice type, being a teaching practice for GP trainees, multidisciplinarity of the team, and payment system. RESULTS: Belgian practices made important organizational changes to deliver high-quality care during COVID-19. Most practices (n = 259; 56.1%) actively reached out to vulnerable patients. Limitations to the practice building or infrastructure threatened high-quality care in 266 practices (55.5%). Infection prevention measures could not always be implemented during COVID-19, such as using a cleaning protocol (n = 265; 57.2%) and providing a separate doctor bag for infection-related home visits (n = 130; 27.9%). Three hundred and sixty practices (82.0%) reported at least one safety incident related to a delayed care process in patients with an urgent condition. The adjusted regression analysis showed limited significant differences between the Belgian regions regarding the quality of care delivered. Belgian practices demonstrated varied performance compared to other European countries. For example, they excelled in always checking the feasibility of isolation at home but reported more patient safety incidents related to timely care than at least three-quarters of the other European countries. CONCLUSIONS: Future studies using different design methods are crucial to investigate which country and practice characteristics are associated with delivering high-quality care.

Evidence for 2 clusters among patients with noneosinophilic asthma.

BACKGROUND: Although asthma is often seen as an eosinophilic disease associated with atopy, patients with noneosinophilic asthma represent a substantial part of the population with asthma. OBJECTIVE: To apply an unsupervised clustering method in a cohort of 588 patients with noneosinophilic asthma (sputum eosinophils < 3%) recruited from an asthma clinic of a secondary care center. METHODS: Our cluster analysis of the whole cohort identified 2 subgroups as cluster 1 (n = 417) and cluster 2 (n = 171). RESULTS: Cluster 1 comprised a predominantly female group with late disease onset, a low proportion of atopy (24%), and a substantial smoking history (53%). In this cluster, treatment burden was low (<50% of inhaled corticosteroid users); asthma control and quality of life were poor, with median Asthma Control Test, Asthma Control Questionnaire, and Asthma Quality of Life scores of 16, 1.7, and 4.5, respectively, whereas lung function was preserved with a median postbronchodilation forced expiratory volume in 1 second of 93% predicted. Cluster 2 was a predominantly male group, almost exclusively comprising patients with atopy (99%) with early disease onset and a moderate treatment burden (median inhaled corticosteroids dose 800 µg/d equivalent beclomethasone). In cluster 2, asthma was partially controlled, with median Asthma Control Test and Asthma Control Questionnaire scores reaching 18 and 1.3, respectively, and lung function well preserved with a median postbronchodilation of 95% predicted. Although systemic and airway neutrophilic inflammation was the dominant pattern in cluster 1, cluster 2 essentially comprised paucigranulocytic asthma with moderately elevated fraction exhaled nitric oxide. CONCLUSION: Noneosinophilic asthma splits into 2 clusters distinguishing by disease onset, atopic status, smoking history, systemic and airway inflammation, and disease control and quality of life.

Impairment of EQ-5D-5L Domains According to Allergic Rhinitis and Asthma Control: A MASK-air Real-World Study.

BACKGROUND: EQ-5D-5L (EuroQOL, 5 Domains, 5 Levels) is a widely used health-related quality-of-life instrument, comprising 5 domains. However, it is not known how each domain is impacted by rhinitis or asthma control. OBJECTIVE: To assess the association between rhinitis or asthma control and the different EQ-5D-5L domains using data from the MASK-air mHealth app. METHODS: In this cross-sectional study, we assessed data from all MASK-air users (2015-2021; 24 countries). For the levels of each EQ-5D-5L domain, we assessed rhinitis and asthma visual analog scales (VASs) and the combined symptom-medication score (CSMS). We built ordinal multivariable models assessing the adjusted association between VAS/CSMS values and the levels of each EQ-5D-5L domain. Finally, we compared EQ-5D-5L data from users with rhinitis and self-reported asthma with data from users with rhinitis alone. RESULTS: We assessed 5354 days from 3092 users. We observed an association between worse control of rhinitis or asthma (higher VASs and CSMS) and worse EQ-5D-5L levels. In multivariable models, all VASs and the CSMS were associated with higher levels of pain/discomfort and daily activities. For anxiety/depression, the association was mostly observed for rhinitis-related tools (VAS nose, VAS global, and CSMS), although the presence of self-reported asthma was also associated with worse anxiety/depression. Worse mobility ("walking around") was particularly associated with VAS asthma and with the presence of asthma. CONCLUSIONS: A worse rhinitis control and a worse asthma control are associated with higher EQ-5D-5L levels, particularly regarding pain/discomfort and activity impairment. Worse rhinitis control is associated with worse anxiety/depression, and poor asthma control with worse mobility.

Monitoring Surveys in the Context of Covid-19, Published in Belgium and France, in the Light of Health Democracy.

Introduction: The management of a pandemic, such as COVID-19, requires the full participation of citizens. This recent situation has revealed the undermining of user participation in the decision-making process. Thus, this study aims to assess the involvement of users in the design and administration of surveys for health crisis monitoring and to stimulate reflection on information processes shared upstream during the decision-making process. Methods: A literature search was conducted on population monitoring surveys published during the first containment period in Belgium and France between April and May 2020. The selected studies were first analyzed according to a reading grid based on the criteria proposed by the World Health Organization (WHO) for monitoring populations and supplemented by data from a descriptive analysis of the selected studies. Second, with the objective of specifically evaluating the involvement of users in monitoring surveys, this study evaluated the surveys according to the following parameters: content of a study based on themes presented in surveys; inclusion of health literacy (HL); and factors of commitment of the respondents to the survey. Results: A total of 45 studies were selected for final analysis. The majority of the surveys focused on the effect of COVID-19 on well-being. Furthermore, analysis indicated that, in summary, the HL of people concerned as well as the involvement of respondents is poorly considered, which remains limited in terms of the design and administration of the surveys. Discussion: Although the principles of health democracy seemed to have been established, the exceptional regime induced by the epidemic overlooked the observance of such principles. This result indicates the need to reconsider the participation of citizens as real partners in care, including health crisis management.

[Dyspnea «sine materia¼]. / La dyspnée «sine materia¼.

Dyspnea is a symptom of respiratory discomfort commonly encountered in clinical practice which, in most of the cases, relates to a cardiopulmonary or a metabolic disorder. Its genesis is complex and results from numerous interactions within cortical and limbic brain areas following intero- and nociceptive stimuli. The term dyspnea «sine materia¼ points to a state where no clear underlying cardiopulmonary or metabolic pathology has been identified and we include here the hyperventilation syndrome and the physical deconditioning. Treatment of dyspnea «sine materia¼ is based on behavioural psychotherapy and on reathtletisation programme in case of physical deconditioning.

La dyspnée est un symptôme d'inconfort respiratoire extrêmement courant en médecine qui traduit, le plus souvent, un désordre cardiorespiratoire ou métabolique. Sa genèse est complexe et résulte de l'intégration, au niveau du cortex et du système limbique, de messages intéro- et nociceptifs. Par dyspnée «sine materia¼, nous entendons ici une dyspnée sans pathologie cardiorespiratoire ou métabolique sous-jacente avérée et nous y incluons celle du syndrome d'hyperventilation et du déconditionnement physique. La prise en charge de la dyspnée «sine materia¼ et, notamment, celle du syndrome d'hyperventilation repose sur la psychothérapie comportementale et la gestion du déconditionnement physique par des programmes de réathlétisation.

The use of patient-reported outcome measures by healthcare professionals in specialized asthma management centers in French-speaking Belgium: A mixed-methods study.

INTRODUCTION: Recently, the literature has promoted the use of patient-reported outcome measures (PROMs) in clinical practice as a means to foster patient engagement. However, conditions necessary to support the use of PROMs to encourage asthma patient engagement are not clearly defined. Therefore, we sought (1) to explore the current and ideal use of PROMs by healthcare professionals (HP) in specialized asthma management centers in French-speaking Belgium and (2) to understand under which conditions the use of PROMs contributes to patient engagement. METHODS: We undertook a mixed-methods study with both anonymous online survey and in-person qualitative semi-structured interviews conducted with HPs to understand their perspectives on the routine use of PROMs. HPs were recruited from 16 asthma centers (French-speaking Belgium) identified via the Belgian Respiratory Society. RESULTS: Of the 170 HPs identified from the 16 participating centers, 51 (30%) responded to the survey (n = 51) and 11 completed semi-structured interviews. 53% (27/51) of the surveyed HPs reported using PROMs primarily for asthma monitoring and clinical research while all reported that PROMs should primarily be used in practice to facilitate communication with the patient and to address neglected aspects of the care relationship such as the psychosocial aspects of the disease. The qualitative interviews revealed avenues for moving from a medical-centered and utilitarian use of PROMs to a use serving patient engagement. This would require HPs to go beyond their current representation of PROMs, to use instruments offering a more holistic image of the patient, to incorporate PROMs into a digital tool and to integrate PROMs in a patient education process. CONCLUSION: The main findings of this study suggest relevant avenues for using PROMs in ways that support patient engagement.

Development and validation of a predictive model combining patient-reported outcome measures, spirometry and exhaled nitric oxide fraction for asthma diagnosis.

Introduction: Although asthma is a common disease, its diagnosis remains a challenge in clinical practice with both over- and underdiagnosis. Here, we performed a prospective observational study investigating the value of symptom intensity scales alone or combined with spirometry and exhaled nitric oxide fraction (F ENO) to aid in asthma diagnosis. Methods: Over a 38-month period we recruited 303 untreated patients complaining of symptoms suggestive of asthma (wheezing, dyspnoea, cough, sputum production and chest tightness). The whole cohort was split into a training cohort (n=166) for patients recruited during odd months and a validation cohort (n=137) for patients recruited during even months. Asthma was diagnosed either by a positive reversibility test (≥12% and ≥200 mL in forced expiratory volume in 1 s (FEV1)) and/or a positive bronchial challenge test (provocative concentration of methacholine causing a 20% fall in FEV1 ≤8 mg·mL-1). In order to assess the diagnostic performance of symptoms, spirometric indices and F ENO, we performed receiver operating characteristic curve analysis and multivariable logistic regression to identify the independent factors associated with asthma in the training cohort. Then, the derived predictive models were applied to the validation cohort. Results: 63% of patients in the derivation cohort and 58% of patients in the validation cohort were diagnosed as being asthmatic. After logistic regression, wheezing was the only symptom to be significantly associated with asthma. Similarly, FEV1 (% pred), FEV1/forced vital capacity (%) and F ENO were significantly associated with asthma. A predictive model combining these four parameters yielded an area under the curve of 0.76 (95% CI 0.66-0.84) in the training cohort and 0.73 (95% CI 0.65-0.82) when applied to the validation cohort. Conclusion: Combining a wheezing intensity scale with spirometry and F ENO may help in improving asthma diagnosis accuracy in clinical practice.

Predictors of change in asthma-related quality of life: a longitudinal real-life study in adult asthmatics.

PURPOSE: Asthma negatively impacts health-related quality of life (HRQL). The objective is to investigate the longitudinal relationship between HRQL in asthma and disease control, demographic and clinical objective parameters in an adult population in real-life settings. METHODS: We conducted a longitudinal study on adult asthmatics recruited from Liege University Hospital Asthma Clinic (Belgium) between 2011 and 2019. We selected those who had two visits and completed two patient-reported outcome measures (PROMs), the asthma control test (ACT) and the mini asthma quality of life questionnaire (AQLQ) (n = 290). AQLQ was the dependent variable. Demographic, functional and inflammatory characteristics, asthma control, and exacerbations were the independent variables. We applied generalized linear mixed models to identify the factors associated with change in AQLQ and its dimensions. RESULTS: Median (IQR) time interval between the two visits was 7 (5-19) months. Overall, median (IQR) global AQLQ increased from 4.1 (3-5.1) to 4.6 (3.4-5.9) (p < 0.0001). All AQLQ dimensions significantly improved, apart the environmental one. AQLQ improved in patients who had both step-up and step-down pharmacological treatment as well as in patients reporting no change between the two visits. The fitted models indicated that change in ACT was the main predictor of change in AQLQ (p < 0.0001). A rise in 3 units in ACT predicted an improvement of 0.5 AQLQ (AUC-ROC = 0.85; p < 0.0001). Change in BMI inversely impacted global AQLQ (p < 0.01) and its activity dimension (p < 0.0001). CONCLUSION: Asthma control and BMI are key predictors of asthma quality of life acting in an opposite direction. AQLQ may improve without step-up in the pharmacological treatment.

How respiratory symptoms impact asthma-related quality of life in mild asthmatics.

Many studies exploring the factors associated with asthma-specific quality of life (QOL) have shown that asthma control is the main predictor of asthma-related QOL. However, to the best of our knowledge, no study has ever explored the individual impact of the five main symptoms of asthma (wheezing, dyspnea, chest tightness, cough and airway secretion) reported directly by the patient on asthma-related QOL. A cross-sectional study was conducted on untreated adult (≥18 years) asthmatics recruited from the Liege University Hospital Asthma Clinic (Belgium) for asthma diagnosis confirmation between 2018 and 2021 (n = 171). Multiple linear regression analysis demonstrated that dyspnea and chest tightness were the two leading factors associated with asthma-related QOL in a population of mild asthma.

Self-esteem and learning dynamics in nursing students: An existential-phenomenological study.

AIM: To describe nursing student self-esteem changes over time and its impacts on learning strategies. DESIGN: Existential phenomenology. METHODS: Interviews were conducted in Spring 2018 in a purposive sample of 39 nursing students, exploring events critical to self-esteem and their impacts. Transcriptions were analysed descriptively and interpretatively to decipher the process that links self-esteem, events and learning behaviour. RESULTS: What led to self-esteem changes were "relationships with nurses during internships" and "receiving evaluations." The students interpreted events and drew conclusions about their aptitude for nursing, which in turn prompted proactive or defensive learning behaviours. Their interpretations both depended on their self-esteem and impacted it, in a vicious or virtuous circle. Exploring self-esteem allows a better understanding of the importance of students' relationships with nursing teams, and of some of their defensive behaviours. Understanding the role of nursing student self-esteem in the learning process could help improve student well-being and competence.

Developing evaluation capacities in integrated care projects: Lessons from a scientific support mission implemented in Belgium.

The capacity of self-assessment, to learn from experience, to make information-based decisions, and to adapt over time are essential drivers of success for any project aiming at healthcare system change. Yet, many of those projects are managed by healthcare providers' teams with little evaluation capacity. In this article, we describe the support mission delivered by an interdisciplinary scientific team to 12 integrated care pilot projects in Belgium, mobilizing a set of tools and methods: a dashboard gathering population health indicators, a significant event reporting method, an annual report, and the development of a sustainable "learning community." The article provides a reflexive return on the design and implementation of such interventions aimed at building organizational evaluation capacity. Some lessons were drawn from our experience, in comparison with the broader evaluation literature: The provided support should be adapted to the various needs and contexts of the beneficiary organizations, and it has to foster experience-based learning and requires all stakeholders to adopt a learning posture. A long-time, secure perspective should be provided for organizations, and the availability of data and other resources is an essential precondition for successful work.

Has the COVID-19 Pandemic Led to Changes in the Tasks of the Primary Care Workforce? An International Survey among General Practices in 38 Countries (PRICOV-19).

The COVID-19 pandemic has had a large and varying impact on primary care. This paper studies changes in the tasks of general practitioners (GPs) and associated staff during the COVID-19 pandemic. Data from the PRICOV-19 study of 5093 GPs in 38 countries were used. We constructed a scale for task changes and performed multilevel analyses. The scale was reliable at both GP and country level. Clustering of task changes at country level was considerable (25%). During the pandemic, staff members were more involved in giving information and recommendations to patients contacting the practice by phone, and they were more involved in triage. GPs took on additional responsibilities and were more involved in reaching out to patients. Problems due to staff absence, when dealt with internally, were related to more task changes. Task changes were larger in practices employing a wider range of professional groups. Whilst GPs were happy with the task changes in practices with more changes, they also felt the need for further training. A higher-than-average proportion of elderly people and people with a chronic condition in the practice were related to task changes. The number of infections in a country during the first wave of the pandemic was related to task changes. Other characteristics at country level were not associated with task changes. Future research on the sustainability of task changes after the pandemic is needed.

Patients' self-triage for unscheduled urgent care: a preliminary study on the accuracy and factors affecting the performance of a Belgian self-triage platform.

BACKGROUND: Management of unscheduled urgent care is a complex concern for many healthcare providers. Facing the challenge of appropriately dispatching unscheduled care, primary and emergency physicians have collaboratively implemented innovative strategies such as telephone triage. Currently, new original solutions tend to emerge with the development of new technologies. We created an interactive patient self-triage platform, ODISSEE, and aimed to explore its accuracy and potential factors affecting its performance using clinical case scenarios. METHODS: The ODISSEE platform was developed based on previously validated triage protocols for out-of-hours primary care. ODISSEE is composed of 18 icons leading to algorithmic questions that finally provide an advised orientation (emergency or primary care services). To investigate ODISSEE performance, we used 100 clinical case scenarios, each associated with a preestablished orientation determined by a group of experts. Fifteen volunteers were asked to self-triage with 50 randomly selected scenarios using ODISSEE on a digital tablet. Their triage results were compared with the experts' references. RESULTS: The 15 participants performed a total of 750 self-triages, which matched the experts references regarding the level of care in 85.6% of the cases. The orientation was incorrect in 14.4%, with an undertriage rate of 1.9% and an overtriage rate of 12.5%. The tool's specificity and sensitivity to advise participants on the appropriate level of care were 69% (95% CI: 64-74) and 97% (95% CI: 95-98) respectively. When combined with advice on the level of urgency, the tool only found the correct orientation in 68.4% with 9.2% of undertriages and 22.4% of overtriages. Some participant characteristics and the types of medical conditions demonstrated a significant association with the tool performance. CONCLUSION: Self-triage apps, such as the ODISSEE platform, could represent an innovative method to allow patients to self-triage to the most appropriate level of care. This study based on clinical vignettes highlights some positive arguments regarding ODISSEE safety, but further research is needed to assess the generalizability of such tools to the population without equity issues.

The Dynamic Relationship between the Intention and Final Decision for the COVID-19 Booster: A Study among Students and Staff at the University of Liège, Belgium.

While many studies have documented the intentions for the COVID-19 vaccine booster, few have explored the change from intention to final decision. This study explores the COVID-19 booster intentions and the change from intention to decision in a primo-vaccinated university population, with a distinction between staff members and students. It looks at the sociodemographic and medical characteristics, health literacy, personal COVID-19 infection and vaccination history, and attitudes/intentions regarding the booster, among the 1030 participants (64.4% staff members, 61.3% female, median age 36.0 years). Of the 8.7% who were initially hesitant, 72.7% ultimately got a booster and 27.3% did not. Another 84.2% intended to get a booster and 7.1% did not. Among the latter two groups, 88.9% maintained their intention and 11.1% changed their minds. The determinants associated with the intentions were health literacy and previous intentions regarding the COVID-19 primo-vaccination. The determinants associated with the change to non-vaccination were a previous COVID-19 infection, a past COVID-19 primo-vaccination intention, and a neutralizing antibody level. The results point to an opening for the support in decision-making, with a significant percentage of the study population potentially changing their mind between intention and final decision; this process should start early and be tailored to the individual's COVID-19 history. A personalized approach seems necessary in order to ensure that individuals make an informed choice.

Consensus on the Objectives of an Educational Intervention for Patients with Oropharyngeal Dysphagia and Their Informal Caregivers: A Delphi Study.

Purpose: In the absence of literature allowing for an evidence-based approach to therapeutic patient education (TPE) in Oropharyngeal Dysphagia (OD), this study aims to reach a consensus of experts on the content of a competency framework of an educational program for OD patients and their informal caregivers (ICGs). Methods: We used the Delphi consensus-building method. Four categories of experts were recruited: 12 patients, 17 ICGs, 46 healthcare professionals (HCP) (experienced in OD, not necessarily certified in TPE), and 19 experts in TPE (trained individuals to set up and run TPE programs not necessarily HCPs). The content of the questionnaire of the first round (R) was established according to the result of a scoping review and the opinion of an expert committee. We carried out three rounds. In R1 and R2, we collected the opinions on the relevance (7-point Likert-type scale) and on comprehensiveness (YES/No question and asking participants to propose additional content). Participants were also invited to leave comments on each objective. In R3, we asked the participants to give their opinion about the relevance of the objectives again and asked them to rank the themes from highest to lowest priority. Results: Objectives were considered relevant for all participants if they reached consensus when the interquartile (IQR) ≤ 1, and if the median indicated agreement (Mdn ≥ 6) (6= appropriate, 7 = totally appropriate). Following three rounds, the final content of the educational program is composed of 23 educational objectives organized in 13 themes with an agreement about relevance amongst all participants (Mdn ≥ 6; IQR ≤ 1). The comprehensiveness criterion received also a consensus (IQR ≤ 1). The participants ranked the theme "normal swallowing vs difficulty swallowing" as the highest priority. Conclusion: This Delphi study resulted in a consensus, on the content of a competency framework of an educational program for OD patients and their ICGs. Further steps are needed to construct learning activities based on these objectives before testing their feasibility and efficacy.

Factors influencing the adoption and participation rate of nursing homes staff in a saliva testing screening programme for COVID-19.

Testing strategies are crucial to prevent and control the spread of covid-19 but suffer from a lack of investment in understanding the human factors that influence their implementation. The aim of this study was to understand the factors that encourage participation and the level of engagement of nursing homes staff in a routine saliva testing programme for COVID-19 In December 2020, nursing homes (n = 571) in Wallonia (Belgium) were invited to participate in a saliva testing programme for their staff. The directors were questioned by telephone at the end of a 3-week pilot phase. 445 nursing homes took part in the evaluation questionnaire, of which 36(8%) answered that they chose not to participate in the testing programme. The average participation rate of nursing staff was 49(±25)%. Perception of the justification of the efforts required for testing and perception of practicability of the procedure were significantly associated with the adoption of the system by the nursing homes directors (OR(95%CI): 5.96(1.97-18.0), p = 0.0016); OR(95%CI): 5.64(1.94-16.4), p = 0.0015 respectively). Staff support, incentives and meetings increased the level of engagement in testing (p<0.05). While the adoption of the programme confirmed the acceptability of salivary testing as a means of screening, the participation rate confirmed the need for studies to understand the factors that encourage health care staff to take part. The results suggested rethinking strategies to consider staff engagement from a health promotion perspective.
