Introduction: Substance misuse significantly impairs psychosocial functioning and correlates with many environmental factors, including working conditions. We investigated the influence of working conditions and other determinants on the risk of substance misuse among healthcare residents of Lyon, France., Methods: We conducted an online survey among medicine, dentistry and pharmacy residents of Lyon from May 30, 2022, to July 15, 2022. Participants reported their age, sex, residency specialty, and living conditions and completed the French Job Content Questionnaire, the Alcohol Use Disorder Identification Test - consumption, and questions exploring their current tobacco, alcohol, and illicit drug use. We constructed directed acyclic graphs to model the effect of working conditions on substance misuse and used them to perform multivariable logistic regressions., Results: Among the 1,936 residents of the Lyon subdivision, 904 (46.7%) completed the survey. Among these, 54.0% exhibited alcohol misuse, 23.7% reported tobacco misuse, and 34.5% reported illicit drug misuse. Working more than 48 h per week was not associated with any substance misuse. Low social support at work predicted the use of illicit drugs (aOR: 1.49, 95% CI: [1.04; 2.13]). Compared with general medicine residents, psychiatric residents had greater odds of reporting tobacco misuse (aOR: 2.28, 95% CI: [1.14; 4.58]) and illicit drug misuse (aOR: 2.51, 95% CI: [1.33; 4.74]). Pediatric and pharmacy residents had lower odds of reporting alcohol misuse (aOR: 0.42, 95% CI: [0.21; 0.84] and OR: 0.53, 95% CI: [0.28; 0.98], respectively)., Conclusions: Social support at work significantly impacts the risk of substance misuse among healthcare residents, as do other factors, such as residents' health specialty. These findings contribute to the development of appropriate institutional policies and support programs to improve the well-being of healthcare residents., (© 2024 S. Karger AG, Basel.)

Identifying parameters influencing SARS-CoV-2 antibody dynamics post infection or vaccination is crucial for refining vaccination strategies. In a longitudinal analysis of 1340 samples from 375 healthcare workers, we characterized peak serological response and IgG half-life. Peak antibody titers post 2 vaccine doses were ∼ 20 times higher than natural infection; conversely, infected individuals had extended antibody half-life. Clinical and demographical factors such as BMI, age and smoking shaped peak response without affecting anti-RBD IgG half-life. A third mRNA vaccine dose increased peak antibody titers and prolonged half-life compared to the second dose. These findings underscore the diverse kinetics of SARS-CoV-2 antibody responses, which is influenced by immunization type/number and clinical factors., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Sophie Trouillet-Assant reports financial support was provided by Agence Nationale de Recherches sur le Sida et les Hépatites Virales.

Assess the changes in post-traumatic stress disorder (PTSD), burnout, anxiety, depression, jobstrain, and isostrain levels over time among healthcare workers in emergency departments (EDs) after successive outbreaks of COVID-19. A prospective, multicenter study was conducted in 3 EDs and an emergency medical service. Healthcare workers who participated in our previous study were invited to participate in a follow-up 16 and 18 months and completed the questionnaires to assess symptoms of PTSD, burnout, anxiety, depression, jobstrain, and isostrain. Among the 485 healthcare workers asked to participate, 211 (43.5%) completed the survey at inclusion (122 were followed up at 3 months) and 59 participate to the follow-up study. At 16 months, 10.9% of healthcare workers had symptoms of PTSD and 17.4% at 18 months. At inclusion, 33.5% and 11.7% of healthcare workers had symptoms of anxiety and depression, respectively. A decrease in anxiety between inclusion and 16 months (p = 0.02) and an increase between 16 and 18 months (p = 0.009) was observed. At inclusion, 40.8% of all healthcare workers had symptoms of burnout. There was an increase in symptoms of burnout between inclusion and 18 months (p = 0.006). At inclusion, 43.2% and 29.5% of healthcare workers were exposed to jobstrain and isostrain, respectively. Jobstrain were higher among paramedics and administrative staff compared to physicians (p = 0.001 and p = 0.026, respectively). Successive outbreaks of COVID-19 led to long-term mental health consequences among ED healthcare workers that differed according to occupation. This must be taken into account to rethink the management of teams., (© 2024 The Author(s). Stress and Health published by John Wiley & Sons Ltd.)

Background: Women with breast cancer face many barriers to return to work (RTW) after their cancer. The main objective of the FASTRACS-RCT is to evaluate the impact of the FASTRACS (Facilitate and Sustain Return to Work after Breast Cancer) intervention on the sustainable RTW of breast cancer patients, 12 months after the end of active treatment., Methods: FASTRACS-RCT is a prospective, national, multicentre, randomized, controlled and open-label study. A total of 420 patients with early breast cancer scheduled for surgery and (neo)adjuvant chemotherapy, will be randomly assigned (1:1 ratio) to: (i) the intervention arm comprising four steps over 6 months : Handing over the intervention tools; transitional medical consultation with the general practitioner (GP); pre-RTW visit with the company's occupational physician (OP); catch-up visit with a hospital-based RTW expert (if sick leave > 10 months) (ii) the control arm to receive usual care. The design of the FASTRACS intervention was informed by intervention mapping for complex interventions in health promotion planning, and involved patients and representatives of relevant stakeholders. Specific tools were developed to bridge the gap between the hospital, the GP, the OP and the workplace: a toolkit for breast cancer patients comprising a theory-based guide; specific checklists for the GP and the OP, respectively; and a theory-based guide for workplace actors (employer, manager, colleagues). The primary endpoint will associate sustainable RTW (full-time or part-time work at 50% or more of working time, for at least 28 consecutive days) and days off work. It will be assessed at 4, 8 and 12 months after the end of active oncological treatment. Secondary endpoints will include quality of life, anxiety, depression, RTW self-efficacy, physical activity, social support, job accommodations, work productivity, job status, and the usefulness and acceptability of the intervention's tools., Discussion: FASTRACS-RCT will be supplemented by a realist evaluation approach aimed at understanding the influence of context in activating the intervention's mechanisms and effects. If the expected impact of the intervention is confirmed, the intervention will be adapted and scaled-up for other cancers and chronic diseases to better integrate healthcare and work disability prevention., Trial Registration: NCT04846972 ; April 15, 2021., (© 2024.

Purpose: Return to work (RTW) is important for quality of life after breast cancer but its analysis at the population-level remains limited in France. This study aimed to implement Electronic Healthcare Data (EHD)-based indicators and trajectories to measure RTW after breast cancer diagnosis, and to examine stakeholders' perspectives regarding these indicators., Methods: We followed a mixed-methods approach that consisted of (i) implementing RTW indicators and identifying clusters of trajectories using state sequence analysis with data from a representative sample of the French National Health Data System and (ii) exploring, through qualitative focus group and interviews, stakeholders' perceptions on the interpretation, limitations, and utility of these indicators., Results: We extracted data from 317 women aged 25-55 years with a first diagnosis of early-stage breast cancer. The median number of sickness absence periods was 2 for a total of 434 days during the 3-year follow-up, and the median time to sustainable RTW was 240 days. Three clusters of RTW trajectories were identified: "early RTW" (49.5% of the population), "RTW after partial resumption" (37.5%) and "continuous compensation" (12.9%). Feedback from stakeholders highlighted the multi-factorial nature of RTW and underscored the added value of EHD for studying RTW, despite certain limitations., Conclusions: We demonstrated the feasibility of calculating RTW indicators and identifying trajectories using the French National Health Data System. These indicators can serve as outcome measures in RTW promotion and provide a basis for designing targeted interventions for breast cancer survivors., Competing Interests: Disclosure The authors have stated that they have no conflicts of interest., (Copyright © 2024 Elsevier Inc.

Objectives: In the post-SARS-CoV-2 pandemic era, "breakthrough infections" are still documented, due to variants of concerns (VoCs) emergence and waning humoral immunity. Despite widespread utilization, the definition of the anti-Spike (S) immunoglobulin-G (IgG) threshold to define protection has unveiled several limitations. Here, we explore the advantages of incorporating T-cell response assessment to enhance the definition of immune memory profile., Methods: SARS-CoV-2 interferon-gamma release assay test (IGRA) was performed on samples collected longitudinally from immunocompetent healthcare workers throughout their immunization by infection and/or vaccination, anti-receptor-binding domain IgG levels were assessed in parallel. The risk of symptomatic infection according to cellular/humoral immune capacities during Omicron BA.1 wave was then estimated., Results: Close to 40% of our samples were exclusively IGRA-positive, largely due to time elapsed since their last immunization. This suggests that individuals have sustained long-lasting cellular immunity, while they would have been classified as lacking protective immunity based solely on IgG threshold. Moreover, the Cox regression model highlighted that Omicron BA.1 circulation raises the risk of symptomatic infection while increased anti-receptor-binding domain IgG and IGRA levels tended to reduce it., Conclusion: The discrepancy between humoral and cellular responses highlights the significance of assessing the overall adaptive immune response. This integrated approach allows the identification of vulnerable subjects and can be of interest to guide antiviral prophylaxis at an individual level., (© 2024 The Authors.

Introduction: The mental health of residents is a growing significant concern, particularly with respect to hospital and university training conditions. Our goal was to assess the professional, academic, and psychological determinants of the mental health status of all residents of the academy of Lyon, France., Materials and Methods: The Health Barometer of Lyon Subdivision Residents (BASIL) is an initiative which consists in proposing a recurrent online survey to all residents in medicine, pharmacy, and dentistry, belonging to the Lyon subdivision. The first of these surveys was conducted from May to July 2022. Participants should complete a series of validated questionnaires, including the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), and the Kessler Psychological Distress Scale (K6), respectively, and ad-hoc questions assessing their global health and hospital and academic working conditions. A Directed Acyclic Graph (DAG) analysis was conducted prior to multivariable analyses, to explore the determinants associated with low wellbeing (WEMWBS <43) and high psychological distress (K6 ≥ 13)., Results: A total of 904 residents (response rate: 46.7%) participated in the survey. A low level of wellbeing was observed in 23% of participants, and was significantly associated to job strain (OR = 2.18; 95%CI = [1.32-3.60]), low social support (OR = 3.13; 95%CI = [2.05-4.78]) and the experience of very poor university teaching (OR = 2.51; 95%CI = [1.29-4.91]). A high level of psychological distress was identified for 13% of participants, and associated with low social support (OR = 2.41; 95%CI = [1.48-3.93]) and the experience of very poor university teaching (OR = 2.89, 95%CI = [1.16-7.21])., Conclusion: Hospital working conditions, social support, and the perception of teaching quality, were three major determinants of wellbeing and psychological distress among health profession residents. Demographic determinants, personal life and lifestyle habits were also associated. This supports a multilevel action in prevention programs aiming to enhance wellbeing and reduce mental distress in this specific population and local organizational specificities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Nohales, Fort, Pelloux, Coste, Leblanc, De Ternay, Wallon, Rolland, Fassier and BASIL Study Group.)

Addressing health challenges that impact human well-being requires a comprehensive, interdisciplinary approach that would be at the crossroad of population-based prevention and individual-level clinical care, which is in line with a Global Health perspective. In the absence of a unifying theoretical framework to guide such interventions, a Dynamic Ecosystem Adaptation through the Allostasis (DEA-A) framework has been proposed, emphasizing the functional adaptation of individuals and organizations in symbiosis with their living ecosystem. While a conceptual model has been presented, this methodological contribution aims at illustrating the practical application of the DEA-A framework for planning Global Health interventions. The methodology combines Intervention Mapping and Cognitive and Behavioral Theory, extended to the ecosystem. Practical guidelines and supporting tools are provided to help public health providers and clinicians in establishing a functional ecosystem diagnosis of the issue; defining not only behavioral, but also emotional and cognitive change objectives (allostasis targets) expected for each stakeholder; and designing intervention plans targeting determinants of these allostasis. The discussion addresses implementation and evaluation perspectives of interventions based on the DEA-A framework, emphasizing the importance of considering change in its processual and ecosystem complexity. Lastly, encouragements for a deeper understanding of individual and ecosystem homeostasis/allostasis processes are made in order to promote more functional interventions.

Background: Regional Centers for Occupational and Environmental Pathologies (CRPPE) are responsible for identifying possible occupational etiologies of pathologies. When an occupational origin is determined, an Initial Medical Certificate (IMC) is given to the patient to allow him to initiate a procedure for recognition as an occupational disease (OD) by his health insurance organization., Objectives: The main aim of this study was to investigate the outcome of occupational disease claims in patients who received an IMC delivered by the CRPPE of Lyon., Methods: A telephone interview was systematically conducted with patients who consulted the CRPPE for a claim for occupational disease recognition between 07/2020 and 06/2021, about six months after the consultation. It was conducted by a physician using a standardized questionnaire., Results: Out of 128 patients eligible for this study, 98 were included. Diseases of the respiratory system (34.7%) and cancers (28.6%) were the most common pathologies in our population. A process of OD compensation was initiated by 86 patients (87.8%). At the time of the study, the outcome was favorable for 63 patients (73.3%). Moreover, 18 patients (18.4%) wished for additional help from the CRPPE to carry out the procedures. Nine patients requested a new consultation, including five who still needed to complete the process., Conclusion: This study shows the benefit of a consultation by occupational disease consultants. However, difficulties still need to be solved in these procedures. Thus, the systematic follow-up of patients shows its advantages. The provision of support to carry out the process seems necessary.

BackgroundTo cope with the persistence of the COVID-19 epidemic and the decrease in antibody levels following vaccination, a third dose of vaccine has been recommended in the general population. However, several vaccine regimens had been used initially for the primary vaccination course, and the heterologous Vaxzevria/Comirnaty regimen had shown better efficacy and immunogenicity than the homologous Comirnaty/Comirnaty regimen.AimWe wanted to determine if this benefit was retained after a third dose of an mRNA vaccine.MethodsWe combined an observational epidemiological study of SARS-CoV-2 infections among vaccinated healthcare workers at the University Hospital of Lyon, France, with a prospective cohort study to analyse immunological parameters before and after the third mRNA vaccine dose.ResultsFollowing the second vaccine dose, heterologous vaccination regimens were more protective against infection than homologous regimens (adjusted hazard ratio (HR) = 1.88; 95% confidence interval (CI): 1.18-3.00; p = 0.008), but this was no longer the case after the third dose (adjusted HR = 0.86; 95% CI: 0.72-1.02; p = 0.082). Receptor-binding domain-specific IgG levels and serum neutralisation capacity against different SARS-CoV-2 variants were higher after the third dose than after the second dose in the homologous regimen group, but not in the heterologous group.ConclusionThe advantage conferred by heterologous vaccination was lost after the third dose in terms of both protection and immunogenicity. Immunological measurements 1 month after vaccination suggest that heterologous vaccination induces maximal immunity after the second dose, whereas the third dose is required to reach the same level in individuals with a homologous regimen.

The diversity of vaccination modalities and infection history are both variables that have an impact on the immune memory of individuals vaccinated against SARS-CoV-2. To gain more accurate knowledge of how these parameters imprint on immune memory, we conducted a long-term follow-up of SARS-CoV-2 spike protein-specific immune memory in unvaccinated and vaccinated COVID-19 convalescent individuals as well as in infection-naïve vaccinated individuals. Here, we report that individuals from the convalescent vaccinated (hybrid immunity) group have the highest concentrations of spike protein-specific antibodies at 6 months after vaccination. As compared with infection-naïve vaccinated individuals, they also display increased frequencies of an atypical mucosa-targeted memory B cell subset. These individuals also exhibited enhanced T H 1 polarization of their SARS-CoV-2 spike protein-specific follicular T helper cell pool. Together, our data suggest that prior SARS-CoV-2 infection increases the titers of SARS-CoV-2 spike protein-specific antibody responses elicited by subsequent vaccination and induces modifications in the composition of the spike protein-specific memory B cell pool that are compatible with enhanced functional protection at mucosal sites.

In the context of the COVID-19 pandemic, this commentary describes and compares shifting employment and occupational health social protections of low-wage workers, including self-employed digital platform workers. Through a focus on eight advanced economy countries, this paper identifies how employment misclassification and definitions of employees were handled in law and policy. Debates about minimum wage and occupational health and safety standards as they relate to worker well-being are considered. Finally, we discuss promising changes introduced during the COVID-19 pandemic that protect the health of low-wage and self-employed workers. Overall, we describe an ongoing "haves" and a "have not" divide, with on the one extreme, traditional job arrangements with good work-and-health social protections and, on the other extreme, low-wage and self-employed digital platform workers who are mostly left out of schemes. However, during the pandemic small and often temporary gains occurred and are discussed.

A total of 92 coronavirus disease 2019 clusters involving 1,156 individuals (729 patients and 427 healthcare workers) occurred in Lyon University Hospital between September 1, 2020 and March 31, 2021, mostly on medical and geriatric wards. The number of clusters was closely correlated to the trend in coronavirus disease 2019 community incidence over time; in-hospital clusters did not persist when community incidence decreased. Recommended preventive measures were not fully applicable due to specific ward-associated determinants and patient characteristics., (Copyright © 2022 Association for Professionals in Infection Control and Epidemiology, Inc.

The virus neutralization test (VNT) is the reference for the assessment of the functional ability of neutralizing antibodies (NAb) to block SARS-CoV-2 entry into cells. New competitive immunoassays measuring antibodies preventing interaction between the spike protein and its cellular receptor are proposed as surrogate VNT (sVNT). We tested three commercial sVNT (a qualitative immunochromatographic test and two quantitative immunoassays named YHLO and TECO) together with a conventional anti-spike IgG assay (bioMérieux) in comparison with an in-house plaque reduction neutralization test (PRNT 50 ) using the original 19A strain and different variants of concern (VOC), on a panel of 306 sera from naturally-infected or vaccinated patients. The qualitative test was rapidly discarded because of poor sensitivity and specificity. Areas under the curve of YHLO and TECO assays were, respectively, 85.83 and 84.07 (p-value >0.05) using a positivity threshold of 20 for PRNT 50 , and 95.63 and 90.35 (p-value =0.02) using a threshold of 80. However, the performances of YHLO and bioMérieux were very close for both thresholds, demonstrating the absence of added value of sVNT compared to a conventional assay for the evaluation of the presence of NAb in seropositive subjects. In addition, the PRNT 50 assay showed a reduction of NAb titers towards different VOC in comparison to the 19A strain that could not be appreciated by the commercial tests. Despite the good correlation between the anti-spike antibody titer and the titer of NAb by PRNT 50 , our results highlight the difficulty to distinguish true NAb among the anti-RBD antibodies with commercial user-friendly immunoassays., (Copyright © 2022.

Introduction: The self-efficacy to return to work is a major psychological factor of the return to work of patients diagnosed with a cancer. However, french investigations in this field do not take this dimension into account due to the lack of a suitable tool for its assessment. The objective of this study was to provide a french translation and adaptation of the "Return to Work Self-Efficacy' scale - 11 items" (RTWSE-11), validated in dutch language in its original version., Methods: After translation-back translation steps, completed by experts' consensus meetings, interviews were conducted with thirteen patients diagnosed with cancer in order to evaluate the degree of clarity, simplicity and ambiguity or the various elements of the french version of the RTW-SE-11., Results: The main modifications inherent to the french adaptation of the questionnaire concerned the modalities of the Likert scale and the inversion of three negative items into positive items., Discussion: The french translation and adaptation of the RTWSE-11 was particularly faithful to the semantic, idiomatic, functional, experiential, conceptual and operational aspects of the original version. Future work can therefore focus on the psychometrics evaluations of the questionnaire. However, this tool can already be used in clinical practice to establish an initial assessment of the ability of patients diagnosed with cancer to return to work., (Copyright © 2021 Société Française du Cancer.

With the availability of vaccines, commercial assays detecting anti-severe acute respiratory syndrome coronavirus-2 antibodies (Ab) evolved toward quantitative assays directed to the spike glycoprotein or its receptor binding domain (RBD). The main objective of the present study was to compare the Ab titers obtained with quantitative commercial binding Ab assays, after one dose (convalescent individuals) or two doses (naive individuals) of vaccine, in health care workers (HCW). Antibody titers were measured in 255 sera (from 150 HCW) with five quantitative immunoassays (Abbott RBD IgG II quant, bioMérieux RBD IgG, DiaSorin Trimeric spike IgG, Siemens Healthineers RBD IgG, Wantai RBD IgG). One qualitative total antibody anti-RBD detection assay (Wantai) was used to detect previous infection before vaccination. The results are presented in binding Ab units (BAU)/mL after application, when possible, of a conversion factor provided by the manufacturers and established from a World Health Organization internal standard. There was a 100% seroconversion with all assays evaluated after two doses of vaccine. With assays allowing BAU/mL correction, Ab titers were correlated (Pearson correlation coefficient, ρ, range: 0.85-0.94). The titer differences varied by a mean of 10.6% between Siemens and bioMérieux assays to 60.9% between Abbott and DiaSorin assays. These results underline the importance of BAU conversion for the comparison of Ab titer obtained with the different quantitative assays. However, significant differences persist, notably, between kits detecting Ab against the different antigens. A true standardization of the assays would be to include the International Standard in the calibration of each assay to express the results in IU/mL.

Background: Occupational blood and body fluid exposures (OBBFEs) are one of the biological risks run by health professionals, especially in hospitals., Objective: The objectives of this study were to assess the occurrence and reporting of occupational blood and body fluid exposures (OBBFEs) in university hospital medical staff and to investigate factors associated to declared OBBFE and factors associated to reported OBBFE., Methods: A self-administered questionnaire has been e-mailed to all junior and senior medical staff in four university hospital centers in one administrative region of France in 2017., Results: 292 of the 1,228 respondents declared at least one OBBFE. More than two-thirds (70.2%) were under-reporters and more than half (53.8%) non-reporters. Younger subjects, surgical specialties and other associated work accidents were risk factors for OBBFE. Considering the reporting procedure too complex was a risk factor for underreporting., Conclusions: Underreporting by hospital medical staff was a persistent phenomenon, with a high rate. The OBBFE reporting procedure needs rethinking.

Objective: To develop guidelines for low back pain management according to previous international guidelines and the updated literature., Methods: A report was compiled from a review of systematic reviews of guidelines published between 2013 and 2018 and meta-analysis of the management of low back pain published between 2015 and 2018. This report summarized the state-of-the-art scientific knowledge for each predefined area of the guidelines from a critical review of selected literature. A multidisciplinary panel of experts including 17 health professionals involved in low back pain management and 2 patient representatives formulated preliminary guidelines based on the compilation report and a care pathway. The compilation report and preliminary guidelines were submitted to 25 academic institutions and stakeholders for the consultation phase. From responses of academic institutions and stakeholders, the final guidelines were developed. For each area of the guidelines, agreement between experts was assessed by the RAND/UCLA method., Results: The expert panel drafted 32 preliminary recommendations including a care pathway, which was amended after academic institution and stakeholder consultation. The consensus of the multidisciplinary expert panel was assessed for each final guideline: 32 recommendations were assessed as appropriate; none was assessed as uncertain or inappropriate. Strong approval was obtained for 27 recommendations and weak for 5., Conclusion: These new guidelines introduce several concepts, including the need to early identify low back pain at risk of chronicity to provide quicker intensive and multidisciplinary management if necessary., (Copyright © 2021.

Following severe adverse reactions to the AstraZeneca ChAdOx1-S-nCoV-19 vaccine 1,2 , European health authorities recommended that patients under the age of 55 years who received one dose of ChAdOx1-S-nCoV-19 receive a second dose of the Pfizer BNT162b2 vaccine as a booster. However, the effectiveness and the immunogenicity of this vaccination regimen have not been formally tested. Here we show that the heterologous ChAdOx1-S-nCoV-19 and BNT162b2 combination confers better protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than the homologous BNT162b2 and BNT162b2 combination in a real-world observational study of healthcare workers (n = 13,121). To understand the underlying mechanism, we conducted a longitudinal survey of the anti-spike immunity conferred by each vaccine combination. Both combinations induced strong anti-spike antibody responses, but sera from heterologous vaccinated individuals displayed a stronger neutralizing activity regardless of the SARS-CoV-2 variant. This enhanced neutralizing potential correlated with increased frequencies of switched and activated memory B cells that recognize the SARS-CoV-2 receptor binding domain. The ChAdOx1-S-nCoV-19 vaccine induced a weaker IgG response but a stronger T cell response than the BNT162b2 vaccine after the priming dose, which could explain the complementarity of both vaccines when used in combination. The heterologous vaccination regimen could therefore be particularly suitable for immunocompromised individuals., (© 2021. The Author(s), under exclusive licence to Springer Nature Limited.)

IFN-I and IFN-III immunity in the nasal mucosa is poorly characterized during SARS-CoV-2 infection. We analyze the nasal IFN-I/III signature, namely the expression of ISGF-3-dependent IFN-stimulated genes, in mildly symptomatic COVID-19 patients and show its correlation with serum IFN-α2 levels, which peak at symptom onset and return to baseline from day 10 onward. Moreover, the nasal IFN-I/III signature correlates with the nasopharyngeal viral load and is associated with the presence of infectious viruses. By contrast, we observe low nasal IFN-I/III scores despite high nasal viral loads in a subset of critically ill COVID-19 patients, which correlates with the presence of autoantibodies (auto-Abs) against IFN-I in both blood and nasopharyngeal mucosa. In addition, functional assays in a reconstituted human airway epithelium model of SARS-CoV-2 infection confirm the role of such auto-Abs in abrogating the antiviral effects of IFN-I, but not those of IFN-III. Thus, IFN-I auto-Abs may compromise not only systemic but also local antiviral IFN-I immunity at the early stages of SARS-CoV-2 infection., Competing Interests: Disclosures: M. Mommert, W. Mouton, K.

Introduction: Despite safety and benefits of physical activity during treatment of localised breast cancer, successful exercise strategies remain to be determined. The primary objective of the 'dispositif connecté', that is, connected device in English trial is to evaluate the efficacy of two 6-month exercise interventions, either single or combined, concomitant to adjuvant treatments, on the physical activity level of patients with breast cancer, compared with usual care: an exercise programme using a connected device (activity tracker, smartphone application, website) and a therapeutic patient education intervention. Secondary objectives are to evaluate adherence to interventions, their impact at 6 and 12 months, representations and acceptability of interventions, and to assess the cost-effectiveness of the interventions using quality-adjusted life-years., Methods and Analysis: This is a 2×2 factorial, multicentre, phase III randomised controlled trial. The study population (with written informed consent) will consist of 432 women diagnosed with primary localised invasive breast carcinoma and eligible for adjuvant chemotherapy, hormonotherapy and/or radiotherapy. They will be randomly allocated between one of four arms: (1) web-based connected device (evolving target number of daily steps and an individualised, semisupervised, adaptive programme of two walking and one muscle strengthening sessions per week in autonomy), (2) therapeutic patient education (one educational diagnosis, two collective educational sessions, one evaluation), (3) combination of both interventions and (4) control. All participants will receive the international physical activity recommendations. Assessments (baseline, 6 and 12 months) will include physical fitness tests, anthropometrics measures, body composition (CT scan, bioelectrical impedance), self-administered questionnaires (physical activity profile (Recent Physical Activity Questionnaire), quality of life (European Organization for Research and Treatment of Cancer Quality-Of-Life Questionnaire-30, EQ-5D-5L), fatigue (Piper Fatigue Scale-12), social deprivation (Evaluation of Deprivation and Inequalities in Health Examination Centres), lifestyle, physical activity barriers, occupational status) and biological parameters (blood draw)., Ethics and Dissemination: This study was reviewed and approved by the French Ethics Committee. The findings will be disseminated to the scientific and medical community via publications in peer-reviewed journals and conference presentations., Trial Registration Number: NCT03529383; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

The worldwide global increase in serum 25-hydroxyvitamin D (25(OH)D) measurements has led some countries to restrict reimbursement for certain clinical situations only. Another approach could consist in providing physicians with screening tools in order to better target blood test prescription. The objective of the SCOPYD study was to identify the best combination of predictors of serum VitD concentration among adults aged 18-70 years. Potential risk factors for VitD deficiency were collected using a comprehensive self-administered questionnaire. A multivariable linear regression was used to build a predictive model of serum 25(OH)D concentration. Among 2488 participants, 1080 (43.4%) had VitD deficiency (<50 nmol/L) and 195 (7.8%) had severe deficiency (<25 nmol/L). The final model included sunlight exposure in the preceding week and during the last holidays, month of blood sampling, age, sex, body mass index, skin phototype, employment, smoking, sport practice, latitude, and VitD supplementation in preceding year. The area under the curve was 0.82 (95% CI (0.78; 0.85)) for severe deficiency. The model predicted severe deficiency with a sensitivity of 77.9% (95% CI (69.1; 85.7)) and a specificity of 68.3% (95% CI (64.8; 71.9)). We identified a set of predictors of severe VitD deficiency that are easy to collect in routine that may help to better target patients for serum 25(OH)D concentration determination.

A comprehensive clinical and microbiological assessments of COVID-19 in front-line healthcare workers (HCWs) is needed. Between April 10th and May 28th, 2020, 319 HCWs with acute illness were reviewed. In addition to SARS-CoV-2 RT-PCR screening, a multiplex molecular panel was used for testing other respiratory pathogens. For SARS-CoV-2 positive HCWs, the normalized viral load, viral culture, and virus neutralization assays were performed weekly. For SARS-CoV-2 negative HCWs, SARS-CoV-2 serological testing was performed one month after inclusion. Among the 319 HCWs included, 67 (21.0%) were tested positive for SARS-CoV-2; 65/67 (97.0%) developed mild form of COVID-19. Other respiratory pathogens were found in 6/66 (9.1%) SARS-CoV-2 positive and 47/241 (19.5%) SARS-Cov-2 negative HCWs (p = 0.07). The proportion of HCWs with a viral load > 5.0 log 10  cp/mL (Ct value < 25) was less than 15% at 8 days after symptom onset; 12% of HCWs were positive after 40 days (Ct > 37). More than 90% of cultivable virus had a viral load > 4.5 log 10  cp/mL (Ct < 26) and were collected within 10 days after symptom onset. Among negative HCWs, 6/190 (3.2%) seroconverted. Our data suggest that the determination of viral load can be used for appreciating the infectiousness of infected HCWs. These data could be helpful for facilitating their return to work., (© 2021.

Introduction: Smoking prevalence in the overall population in France was 27% in 2017. There are few data about smoking prevalence in hospital workers. The aim of this study was to assess prevalence of current smoking in student and staff populations at Lyon University Hospital. Secondary objectives were to identify main variables associated with current smoking and willingness to quit., Methods: We designed a single center, cross-sectional survey, using printed questionnaires. During one day, all registered staff and students were surveyed. We used optical reading to extract information from questionnaires. We performed univariate and multivariate analysis adjusted on most relevant factors., Results: We analyzed 9712 questionnaires. The participating rates were high: 40.6% in the student cohort and 51.5% in the staff cohort. The proportion of current cigarette users was 26% in students and 25% in staff. In multivariate analysis, current smoking was significantly associated with: younger age, male sex, occupation type (e.g. logistical staff, and paramedical students), overnight work, and e-cigarette use. Among smokers, 53% reported a willingness to quit. In multivariate analysis, number of quit attempts, and feeling symptoms from tobacco were associated with willingness to quit., Conclusions: Current smoking is less frequent in our cohorts of hospital staff and students than in the general French population. However, there are deep disparities in current smoking prevalence underlining a heterogeneous population. Among smokers, the majority reported a willingness to quit and some predictive factors may help to target this audience., Competing Interests: The authors have each completed and submitted an ICMJE form for disclosure of potential conflicts of interest.

Background: The association between SARS-CoV-2 commercial serological assays and virus neutralization test (VNT) has been poorly explored in mild patients with COVID-19., Methods: 439 serum specimens were longitudinally collected from 76 healthcare workers with RT-PCR-confirmed COVID-19. The clinical sensitivity (determined weekly) of 9 commercial serological assays were evaluated. Clinical specificity was assessed using 69 pre-pandemic sera. Correlation, agreement, and concordance with the VNT were also assessed on a subset of 170 samples. Area under the ROC curve (AUC) was estimated at 2 neutralizing antibody titers., Results: The Wantai Total Ab assay targeting the receptor binding domain (RBD) within the S protein presented the best sensitivity at different times during the course of disease. The clinical specificity was greater than 95% for all tests except for the Euroimmun IgA assay. The overall agreement with the presence of neutralizing antibodies ranged from 62.2% (95%CI; 56.0-68.1) for bioMérieux IgM to 91.2% (87.0-94.2) for Siemens. The lowest negative percent agreement (NPA) was found with the Wantai Total Ab assay (NPA 33% (21.1-48.3)). The NPA for other total Ab or IgG assays targeting the S or the RBD was 80.7% (66.7-89.7), 90.3% (78.1-96.1), and 96.8% (86.8-99.3) for Siemens, bioMérieux IgG, and DiaSorin, respectively. None of the commercial assays have sufficient performance to detect a neutralizing titer of 80 (AUC < 0.76)., Conclusions: Although some assays show a better agreement with VNT than others, the present findings emphasize that commercialized serological tests, including those targeting the RBD, cannot substitute a VNT for the assessment of functional antibody response., (© American Association for Clinical Chemistry 2021.

Low concentrations of type-I interferon (IFN) in blood seem to be associated with more severe forms of Coronavirus disease 2019 (COVID-19). However, following the type-I interferon response (IR) in early stage disease is a major challenge. We evaluated detection of a molecular interferon signature on a FilmArray® system, which includes PCR assays for four interferon stimulated genes. We analyzed three types of patient populations: (i) children admitted to a pediatric emergency unit for fever and suspected infection, (ii) ICU-admitted patients with severe COVID-19, and (iii) healthcare workers with mild COVID-19. The results were compared to the reference tools, that is, molecular signature assessed with Nanostring® and IFN-α2 quantification by SIMOA® (Single MOlecule Array). A strong correlation was observed between the IR measured by the FilmArray®, Nanostring®, and SIMOA® platforms (r-Spearman 0.996 and 0.838, respectively). The FilmArray® panel could be used in the COVID-19 pandemic to evaluate the IR in 45-min with 2 min hand-on-time at hospitalization and to monitor the IR in future clinical trials., (© 2021 The Authors.

Introduction: The COVID-19 pandemic caused by SARS-CoV-2 threatens global public health, and there is an urgent public health need to assess acquired immunity to SARS-CoV-2. Serological tests might provide results that can be complementary to or confirm suspected COVID-19 cases and reveal previous infection. The performance of serological assays (sensitivity and specificity) has to be evaluated before their use in the general population. The neutralisation capacity of the produced antibodies also has to be evaluated., Methods and Analysis: We set up a prospective, multicentric clinical study to evaluate the performance of serological kits among a population of healthcare workers presenting mild symptoms suggestive of SARS-CoV-2 infection. Four hundred symptomatic healthcare workers will be included in the COVID-SER study. The values obtained from a control cohort included during the prepandemic time will be used as reference. A workflow was set up to study serological response to SARS-CoV-2 infection and to evaluate antibody neutralisation capacity in patients with a confirmed SARS-CoV-2 infection. The sensitivity and specificity of the tests will be assessed using molecular detection of the virus as a reference. The measurement of IgM and IgG antibodies will be performed once per week for 6 consecutive weeks and then at 6, 12, 18, 24 and 36 months after the diagnosis. The kinetics of IgM and IgG will determine the optimal period to perform serological testing. The proportion of false negative PCR tests in symptomatic subjects will be determined on the basis of subsequent seroconversions., Ethics and Dissemination: Ethical approval has been obtained from the national review board for biomedical research in April 2020 (Comité de Protection des Personnes Sud Méditerranée I, Marseille, France) (ID RCB 2020-A00932-37). Results will be disseminated through presentations at scientific meetings and publications in peer-reviewed journals., Trial Registration Number: NCT04341142., Competing Interests: Competing interests: AB has received grant from bioMérieux and has served as consultant for bioMérieux for work and research not related to this manuscript., (© Author(s) (or their employer(s)) 2020.

This longitudinal study aimed at exploring the direct and indirect relationships between organizational, psychosocial, biomechanical, and personal factors and carpal tunnel syndrome (CTS) in French workers. Between 2002 and 2005, 3710 workers were included in the Cosali cohort. Between 2007 and 2010, 1611 workers were re-examined using the same standardized clinical protocol. Subjects free from CTS at baseline were studied (804 men and 563 women). We used structural equation models to examine the relationships between incident CTS cases and organizational (machine-paced work or work pace dependent on customers' demand), psychosocial (job strain model), biomechanical (Borg's rating perceived exertion, wrist bending, pinching, and hand-transmitted vibrations), and personal factors at baseline. Symptomatic CTS risk was directly increased by biomechanical factors (standardized coefficient = 0.19, P = 0.011), female gender (0.25, P < 0.001), and age (0.15, P = 0.042). No psychosocial factors had a direct impact on CTS, but decision authority and skill discretion had an indirect impact by influencing biomechanical exposure. Exposure to machine-paced work had an indirect impact on increasing CTS, either by raising biomechanical exposure (0.19, P < 0.001) or by lowering decision authority (-0.18, P < 0.001) and skill discretion (-0.20, P < 0.001), which in turn increased biomechanical exposure. Similar complex relationships were observed between risk factors and CTS defined by a more strict case definition. Biomechanical exposure had a direct impact on CTS, while organizational factors and psychosocial factors had an indirect impact on CTS. The findings support conceptual models linking work organization to CTS.

Objectives This study aimed to explore the views of breast cancer (BC) specialists as to their role in the return-to-work (RTW) process of their BC patients. Methods A qualitative study using semi-structured interviews was conducted in a sample of 20 BC specialists selected according to age, gender, medical specialty (medical oncology, radiation oncology, gynecological surgery), and healthcare organization (regional cancer center, university or private hospital). All interviews were audiotaped and transcribed for qualitative thematic content analysis. Results BC specialists had heterogeneous representations and practices regarding their role in their patients` RTW process, ranging from non-involvement to frequent discussion. Most BC specialists had concerns regarding the "right time and right way" to address patient`s RTW. They hardly mentioned workplace and job factors as potential barriers but rather stressed motivation. The main reported barriers to involvement in the RTW process were lack of time, lack of knowledge, lack of skills, and a professional attitude exclusively focused on cancer care issues. Conclusion While our study showed varying representations and practices among BC specialists, participants consistently identified barriers in supporting BC survivors` RTW. The results will guide the development of an intervention to facilitate the role of BC specialists in the RTW process as part of a multicomponent intervention to facilitate BC survivors` RTW.

Return to work is a public health priority which led the French Health Authority to publish recommendations about "return to work and health: prevention of exclusion from work". The aim of this article is to present a literature review of return to work after cancer. Studies about medium-term and long-term effects of cancer are sparse. They suggest worker durable effects. Factors associated with return to work are linked to the patient characteristics, to characteristics of the illness and the treatment, to the workplace and to the help provided to the patient during the return to work process. A specific plan for returning to work in 3 phases (situation comprehension, identification of negative and positive factors for returning to work, implementation of measures concerning the patient, the workplace and the coordination between return to work actors) should be built for each patient, involving the worker, the occupational practitioner, the general and specialist practitioners., (Copyright © 2019 Société Française du Cancer.

Objective and Setting: Primary prevention, comprising patient-oriented and environmental interventions, is considered to be one of the best ways to reduce violence in the emergency department (ED). We assessed the impact of a comprehensive prevention programme aimed at preventing incivility and verbal violence against healthcare professionals working in the ophthalmology ED (OED) of a university hospital., Intervention: The programme was designed to address long waiting times and lack of information. It combined a computerised triage algorithm linked to a waiting room patient call system, signage to assist patients to navigate in the OED, educational messages broadcast in the waiting room, presence of a mediator and video surveillance., Participants: All patients admitted to the OED and those accompanying them., Design: Single-centre prospective interrupted time-series study conducted over 18 months., Primary Outcome: Violent acts self-reported by healthcare workers committed by patients or those accompanying them against healthcare workers., Secondary Outcomes: Waiting time and length of stay., Results: There were a total of 22 107 admissions, including 272 (1.4%) with at least one act of violence reported by the healthcare workers. Almost all acts of violence were incivility or verbal harassment. The rate of violence significantly decreased from the pre-intervention to the intervention period (24.8, 95% CI 20.0 to 29.5, to 9.5, 95% CI 8.0 to 10.9, acts per 1000 admissions, p<0.001). An immediate 53% decrease in the violence rate (incidence rate ratio=0.47, 95% CI 0.27 to 0.82, p=0.0121) was observed in the first month of the intervention period, after implementation of the triage algorithm., Conclusion: A comprehensive prevention programme targeting patients and environment can reduce self-reported incivility and verbal violence against healthcare workers in an OED., Trial Registration Number: NCT02015884., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Objectives: Thirty percent of the general population are Staphylococcus aureus nasal carriers. It has been shown that this increases with repeated contact with patients, but it is not known whether all categories of healthcare workers are at equal risk of carriage. We aimed to explore S. aureus nasal carriage among healthcare professionals., Methods: Prospective study conducted in two French university hospitals in 2014 and 2016. Volunteers were screened for S. aureus nasal carriage. Profession and hygiene habits were collected. Based on the results of this initial study, a second study focused on semi-skilled workers and biomedical equipment technicians (BETs) only; participants were given education on the basic rules of hygiene, then re-screened three months later., Results: In the initial study, 38.8% of the 436 participants were detected as nasal carriers. There was a significant difference in nasal carriage according to professional category (p < 0.0001); the lowest was found among administrative agents (17.3%), followed by healthcare providers (37.4%), laboratory technicians (37.6%). The greatest proportion was found among semi-skilled workers and BETs (52.9%). Spa-typing ruled out the hypothesis of a single clone dissemination among colleagues. After the three-month hygiene awareness campaign, all re-screened individuals remained positive, and with their respective initial strain., Conclusions: To the best of our knowledge we report here for the first time that semi-skilled workers and BETs are specifically more at risk of S. aureus nasal colonisation. This striking finding urges hospital hygiene departments to evaluate this specific professional category and implement strategies to improve hygiene awareness., (Copyright © 2019 Elsevier GmbH.

Purposes Intervention mapping (IM) is a protocol for developing effective behavior change interventions. It has been used for 10 years to develop work disability prevention (WDP) interventions, but it is not known to what extent and with what success. The main objective of this study was to review the effectiveness of these interventions. Secondary objectives were to review their fidelity to the IM protocol, their theoretical frameworks and their content. Methods A search strategy was conducted in MEDLINE, Web of Science, PsycINFO, Pascal, Francis, and BDSP. All titles and abstracts were reviewed. A standardized extraction form was developed. All included studies were reviewed by two reviewers blinded to each other. Results Eight WDP interventions were identified aimed at return to work (RTW; n = 6) and self-management at work (n = 2). RTW interventions targeted workers with stress-related mental disorders (n = 1), low back pain (n = 1), musculoskeletal disorders (n = 1), cancer (n = 2) and gynecological surgery (n = 1). The fidelity to the IM protocol was weaker for the participatory planning group. Matrices of change, change methods, and applications were systematically reported. The main theoretical frameworks used were the attitude-social influence-self efficacy model (n = 4) and the theory of planned behavior (n = 2). Half of the interventions included a workplace component (n = 4). Two interventions were reported as effective, and one partially effective. Conclusion The IM protocol is used in WDP since 2007. The participative dimension appears underused. Few theoretical frameworks were used. Implications are to better consider the stakeholders involvement, and mobilize theoretical frameworks with greater attempts to intervene on the work environment.

This study aimed to evaluate the association between intention to leave work, and working conditions and health status among female care-staff in nursing homes. A multicenter cross-sectional study included female care-staff in 105 nursing homes for the elderly. We used validated questionnaires to assess occupational, psychosocial and medical data in a multicenter transverse study. Univariate analysis on chi² test was performed with stratification according to job (nurse, nursing assistant), and variables found to be significant on each dimension were included on multivariate models. 1428 nursing assistants and 342 registered nurses were included. 391 nursing assistants and 85 registered nurses intended to leave their work with the elderly. The registered nurses' intention to leave was associated with deteriorated care-team or residents relations, and with perceived elevated hardship due to the proximity of residents' death. The nursing assistants' intention to leave was associated with deteriorated management relation, with job insecurity and elevated hardship due to the residents' intellectual deterioration. Impaired physical or psychological health status also correlated with this intention. Policy to reduce voluntary turnover of care-staff in nursing homes for the elderly could be based on multifactorial management, acting on work organization and reducing psychosocial stress.

Objectives: The Intervention Mapping (IM) protocol provides a structured framework to develop, implement, and evaluate complex interventions. The main objective of this review was to identify and describe the content of the interventions developed in the field of cancer with the IM protocol. Secondary objectives were to assess their fidelity to the IM protocol and to review their theoretical frameworks., Methods: Medline, Web of Science, PsycINFO, PASCAL, FRANCIS, and BDSP databases were searched. All titles and abstracts were reviewed. A standardized extraction form was developed. All included studies were reviewed by 2 reviewers blinded to each other., Results: Sixteen studies were identified, and these reported 15 interventions. The objectives were to increase cancer screening participation (n = 7), early consultation (n = 1), and aftercare/quality of life among cancer survivors (n = 7). Six reported a complete participatory planning group, and 7 described a complete logic model of the problem. Ten studies described a complete logic model of change. The main theoretical frameworks used were the theory of planned behaviour (n = 8), the transtheoretical model (n = 6), the health belief model (n = 6), and the social cognitive theory (n = 6). The environment was rarely integrated in the interventions (n = 4). Five interventions were reported as effective., Conclusions: Culturally relevant interventions were developed with the IM protocol that were effective to increase cancer screening and reduce social disparities, particularly when they were developed through a participative approach and integrated the environment. Stakeholders' involvement and the role of the environment were heterogeneously integrated in the interventions., (Copyright © 2017 John Wiley & Sons, Ltd.)

Return to work (RTW) is an important step for breast cancer survivors (BCSs). However, they face many barriers that affect particularly women with low socioeconomic status (SES). Health care, workplace, and insurance actors lack knowledge and collaborate poorly. No intervention to date has proven effective to reduce social disparities in employment after breast cancer. The intervention mapping (IM) protocol is being used in France to develop, implement, and evaluate an intervention to facilitate and sustain RTW after breast cancer [ FAciliter et Soutenir le retour au TRAvail après un Cancer du Sein (FASTRACS) project]. The research question of this study was to elicit the needs for RTW after breast cancer from various stakeholders' point of view. The aim of this study was to describe the process and the preliminary results of the needs assessment of the FASTRACS project. Different methods were followed to (a) establish and work with a planning group and (b) conduct a needs assessment to create a logic model of the problem. A planning group was organized to gather the stakeholders with the research team. A review of the literature and indicators was conducted to identify the magnitude of the problem and the factors influencing RTW. A qualitative inquiry was conducted with 12 focus groups and 48 individual semi-structured interviews to explore the needs and experience of the stakeholders. The results of these tasks were the proposition of a charter of partnership to structure the participative process, a review of the scientific evidence and indicators, and the description by the stakeholders of their needs and experience. Many stakeholders disagreed with the concept of "early intervention." They advocated for a better support of BCSs during their RTW, emphasized as a process. Anticipation, intersectoral collaboration, and workplace accommodation were mentioned to fit the needs of the BCS and their environment. A logic model of the problem was elaborated from these data. The ability of the model to consider specific characteristics of women with low SES is discussed, with a view to developing the FASTRACS intervention through the next steps of the IM protocol.

Purpose: Sickness certification implies that a health problem impairs ability to work. However, its assessment is seldom performed by physicians. Our objective was, therefore, to assess the specific influence of functional and environmental limitations on the length of sick-leave prescriptions., Method: We conducted a cross-sectional study in French general teaching practices and recorded 353 initial sick-leave certifications. For each of them, the functional and environmental limitations were collected using the ATCIF questionnaire, derived from the International Classification of Functioning. Data analysis was based on a linear regression multivariate model., Results: Among the functional limitations, "pain" was the main body function impairment (22% of impairments) and "mobility" the main activity limitation (48%). An environmental barrier was identified in 39% of sick-listed patients, mainly relating to "products and technology" (20%), which refers to workplace factors. The prescription was longer in cases of activity limitations relating to "mobility" and in cases of environmental barriers relating to "products and technology". The multivariate model explained 27% of the variability of sick-leave length through diagnosis elements and only 7% through functional and contextual elements., Conclusion: In sick-leave prescription, a functional and contextual approach, in addition to the traditional diagnosis-based approach, could better support patients' shared understanding and follow-up, and accountability towards health authorities. Implication for Rehabilitation Although sickness certification implies that a health problem impairs ability to work, decision on sick-leave length in general practice is primarily based on diagnosis. A more functional and contextual approach could better support patients' and other health professionals' shared understanding and follow-up, and accountability towards health authorities. Such evolution requires a change of paradigm in medical education, and the way of reasoning of healthcare professionals.

The qualitative-quantitative study investigates the co-existence of barriers and levers to FOBT screening in 5894 individuals reluctant to be screened, identifying operational motivational patterns that may increase screening compliance. Co-occurrence analysis was performed according to three motivational conditions (barriers, levers, or both).Cluster analysis then identified motivational predictors of effective screening. One quarter of the individuals who had refused screening nevertheless expressed at least one motivation towards FOBT. As such, co-existence of barriers and levers within the same individual demonstrates ambivalence tendencies. Intrinsic motivations appear to be the most likely to increase FOBT compliance. This study finds that certain factors well-known to improve CRC screening compliance generally, may not have much impact on reluctant individuals due to ambivalence and contextual nuances. Several practical recommendations to encourage screening participation are offered, such as focusing on levers rather barriers, providing tailored education to improve awareness and readiness, and fostering intrinsic motivation with relevant approaches., (Copyright © 2017 Elsevier Inc.
