[Patient decision aids for cancer prevention Synthesis for the francophone community]. / Outils d'aide à la décision pour la prévention des cancers. Synthèse pour la francophonie.

In recent years, the relationship between patients and healthcare professionals, and more broadly between public health actors and citizens, has shifted from a paternalistic, top-down approach to one of increased patient involvement in decision-making. Primary and secondary cancer prevention involve both benefits and risks, underscoring the importance of informed decision-making aligned with each patient and citizen's unique values and preferences. Shared decision-making, supported by decision aids, offers patients and citizens clear and comprehensible information about their options, enabling informed choices. This article aims to compile and define the characteristics of tools developed or translated into French for this purpose.

Depuis plusieurs années, la relation entre les patients et les professionnels de la santé et plus largement entre les acteurs de la santé publique et les citoyens a évolué, passant d'une approche paternaliste et top-down à une implication accrue des patients dans les décisions les concernant. La prévention primaire et secondaire des cancers présente des bénéfices mais parfois également des risques, nécessitant une décision alignée avec les valeurs et les préférences des patients et des citoyens. La prise de décision partagée, via des outils d'aide à la décision, offre aux patients des informations claires et faciles à comprendre à propos des options qui leur sont offertes, afin de prendre une décision éclairée. Cet article vise à recenser les outils créés ou traduits en français et à en définir les caractéristiques.

[Scientific consensus-building to promote the link between science and public policy]. / La recherche de consensus scientifique pour promouvoir le lien entre science et politiques publiques.

Consensus, defined as the position on which most scientists specialized in a given field agree at a given time, is a key aspect in increasing the readability, credibility and, ultimately, the use of scientific knowledge in public (evidence-based health policy). This article presents several methods aiming at developing scientific consensus between experts, such as the conventional or rapid Delphi approach, the nominal group technique, the RAND-UCLA appropriateness method and the consensus development conference. These methods are used to synthesize expert judgements when uncertainties persist in the literature - each with its own specificities in terms of duration, number of steps and expert participants enlisted, as well as the ways in which they are involved.

Le consensus, défini comme la position sur laquelle la plupart des scientifiques spécialistes d'un domaine se mettent d'accord à un moment donné, est un aspect-clé pour augmenter la lisibilité, la crédibilité et in fine l'utilisation des savoirs scientifiques dans les politiques publiques (evidence-based health policy). Cet article présente plusieurs méthodes permettant le développement de consensus entre personnes expertes, telles que l'approche Delphi conventionnelle ou rapide, la technique du groupe nominal, la méthode d'adéquation RAND-UCLA et la conférence de consensus. Ces méthodes permettent la synthèse des jugements experts lorsque des incertitudes persistent dans la littérature ­ chacune avec des spécificités en termes de durée, du nombre d'étapes et de personnes expertes sollicitées, ainsi que des modalités de leur implication.

Why did Swiss citizens vote to ban tobacco advertising?

In February 2022, Swiss citizens agreed to modify the Swiss Constitution to ban tobacco advertising reaching children and adolescents. This case study analyses the arguments used by both opponents and supporters of the constitutional amendment. Opponents argued that the proposed regulation went too far, threatened the economy, restricted personal freedom, was superfluous as the current law already protected youth and that it opened the door to marketing bans of other harmful products. Proponents focused on youth protection and invoked the burden of smoking on public health and the fact that advertising bans are an effective evidence-based measure. A comparison with previous campaigns to ban tobacco advertising that had failed suggests factors accounting for the positive vote in 2022. These include the strategic framing of youth protection, the separation of tobacco from other issues (such as alcohol advertising), the deteriorating image of the tobacco industry and the ability of the proponents to mobilise a broad coalition of health and youth organisations, with improved funding and communication. The lessons may be instructive for other campaigns seeking to regulate commercial determinants of health.

Antigen rapid tests, nasopharyngeal PCR and saliva PCR to detect SARS-CoV-2: A prospective comparative clinical trial.

BACKGROUND: Nasopharyngeal antigen Rapid Diagnostic Tests (RDTs), saliva RT-PCR and nasopharyngeal (NP) RT-PCR have shown different performance characteristics to detect patients infected by SARS-CoV-2, according to the viral load (VL)-and thus transmissibility. METHODS: In October 2020, we conducted a prospective trial involving patients presenting at testing centres with symptoms of COVID-19. We compared detection rates and performance of RDT, saliva PCR and nasopharyngeal (NP) PCR, according to VL and symptoms duration. RESULTS: Out of 949 patients enrolled, 928 patients had all three tests performed. Detection rates were 35.2% (95%CI 32.2-38.4%) by RDT, 39.8% (36.6-43.0%) by saliva PCR, 40.1% (36.9-43.3%) by NP PCR, and 41.5% (38.3-44.7%) by any test. For those with viral loads (VL) ≥106 copies/ml, detection rates were 30.3% (27.3-33.3), 31.4% (28.4-34.5), 31.5% (28.5-34.6), and 31.6% (28.6-34.7%) respectively. Sensitivity of RDT compared to NP PCR was 87.4% (83.6-90.6%) for all positive patients, 94.5% (91.5-96.7%) for those with VL≥105 and 96.5% (93.6-98.3%) for those with VL≥106. Sensitivity of STANDARD-Q®, Panbio™ and COVID-VIRO® Ag tests were 92.9% (86.4-96.9%), 86.1% (78.6-91.7%) and 84.1% (76.9-89.7%), respectively. For those with VL≥106, sensitivity was 96.6% (90.5-99.3%), 97.8% (92.1-99.7%) and 95.3% (89.4-98.5%) respectively. No patient with VL<104 was detected by RDT. Specificity of RDT was 100% (99.3-100%) compared to any PCR. RDT sensitivity was similar <4 days (87.8%, 83.5-91.3%) and ≥4 days (85.7%, 75.9-92.6%) after symptoms onset (p = 0.6). Sensitivity of saliva and NP PCR were 95.7% (93.1-97.5%) and 96.5% (94.1-98.1%), respectively, compared to the other PCR. CONCLUSIONS: RDT results allow rapid identification of COVID cases with immediate isolation of most contagious individuals. RDT can thus be a game changer both in ambulatory care and community testing aimed at stopping transmission chains, and even more so in resource-constrained settings thanks to its very low price. When PCR is performed, saliva could replace NP swabbing. TRIAL REGISTRATION: ClinicalTrial.gov Identifier: NCT04613310 (03/11/2020).

[New puff-like disposable electronic cigarettes: expert consensus on their regulation]. / Nouvelles cigarettes électroniques jetables « puffs ¼ : consensus d'expert-e-s sur leur réglementation.

New disposable electronic cigarettes have arrived on the Swiss market since 2020. Our study, conducted according to the three steps of the Delphi fast-track approach developed at Unisanté, obtained a consensual agreement among French-speaking Switzerland experts on the regulation of these products. Ideally, the panel of experts recommends a sales ban of the product. If this is not possible, a number of aspects should be strictly regulated: taxation, product composition and marketing, and sales and consumption restrictions. These regulations should go further than the current European directive and the future Swiss law. The conclusions will be useful to support and guide political decision making from a public health and environmental perspective.

De nouvelles cigarettes électroniques jetables sont arrivées sur le marché suisse depuis 2020. Notre étude, conduite selon les trois étapes de la démarche Delphi fast-track développée à Unisanté, a obtenu un accord consensuel entre expert-e-s suisses romand-e-s sur la réglementation de ces produits. Dans l'idéal, le panel d'expert-e-s recommande une interdiction de vente du produit. Si cela n'est pas possible, certains aspects doivent être strictement réglementés : taxation, composition des produits et marketing, restrictions de vente et de consommation. Ces réglementations devraient aller plus loin que l'actuelle directive européenne et la future loi suisse. Les conclusions seront utiles pour soutenir et orienter la prise de décision politique dans une perspective de santé publique et environnementale.

Cigarette smoking during pregnancy and adverse perinatal outcomes: a cross-sectional study over 10 years.

BACKGROUND: It has been shown that active exposure to tobacco is associated with adverse pregnancy outcomes including, but not limited to, intrauterine fetal death, reduced fetal weight, and higher risk of preterm birth. We want to investigate these effects in a high-income country. METHODS: This cross-sectional study examined 20,843 pregnant women who delivered over 10 years at the Maternity Hospital of the Centre Hospitalier Universitaire Vaudois (CHUV) in Lausanne, Switzerland. The objective was to evaluate a dose-response relationship between daily cigarette use during pregnancy and possible adverse perinatal outcomes. The social and clinical characteristics as well as obstetric and neonatal outcomes were compared between the smoking and the non-smoking groups. Adjusted odds ratios (aOR) and trend analyses (ptrend) were calculated. RESULTS: Nineteen thousand five hundred fifty-four pregnant women met the inclusion criteria and 2,714 (13.9%) of them were smokers. Even after adjusting for confounding factors, smoking during pregnancy was associated with preterm birth, birthweight < 2500 g, intrauterine growth restriction, neonatal respiratory and gastrointestinal diseases, transfer to the neonatal intensive care unit, and neonatal intensive care unit admissions > 7 days. Intrauterine death and neonatal infection were associated with heavy smoking (≥ 20 cigarettes/day). Smoking appeared to be a protective factor for pre-eclampsia and umbilical cord arterial pH below 7.1. A significant trend (ptrend < 0.05) was identified for preterm birth, intrauterine growth restriction, birthweight < 2500 g, umbilical cord arterial pH below 7.1, transfers to our neonatal intensive care unit, and neonatal intensive care unit admissions more than 7 days. CONCLUSION: Cigarette smoking is associated with several adverse perinatal outcomes of pregnancy with a dose-dependent effect.

[Risk assessment and management: between epidemiology and social acceptability]. / Évaluation et gestion des risques : entre épidémiologie et acceptabilité sociale.

Risk is a well-known concept in medicine and in epidemiology and its approach intend to be rational and measurable. Risk measurement makes it possible to communicate with a patient or a population the risk of occurrence of an event. However, it is often difficult to estimate accurately the probability of occurrence of an adverse event and there is therefore uncertainty. In addition, the notion of risk is not easy to grasp for most people. The same risk can be perceived very differently from one individual to another and this perception and understanding depends on psychological, social, cultural, historical and political factors. Understanding this social dimension of risk in clinical practice or in public health is essential to implement efficient risk management.

La notion de risque est bien connue en médecine et en épidémiologie et son approche se veut rationnelle et mesurable. Cette mesure du risque permet de communiquer à un patient ou à une population le risque de survenue d'un événement. Mais il est souvent difficile d'estimer avec précision la probabilité de survenue d'un événement et il existe donc de l'incertitude. De plus, la notion de risque n'est pas facile à appréhender pour la plupart des personnes. Un même risque pourra être perçu très différemment d'un individu à l'autre et ces perception et compréhension des risques dépendent de facteurs psychologiques, sociaux, culturels, historiques et politiques. Bien comprendre cette dimension sociale du risque est essentiel pour appréhender une gestion des risques, que ce soit en clinique ou en santé publique.

Nicotine Replacement Therapy for Smokers with Acute Aneurysmal Subarachnoid Hemorrhage: An International Survey.

INTRODUCTION: Smoking prevalence is twice as high among patients admitted to hospital because of the acute condition of aneurysmal subarachnoid hemorrhage (aSAH) as in the general population. Smoking cessation may improve the prognosis of aSAH, but nicotine replacement therapy (NRT) administered at the time of aSAH remains controversial because of potential adverse effects such as cerebral vasospasm. We investigated the international practice of NRT use for aSAH among neurosurgeons. METHODS: The online SurveyMonkey software was used to administer a 15-question, 5-min online questionnaire. An invitation link was sent to those 1425 of 1988 members of the European Association of Neurosurgical Societies (EANS) who agreed to participate in surveys to assess treatment strategies for withdrawal of tobacco smoking during aSAH. Factors contributing to physicians' posture towards NRT were assessed. RESULTS: A total of 158 physicians from 50 nations participated in the survey (response rate 11.1%); 68.4% (108) were affiliated with university hospitals and 67.7% (107) practiced at high-volume neurovascular centers with at least 30 treated aSAH cases per year. Overall, 55.7% (88) of physicians offered NRT to smokers with aSAH, 22.1% (35) offered non-NRT support including non-nicotine medication and counselling, while the remaining 22.1% (35) did not actively support smoking cessation. When smoking was not possible, 42.4% (67) of physicians expected better clinical outcomes when prescribing NRT instead of nicotine deprivation, 36.1% (57) were uncertain, 13.9% (22) assumed unaffected outcomes, and 7.6% (12) assumed worse outcomes. Only 22.8% (36) physicians had access to a local smoking cessation team in their practice, of whom half expected better outcomes with NRT as compared to deprivation. CONCLUSIONS: A small majority of the surveyed physicians of the EANS offered NRT to support smoking cessation in hospitalized patients with aSAH. However, less than half believed that NRT could positively impact clinical outcome as compared to deprivation. This survey demonstrated the lack of consensus regarding use of NRT for hospitalized smokers with aSAH.

Risk of neonatal hypothyroidism in newborns from mothers exposed to CTPA during pregnancy: Ancillary data from a prospective outcome study.

BACKGROUND: Neonatal hypothyroidism is often raised as a potential concern for the use of computed tomography pulmonary angiography (CTPA) in pregnant women with suspected pulmonary embolism (PE). OBJECTIVES: To assess the incidence of neonatal hypothyroidism among newborns from mothers exposed to CTPA. PATIENTS/METHODS: Pregnant women with clinically suspected PE were included in a multicenter, multinational prospective diagnostic management outcome study, based on pretest clinical probability assessment, high-sensitivity D-dimer testing, bilateral lower limb venous compression ultrasonography, and CTPA. Results of Guthrie tests were systematically collected for newborns of all women who required CTPA as part of the diagnostic strategy. A thyroid-stimulating hormone (TSH) level above 15 U/ml was used to define hypothyroidism. RESULTS: Out of the 166 women included in the Swiss participating centers, 149 underwent a CTPA including 14 with twin pregnancies. Eight women suffered a pregnancy loss and results of the Guthrie test could not be retrieved for four newborns. All TSH levels were reported as being below 15 U/ml. The incidence of neonatal hypothyroidism was 0/151 (0.0%, 95% confidence interval: 0.0%-2.5%). CONCLUSIONS: We did not identify any cases of neonatal hypothyroidism in our cohort of 149 pregnant women investigated for suspected PE using a CTPA. Along with previous literature data, this provides further reassuring data regarding the use of CTPA in this indication.

Investigating acceptability of a training programme in precision medicine for frontline healthcare professionals: a mixed methods study.

BACKGROUND: Precision Medicine offers tailored prevention, diagnosis, treatment and management to patients that considers genomics, lifestyle and environmental factors. If implementation of Precision Medicine is to advance, effective, focused upskilling of frontline healthcare professionals through quality continuing professional development is needed. This study reports on an evidence-based approach to needs assessment to investigate the current level of knowledge of Precision Medicine, acceptable content for training, the perceived potential of a more precision approach to patient care and motivation to participate in a training programme among pharmacists, advanced practice nurses and general practitioners. Investigating perceived needs can avoid a top-down approach and support a design that is fit for purpose to targeted professions. METHODS: This study reports on 2 focus groups (n = 12) delivered in French and German with equal professional participation of the targeted professions. The research objectives were investigated in two phases. During the first phase, a literature review and expert consultations were conducted to develop a definition of PM, patient cases and content for training. In a second phase, these investigations were further explored using focus groups to investigate acceptable learning objectives, the potential of PM to relevant professions and motivation of participants. Quantitative investigations using rating scales and visual analogues were incorporated. The focus groups were audio recorded, transcribed by intelligent verbatim and translated to English. NVivo was used for data analysis and interpretation following a hybrid approach using the Framework Method and thematic analysis. The analytical framework, Implementation Science, was applied to organise and present research data. RESULTS: Precision Medicine is considered a new topic area, largely unfamiliar to frontline healthcare professionals.. There was acceptance of a more precision approach to care among all participants with perceived positive implications for patients. Valuable insight was gathered on acceptable content and form for training. All participants expressed concerns on readiness within their professions which included an insufficient system infrastructure, a lack of time to attend needed training, a lack of clarity for use in practice and the time needed to build a support network. CONCLUSIONS: A precision approach to patient care is on the horizon for health care professionals not only in hospital settings but also at the community level. Our results conclude that an adaptable and flexible training programme in PM is timely, contextually relevant and conducive to the needs of targeted health professions for successful implementation. A training programme in PM will require support across sectors and stakeholders, supporting insurance models, educated patients and integrated care supported by innovative technology. Implementation Science outcomes are a useful strategy towards design of an effective training programme that can have measurable impact in practice.

The neighborhood environment and its association with the spatio-temporal footprint of tobacco consumption and changes in smoking-related behaviors in a Swiss urban area.

This study aimed to evaluate the association of the neighborhood environment with the spatio-temporal dependence of tobacco consumption and changes in smoking-related behaviors in a Swiss urban area. Data were obtained from the CoLaus cohort (2003-2006, 2009-2012, and 2014-2017) in Lausanne, Switzerland. Local Moran's I was performed to assess the spatial dependence of tobacco consumption. Prospective changes in tobacco consumption and the location of residence of participants were assessed through Cox regressions. Analyses were adjusted by individual and neighborhood data. The neighborhood environment was spatially associated with tobacco consumption and changes in smoking-related behaviors independently of individual factors.
