Colorectal cancer testing rates after implementation of an organised screening programme in Vaud, Switzerland.

AIMS OF THE STUDY: Canton Vaud, Switzerland, implemented an organised colorectal cancer  screening programme with colonoscopy and faecal occult blood tests in 2015, 4 to 6 years ahead of neighbouring cantons. Before its implementation, nearly half of Swiss citizens were already up to date with screening, primarily from opportunistic colonoscopies. We hypothesised that earlier implementation of an organised programme would be associated with greater increases in colorectal cancer testing rates. METHODS: We analysed Swiss health insurance claim data from CSS, a Swiss health insurer covering 16% of the Swiss population and 10% of canton Vaud. We stratified 50-69-year-olds into groups from Vaud, its four neighbouring cantons (Fribourg, Geneva, Neuchâtel and Valais), and the rest of Switzerland. We analysed overall, faecal occult blood test and colonoscopy testing rates for each year between 2010 and 2018. RESULTS: The overall testing rate increased from 7.6% in 2010 to 11.6% in 2018 (+4.0%) in Vaud, from 6.1% to 9.3% (+3.2%) in neighbouring cantons and from 7.4% to 8.6% (+1.2%) in the rest of Switzerland. The faecal occult blood test rate increased between 2016 and 2018 from 2.9% to 4.1% (+1.2%) in Vaud and from 1.7% to 2.6% (+0.9%) in neighbouring cantons, but it decreased from 3.1% to 1.5% (-1.6%) in the rest of Switzerland. The colonoscopy rate increased in all cantons, from 4.7% to 7.5% in Vaud (+2.8%), from 4.4% to 6.7% in neighbouring cantons (+2.3%) and from 4.3% to 7.1% in the rest of Switzerland (+2.8%). By 2018, 40% of faecal occult blood tests and 26% of colonoscopies in Vaud occurred in the organised programme. Those who completed an faecal occult blood test within the Vaud programme were younger, had fewer comorbidities and were more likely to have a high-deductible health plan than those tested outside the programme. CONCLUSIONS: Colorectal cancer testing rates increased between 2010 and 2018, with greater absolute increases in Vaud than in neighbouring cantons or the rest of Switzerland. Faecal occult blood test use increased in both Vaud and neighbouring cantons, possibly reflecting changes in testing patterns by general practitioners. By 2018, 40% of colonoscopies and 26% of faecal occult blood tests occurred within the screening programme.

Combining default choices and an encounter decision aid to improve tobacco cessation in primary care patients: protocol for a cluster-randomized trial.

BACKGROUND: While quitting smoking dramatically decreases overall mortality, general practitioners (GPs) are less likely to prescribe medications for smoking cessation than other cardiovascular risk factors. Guidelines recommend providers first assess patients' "readiness" to quit, an "opt-in" strategy, but only a minority of tobacco users are ready to quit on a given day. An "opt-out" strategy offering treatment as the default choice increased quit attempts in hospital and with pregnant women, but has not been tested in primary care. We will assess the efficacy of training GPs to offer treatment as the default choice using an encounter decision aid with current smokers seen in primary care. METHODS: This is a pragmatic cluster-randomized controlled superiority trial with block randomization at the GP level in private practice in French-speaking Switzerland. GPs will be blinded to the arm allocation. The intervention is a half-day training course teaching an 'opt-out' approach to smoking cessation using an encounter decision aid (paper or electronic). GPs in the enhanced usual care group receives a brief refresher training about smoking cessation without changing their behaviour. GPs in both arms will recruit 23 patients each prior to routine primary care visits. The primary outcome is the effect of consulting a GP who received the intervention on the 7-day, point prevalence, smoking abstinence 6 months after the baseline appointment. Secondary outcomes include continuous abstinence; number of quit attempts; use of smoking cessation aids; patient-perceived involvement in discussions; and changes in GP behaviour. Patient outcomes will be collected using paper and telephone questionnaires. Assuming 15% drop-out, recruiting 46 GPs with 23 patients each will give us 80% power to detect an increase in smoking cessation from 4% (control) to 10.5% (intervention), with an alpha < 0.05. DISCUSSION: GP visits are an opportunity to administer proven smoking cessation treatments. We hypothesize GPs offering smoking cessation treatment as the default choice using an encounter decision aid will increase the number of patients who quit. This study could significantly change our approach to smoking cessation in primary care. Default choices and the electronic decision aid are low-cost, easily diffusible interventions.

[Decision aids for addictions: the example of smoking cessation]. / Outils d'aide à la décision dans les addictions : lexemple du tabac.

Decision aids (DAs) help patients participate in healthcare decisions by improving knowledge and clarifying values and preferences, thus favoring a more active role in the decision process. DAs exist as a physical support (paper, DVD, audio) or computerized formats. They can be used independently by patients before and after consultations, or with a health professional during consultations. Unisanté has created a DA for use during consultations presenting available smoking cessation aids (www.howtoquit.ch). A local study showed that the DA is considered easy to use and useful by the doctors interviewed. The use of DAs in addictions to other substances, in conjunction with shared decision making, shows a favourable effect on the involvement of patients in their health and therapeutic adherence.

Les outils d'aide à la décision (AD) soutiennent les patient-e-s dans leurs choix médicaux en majorant leurs connaissances et en clarifiant leurs valeurs et préférences, ce qui leur permet de s'impliquer dans le processus décisionnel. Les AD existent en tant que supports physiques (papier, DVD) ou informatiques. Ils peuvent être utilisés par les patient-e-s avant/après la consultation ou avec le-la professionnel-le de santé durant la consultation. Unisanté a créé un AD présentant les aides à l'arrêt du tabac durant la consultation. Une étude locale a montré que l'usage de celui-ci a été jugé simple et utile par les médecins. L'utilisation d'AD dans les addictions à d'autres substances, renforcée par des entretiens de décision partagée, montre un effet favorable sur l'implication des patient-e-s et sur l'adhésion thérapeutique.

Formative Provider Testing of a New Encounter Decision Aid for Smoking Cessation: Questionnaire Study.

BACKGROUND: Smoking cessation is an essential part of preventing and reducing the risk of smoking-associated morbidity and mortality. However, there is often little time to discuss smoking cessation in primary care. Decision aids (DAs) designed for clinic visits (encounter DAs) need to be clear, short, and concise to optimize therapeutic education, increase interaction, and improve the therapeutic alliance. Such a DA for smoking cessation could potentially improve counseling and increase the use of pharmacological treatments. OBJECTIVE: We aimed to collect feedback on an electronic encounter DA that facilitates physician-patient interaction and shared decision-making for smoking cessation in primary care. METHODS: We developed an electronic, encounter DA (howtoquit.ch) from a paper version created by our team in 2017 following user-centered design principles. The DA is a 1-page interactive website presenting and comparing medications for tobacco cessation and electronic cigarettes. Each smoking cessation medication has a drop down menu that presents additional information, a video demonstration, and prescribing information for physicians. To test the DA, we submitted a questionnaire to approximately 20 general practitioner residents of an academic general medicine department, 5 general practitioners, and 6 experts in the field of smoking cessation. The questionnaire consisted of 4 multiple-choice and 2 free-text questions assessing the usability or acceptability of the DA, the acquisition of new knowledge for practitioners, the perceived utility in supporting shared decision-making, perceived strengths and weaknesses, and whether the participants would recommend the tool to other clinicians. RESULTS: In all, 6 residents, 3 general practitioners in private practice, and 2 tobacco cessation experts completed the questionnaire (N=11), with 4 additional experts providing open-text feedback. On the 11 questionnaires, the DA was rated as practical and intuitive (mean 4.6/5), and providers felt it supported shared decision-making (mean 4.4/5), as comparisons were readily possible. Inclusion of explanatory videos was seen as a bonus. Several changes were suggested, like grouping together similar medications and adding a landing page to briefly explain the site. Changes were implemented according to end-user comments. CONCLUSIONS: The overall assessment of the encounter DA by a group of physicians and experts was positive. The ultimate objective is to have the tool deployed and easily accessible for all to use.

[Three approaches to doctor-patient communication and prevention : Which model for which situation ?] / Trois approches de communication médecin-patient et prévention : quel modèle pour quelle situation ?

Doctors learn different communication approaches for use during prevention consultations to promote healthy habits, so as to set up a partnership and to promote patient autonomy. Three of these approaches are shared decision making, when there is more than one reasonable choice, motivational interviewing, principally for behaviour change and therapeutic education, a pedagogical approach helping patients develop skills so that they may have a better management of their chronic illness. This article presents an overview of the commonalities and the differences between these approaches, often considered separately, nevertheless they are complementary and in practice, using elements of all three during a consultation could improve preventative care.

Les médecins apprennent différentes approches de communication utilisées lors des consultations de prévention afin de promouvoir des comportements sains, créer un partenariat avec le patient et favoriser son autonomie. Trois des approches les plus courantes sont : la décision partagée lorsqu'il y a plus d'un choix raisonnable, l'entretien motivationnel pour le changement de comportement et l'éducation thérapeutique, une approche pédagogique visant le développement de compétence des patients pour une gestion optimale des maladies chroniques. Nous présentons ici une vision d'ensemble des similarités et des différences entre ces approches, car, souvent considérées en silos, elles sont néanmoins complémentaires et, en pratique, utiliser des éléments tirés des trois durant une consultation pourrait améliorer la prise en charge.
