Risk-adjusted trend in national inpatient fall rates observed from 2011 to 2019 in acute care hospitals in Switzerland: a repeated multicentre cross-sectional study.

OBJECTIVES: This study aimed to investigate whether a significant trend regarding inpatient falls in Swiss acute care hospitals between 2011 and 2019 could be confirmed on a national level, and whether the trend persists after risk adjustment for patient-related fall risk factors. DESIGN: A secondary data analysis was conducted based on annual multicentre cross-sectional studies carried out between 2011 and 2019. SETTING: All Swiss acute care hospitals were obliged to participate in the surveys. Except for emergency departments, outpatient wards and recovery rooms, all wards were included. PARTICIPANTS: All inpatients aged 18 or older who had given their informed consent and whose data were complete and available were included. OUTCOME MEASURE: Whether a patient had fallen in the hospital was retrospectively determined on the survey day by asking patients the following question: Have you fallen in this institution in the last 30 days? RESULTS: Based on data from 110 892 patients from 222 Swiss hospitals, a national inpatient fall rate of 3.7% was determined over the 9 survey years. A significant linear decreasing trend (p=0.004) was observed using the Cochran-Armitage trend test. After adjusting for patient-related fall risk factors in a two-level random intercept logistic regression model, a significant non-linear decreasing trend was found at the national level. CONCLUSIONS: A significant decrease in fall rates in Swiss hospitals, indicating an improvement in the quality of care provided, could be confirmed both descriptively and after risk adjustment. However, the non-linear trend, that is, an initial decrease in inpatient falls that flattens out over time, also indicates a possible future increase in fall rates. Monitoring of falls in hospitals should be maintained at the national level. Risk adjustment accounts for the observed increase in patient-related fall risk factors in hospitals, thus promoting a fairer comparison of the quality of care provided over time.

The impact of gendered experiences on the career choice of swiss medical students: A qualitative study protocol.

The problem of gender discrimination and sexual harassment in medicine is long-standing and widespread. This project aims to document and understand how gendered experiences encountered by final-year medical students in Switzerland are experienced by these individuals and how they influence their career choice. It also aims to identify representations and stereotypes linked to the different specialties. The project will take place at all Swiss universities offering a master's degree in human medicine, for a total of 9 programs. Around 36 participants will be recruited. Semi-structured qualitative individual interviews will be conducted. Analysis will be based on Grounded Theory principles.

Prevalence and characteristics of medical emergency teams in Switzerland: a nationwide survey of intensive care units.

BACKGROUND: Medical Emergency Teams (METs) have been implemented in many hospitals worldwide and are considered an integral part of the hospital patient safety system. However, data on prevalence, staffing and activation criteria of METs are scarce. Such data are important as they may help to identify areas of quality improvement and barriers to implementation of rapid response systems (RRS). This survey aimed to analyze current characteristics, prevalence, and organization of METs in Switzerland. METHODS: We conducted a cross-sectional nationwide online survey, inviting physicians' and nurses' representatives from all registered adult intensive care units (ICU) in Switzerland. RESULTS: Of the 74 hospitals invited to participate in the survey, 57 responded (response rate 77%). We obtained 82 individual responses (from 50 physicians and 32 nurses). Twenty-five hospitals (44%) have a MET in place. In most Swiss hospitals, METs are composed of ICU consultants (64%) and ICU nurses (40%) and are activated by phone, with a usual response time of less than 10 minutes. The most common triggers are single abnormal vital signs (80%), while multiple-parameter warning scores are less commonly used (28%). While more than half of the nurses have regular trainings for their MET members (57%), most MET physicians (63%) do not. Systematic data collection of MET calls occurs in only 43% of institutions. Finally, the most common reasons for not having a MET are staff shortage (44%) and lack of funding (19%). CONCLUSIONS: Less than 50% of Swiss hospitals with an adult ICU have a MET in place. METs in Switzerland typically include an ICU doctor and an ICU nurse and are available 24/7. Major barriers to MET introduction are staff shortage and lack of funding.

Exploring evidence use and capacity for health services management and planning in Swiss health administrations: A mixed-method interview study.

BACKGROUND: Health administrations require evidence, meaning robust information, data, and research, on health services and systems. Little is known about the resources and processes available within administrations to support evidence-informed policymaking. This study assessed Swiss health administrations' capacity for evidence use and investigated civil servants' needs and perspectives regarding the role and use of evidence in health services management and planning. METHODS: In this mixed-method study, we interviewed civil servants from Swiss German-speaking cantonal health administrations. We quantitatively assessed administrations' organization-level capacity by applying six structured interviews using an existing measurement tool (ORACLe). Individual-level needs and perspectives regarding evidence use and capacity were qualitatively explored with twelve in-depth interviews that were analyzed using the framework method. FINDINGS: Respondents indicated moderate evidence-use capacity in all administrations. Administrations displayed a similar pattern of high and low capacity in specific capacity areas, generally with considerable variation within administrations. Most administrations indicated high capacity for producing or commissioning evidence and close relationships with research. They showed limited capacity in the documentation of processes and availability of tools, programs, or training opportunities. Administrations place the responsibility for engagement with evidence at the level of individual civil servants rather than at the organizational level. Although administrations highly value evidence-informed policymaking and consider it vital to effective health services management and planning, they face significant constraints in accessing evidence-specific resources and receive little organizational support. Administrations rely on external capacity to compensate for these limitations and engage with evidence pragmatically. CONCLUSION: Our findings indicate moderate and improvable capacity for evidence use in Swiss health administrations that place limited value on organizational support. Besides strengthening organizational support, leadership buy-in, particular staff needs, and balancing the implementation of specific measures with the provision of more general resources should be considered to unlock the potential of strengthened engagement with evidence.

Diphtheria in a Swiss Asylum Seeker Reception Centre: Outbreak Investigation and Evaluation of Testing and Vaccination Strategies.

Objectives: To describe a suspected diphtheria outbreak in a Swiss asylum seeker reception centre, and to analyse its management response regarding testing and vaccination. Methods: We retrospectively analysed clinical, microbiology, and case management data of all asylum seekers tested for C. diphtheriae between 28th August and 31st December 2022 while residing at the centre. Results are reported descriptively. Results: Among 265 individuals tested, ten cases of cutaneous diphtheria, one simultaneous respiratory and cutaneous case, and nine respiratory carriers were identified. Mass throat screening, targeted throat testing and targeted wound testing yielded 4.8%, 4.3%, and 17.4% positive results, respectively. No respiratory carrier was identified among cutaneous cases undergoing a throat swab, and no symptomatic case was identified among individuals with unspecific throat symptoms. Rates of vaccination implementation of newly arriving asylum seekers before and after the outbreak were low (17.5% and 15.5%, respectively), as were rates of targeted vaccination among cases and close contacts. Conclusion: We provide evidence for transmission both prior to arrival and within the setting, suboptimal practices and timeliness of testing, and implementation gaps in vaccination.

Evaluation of serological assays for the diagnosis of childhood tuberculosis disease: a study protocol.

BACKGROUND: Tuberculosis (TB) poses a major public health challenge, particularly in children. A substantial proportion of children with TB disease remain undetected and unconfirmed. Therefore, there is an urgent need for a highly sensitive point-of-care test. This study aims to assess the performance of serological assays based on various antigen targets and antibody properties in distinguishing children (0-18 years) with TB disease (1) from healthy TB-exposed children, (2) children with non-TB lower respiratory tract infections, and (3) from children with TB infection. METHODS: The study will use biobanked plasma samples collected from three prospective multicentric diagnostic observational studies: the Childhood TB in Switzerland (CITRUS) study, the Pediatric TB Research Network in Spain (pTBred), and the Procalcitonin guidance to reduce antibiotic treatment of lower respiratory tract infections in children and adolescents (ProPAED) study. Included are children diagnosed with TB disease or infection, healthy TB-exposed children, and sick children with non-TB lower respiratory tract infection. Serological multiplex assays will be performed to identify M. tuberculosis antigen-specific antibody features, including isotypes, subclasses, Fc receptor (FcR) binding, and IgG glycosylation. DISCUSSION: The findings from this study will help to design serological assays for diagnosing TB disease in children. Importantly, those assays could easily be developed as low-cost point-of-care tests, thereby offering a potential solution for resource-constrained settings. GOV IDENTIFIER: NCT03044509.

Navigating HIV-Related Stigma in Switzerland: A Qualitative Study.

Objectives: This study sought to understand how people living with HIV experience, perceive, and navigate stigma in their everyday life and in care settings in an urban French-speaking area in Switzerland. Methods: Semi-structured interviews were carried out with 19 people living with HIV in Lausanne concerning their experience of HIV-related stigma in both everyday life and in healthcare settings. Content analysis was performed to identify main and sub-themes. Results: "Living with HIV" posed little or no difficulty for participants. However, the burden of anticipated and internalized HIV-related stigma played a disproportionately large role in their lives. Participants considered the general population's low level of knowledge about HIV as problematic in this regard. While participants reported few examples of enacted stigma generally, healthcare environments were sometimes experienced as sites of prejudice and discrimination. However, some healthcare professionals were also sources of information and knowledge, contributing to participants' "journeys of self-acceptance." Conclusion: Even in an urban environment in a country with ready access to healthcare and education, HIV-related stigma remains a concern for people living with HIV.

Early and late implant loss in a university-based periodontal setting: A retrospective analysis on 1821 patients and 2639 implants over a period of 18 years.

The aim of this study was to retrospectively analyze the implant failure rate, not due to peri-implantitis, in periodontally compromised patients rehabilitated with at least one dental implant placed in a specialist university setting over the last 18 years. Records of patients receiving dental implants at the Department of Periodontology, University of Bern, Switzerland, between 2005 and 2022 were analyzed. Data on 1821 patients with 2639 implants were retrieved. Fifty-nine patients experienced implant loss (rate at patient level: 3.2%) out of which 2.1% were early and 1.1% late implant losses, respectively. The majority of the 59 patients were males (68%) and 27.1% were smokers. Eight mm implants were lost with the highest rate (42.4%) followed by 10 mm implants (31.8%). The rate of lost maxillary implants was more than twice as high compared with that of mandibular implants (69.7 vs. 30.3%). Within the study limitations, the implant failure rate in this cohort of patients enrolled in regular supportive periodontal and peri-implant care, was low.

Oral health and nutritional status in care-dependent, community-dwelling older adults in Zurich, Switzerland.

The aim of this study was to assess the oral health status (OHS), Oral health impact profile (OHIP-G-14), and the nutritional status (NS) in community-dwelling, dependent older adults. Information on OHS including DMF(T), plaque (PI) and gingival (GI) indices, community-periodontal-index-for-treatment-needs (CPITN), OHIP-G-14, maximum bite force (MBF), chewing efficiency [subjective (SA) and quantitative (VoH) assessments] were collected. NS was obtained by Mini-nutritional assessment (MNA) and body mass index (BMI). Cognitive status was evaluated by the mini-mental state examination (MMSE). 240 elders (mean-age = 81.5 ± 8.9y; men =85, women =155) were recruited. Average number of teeth, functional occlusal units and DMF(T), were 18.8 ± 8.9, 7.7 ± 3.5, and 22.3 ± 5.3 respectively. Mean PI, GI, CPITN and OHIP-G-14 were 1.8 ± 0.8, 1.2 ± 0.8, 1.9 ± 1.1, and 8.0 ± 12.0, respectively. MBF, VoH, SA were 219.6 ± 193.6, 0.3 ± 0.2, and 3.3 ± 1.4, respectively. MNA and BMI were 22.9 ± 4.7 and 25.5 ± 5.3, respectively. Number of teeth reduced significantly with age (P < 0.001), cognitive decline (P < 0.001). Oral hygiene significantly deteriorated with cognitive decline (P < 0.001). OHIP scores were negatively affected by increasing cognitive decline (P < 0.001). MNA deteriorated in women (P = 0.026), with increasing age (P = 0.015), and advancing cognitive decline (P < 0.001). BMI reduced with advancing age (P = 0.003) and in women (P = 0.016). Based on the findings of this study, it may be concluded that advancing age and cognitive decline, negatively impacted the oral health, oral function, oral health-related quality of life, and the nutritional state of care-dependent community-dwelling older adults.

Removable dental prostheses and difficulties with chewing among frail individuals: Results from the Swiss SAPALDIA cohort.

Oral healthcare among the frail is an underestimated geriatric care element. While neglected oral health (OH) is a well-established risk factor for frailty, frailty can be a risk factor for subsequent OH problems. The cross-sectional investigation nested into the SAPALDIA sub-cohort of citizens aged 52 years and older, aims to stimulate longitudinal research into aspects that accelerate poor OH among frail individuals. The hypothesis investigated was that (pre-) frail individuals are more likely to have missing teeth replaced with removable dental prostheses (RDP) resulting in difficulties with chewing. The study included 1489 participants undergoing geriatric assessments and oral examination. The main predictor was frailty status (non-frail; pre-frail; frail), based on Fried's frailty phenotype. The main outcomes of interest were non-functional dentition (presence of ≤ 19 natural teeth), presence of any RDP and self-reported difficulties with chewing. Pre-frailty and frailty were not associated with the presence of ≤ 19 natural teeth, but were associated with a higher RDP prevalence. The presence of at least one complete denture (CD) had 1.71 fold and 2.54 folds higher odds among pre-frail and frail, respectively, compared to non-frail individuals. Frail individuals with CD reported chewing difficulties 7.8 times more often than non-frail individuals without CD. The results are in line with the hypothesis that (pre-) frail individuals may be more likely to have tooth loss restored by RDPs. Future longitudinal research needs to assess potential barriers to oral hygiene and fixed dental prostheses among (pre-) frail and to study their oral health-related quality of life.

[Need for dentists with post-graduate training in endodontology according to members of the Swiss Dental Association].

This questionary-based study was financed by the Swiss Society for Endodontology (SSE). At the time of this survey (2022) there were merely 20 board-certified endodontists in Switzerland, and 239 other members of the SSE, i.e. general practitioners with some form of post-graduate endodontic training or a keen interest in the field. The aim of this investigation was to evaluate the need for a higher number of trained endodontists as viewed by the general population of dentists in Switzerland. An electronic questionary in either German, French, or Italian was sent to all 4072 active members of the Swiss Dental Association (SSO). The questionnaire focused on the background of the surveyed dentists, their willingness to refer endodontic cases to a specialist or colleague with a focus on endodontics, their propensity to do so, and their perceived need for endodontists in their region. The response rate was 21%, and was similar between the different regions and cantons. Seventy-nine (9%) of the dentists participating in the survey were members of the SSE, while 16 (2%) were board-certified. Merely 7% of the participants received endodontic referrals themselves, while 81% referred cases in some instances. However, only 13% of participants referred endodontic cases always or regularly. The main reason for not referring was the belief by the surveyed dentists that they could perform the endodontic treatments themselves. Long distance to the next endodontic specialist or expert was the second most frequently given reason not to refer cases. A total of 58% of the participants believed that there were enough endodontists in Switzerland to cover the encountered clinical problems.

Dental injuries in Swiss children - an analysis of Swiss national health insurance data from the year 2019.

This study, the first to analyze accident data from a major compulsory Swiss health insurer (Concordia), reviewed 5,063 dental accident reports of 122,370 children under the age of 16. The predominant cause of injury was a "fall," with "playing" being the foremost activity mentioned and "ground" identified as the primary object of impact. The analysis of the involved objects showed that dental injuries occur most frequently with scooters, bicycles, and stairs. In 2019, 8.14% of children aged one and insured by Concordia suffered a dental injury. By age 16, 58.8% of all children had experienced a dental injury. 0.72% had suffered a primary dentition crown fracture with pulp involvement. Regarding their permanent teeth, 0.21% suffered an avulsion, 0.84% another luxation injury, 0.65% a crown fracture with pulp involvement, and 0.16% a root fracture. A significant increase in injuries per day was observed after the summer holidays. On weekends, there were 28% fewer injuries per day on average than on weekdays. Despite differences among the cantons, the dataset can be considered to be representative for Switzerland. Accident descriptions were often too brief for detailed prevention strategies. Detailed accident information is essential for effective structural measures, which are more effective than promoting behavioural changes. A detailed recording could also be used to draw up a list of the objects frequently involved in accidents. An updated insurance form with an improved nomenclature, the option of digital submission, photo uploads and AI-supported data recording could greatly improve the quality and interpretability of injury data.

What Factors Contribute to Ethical Problems in Patient Care? A Scoping Review and Case Series of Clinical Ethics Consultations.

AbstractBackground: Healthcare professionals (HCPs) are frequently exposed to ethical problems in patient care that can affect the quality of care. Understanding risk factors for ethical problems may help practitioners to address these problems at an early stage. This study aims to provide an overview of ethical risk factors in patient care. Risk factors known from the literature and those found in clinical ethics consultation (CEC) cases are reviewed. METHODS: A scoping review of ethical risk factors in patient care and a CEC case series were conducted, analyzing the documentation (consultation reports, feedback forms, electronic medical records) of 204 CECs from 2012 to 2020 at a somatic and a psychiatric university hospital in Basel, Switzerland. RESULTS: Ninety-nine ethical risk factors were identified in nine articles, related to four risk areas: patient (41), family (12), healthcare team (29), and system (17). Eighty-seven of these risk factors were documented at least once in the CEC case series. The most prevalent risk factors in the consultations studied were patient vulnerability (100%), missing or unclear hospital ethics policy (97.1%), shift work (83.3%), lack of understanding between patient and HCP (73.5%), poor communication (66.2%), disagreement between patient and HCP about care (58.8%), and multiple care teams (53.4%). The prevalence differed significantly by medical specialty. CONCLUSIONS: There are highly prevalent ethical risk factors at all levels of clinical care that may be used to prevent ethical problems. Further empirical research is needed to analyze risk ratios and to develop specific risk profiles for different medical specialties.

Risk Assessment Models for Venous Thromboembolism in Medical Inpatients.

Importance: Thromboprophylaxis is recommended for medical inpatients at risk of venous thromboembolism (VTE). Risk assessment models (RAMs) have been developed to stratify VTE risk, but a prospective head-to-head comparison of validated RAMs is lacking. Objectives: To prospectively validate an easy-to-use RAM, the simplified Geneva score, and compare its prognostic performance with previously validated RAMs. Design, Setting, and Participants: This prospective cohort study was conducted from June 18, 2020, to January 4, 2022, with a 90-day follow-up. A total of 4205 consecutive adults admitted to the general internal medicine departments of 3 Swiss university hospitals for hospitalization for more than 24 hours due to acute illness were screened for eligibility; 1352 without therapeutic anticoagulation were included. Exposures: At admission, items of 4 RAMs (ie, the simplified and original Geneva score, the Padua score, and the IMPROVE [International Medical Prevention Registry on Venous Thromboembolism] score) were collected. Patients were stratified into high and low VTE risk groups according to each RAM. Main Outcomes and Measures: Symptomatic VTE within 90 days. Results: Of 1352 medical inpatients (median age, 67 years [IQR, 54-77 years]; 762 men [55.4%]), 28 (2.1%) experienced VTE. Based on the simplified Geneva score, 854 patients (63.2%) were classified as high risk, with a 90-day VTE risk of 2.6% (n = 22; 95% CI, 1.7%-3.9%), and 498 patients (36.8%) were classified as low risk, with a 90-day VTE risk of 1.2% (n = 6; 95% CI, 0.6%-2.6%). Sensitivity of the simplified Geneva score was 78.6% (95% CI, 60.5%-89.8%) and specificity was 37.2% (95% CI, 34.6%-39.8%); the positive likelihood ratio of the simplified Geneva score was 1.25 (95% CI, 1.03-1.52) and the negative likelihood ratio was 0.58 (95% CI, 0.28-1.18). In head-to-head comparisons, sensitivity was highest for the original Geneva score (82.1%; 95% CI, 64.4%-92.1%), while specificity was highest for the IMPROVE score (70.4%; 95% CI, 67.9%-72.8%). After adjusting the VTE risk for thromboprophylaxis use and site, there was no significant difference between the high-risk and low-risk groups based on the simplified Geneva score (subhazard ratio, 2.04 [95% CI, 0.83-5.05]; P = .12) and other RAMs. Discriminative performance was poor for all RAMs, with an area under the receiver operating characteristic curve ranging from 53.8% (95% CI, 51.1%-56.5%) for the original Geneva score to 58.1% (95% CI, 55.4%-60.7%) for the simplified Geneva score. Conclusions and Relevance: This head-to-head comparison of validated RAMs found suboptimal accuracy and prognostic performance of the simplified Geneva score and other RAMs to predict hospital-acquired VTE in medical inpatients. Clinical usefulness of existing RAMs is questionable, highlighting the need for more accurate VTE prediction strategies.

Long-term exposure to transportation noise and diabetes mellitus mortality: a national cohort study and updated meta-analysis.

BACKGROUND: Long-term exposure to transportation noise is related to cardio-metabolic diseases, with more recent evidence also showing associations with diabetes mellitus (DM) incidence. This study aimed to evaluate the association between transportation noise and DM mortality within the Swiss National Cohort. METHODS: During 15 years of follow-up (2001-2015; 4.14 million adults), over 72,000 DM deaths were accrued. Source-specific noise was calculated at residential locations, considering moving history. Multi-exposure, time-varying Cox regression was used to derive hazard ratios (HR, and 95%-confidence intervals). Models included road traffic, railway and aircraft noise, air pollution, and individual and area-level covariates including socio-economic position. Analyses included exposure-response modelling, effect modification, and a subset analysis around airports. The main findings were integrated into meta-analyses with published studies on mortality and incidence (separately and combined). RESULTS: HRs were 1.06 (1.05, 1.07), 1.02 (1.01, 1.03) and 1.01 (0.99, 1.02) per 10 dB day evening-night level (Lden) road traffic, railway and aircraft noise, respectively (adjusted model, including NO2). Splines suggested a threshold for road traffic noise (~ 46 dB Lden, well below the 53 dB Lden WHO guideline level), but not railway noise. Substituting for PM2.5, or including deaths with type 1 DM hardly changed the associations. HRs were higher for males compared to females, and in younger compared to older adults. Focusing only on type 1 DM showed an independent association with road traffic noise. Meta-analysis was only possible for road traffic noise in relation to mortality (1.08 [0.99, 1.18] per 10 dB, n = 4), with the point estimate broadly similar to that for incidence (1.07 [1.05, 1.09] per 10 dB, n = 10). Combining incidence and mortality studies indicated positive associations for each source, strongest for road traffic noise (1.07 [1.05, 1.08], 1.02 [1.01, 1.03], and 1.02 [1.00, 1.03] per 10 dB road traffic [n = 14], railway [n = 5] and aircraft noise [n = 5], respectively). CONCLUSIONS: This study provides new evidence that transportation noise is associated with diabetes mortality. With the growing evidence and large disease burden, DM should be viewed as an important outcome in the noise and health discussion.

Barriers, facilitators and needs to deprescribe benzodiazepines and other sedatives in older adults: a mixed methods study of primary care provider perspectives.

BACKGROUND: Benzodiazepines and other sedative hypnotic drugs (BSHs) are frequently prescribed for sleep problems, but cause substantial adverse effects, particularly in older adults. Improving knowledge on barriers, facilitators and needs of primary care providers (PCPs) to BSH deprescribing could help reduce BSH use and thus negative effects. METHODS: We conducted a mixed methods study (February-May 2023) including a survey, semi-structured interviews and focus groups with PCPs in Switzerland. We assessed barriers, facilitators and needs of PCPs to BSH deprescribing. Quantitative data were analyzed descriptively, qualitative data deductively and inductively using the Theoretical Domain Framework (TDF). Quantitative and qualitative data were integrated using meta-interferences. RESULTS: The survey was completed by 126 PCPs (53% female) and 16 PCPs participated to a focus group or individual interview. The main barriers to BSH deprescribing included patient and PCP lack of knowledge on BSH effects and side effects, lack of PCP education on treatment of sleep problems and BSH deprescribing, patient lack of motivation, PCP lack of time, limited access to cognitive behavioral therapy for insomnia and absence of public dialogue on BSHs. Facilitators included informing on side effects to motivate patients to discontinue BSHs and start of deprescribing during a hospitalization. Main PCP needs were practical recommendations for pharmacological and non-pharmacological treatment of sleep problems and deprescribing schemes. Patient brochures were wished by 69% of PCPs. PCPs suggested the brochures to contain explanations about risks and benefits of BSHs, sleep hygiene and sleep physiology, alternative treatments, discontinuation process and tapering schemes. CONCLUSION: The barriers and facilitators as well as PCP needs and opinions on patient material we identified can be used to develop PCP training and material on BSH deprescribing, which could help reduce the inappropriate use of BSHs for sleep problems.

[Is mortality an objective indicator for measuring the impact of an epidemic?: The example of Covid-19 in Switzerland]. / La mortalité est-elle un indicateur objectif pour mesurer l'impact d'une épidémie ?. L'exemple du Covid-19 en Suisse.

Measuring the health impact of an epidemic using appropriate indicators is necessarily complex. Mortality does not sum up all the issues, but at least it seems to be an objective indicator. There are, however, a number of different mortality indicators, which do not all convey the same message. During the Covid-19 epidemic in Switzerland, the mortality rate rose by 10.2% in 2020, while life expectancy fell by "only" 0.8%, or 8.3 months, a decline described as "modest" or "complete freefall" depending on when it was published. In reality, the population living in Switzerland in 2020 lost an average of "only" 2.4 days, as the epidemic did not last their entire lives. The use of such an indicator, in comparison with losses due to other factors, would enable us to better estimate the real impact of an epidemic.

Mesurer l'impact sanitaire d'une épidémie à l'aide d'indicateurs appropriés est forcément complexe. La mortalité ne résume pas tous les enjeux mais semble au moins être un indicateur objectif. Il existe cependant différents indicateurs de mortalité ne donnant pas tous le même message. Lors de l'épidémie de Covid-19 en Suisse, le taux de mortalité a augmenté de 10,2 % en 2020, alors que l'espérance de vie n'a diminué « que ¼ de 0,8 %, ou 8,3 mois, recul par ailleurs qualifié de « modeste ¼ ou de « chute libre ¼ selon quand il a été publié. En réalité, la population vivant en Suisse en 2020 n'a perdu en moyenne « que ¼ 2,4 jours car l'épidémie n'a pas duré toute sa vie. L'utilisation d'un tel indicateur, en comparaison avec les pertes dues à d'autres facteurs, permettrait une meilleure estimation de l'impact réel d'une épidémie.

[Physiotherapy challenges in the management of breast cancer]. / Place de la physiothérapie lors de cancer du sein.

Breast cancer claims fewer lives in Switzerland, but it profoundly impacts the quality of life, with various treatments carrying significant side effects. Cancer treatments include physiotherapy as soon as possible. Physiotherapist, movement expert, using physical activity, enhances survival rates, reduces treatment-related side effects, and improves quality of life. After surgery, it addresses pain, functional limitations, and lymphatic issues. In the long term, it not only reduces the risk of recurrence of cancer but also enhances post-treatment quality of life and aids in the reintegration with one's "new" body. It empowers patients to actively engage in their treatment, illness, and recovery.

Le cancer du sein en Suisse est fréquent et, si la survie s'améliore, les différents traitements ont des effets secondaires non négligeables et la qualité de vie est altérée. La physiothérapie s'intègre au sein des différents traitements du cancer, dès le diagnostic. Le physiothérapeute, expert du mouvement, utilise notamment l'activité physique qui permet d'accroître la survie, diminue les effets secondaires des traitements et améliore la qualité de vie. Après la chirurgie, la physiothérapie s'adresse aux douleurs, aux limitations fonctionnelles et aux dysfonctions lymphatiques. À long terme, cette prise en charge permet, outre de diminuer le risque de récidive, d'améliorer la qualité de vie après les traitements, et de réintégrer son « nouveau ¼ corps. Elle est une arme permettant à la patiente de devenir actrice de son traitement, de sa maladie et de sa guérison.

A joint penalized spline smoothing model for the number of positive and negative COVID-19 tests.

One of the key tools to understand and reduce the spread of the SARS-CoV-2 virus is testing. The total number of tests, the number of positive tests, the number of negative tests, and the positivity rate are interconnected indicators and vary with time. To better understand the relationship between these indicators, against the background of an evolving pandemic, the association between the number of positive tests and the number of negative tests is studied using a joint modeling approach. All countries in the European Union, Switzerland, the United Kingdom, and Norway are included in the analysis. We propose a joint penalized spline model in which the penalized spline is reparameterized as a linear mixed model. The model allows for flexible trajectories by smoothing the country-specific deviations from the overall penalized spline and accounts for heteroscedasticity by allowing the autocorrelation parameters and residual variances to vary among countries. The association between the number of positive tests and the number of negative tests is derived from the joint distribution for the random intercepts and slopes. The correlation between the random intercepts and the correlation between the random slopes were both positive. This suggests that, when countries increase their testing capacity, both the number of positive tests and negative tests will increase. A significant correlation was found between the random intercepts, but the correlation between the random slopes was not significant due to a wide credible interval.
