Risk Factors for Recurrent Exacerbations in the General-Practitioner-Based Swiss Chronic Obstructive Pulmonary Disease (COPD) Cohort.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) often suffer from acute exacerbations. Our objective was to describe recurrent exacerbations in a GP-based Swiss COPD cohort and develop a statistical model for predicting exacerbation. METHODS: COPD cohort demographic and medical data were recorded for 24 months, by means of a questionnaire-based COPD cohort. The data were split into training (75%) and validation (25%) datasets. A negative binomial regression model was developed using the training dataset to predict the exacerbation rate within 1 year. An exacerbation prediction model was developed, and its overall performance was validated. A nomogram was created to facilitate the clinical use of the model. RESULTS: Of the 229 COPD patients analyzed, 77% of the patients did not experience exacerbation during the follow-up. The best subset in the training dataset revealed that lower forced expiratory volume, high scores on the MRC dyspnea scale, exacerbation history, and being on a combination therapy of LABA + ICS (long-acting beta-agonists + Inhaled Corticosteroids) or LAMA + LABA (Long-acting muscarinic receptor antagonists + long-acting beta-agonists) at baseline were associated with a higher rate of exacerbation. When validated, the area-under-curve (AUC) value was 0.75 for one or more exacerbations. The calibration was accurate (0.34 predicted exacerbations vs 0.28 observed exacerbations). CONCLUSION: Nomograms built from these models can assist clinicians in the decision-making process of COPD care.

Is Serum 25-Hydroxyvitamin D Level Associated with Severity of COVID-19? A Retrospective Study.

(1) Background: SARS-COV2 infection has a clinical spectrum ranging from asymptomatic infection to COVID-19 with acute respiratory distress syndrome (ARDS). Although vitamin D deficiency is often found in patients with ARDS, its role in COVID-19 is not clear. The aim of this study was to explore a possible association between serum 25-hydroxyvitamin D levels and the severity of COVID-19 in hospitalised patients. (2) Methods: In this retrospective observational study, we analysed data from 763 patients hospitalised for COVID-19 in 2020 and 2021. Patients were included in the study if serum 25-hydroxyvitamin D was assessed 30 days before or after hospital admission. Vitamin D deficiency was defined as <50 nmol/L (<20 ng/mL). The primary outcome was COVID-19 severity. (3) Results: The overall median serum 25-hydroxyvitamin D level was 54 nmol/L (IQR 35-76); 47% of the patients were vitamin D deficient. Most patients had mild to moderate COVID-19 and no differences were observed between vitamin D deficient and non-deficient patients (81% vs. 84% of patients, respectively p = 0.829). (4) Conclusion: No association was found between serum 25-hydroxyvitamin D levels and COVID-19 severity in this large observational study conducted over 2 years of the pandemic.

Predictors of Length of Stay, Rehospitalization and Mortality in Community-Acquired Pneumonia Patients: A Retrospective Cohort Study.

BACKGROUND: Community-acquired pneumonia (CAP) represents one of the leading causes of hospitalization and has a substantial impact on the financial burden of healthcare. The aim of this study was to identify factors associated with the length of hospital stay (LOHS), rehospitalization and mortality of patients admitted for CAP. METHODS: A retrospective cohort study was conducted with patients presenting to a Swiss public hospital between January 2019 and December 2019. Zero-truncated negative binomial and multivariable logistic regression analyses were performed to assess risk factors. RESULTS: A total of 300 patients were analyzed (median 78 years, IQR [67.56, 85.50] and 53% males) with an average LOHS of 7 days (IQR [5.00, 9.00]). Of the 300 patients, 31.6% (97/300) were re-hospitalized within 6 months, 2.7% (8/300) died within 30 days and 11.7% (35/300) died within 1 year. The results showed that sex (IRR = 0.877, 95% CI = 0.776-0.992, p-value = 0.036), age (IRR = 1.007, 95% CI = 1.002-1.012, p-value = 0.003), qSOFA score (IRR = 1.143, 95% CI = 1.049-1.246, p-value = 0.002) and atypical pneumonia (IRR = 1.357, 95% CI = 1.012-1.819, p-value = 0.04) were predictive of LOHS. Diabetes (OR = 2.149, 95% CI = 1.104-4.172, p-value = 0.024), a higher qSOFA score (OR = 1.958, 95% CI = 1.295-3.002, p-value = 0.002) and rehabilitation after discharge (OR = 2.222, 95% CI = 1.017-4.855, p-value = 0.044) were associated with a higher chance of being re-hospitalized within 6 months, whereas mortality within 30 days and within one year were both associated with older age (OR = 1.248, 95% CI = 1.056-1.562, p-value = 0.026 and OR = 1.073, 95% CI = 1.025-1.132, p-value = 0.005, respectively) and the presence of a cancer diagnosis (OR = 32.671, 95% CI = 4.787-369.1, p-value = 0.001 and OR = 4.408, 95% CI = 1.680-11.43, p-value = 0.002, respectively). CONCLUSION: This study identified routinely available predictors for LOHS, rehospitalization and mortality in patients with CAP, which may further advance our understanding of CAP and thereby improve patient management, discharge planning and hospital costs.

Effect of Single High Dose Vitamin D Substitution in Hospitalized COVID-19 Patients with Vitamin D Deficiency on Length of Hospital Stay.

Vitamin D and its role in the coronavirus-19 disease (COVID-19) pandemic has been controversially discussed, with inconclusive evidence about vitamin D3 (cholecalciferol) supplementation in COVID-19 patients. Vitamin D metabolites play an important role in the initiation of the immune response and can be an easily modifiable risk factor in 25-hydroxyvitamin D3 (25(OH)D3)-deficient patients. This is a multicenter, randomized, placebo-controlled double-blind trial to compare the effect of a single high dose of vitamin D3 followed by treatment as usual (TAU) of daily vitamin D3 daily until discharge versus placebo plus TAU in hospitalized patients with COVID-19 and 25(OH)D3-deficiency on length hospital stay. We included 40 patients per group and did not observe a significant difference in the median length of hospital stay (6 days in both groups, p = 0.920). We adjusted the length of stay for COVID-19 risk factors (ß = 0.44; 95% CI: -2.17-2.22), and center (ß = 0.74; 95% CI: -1.25-2.73). The subgroup analysis in patients with severe 25(OH)D3-deficiency (<25 nmol/L) showed a non-significant reduction in the median length of hospital stay in the intervention group (5.5 vs. 9 days, p = 0.299). The competing risk model with death did not reveal significant differences between the group in the length of stay (HR = 0.96, 95% CI 0.62-1.48, p = 0.850). Serum 25(OH)D3 level increased significantly in the intervention group (mean change in nmol/L; intervention: +26.35 vs. control: -2.73, p < 0.001). The intervention with 140,000 IU vitamin D3 + TAU did not significantly shorten the length of hospital stay but was effective and safe for the elevation of serum 25(OH)D3 levels.

Risk factors for hospital outcomes in pulmonary embolism: A retrospective cohort study.

Background: Pulmonary embolism (PE) is not only a life-threatening disease but also a public health issue with significant economic burden. The aim of the study was to identify factors-including the role of primary care-that predict length of hospital stay (LOHS), mortality and re-hospitalization within 6 months of patients admitted for PE. Method: A retrospective cohort study was conducted with patients presenting to a Swiss public hospital with PE diagnosed at the hospital between November 2018 and October 2020. Multivariable logistic and zero-truncated negative binomial regression analyses were performed to assess risk factors for mortality, re-hospitalization and LOHS. Primary care variables encompassed whether patients were sent by their general practitioner (GP) to the emergency department and whether a GP follow-up assessment after discharge was recommended. Further analyzed variables were pulmonary embolism severity index (PESI) score, laboratory values, comorbidities, and medical history. Results: A total of 248 patients were analyzed (median 73 years and 51.6% females). On average patients were hospitalized for 5 days (IQR 3-8). Altogether, 5.6% of these patients died in hospital, and 1.6% died within 30 days (all-cause mortality), 21.8% were re-hospitalized within 6 months. In addition to high PESI scores, we detected that, patients with an elevated serum troponin, as well as with diabetes had a significantly longer hospital stay. Significant risk factors for mortality were elevated NT-proBNP and PESI scores. Further, high PESI score and LOHS were associated with re-hospitalization within 6 months. PE patients who were sent to the emergency department by their GPs did not show improved outcomes. Follow-up with GPs did not have a significant effect on re-hospitalization. Conclusion: Defining the factors that are associated with LOHS in patients with PE has clinical implications and may help clinicians to allocate adequate resources in the management of these patients. Serum troponin and diabetes in addition to PESI score might be of prognostic use for LOHS. In this single-center cohort study, PESI score was not only a valid predictive tool for mortality but also for long-term outcomes such as re-hospitalization within 6 months.

Intermediate care in caring for dementia, the point of view of general practitioners: A key informant survey across Europe.

Background: Intermediate care is often defined as healthcare occurring somewhere between traditional primary (community) and secondary (hospital) care settings. High quality intermediate care is important in dementia, may prevent caregiver burnout and also lead to optimal care for people with dementia. However, very little is known about the point of intermediate care for persons with dementia in Europe. Research questions: What intermediate care services exist and how are they utilized in the care of people with dementia in Europe? Objective: This study aims at describing the point of view of General Practitioners on intermediate care services for people with dementia across Europe. Methods: Key informant survey was sent to GPs via a self-developed questionnaire with space for open ended comments. 16 European countries participated to this cross-sectional mixed method study. Given the volunteer nature of the study, no minimum sample size requirements were applied to participation. Convenience sampling technique was used to address variations due to regional variations and regulations within the same country. Descriptive analyses of all intermediate care facilities groups by countries were performed. Qualitative analyses approach was used for the optional-free text to exemplify and/or complete the reasons contained in the closed response categories. Results: The questionnaire was sent to 16 European countries. 583 questionnaires were analyzed. The responding physicians were 48 (± 11) years old on average and they had been in practice for an average of 18 (+ /11) years. The types of intermediate care considered were integrated at-home services, respite and relief services, day care centers and nursing homes. Their availability was considered very inhomogeneous by the majority of respondents. The main benefits of intermediate care cited were better medical care for the patient (78%), better quality of life for the caregiver (67%), prevention of the caregiver burden (73%) and a break for the caregiver (59%). The reported difficulties were: accessing these facilities due to limited financial support (76%) and cumbersome administrative procedures (67%). Many other facets of our findings were captured in the qualitative themes that emerged. Conclusion: Intermediate care in Europe is diverse and heterogeneous. Major concerns of GPs are about the cost issues and the cumbersome administrative procedures to access them.

Inhaled aviptadil for the possible treatment of COVID-19 in patients at high risk for ARDS: study protocol for a randomized, placebo-controlled, and multicenter trial.

BACKGROUND: Despite the fast establishment of new therapeutic agents in the management of COVID-19 and large-scale vaccination campaigns since the beginning of the SARS-CoV-2 pandemic in early 2020, severe disease courses still represent a threat, especially to patients with risk factors. This indicates the need for alternative strategies to prevent respiratory complications like acute respiratory distress syndrome (ARDS) associated with COVID-19. Aviptadil, a synthetic form of human vasoactive intestinal peptide, might be beneficial for COVID-19 patients at high risk of developing ARDS because of its ability to influence the regulation of exaggerated pro-inflammatory proteins and orchestrate the lung homeostasis. Aviptadil has recently been shown to considerably improve the prognosis of ARDS in COVID-19 when applied intravenously. An inhaled application of aviptadil has the advantages of achieving a higher concentration in the lung tissue, fast onset of activity, avoiding the hepatic first-pass metabolism, and the reduction of adverse effects. The overall objective of this project is to assess the efficacy and safety of inhaled aviptadil in patients hospitalized for COVID-19 at high risk of developing ARDS. METHODS: This multicenter, placebo-controlled, double-blinded, randomized trial with 132 adult patients hospitalized for COVID-19 and at high risk for ARDS (adapted early acute lung injury score ≥ 2 points) is conducted in five public hospitals in Europe. Key exclusion criteria are mechanical ventilation at baseline, need for intensive care at baseline, and severe hemodynamic instability. Patients are randomly allocated to either inhale 67 µg aviptadil or normal saline (three times a day for 10 days), in addition to standard care, stratified by center. The primary endpoint is time from hospitalization to clinical improvement, defined as either hospital discharge, or improvement of at least two levels on the nine-level scale for clinical status suggested by the World Health Organization. DISCUSSION: Treatment strategies for COVID-19 are still limited. In the context of upcoming new variants of SARS-CoV-2 and possible inefficacy of the available vaccines and antibody therapies, the investigation of alternative therapy options plays a crucial role in decreasing associated mortality and improving prognosis. Due to its unique immunomodulating properties also targeting the SARS-CoV-2 pathways, inhaled aviptadil may have the potential to prevent ARDS in COVID-19.

Measuring workload of Swiss general practice: a five-yearly questionnaire-based survey on general practitioners' self-reported working activities (2005-2020).

INTRODUCTION: General practitioners (GPs) play a key role in the delivery of health care in Switzerland. Assessing GPs' workload over time is essential to meet the population's health service demand and for future health care planning. METHODS: The study involved four questionnaire-based cross-sectional studies among a representative sample of Swiss GPs on a five-yearly basis since 2005. Data on GPs' self-estimated workload and practice administration (face-to-face consultations, house calls, nursing home visits and clinical administrative work) were analysed in hours per week (h/week) or full-time equivalents (FTE; 100% = 55 h/week). RESULTS: The mean age of GPs (n = 2,037) in 2020 was 54.9 years, significantly higher than in 2005 (51.4 years, p <0.001, n = 1,780). The proportion of female GPs increased gradually from 16.5% in 2005 to 36.2% in 2020 (p <0.001). The GPs' workload significantly decreased over the last 15 years from 50.2 h/week to 43.4 h/week or from 90.9% FTE in 2005 to 78.9% FTE in 2020 (p <0.001). The decreased average workload across years was less pronounced in women (-4.4% FTE) than in men (-9.0% FTE, p = 0.015). Across all survey years, women worked on average 12.7 h/week or 23.2% FTE less than men (p <0.001). The time spent with patients gradually decreased, whereas the amount of time spent on clinical administrative work remained stable since 2005 (9 h/week). In 2020, GPs were working more frequently in group practices compared to 2005 (45.0% vs. 12.4%, p <0.001). CONCLUSION: This study demonstrates a decrease in GPs' overall workload from 2005 to 2020, indicating that the "new" generation of GPs prefers to work part-time. This decrease is at the expense of direct face-to-face encounters with patients. Over the last 15 years, a clear trend exists towards more women in the Swiss general practice, persisting over-ageing of GPs, replacement of single-handed practices by group practices, and increasing burden of administrative tasks, a risk factor for burnout and reduced job satisfaction. To maintain an efficient healthcare system in the future, substantial efforts are crucial to provide a positive and motivating insight into general practice to pre- and postgraduate students and improve the operational working conditions of GPs.

High-dose vitamin D substitution in patients with COVID-19: study protocol for a randomized, double-blind, placebo-controlled, multi-center study-VitCov Trial.

BACKGROUND: The coronavirus disease 19 (COVID-19) pandemic has caused millions of deaths, and new treatments are urgently needed. Factors associated with a worse COVID-19 prognosis include old age (> 65 years), ethnicity, male sex, obesity, and people with comorbidities. Furthermore, vitamin D deficiency was reported as a predictor of poor prognosis in patients with acute respiratory failure due to COVID-19. According to a recent clinical case series, vitamin D deficiency is a modifiable risk factor, which has the prospect of reducing hospital stay, intensive care, and fatal outcomes. Vitamin D has potent immunomodulatory properties, and its supplementation might improve important outcomes in critically ill and vitamin D-deficient COVID-19 patients. Despite the evidence that supports an association between vitamin D deficiency and COVID-19 severity, there is uncertainty about the direct link. Therefore, the aim of the trial is to assess if high-dose vitamin D supplementation has a therapeutic effect in vitamin D-deficient patients with COVID-19. METHODS: As the trial design, a randomized, placebo-controlled, double-blind, multi-center approach was chosen to compare a high single dose of vitamin D (140,000 IU) followed by treatment as usual (TAU) (VitD + TAU) with treatment as usual only (placebo + TAU) in patients with COVID-19 and vitamin D deficiency. DISCUSSION: Vitamin D substitution in patients with COVID-19 and vitamin D deficiency should be investigated for efficacy and safety. The study aim is to test the hypothesis that patients with vitamin D deficiency suffering from COVID-19 treated under standardized conditions in hospital will recover faster when additionally treated with high-dose vitamin D supplementation. Latest studies suggest that vitamin D supplementation in patients with COVID-19 is highly recommended to positively influence the course of the disease. With this randomized controlled trial, a contribution to new treatment guidelines shall be made. TRIAL REGISTRATION: ClinicalTrials.gov NCT04525820 and SNCTP 2020-01401.

COVID-19 Symptoms and Testing in the Swiss General Population: A Cross-Sectional Survey.

We estimated the incidence of COVID-19-compatible symptoms, COVID-19 testing, and GP consultations during the first lockdown period in Switzerland (March-April 2020). A representative sample of the adult Swiss population completed an online survey. Of the 1022 respondents, 74 % reported at least one symptom, 5 % were tested for COVID-19, and 8 % contacted their GP regarding COVID-19. Testing was significantly associated with reduced sense of taste/smell, fever, cough with expectoration, and fatigue. Respondents at risk for severe COVID-19 were less likely to be tested but were five times more likely to contact their GP than those not at risk. We highlight the need to involve the appropriate health care setting to reach the vulnerable population when testing capacities are restricted (e.g. GPs).

Prediction of Acute COPD Exacerbation in the Swiss Multicenter COPD Cohort Study (TOPDOCS) by Clinical Parameters, Medication Use, and Immunological Biomarkers.

BACKGROUND AND OBJECTIVE: Whether immunological biomarkers combined with clinical characteristics measured during an exacerbation-free period are predictive of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) frequency and severity is unknown. METHOD: We measured immunological biomarkers and clinical characteristics in 271 stable chronic obstructive pulmonary disease (COPD) patients (67% male, mean age 63 years) from "The Obstructive Pulmonary Disease Outcomes Cohort of Switzerland" cohort on a single occasion. One-year follow-up data were available for 178 patients. Variables independently associated with AECOPD frequency and severity were identified by multivariable regression analyses. Receiver operating characteristic analysis was used to obtain optimal cutoff levels and measure the area under the curve (AUC) in order to assess if baseline data can be used to predict future AECOPD. RESULTS: Higher number of COPD medications (adjusted incident rate ratio [aIRR] 1.17) and platelet count (aIRR 1.03), and lower FEV1% predicted (aIRR 0.84) and IgG2 (aIRR 0.84) were independently associated with AECOPD frequency in the year before baseline. Optimal cutoff levels for experiencing frequent (>1) AECOPD were ≥3 COPD medications (AUC = 0.72), FEV1 ≤40% predicted (AUC = 0.72), and IgG2 ≤2.6 g/L (AUC = 0.64). The performance of a model using clinical and biomarker parameters to predict future, frequent AECOPD events in the same patients was fair (AUC = 0.78) but not superior to a model using only clinical parameters (AUC = 0.79). The IFN-lambda rs8099917GG-genotype was more prevalent in patients who had severe AECOPD. CONCLUSIONS: Clinical and biomarker parameters assessed at a single point in time correlated with the frequency of AECOPD events during the year before and the year after assessment. However, only clinical parameters had fair discriminatory power in identifying patients likely to experience frequent AECOPD.

Adding a liquid test meal to a standardized lactulose hydrogen breath test significantly influences abdominal symptom generation and hydrogen values.

OBJECTIVE: While single sugar tests are controversially discussed, combination tests with meals are gaining more attention. The aim of this study was to analyze the impact of adding a test meal to lactulose hydrogen breath tests (LHBT) on hydrogen values and abdominal symptoms in patients with functional gastrointestinal disorders (FGIDs). METHODS: Data of 81 FGID patients between 2014-2018 were analyzed. Patients underwent LHBT with 30 g lactulose + 300 mL water and a nutrient challenge test (NCT) including 400 mL liquid test meal + 30 g lactulose. To statistically assess the effect of a test meal on abdominal symptoms and H2, mixed-effect models were used. RESULTS: Adding a test meal to LHBT showed a significant increase in nausea [odds ratio (OR) 1.4; 95% confidence interval (CI), 1.1-1.7], decrease in abdominal pain (OR 0.7; 95% CI, 0.6-0.9), borborygmi (OR 0.5; 95% CI, 0.4-0.6), diarrhea (OR 0.4; 95% CI, 0.3-0.6), and H2 production (estimate -5.3, SE 0.7, P < 0.001). The effect on bloating was only significant in functional dyspepsia, irritable bowel syndrome-functional dyspepsia mixed type and functional abdominal pain/bloating (OR 0.1; 95% CI, 0.0-0.2; OR 1.7; 95% CI, 1.2-2.3 resp OR 4.4; 95% CI, 1.8-10.6). CONCLUSIONS: Significant effects on abdominal symptoms and H2 production by adding a test meal to LHBT in FGID patients are shown. Increased occurrence of nausea may be caused by gastric/duodenal hypersensitivity; decreased H2, diarrhea and borborygmi by slower and more physiologic gastric emptying resulting in later arrival of the test substance in the bowel. We recommend NCTs instead of LHBT to more physiologically represent FGID patients' meal-induced burden.

Arbeitszufriedenheit und Stresserleben der jungen Hausärztinnen und Hausärzte ­ Subanalyse aus der Workforce-Studie Schweizer Hausärzteschaft 2020.

This questionnaire-based cross-sectional analysis with 2037 Swiss general practitioners (GPs) focused on young GPs (≤40 years) and investigated which preconditions would allow them high satisfaction and low stress levels in their work. Young GPs (n = 206) are more often female (57 %, p <0.001), 46 % are employed, have a lower workload (38.2 vs. 44.0 hours per week, p <0.001) and plan significantly more often consultations of 30 minutes (p = 0.006) than older colleagues. Under 40-year-old GPs were more satisfied with their work situation (p = 0.046), but had a higher stress level (p = 0.01) compared to GPs >40 years of age. Administrative tasks tend to increase stress levels (p = 0.054). Knowing the problems of the young GP workforce is essential to securing the next generation of physicians.

The effect of COVID-19 on mental well-being in Switzerland: a cross-sectional survey of the adult Swiss general population.

BACKGROUND: In addition to the threat of the COVID-19 pandemic to physical health, mental health is challenged by the emotional response to the situation and the official measures taken to stop the pandemic. This study aimed to assess the prevalence of impaired mental well-being due to COVID-19 and explore associated factors. METHODS: The study was an observational, population-based, nationwide, cross-sectional online survey of a representative sample of the general Swiss population performed between March and April 2020. Participants reported on mental well-being, self-isolation/quarantine, their risk for developing severe COVID-19, and their work situation. Multivariable logistic regression analyses assessed risk factors for impaired mental well-being due to the pandemic. RESULTS: Data from 1022 individuals were analysed. The median age was 44 years (range 18 to 78) and 49% were women. A third of respondents reported that the COVID-19 pandemic impaired their mental well-being and almost half reported specific mental health concerns. Impaired mental well-being was associated with having health problems (OR = 1.88, 95% CI: 1.29-2.74, vs no problems), being or living with someone at risk for severe COVID-19 (OR = 1.38, 95% CI: 1-1.9,), smoking (OR = 1.8, 95% CI: 1.24-2.61), living in urban residential environments (OR = 1.62, 95% CI: 1.13-2.32, vs rural), not being able to work due to closed workplace (OR = 1.66, 95% CI: 1.04-2.67), aged between 18 and 29 years old (OR = 1.99, 95% CI: 1.32-3.01, vs 45 to 59 years old), and living in a single household (living with someone, OR = 0.65, 95% CI: 0.44-0.97,vs single household). Overall, the most significant covariates of impaired mental well-being were specific mental health concerns: feeling depressed (OR = 7.21, 95% CI: 4.5-11.55), feeling less pleasure in doing things than before (OR = 6.28, 95% CI: 4.1-9.62), feeling anxious (OR = 6.13, 95% CI: 3.91-9.59) and feeling lonely (OR = 4.08, 95% CI: 2.53-6.58). CONCLUSION: Impaired mental well-being can carry long-term consequences. We encourage policymakers to implement strategies to promote mental health during this pandemic situation. Special attention should be addressed to the youngest, those at risk for severe COVID-19 and those with government-imposed work restrictions.

Expectations about check-up examinations among Swiss residents: A nationwide population-based cross-sectional survey.

INTRODUCTION: General health check-up examinations in asymptomatic adults have not been shown to be beneficial. Instead, opportunistic prevention during regular primary care consultations is most cost-effective and recommended. The study aimed to elucidate the expectations about check-ups of the general Swiss population. METHODS: A nationwide cross-sectional telephone survey was conducted in a representative sample of the population, stratified by sex, age, and language in November 2019. RESULTS: Data of 1077 respondents were analysed. Mean age was 45 years (range 18 to 89), and 51% were female. Overall, 40% of respondents expected to have check-up examinations (yearly: 41.6%), and 42% expected opportunistic prevention. Most expected check-up interventions were sex-specific such as mammography (89% of women), Pap smear test (89% of women), and blood test of prostate-specific antigen (81% of men). The least favoured ones related to counselling (tobacco: 27%; alcohol abuse: 29%). Most significant predictors of positive check-up expectations were being male (OR = 1.45, CI: 1.02-2.05 P = 0.04)), age between 45 and 59 years old (OR = 2.03, CI: 1.27-3.23, P = 0.003 vs. 18 to 29 years), having a degree from professional (OR = 1.73, 95% CIs: 1.11-2.69, P 0.015) or, middle school (OR = 1.99, 95% CIs:1.04-3.78, P = 0.037) or university (OR = 1.66, 95% CIs: 1.06-2.61, P< 0.001, vs. secondary school) and the more importance attributed to regularly checking one's health (OR = 2.12, 95% CIs: 1.70-2.36, P < 0.001). CONCLUSIONS: Almost half of the population expected to have mostly yearly check-up examinations in addition to regular care, which is in contradiction to recommendations. This behaviour impacts the rational use of health care resources and must be considered by physicians and given the active role of patients in the health care system.

Better response to low FODMAP diet in disorders of gut-brain interaction patients with pronounced hydrogen response to a nutrient challenge test.

BACKGROUND AND AIM: Previous studies have shown a reduction of gastrointestinal symptoms in irritable bowel syndrome (IBS) patients following a low FODMAP diet (LFD). It remains unknown which disorders of gut-brain interaction (DGBI) patients would benefit most from LFD. We aimed to analyze LFD response regarding a preceding nutrient challenge test (NCT). METHODS: Data of 110 consecutive DGBI patients undergoing NCT and LFD between August 2015 and August 2018 were analyzed retrospectively. LFD response was assessed by changes in IBS Symptom Severity Score (IBS-SSS). In mixed-effects linear regression models, the impact of hydrogen values and abdominal symptoms during NCT, performed with 30-g lactulose and 400-mL liquid test meal, on IBS-SSS changes were analyzed. RESULTS: Low FODMAP diet induced a significant IBS-SSS reduction of 78 points (95% confidence interval [CI] 50-96; P < 0.001). Patients with higher NCT-induced hydrogen increase during proximal intestinal transit had a significantly better LFD response (-66 IBS-SSS reduction per 10-ppm hydrogen increase, 95% CI -129 to -4, P = 0.045). Additionally, the higher the NCT-induced maximum hydrogen increase during mid-distal and distal intestinal transit, the better are the responses to LFD (-6 IBS-SSS per 10-ppm maximum delta hydrogen, 95% CI -11 to -1, P = 0.040). There was no association of LFD response with abdominal symptom generation during NCT. CONCLUSIONS: Our study is the first one analyzing and demonstrating significant associations between NCT results and LFD response. These findings are of high clinical importance, as they identify a subgroup of DGBI patients that may profit most from a restrictive LFD as first-line therapy.

The use of health care during the SARS-CoV-2 pandemic: repeated cross-sectional survey of the adult Swiss general population.

BACKGROUND: The distribution of health care resources during a pandemic is challenging. The aim of the study was to describe the use of health care in a representative sample of the Swiss population during the SARS-CoV-2 pandemic in 2020, and to compare it to data from a survey conducted in 2018. METHODS: We conducted an observational, population-based, nationwide, repeated cross-sectional survey of the adult Swiss general population in 2018 and in March and April 2020 during the first wave of the SARS-CoV-2 pandemic. Recruitment and data acquisition was conducted by the Link Institute in Lucerne in representative samples of Swiss citizens in 2020 and in 2018. Variables of interest were estimates of health problems, health seeking behaviour, medication and health care use in the population. RESULTS: In total, we included data of 1980 individuals (in 2018 N = 958 and in 2020 N = 1022). Across both rounds of data collection the median age was 46 years (range = 18-79 years) and 50% were women. Per 1000 adults, half had at least one symptom and a quarter sought medical advice across both surveys. The most frequently consulted health providers in 2020 were general practitioners (GP) (180/1000), specialist physicians (41/1000), pharmacies (38/1000), the internet (26/1000) and accident and emergency units (25/1000). Compared to 2018, we noted a significant increase in the use of health providers during the pandemic, which was independent of demographic variables for the following health care providers: use of internet (OR = 9.8), pharmacy (OR = 2.64), accident and emergency units (OR = 2.54), and a significant decrease in the number of people who consulted specialist physicians (OR = 0.46). Overall, 76/1000 contacted their GP in relation to COVID-19. CONCLUSIONS: Compared to 2018, GPs remained the most important source of medical advice for the population during the first wave of the COVID-19 pandemic in Switzerland. While the self-appraisal of health problems and of the need for medical advice remained constant, individuals seemed to change their provider choice during the pandemic, with an increased utilisation of accident and emergency units and pharmacies, which represent easily accessible and low-threshold medical services.

[Geriatric Psychiatry in Nursing Homes in the Canton Basel-Stadt - The View of General Practitioners]. / Die hausärztliche gerontopsychiatrische Versorgung in Stadtbasler Alters- und Pflegeheimen.

Geriatric Psychiatry in Nursing Homes in the Canton Basel-Stadt - The View of General Practitioners Abstract. Background: This cross-sectional study intends to examine the potential need for an outpatient geronto-psychiatric service and evaluates GPs' views of the frequency of psychiatric symptoms among residents of nursing homes in the canton of Basel-Stadt, Switzerland. Results: Nine out of ten (89 %) see a need for a geronto-psychiatric service. Two thirds (58,9 %) of them prefer a service available during office hours. GPs estimate that 63 % of their nursing home residents suffer from psychiatric symptoms (dementia in 60 %, depression in 23 %, sleep disorders in 11 %). Antipsychotics are prescribed most often (in 50,6 %). Discussion: GPs in the canton of Basel-Stadt see a need for an outpatient geronto-psychiatric service. Psychiatric symptoms are common among residents of nursing homes.

[Early recognition or screening of dementia in general practice]. / Früherkennung oder Screening von Demenzerkrankungen in der hausärztlichen Praxis.

Early recognition or screening of dementia in general practice Abstract. General practitioners play a key role in timely dementia diagnosis. In view that there are currently no drugs to prevent the progression of dementia or are effective in patients with mild cognitive impairment, a general screening of older people to recognize pre-symptomatic stages of dementia is not recommended. Crucial for a timely diagnosis is the GP's perception of warning signs, so-called "red flags". If the patients, family members, authorities or even the GP notice even discreet signs of a possible early dementia, a neuropsychological and medical evaluation should be initiated. Personal history, history by informant, a physical examination, supplemented by a GP's psychiatric evaluation and ideally the careful assessment with the MoCA form the basis of a preliminary clarification in general practice. If dementia is suspected, this clarification should be supplemented by an in-depth laboratory examination and, if applicable, neuroimaging before the patient is referred, depending on the findings, to a memory clinic or a consultant specialist to confirm the diagnosis and if appropriate initiate pharmacological and non-pharmacological therapies.

Risk factors for peritonsillar abscess in streptococcus A-negative tonsillitis: a case control study.

AIMS: The Centor criteria and the FeverPAIN score are recommended for guiding antibiotic prescription for tonsillitis, but they are not validated for this purpose. We aimed to identify risk factors for peritonsillar abscess in group A haemolytic streptococcus-negative tonsillitis and to test the performance of clinical scores and laboratory tests. METHODS: In a retrospective case-control study at two regional hospitals from January 2015 to June 2018, we identified all cases of peritonsillar abscess and used propensity score matching utilising age and gender to select two controls per case from all patients who had a rapid group A haemolytic streptococcus antigen test in the emergency department. Exclusion criteria were age <18 years, documented refusal and a positive antigen test. We abstracted patient history, physical examination and results of laboratory testing. Logistic regression analysis was used to identify risk factors. RESULTS: We included 141 cases of peritonsillar abscess, matched with 282 controls. Higher Centor score, C-reactive protein and white blood cell count were significantly associated with peritonsillar abscess, but had a low performance for predicting the latter (area under the receiver operator characteristic curve [ROC AUC] 0.76). The FeverPAIN score was not associated with peritonsillar abscess (ROC AUC 0.51). In the multivariable analysis, difficulty swallowing (odds ratio [OR] 18.4, 95% confidence interval [CI] 6.58–51.2), dyspnoea (OR 10.2, 95% CI 1.18–89.0), tonsillar swelling (OR 4.21, 95% CI 1.39–12.7) and unilateral signs and symptoms (OR 146, 95% CI 40.9–522) were risk factors of peritonsillar abscess. CONCLUSION: The Centor criteria, as well as C-reactive protein and white blood cell count, have a low discriminatory performance, and the FeverPAIN score is not useful in identifying patients at risk for peritonsillar abscess in group A haemolytic streptococcus-negative tonsillitis. To guide a rational antibiotic prescription, new decision tools need to be developed. These might include items such as difficulty swallowing, dyspnoea, tonsillar swelling and unilaterality.
