The medical field causes significant environmental impact. Reduction of the primary care practice carbon footprint could contribute to decreasing global carbon emissions. This study aims to quantify ...the average carbon footprint of a primary care consultation, describe differences between primary care practices (best, worst and average performing) in western Switzerland and identify opportunities for mitigation.
We conducted a retrospective carbon footprint analysis of ten private practices over the year 2018. We used life-cycle analysis to estimate carbon emissions of each sector, from manufacture to disposal, expressing results as CO
equivalents per average consultation and practice. We then modelled an average and theoretical best- case and worst-case practices. Collected data included invoices, medical and furniture inventories, heating and power supply, staff and patient transport, laboratory analyses (in/out-house) waste quantities and management costs.
An average medical consultation generated 4.8 kg of CO
eq and overall, an average practice produced 30 tons of CO
eq per year, with 45.7% for staff and patient transport and 29.8% for heating. Medical consumables produced 5.5% of CO
eq emissions, while in-house laboratory and X-rays contributed less than 1% each. Emergency analyses requiring courier transport caused 5.8% of all emissions. Support activities generated 82.6% of the total CO
eq. Simulation of best- and worst-case scenarios resulted in a ten-fold variation in CO
eq emissions.
Optimizing structural and organisational aspects of practice work could have a major impact on the carbon footprint of primary care practices without large-scale changes in medical activities.
Background: Buruli ulcer (BU) is a cutaneous infectious disease caused by Mycobacterium ulcerans. In this prospective study, we aim to clarify the main histopathological features of cutaneous BU ...based on 4-mm skin punch biopsies and to evaluate the diagnostic value of this method. Methods: Between 2011 and 2013, a prospective study was conducted in Cameroon. Dry swabs from ulcerative lesions and fine-needle aspirates of nonulcerative lesions were examined for Ziehl-Neelsen (ZN) staining, followed by PCR targeting IS2404 and culture. Two 4-mm punch biopsies were performed in the center and in the periphery of each lesion. Results: The 364 patients included in the study had 422 lesions (381 were ulcerative and 357 lesions were biopsied). Among the 99 ulcerated lesions with a final diagnosis of BU, histological features for BU were fulfilled in 32 lesions. 32/32 showed subcutaneous necrosis with a neutrophilic inflammatory infiltrate. 26/32 presented alcohol-resistant bacilli confirmed by ZN stain on histology. Conclusion: Punch biopsies help in establishing the correct diagnosis of BU and also in the differential diagnosis of chronic ulcers. The main histological feature for BU is diffuse coagulative necrosis of subcutaneous tissue, with acid-fast bacilli detected by ZN stain.
Clinical diagnosis of Buruli ulcer (BU) due to Mycobacterium ulcerans can be challenging. We aimed to specify the differential diagnosis of skin lesions in a BU endemic area.
We conducted a ...prospective diagnostic study in Akonolinga, Cameroon. Patients presenting with a skin ulcer suspect of BU were included. M. ulcerans was detected using swabs for Ziehl-Neelsen staining, PCR and culture. Skin punch biopsies were taken and reviewed by two histopathologists. Photographs of the lesions were taken and independently reviewed by two dermatologists. Final diagnosis was based on consensus, combining the results of laboratory tests and expert opinion.
Between October 2011 and December 2013, 327 patients with ulcerative lesions were included. Median age was 37 years (0 to 87), 65% were males, and 19% HIV-positive. BU was considered the final diagnosis for 27% of the lesions, 85% of which had at least one positive laboratory test. Differential diagnoses were vascular lesions (22%), bacterial infections (21%), post-traumatic (8%), fistulated osteomyelitis (6%), neoplasia (5%), inflammatory lesions (3%), hemopathies and other systemic diseases (2%) and others (2%). The proportion of BU was similar between HIV-positive and HIV-negative patients (27.0% vs. 26.5%; p = 0.940). Half of children below 15 years of age were diagnosed with BU, compared to 26.8% and 13.9% among individuals 15 to 44 years of age and above, respectively (chi2 p<0.001). Children had more superficial bacterial infections (24.3%) and osteomyelitis (11.4%).
We described differential diagnosis of skin lesions in a BU endemic area, stratifying results by age and HIV-status.
Although physicians' home visits are highly valued by patients, and are among the measures that contribute to maintaining elderly patients at home, their number is decreasing worldwide. We aimed to ...describe the trends in home visits made by general practitioners (GPs) in the canton of Vaud in Switzerland between 2006 and 2015, and to explore their associated characteristics.
We retrospectively analysed billing data from family physicians (internists, generalists and practicing physicians) transmitted to the cantonal trust centre between 2006 and 2015. We explored physician and patient characteristics, first over the entire 10-year study period and then averaged by year. To explore factors associated with the number of home visits, we fitted a mixed effect negative binomial regression of the annual number of home visits per physician.
Over ten years, 631 physicians billed a total of 451,634 home visits, of which 19.8% (n = 89,966) were emergency visits, and 9.7% (n = 43,915) were over the weekend. Home visits represented 2.5% of all consultations. Although the average annual number of physicians doing home visits remained stable at around 400, the mean annual number of visits per physician decreased from 125 in 2006 to 75 in 2015, resulting in a 40% decline in the absolute number of visits. Male physicians undertook more home visits than their female counterparts did, although the difference diminished over time. Visits to elderly patients (65+) represented 84.2% of the home visits.
Although most physicians in the canton of Vaud continue to visit patients at home, the overall number of home visits is declining. Most home visits consist of routine visits to elderly patients. Physicians' gender, age and specialty are associated with the number of home visits. In the rapidly evolving context of an ageing population and the development of home care, physicians' role in home care provision should be revised, taking into account patient expectations and current health system constraints.
In the context of an aging population, homecare visits by family physicians may contribute to maintaining older patients at home; however, home visits by family physicians have decreased in number in ...the last decade with the emergence of homecare-oriented healthcare services. We aimed to describe the diversity of activities and evolution over time of home visits by Swiss family physicians.
This was a retrospective observational descriptive study. We used billing data collected by the cantonal trust centre for home visits made by family physicians of the canton of Vaud, Switzerland from 2006 to 2015. We separated billed items into specific categories, including the Tarmed catalogue (Swiss pricing system for medical services), laboratory catalogue, medications, medical material and vaccines. We compared billing patterns between emergency and routine visits. We used discrete mixture models to identify cluster classes of visits, and compare their characteristics.
From 2006 to 2015, Vaud family physicians made 451,634 home visits for which they billed a median of 5 items per visit (range 2-95). Most home visits (65%, 293,713) were routine visits consisting of consultation time without additional investigation. We identified four cluster classes of visits comprising routine visits, routine visits with laboratory tests, emergency visits during the day and emergency visits during the night. Routine visits were the main cluster class while emergency home visits were rare.
Family physician home visits are mainly routine visits without additional investigation. Thus, we wonder if a part of this activity could be delegated to other healthcare professionals.
During the COVID pandemic, data collected in family medicine were scarce. The COVID-FM project aimed to monitor trends of COVID-related activity in family medicine practices of the canton of Vaud, ...Switzerland, during the year 2021.
Practitioners were invited to join an
sentinel surveillance system. Online data collection was based on daily activity reports and monthly questionnaires. Participants categorized daily counts of consultations and phone calls into predefined categories. Data were reported and discussed on a weekly basis with public health authorities.
On the target of 50 physicians, 37 general physicians from 32 practices finally constituted the COVID-FM sentinel network, contributing to 901 practice-weeks of surveillance in family medicine and 604 in paediatrics. In paediatrics, COVID-related activity corresponded mostly to COVID-19 diagnostic consultations (2911/25990 face-to-face consultations = 11.2%) while in family medicine, other COVID-related topics-such as questions on vaccination-predominated (4143/42221 = 9.8%).
COVID-related consultations constituted an important part of primary care practices' activity in 2021. Monitoring COVID-related activity in primary care provided health authorities with valuable information to guide public health action.
Objectives: This study investigates gender and sex disparities in COVID-19 epidemiology in the Canton of Vaud, Switzerland, focusing on the interplay with socioeconomic position (SEP) and age. ...Methods: We analyzed COVID-19 surveillance data from March 2020 to June 2021, using an intersectional approach. Negative binomial regression models assessed disparities between women and men, across SEP quintiles and age groups, in testing, positivity, hospitalizations, ICU admissions, and mortality (Incidence Rate Ratios IRR, with 95% Confidence Intervals CI). Results: Women had higher testing and positivity rates than men, while men experienced more hospitalizations, ICU admissions, and deaths. The higher positivity in women under 50 was mitigated when accounting for their higher testing rates. Within SEP quintiles, gender/sex differences in testing and positivity were not significant. In the lowest quintile, women’s mortality risk was 68% lower (Q1: IRR 0.32, CI 0.20–0.52), with decreasing disparities with increasing SEP quintiles (Q5: IRR 0.66, CI 0.41–1.06). Conclusion: Our findings underscore the complex epidemiological patterns of COVID-19, shaped by the interactions of gender/sex, SEP, and age, highlighting the need for intersectional perspectives in both epidemiological research and public health strategy development.
Access to laboratory diagnosis can be a challenge for individuals suspected of Buruli Ulcer (BU). Our objective was to develop a clinical score to assist clinicians working in resource-limited ...settings for BU diagnosis.
Between 2011 and 2013, individuals presenting at Akonolinga District Hospital, Cameroon, were enrolled consecutively. Clinical data were collected prospectively. Based on a latent class model using laboratory test results (ZN, PCR, culture), patients were categorized into high, or low BU likelihood. Variables associated with a high BU likelihood in a multivariate logistic model were included in the Buruli score. Score cut-offs were chosen based on calculated predictive values. Of 325 patients with an ulcerative lesion, 51 (15.7%) had a high BU likelihood. The variables identified for the Buruli score were: characteristic smell (+3 points), yellow color (+2), female gender (+2), undermining (+1), green color (+1), lesion hyposensitivity (+1), pain at rest (-1), size >5cm (-1), locoregional adenopathy (-2), age above 20 up to 40 years (-3), or above 40 (-5). This score had AUC of 0.86 (95%CI 0.82-0.89), indicating good discrimination between infected and non-infected individuals. The cut-off to reasonably exclude BU was set at scores <0 (NPV 96.5%; 95%CI 93.0-98.6). The treatment threshold was set at a cut-off ≥4 (PPV 69.0%; 95%CI 49.2-84.7). Patients with intermediate BU probability needed to be tested by PCR.
We developed a decisional algorithm based on a clinical score assessing BU probability. The Buruli score still requires further validation before it can be recommended for wide use.
We aimed to assess how often and for what reasons general practitioners (GPs) consider older drivers medically unfit to drive.
All GPs certified to carry out fitness-to-drive assessments in Geneva ...(medical assessors, n = 69), as well as a random sample of 500 GPs practising in Vaud, Neuchatel and Jura, were asked to complete a questionnaire about the mean number of assessments per week, the number of negative decisions in the previous year and the main reason for the most recent negative decision.
Completed questionnaires were returned by 268 respondents (45 medical assessors and 223 other GPs, participation rate: 47%). The mean proportion of drivers with a negative decision was 2.2% (standard deviation SD 3.3). The proportion was slightly lower among medical assessors (1.1%, SD 1.3) compared to other GPs (2.3%, SD 3.3, p <0.001). The main reasons for being considered medically unfit to drive were cognitive (64%) and visual acuity impairments (18%).
GPs in this survey reported considering approximately 2% of older drivers as medically unfit to drive, mainly because of cognitive and visual acuity impairments. Further research should identify how GPs decide if older drivers are fit or unfit, and assess the effectiveness of medical screening in reducing car crashes involving older drivers.
In general practice, the diagnosis of dementia is often delayed. Therefore, the Swiss National Dementia Strategy 2014 concluded that action was needed to improve patient care. Little is known about ...GPs' confidence in and approach to the diagnosis, disclosure and post-diagnostic management of individuals with dementia in Switzerland. The aim of this survey is to assess these elements of dementia care and GPs' views on the adequacy of health care services regarding dementia.
Cross-sectional postal survey in Switzerland in 2017 supported by all academic institutes of general practice in Swiss universities. Members of the Swiss Association of General Practitioners (n = 4460) were asked to participate in the survey. In addition to the GPs' demographic characteristics, the survey addressed the following issues: GPs' views on the adequacy of health care services, clinical approach and confidence in the management of dementia.
The survey response rate was 21%. The majority of GPs (64%) felt confident diagnosing dementia, but not in patients with a migration background (15%). For neuropsychological testing, three-quarters of GPs collaborated with memory clinics and were satisfied with the access to diagnostic services. At the time of first diagnosis, 62% of GPs diagnosed the majority of their patients with a mild stage of dementia, and 31% with a mild cognitive impairment. The most frequent actions taken by GPs after the diagnosis of mild dementia were giving advice to relatives (71%), testing fitness-to-drive (66%) and minimising cardiovascular risk factors (63%). While 65% of GPs felt confident taking care of patients with dementia, fewer (53%) felt confident in pharmacological treatment, coping with suicidal ideation (44%) or caring for patients with a migration background (16%). Half of GPs preferred to delegate the assessment of fitness-to-drive to an official authority. One in four GPs was not satisfied with the local provision of care and support facilities for patients with dementia.
Overall, GPs reported confidence in establishing a diagnosis of dementia and sufficient access to diagnostic services. Post-diagnostic management primarily focused on counselling and harm reduction rather than pharmacological treatment. Future educational support for GPs should be developed, concentrating on coping with their patients' suicidal ideation and caring for patients with a migration background.
