Syphilis in pregnant women and congenital syphilis from 2012 to 2021 in Switzerland: a multicentre, retrospective study.

Congenital syphilis is a rare complication of syphilis in pregnant women. Vertical transmission may occur at any time during pregnancy. The incidence of congenital syphilis has been increasing worldwide. Congenital syphilis has been a notifiable disease for many years in Switzerland but reporting does not include maternal features associated with syphilis in pregnancy or infant's subsequent development. We described syphilis cases among pregnant women screened over a 10-year period in Switzerland and subsequent cases of congenital syphilis, in order to identify maternal risk profiles and to optimise prevention. Second, we compared the characteristics of pregnant women screened early (1st trimester) vs late in pregnancy (2nd or 3rd trimester). Finally, we assessed the risk factors for premature birth among these women with syphilis. A multicentre retrospective study conducted in Swiss hospitals from 2012 to 2021, including pregnant women who screened positive for syphilis (Treponema pallidumhaemagglutination assay [TPHA] /T. pallidumparticle agglutination assay [TPPA ] ≥1:80) and newborns exposed toT. pallidumin utero and/or congenitally infected and with a positive syphilis serology at birth. Data were collected from medical records. A total of 147 syphilis-positive pregnant women and 102 infants were included. A history of treated syphilis was known for 44% (65/147) of the mothers corresponding to a serological scar and the remaining 56% (82/147) were newly identified syphilis cases. Syphilis screening was done during the first trimester in 54%, second trimester in 29% and third trimester in 13% of cases. Two babies were diagnosed with congenital syphilis (1.96%). Several potential factors that could contribute to women's risk of syphilis during pregnancy were identified such as a foreign origin (93% of mothers), lack of healthcare insurance (25%), no employment status (37%), drug use (5%), co-infection with other sexually transmitted infections (24%) and a late first antenatal consultation (42%). The number of pregnant women without insurance was higher in women diagnosed in the second or third trimester than in those diagnosed in the first trimester (odds ratio 0.41; 95% CI 0.19-0.89; p = 0.024). Syphilis diagnosed in the second or third trimester was associated with a late first antenatal consultation (odds ratio 77.82; 95% CI 9.81-617.21; p <0.001). A high rate of intrauterine growth retardation and of preterm birth was observed in newborns (18% versus 6% in Switzerland in 2022). Congenital syphilis remains rare in Switzerland. However, we found potential maternal factors associated with a positive syphilis serology during pregnancy, which can help to improve future prevention measures. The study protocol was registered on ClinicalTrials.gov (ID NCT05975502).

Antipsychotic, benzodiazepine and Z-drug prescriptions in a Swiss hospital network in the Choosing Wisely and COVID-19 eras: a longitudinal study.

Physicians frequently prescribe antipsychotics off-label to treat, among others, insomnia and anxiety. The Swiss "smarter medicine - Choosing Wisely" campaign has tried to raise awareness about the risks and to limit benzodiazepine and Z-drug prescriptions. In the Italian-speaking part of Switzerland, our network of public hospitals joined the campaign with the aim of avoiding unnecessary benzodiazepine and Z-drug treatments, with prescription monitoring, benchmarking and educational contributions. Considering the risks of a possible shift towards the prescription of antipsychotics, and aware of the potential role of the COVID-19 pandemic, we decided to analyse the prescription trends of antipsychotics and benzodiazepines/Z-drugs before, during (2016-2017) and after the intervention. For this longitudinal study, we reactivated a continuous monitoring of inpatient benzodiazepine/Z-drug and antipsychotics prescriptions/deprescriptions, paused in 2018 after the end of the internal Choosing Wisely campaign, based on routinely collected observational health data. We screened all demographic, administrative and prescription data of patients admitted to the internal medicine department of the four teaching hospitals (H1-H4) belonging to the EOC (Ente Ospedaliero Cantonale) network, from the fourth quarter of 2014 to the second quarter of 2023. We analysed 74,659 hospital stays (14,645 / 16,083 / 24,285 / 19,646 at hospitals H1 / H2 / H3 / H4 respectively). The mean (± SD) case mix (a metric that reflects the diversity, complexity and severity of the treated patients) and patient age were 1.08 ± 0.14 and 73 ± 2 years. 10.6% and 12.1% of patients received antipsychotics prior to admission and at discharge respectively (new prescriptions 3.3 ± 0.7%; deprescriptions 13.3 ± 5.2%). New prescriptions showed an upward trend, with +0.20% per year (p <0.001). Patients admitted with ongoing antipsychotics therapy increased 0.36% per year (p <0.001). New benzodiazepine/Z-drug prescriptions showed a 0.20% per year decrease (p = 0.01). Patients admitted with ongoing benzodiazepine/Z-drug therapy decreased 0.32% per year (p <0.001). New antipsychotics prescriptions showed differences between hospitals, with H3 above and H2 below the average. The increase in antipsychotics quantitatively matched the decrease in benzodiazepine/Z-drug prescribing, suggesting a shift from one to the other sedative therapy. The same trend was visible in the ongoing prescriptions at admission revealing a similar out-of-hospital approach. This suggests a change in sedative prescribing strategy rather than the choice of alternative, non-pharmacological approaches. Furthermore, the variation between similar services of different hospitals points out the consequences of local prescribing cultures and the importance of continuously monitoring and benchmarking medication prescriptions.

Comparison of SARS-CoV-2 related in-hospital mortality, ICU admission and mechanical ventilation of 1.4 million patients in Germany and Switzerland, 2019 to 2022.

In the 2020 emergence of SARS-CoV-2, global response lacked unified treatment and surveillance, resulting in diverse impacts due to varied healthcare resources and national guidelines. Germany and Switzerland curbed the virusinitially by promptly tracking and testing, bolstered by strong governmental capacity. This study aimed to assess country-specific healthcare disparities and their impact on ICU admission rates, mechanical ventilation, and in-hospital mortality. To enhance healthcare quality using real-world data, the "Initiative of Quality Medicine" (IQM) was established. Pseudonymised routine data from participating hospitals, during 01/01/2019-31/12/2022, was retrospectively analysed, focusing on patients with SARI ± SARS-CoV-2-infection (U07.1). Cohorts were matched based on various factors and multivariable analyses included logistic regression. 1.421.922 cases of SARI ± U07.1 involving 386 German and 41 Swiss hospitals were included. Patients in Germany were older (mean: 69.4 vs. 66.5years) and had more comorbidities than in Switzerland (p < .001). Patients in Germany were also more likely to be treated on ICU (28% vs. 20%, OR 1.5 95% CI 1.5-1.6, p < .001) and mechanically ventilated (20% vs. 15%, OR 1.4, 95% CI 1.4-1.5, p < .001). The in-hospital mortality was significantly higher in Germany than in Switzerland (21% vs. 12%, OR 2.0, 95% CI 1.9-2.0, p < .001). Matched cohorts showed reduced differences, but Germany still exhibited higher in-hospital mortality. Discrepancies were evident in both pre-pandemic and pandemic analyses, highlighting existing disparities between both countries. IQM data from Swiss and German hospitals reveals country-specific differences in SARI ± U07.1 outcomes, highlighting higher in-hospital mortality in Germany, with uncertain causes suggesting varied treatments and resources.

Comparison of the effectiveness of open, laparoscopic, and robotic-assisted radical prostatectomies based on complication rates: a retrospective observational study with administrative data from Switzerland

BackgroundRadical prostatectomies can be performed using open retropubic, laparoscopic, or robot-assisted laparoscopic surgery. The literature shows that short-term outcomes (in particular, inpatient complications) differ depending on the type of procedure. To date, these differences have only been examined and confirmed in isolated cases based on national routine data.MethodsThe data was based on the Swiss Medical Statistics from 2016 to 2018 from a national survey of administrative data from all Swiss hospitals. Cases with the coded main diseases neoplasm of the prostate (ICD C61) and the main treatments of laparoscopic (CHOP 60.5X.20) or retropubic (CHOP 60.5X.30) radical prostatectomies were included, resulting in a total sample size of 8,593 cases.ResultsA procedure-related complication occurred in 998 cases (11.6%). By surgical procedure, complication rates were 10.1% for robotic-assisted laparoscopic radical prostatectomy 9.0% for conventional laparoscopic radical prostatectomy and 17.1% for open retropubic radical prostatectomy (p < 0.001). Conventional and robotic-assisted laparoscopic radical prostatectomies had a significantly lower risk of complications than retropubic procedures. Moreover, the risk of a procedure-related complication was almost twice as high in cases operated on retropubically; however, no significant difference was found between conventional and robotic-assisted laparoscopic cases.DiscussionThe use of a surgical robot showed no advantages in radical prostatectomies regarding procedure-related during the hospital stay. However, both conventional and robotic-assisted laparoscopically operated radical prostatectomies show better results than open retropubic procedures. Further studies on the long-term course of patients based on claims data are needed to confirm the inherent benefits of surgical robots in tandem with them being increasingly employed in hospitals.

Monitoring equity in the delivery of health services: a Delphi process to select healthcare equity indicators.

Health equity is a key component of quality of care and an objective for a growing number of quality improvement projects for deontological, ethical, public health and economic reasons. To monitor equity in the delivery of health services in Switzerland, there is a need to implement valid, measurable and actionable equity indicators, along with vulnerability stratifiers such as migrant status, which could lead to differences in quality of care. The aim of this study was to develop a set of healthcare equity indicators and stratifiers targeting inpatient and outpatient populations and to test their feasibility. A scoping literature review and inputs from a national interprofessional expert taskforce provided a set of indicators and vulnerability stratifiers. The most valid and measurable indicators and stratifiers were retained using a Delphi process. They were then operationalised, and their implementation tested in three Swiss hospitals from the three language regions. A taskforce of 18 experts, including a patient representative, selected 11 indicators that evaluate structures, processes and outcomes, and five vulnerability stratifiers. Although most indicators and stratifiers could be implemented in all three hospitals, data availability was limited for some variables, including patient satisfaction and access to interpreters for foreign-language patients. The equity indicators and stratifiers identified by this two-stage process have content validity, wide patient coverage and are focused on inequities in the healthcare system that are actionable through improvement projects. Both the indicators and the project methodology could be replicated in institutions aiming for more equitable care.

B-125 Laboratory Profiles for Diagnostic Workup of Acute Abdominal Pain in the Emergency Department: A Comparative Study of University and Non-University Acute Care Hospitals in Germany and Switzerland

Abstract Background Laboratory medicine plays a fundamental role in patient care, especially in emergency departments where rapid diagnosis is critical to the efficient management of high patient volumes. With the aim of simplifying and standardizing laboratory requests, laboratory profiles have widely been established. This study uses the laboratory profile for “acute abdominal pain” as an example to illustrate the extent to which the laboratory profiles used in hospitals differ from each other and whether they are in line with current scientific recommendations. Methods Hospital data and laboratory profiles for “acute abdominal pain” from 18 hospitals, 9 from Germany and 9 from Switzerland, were analyzed and compared. The hospitals were distinguished by bed size, inpatient and outpatient case numbers, country affiliation and university level. In addition, an 'evidence-based laboratory profile' for acute abdominal pain was created based on current guidelines for the five most important causes of acute abdominal pain and compared with hospital laboratory profiles. Results German hospitals include significantly more laboratory parameters into acute abdominal pain profiles than Swiss hospitals (p = 0,0052). No significant differences in the number of laboratory parameters were found between university and non-university hospitals (p = 0,0507). There is a significant positive correlation between the hospital bed size and the number of laboratory parameters in the profiles (r = 0,5521). The number of inpatient cases in a hospital are also positively correlated with the number of laboratory parameters in the profiles (r = 0,4751). The number of outpatient cases ist not associated with the number of laboratory in the profiles parameters (r = 0,0599). The evidence-based laboratory profile for acute abdominal pain includes 21 laboratory parameters, but only two of them are collected by all investigated hospitals (bilirubin and ALAT).There were no significant differences in the fulfillment of the evidence-based laboratory profile between Germany and Switzerland, or between university or non-university status. Conclusions The study shows that there are quantitative and qualitative differences between the laboratory profiles for investigation of acute abdominal pain within the participating hospitals. In Germany and Switzerland there is no consensus on which analyses to include into a profile investigating acute abdominal pain. For increasing efficiency and accuracy of laboratory testing in in the diagnostic workup of acute abdominal pain it seems advisable to obtain consensus on what to reasonably include into a profile on a national or international level.

Predicting collaborative practice between midwives and obstetricians: A regression analysis.

Effective collaborative practice between midwives and obstetricians improves patient safety and obstetrical outcomes, but its implementation remains challenging. Therefore, its determinants need to be better understood. This study examined factors impacting collaborative practice (CP) between these professional groups. This study was a cross-sectional survey that took place in Swiss hospital labor wards in 2021. Collaborative practice perceptions of 70 midwives (57.4% response rate) and 44 obstetricians (29.0% response rate) were assessed using the Interprofessional Collaboration Scale, with the score serving as the main outcome. A total of 13 individual, behavioral, and organizational predictors were analyzed by multiple linear regression. Participants rated collaborative practice with a median score of 3.1 (IQR: 2.8-3.4) out of a maximum score of 4.0. Results showed that five predictors significantly influenced collaborative practice: type of profession (β= -0.180; 95% CI: -0.296 - -0.040, p=0.011), trust/respect (β=0.343; 95% CI: 0.085-0.040, p=0.000), shared visions/goals (β=0.218; 95% CI: 0.030-0.204, p=0.009), workplace (β=0.253; 95% CI: 0.089-0.445, p=0.004) and shared power (β=0.163; 95% CI: 0.042-0.222, p=0.015). The model explained 66% of the variance (adjusted R2) in collaborative practice in labor wards. This study has identified key factors influencing CP in Swiss labor wards: workplace characteristics that require tailored CP models, and a power-sharing culture that fosters trust, respectful interactions and shared goals, requiring active exchange between midwives and obstetricians.

Improving preparation in the emergency trauma room: the development and impact of real-time data transfer and dashboard visualization system.

This study examines, with clinical end users, the features of a visualization system in transmitting real-time patient data from the ambulance to the emergency trauma room (ETR) to determine if the real-time data provides the basis for more informed and timely interventions in the ETR before and after patient arrival. We conducted a qualitative in-depth interview study with 32 physicians in six German and Swiss hospitals. A visualization system was developed as prototype to display the transfer of patient data, and it serves as a basis for evaluation by the participating physicians. The prototype demonstrated the potential benefits of improving workflow within the ETR by providing critical patient information in real-time. Physicians highlighted the importance of features such as the ABCDE scheme and vital signs that directly impact patient care. Configurable and mobile versions of the prototype were suggested to meet the specific needs of each clinic or specialist, allowing for the transfer of only essential information. The results highlight on the one hand the potential need for adaptable interfaces in medical communication technologies that balance efficiency with minimizing additional workload for emergency medical services and show that the use of pre-notification systems in communication between ambulance and hospital can be supportive. Further research is recommended to assess practical application and support in clinical practice, including a re-evaluation of the enhanced prototype by professionals.

Noise in the operating room coincides with surgical difficulty.

Noise in the operating room has been shown to distract the surgical team and to be associated with postoperative complications. It is, however, unclear whether complications after noisy operations are the result of objective or subjective surgical difficulty or the consequence of distraction of the operating room team by noise. Noise level measurements were prospectively performed during operations in four Swiss hospitals. Objective difficulty for each operation was calculated based on surgical magnitude as suggested by the Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM), duration of operation and surgical approach. Subjective difficulty and distraction were evaluated by a questionnaire filled out by the operating room team members. Complications were assessed 30 days after surgery. Using regression analyses, the relationship between objective and subjective difficulty, distraction, intraoperative noise and postoperative complications was tested. Postoperative complications occurred after 121 (38%) of the 294 procedures included. Noise levels were significantly higher in operations that were objectively and subjectively more difficult (59.89 versus 58.35 dB(A), P < 0.001) and operations that resulted in postoperative complications (59.05 versus 58.77 dB(A), P = 0.004). Multivariable regression analyses revealed that subjective difficulty as reported by all members of the surgical team, but not distraction, was highly associated with noise and complications. Only objective surgical difficulty independently predicted noise and postoperative complications. Noise in the operating room is a surrogate of surgical difficulty and thereby predicts postoperative complications.

Hospitalization Trends for Airway Infections and In-Hospital Complications in Cleft Lip and Palate

Cleft lip or palate is a prevalent birth defect, occurring in approximately 1 to 2 per 1000 newborns and often necessitating numerous hospitalizations. Specific rates of hospitalization and complication are underexplored. To assess the rates of airway infection-associated hospitalization, overall hospital admissions, in-hospital complications, and mortality among children with a cleft lip or palate. This nationwide, population-based cohort study used in-hospital claims data from the Federal Statistical Office in Switzerland between 2012 and 2021. Participants included newborns with complete birth records born in a Swiss hospital. Data were analyzed from March to November 2023. Prevalent diagnosis of a cleft lip or palate at birth. Outcomes of interest were monthly hospitalization rates for airway infections and any cause during the first 2 years of life in newborns with cleft lip or palate. In-hospital outcomes and mortality outcomes were also assessed, stratified by age and modality of surgical intervention. Of 857 806 newborns included, 1197 (0.1%) had a cleft lip and/or palate, including 170 (14.2%) with a cleft lip only, 493 (41.2%) with a cleft palate only, and 534 (44.6%) with cleft lip and palate. Newborns with cleft lip or palate were more likely to be male (55.8% vs 51.4%), with lower birth weight (mean [SD] weight, 3135.6 [650.8] g vs 3284.7 [560.7] g) and height (mean [SD] height, 48.6 [3.8] cm vs 49.3 [3.2] cm). During the 2-year follow-up, children with a cleft lip or palate showed higher incidence rate ratios (IRRs) for hospitalizations due to airway infections (IRR, 2.33 [95% CI, 1.98-2.73]) and for any reason (IRR, 3.72 [95% CI, 3.49-3.97]) compared with controls. Additionally, children with cleft lip or palate had a substantial increase in odds of mortality (odds ratio [OR], 17.97 [95% CI, 11.84-27.29]) and various complications, including the need for intubation (OR, 2.37 [95% CI, 1.95-2.87]), extracorporeal membrane oxygenation (OR, 2.89 [95% CI, 1.81-4.63]), cardiopulmonary resuscitation (OR, 3.25 [95% CI, 2.21-4.78]), and respiratory support (OR, 1.94 [95% CI, 1.64-2.29]). In this nationwide cohort study, the presence of cleft lip or palate was associated with increased hospitalization rates for respiratory infections and other causes, as well as poorer in-hospital outcomes and greater resource use.

Pressure injury incidence measurement as a quality improvement strategy: national trends in Switzerland.

This study sought to determine the risk-adjusted (controlled for patient characteristics) trend in pressure injury (PI) incidence in Switzerland. A secondary data analysis was conducted. The data originated from the national PI quality measurement based on a multicentre cross-sectional design with repeated annual measurements. Descriptive statistics, a Cochran-Armitage trend test and logistic (multilevel) regression modelling were applied. The analysis sample comprised 123,715 patients from 230 hospitals over 10 survey years (2011-2019 and 2022). The incidence of descriptive PI varied in Switzerland between 3.7% and 5.6% over the survey years. No linear trend could be found when patient characteristics were not considered. A non-linear trend was detected when controlling for patient characteristics and the time effect (repeated measurement). This was also reflected in the plotted risk-adjusted incidence, which revealed a decrease followed by a levelling off. When only considering the incidence of PIs rated category 2 and higher, there was also a non-linear decreasing trend when controlling for patient characteristics and time effects. If the incidence per survey year were estimated on the basis of patient characteristics, an increase in the incidence would have been expected. Although patients' risk of developing a PI increased between 2011-2022, the incidence of PIs in Switzerland first decreased and then levelled off. The results indicated that care quality in Swiss hospitals has improved regarding PIs. Nevertheless, in view of demographic trends and increasing staff shortages, it is important to continue to monitor PI incidence and to invest in PI prevention.

Identifying the drivers of overall rating of cancer care: Insights from the second wave of the Swiss Cancer Patient Experiences study.

Patient experience surveys gather information on various aspects of care via numerous survey items. Identifying the most critical areas of patient experience to prioritize for quality care improvement can be challenging. The objective of this study was to determine which care experience items are the drivers influencing patients' overall rating of cancer care. Data from 2750 adult patients with cancer from the second wave of the Swiss Cancer Patient Experiences study were analyzed. This cross-sectional survey was conducted in eight Swiss hospitals from September 2021 to February 2022. Stepwise logistic regression examined the relationship between overall care rating and 29 patient experience items covering different patient-centered care dimensions while adjusting for sociodemographic and health variables. Overall, patients rated their cancer care experience at 8.9 out of 10. Stepwise regression identified seven drivers contributing to overall care rating. The strongest drivers were "professionals worked well together" (odds ratio [OR],4.81) and "tests were not repeated" (OR,2.09) from the coordination and integration dimension, "offered support for symptoms during treatment" (OR,2.11) from the physical comfort dimension, followed by "hospital staff ensured available home support" (OR,1.99), "offered to see health professional for concerns" (OR,1.91), "treatment options were explained" (OR,1.75), and "involved in treatment decisions as desired" (OR,1.68). This study evaluated the care experiences of patients with cancer with a comprehensive tool that identified seven key factors independently associated with overall care rating. By concentrating on these areas, hospitals can not only improve the patient care experience but also efficiently allocate resources to quality improvement initiatives.

Predictor Selection for Case Complexity Based on Routine Data for Needs-Based and Competence-Based Staff Planning.

Due to nursing staff shortage and growing nursing care demand, resource allocation and optimal task distribution have become primary concerns of nursing management. Grade mix analysis based on nursing interventions and nurse qualifications from routine patient documentation can support this. Case complexity is a key linking factor of nursing interventions, workload, and grade mix. This study determined case complexity predictors based on one year of routine patient documentation (n = 3,373 cases) from a Swiss hospital and predicted the patient clinical complexity level via weighted cumulative logistic regression models. Significant predictors were sex, age, pre-admission residence, admission type, self- care index, pneumonia risk, and number of nursing interventions. The models' accuracy is limited yet appropriate for applications such as needs- and competence- based staff-planning. After calibration via in-hospital data it could support nursing management in these tasks. The next step is now to test the model in a clinical setting.

Usability Evaluation in a Remote Access Scenario.

We present an approach to use the think aloud method for formative usability evaluation for medical software in a remote access scenario which combines researchers in two different locations and test persons distributed across five Swiss hospitals into one study using MS-Teams. We could show that a) these tests can be performed remote in a tight time schedule and b) that results valuable for the formative development of the examined mockup solution could be achieved. Two sessions had to be rescheduled for technical problems but all test persons could complete the think aloud study in 30 minutes at their usual working environment. This offers the opportunity to software providers to develop medical software with better usability in close cooperation with future users.

Impact of the Covid-19 pandemic on inpatient health care in Switzerland 2020-2021-A descriptive retrospective study using admission data of all Swiss hospitals.

As part of the Covid-19-restrictions in Switzerland, a federal ban on non-urgent examinations and treatments was applied to all hospitals during six weeks in spring 2020 ("spring lockdown"). The aim of this study was to comprehensively investigate the consequences of the Covid-19 pandemic on Swiss inpatient admissions based on data of all hospitals, focusing on selected procedures of different medical urgency. The study includes all acute care inpatient cases (including Covid-19 cases, excluding cases in psychiatry and rehabilitation) according to the Swiss Medical Statistics of Hospitals. Besides the total number of admissions, subdivided by regions, hospital types and age groups, we focused on selected procedures representing different medical urgency: elective surgeries, cancer surgeries, and emergencies. Procedures were selected based on expert interviews. We compared the number of admissions during spring lockdown and for the whole years 2020 and 2021 in absolute numbers and in percentage changes to the corresponding periods in 2019 (baseline year). During spring lockdown, the number of admissions decreased by 47,156 (32.2%) without catch-up effect by the end of 2020 (-72,817 admissions/-5.8%). With procedure-specific decreases of up to 86%, the decline in admissions was largest for elective surgery, a decline that was only fully reversed in the case of a few procedures, such as joint arthroplasty. Strikingly, admissions due to emergencies also substantially decreased during spring lockdown (stroke -14%; acute myocardial infarction STEMI: -9%, NSTEMI: -26%). Results for the selected procedures in cancer surgery showed no consistent pattern. In 2021, admission numbers for most procedures reached or even exceeded those in 2019. The substantial reduction in admissions, particularly in elective procedures, may reflect the impact of the triage in favor of anticipated Covid-19-cases during spring lockdown. By the end of 2020, admissions were still at lower levels relative to the previous, pre-pandemic year. The numbers in 2021 reached the same levels as those in 2019, which suggests that the Covid-19 pandemic only temporarily impacted inpatient health care in Switzerland. Long-term consequences of the observed reduction in admissions for emergencies and cancer surgery need to be investigated at the individual level.

Preferences of pregnant women for postpartum thromboprophylaxis: the bicentric PREFER-PostPartum study

BackgroundClinical guidelines for postpartum thromboprophylaxis differ due to its uncertain effect and varying preferences of experts. Women’s preferences for postpartum thromboprophylaxis are unknown, although they may inform practices and future research. ObjectivesOur aim was to elicit the pregnant women’s preferences for postpartum thromboprophylaxis according to different risks of venous thromboembolism (VTE) and bleeding. MethodsIn 2 Swiss and French maternity hospitals, we conducted structured interviews of pregnant or postpartum women. Participants were instructed on pulmonary embolism, deep vein thrombosis, postpartum hemorrhage, and subcutaneous injections of low-molecular-weight heparin (LMWH). First, we randomized women to either standard gamble or time trade-off (2 different validated methods) to estimate the utilities (quality of life, from 0 to 1) of these health states. Second, we elicited the preference for the use of short-term postpartum thromboprophylaxis with LMWH vs none across different risks of postpartum VTE and bleeding through direct-choice exercises. ResultsAmong 122 participants, median (IQR) health state utilities were 0.725 (0.30-0.925) for pulmonary embolism, 0.75 (0.40-0.97) for postpartum hemorrhage, 0.85 (0.60-0.97) for deep vein thrombosis, and 0.96 (0.96-0.999) for LMWH injections. The median risk of postpartum VTE for preference of the use of postpartum thromboprophylaxis over no treatment was 0.1% (IQR, 0.01%-0.50%) without LMWH-associated bleeding risk and 0.2% (IQR, 0.1%-5%) with a 1% bleeding risk. ConclusionEuropean pregnant women appear to have a high willingness for 10-day postpartum thromboprophylaxis, preferred over no treatment even for low risks of postpartum VTE. This perspective from patients supports the urgent need for a randomized trial evaluating the efficacy and safety of postpartum thromboprophylaxis.

Similar QALY gain in primary and revision knee arthroplasty: A cost analysis and Markov model.

The aim of this study isto investigate the cost-effectiveness of revision total knee arthroplasty compared to primary total knee arthroplasty in terms of cost-per-quality-adjusted life year (QALY). Data were retrieved for all primary and revision total knee replacement (TKA) procedures performed at a tertiary Swiss hospital between 2006 and 2019. A Markov model was created to evaluate revision riskand we calculated lifetime QALYgain and lifetime procedure costs through individual EuroQol 5 dimension (EQ-5D) scores, hospital costs, national life expectancy tablesand standard discounting processes. Cost-per-QALY gain was calculated for primary and revision procedures. EQ-5D data were available for 1343 primary and 103 revision procedures. Significant QALY gains were seen following surgery in all cases. Similar, but significantly more QALYs were gained following primary TKA (PTKA) (5.67 ± 3.98) than following revision TKA (RTKA) (4.67 ± 4.20). Cost-per-QALY was €4686 for PTKA and €10,364 for RTKA. The highest average cost-per-QALY was seen in two-stage RTKA (€12,292), followed by one-stage RTKA (€8982). RTKA results in a similar QALY gain as PTKA. The costs of achieving health gain are two to threetimes higher in RTKA, but both procedures are highly cost-effective. Economic level II.

Technostress experience in inpatient medical care in German and Swiss hospitals: current state of research

Zusammenfassung Hintergrund Ziel dieser Arbeit ist die Darstellung der aktuellen Studienlage zur Prävalenz und Ausprägung von Technostresserleben in der stationären medizinischen Versorgung in deutschen und schweizerischen Kliniken. Dieses stellt ein aufkommendes Risiko im Zusammenhang mit dem zunehmenden Einsatz von Informations- und Kommunikationstechnologien (IKT) im Gesundheitswesen dar. Methodik Mithilfe einer systematischen Literaturrecherche wurden unter Verwendung von Schlüsselbegriffen vordefinierten Ein- und Ausschlusskriterien 49 Artikel identifiziert, von denen 9 Studien einbezogen worden sind. Ergebnisse Theoretische Grundlage der in dieser Arbeit analysierten Studien bildet überwiegend das Technostress-Konzept von Ragu-Nathan et al. (2008) mit den Subkategorien Techno-overload, Techno-complexity, Techno-insecurity, Techno-uncertainty und Techno-invasion. Bei fast allen Studien handelt es sich um Querschnittsstudien, welche sich auf die Ausprägung von Technostress unter Ärzt:innen, seltener Pfleger:innen und anderen Gesundheitsberufen konzentriert haben sowie auf die Analyse der auslösenden und abschwächenden Faktoren von Technostress und Auswirkungen auf organisationale und gesundheitsbezogene Outcomes (u. a. Produktivität, Arbeitszufriedenheit, Burnout). Die aktuelle Studienlage spricht hierbei für ein moderates Level von Technostress, wobei die höchsten Ausprägungen für die Subkategorien „Techno-overload“ und „Techno-uncertainty“ erhoben worden sind. Schlussfolgerung Ärzt:innen und Pfleger:innen zeigen die höchsten Ausprägungen von Technostresserleben, gefolgt von Medizinisch-technischen, Medizinisch-therapeutischen und anderen Berufen (z. B. Sozialarbeiter:innen, Psycholog:innen, Hebammen). Es mangelt jedoch an empirischen Studien zu nichtärztlichen Gesundheitsberufen sowie an Interventionsstudien, die insbesondere Coping-Strategien im Umgang mit arbeitsbezogenem Technostresserleben evaluieren und darauf basierende Handlungsempfehlungen für Gesundheitsorganisationen aussprechen.

Dermatological emergencies and determinants of hospitalization in Switzerland: A retrospective study.

Dermatologic conditions are estimated to account worldwide for approximately 8% of all visits at emergency departments (EDs). Although rarely life-threatening, several dermatologic emergencies may have a high morbidity. Little is known about ED consultations of patients with dermatological emergencies and their subsequent hospital disposal. We explore determinants and clinical variables affecting patients' disposal and hospitalization of people attending the ED at a Swiss University Hospital, over a 56-month observational period, for a dermatological problem. De-identified patients' information was extracted from the hospital electronic medical record system. Generalized estimating equations were used to explore determinants of patient's disposition. Out of 5096 consecutive patients with a dermatological main problem evaluated at the ED, 79% of patients were hospitalized after initial assessment. In multivariable analyses, factors which were significantly associated with an increased admission rate included length of ED stay, age ≥ 45 years, male sex, distinct vital signs, high body mass index, low oxygen saturation, admission time in the ED and number and type of dermatological diagnoses. Only 2.2% of the hospitalized patients were admitted to a dermatology ward, despite the fact that they had dermatological diagnoses critically determining the diagnostic related group (DRG) payment. The number of patients managed by dermatologists during in-patient treatment significantly decreased over the study period. Our study identifies a number of independent predictors affecting the risk of hospital admission for patients with dermatological conditions, which may be useful to improve patients' disposal in EDs. The results indicate that the dermatological specialty is becoming increasingly marginalized in the management of patients in the Swiss hospital setting. This trend may have significant implications for the delivery of adequate medical care, outcomes and cost-effectiveness. Dermatologists should be more engaged to better position their specialty and to effectively collaborate with nondermatologists to enhance patient care.

Surgical Antimicrobial Prophylaxis in Low-Risk Cholecystectomies is Associated with Fewer Surgical Site Infections: Nationwide Cohort Study in Switzerland.

To assess whether administration of surgical antimicrobial prophylaxis (SAP) versus absence of SAP is associated with a decreased risk of surgical site infections (SSI) after low-risk cholecystectomies (LR-CCE). Current guidelines do not recommend routine SAP administration prior to LR-CCE. This cohort study included adult patients who underwent LR-CCE and were documented by the Swissnoso SSI surveillance system between 1/2009-12/2020 at 66 Swiss hospitals. LR-CCE was specified as elective endoscopic surgery, age <70, no active cholecystitis, ASA score <3, operating time <120 minutes without implantation of foreign material. Exposure was defined as the administration of cefuroxime or cefazoline ± metronidazole within 120 minutes prior to incision versus no SAP administration. Our main outcome was occurrence of SSI until day 30. Logistic regression models were used to adjust for institutional, patient, and perioperative variables. Of 44 682 surveilled adult cholecystectomy patients, 12 521 (8 726 women [69.7%]; median [IQR] age, 49.0 [38.1-58.2] years), fulfilled inclusion criteria. SSI was identified in 143 patients (1.1%). SAP was administered in 9 269 patients (74.0%) and was associated with a lower SSI rate (adjusted odds ratio [aOR], 0.50; 95% CI, 0.35-0.70; P < 0.001). The number needed to treat to prevent one SSI episode is 100. The overall LR-CCE SSI rate was 1.1%. SAP was associated with a 50% lower overall SSI rate. Patients undergoing LR-CCE may benefit from routine surgical antimicrobial prophylaxis.
