Nothing feels better than home ::why must nursing‐led integrated care interventions for older people with chronic conditions in hospital‐at‐home be considered?
No full textMeasuring nurses’ knowledge and awareness of climate change and climate-associated diseases ::systematic review of existing instruments
No full textBackground: As early as 1995, the Institute of Medicine suggested that nurses were inadequately prepared for and educated about climate change and its health consequences. The aim of this systematic review is to identify the most reliable, robust, and valid instruments for measuring nurses’ knowledge and awareness of climate change and climate-associated diseases. Methods: Included studies were appraised using the Mixed-Methods Appraisal Tool and the Appraisal tool for Cross-Sectional Studies. The psychometrics and clinimetrics of the instruments were evaluated using the COSMIN Risk of Bias checklist and the COSMIN methodology for assessing content validity. Results: Medline, PubMed, Embase, CINAHL Ebesco, Cochrane Library Wiley, Web of Science Core Collection, Trip Database, JBI OVID SP, GreenFILE EBSCO, Google Scholar, ProQuest Dissertations and Theses Global, and DART-EU were consulted. The 14 studies retained identified eight different instruments evaluating attitudes, perceptions, environmental awareness, environmental sensitivity, environmental attitudes, behaviours, motivation, concern, optimism, and experience. This review is reported according to the PRISMA guidelines. Conclusions: The New Ecological Paradigm Scale (NEPS) and the Climate, Health, and Nursing Tool (CHANT) are the most reliable, robust, and valid instruments for measuring nurses’ knowledge and awareness of climate change and climate-associated diseases
Time constraints and workload in the computed tomography department
No full textIntroduction: The escalating use of Computed Tomography (CT) has promoted higher radiographer workload, which can contribute to an increase of risks such as stress, job dissatisfaction, and potential health and safety issues. This study aimed to assess the impact of organizational, spatial, and temporal factors on procedures and workload in a CT unit, emphasizing patient safety and radiographer well-being. Addressing time pressure and optimizing workplace ergonomics are crucial in maintaining a balance between efficiency and quality, ensuring safe practices in modern medical imaging units. Methods: The study was conducted in a Swiss university hospital CT unit and employed the Systems Engineering Initiative for Patient Safety (SEIPS) model to analyse the radiographers’ workflow and time constrains. Observations and tasks’ analysis were used to collect data, including timing and location of tasks performed by radiographers. Results: The radiographers’ workflow in the CT department is com- plex, involving multiple tasks. The entire process spans from 26 to 41 min but the Machine-Time (time spent inside the CT room) ranged from 10 to 16 min. The study identified inefficiencies in the workflow, namely in time spent on patient preparation and unsuited machine- time rate. The layout of the department, including limited space in the preparation area, contributing to ergonomic challenges for radiographers. Organizational factors, such as scheduling practices, also impacted workflow. The examination durations varied by type of scan and patient, leading to time pressure and potential safety concerns. Conclusions: The study highlighted the need for more realistic time allocation in CT examinations to improve patient and radiographer safety. Recommendations include extending machine-time rate, adapting examination durations based on the type of CT, and assigning a dedicated radiographer for order review. It is also crucial im- proving the working environment to accommodate ergonomic needs. Addressing these issues can enhance the efficiency and safety of CT departments, benefiting both patients and radiographers. Implications for Practice: Healthcare organizations should consider these study recommendations to improve the efficiency and safety of CT departments. By implementing the recommended changes, such as adjusting CT-time rate and optimizing working environments, radiographer satisfaction and patient safety can be increased, ultimately leading to safer and more effective CT services.Introduction : L’utilisation croissante de la tomodensitométrie (TDM) a entraîné une augmentation de la charge de travail des radiographes, ce qui peut contribuer à accroître les risques comme le stress, l’insatisfaction au travail et les problèmes potentiels de santé et de sécurité. Cette étude visait à évaluer l’incidence des facteurs organisationnels, spatiaux et temporels sur les procédures et la charge de travail dans une unité de TDM, en mettant l’accent sur la sécurité des patients et le bien- être des radiographes. La gestion de la pression temporelle et l’optimisation de l’ergonomie du lieu de travail sont essentielles pour maintenir un équilibre entre l’efficacité et la qualité, et garantir des pratiques sûres dans les unités d’imagerie médicale modernes. Méthodologie : L’étude a été menée dans un service de TDM d’un hôpital universitaire suisse et a utilisé le modèle SEIPS (Systems Engineering Initiative for Patient Safety) pour analyser le flux de travail et les contraintes de temps des radiographes. Les observations et l’analyse des tâches ont été utilisées pour recueillir des données, notamment sur le moment et l’emplacement des tâches effectuées par les radiographes. Résultats : Le flux de travail des radiographes dans le service de TDM est complexe et comporte de multiples tâches. L’ensemble du processus dure de 26 à41 minutes, mais le temps machine (temps passé à l’intérieur de la salle de TDM) varie de 10 à16 minutes. L’étude a identifié des inefficacités dans le flux de travail, notamment le temps consacré à la préparation du patient et le taux de temps machine in- adapté. L’agencement du service, y compris l’espace limité dans la zone de préparation, contribue aux problèmes d’ergonomie pour les radio- graphes. Des facteurs organisationnels, tels que les pratiques de programmation, ont également eu une incidence sur le flux de travail. Les durées d’examen variaient en fonction du type de scanner et du patient, ce qui a entraîné des contraintes de temps et des problèmes de sécurité potentiels. Conclusions : L’étude a mis en évidence la nécessité d’une répartition plus réaliste du temps lors des examens de TDM afin d’améliorer la sécurité des patients et des radiographes. Les recommandations comprennent l’extension du taux de temps machine, l’adaptation des durées d’examen en fonction du type de TDM et l’affectation d’un radiographe dédié à la révision des ordonnances. Il est également essentiel d’améliorer l’environnement de travail pour répondre aux besoins ergonomiques. La résolution de ces problèmes peut améliorer l’efficacité et la sécurité des services de TDM, au bénéfice des patients et des radiographes. Implications pour la pratique : Les établissements de santé devraient tenir compte des recommandations de cette étude pour améliorer l’efficacité et la sécurité des services de TDM. En mettant en œuvre les changements recommandés, tels que l’ajustement du taux de temps de TDM et l’optimisation des environnements de travail, la satisfaction des radiographes et la sécurité des patients, conduisant en fin de compte à des services de TDM plus sûrs et plus efficaces
An empirical study of the usage of checksums for web downloads
No full textChecksums, typically provided on webpages and generated from cryptographic hash functions (e.g., MD5, SHA256) or signature schemes (e.g., PGP), are commonly used on websites to enable users to verify that the files they download have not been tampered with when stored on possibly untrusted servers. In this paper, we elucidate the current practices regarding the usage of checksums for web downloads (hash functions used, visibility and validity of checksums, type of websites and files, etc.), as this has been mostly overlooked so far. Using a snowball-sampling strategy for the 200000 most popular domains of the Web, we first crawled a dataset of 8.5M webpages, from which we built, through an active-learning approach, a unique dataset of 277 diverse webpages that contain checksums. Our analysis of these webpages reveals interesting findings about the usage of checksums. For instance, it shows that checksums are used mostly to verify program files, that weak hash functions are frequently used, and that a non-negligible proportion of the checksums provided on webpages do not match that of their associated files. Finally, we complement our analysis with a survey of the webmasters of the considered webpages (N = 26), thus shedding light on the reasons behind the checksum-related choices they make
Capstone ::mobility modeling on smartphones to achieve privacy by design
No full textSharing location traces with context-aware service providers has privacy implications. Location-privacy preserving mechanisms, such as obfuscation, anonymization and cryptographic primitives, have been shown to have impractical utility/privacy tradeoff. Another solution for enhancing user privacy is to minimize data sharing by executing the tasks conventionally carried out at the service providers' end on the users' smartphones. Although the data volume shared with the untrusted entities is significantly reduced, executing computationally demanding server-side tasks on resource-constrained smartphones is often impracticable. To this end, we propose a novel perspective on lowering the computational complexity by treating spatiotemporal trajectories as space-time signals. Lowering the data dimensionality facilitates offloading the computational tasks onto the digital-signal processors and the usage of the non-blocking signal-processing pipelines. While focusing on the task of user mobility modeling, we achieve the following results in comparison to the state of the art techniques: (i) mobility models with precision and recall greater than 80%, (ii) reduction in computational complexity by a factor of 2.5, and (iii) reduction in power consumption by a factor of 0.5. Using real-world mobility datasets, we demonstrate the suitability of our technique to function on smartphones
Geodabs ::trajectory indexing meets fingerprinting at scale
No full textFinding trajectories and discovering motifs that are similar in large datasets is a central problem for a wide range of applications. Solutions addressing this problem usually rely on spatial indexing and on the computation of a similarity measure in polynomial time. Although effective in the context of sparse trajectory datasets, this approach is too expensive in the context of dense datasets, where many trajectories potentially match with a given query. In this paper, we apply fingerprinting, a copy-detection mechanism used in the context of textual data, to trajectories. To this end, we fingerprint trajectories with geodabs, a construction based on geohash aimed at trajectory fingerprinting. We demonstrate that by relying on the properties of a space filling curve geodabs can be used to build sharded inverted indexes. We show how normalization affects precision and recall, two key measures in information retrieval. We then demonstrate that the probabilistic nature of fingerprinting has a marginal effect on the quality of the results. Finally, we evaluate our method in terms of performances and show that, in contrast with existing methods, it is not affected by the density of the trajectory dataset and that it can be efficiently distributed

Improving general practitioners’ approaches to functional somatic syndromes ::a pilot training program with a focus on compassion and communication
No full textBackground : Functional somatic syndromes are common in primary care and represent a challenge for general practitioners (GPs), with a risk of deterioration in the doctor-patient relationship, and of compassion fatigue on the part of the physician. Little is known about how to teach better management of these symptoms. Methods : The aim of our scientific team was to develop a training session about functional somatic syndromes for GPs, with the objective to improve the therapeutic attitude of the participants. The first session of the training was constructed as a pilot session, followed by a qualitative study to complete content validation. The educational framework of the training session is multimodal and includes theory on the pathophysiology of functional somatic syndromes, communication skills, and introspective learning including an introduction to compassion meditation. 20 physicians attended the pilot training session. 10 of them participated in the qualitative study. The qualitative study consisted of five individual semi-structured interviews and one focus group of five persons, investigating the impact of the training session on the clinical practices, as perceived by the participants. The interviews were analysed through an inductive method inspired by Malterud’s systematic text condensation strategy. Results : We identified three main themes in the responses of the participants: (1) the crucial issue of putting a name to chronic psychosomatic suffering; (2) the importance of self-compassion for physicians; (3) changes in therapeutic attitude fostering a reconciliation between “self” and “care”. Participants expressed a need for more regular meetings of this type. The opportunity to share their negative feelings about therapeutic relationship within a peer group, with compassionate supervision of the trainers, seemed to play an important role in the improvement of their self-compassion. Conclusion : A multimodal teaching session seems to help the physicians to feel more comfortable and competent when treating patients with functional somatic syndromes. Including compassion meditation in the teaching seems a promising tool to prevent compassion fatigue
