Clinicians use these tools to rapidly consult the evidence at the point of care, a practice which has been found to reduce the time patients spend in hospitals, promote the quality of care and improve healthcare outcomes. Such tools include Medscape, VisualDx, Clinical Key, DynaMed, BMJ Best Practice and UpToDate. However, use of such tools has not yet been fully embraced in low-resource settings such as Uganda. Objective: This paper intends to collate data on the use and uptake of one such tool, UpToDate, which was provided at no cost to five medical schools in Uganda. Methods: Free access to UpToDate was granted through the IP addresses of five medical schools in Uganda in collaboration with Better Evidence at The Global Health Delivery Project at Harvard and Brigham and Women’s Hospital and Wolters Kluwer Health. Following the donation, medical librarians in the respective institutions conducted training sessions and created awareness of the tool. Usage data was aggregated, based on logins and content views, presented and analyzed using Excel tables and graphs. Results: The data shows similar trends in increased usage over the period of August 2022 to August 2023 across the five medical schools. The most common topics viewed, mode of access (using either the computer or the mobile app), total usage by institution, ratio of uses to eligible users by institution and ratio of uses to students by institution are shared. Conclusion: The study revealed that the tool was used by various user categories across the institutions with similar steady improved usage over the year. These results can inform the librarians as they encourage their respective institutions to continue using the tool to support uptake of point-of-care tools in clinical practice.展开更多

文摘A phase-aware cross-modal framework is presented that synthesizes UWF_FA from non-invasive UWF_RI for diabetic retinopathy(DR)stratification.A curated cohort of 1198 patients(2915 UWF_RI and 17,854 UWF_FA images)with strict registration quality supports training across three angiographic phases(initial,mid,final).The generator is based on a modified pix2pixHD with an added Gradient Variance Loss to better preserve microvasculature,and is evaluated using MAE,PSNR,SSIM,and MS-SSIM on held-out pairs.Quantitatively,the mid phase achieves the lowestMAE(98.76±42.67),while SSIM remains high across phases.Expert reviewshows substantial agreement(Cohen's κ=0.78–0.82)and Turing-stylemisclassification of 50%–70%of synthetic images as real,indicating strong perceptual realism.For downstream DR stratification,fusing multi-phase synthetic UWF_FA with UWF_RI in a Swin Transformer classifier yields significant gains over a UWF_RI-only baseline,with the full-phase setting(Set D)reaching AUC=0.910 and accuracy=0.829.These results support synthetic UWF_FA as a scalable,non-invasive complement to dye-based angiography that enhances screening accuracy while avoiding injection-related risks.
文摘Background:An urban medical group in Dapeng New District was established in 2017 with the objective of enhancing outcomes for common diseases and reinforcing primary care by integrating high‐level hospitals with primary health services.This study aimed to evaluate the performance of the urban medical group using the triangular value chain framework.Methods:The evaluation was conducted using the Donabedian model,focusing on three key dimensions:safety and quality,accessibility,and affordability.Longitudinal data were collected from 2016 to 2022 through government annual reports,the medical insurance bureau,and hospital information systems.Preprogram and postprogram outcome measurements were compared to assess differences and trends,providing a clear picture of the program's effectiveness.Results:Accessibility improved significantly,with the number of hospital beds per 1000 residents increasing from 2.62 in 2017 to 3.76 in 2022.The availability of general practitioners(GPs)also rose markedly,from 0 per 10,000 residents in 2017 to 6.27 in 2022.Regarding safety and quality,the proportion of complex medical procedures conducted within the New District expanded substantially,from 7.35%in 2017 to 38.11%in 2021.Additionally,there was an enhancement in the standardized management rate of chronic diseases.Affordability assessments showed that the proportion of medical income derived from the medical insurance fund increased by nearly 22.81 percentage points between 2012 and 2021.By 2021,75.02%of medical patients were covered by medical insurance,representing an increase of approximately 44 percentage points from 31.19%in 2012.Conclusions:The implementation of the urban medical group in Dapeng New District has led to substantial improvements in healthcare accessibility,safety and quality,and affordability.Future initiatives will focus on advancing the“Dapeng Mode”to generate exemplary healthcare outcomes and minimize disparities in basic health services and health status between urban and rural populations.The reform agenda includes piloting payment reforms and innovative payment models within the Dapeng group,complemented by a health assessment and performance incentive system aimed at encouraging healthcare institutions to prioritize health management.
文摘This mixed-methods study presents a needs analysis to investigate the workplace English language needs of medical students in China who are learning and using English as non-native speakers,the circumstances in which the various language skills are required,and stakeholders’perceived workplace preparedness in the light of language-related instructional provision during medical training.A leading university in China was chosen as the study case.Altogether,294 online questionnaires were collected from undergraduate medical students,graduate medical students and recent graduates working as physicians,and 33 semi-structured individual interviews were conducted with undergraduate medical students,graduate medical students,recent graduates working as physicians,medical teachers,English for Medical Purposes(EMP)teachers,program leaders and English-speaking patients.Results showed that in addition to physicians experiencing pressure to publish scientific articles internationally,participants attached greater importance to physicians’oral English communication ability,especially in undertaking clinical consultations in English,working with medical interpreters or acting as ad hoc interpreters.The participants also reported a lack of relevant EMP courses or trainings available at this university.Given these communicative events that physicians face in China,EMP courses need to include training in these specific areas.
文摘With the rapid advancement of medical artificial intelligence(AI)technology,particularly the widespread adoption of AI diagnostic systems,ethical challenges in medical decision-making have garnered increasing attention.This paper analyzes the limitations of algorithmic ethics in medical decision-making and explores accountability mechanisms,aiming to provide theoretical support for ethically informed medical practices.The study highlights how the opacity of AI algorithms complicates the definition of decision-making responsibility,undermines doctor-patient trust,and affects informed consent.By thoroughly investigating issues such as the algorithmic“black box”problem and data privacy protection,we develop accountability assessment models to address ethical concerns related to medical resource allocation.Furthermore,this research examines the effective implementation of AI diagnostic systems through case studies of both successful and unsuccessful applications,extracting lessons on accountability mechanisms and response strategies.Finally,we emphasize that establishing a transparent accountability framework is crucial for enhancing the ethical standards of medical AI systems and protecting patients’rights and interests.

文摘The World Medical Association’s Declaration of Helsinki(DoH)serves as a key document of ethical guidance advocating principles of medical research involving human participants.Since its inception in 1964,the DoH has undergone several revisions,reflecting a dynamic evolution in our understanding of research ethics,spurred by gaps identified within the document,harms discovered,challenges identified during ongoing research activities,scientific advancements and societal shifts in values.The DoH addresses a challenge and a conflict that may arise between two key aspects of medical research:On one hand,the fundamental obligation of physicians to do no harm,and on the other,the essential need to ensure the efficacy and safety of medical interventions by testing them on human research participants or healthy volunteers.With each revision,increasing emphasis is given to distributive justice and beneficence and not only to patient autonomy.Despite being a comprehensive and concise document,occasional criticism is reported,such as with regards to the impracticability of obtaining informed consent amongst other challenges.This essay will examine the key changes across the DoH's iterations,highlighting the progressive strengthening of participant protection and the evolving relationship between research,societal benefit,and individual rights.

文摘Emergency medical services (EMS) are a vital element of the public healthcare system in China,^([1])providing an opportunity to respond to critical medical conditions and save people’s lives.^([2])The accessibility of EMS has received considerable attention in health and transport geography studies.^([3])One of the optimal gauges for evaluating the accessibility of EMS is the response time,which is defined as the time from receiving an emergency call to the arrival of an ambulance.^([4])Beijing has already reduced the response time to approximately12 min,and the next goal is to ensure that the response time across Beijing does not exceed 12 min (the information comes from the Beijing Emergency Medical Center).
文摘Recently,numerous estimation issues have been solved due to the developments in data-driven artificial neural networks(ANN)and graph neural networks(GNN).The primary limitation of previous methodologies has been the dependence on data that can be structured in a grid format.However,physiological recordings often exhibit irregular and unordered patterns,posing a significant challenge in conceptualising them as matrices.As a result,GNNs which comprise interactive nodes connected by edges whose weights are defined by anatomical junctions or temporal relationships have received a lot of consideration by leveraging implicit data that exists in a biological system.Additionally,our study incorporates a structural GNN to effectively differentiate between different degrees of infection in both the left and right hemispheres of the brain.Subsequently,demographic data are included,and a multi-task learning architecture is devised,integrating classification and regression tasks.The trials used an authentic dataset,including 800 brain x-ray pictures,consisting of 560 instances classified as moderate cases and 240 instances classified as severe cases.Based on empirical evidence,our methodology demonstrates superior performance in classification,surpassing other comparison methods with a notable achievement of 92.27%in terms of area under the curve as well as a correlation coefficient of 0.62.
文摘Objective:To analyze the effectiveness of the matrix medical administration model in enhancing medical safety management.Method:A total of 39 medical incidents in the hospital from September 2020 to September 2022 were selected as the reference group,implementing conventional medical administration.Another 39 medical incidents from October 2022 to October 2024 were chosen as the experimental group,adopting the matrix medical administration model.The practical indicators such as causes of medical disputes,dispute compensation,medical injury appraisal results,and diagnosis and treatment quality indicators were compared between the two groups.Results:In the experimental group,the primary reasons for medical disputes were patient-related,and most disputes resulted in no compensation.After medical injury appraisal,most cases were not considered medical injuries.The comparison between the two groups was statistically significant(P<0.05).The diagnosis and treatment quality indicators of the experimental group were superior to those of the reference group(P<0.05).Conclusion:The matrix medical administration model can reduce medical disputes caused by hospital factors,decrease the proportion of compensation and the incidence of medical injuries,and improve the quality of diagnosis and treatment,demonstrating high management effectiveness.
