A perspective on the Healthgrid initiative
This paper presents a perspective on the Healthgrid initiative which involves
European projects deploying pioneering applications of grid technology in the
health sector. In the last couple of years, several grid projects have been
funded on health related issues at national and European levels. A crucial
issue is to maximize their cross fertilization in the context of an environment
where data of medical interest can be stored and made easily available to the
different actors in healthcare, physicians, healthcare centres and
administrations, and of course the citizens. The Healthgrid initiative,
represented by the Healthgrid association (http://www.healthgrid.org), was
initiated to bring the necessary long term continuity, to reinforce and promote
awareness of the possibilities and advantages linked to the deployment of GRID
technologies in health. Technologies to address the specific requirements for
medical applications are under development. Results from the DataGrid and other
projects are given as examples of early applications.Comment: 6 pages, 1 figure. Accepted by the Second International Workshop on

Suicide risk assessment in the emergency department:an investigation of current practice in Scotland
Background: Suicide is a global public health issue. Approximately one third of individuals who complete suicide have attended an emergency department in the year preceding their death. The aim of this study was to investigate current suicide risk assessment practices across emergency department clinicians in Scotland.Methods: A mixedâmethods design was employed. A total of 112 surveys for emergency department clinicians were posted to 23 emergency departments in Scotland between March and September 2016. Followâup semiâstructured interviews were also conducted exploring clinician's experiences of suicide risk assessment. Interviews were analysed using thematic analysis.Results: Fiftyâone emergency department clinicians across 17 emergency departments completed the survey. Thirtyâfive (68.6%) participants were currently using a suicide risk assessment tool; with most using locally developed tools and proformas (n = 20, 62.5%) or the SAD PERSONS scale (n = 13, 40.6%). Remaining participants (n = 16, 31.4%) did not use suicide risk assessment tools during assessment. Variation in practice was found both across and within emergency departments. Six clinicians participated in followâup interviews, which identified four major themes: Clinician Experiences of Suicide Risk Assessment; Components of Suicide Risk Assessment; Clinical DecisionâMaking; and Supporting Clinicians.Conclusions: There is substantial variation in current practice, with around twoâthirds of clinicians using a variety of empirically and locally developed tools, and a third using their judgement alone. Clinicians find suicide risk assessment a challenging part of their role and discuss the need for increased training, and appropriate and helpful guidelines to improve practice
XML for Domain Viewpoints
Within research institutions like CERN (European Organization for Nuclear
Research) there are often disparate databases (different in format, type and
structure) that users need to access in a domain-specific manner. Users may
want to access a simple unit of information without having to understand detail
of the underlying schema or they may want to access the same information from
several different sources. It is neither desirable nor feasible to require
users to have knowledge of these schemas. Instead it would be advantageous if a
user could query these sources using his or her own domain models and
abstractions of the data. This paper describes the basis of an XML (eXtended
Markup Language) framework that provides this functionality and is currently
being developed at CERN. The goal of the first prototype was to explore the
possibilities of XML for data integration and model management. It shows how
XML can be used to integrate data sources. The framework is not only applicable
to CERN data sources but other environments too.Comment: 9 pages, 6 figures, conference report from SCI'2001 Multiconference

Grid Databases for Shared Image Analysis in the MammoGrid Project
The MammoGrid project aims to prove that Grid infrastructures can be used for
collaborative clinical analysis of database-resident but geographically
distributed medical images. This requires: a) the provision of a
clinician-facing front-end workstation and b) the ability to service real-world
clinician queries across a distributed and federated database. The MammoGrid
project will prove the viability of the Grid by harnessing its power to enable
radiologists from geographically dispersed hospitals to share standardized
mammograms, to compare diagnoses (with and without computer aided detection of
tumours) and to perform sophisticated epidemiological studies across national
boundaries. This paper outlines the approach taken in MammoGrid to seamlessly
connect radiologist workstations across a Grid using an "information
infrastructure" and a DICOM-compliant object model residing in multiple
distributed data stores in Italy and the UKComment: 10 pages, 5 figure
