A SOA-Based Platform to Support Clinical Data Sharing
The eSource Data Interchange Group, part of the Clinical Data Interchange Standards Consortium, proposed five scenarios to guide stakeholders in the development of solutions for the capture of eSource data. The fifth scenario was subdivided into four tiers to adapt the functionality of electronic health records to support clinical research. In order to develop a system belonging to the \u201cInteroperable\u201d Tier, the authors decided to adopt the service-oriented architecture paradigm to support technical interoperability, Health Level Seven Version 3 messages combined with LOINC (Logical Observation Identifiers Names and Codes) vocabulary to ensure semantic interoperability, and Healthcare Services Specification Project standards to provide process interoperability. The developed architecture enhances the integration between patient-care practice and medical research, allowing clinical data sharing between two hospital information systems and four clinical data management systems/clinical registries. The core is formed by a set of standardized cloud services connected through standardized interfaces, involving client applications. The system was approved by a medical staff, since it reduces the workload for the management of clinical trials. Although this architecture can realize the \u201cInteroperable\u201d Tier, the current solution actually covers the \u201cConnected\u201d Tier, due to local hospital policy restrictions
Detecting of a Patient's Condition From Clinical Narratives Using Natural Language Representation
The rapid progress in clinical data management systems and artificial
intelligence approaches enable the era of personalized medicine. Intensive care
units (ICUs) are the ideal clinical research environment for such development
because they collect many clinical data and are highly computerized
environments. We designed a retrospective clinical study on a prospective ICU
database using clinical natural language to help in the early diagnosis of
heart failure in critically ill children. The methodology consisted of
empirical experiments of a learning algorithm to learn the hidden
interpretation and presentation of the French clinical note data. This study
included 1386 patients' clinical notes with 5444 single lines of notes. There
were 1941 positive cases (36 % of total) and 3503 negative cases classified by
two independent physicians using a standardized approach. The multilayer
perceptron neural network outperforms other discriminative and generative
classifiers. Consequently, the proposed framework yields an overall
classification performance with 89 % accuracy, 88 % recall, and 89 % precision.
Furthermore, a generative autoencoder learning algorithm was proposed to
leverage the sparsity reduction that achieved 91% accuracy, 91% recall, and 91%
precision. This study successfully applied learning representation and machine
learning algorithms to detect heart failure from clinical natural language in a
single French institution. Further work is needed to use the same methodology
in other institutions and other languages.Comment: Submitting to IEEE Transactions on Biomedical Engineering. arXiv

A novel data management platform to improve image-guided precision preclinical biological research
Objective: Preclinical biological research is mandatory for developing new drugs to investigate the toxicity and efficacy of the drug. In this paper, the focus is on radiobiological research as an example of advanced preclinical biological research. In radiobiology, recent technological advances have produced novel research platforms which can precisely irradiate targets in animals and use advanced onboard image-guidance, mimicking the clinical radiotherapy environment. These platforms greatly facilitate complex research combining several agents simultaneously (in our example, radiation and non-radiation agents). Since these modern platform can produce a large amount of wide-ranging data, one of the main impediments in preclinical research platforms is a proper data management system for preclinical studies. Methods: A preclinical data management system, inspired by current radiotherapy clinical data management systems was designed. The system was designed with InterSystems technology, i.e. a programmable Enterprise Service Bus solution. New DICOM animal imaging standards are used such as DICOM suppl. 187 for storing small animal acquisition context and the DICOM second generation course model. Results: A small animal big data warehouse environment for research is designed to work with modern image-guided precision research platforms. Its modular design includes (1) a study workflow manager, (2) a data manager, and (3) a storage manager. The system provides interfaces to, e.g. preclinical treatment planning systems and data analysis plug-ins, and guides the user efficiently through the many steps involved in preclinical research. The system manages various data source locations, and arranges access to the data centrally. Conclusion: A novel preclinical data management system can be designed to improve preclinical workflow, facilitate data exchange between researchers, and support translation to clinical trials. Advances in knowledge: A preclinical data management system such as the one proposed here would greatly benefit preparation, execution and analysis of biological experiments, and will eventually facilitate translation to clinical trials
The Integrated Proactive Surveillance System for Prostate Cancer
In this paper, we present the design and implementation of the integrated proactive surveillance system for prostate cancer (PASS-PC). The integrated PASS-PC is a multi-institutional web-based system aimed at collecting a variety of data on prostate cancer patients in a standardized and efficient way. The integrated PASS-PC was commissioned by the Prostate Cancer Foundation (PCF) and built through the joint of efforts by a group of experts in medical oncology, genetics, pathology, nutrition, and cancer research informatics. Their main goal is facilitating the efficient and uniform collection of critical demographic, lifestyle, nutritional, dietary and clinical information to be used in developing new strategies in diagnosing, preventing and treating prostate cancer
Clinical Trial Data Management in Environmental Health Tailored for an African Setting
Clinical trial data management tools are widely available—some free to access and
others relatively expensive, particularly for low- and middle-income countries. Such tools also do
not always permit adaptation for local conditions nor include options to capture environmental
and meteorological data. In the context of climate change and pressing environmental health
threats, more studies that aim to assess the impacts of environmental change on public health
are being carried out. Here, using freely available software, we tailor-made a clinical trial data
management tool that managed all aspects of an intervention-based clinical trial to assess the impact
of personal solar ultraviolet radiation exposure on vaccine e ectiveness. Data captured and associated
procedures included patient data, scheduling, reporting, analysis and data management. Moreover,
patient enrolment, recruitment, follow-up and decision-making in response to patient data were
managed. Given the multidisciplinary study approach, the tool also managed all environmental
and meteorological data for the rural African study site. Application of the tool ensured e cient
communication between rural sites, a relatively high overall participant response rate (87%) and
minimal loss to follow-up. This study suggests that it is possible to tailor-make a clinical trial data
management tool for environmental and public health studies.The National Research Foundation

The Role of Practice Research Networks (PRN) in the Development and Implementation of Evidence: The Northern Improving Access to Psychological Therapies PRN Case Study
Practice research networks (PRNs) can support the implementation of evidence based practice in routine services and generate practice based evidence. This paper describes the structure, processes and learning from a new PRN in the Improving Access to Psychological Therapies programme in England, in relation to an implementation framework and using one study as a case example. Challenges related to: ethics and governance processes; communications with multiple stakeholders; competing time pressures and linking outcome data. Enablers included: early tangible outputs and impact; a collaborative approach; engaging with local research leads; clarity of processes; effective dissemination; and committed leadership
