The technological aspects include EPR implemented using Online Transaction Processing (OTP) using Internet and Internet based systems, more recently via Cloud- Based systems (CBS) exploiting Cloud Service Models (CSM). Additionally, there are many socio-political considerations comprising: (1) political moves, including UK Government policy, which aims to deliver for patients 27/7 online access to their patient record, (2) considerations around ethical issues and informed permission and acceptance by the public and non-governmental organizations (NGO), (3) technological considerations about identification of suitable CBS and data structures in distributed systems characterized by unstructured data and, finally (4) sharing and collaboration as means of increasing efficiency, security, privacy, etc. In all, the aim is to provide professionals in medical domain with advanced platforms to not only access but also most importantly to share and collaborate at a wide scale level (e.g. National level). Addressing these aspects of EPR requires collaboration between all stakeholders in EPR, this paper considers these and concludes that such collaboration is essential if EPR are ever to become a reality.Peer ReviewedPostprint (author's final draft

Data as a Service (DaaS) for sharing and processing of large data collections in the cloud

Data as a Service (DaaS) is among the latest kind of services being investigated in the Cloud computing community. The main aim of DaaS is to overcome limitations of state-of-the-art approaches in data technologies, according to which data is stored and accessed from repositories whose location is known and is relevant for sharing and processing. Besides limitations for the data sharing, current approaches also do not achieve to fully separate/decouple software services from data and thus impose limitations in inter-operability. In this paper we propose a DaaS approach for intelligent sharing and processing of large data collections with the aim of abstracting the data location (by making it relevant to the needs of sharing and accessing) and to fully decouple the data and its processing. The aim of our approach is to build a Cloud computing platform, offering DaaS to support large communities of users that need to share, access, and process the data for collectively building knowledge from data. We exemplify the approach from large data collections from health and biology domains.Peer ReviewedPostprint (author's final draft

LEVERAGING BLOCKCHAIN TECHNOLOGY FOR SLA ENFORCEMENT IN HEALTH CARE CLOUD PARTNERSHIPS

The healthcare industry is rapidly adopting cloud-based solutions to improve operational efficiency and patient outcomes. However, healthcare cloud partnerships often face challenges related to the lack of scalability, trust, and Service Level Agreement (SLA) enforcement, and has a notable impact on consumer care quality. To address this issue, the study proposed leveraging blockchain technology to enhance SLA enforcement by using smart contracts in health care cloud partnerships for small and medium-sized facilities. The research questions were: Q.1 What are the current challenges facing small to medium sized healthcare facilities in enforcing SLAs in cloud partnerships? Q.2 How can BC-based smart contracts helps enhance scalability in cloud computing systems in healthcare SMEs by enforcing Service Level Agreements (SLAs) in a safe and efficient manner? Q.3 What are the factors that affect the implementation of blockchain-based smart contracts for SLA enforcement in healthcare SMEs cloud partnerships? The project utilized case studies to demonstrate the effectiveness of using BC technology based smart contracts to enhance SLA enforcement and improve patient outcomes. The findings and conclusions were as follows: 1. Current challenges facing healthcare SMEs in enforcing SLAs in cloud partnerships: SMEs may lack bargaining power, resources, and technical expertise to effectively negotiate, monitor, and enforce SLAs in cloud partnerships, leading to service disruptions, compliance issues, and financial losses. 2. BC-based smart contracts can enhance the scalability of cloud computing systems in healthcare SMEs by automating SLA execution, ensuring real-time data integrity, transparency, and accountability, reducing fraud, error, and transaction costs, and enabling decentralized trust among stakeholders. 3. Factors affecting the implementation of BC-based smart contracts to better SLA enforcement in healthcare SMEs cloud partnerships: regulatory uncertainty, interoperability, standardization, privacy, security, cost, complexity, governance, and user adoption, and 4. Unique Trends and challenges in the healthcare industry for its data analysis: increasing demand for real-time, patient-centered, personalized, and evidence-based care, generating and integrating large volumes of diverse and complex data from multiple sources, ensuring data quality, privacy, and security, complying with regulations and standards, and fostering collaboration and innovation across stakeholders. MedRec, SimplyVital Health, and Medical Chain demonstrate how BC provides secure data sharing, encryption and access control mechanisms, and promotes interoperability through standard data formats and protocols. Results showed improved scalability, trust, and SLA enforcement with the use of BC technology. Further research in the other domains of this area is recommended. It is required to address broader aspects related to the topic. The areas for further study that emerged from the findings and conclusions of this project include: 1. interoperability,2. trusted monitoring solutions, 3.user experience, 4. privacy and security,5. med tokens, cost and 6. integration with existing BSS and OSS.

The OCareCloudS project: toward organizing care through trusted cloud services

The increasing elderly population and the shift from acute to chronic illness makes it difficult to care for people in hospitals and rest homes. Moreover, elderly people, if given a choice, want to stay at home as long as possible. In this article, the methodologies to develop a cloud-based semantic system, offering valuable information and knowledge-based services, are presented. The information and services are related to the different personal living hemispheres of the patient, namely the daily care-related needs, the social needs and the daily life assistance. Ontologies are used to facilitate the integration, analysis, aggregation and efficient use of all the available data in the cloud. By using an interdisciplinary research approach, where user researchers, (ontology) engineers, researchers and domain stakeholders are at the forefront, a platform can be developed of great added value for the patients that want to grow old in their own home and for their caregivers

Developing Predictive Molecular Maps of Human Disease through Community-based Modeling

The failure of biology to identify the molecular causes of disease has led to disappointment in the rate of development of new medicines. By combining the power of community-based modeling with broad access to large datasets on a platform that promotes reproducible analyses we can work towards more predictive molecular maps that can deliver better therapeutics
