Sdhcare: Secured Distributed Healthcare System
In the healthcare sector, the move towards Electronic Health Records (EHR) systems has been accelerating in parallel with the increased adoption of IoT and smart devices. This is driven by the anticipated advantages for patients and healthcare providers. The integration of EHR and IoT makes it highly heterogeneous in terms of devices, network standards, platforms, types of data, connectivity, etc. Additionally, it introduces security, patient and data privacy, and trust challenges. To address such challenges, this thesis proposes an architecture that combines biometric-based blockchain technology with the EHR system. More specifically, this thesis describes a mechanism that uses a patient’s fingerprint for recovery of patient’s access control on their EHRs securely without compromising their privacy and identity. A secure distributed healthcare system (SDHCARE) is proposed to uniquely identify patients, enable them to control access to, and ensure recoverable access to their EHRs that are exchanged and synchronized between distributed healthcare providers. The system takes into account the security and privacy requirements of Health Insurance Portability and Accountability Act (HIPAA) compliance, and it overcomes the challenges of using secret keys as a patient’s identity to control access to EHRs. The system used distributed architecture with two layers being local to each healthcare provider that is a member of SDHCARE, and two layers shared across all members of SDCHARE system. SDHCARE system was prototyped and implemented in order to validate its functional requirements, security requirements, and to evaluate its performance. The results indicated successful fulfillment of design requirements without significant overhead on the performance as required by healthcare environment
Impact of Mobile and Wireless Technology on Healthcare Delivery services
Modern healthcare delivery services embrace the use of leading edge technologies and new
scientific discoveries to enable better cures for diseases and better means to enable early
detection of most life-threatening diseases. The healthcare industry is finding itself in a
state of turbulence and flux. The major innovations lie with the use of information
technologies and particularly, the adoption of mobile and wireless applications in
healthcare delivery [1]. Wireless devices are becoming increasingly popular across the
healthcare field, enabling caregivers to review patient records and test results, enter
diagnosis information during patient visits and consult drug formularies, all without the
need for a wired network connection [2]. A pioneering medical-grade, wireless
infrastructure supports complete mobility throughout the full continuum of healthcare
delivery. It facilitates the accurate collection and the immediate dissemination of patient
information to physicians and other healthcare care professionals at the time of clinical
decision-making, thereby ensuring timely, safe, and effective patient care. This paper
investigates the wireless technologies that can be used for medical applications, and the
effectiveness of such wireless solutions in a healthcare environment. It discusses challenges
encountered; and concludes by providing recommendations on policies and standards for
the use of such technologies within hospitals
Barriers to the adoption of health information technology
Information Technology (IT) is successfully applied in a diverse range of fields. Though, the field of Medical Informatics is more than three decades old, it shows a very slow progress compared to many other fields in which the application of IT is growing rapidly. The spending on IT in health care is shooting up but the road to successful use of IT in health care has not been easy. This paper discusses about the barriers to the successful adoption of information technology in clinical environments and outlines the different approaches used by various countries and organisations to tackle the issues successfully. Investing financial and other resources to overcome the barriers for successful adoption of HIT is highly important to realise the dream of a future healthcare system with each customer having secure, private Electronic Health Record (EHR) that is available whenever and wherever needed, enabling the highest degree of coordinated medical care based on the latest medical knowledge and evidence. Arguably, the paper reviews barriers to HIT from organisations’ alignment in respect to the leadership; with their stated values when accepting or willingness to consider the HIT as a determinant factor on their decision-making processes. However, the review concludes that there are many aspects of the organisational accountability and readiness to agree to the technology implementation

A conceptual model for EAI adoption in an e-government environment
The non-integrated nature of Local Government Authority (LGA) Information Systems (IS) is
strongly associated with the inconsistency and duplication of data, reduction in data integrity and
quality, and high operational and maintenance cost. The reason is that legacy IS within the LGAs
are usually tailored to support particular business processes and functions and are as a
consequence usually difficult to integrate. This gives rise to a strong need for an integrated
architecture that facilitates reuse of existing applications and flexibly implementing business
processes across the functional boundaries within the LGAs. This paper examines a potentially
important area of IS integration in the United Kingdom (UK) LGAs through Enterprise
Application Integration (EAI) technology. A review of the literature indicates that EAI has been a
focal technology for several organisations in solving their integration problems. However, is new
in the LGAs; thus research literature around it is limited. Yet the effect of IS integration using
EAI technology remains under explored, as little research has been conducted to comprehend the
LGAs perception of integration that influences their decisions and actions. The author
demonstrates that it is of high importance to investigate this area within LGAs and result in
research that contributes towards successful EAI adoption. Therefore, resulting in the
development of a conceptual model that may be used to assist the government decision-making
process for EAI adoption in an electronic Government (e-Government) environment

A conceptual model of enterprise application integration in higher education institutions
Copyright @ 2013 EMCIS.It is eminent that several applications’ systems are deployed at different levels in Higher Education (HE), ranging from academic and administrative to staff and students record systems. Many of these systems suffer from different problems due to the lack of integration such as data redundancy, inconsistency and maintenance cost. Enterprise Application Integration (EAI) can provide substantial benefits to these systems, such as assisting with business process integration, facilitating e-service based transformation and supporting collaborative decision-making. However, some factors that influence EAI adoption process in HE will be defined. This paper introduces a conceptual model to explain the outcome of using EAI in Higher Education Institutions (HEIs). Analyzing the combination of the existing classification of EAI factors with the HE factors will enhance the implementation of EAI in HEI at both organizational and operational levels. A pilot study at King Abdulaziz University (KAU), Kingdom of Saudi Arabia will be presented in this paper to show that the integration of the multiple information systems gives an integrated view to facilitate information access and reuse. Moreover data from different information systems is combined to gain a more comprehensive basis to satisfy the educational needs
Wireless technology and clinical influences in healthcare setting: an Indian case study
This chapter argues that current techniques used in the domain of Information Systems is not adequate for establishing determinants of wireless technology in a clinical setting. Using data collected from India, this chapter conducted a first order regrssion modeling (factor analysis) and then a second order regression modeling (SEM) to establish the determinants of clinical influences as a result of using wireless technology in healthcare settings. As information systems professionals, the authors conducted a qualitative data collection to understand the domain prior to employing a quantitative technique, thus providing rigour as well as personal relevance. The outcomes of this study has clearly established that there are a number of influences such as the organisational factors in determining the technology acceptance and provides evidence that trivial factors such as perceived ease of use and perceived usefulness are no longer acceptable as the factors of technology acceptance

Designing privacy for scalable electronic healthcare linkage
A unified electronic health record (EHR) has potentially immeasurable benefits to society, and the current healthcare industry drive to create a single EHR reflects this. However, adoption is slow due to two major factors: the disparate nature of data and storage facilities of current healthcare systems and the security ramifications of accessing and using that data and concerns about potential misuse of that data. To attempt to address these issues this paper presents the VANGUARD (Virtual ANonymisation Grid for Unified Access of Remote Data) system which supports adaptive security-oriented linkage of disparate clinical data-sets to support a variety of virtual EHRs avoiding the need for a single schematic standard and natural concerns of data owners and other stakeholders on data access and usage. VANGUARD has been designed explicit with security in mind and supports clear delineation of roles for data linkage and usage
