In a permissioned environment, users’ identities are known and lesser chances exist for users to perform any malicious activities. The implementation on HyperLedger uses the PBFT consensus mechanism. Data is stored in two data stores, locally in the clinic associated with the medical record and another set of the organized patients’ data in the cloud, encrypted with the patients’ secret key. The framework ensures the following features, privacy, security, availability, and scalability. Privacy is provided by allowing a patient complete control over the access control policy over his/her data. Security attacks aren’t very plausible since the network is permissioned and the identities of every user is known. With cloud-based storage and APIs, availability of data is also ensured. Scalability is ensured by the PBFT consensus protocol. However, the paper seems to target only one kind of medical record as mentioned and in future efforts, the authors will work on including more kinds of medical records, including images.

The HIS also improves the health status, which supports the continuity of care and focuses on wellness and empowerment of the individuals’ and community responsibility for health [17]. Reduction in transcription error and duplication of information entries are the benefits of the implementation of HIS in hospital. HIS implementation also leads to improved monitoring of drug usage [7]. The HIS is known to enhance the efficacy and productivity of patient services in healthcare organization. From the HIS implementation, a good relationship between patients and healthcare providers is enhanced, which creates a greater mutual understanding, trust, and satisfaction of patients. This relation will enhance an effective communication, which leads to a more efficient chronic disease care, and higher quality of physical health and life [18].
A cloud computing solution for medical institutions
Published in Amir Hussain, Mirjana Ivanovic, Electronics, Communications and Networks IV, 2015
The Information System in Hospital (HIS) is a means for the software system which is used in clinical medicine management and the financial management of the hospital. It manages the operation of all departments and equipments (Cao & Wang 2013). HIS consists of Electronic Medical Record (EMR), Laboratory Information System (LIS), Anesthesia Information Management System (AIMS), Nosocomial Infection Surveillance (NIS), Radiology Information System (RIS), and Physical Examination Information System (PEIS), etc. The HIS component which follows the health level 7 standards (HL7) is shown as Fig. 1.

The impact of IT implementation on organization performance has been widely studied. According to Lau et al. (2010), IT implementation has a positive relationship with IT utilization, and IT utilization is the mediator between IT implementation and performance. However, it is not conclusive in the context of healthcare information technology and HIS. In this study, we focus on three types of functionalities: CPOE, CCD, and EMRP. We examine the level of HIS implementation on hospital performance. H4: Hospital size moderates the relationship among IT implementation, service volume and performance.
Business continuity-inspired fuzzy risk assessment framework for hospital information systems

Healthcare organisations play a significant role in the community health. Many people die annually due to hospital errors (Yucel et al. 2012). Hospitals are one of the vital providers of healthcare services that are increasingly using ISs to reduce errors (Ash, Berg, and Coiera 2004). A hospital information system (HIS) is a customised IS which has a critical role to satisfy patients and other parties in a hospital (e.g. physicians and nurses). Because of recording vital patients’ data/information in HISs, their security issues are very important. Moreover, risk management of HISs is quite necessary due to the expansion of virtual world and technology.

The extent to which an innovation is perceived as better than its ancestor is called as a relative advantage [22]. Relative advantage may influence business; therefore, businesses are forced to adopt new technologies [49,54]. Operating costs of hospitals are concerned these days because of the increasing competition between hospitals. Thus, relative advantage is referred to the acquisition of HIS that help in reducing the operating cost of hospitals [16,55]. The intention of hospitals to adopt HIS is influenced by the relative advantage [27]. Improved HIS provides better patient care and enhances the efficiency of hospitals’ staff [50]. Therefore, the proposed hypothesis is as follows:Hypothesis 3: Relative advantage has a significant positive impact on HIS adoption. DOI theory defines compatibility as the degree to which an innovation is suitable according to the experience, value, and needs of the potential users [22]. An organization requires minimal changes and modifications in the presence of a high level of compatibility. Hence, IS adoption will be more receptive. Compatibility influences directly to the adoption of HIS. Advancement of technologies led to the availability of more complex systems like advanced hardware and software and highly developed networking system [46]. Nursing Information System, Pharmacy Information System, Radiology Information System, Clinical Information System, and Picture Archiving and Communication System are some examples of sub systems of HIS that are incorporated slowly into fully integrated systems [12,46]. However, a study conducted by [46] claimed that the adoption of HL7 in the hospital was incompatible with the existing IT infrastructure and networking system. Moreover, HL7 was complex with the capabilities of the IT staff. Therefore, one of the important factors is the level of compatibility in the technical dimension. Hence, the proposed hypothesis is as follows:Hypothesis 4: Compatibility has a positive impact on the adoption of HIS. The extent to which an IS innovation is taken as complex to understand and use is referred to as complexity [22]. Some organizations perceive that IS innovation as complex because of the shortage of required skills and competence of the staff [16,56]. Public hospitals face challenges because a number of patients belong to the various classes of the society when compared to private hospitals [12]. The complexity of innovation resists in adopting HIS due to the lack of perceived knowledge and skills [27]. Many studies concluded that insufficient knowledge and skills of medical practitioners are not looking forward to adopt this innovation. Thus, we proposed a hypothesis for HIS adoption.Hypothesis 5: Complexity of HIS has a negative impact on the adoption of HIS.
