Designing Framework of Cloud Health Record (CHR) System for Patient Health Information Storage: A New Prophecy

Patient health record system offers significant health care benefits to improve the quality of health amenities, it has been reducing alarm rate of failures in medicinal treatment. Medical records contain large volumes of aggregated and longitudinal clinical data that could insist patient safety. In order to minimize the cost, replication of records and infrastructure, the emerging technologies like server virtualization and cloud computing is unavoidable at present medical environment. Cloud technology facilitates data storage, that keeps for all time availability of every individual patient information. Storing and maintaining the patient information is very essential for the future reference by any other hospitals and medical experts. Cloud computing makes convenient to the other stake holders of healthcare environment such as pharmacist, nurses, lab technicians, physician and other specialists. Existing patient’s health records (PHR) maintained by manually and electronically (EHR) and stored in localized server controlled by hospital authority. In this article, we outlined new prophecy of Cloud based storing system called Cloud Health Record (CHR), we suggest that the new system will help to store huge volume of patient information and it will facilitate sharing the patient records on the cloud based system for getting further and better opinion from the physician, who lives anywhere. *Corresponding Author: Dr. Prakash Kuppuswamy, Department of CNET, College of Computer Science & Information Systems, Jazan University, KSA; E-mail: prakashcnet@gmail.com Citation: Kuppuswamy P, Sundaram S, John R (2020) Designing Framework of Cloud Health Record (CHR) System for Patient Health Information Storage: A New Prophecy.

in medical application can be development of patient records and information storing on the cloud. Cloud-based environment system can offer provides several advantages such as scalability, availability and mobility [4,[7][8][9][10], and there are some barriers that must also be managed [4,15,16]. Establishing Cloud-based EHR management system, the main advantage is the ability to share patient records with other clinical centers, and the integration of all the EHRs of a group of clinical centers in order to help medical staff perform their jobs [4,[17][18][19]. The reason for offering cloud computing technology in Patient health records, it provides basic infrastructure to hosting remotely the large volume of patient information and it can be accessed by anyone directly over the internet. The main objective of Health Records to support the maintenance of integrated, efficient and quality health [23,24]. To establish efficient cloud structure, we need following three services:

Introduction
Patient health record is a paper repository of information that was reviewed or used for clinical, research, administrative and other government purposes. Paper based records accessed by single user only at a time. Records should be update every time by manual operation, resulting in delays for record completion that lasted anywhere from one to six months or more. Paper based records can be accessed and view by many people without any authorization, its triggered no safety and privacy [5]. Health information technology is evolving very fast and has penetrated in human lives that now it is absorbed in the system in a more promptly [4]. Many healthcare facilities from across the globe have implemented EHR systems to improve the information recording process but only a few have been successful [2,9]. Cloud environment provided centralized storage of data and connected remote server and it provides various data service accessed by remotely. Simply cloud computing is the acquisition to computing resources through the Internet [24][25][26].
Cloud computing is a kind of new environment which facilitates in sharing the resources and services over the internet rather than having these services and resources on local servers/ nodes or personal devices [1]. Cloud technology providing service as according to the usage of service, and it has raised more expectations. The significant benefits of cloud deployment reducing storage and maintenance of infrastructure cost [4]. Cloud offers great opportunity for medical related application to connect their services not only promptly but also in new formats with the flexibilities such data storing, editing, modification, exchange, access from any places. Many hospitals are planning to build and their own data centers to storing the patient information for sharing the information to other hospitals or future references.
The new concept of cloud and patient health record has generated a new model called Patient cloud records. The usages of cloud computing may vary with the medical application such as nature, services and information needs but most common usages of cloud computing with Cloud technology enabling on-demand network access to shared pool of computing resources and accessible by anytime and anywhere. Therefore, the organization of National Institute of Standards and Technology (NIST) defines standard essential characteristics of cloud computing. This cloud computing model is composed of three service model, four deployment models and following six essential characteristics. 1. On-demand self-service: In this set up the resources are provided to the user on demand. The user has option to manage these computing resources.

Literature Review
Repu Daman, Manish Tripathi, Saroj Mishra (2016) discussed about using of mobile computing and cloud technology in healthcare domain. Maintaining the secrecy of patients' records and information is responsible of hospital management and that record helps the quality of treatment. The application of cloud computing reduces cost and all time availability of patient's record. In addition, authors elaborated about the advantage of cloud data access that can be available anywhere in the geographical region. They suggest hospitals and other healthcare providers need to adapt quickly to the cloud technologies and collaborate more efficient manner to improve the quality of service in health industry [4]. Elise Russo, Dean F. Sittig, Daniel R. Murphy, Hardeep Singh (2016) Electronic health record (EHR) data storage consist huge volume of data. Keeping patient information or data safety successes by few software model. In this research article author analyzed with a model of missed/delayed follow-up of test results to discuss realworld challenges in using EHR data for patient safety research. The output of the research brought three types of challenges that pose as barriers to advance patient safety improvement. Author identifies problems of existing health record maintenance. Health records and their abundant data for patient safety improvement research, many current data access and security policies and procedures must be rewritten and standardized across health care organizations [6].
Ebru Celikel Cankaya, Than Kywe, (2015) In this article author prosed comprehensive electronic health record system based on AES encryption standard. Proposed database model using as a software engineering approach and database development model and combine the two to present a guideline to design and develop other similar projects. Data based model design with ER model and using 3 NF normalized form. This proposed model can be extending design to provide an interactive tool that will help user get involved actively in the design process [7].
Pradeep Deshmukh (2017) Discussed about significance of health care system used by its stake holder of healthcare user such as nurses, specialists and patient. Cloud provide low cost and flexible to save patient health records with data privacy. Author proposed frame work of saving the health records and provides the accessibility to the physicians, patients and other healthcare users by providing accessible key. It provides the security to the health records with data encryption and stored data. Proposed model integrate rural and urban health care centers and hence more appropriate for health care services. The experimental result shows that it has a capability of scaling more number of records with effective safety and security [8].
Jaillah Mae Gesulgaa, Almarie Berjameb, Kristelle Sheen Moquialac (2017) Moreover, this article reviews and identifies barriers of EHR system. Authors proposed structured model of health record system. It's identifies problems of Health record system depends on user's lack of education and training, and concerns arising from data security were the predominant barriers recognized from the analyzed papers. In addition to that, author directed to examine the barriers in detail and recognize [9]. Everleen Wanyonyi, Anthony Rodrigues, Silvance Abeka, Solomon Ogara (2017) This study focused on the EHR security and threats. Author took sample questionnaire designed for qualitative data collection. This research article identified controlling and securing patient health record not possible by single control system. The system required physical security and software security and technical and administrative controls. The study established the effect of availability of resources and organizational culture on EHR information security, though most of the characteristics or factors of the two moderating variables were already covered in the predictor variables and therefore were not analyzed separately [10].

Significance of Research
Adoption of advance technology such as Cloud computing, Mobile computing and Big data analytics is far behind in Medical and applied medical sector. Primary work of healthcare institutions and hospitals depends on patient health records such as medical prescription and reports in a form of film-based radiological & pathological images, handwritten patient diagnosis and patient history etc., Collecting and keeping the above information and records are very tedious work for the Medical Record Department. The collaboration with the other hospitals and intra-communication between different departments, wards and Outpatient clinics are really challenging task. Customary Medical Record system requires entire infrastructure to storing and arranging data and it requires manpower to collecting information. Unified computing model is a vendor-designed system, more cost and centrally managed by the data centre and it is suitable for only big size hospital.
Medical practitioner is looking an integrated health records of patient that will provide a global and complete opinion of a patient health history that can lead to a better decision support by physicians during medical emergency or general consultation. Existing Grid computing based virtual environment also supports to store the large volume of data. But, it causes great pressure on the Electronic Health record server; also it leads transmission delays due to the network traffic. There may be a possibility of data delays or data loss due to the physical network accessories can have serious consequences that cannot be measured. Cloud based health record system has a significant change in providing healthcare information, reducing errors and increasing impact of health care. Accessing of patient history may provide better treatment and it improves more patient safety.

Proposed Structure and Implementation Plan
Keeping large volume of electronic information such as documents, images, emails, videos in organizations produce is staggering. Moreover, storing all your digital data in your data center can be expensive. Cloud storage supports to solve the above said problems with nominal maintenance cost. Internet providing facility of connecting cloud user can access and update data from anywhere and anyplace. It supports easy handling and storing patient information on remote networks.
This study aimed to enhance the facility of better administration and access of patient health information through the cloud storage. Existing storage system is not fulfilling the objective and effectiveness of patient health information on cloud storage. In general, the health care services are divided as Urban Health center, Rural Health Centers and Primary Health centers. Comparing to City and Rural, primary health services will be very basic and less advanced. The treatment with specialized health services in physician and equipment point of view will not be available in most parts of the rural and primary area. The significant advantage of implementing Cloud Heal Records (CHR) are connecting Primary Health Center, Rural Health center and Urban Health center directly through cloud medical server and it will be providing better service to patient. Proposed system architecture showed in figure 1, we are trying to provide complete and better utilization of cloud model patient health record system and privacy. The proposed method authorization given to many clinical persons to enter and update patient information. Cloud Health Records (CHR) segregated into patient details consist basic information of individual person. and next patient history consist of previous health issue details of patient and third one consist of sensitive information such as cancer, HIV and similar disease history. CHR transactions are conducting through central hub is called Cloud Data server and its controlled by Cloud administrator. The Centre hub of Cloud Data storage access granting by the cloud administrator to Physician, Clinical Lab, Pharmacy, other department, other hospital, patient and government for upload records and updating information. All above users/patients can enter their own personal health record data in this database. The CHR database consists of a vast number of patient health care records containing sensitive information. The technical part of cloud administration controls uses software and data to monitor and control access to information and computing systems. Responsibility of cloud administrator controls include passwords, firewalls, network intrusion detection systems, access control lists and data privacy.

Responsibility of Cloud Administrator
Cloud administrator works defined as management controls of written policies, procedures, standards and guidelines etc., Cloud Administrator controls inform users on how the data is to be access, save and protect the sensitive data. Cloud admin has to follow government laws and regulation, hospital policy, hiring policy, password policy and disciplinary policy etc., The significant work of Cloud Health Records mentioned in the above figure to controls patient basic information, patient history and sensitive information maintenance. The summarized points mentioned below: Medical Report Delivery Service: Cloud computing can be used for medical report delivery service to the patients at their home through mobile service. Performance: CHR services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a sharing medical resources effectively. Reliability: CHR system provide the facility of data backup, disaster recovery services at multiple redundant sites on the cloud network.

Comparison Analysis
Different scenarios involve medical records, but with one differenceone type is considered paper medical records, Electronic Medical Records, Electronic Health Records. Paper records require additional personnel to handle and support paper files and to organize countless documents. Other modern health record comparison mentioned in the below table 1.
Digitalization of records can save emergency care providers time during a patient's visit. One of the most obvious benefits of going digital is the reduction of adverse environmental impacts, Cloud based health record system provides numerous cybersecurity and data breaches. It's trying to reduce human administrative costs and storage costs. Sharing patient's data is much easier; patients and medical personnel can access information via an app or by sending a photo via a secured network. Cloud based record management costs by reducing on premise hardware and software management, simplifying monitoring, and reducing the need for extensive capacity planning. Many cloud storage service provided the facility of keeping multiple copies of patient data, and offer great object durability to avoid data loss.

Conclusion
Technology is advancing at a phenomenal rate, but it needs to be harnessed in the most efficient way. Cloud technology, resulting in cloud health records will certainly provide a great leap forward in providing access to large quantities of information to users. Cloud providing huge volume of data storage service to keep various data scheme such as document, image, gif and videos. Currently, standard and specific cloud application available in the market, it is provided by many cloud service companies. Some of the well-known cloud services are drop box, Sugar Sync, Apple iCloud, Google Drive, Microsoft OneDrive etc., Standard cloud service offers real-time document co-editing and these products even double as collaboration software. Proposed Cloud Health Record facilitates various services such as backup of health details and keeping availability of records in-order to any disk failures. Backup services always safer and it is accessible by only cloud administrator. Cloud health record service can extend and access from all geographical location. The proposed structure model is giving suggestion to improve the patient health information to store and accessibility through Cloud environment. This work is an initiation of organizing patient information on Cloud based storage in such a manner and it can be extending in future work with security aspects of the records.
