ABSTRACT
COVID-19 has become a very transmissible disease that has had a worldwide impact, resulting in a huge number of infections and fatalities. Testing is critical to the pandemic's successful response because it helps detect illnesses and so attenuate (isolate/cure) them and now vaccination is a life-safer innovation against the pandemic which helps to make the immunity system stronger and fight against this infection. Patient-sensitive information, on the other hand, is now held in a centralized or third-party storage paradigm, according to COVID-19. One of the most difficult aspects of using a centralized storage strategy is maintaining patient privacy and system transparency. The application of blockchain technology to support health initiatives that can minimize the spread of COVID-19 infections in the context of accessibility of the system and for verification of digital passports. Only by combining blockchain technology with advanced cryptographic algorithms can a secure and privacy-preserving solution to COVID-19 be provided. In this article, we investigate the issue and propose a blockchain-based solution incorporating conscience identity, encryption, and decentralized storage via interplanetary file systems (IPFS). For COVID-19 test takers and vaccination takers, our solution includes digital health passports (DHP) as a certification of test or vaccination. We explain smart contracts constructed and tested with Ethereum to preserve a DHP for test and vaccine takers, allowing for a prompt and trustworthy response from the necessary medical authorities. We use an immutable trustworthy blockchain to minimize medical facility response times, relieve the transmission of incorrect information, and stop the illness from spreading via DHP. We give a detailed explanation of the proposed solution's system model, development, and assessment in terms of cost and security. Finally, we put the suggested framework to the test by deploying a smart contract prototype on the Ethereum TESTNET network in a Windows environment. The study's findings revealed that the suggested method is effective and feasible.
ABSTRACT
Purpose: Telehealth, Internet interventions, or digital apps provide healthcare to isolated regions and can span borders. The purpose of this research was to assess the use of the Seha application, public perceptions toward the application, and factors that affect its utilization. Methods: The cross-sectional method was used to analyze the quantitative data. Grounded Theory was used to analyze the qualitative data. This study was conducted from December 1, 2018, to January 31, 2019. A total of 419 participants were surveyed online, and semi-structured interviews were conducted for 20 participants. The participants were chosen based on convenience sampling techniques. The survey contained two sections. The first section consisted of demographic data and the second section included eight questions, each covering one main aspect. For the qualitative approach, participants were chosen using a theoretical sampling technique. Researchers acted as the primary data collection instrument. Results: Out of the total, 88.5% of the participants did not use "Seha" application. Among users, the main perceived benefit from the application was the ability to contact a general practitioner anytime. Among non-users, the greatest barrier to use was the lack of awareness about it, while the ability to contact a general practitioner any time (25%) and reducing visits to the doctor (23%) were the top motivations. A conceptual framework was developed to define the different aspects affecting the use of the online medical consultation application. These aspects included awareness and education, technical issues, access, and consultation information. Conclusion: Public awareness and education about the application, as well as the integration of its functions with other healthcare systems were the main recommendations suggested. Implementing these recommendations is encouraged to deliver value to e-health initiatives in Saudi Arabia.
