ABSTRACT
As a consequence of the global pandemic, many restrictions and rules were enforced. One predicament was the travel restrictions and requirements put into place with regard to vaccinations. Countries worldwide now require people to be vaccinated upon entry. The process of validating vaccine doses requires lots of paperwork and is inefficient. Blockchain is an uprising technology that is secure and fast at carrying out transactions. We propose implementing vaccine dose verifications between countries through vaccine certificates using Blockchain as an effective solution. The need for a common shared database, avoiding a trusted third party to administrate the network, having several countries involved, ensuring privacy and security, and accountability logs make Blockchain needed in this scenario. Digital vaccine certificates are very sensitive information that must be kept private and secure but accessible to several entities. Blockchain ensures the aforementioned requirements are met while preserving the integrity of the VDCs. This paper describes blockchain technology and its application in digital vaccine certificates. © 2022 IEEE.
ABSTRACT
Introduction: COVID-19 has drastically transformed healthcare delivery and forced many to utilize telehealth. This study aimed to comprehensively evaluate the telehealth service "Sehha" used during COVID-19 in Saudi Arabia and assess the provider experience and satisfaction with Sehha. Methods: A questionnaire was distributed by the Ministry of Health (MoH) to 362 physicians using Sehha. The questionnaire items were adapted from previous studies and then tested for content validity and reliability (alpha = 0.88). Results: The findings showed that most of the physicians improved their experience in telehealth because of COVID-19. The majority of the physicians (67.6 percent) reported being satisfied with Sehha. However, the most commonly perceived challenge by the physicians was difficulty in providing accurate medical assessments. Conclusion: COVID-19 has remarkably uncovered numerous benefits of telehealth. Therefore, telehealth should remain a permanent model of healthcare delivery with consideration of further telehealth development initiatives.
