Background: The use of social media platforms to seek information continues to increase. Social media platforms can be used to disseminate important information to people worldwide instantaneously. However, their viral nature also makes it easy to share misinformation, disinformation, unverified information, and fake news. The unprecedented reliance on social media platforms to seek information during the COVID-19 pandemic was accompanied by increased incidents of misinformation and disinformation. Consequently, there was an increase in the number of scientific publications related to the role of social media in disseminating health misinformation and disinformation at the height of the COVID-19 pandemic. Health misinformation and disinformation, especially in periods of global public health disasters, can lead to the erosion of trust in policy makers at best and fatal consequences at worst. Objective: This paper reports a bibliometric analysis aimed at investigating the evolution of research publications related to the role of social media as a driver of health misinformation and disinformation since the start of the COVID-19 pandemic. Additionally, this study aimed to identify the top trending keywords, niche topics, authors, and publishers for publishing papers related to the current research, as well as the global collaboration between authors on topics related to the role of social media in health misinformation and disinformation since the start of the COVID-19 pandemic. Methods: The Scopus database was accessed on June 8, 2023, using a combination of Medical Subject Heading and author-defined terms to create the following search phrases that targeted the title, abstract, and keyword fields: (“Health*” OR “Medical”) AND (“Misinformation” OR “Disinformation” OR “Fake News”) AND (“Social media” OR “Twitter” OR “Facebook” OR “YouTube” OR “WhatsApp” OR “Instagram” OR “TikTok”) AND (“Pandemic*” OR “Corona*” OR “Covid*”). A total of 943 research papers published between 2020 and June 2023 were analyzed using Microsoft Excel (Microsoft Corporation), VOSviewer (Centre for Science and Technology Studies, Leiden University), and the Biblioshiny package in Bibliometrix (K-Synth Srl) for RStudio (Posit, PBC). Results: The highest number of publications was from 2022 (387/943, 41%). Most publications (725/943, 76.9%) were articles. JMIR published the most research papers (54/943, 5.7%). Authors from the United States collaborated the most, with 311 coauthored research papers. The keywords “Covid-19,” “social media,” and “misinformation” were the top 3 trending keywords, whereas “learning systems,” “learning models,” and “learning algorithms” were revealed as the niche topics on the role of social media in health misinformation and disinformation during the COVID-19 outbreak. Conclusions: Collaborations between authors can increase their productivity and citation counts. Niche topics such as “learning systems,” “learning models,” and “learning algorithms” could be exploited by researchers in future studies to analyze the influence of social media on health misinformation and disinformation during periods of global public health emergencies.

The preservation of knowledge is a universal requirement for every organisation that strives to gain a competitive advantage. Knowledge management systems are a modern business enabler and driver of success. Furthermore, the implementation of knowledge management systems is a comprehensive process which integrates people, business processes, the business universe, technology, and customers. However, some evidence suggests that organisations are investing a multiplicity of resources in implementing knowledge management systems with little success. Therefore, the aim of this study is to identify and understand the types of frameworks available for implementing knowledge management systems and present a comprehensive implementation framework including the relevant critical success factors and measurement tools that organisations may use for implementing knowledge management system projects. The successful implementation of knowledge management systems lie in the adoption of a suitable strategy and well-defined framework.

The resilience and reliability of healthcare supply chain models were put to the test by the Corona Virus Disease 2019 (COVID-19). This study investigated the application of supply chain systems in South African healthcare institutions during the COVID-19 pandemic. A systematic literature review (SLR) was employed to explore the performance of existing supply chain systems, followed by a case study that tested and compared the acquisition and distribution of COVID-19 resources. The SLR revealed that most of the flare-ups were exacerbated by the acquisition of insufficient resources and speculative shortages as the supply chain systems got overwhelmed by the unprecedented demand. The simulation of the real-world data of South Africa revealed gaps in the distribution of resources, allocation of medical staff to administer COVID-19 vaccines, and shortages of vaccines. The study recommends development of effective contextual (SA) healthcare supply chain systems to support the containment of pandemic flare-ups. The study was conducted in South Africa and only reported data was used.

Computer-based knowledge management systems provide sustainable management of organisational knowledge. The adoption of computer-based knowledge management systems assists organisations in harmonizing critical knowledge pertaining to their business procedures, and processes to effectively collaborate, reuse, and coordinate their efforts. However, available studies show that the implementation of computer-based knowledge management systems is problematic across a multitude of organisations, especially those in the healthcare sector. In this study, a framework and assessment tool were developed to enable healthcare organisations implement computer-based knowledge management systems successfully. The framework and assessment tool developed were tested as a proof of concept and the evaluation was done by two healthcare knowledge management executives and two industry experts. The framework provides implementation teams with a holistic approach, guidance, and conduct of good practice towards implementing a computer-based knowledge management system, which increases chances of success.

The 21st century world never anticipated a scenario in which it would be thrown into disarray by a fast-spreading viral disease, during which governments hastily had to enforce curfews by imposing travel and social gathering restrictions in order to contain it. The coronavirus disease of 2019 disrupted global supply chains and economies and caused death in every part of the world. Health departments and hospitals became the centres of attention as healthcare workers battled to save the lives of the infected. Governments struggled to calm citizens as the spread of incorrect and, sometimes, malicious information dominated all social media channels. The absence of established knowledge-sharing strategies and channels, knowledge about the disease or how to deal with the pandemic exacerbated the situation. This study investigates knowledge management systems as a sustainability strategy during a pandemic from three perspectives: understanding the disease, sourcing the required drugs and communicating with the citizens during a pandemic. The researchers adopted a survey research strategy for the study. The study makes an essential contribution to the value of KMS and the need to adopt them in the healthcare sector, particularly when faced with pandemics such as COVID-19.
