User Experiences of the NZ COVID Tracer App in New Zealand: Thematic Analysis of Interviews.

BACKGROUND: For mobile app-based COVID-19 contact tracing to be fully effective, a large majority of the population needs to be using the app on an ongoing basis. However, there is a paucity of studies of users, as opposed to potential adopters, of mobile contact tracing apps and of their experiences. New Zealand, a high-income country with western political culture, was successful in managing the COVID-19 pandemic, and its experience is valuable for informing policy responses in similar contexts. OBJECTIVE: This study asks the following research questions: (1) How do users experience the app in their everyday contexts? and (2) What drives the use of the app? METHODS: Residents of New Zealand's Auckland region, which encompasses the country's largest city, were approached via Facebook, and 34 NZ COVID Tracer app users were interviewed. Interview transcripts were analyzed using thematic analysis. RESULTS: Interviews ranged in duration from 15 to 50 minutes. Participants ranged in age from those in their late teens to those in their early sixties. Even though about half of the participants identified as White New Zealanders of European origin, different ethnicities were represented, including New Zealanders of South Pacific, Indian, Middle Eastern, South American, and Southeast Asian descent. Out of 34 participants, 2 (6%) identified as Maori (Indigenous New Zealanders). A broad range of careers were represented, from top-middle management to health support work and charity work. Likewise, educational backgrounds ranged broadly, from high school completion to master's degrees. Out of 34 participants, 2 (6%) were unemployed, having recently lost their jobs because of the pandemic. The thematic analysis resulted in five major themes: perceived benefits, patterns of use, privacy, social influence, and need for collective action. Benefits of using the app to society in general were more salient to the participants than immediate health benefits to the individual. Use, however, depended on the alert level and tended to decline for many participants at low alert levels. Privacy considerations played a small role in shaping adoption and use, even though the participants were highly aware of privacy discourse around the app. Participants were aware of the need for high levels of adoption and use of the app to control the pandemic. Attempts to encourage others to use the app were common, although not always successful. CONCLUSIONS: Appeals to civic responsibility are likely to drive the use of a mobile contact tracing app under the conditions of high threat. Under the likely scenario of COVID-19 remaining endemic and requiring ongoing vigilance over the long term, other mechanisms promoting the use of mobile contact tracing apps may be needed, such as offering incentives. As privacy is not an important concern for many users, flexible privacy settings in mobile contact tracing apps allowing users to set their optimal levels of privacy may be appropriate.

Knowledge management systems success in healthcare: Leadership matters.

PURPOSE: To deliver high-quality healthcare doctors need to access, interpret, and share appropriate and localised medical knowledge. Information technology is widely used to facilitate the management of this knowledge in healthcare organisations. The purpose of this study is to develop a knowledge management systems success model for healthcare organisations. METHOD: A model was formulated by extending an existing generic knowledge management systems success model by including organisational and system factors relevant to healthcare. It was tested by using data obtained from 263 doctors working within two district health boards in New Zealand. RESULTS: Of the system factors, knowledge content quality was found to be particularly important for knowledge management systems success. Of the organisational factors, leadership was the most important, and more important than incentives. CONCLUSION: Leadership promoted knowledge management systems success primarily by positively affecting knowledge content quality. Leadership also promoted knowledge management use for retrieval, which should lead to the use of that better quality knowledge by the doctors, ultimately resulting in better outcomes for patients.

Nonequilibrium phase transition of contact processes with the Kauffman NK model.

We consider a multistate contact process (CP) in which new particles are created with probabilities that depend on the fitness of the parent particle and with mutations that occur at the time of creation. The fitness is determined by the Kauffman NK model. Using Monte Carlo simulations, we show that such an evolutional CP exhibits critical behaviors that differ from the basic CP. In addition, we present numerical results suggesting that the fitness averaged over surviving particles exhibits a maximum value at the critical point.

The use of information technologies for knowledge sharing by secondary healthcare organisations in New Zealand.

PURPOSE: To explore the extent of use of information technologies (ITs) for knowledge sharing by secondary healthcare organisations in New Zealand. METHODS: We used a self-administered questionnaire to survey Chief Information Officers at all 21 of New Zealand's District Health Boards regarding the extent to which their organisations use knowledge sharing activities involving ITs. The list of activities to include in the questionnaire was compiled by reviewing the literature. We analysed the extent of use of the knowledge sharing activities using descriptive statistics, repeated measures ANOVA, and correlation analysis. RESULTS: The response rate was 76%. Although all the responding organisations reported using ITs to share knowledge, they used ITs to share documents significantly more than to support discussions or to connect employees to experts. Discussions via teleconferencing, videoconferencing, and email lists were significantly more common than discussions via social media technologies: electronic discussion forums, blogs, and on-line chatrooms. There were significant positive correlations between publishing and accessing documents, between using teleconferencing and using videoconferencing, and between publishing and finding contact details of experts. CONCLUSION: New Zealand's District Health Boards are using a range of ITs to share knowledge. Knowledge sharing activities emphasising the sharing of explicit knowledge (via exchanging documents in electronic form) are significantly more common than knowledge sharing activities emphasising the sharing of tacit knowledge (via technology-mediated discussions and via using technology to connect employees to experts). In view of the evidence in the literature that information technology may be highly effective in supporting tacit knowledge exchanges, our results suggest that health organisations should consider greater adoption of ITs for sharing tacit knowledge. The finding that several organisations are currently making extensive use of teleconferencing and videoconferencing facilities and expertise databases suggests that these technologies are useful and could be of benefit to other healthcare providers and that barriers to their adoption can be overcome. In order to facilitate the wider adoption of technologies, early adopters of both relatively established technologies and of the emerging technologies such as social media should be encouraged to publish accounts of their experiences of success and lessons learnt from any failures so that the knowledge gained is disseminated to the wider medical informatics community.
