Sharing information across patient subgroups to draw conclusions from sparse treatment networks

Network meta-analysis (NMA) usually provides estimates of the relative effects with the highest possible precision. However, sparse networks with few available studies and limited direct evidence can arise, threatening the robustness and reliability of NMA estimates. In these cases, the limited amount of available information can hamper the formal evaluation of the underlying NMA assumptions of transitivity and consistency. In addition, NMA estimates from sparse networks are expected to be imprecise and possibly biased as they rely on large-sample approximations that are invalid in the absence of sufficient data. We propose a Bayesian framework that allows sharing of information between two networks that pertain to different population subgroups. Specifically, we use the results from a subgroup with a lot of direct evidence (a dense network) to construct informative priors for the relative effects in the target subgroup (a sparse network). This is a two-stage approach where at the first stage, we extrapolate the results of the dense network to those expected from the sparse network. This takes place by using a modified hierarchical NMA model where we add a location parameter that shifts the distribution of the relative effects to make them applicable to the target population. At the second stage, these extrapolated results are used as prior information for the sparse network. We illustrate our approach through a motivating example of psychiatric patients. Our approach results in more precise and robust estimates of the relative effects and can adequately inform clinical practice in presence of sparse networks.

Prevalence and Perception Among Saudi Arabian Population About Resharing of Information on Social Media Regarding Natural Remedies as Protective Measures Against COVID-19

INTRODUCTION

Ever since COVID-19 was declared as a global pandemic, there has been a prevalence of misinformation circulating online on social media platforms. In order to better tackle COVID-19 it is important to determine how the general population perceive the sharing of medical information on social media platforms. Based on this, the aim of the study is to analyse the perception of Saudi Arabian Health Care Workers' (HCWs) and Non-Health Care Workers' (NHCWs) regarding the sharing and resharing of medical information, whether true or false, on social media platforms regarding COVID-19.

METHODS

To achieve the aim of this study, the general objective is to identify the most commonly used Social Media Platforms, determine the proportion of the Saudi Arabian population who have participated in recirculating information in those social media platforms, and to analyse their perception of medical information sharing in social media platforms. This study was conducted using a quantitative research methodology. The measurement tool used for this study was an online survey conducted using Google Survey. A 10-item questionnaire was adopted and translated to Arabic to conduct the survey.

RESULTS

The total number of responses for the study were N=1249. The findings of the study indicate that Saudi Arabian general population understand the prevalence of unverified information, but are accepting of the practice of sharing information without evidence on social media platforms, with the belief that such information does not cause actual harm to the general public, but instead would be beneficial. WhatsApp was the most preferred social media platform for receiving and sharing information among participants, followed by Twitter and Snapchat.

CONCLUSION

The findings of this study indicate that the Saudi Arabian population are more wary than the global general population regarding misinformation online on social media platforms regarding COVID-19.

Leading Employees Through the Crises: Key Competences of Crises Management in Healthcare Facilities in Coronavirus Pandemic

Purpose

The fast and shocking onset of the crisis caused by the COVID-19 virus created the need for a complete crisis management of healthcare facilities to manage the current stage of the crisis. The purpose of our research is to examine the relations between the competences of crisis management in healthcare facilities and the performance of employees, measured during the acute stage of the crisis by their feeling of satisfaction, safety and creation of conditions for work, whereby we assume that these variables are mutually interlinked by the sharing of information, teamwork and cognitive diversity of the work teams.

Materials and Methods

A questionnaire survey was created and used based on a sample of 216 mid-level managers of health care facilities in Slovakia, which took place during the first month after the outbreak of the crisis (during the month of March/April 2020). The Baron and Kenny mediator model has been used for research purposes and the Freedman–Schatzkin test has been used to test the mediator effect. Regression analysis has been used to verify the hypotheses. The control variables were the size of the healthcare facility based on the number of employees, gender and age of the manager, his position in the management hierarchy and the duration of practice in a management position. The ANOVA analysis of variance was used to analyze multiple dependencies. The level of significance was 5%. The research sample consisted of 216 managers at different types of healthcare facilities.

Results

The hypothesis for the dependency between the crisis competences of management and performance of teams during the acute stage of the crisis, facilitated by sharing information, teamwork and cognitive diversity of crisis management was confirmed. It is a multilateral incomplete mediation, where almost two thirds of the total effect are facilitated by mediators, of which the sharing of information has the greatest effect (35%).

Conclusion

Based on our mediation model, healthcare facilities, which strive to implement crisis management during the acute stage of the crisis, should place emphasis especially on reliable background information and the fast sharing of information, supporting the performance of healthcare teams. The strategies for achieving these goals should also include education focused on the development of managerial competences.

To zoom or not to zoom - the training of communicative competencies in times of Covid 19 at Witten/Herdecke University illustrated by the example of "sharing information"

Since October 2018, a longitudinal communication curriculum for medical students has been implemented at Witten/Herdecke University. In the summer semester 2020, the concept for the 4th preclinical semester included a practical training on "sharing information", which consisted of three two-hour face-to-face sessions with simulated patients (SP). Due to the Covid 19 pandemic, teaching was changed to an inverted classroom concept combining asynchronous and synchronous teaching. The students worked at the beginning of the semester on an e-learning module of the learning platform docCom.deutsch on the topic "sharing information" using reflection and processing tasks. In two digital sessions, the students then were able to practice discharge interviews and discussions about risk communication illustrated by the example of screening methods for cancer prevention. In the first zoom session, students practiced in role-plays among themselves. In the second zoom session, they practiced with SP. The evaluation results revealed that 76% of the responding students considered working with the e-learning module as a good preparation for the interviews. According to the evaluation results, satisfaction with the Zoom meeting including SP contact was slightly higher than those with role-plays among themselves. Although the group atmosphere was rated by all responding students as conducive to learning, almost half of them confirmed that using Zoom significantly impaired the atmosphere (47%). In retrospect, the conversion of the communication training to a digital format worked better than expected from both the perspective of teachers and students. The students explicitly appreciated working with SP. From the teachers' perspective, some specific aspects of successful communication were difficult to reflect on, e.g. non-verbal communication. The use of e-learning as a preparation for practical exercises has proven successful and will be continued in the future.

Respecting patient confidentiality

Nurses face a particular challenge in respecting the confidentiality of patients in a world where information is quickly shared and where information about illness can be sensitive. We have a duty of care towards patients. That duty includes maintaining privacy (protecting them from undue intrusion), and confidentiality (by the discreet management of information about themselves that they share with us). Legislation on confidentiality comes from different sources and should be interpreted in the clinical setting. This article summarises the principal requirements set out in the legislation and directs readers to questions and tools designed to help them explore the extent to which patient confidentiality is respected where they work.
