Evaluation of an Enhanced Role-Based Access Control model to manage information access in collaborative processes for a statewide clinical education program.

BACKGROUND: Managing information access in collaborative processes is a critical requirement to team-based biomedical research, clinical education, and patient care. We have previously developed a computation model, Enhanced Role-Based Access Control (EnhancedRBAC), and applied it to coordinate information access in the combined context of team collaboration and workflow for the New York State HIV Clinical Education Initiative (CEI) program. We report in this paper an evaluation study to assess the effectiveness of the EnhancedRBAC model for information access management in collaborative processes when applied to CEI. METHODS: We designed a cross-sectional study and performed two sets of measurement: (1) degree of agreement between EnhancedRBAC and a control system CEIAdmin based on 9152 study cases, and (2) effectiveness of EnhancedRBAC in terms of sensitivity, specificity, and accuracy based on a gold-standard with 512 sample cases developed by a human expert panel. We applied stratified random sampling, partial factorial design, and blocked randomization to ensure a representative case sample and a high-quality gold-standard. RESULTS: With the kappa statistics of four comparisons in the range of 0.80-0.89, EnhancedRBAC has demonstrated a high level of agreement with CEIAdmin. When evaluated against the gold-standard, EnhancedRBAC has achieved sensitivities in the range of 97-100%, specificities at the level of 100%, and accuracies in the range of 98-100%. CONCLUSIONS: The initial results have shown that the EnhancedRBAC model can be effectively used to manage information access in the combined context of team collaboration and workflow for coordination of clinical education programs. Future research is required to perform longitudinal evaluation studies and to assess the effectiveness of EnhancedRBAC in other applications.

An enhancement of the role-based access control model to facilitate information access management in context of team collaboration and workflow.

Although information access control models have been developed and applied to various applications, few of the previous works have addressed the issue of managing information access in the combined context of team collaboration and workflow. To facilitate this requirement, we have enhanced the Role-Based Access Control (RBAC) model through formulating universal constraints, defining bridging entities and contributing attributes, extending access permissions to include workflow contexts, synthesizing a role-based access delegation model to target on specific objects, and developing domain ontologies as instantiations of the general model to particular applications. We have successfully applied this model to the New York State HIV Clinical Education Initiative (CEI) project to address the specific needs of information management in collaborative processes. An initial evaluation has shown this model achieved a high level of agreement with an existing system when applied to 4576 cases (kappa=0.801). Comparing to a reference standard, the sensitivity and specificity of the enhanced RBAC model were at the level of 97-100%. These results indicate that the enhanced RBAC model can be effectively used for information access management in context of team collaboration and workflow to coordinate clinical education programs. Future research is required to incrementally develop additional types of universal constraints, to further investigate how the workflow context and access delegation can be enriched to support the various needs on information access management in collaborative processes, and to examine the generalizability of the enhanced RBAC model for other applications in clinical education, biomedical research, and patient care.

Science, healthcare system, and government effectiveness perception and COVID-19 vaccination acceptance and hesitancy in a global sample: an analytical cross-sectional analysis.

BACKGROUND: Determinants of COVID-19 vaccine acceptance are complex; how perceptions of the effectiveness of science, healthcare and government impact personal COVID-19 vaccine acceptance is unclear, despite all three domains providing critical roles in development, funding and provision, and distribution of COVID-19 vaccine. OBJECTIVE: To estimate impact of perception of science, healthcare systems, and government along with sociodemographic, psychosocial, and cultural characteristics on vaccine acceptance. DESIGN: We conducted a global nested analytical cross-sectional study of how the perceptions of healthcare, government and science systems have impacted COVID-19 on vaccine acceptance. SETTING: Global Facebook, Instagram and Amazon Mechanical Turk (mTurk) users from 173 countries. PARTICIPANTS: 7411 people aged 18 years or over, and able to read English, Spanish, Italian, or French. MEASUREMENTS: We used Χ2 analysis and logistic regression-derived adjusted Odds Ratios (aORs) and 95% CIs to evaluate the relationship between effectiveness perceptions and vaccine acceptance controlling for other factors. We used natural language processing and thematic analysis to analyse the role of vaccine-related narratives in open-ended explanations of effectiveness. RESULTS: After controlling for confounding, attitude toward science was a strong predictor of vaccine acceptance, more so than other attitudes, demographic, psychosocial or COVID-19-related variables (aOR: 2.1; 95% CI: 1.8 to 2.5). The rationale for science effectiveness was dominated by vaccine narratives, which were uncommon in other domains. LIMITATIONS: This study did not include participants from countries where Facebook and Amazon mTurk are not available, and vaccine acceptance reflected intention rather than actual behaviour. CONCLUSIONS: As our findings show, vaccine-related issues dominate public perception of science's impact around COVID-19, and this perception of science relates strongly to the decision to obtain vaccination once available.

Risk of COVID-19-related bullying, harassment and stigma among healthcare workers: an analytical cross-sectional global study.

OBJECTIVES: Essential healthcare workers (HCW) uniquely serve as both COVID-19 healers and, potentially, as carriers of SARS-CoV-2. We assessed COVID-19-related stigma and bullying against HCW controlling for social, psychological, medical and community variables. DESIGN: We nested an analytical cross-sectional study of COVID-19-related stigma and bullying among HCW within a larger mixed-methods effort assessing COVID-19-related lived experience and impact. Adjusted OR (aOR) and 95% CIs evaluated the association between working in healthcare settings and experience of COVID-19-related bullying and stigma, controlling for confounders. Thematic qualitative analysis provided insight into lived experience of COVID-19-related bullying. SETTING: We recruited potential participants in four languages (English, Spanish, French, Italian) through Amazon Mechanical Turk's online workforce and Facebook. PARTICIPANTS: Our sample included 7411 people from 173 countries who were aged 18 years or over. FINDINGS: HCW significantly experienced more COVID-19-related bullying after controlling for the confounding effects of job-related, personal, geographic and sociocultural variables (aOR: 1.5; 95% CI 1.2 to 2.0). HCW more frequently believed that people gossip about others with COVID-19 (OR: 2.2; 95% CI 1.9 to 2.6) and that people with COVID-19 lose respect in the community (OR: 2.3; 95% CI 2.0 to 2.7), both which elevate bullying risk (OR: 2.7; 95% CI 2.3 to 3.2, and OR: 3.5; 95% CI 2.9 to 4.2, respectively). The lived experience of COVID-19-related bullying relates frequently to public identities as HCW traverse through the community, intersecting with other domains (eg, police, racism, violence). INTERPRETATION: After controlling for a range of confounding factors, HCW are significantly more likely to experience COVID-19-related stigma and bullying, often in the intersectional context of racism, violence and police involvement in community settings.

Assessing Training Interests of Latin American and Caribbean Immigrant-serving HIV/AIDS, STD, and Hepatitis C Providers in New York State, United States.

Healthcare providers may be ill-equipped to address the specific care needs of refugee/immigrant (RI) patient populations. We assessed continuing education (CE) training interests among HIV/AIDS, STD, and Hepatitis C (HASH) providers in New York State (NYS), United States, who serve RI patients from Latin America and the Caribbean (LAC). An online survey was completed by 156 HASH providers during a three-month period in Spring 2018. HASH providers serving LAC patients indicate interest in additional training to address the unique needs of the RI community. We noted a strong interest for more tailored learning opportunities in issues that impact refugee health.

Access to digital and social media among Romanian HIV/AIDS clinical providers.

The WHO/UNAIDS suggests that digital tools - such as social media and online training opportunities, can connect providers in difficult social and medical contexts to providers elsewhere for guidance, support, and advice. Social media is emerging as an innovative option for connecting clinicians together and for enhancing access to professional resources. In Romania, characterized by an atypical HIV/AIDS epidemic which is further challenged by a range of access complexities, it is unclear how often - and which kinds of - social media clinicians use to support clinical care. This study was conducted to ascertain social media use for clinical providers based in two regions of Romania (Transylvania and Moldavia) who face distance challenges that could potentially be alleviated by social media interaction. We used an online survey to understand what social media are currently popular and perceived to be useful for learning clinical information. Descriptive and bivariate analyses were conducted. Providers indicated Facebook and WhatsApp were the most common social media platforms, with 62% and 45% reporting daily use, respectively. Providers who used one media platform were significantly more likely to use another social media platform (p < .05). These data are helpful for creating an online training platform on HIV/AIDS for Romanian clinical providers.
