AI Article Synopsis

  • Understanding behavioral and social drivers of vaccination is essential to combat vaccine hesitancy, particularly in Vietnam, where adult primary vaccination rates are high but booster and children's vaccination rates are low.
  • A scoping review analyzed research from various databases, uncovering 39 studies involving over 224,000 participants, which showed intentions to vaccinate among adults ranged from 58% to 98%, while parental intentions for children were between 32.8% and 79.6%.
  • Key factors influencing vaccination included perceived disease severity, benefits of the vaccine, healthcare worker recommendations, and societal perceptions, with information sources primarily being social media and television.

Article Abstract

Background: Understanding of the behavioural and social drivers (BeSD) of vaccination is key to addressing vaccine hesitancy and accessibility issues. Vietnam's national COVID-19 vaccination programme resulted in high uptake of primary doses among adults, but lower booster doses for adults and primary doses for 5-11 years. This scoping review assessed BeSD influencing COVID-19 vaccine uptake in Vietnam to design interventions on reaching the national vaccination targets.

Method: We conducted a scoping review by searching PubMed, MedRxiv, LitCOVID, COVID-19 LOVE platform, WHO's COVID-19 research database and seven dominant Vietnamese language medical journals published in English or Vietnamese between 28 December 2019 and 28 November 2022. Data were narratively synthesised and summarised according to the four components of the WHO BeSD framework. The drivers were then mapped along the timeline of COVID-19 vaccine deployment and the evolution of the pandemic in Vietnam.

Results: We identified 680 records, of which 39 met the inclusion criteria comprising 224 204 participants. Adults' intention to receive COVID-19 vaccines for themselves (23 studies) ranged from 58.0% to 98.1%. Parental intention to vaccinate their under 11-year-old children (six studies) ranged from 32.8% to 79.6%. Key drivers of vaccination uptake were perceived susceptibility and severity of disease, perceived vaccine benefits and safety, healthcare worker recommendation, and positive societal perception. Commonly reported COVID-19 vaccines' information sources (six studies) were social and mainstream media (82%-67%), television (72.7%-51.6%) and healthcare workers (47.5%-17.5%). Key drivers of COVID-19 uptake remained consistent for both adults and children despite changes in community transmission and vaccine deployment.

Conclusion: Key enablers of vaccine uptake for adults and children included perceived disease severity, perceived vaccine benefits and safety and healthcare worker recommendations. Future studies should assess vaccine communication targeted to these drivers, national policies and political determinants to optimise vaccine uptake.

With breakthroughs in Natural Language Processing and Artificial Intelligence (AI), the usage of Large Language Models (LLMs) in academic research has increased tremendously. Models such as Generative Pre-trained Transformer (GPT) are used by researchers in literature review, abstract screening, and manuscript drafting. However, these models also present the attendant challenge of providing ethically questionable scientific information.

Spontaneous epidural hematoma (EDH) is a rare sickle cell disease (SCD) complication. We report 3 pediatric cases with SCD and spontaneous EDH and 1 with subgaleal hematomas in the setting of vaso-occlusive crises and elaborate on their presentation and management. Through a scoping review, we identified 71 additional cases reported from 1970 to 2024 and highlighted notable features.

Algorithmic individual fairness and healthcare: a scoping review.

JAMIA Open

February 2025

Intelligent Systems Program, University of Pittsburgh, Pittsburgh, PA 15213, United States.

Objectives: Statistical and artificial intelligence algorithms are increasingly being developed for use in healthcare. These algorithms may reflect biases that magnify disparities in clinical care, and there is a growing need for understanding how algorithmic biases can be mitigated in pursuit of algorithmic fairness. We conducted a scoping review on algorithmic individual fairness (IF) to understand the current state of research in the metrics and methods developed to achieve IF and their applications in healthcare.

Background: As the global population ages, there is increasing pressure on health systems to provide high-quality and cost-effective care for this growing segment of the population. Reablement, primarily a strategic home-based rehabilitation approach, has been demonstrated to be a cost-effective, multidisciplinary, holistic, and person-centred approach to maintaining functional independence as one ages. Given that care delivery in the home setting for older persons is complex, a key feature of effective implementation of reablement is the integration of a multidisciplinary team.

Background: Demoralization is a complex construct comprising of several clinical phenomena that has gained increasing interest in clinical practice and research; however, the concept needs to be sufficiently specified and clearly described. A concept analysis of demoralization is necessary to integrate previous research findings and establish the scientific foundation for future intervention research.

Aim: To analyze the concept of demoralization in terms of its antecedents, attributes, consequences, and empirical referents in health.
