ABSTRACT
INTRODUCTION: Due to increased exposure risk and the potential impact of COVID-19 infection, health care professionals (HCP) are a target group for COVID-19 vaccination. This study aimed to examine the acceptability of COVID-19 vaccines among HCP at the Queen Elizabeth Hospital, Barbados. DESIGN AND METHODS: A cross-sectional survey of HCP was conducted between February 14 and 27, 2021 using an online questionnaire. The questionnaire included demographic information, knowledge of novel coronavirus, intention to accept the COVID-19 vaccination, vaccine literacy (VL), and perceptions and attitudes regarding COVID-19 vaccines. Mean VL scores were calculated. The relationship between socio-demographic variables and vaccine intent was assessed using a multivariable logistic regression model. RESULTS: Of 343 HCPs, 55.1% indicated they would accept the COVID-19 vaccine if it were available; 44.9% expressed hesitancy towards the COVID-19 vaccine. We assessed the impact of socio-demographic factors and previous vaccine behavior on vaccine intent; after adjustment of the multivariable logistic regression model, non-Barbadian nationality and previous flu vaccine uptake were statistically significant predictors of reported intent to take the COVID-19 vaccine. Persons who indicated that they would take the vaccine had a higher mean vaccine literacy score [3.46 95% CI (3.40, 3.52)] than those who were not ready to take the vaccine immediately [3.23 95% CI (3.15, 3.30)]. VL scores were higher among the 29.5% of HCPs who believed vaccines should be mandatory. CONCLUSION: This study highlighted vaccine hesitancy among HCPs in the sole public tertiary hospital of Barbados. As HCP perceptions may help or hinder the campaign to promote vaccine uptake in Barbados, vaccine promotion programs targeting HCPs are needed to ensure the success of the country's COVID-19 vaccination drive.
ABSTRACT
BACKGROUND: Technology-enhanced learning includes the adaptive e-learning platform, a data-driven method with computer algorithms, providing customised learning enhancing critical thinking of individual learners. "Firecracker" - an online adaptive e-learning platform, and assessment software, promotes critical thinking, helps prepare students for courses and high-stakes examinations, and evaluates progress relative to co-learners. The objectives of this study were to determine the usage rates of Firecracker, examine the performance of Firecracker formative quizzes, identify the correlation between Firecracker use and performance with that of performance at summative course assessments, and assess students' satisfaction with Firecracker usage. METHODS: Study participants were Year-2 MBBS (Bachelor of Medicine, Bachelor of Surgery) students (n=91) of the Faculty of Medical Sciences, The University of the West Indies, Cave Hill Campus, Barbados. The Firecracker Administrator uploaded quizzes covering basic science content in the Cardiovascular System course. Access, usage, and performance on Firecracker formative quizzes were retrieved from the Firecracker dashboard. A questionnaire sought the views of study participants. RESULTS: Seven sets of quizzes were administered over nine weeks, with weekly student completion rates ranging from 53% to 73%. Mean quiz scores ranged from 52% to 72%. Students completing >4 quiz sessions compared to those completing ≤4 demonstrated significantly better performance in Firecracker quizzes (P<0.01), final examinations (P<0.01) and in-course assessment plus final examination (P<0.05) scores. Correlations between overall Firecracker performance and in-course assessment marks (P<0.05); between total overall Firecracker performance and final examination (P<0.01); and overall Firecracker performance and total course marks (P<0.01) were all significant. Most students (70%) were happy using Firecracker and felt it complemented coursework (78%) and prepared them for course exams (58%) (P<0.01). CONCLUSION: Overall, Firecracker was perceived very positively and welcomed by the students. Students were satisfied with the Firecracker as a formative assessment tool, and its use correlated with improved performance in the course examinations.
