ABSTRACT

Background: The Kingdom of Saudi Arabia (KSA) was the fourth country in the world to authorize the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine, which it rolled out on December 17, 2020 and first targeted at healthcare workers (HCWs). This study assesses vaccine uptake among this group during the first month of its availability. Methods: A national cross-sectional, pilot-validated, self-administered survey was conducted among HCWs in the KSA between December 27, 2020 and January 3, 2021. The survey included sociodemographic details, previous contact with COVID-19 patients, previous infection with COVID-19, receiving (or registering with the Ministry of Health website to receive) the COVID-19 vaccine, sources of HCWs information on vaccines, awareness of emerging variants of concern, and anxiety level using the 7 item Generalized Anxiety Disorder assessment. A descriptive bivariate analysis and multivariate logistic binary regression analysis were performed. The primary evaluated outcome was vaccine uptake. Results: Of the 1,058 participants who completed the survey, 704 (66.5%) were female, and 626 (59.2%) were nurses. Of all the respondents, 352 (33.27%) were enrolled to receive or had already received the vaccine, while 706 (66.73%) had not registered. In a bivariate analysis, not enrolling for vaccination was more likely in females than males (78.5% vs. 21.5%, P < 0.001), HCWs between the ages of 20 and 40 years than those > 40 years (70.4% vs. 29.6%, P = 0.005), Saudi HCWs than expatriates (78% vs 22%, P < 0.001), and among HCWs who used social media as a source of information than those who did not (69.8% vs. 38.6%, P < 0.001) . In a multivariate analysis, independent factors for not enrolling to receive the vaccine included being female (aOR = 0.287, 95%CI = 0.206, 0.401, P < 0.001), being less than 40 years of age (aOR = 1.021, 95%CI = 1.002,1.040, P = 0.032), and using social media as a source of information (aOR = 0.207, 95%CI = 0.132,1.354, P = 0.001 ). Factors associated with uptake were being a Saudi national (aOR = 1.918, 95%CI = 1.363,2.698, P < 0.001), working in an intensive care unit (aOR = 1.495, 95%CI = 1.083,2.063, P = 0.014), and working at a university hospital (aOR = 1.867, 95%CI = 1.380,2.525, P < 0.001). Conclusions: A low level of vaccine uptake was observed especially in female HCWs, those younger than 40 years old, and those who used social media as their source of vaccine information. This survey provides important information for public health authorities in order to scale up vaccination campaigns targeting these HCWs to increase vaccine enrollment and uptake.

ABSTRACT

The evolutionary process of genetic recombination has the potential to rapidly change the properties of a viral pathogen, and its presence is a crucial factor to consider in the development of treatments and vaccines. It can also significantly affect the results of phylogenetic analyses and the inference of evolutionary rates. The detection of recombination from samples of sequencing data is a very challenging problem, and is further complicated for SARS-CoV-2 by its relatively slow accumulation of genetic diversity. The extent to which recombination is ongoing for SARS-CoV-2 is not yet resolved. To address this, we use a parsimony-based method to reconstruct possible genealogical histories for samples of SARS-CoV-2 sequences, which enables the analysis of recombination events that could have generated the data. We propose a framework for disentangling the effects of recurrent mutation from recombination in the history of a sample, and hence provide a way of estimating the probability that ongoing recombination is present. We apply this to samples of sequencing data collected in England and in South Africa, and find compelling evidence of ongoing recombination.

ABSTRACT

Introduction Coronavirus disease 2019 (COVID-19) has caused an unprecedented health crisis around the world, not least because of its heterogeneous clinical presentation and course. The new information on the pandemic emerging daily has made it challenging for healthcare workers (HCWs) to stay current with the latest knowledge, which could influence their attitudes and practices during patient care. Methods This study is a follow-up evaluation of changes in HCWs’ knowledge, attitudes, and practices as well as anxiety levels regarding COVID-19 since the beginning of the pandemic. Data were collected through an anonymous, predesigned, self-administered questionnaire that was sent online to HCWs in Saudi Arabia. Results The questionnaire was sent to 1500 HCWs, with a 63.8% response rate (N=957). The majority of respondents were female (83%), and the most common age group was 31–40 years (52.2%). Nurses constituted 86.3% of the respondents. HCWs reported higher anxiety during the COVID-19 pandemic which increased from 4.91±2.84 to 8.6±2.27 on an 11-point Likert scale compared to other viral outbreaks. HCWs believed that their own preparedness as well as that of their hospital’s intensive care unit (ICU) or emergency room (ER) was higher during the COVID-19 pandemic than during the Middle East respiratory syndrome coronavirus pandemic (2012–2015). About 58% of HCWs attended one or more simulations concerning the management of COVID-19 patients in their ICU/ER, and nearly all had undergone N95 mask fit testing. The mean score of HCWs’ knowledge of COVID-19 was 9.89/12. For most respondents (94.6%), the perception of being at increased risk of infection was the main cause of anxiety related to COVID-19; the mean score of anxiety over COVID-19 increased from 4.91±2.84 before to 8.6±2.27 during the pandemic in Saudi Arabia. Conclusions HCWs’ anxiety levels regarding COVID-19 have increased since a pandemic was declared. It is vital that healthcare facilities provide more emotional and psychological support for all HCWs.

ABSTRACT

BackgroundHealthcare workers (HCWs) travel-related anxiety needs to be assessed in light of the emergence of SARS-CoV-2 mutations. MethodsAn online, cross-sectional questionnaire among HCWs between December 21, 2020 to January 7, 2021. The outcome variables were HCWs knowledge and awareness of the SARS-CoV-2 B.1.1.7 lineage, and its associated travel worry and Generalized Anxiety Disorder (GAD-7) score. ResultsA total of 1,058 HCWs completed the survey; 66.5% were female, 59.0% were nurses. 9.0% indicated they had been previously diagnosed with COVID-19. Regarding the B.1.1.7 lineage, almost all (97.3%) were aware of its emergence, 73.8% were aware that it is more infectious, 78.0% thought it causes more severe disease, and only 50.0% knew that current COVID-19 vaccines are effective in preventing it. Despite this, 66.7% of HCWs were not registered to receive the vaccine. HCWs most common source of information about the new variant was social media platforms (67%), and this subgroup was significantly more worried about traveling. Nurses were more worried than physicians (P=0.001). ConclusionsMost HCWs were aware of the emergence of SARS-CoV-2 B.1.1.7 variant and expressed substantial travel worries. Increased worry levels were found among HCWs who used social media as their main source of information, those with lower levels of COVID-19 vaccine uptake, and those with higher GAD-7 scores. The utilization of official social media platforms could improve accurate information dissemination among HCWs regarding the pandemics evolving mutations. Targeted vaccine campaigns are warranted to assure HCWs about the efficacy of COVID-19 vaccines toward SARS-CoV-2 variants.

ABSTRACT

Objectives The aim of this study was to compare the perception, confidence, hesitancy, and acceptance rate of various COVID-19 vaccine types among healthcare workers (HCWs) in Saudi Arabia, a nation with MERS-CoV experience. Design National cross-sectional, pilot-validated questionnaire. Setting Online, self-administered questionnaire among HCWs. Participants A total of 2,007 HCWs working in the Kingdom of Saudi Arabia participated; 75.3% completed the survey and were included in the analysis. Intervention Data were collected through an online survey sent to HCWs during November 1-15, 2020. The main outcome measure was HCW acceptance of COVID-19 candidate vaccines. The associated factors of vaccination acceptance were identified through logistic regression analysis and via measurement of the level of anxiety, using the generalized anxiety disorder 7 (GAD7) scale. Results Among the 1512 HCWs who were included, 62.4% were women, 70.3% were between 21 and 40 years of age, and the majority (62.2%) were from tertiary hospitals. In addition, 59.5% reported knowing about at least one vaccine; 24.4% of the participants were sure about their willingness to receive the ChAdOx1 nCoV-19 vaccine, and 20.9% were willing to receive the RNA BNT162b2 vaccine. However, 18.3% reported that they would refuse to receive the Ad5-vectored vaccine, and 17.9% would refuse the Gam-COVID-Vac vaccine. Factors that influenced the differential readiness of HCWs included their perceptions of the vaccine's efficiency in preventing the infection (33%), their personal preferences (29%), and the vaccine's manufacturing country (28.6%). Conclusions Awareness by HCWs of the several COVID-19 candidate vaccines could improve their perceptions and acceptance of vaccination. Reliable sources on vaccine efficiency could improve vaccine uptake, so healthcare authorities should use reliable information to decrease vaccine hesitancy among frontline healthcare providers.

ABSTRACT

ObjectivesThis study aimed to identify COVID-19 vaccine perception, acceptance, confidence, hesitancy, and barriers among healthcare workers (HCW). MethodsAn online national cross-sectional pilot-validated questionnaire was self-administered by HCW in Saudi Arabia, a nation with MERS-CoV experience. The main outcome variable was HCWs acceptance of COVID-19 vaccine candidates. The associated factors of vaccination acceptance were identified through a logistic regression analysis and the level of anxiety using generalized anxiety disorder 7. ResultOut of 1512 HCWs who completed the study questionnaire--944 (62.4%) women and 568 (37.6%) men--1058 (70%) were willing to receive COVID-19 vaccines. Logistic regression analysis revealed that male HCWs (ORa=1.551, 95% CI: 1.122-2.144), HCWs who believe in vaccine safety (ORa=2.151; 95% CI:1.708-2.708), HCWs who believe that COVID vaccines are the most likely way to stop the pandemic (ORa=1.539; 95% CI: 1.259-1.881), and HCWs who rely on Centers for Disease Control and Prevention website for COVID 19 updates (ORa=1.505, 95% CI: 1.125-2.013) were significantly associated with reporting willingness to be vaccinated. However, HCWs who believed vaccines were rushed without evidence-informed testing were found to be 60% less inclined to accept COVID-19 vaccines (ORa=0.394, 95% CI: 0.298- 0.522). ConclusionMost HCWs are willing to receive COVID-19 vaccines once available; yet, satisfactoriness of COVID-19 vaccination among HCWs is crucial because health professionals knowledge and confidence toward vaccines are important determining factors for their own vaccine acceptance and recommendation to their patients.

ABSTRACT

Background: Many healthcare systems initiated rapid training with COVID-19 simulations for their healthcare workers (HCWs) to build surge capacity and optimize infection control measures. This study aimed to describe COVID-19 simulation drills in international healthcare centers. Methods: This is a cross-sectional survey among simulation team leaders and HCWs, based on each center's debriefing reports from simulation centers from 30 countries in all WHO regions where COVID-19 simulation drills were conducted. The primary outcome measures were the COVID-19 simulations' characteristics, outcomes, facilitators, obstacles, and challenges encountered during the simulation sessions. Results: Invitation was sent to 500 simulation team leaders and HCWs, and 343 responded. Those who completed the study comprised 121 participants: 62.8% females; 56.2% physicians; 41.3% from East Mediterranean (EMRO) countries; 25.6% from Southeast Asian countries (SERO); and 12.4% from Europe. The frequency of simulation sessions was monthly (27.1%), weekly (24.8%), twice weekly (19.8%), or daily (21.5%). Among participants, 55.6% reported the team's full engagement in the simulation sessions. The average session length was 30–60 minutes. The most commonly reported debriefing leaders were ICU staff, simulation lab staff, and E.R. facilitators, and the least common were infection control staff. A total of 80% reported "a lot" to "a great improvement" in terms of clinical preparedness after simulation sessions, and 70% were satisfied with the COVID-19 simulation sessions and thought they were better than expected. Most of the perceived issues reported were related to infection control measures, followed by team dynamics, logistics, and patient transport issues. Conclusion: Simulation centers team leaders and HCWs reported positive feedback on COVID-19 simulation sessions. The presence of multiprofessional personnel during drills is warranted. These drills are a valuable tool for rehearsing safe dynamics of HCWs on the frontline of COVID-19.Trial registration: Not applicable.
