Healthcare workers' worries and Monkeypox vaccine advocacy during the first month of the WHO Monkeypox alert: Cross-sectional survey in Saudi Arabia (preprint)

Background: Monkeypox virus re-surged in May 2022 as a new potential global health threat with outbreaks bursting in multiple countries across different continents. This study was conducted during the first month of the WHO announcement to assess the healthcare workers (HCWs) within Saudi Arabia, exploring their perception, worries, and vaccine acceptance for Monkeypox in-line with the resolving COVID-19 pandemic. Methods: A national cross-sectional survey was conducted between May 27 and June 10, 2022, in Saudi Arabia. Data were collected on the sociodemographic and job-related characteristics, COVID-19 infection status, HCWs' worry levels of Monkeypox compared to COVID-19 and its sources, their perceptions, awareness, and HCWs' Monkeypox vaccination advocacy. Results: Among the 1130 HCWs who completed survey, 41.6% already developed COVID-19. Still, 56.5% were more worried from COVID-19 compared to Monkeypox, while the rest were more worried of Monkeypox disease. The main reason for their worry among 68.8% of the participants was development of another worldwide pandemic post COVID-19, followed by their worry of acquiring the infection themselves or their families (49.6%). Most HCWs (60%) rated their self-awareness of Monkeypox disease as moderate to high. Males and those who previously developed COVID-19 were significantly less likely to worry about Monkeypox. The worry about Monkeypox developing into a pandemic and the perception of Monkeypox being a severe disease correlated significantly positively with the odds of high worry from the disease. Regarding participants' advocacy for HCWs' vaccination against Monkeypox disease, those who developed COVID-19 previously and those who supported application of tighter infection control measures compared to the current ones to combat the disease were significantly predicted to agree for vaccination. 74.2% of the surveyed HCWs perceived that they need to read more about the Monkeypox disease after the survey. Conclusion: During the first month of the WHO's Monkeypox international alert, about half of HCWs in this study were more worried about Monkeypox disease as compared to COVID-19, and its possible progression into another pandemic. In addition, the majority were in favor of applying tighter infection prevention measures to combat the disease. The current study highlights areas needed for healthcare administrative about the HCWs' perceptions and readiness for Monkeypox especially in the event of any occurrence of local or international pandemic.

Monkeypox caused less worry than COVID-19 among the general population during the first month of the WHO Monkeypox alert (preprint)

BackgroundMonkeypox re-emerged in May 2022 as another global health threat. This study assessed the publics perception, worries, and vaccine acceptance for Monkeypox and COVID-19 during the first month of WHO announcement. MethodsA national cross-sectional survey was conducted between May 27 and June 5, 2022, in Saudi Arabia. Data were collected on sociodemographic characteristics, previous infection with COVID-19, worry levels regarding Monkeypox compared to COVID-19, awareness, and perceptions of Monkeypox, and vaccine acceptance. ResultsAmong the 1546 participants, most respondents (62%) were more worried about COVID-19 than Monkeypox. Respondents aged 45 years and above and those with a university degree or higher had lower odds of agreement with Monkeypox vaccination (OR .871, p-value .006, OR .719, p-value <0.001), respectively. Respondents with moderate to a high level of self and family commitment to infection control precautionary measures and those who expressed self and family worry of Monkeypox infection had significantly higher odds of vaccination agreement (OR 1.089 p-value=0.047, OR1.395 p-value=0.003) respectively. On the other hand, respondents who previously developed COVID-19 were significantly more worried about the Monkeypox disease (1.30 times more, p-value=0.020). ConclusionWorry levels amongst the public are higher from COVID-19 than Monkeypox. Perception of Monkeypox as a dangerous and virulent disease, worry from contracting the disease, and high commitment to infection precautionary measures were predictors of agreement with Monkeypox vaccination. While advanced age and high education level are predictors of low agreement with vaccination.

Epidemiological Assessment of Sars-Cov-2 Reinfection (preprint)

Introduction. Vaccination against SARS-CoV-2 infection has been shown to reduce the severity of infection; however, the overall reinfection rate in those unvaccinated, partially vaccinated and fully vaccinated remains unclear. Therefore, this study was undertaken to elucidate the rates and associated factors for such occurrences.Methods. This was a retrospective epidemiological report analysing 1362 COVID-19 reinfection cases in the Kingdom of Bahrain between April 2020 and July 2021. The differences in disease severity and characteristics of reinfection between various levels of vaccination statuses were determined among fully vaccinated, interrupted vaccination (positive test less than 14 days after receiving the second dose of vaccine), one dose of vaccination, post-reinfection vaccination and unvaccinated. Data were collected from the National COVID-19 Contact Tracing Team Database of individuals who tested positive for SARS-CoV-2.Results. During the study, reinfection cases increased from zero cases per month in April – June 2020 to a sharp peak of 579 reinfection cases in May 2021 followed by a rapid decline. Males constituted a significantly larger proportion of reinfections (n=821, 60.3%) than females (39.7%) (p<0.0001). Reinfection episodes were highest amongst the 30-39 years of age (n=405, 29.7%). The rate of reinfection increased with time from the initial infection with the lowest reinfection rate occurring at 3-6 months after the first infection (n=281, 20.6%) and the highest episodes occurring ≥9 months after initial infection (n=632, 46.4%). Comparison of the symptomatology between initial infection and reinfection episode for each individual showed that most individuals were asymptomatic during both episodes (n=486, 35.7%), while 265 (19.5%) individuals were symptomatic during both episodes. Reinfection disease severity was mild and differed across the cohort (X2 test p=0.003) with vaccinated patients less likely to have symptomatic reinfection (OR 0·71, p=0·004). Only 89 (6.6%) reinfection cases required hospitalization and there were no deaths (Poisson exact, 97.5% Cl 2.7 per 1000).Conclusion. Vaccine induced immunity and prior infection with or without vaccination were effective in reducing disease severity of reinfection episodes.

SARS-CoV-2 Omicron variant: healthcare workers' perceptions and beliefs of vaccine effectiveness and advocacy: a national survey during the first week of the World Health Organization variant alert (preprint)

Background: As COVID-19 Omicron variant spread in several countries, healthcare workers' (HCWs) perceptions of vaccine effectiveness, booster and worries warrant reassessment. Methods: Online questionnaire among HCWs in Saudi Arabia (KSA) was collected between Dec 1-6, 2021, aiming to assess their Omicron variant's perceptions, worries, and booster-vaccine advocacy. Results: Among the 1285 HCWs participants in the study, two-thirds were females, 41% were nurses,46.4% were physicians, and 50% worked in tertiary care hospitals. Vaccination was perceived to be the most effective way to prevent the spread of Omicron variant and future variants by 66.9%. The respondents perceived social distancing (78%), universal masking (77.8%), and avoiding unnecessary travel (71.4%), slightly superior to vaccination to prevent COVID-19 variants spread. Of the respondents, 99.5% received two doses of COVID-19 vaccine. Regarding the booster dose, 96% either received it or planned to receive it once they are eligible. 57.7% of the respondents agreed that Omicron could cause a new COVID-19 wave worldwide, 45.9% agreed it may cause another COVID-19 wave in Saudi Arabia and 46.1% indicated the possibility of another lockdown. Overall, the HCWs worry level of the Omicron variant correlated significantly and strongly with their perception of the effectiveness of vaccination and preventive measures. Male HCWs had a significant agreement with mandatory vaccination of all eligible adult populations while HCWs who are unwilling to receive the vaccine had a strong disagreement with mandatory vaccination. Conclusions: The current study was conducted in the first week of Omicron variant discovery in KSA and only two-thirds of HCWs felt that vaccination is the best option to prevent the variant spread, indicating the need to further motivation campaigns for vaccination and booster doses education among HCWs. HCWs had a strong belief in non-pharmacologic interventions that should be encouraged and augmented. It is important to further study and enhance coping strategies for HCWs as we move through the third year of the pandemic with more potential variants, to protect HCWs from fatigue and burnout.

Faculty Members’ Perspective on Virtual Interviews for Medical Residency Matching during the COVID-19 Crisis: A National Survey (preprint)

During the COVID-19 pandemic, conducting face-to-face medical residency interviews was challenging due to infection prevention precautions, social distancing and travel restrictions. Virtual interviews were implemented by the Saudi Commission for Health Specialties (SCFHS) as an alternative process for residency matching while striving to maintain the same quality standards. This national survey was conducted to assess the satisfaction and perceptions of faculty members’ virtual interviews performance in the assessment for the medical training residency programs. Among the participating 173 faculty members (34.1%) did not have previous experience with video-conferencing. Zoom application was the most commonly used platform (65.9%). Most (89.6%) of the faculty perceived virtual interviews as “adequate” for the candidates to express themselves, while almost half of the faculty (53.8%) agreed that virtual interviews allowed them to accurately reach an impression about the candidates. Overall, 73.4% of faculty felt comfortable ranking the virtually interviewed candidates. We conclude that the acceptance of participating faculty members in the first Saudi medical residency training matching cycle virtual interviewing event was well perceived. This study provides evidence for future application and research of virtual interviews in residency candidates' assessment, especially after the pandemic crisis resolves.

Predictors of Mortality Using Machine Learning Decision Tree Algorithm in Critically Ill Adult Patients with COVID-19 Admitted to the ICU. (preprint)

Background:The Coronavirus Disease-19 (COVID-19) caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a major cause of intensive care unit (ICU) admissions globally. Robust data of epidemiology, characteristics, and disease outcomes from different regions and populations showed considerable variations. However, limited number of reports addressed predictors of mortality utilizing machine learning methods. Herein, we aimed to describe the association and relationship of a predefined set of variables found to be predictive of 28–day ICU outcome among adults COVID-19 patients admitted to the ICU using a machine learning decision tree (DT) algorithm.Methods:This was a prospective/retrospective, multicenter cohort study from 14 hospitals in Saudi Arabia. We included critically ill COVID-19 patients admitted to the ICU between March 1, 2020, and October 31, 2020. The primary outcome was 28-day ICU mortality. Secondary outcomes were 90-day mortality and ICU length of stay. The predictors of mortality were identified using two predictive models, the conventional logistic regression and DT analysis.Results:A total of 1468 critically ill COVID-19 patients were included. The mean age was 55.9 (SD±15.1) years, with 74% of the patients were males. The 28-day ICU mortality was 540 (36.8%), while 90-day mortality was 600 (40.9%). The multivariable logistic regression model demonstrated that the PaO2/FiO2 ratio on ICU admission and the need for intubation or vasopressors could strongly predict 28-day ICU mortality. The DT algorithm identified five variables [need for intubation, need for vasopressors, age, gender, and PaO2/FiO2 ratio] provided in an algorithmic fashion to predict 28-day ICU outcome. Conclusion:Five clinical predictors of 28-day ICU outcome were identified using DT algorithmic analysis of COVID-19 patients admitted to ICU. The findings of this DT analysis may be used in ICU for early identification of critically ill COVID-19 patients who are at high risk of 28-day mortality.

Pediatric intensive care hybrid-style clinical round during COVID-19 pandemic: A pilot study (preprint)

BackgroundWith the evolving COVID-19 pandemic and the emphasis on social distancing to decrease the spread of SARS-CoV-2 among healthcare workers (HCWs), our pediatric intensive care unit (PICU) piloted utilization of Zoom online into the clinical rounds to enhance communication among the treating team. We aimed to explore the feasibility of these hybrid virtual and physical clinical rounds for PICU patients from the HCWs perspective. MethodsA mixed quantitative and qualitative deductive thematic content analysis of narrative responses from pediatric intensive care HCWs were analyzed, descriptive statistics were used ResultsA total of 31 HCW were included in the analysis; the mean time of the virtual round was 72.45 minutes vs. 34.68 for physical rounds, the most shared component in the virtual round was CXR (93.5%). Some of the HCWs perceived advantages of the hybrid rounds were enabling the multidisciplinary discussions, lesser round interruptions, and practicality of the virtual discussions. The perceived challenges were the difficulty of the bedside nurse to attend the virtual round, decreased teaching opportunities for the trainees, and decreased interactions among the team members, especially if the video streaming was not utilized. ConclusionHybrid virtual and physical clinical rounds in PICU were perceived as feasible by HCWs. The virtual rounds decreased the physical contact between the HCWs, which could decrease the possibility of SARS-CoV-2 spread among the treating team. Still, several components of the hybrid round could be optimized to facilitate the virtual team-members interactions and enhance the teaching experience.

The Saudi Critical Care Society Practice Guidelines on the Management of COVID-19 in the ICU: Therapy Section (preprint)

BackgroundThe rapid increase in coronavirus disease 2019 (COVID-19) cases during the subsequent waves in Saudi Arabia and other countries prompted the Saudi Critical Care Society (SCCS) to put together a panel of experts to issue evidence-based recommendations for the management of COVID-19 in the intensive care unit (ICU).MethodsThe SCCS COVID-19 panel included 51 experts with expertise in critical care, respirology, infectious disease, epidemiology, emergency medicine, clinical pharmacy, nursing, respiratory therapy, methodology, and health policy. All members completed an electronic conflict of interest disclosure form. The panel addressed 9 questions that are related to the therapy of COVID-19 in the ICU. We identified relevant systematic reviews and clinical trials, then used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach as well as the evidence-to-decision framework (EtD) to assess the quality of evidence and generate recommendations.ResultsThe SCCS COVID-19 panel issued 12 recommendations on pharmacotherapeutic interventions (immunomodulators, antiviral agents, and anticoagulants) for severe and critical COVID-19, of which 3 were strong recommendations and 9 were weak recommendations. ConclusionThe SCCS COVID-19 panel used the GRADE approach to formulate recommendations on therapy for COVID-19 in the ICU. The EtD framework allows adaptation of these recommendations in different contexts. The SCCS guideline committee will update recommendations as new evidence becomes available.
