A comparison of three thromboprophylaxis regimens in critically ill COVID-19 patients: An analysis of real-world data.

Introduction: Thrombotic complications of coronavirus disease 2019 (COVID-19) have received considerable attention. Although numerous conflicting findings have compared escalated thromboprophylaxis doses with a standard dose to prevent thrombosis, there is a paucity of literature comparing clinical outcomes in three different anticoagulation dosing regimens. Thus, we investigated the effectiveness and safety profiles of standard, intermediate, and high-anti-coagulation dosing strategies in COVID-19 critically ill patients. Methodology: This retrospective multicenter cohort study of intensive care unit (ICU) patients from the period of April 2020 to August 2021 in four Saudi Arabian centers. Inclusion criteria were age ≥ 18 years, diagnosis with severe or critical COVID-19 infection, and receiving prophylactic anticoagulant dose within 24-48 h of ICU admission. The primary endpoint was a composite of thrombotic events, with mortality rate and minor or major bleeding serving as secondary endpoints. We applied survival analyses with a matching weights procedure to control for confounding variables in the three arms. Results: A total of 811 patient records were reviewed, with 551 (standard-dose = 192, intermediate-dose = 180, and high-dose = 179) included in the analysis. After using weights matching, we found that the standard-dose group was not associated with an increase in the composite thrombotic events endpoint when compared to the intermediate-dose group {19.8 vs. 25%; adjusted hazard ratio (aHR) =1.46, [95% confidence of interval (CI), 0.94-2.26]} or when compared to high-dose group [19.8 vs. 24%; aHR = 1.22 (95% CI, 0.88-1.72)]. Also, there were no statistically significant differences in overall in-hospital mortality between the standard-dose and the intermediate-dose group [51 vs. 53.4%; aHR = 1.4 (95% CI, 0.88-2.33)] or standard-dose and high-dose group [51 vs. 61.1%; aHR = 1.3 (95% CI, 0.83-2.20)]. Moreover, the risk of major bleeding was comparable in all three groups [standard vs. intermediate: 4.8 vs. 2.8%; aHR = 0.8 (95% CI, 0.23-2.74); standard vs. high: 4.8 vs. 9%; aHR = 2.1 (95% CI, 0.79-5.80)]. However, intermediate-dose and high-dose were both associated with an increase in minor bleeding incidence with aHR = 2.9 (95% CI, 1.26-6.80) and aHR = 3.9 (95% CI, 1.73-8.76), respectively. Conclusion: Among COVID-19 patients admitted to the ICU, the three dosing regimens did not significantly affect the composite of thrombotic events and mortality. Compared with the standard-dose regimen, intermediate and high-dosing thromboprophylaxis were associated with a higher risk of minor but not major bleeding. Thus, these data recommend a standard dose as the preferred regimen.

Pediatric urology surgical practice in the time of COVID-19: Results from tertiary Saudi Arabia hospitals.

PURPOSE: Our study aimed to evaluate the effect of COVID-19 on pediatric urology practice in the Kingdom of Saudi Arabia (KSA). METHODS: Data of 10 tertiary hospitals in KSA were retrospectively analyzed. Data of outpatient department (OPD) visits and pediatric urology surgical procedures from January 1, 2019, to April 30, 2019, and from January 1, 2020, to April 30, 2020, were extracted. The primary outcome was to compare OPD visits and pediatric urology workload in the first third of 2020 versus 2019, where there was no curfew. The secondary outcome was to compare the same variables during the full curfew time, i.e., April 2020 versus April 2019. RESULTS: The number of OPD visits was lower in the first third of 2020 (7390 vs. 10,379 in 2019 P < 0.001). OPD visits in April 2020 were 78.6% lower than in April 2019, and teleclinics represented 850 (94.3%). Elective procedures in the first third of 2020 were 688, with a reduction rate of 34.3% compared to the same period of 2019 (P < 0.001). In April 2020, there were 18 elective surgeries, with a 91.4% decrease than in April 2019. Ureteric reimplantation, hypospadias, cryptorchidism, and circumcision stopped, while pyeloplasty (n = 14) and urolithiasis (n = 4) procedures had declined by 50% and 76.5%, respectively. Most of the procedures (71.8%) were day surgery. Emergency procedures were similar in the first third of 2020 (65 vs. 64 in 2019, P = 0.994) and declined in April 2020 by 6.7% versus April 2019. During the full curfew, the most common emergency intervention were cases with obstructive uropathy (42.8%), followed by torsion testis (28.6%), posterior urethral valve (14.3%), and urological trauma (14.3%). CONCLUSIONS: In KSA, the number of elective pediatric surgical procedures were reduced by >90%, while the number of emergency pediatric surgical procdures were similar during COVID-19 pandemic compared with non-COVID-19 time. Ureteric reimplantation, hypospadias repair, cryptorchidism, and circumcision procedures were postponed. Pyeloplasty and urolithiasis-related procedures were performed to prevent irreversible disease progression or organ damage. There was an increase in rate of teleclinic and day surgery to reduce the risk of COVID-19 infection.

Kuwaiti hospital patients' continuance intention to use telemedical systems in the wake of the COVID19 pandemic.

The objective of this study is to investigate factors influencing patients' continuance intention to use telemedicine after the COVID-19 pandemic in the medical sector of Kuwait. To reach this purpose, the updated Delone and Maclean (2003) model was utilized to investigate the aforementioned factors. As such, this research applied quantitative research methods with a sample of 290 participants from patients in Dar Al Shifa Hospital, a private hospital in Kuwait which utilizes telemedical services called 'Sehaty online'. The corresponding data was analyzed using SmartPLS. The findings of this study revealed that information quality and system quality have a positive and significant influence on patient's satisfaction, whereas service quality has an insignificant influence on patient's satisfaction. Also, patients' continuance intention to use telemedicine is found to be significantly impacted by their satisfaction. Furthermore, several limitations of the study, related future research, and recommendations have been discussed.

A Novel Framework for Facilitating Emergency Remote Learning during the COVID-19 Pandemic

In today's educational landscape educators and administrators are confronted with unprecedented challenges as they have to hastily move education online. Emergency remote teaching is a response to this crisis. However, the research about the efficacy of remote teaching is scarce because of COVID-19 which is a rapidly evolving situation and also because of a lack of clarity about what constitutes instruction during an emergency. Moreover, the actual practices for emergency remote teaching are unclear in the context of Kuwait. This study aims to investigate how educators are implementing emergency remote instruction in order to reshape education during the COVID-19 pandemic in Kuwait where traditional instructional approaches and practices are dominant. Using a case study research design, the researchers delve into educators' perspectives by collecting qualitative data from interviews. The results indicate that educators used multiple pedagogical approaches to enhance student participation and learning. It also revealed the problematic aspects of remote or distance education. Finally, the results were used to construct and present a Novel Remote Learning Framework, which is an empirically-grounded, theoretically-informed conceptualization of emergency remote instruction which is expected to reshape instruction during the COVID-19 pandemic.
