Prevalence, Causes, and Adverse Clinical Impact of Delayed Presentation of Non-COVID-19-Related Emergencies during the COVID-19 Pandemic: Findings from a Multicenter Observational Study

Changes in Etiology and Clinical Outcomes of Pleural empyema during the COVID-19 Pandemic

Healthcare-seeking behavior changed during the COVID-19 pandemic and might alter the epidemiology of pleural empyema. In this study, the incidence, etiology and outcomes of patients admitted for pleural empyema in Hong Kong in the pre-COVID-19 (January 2015-December 2019) and post-COVID-19 (January 2020-June 2022) periods were compared. Overall, Streptococcus pneumoniae was the predominant organism in <18-year-old patients, while Streptococcus anginosus, anaerobes and polymicrobial infections were more frequent in adults. In the post-COVID-19 period, a marked decline in the incidence of pleural empyema in children was observed (pre-COVID-19, 18.4 ± 4.8 vs. post-COVID-19, 2.0 ± 2.9 cases per year, p = 0.036), while the incidence in adults remained similar (pre-COVID-19, 189.0 ± 17.2 vs. post-COVID-19, 198.4 ± 5.0 cases per year; p = 0.23). In the post-COVID-19 period, polymicrobial etiology increased (OR 11.37, p < 0.0001), while S. pneumoniae etiology decreased (OR 0.073, p < 0.001). In multivariate analysis, clinical outcomes (length of stay, ICU admission, use of intrapleural fibrinolytic therapy, surgical intervention, death) were not significantly different in pre- and post-COVID-19 periods. In conclusion, an increase in polymicrobial pleural empyema was observed during the pandemic. We postulate that this is related to the delayed presentation of pneumonia to hospitals.

The Effect of COVID-19 Lockdown on Cerebrovascular Accidents, Acute Coronary Syndrome, and Diabetic Ketoacidosis Visits the Emergency Department: A Retrospective Study

Objective This study aims to assess the effect of the COVID-19 lockdown on acute coronary syndrome (ACS), cerebrovascular accident (CVA), and diabetic ketoacidosis (DKA) visits the emergency department (ED). Methods We compared two groups of patients attending King Abdulaziz University Hospital (KAUH) ED diagnosed with one of the following ACS, CVA, or DKA; patients presenting from 21 December 2019 to 23 March 2020 and patients presenting from 23 March 2020 to 21 June 2020, representing COVID-19 pre-lockdown and during-lockdown period, respectively. The variables we analyzed were age, nationality (Saudi/non-Saudi), and gender. Results Our total sample size was 285 patient visits, ACS (n=130), CVA (n=98), and DKA (n=57). Results showed a statistically significant relationship between the number of patients with ACS and the period of visitation to ED (45.24% reduction, p-value <0.001), while CVA (18.5% reduction, p-value 0.312) and DKA (16% reduction, p-value 0.508) showed no statistically significant relationship. Conclusion A lockdown may be necessary to control a pandemic. However, it may carry potential collateral damage, such as a decrease and delay in the presentation of life-threatening conditions, which may lead to worsening outcomes. A clinical presentation of these conditions should warrant comprehensive evaluation by healthcare workers regardless of an ongoing pandemic while implementing infection control guidelines.
