RESUMEN
INTRODUCTION: In 2020, patients with critical coronavirus disease 2019 (COVID-19) had a 28-day mortality rate of 30% to 50% worldwide; outcomes among such patients in Hong Kong were unknown. This study investigated 28-day mortality and corresponding risk factors among patients with severe or critical COVID-19 in Hong Kong. METHODS: This retrospective cohort study included adult patients with severe or critical COVID-19 who were admitted to three public hospitals in Hong Kong from 22 January to 30 September 2020. Demographics, comorbidities, symptoms, treatment, and outcomes were examined. RESULTS: Among 125 patients with severe or critical COVID-19, 15 (12.0%) died within 28 days. Overall, the median patient age was 64 years; 48.0% and 54.4% of patients had hypertension and obesity, respectively. Respiratory samples were confirmed severe acute respiratory syndrome coronavirus 2 RNA-positive after a median of 3 days. The most common presenting symptom was fever (80.0% of patients); 45.6% and 32.8% of patients received care in intensive care unit and required mechanical ventilation, respectively. In logistic regression analysis comparing 28-day survivors and non-survivors, factors associated with greater 28-day mortality were older age (odds ratio [OR] per 1-year increase in age=1.12, 95% confidence interval [CI]=1.04-1.21; P=0.002), history of stroke (OR=15.96, 95% CI=1.65-154.66; P=0.017), use of renal replacement therapy (OR=15.32, 95% CI=2.67-87.83; P=0.002), and shorter duration of lopinavir-ritonavir treatment (OR per 1-day increase=0.82, 95% CI=0.68-0.98; P=0.034). CONCLUSION: The 28-day mortality rate among patients with severe or critical COVID-19 in Hong Kong was 12.0%. Older age, history of stroke, use of renal replacement therapy, and shorter duration of lopinavir-ritonavir treatment were independent predictors of 28-day mortality.

PURPOSE: Streptococcus pneumoniae is a common pathogen involved in community-acquired pneumonia. Invasive pneumococcal disease is often associated with higher co-morbidity rates, but mortality-related findings have been inconclusive. This study investigated predictors of 30-day mortality and invasive pneumococcal disease. METHODS: This retrospective analysis included adults with pneumococcal disease who were admitted to Pamela Youde Nethersole Eastern Hospital from 1 January 2011 to 31 December 2018. Demographics, microbiological characteristics, and outcomes were compared between 30-day survivors and non-survivors, and between patients with invasive disease and those with non-invasive disease. Intensive care unit (ICU) subgroup analysis was performed. The primary outcome was 30-day all-cause mortality; secondary outcomes were ICU and hospital mortalities, and ICU and hospital lengths of stay. RESULTS: In total, 792 patients had pneumococcal disease; 701 survived and 91 (11.5%) died within 30 days. Notably, 106 (13.4%) patients had invasive pneumococcal disease and 170 (21.5%) patients received intensive care. Vasopressor use (odds ratio [OR]=4.96, P<0.001), chronic kidney disease (OR=3.62, P<0.001), positive urinary antigen test results (OR=2.57, P=0.001), and advanced age (OR=2.19, P=0.010) were independent predictors for 30-day mortality by logistic regression analysis. Among critically ill patients, chronic kidney disease (OR=4.64, P<0.001), higher APACHE IV score (OR=3.73, P=0.016), and positive urinary antigen test results (OR=2.94, P=0.008) were predictors for 30-day mortality. Logistic regression analysis revealed that chronic kidney disease (OR=3.10, P<0.001) was a risk factor for invasive pneumococcal disease. CONCLUSION: Advanced age, vasopressor use, chronic kidney disease, and positive urinary antigen test results were independent predictors for 30-day mortality in patients with pneumococcal disease.
