ABSTRACT
Background@#The rapid increase in the number of coronavirus disease (COVID-19) patients led to the operation of COVID-19 facilities for patients with mild COVID-19 in South Korea. We analyzed the correlation and effect of risk factors associated with the worsening of patients with mild COVID-19 leading to their transfer from a community treatment center to a hospital. @*Methods@#This retrospective cohort observational study included 1,208 COVID-19 patients with mild symptoms who were admitted to the Namsan Community Treatment Center between June 2020 and January 2021. A chi-square test was performed to examine the differences in the transfer rate by age, sex, nationality, presence of symptoms at admission, and season, and a multivariable logistic regression analysis was performed to examine the association of variables to the hospitalization rate. @*Results@#Of the 1,208 patients, 212 (17.5%) were transferred to a hospital due to clinical deterioration. Increasing odds of hospital transfer were associated significantly with higher age and presentation in autumn, whereas sex and symptomatic illness at admission did not show a statistically significant association. @*Conclusion@#The findings indicate the importance of the initial risk classification of COVID-19 patients based on thorough assessment and close monitoring, timely allocation of appropriate resources to high-risk groups that are likely to develop severe disease, and reduction of medical resource wastage and limiting of administrative force to ensure that patients receive the best treatment.
ABSTRACT
Objective@#Practice guidelines for diverticulitis have been developed in countries where left-colon diverticulitis is dominant,but there is limited information on right-colon diverticulitis. This study examined the clinical characteristics and riskfactors of clinically severe right-colon diverticulitis. @*Methods@#A retrospective chart review of patients diagnosed with diverticulitis in an emergency department in Koreabetween 2013 and 2017 was performed. Clinically severe diverticulitis was defined as any cause of death, intensive careunit admission, surgery, or invasive intervention due to diverticulitis, and admission for seven or more hospital days.Multivariable logistic regression was used to identify the risk factors for clinically severe diverticulitis. @*Results@#This study analyzed 302 patients. Patients with older age (odds ratio [OR], 1.044; 95% confidence interval [CI],1.009-1.080; P=0.013), complications observed on computed tomography (CT) (OR, 6.906; 95% CI, 2.514-18.968;P<0.001), rebound tenderness on a physical examination (OR, 2.542; 95% CI, 1.041-6.218; P=0.041), high alkalinephosphatase (ALP) levels (OR, 1.014; 95% CI, 1.002-1.026; P=0.026), and high C-reactive protein (CRP) levels (OR,1.095; 95% CI, 1.017-1.178; P=0.013) were at higher risk of clinically severe diverticulitis. @*Conclusion@#Among patients diagnosed with right-colon diverticulitis in the emergency department, those of older age,distinct complications on CT, rebound tenderness on physical examination, high ALP, and high CRP levels are related toclinically severe disease.
