Factors associated with revisits by patients with SARS-CoV-2 infection discharged from a hospital emergency department.

Emergencias 2020 Nov;32(6):386-394

Área de Urgencias, Hospital Clinic, Universitat de Barcelona, España.

Objectives: To analyze emergency department (ED) revisits from patients discharged with possible coronavirus disease 2019 (COVID-19).

Material And Methods: Retrospective observational study of consecutive patients who came to the ED over a period of 2 months and were diagnosed with possible COVID-19. We analyzed clinical and epidemiologic variables, treatments given in the ED, discharge destination, need to revisit, and reasons for revisits. Patients who did or did not revisit were compared, and factors associated with revisits were explored.

Results: The 2378 patients included had a mean age of 57 years; 49% were women. Of the 925 patients (39%) discharged, 170 (20.5%) revisited the ED, mainly for persistence or progression of symptoms. Sixty-six (38.8%) were hospitalized. Odds ratios (ORs) for the following factors showed an association with revisits: history of rheumatologic disease (OR, 2.97; 95% CI, 1.10-7.99; P = .03), digestive symptoms (OR, 1.73; 95% CI, 1.14-2.63; P = .01), respiratory rate over 20 breaths per minute (OR, 1.03; 95% CI, 1.0-1.06; P = .05), and corticosteroid therapy given in the ED (OR, 7.78; 95% CI, 1.77-14.21, P = .01). Factors associated with hospitalization after revisits were age over 48 years (OR, 2.57; 95% CI, 1 42-4.67; P = .002) and fever (OR, 4.73; 95% CI, 1.99-11.27; P = .001).

Conclusion: Patients under the age of 48 years without comorbidity and with normal vitals can be discharged from the ED without fear of complications. A history of rheumatologic disease, fever, digestive symptoms, and a respiratory rate over 20 breaths per minute, or a need for corticosteroid therapy were independently associated with revisits. Fever and age over 48 years were associated with a need for hospitalization.

Methicillin-susceptible staphylococcus aureus in community-acquired pneumonia: Risk factors and outcomes.

J Infect 2021 Jan 2;82(1):76-83. Epub 2020 Nov 2.

Objectives: We aimed to describe the prevalence, risk factors and outcomes of Methicillin-susceptible S. aureus (MSSA) community-acquired pneumonia (CAP) and compare them with those associated with CAP due to Streptococcus pneumoniae, the most frequent causative microorganism, in a large cohort of patients.

Methods: This was an observational study of prospectively collected data of consecutive adults with CAP and a definitive etiology enrolled between 2004 and 2018. Patients were divided into MSSA CAP and pneumococcal CAP groups for analysis.

Results: A microbial etiology was established in 1,548 (33%) cases: S. aureus caused 6% of microbiologically-confirmed CAP cases. In the latter, 52 were due to MSSA (60% of S. aureus CAP cases, and 3% of microbiologically-confirmed CAP cases) and 34 were due to MRSA (40% of S. aureus CAP cases, and 2% of microbiologically-confirmed CAP cases). S. pneumoniae was identified in 734 (47%) microbiologically-confirmed CAP cases. The presence of fever was independently associated with a lower risk of MSSA CAP (OR 0.53; 95% CI, 0.28-0.99). Patients with MSSA CAP had higher 30-day mortality than patients with pneumococcal CAP, both before and after adjustment for potential confounders (21% vs 7%, p = 0.002). MSSA was independently associated with 30-day mortality in the overall population.

Conclusion: MSSA CAP was associated with worse outcomes than pneumococcal CAP in our cohort. MSSA was an independent factor of mortality.
