Clinical characteristics and laboratory biomarkers changes in COVID-19 patients requiring or not intensive or sub-intensive care: a comparative study

Abstract Background Identifying risk factors for severe novel-coronavirus disease (COVID-19) is useful to ascertain which patients may benefit from advanced supportive care. The study aims to offer a comparative description of the COVID-19 patients, admitted to a general ward for a non-critical clinical picture, who required or not to be transferred to the intensive (ICU) and/or sub-intensive care (SICU) units. Methods This observational retrospective study included all COVID-19 patients admitted to the Infectious Diseases Unit. Clinical, laboratory, radiological and treatment data were collected. The primary outcome was a composite of need of transfer to the ICU and/or SICU during the hospitalization. Patients who did not require to be transferred are defined Group 1; patients who were transferred to the ICU and/or SICU are defined Group 2. Demographic and clinical characteristics were compared between the two groups. Results 303 patients were included. Median age was 62 years. 69 patients (22,8%) met the primary outcome and were defined Group 2. The overall mortality rate was 6.8%. Group 2 were more likely to be men, had a higher mortality (14,5% vs. 3,8%, p<0,01), had more hypertension (72,4% vs. 44%, p<0,01) and diabetes (31,9% vs. 21%, p=0,04) and were more likely to present dry cough (49,3% vs. 25,2%, p<0.01). Overall, chest X-ray at admission showed findings suggestive of pneumonia in 63,2%, and Group 2 were more likely to develop pathological findings during the hospitalization (72,7%vs. 17,2%, p<0,01). At admission, Group 2 presented significantly higher neutrophil count, aspartate-transaminase and C-reactive-protein. At the 3rd measurement, Group 2 presented persistently higher neutrophil count, liver function tests and C-reactive-protein. Group 1 presented a shorter duration from admission to negativization of follow-up swabs (20 vs. 35 days, p<0,01). Conclusions The presence of comorbidities and the persistent observation of abnormal laboratory findings should be regarded as predisposing factors for clinical worsening..
