Objective: Spain is one of the European countries most affected by the COVID-19 pandemic. Epidemiologic studies are warranted to improve the disease understanding, evaluate the care procedure and prepare for futures waves. The aim of the study was to describe epidemiologic characteristics associated with hospitalized patients with COVID-19., Methods: This real-world, observational, multicenter and retrospective study screened all consecutive patients admitted to 8 Spanish private hospitals. Inclusion criteria: hospitalized adults (age≥18 years old) with clinically and radiologically findings compatible with COVID-19 disease from March 1st to April 5th, 2020. Exclusion criteria: patients presenting negative PCR for SARS-CoV-2 during the first 7 days from hospital admission, transfer to a hospital not belonging to the HM consortium, lack of data and discharge against medical advice in emergency departments., Results: One thousand and three hundred thirty-one COVID-19 patients (medium age 66.9 years old; males n= 841, medium length of hospital stayed 8 days, non-survivors n=233) were analyzed. One hundred and fifteen were admitted to intensive care unit (medium length of stay 16 days, invasive mechanical ventilation n= 95, septic shock n= 37 and renal replacement therapy n= 17). Age, male gender, leukocytes, platelets, oxygen saturation, chronic therapy with steroids and treatment with hydroxychloroquine/azithromycin were independent factors associated with mortality. The proportion of patients that survive and received tocilizumab and steroids were lesser and higher respectively than those that die, but their association was not significant., Conclusions: Overall crude mortality rate was 17.5%, rising up to 36.5% in the subgroup of patients that were admitted to the intensive care unit. Seven factors impact in hospital mortality. No immunomodulatory intervention were associated with in-hospital mortality., (©The Author 2021. Published by Sociedad Española de Quimioterapia.

Objective: The aims of the study were: to develop a predictive model for hospital mortality and another for hospital re-admission, to identify the impact of antibiotic delay in the mortality rate and, to report the rate of inappropriate antibiotic therapy., Methods: A cohort and retrospective study was conducted at the HM Sanchinarro University Hospital during the period September 1st, 2012 to March 31th, 2013. The inclusion criteria were: age> 18 years, hospital admission from the ED with a diagnosis of bacterial infection. The exclusion criteria were: suspected viral infection, negative bacteriological cultures, life expectancy less than 6 months, lack of clinical information, assistance exclusively by the trauma emergency department. Two logistic models were made (hospital mortality and hospital re-admission)., Results: A total of 517 patients were included. The final mortality model (30 deaths) include the following variables: respiratory rate (OR 1.12; IC95% 1.02; 1.22), oxygen saturation (OR 0.92; IC95% 0.87; 0.98), creatinine (OR 2.33; IC95% 1.62; 3.36), COPD (OR 3.02; IC95% 1.06; 8.21), cancer (OR 3.34; IC95% 1.07; 9.98) and chemotherapy in the last 3 months (OR 4.83; IC95% 1.54; 16.41). The final model for hospital re-admission (28 re-admissions) include the following variables: hepatopathy (OR 5.51; IC95% 1.57; 16.88), GPT (OR 1.005; IC95% 1.003; 1.008), history of stroke (OR 5.06; IC95% 1.04; 18.80) and arterial hypertension (OR 3.15; IC95% 1.38; 7.56). The antibiotic therapy delays not influenced the mortality or re-admission rate. In 24.3% the causative microorganism was identified and antibiotic treatment was inappropriate 19.6%., Conclusions: Hospital mortality rate was 5.8% and readmission rate was 5.7%. Variables associated with mortality differ from those associated with re-admission. The delay in the antibiotic initiation was not associated with a deleterious effect. Antibiotic therapy was inadequate in almost 20% of patients., (©The Author 2020. Published by Sociedad Española de Quimioterapia.
