Increase in hospital care at the end of life: Retrospective analysis of the last 20 years of life of a cohort of patients.

Background: There is an increasing need for end-of-life care due to society's progressive aging. This study aimed to describe how hospitalizations evolve long-term and in the last months life of a cohort of deceased patients.

Methods: The study population were those who died in one year who lived in a district in southern Spain.

Nosocomial COVID-19: A Nationwide Spanish Study.

Introduction: SARS-CoV-2 is a highly contagious virus, and despite professionals' best efforts, nosocomial COVID-19 (NC) infections have been reported. This work aimed to describe differences in symptoms and outcomes between patients with NC and community-acquired COVID-19 (CAC) and to identify risk factors for severe outcomes among NC patients.

Methods: This is a nationwide, retrospective, multicenter, observational study that analyzed patients hospitalized with confirmed COVID-19 in 150 Spanish hospitals (SEMI-COVID-19 Registry) from March 1, 2020, to April 30, 2021.

Remdesivir in Very Old Patients (≥80 Years) Hospitalized with COVID-19: Real World Data from the SEMI-COVID-19 Registry.

(1) Background: Large cohort studies of patients with COVID-19 treated with remdesivir have reported improved clinical outcomes, but data on older patients are scarce. Objective: This work aims to assess the potential benefit of remdesivir in unvaccinated very old patients hospitalized with COVID-19; (2) Methods: This is a retrospective analysis of patients ≥ 80 years hospitalized in Spain between 15 July and 31 December 2020 (SEMI-COVID-19 Registry). Differences in 30-day all-cause mortality were adjusted using a multivariable regression analysis.

Coronavirus disease 2019 hospitalization outcomes in persons with and without HIV in Spain.

Objective: To compare coronavirus disease 2019 (COVID-19) hospitalization outcomes between persons with and without HIV.

Design: Retrospective observational cohort study in 150 hospitals in Spain.

Methods: Patients admitted from 1 March to 8 October 2020 with COVID-19 diagnosis confirmed by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 positive) PCR test in respiratory tract samples.

Risk Categories in COVID-19 Based on Degrees of Inflammation: Data on More Than 17,000 Patients from the Spanish SEMI-COVID-19 Registry.

(1) Background: The inflammation or cytokine storm that accompanies COVID-19 marks the prognosis. This study aimed to identify three risk categories based on inflammatory parameters on admission. (2) Methods: Retrospective cohort study of patients diagnosed with COVID-19, collected and followed-up from 1 March to 31 July 2020, from the nationwide Spanish SEMI-COVID-19 Registry.

Inappropriate antibiotic use in the COVID-19 era: Factors associated with inappropriate prescribing and secondary complications. Analysis of the registry SEMI-COVID.

Background: Most patients with COVID-19 receive antibiotics despite the fact that bacterial co-infections are rare. This can lead to increased complications, including antibacterial resistance. We aim to analyze risk factors for inappropriate antibiotic prescription in these patients and describe possible complications arising from their use.

Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry.

Aim: To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW).

Methods: Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected.

Severity Scores in COVID-19 Pneumonia: a Multicenter, Retrospective, Cohort Study.

Background: Identification of patients on admission to hospital with coronavirus infectious disease 2019 (COVID-19) pneumonia who can develop poor outcomes has not yet been comprehensively assessed.

Objective: To compare severity scores used for community-acquired pneumonia to identify high-risk patients with COVID-19 pneumonia.

Design: PSI, CURB-65, qSOFA, and MuLBSTA, a new score for viral pneumonia, were calculated on admission to hospital to identify high-risk patients for in-hospital mortality, admission to an intensive care unit (ICU), or use of mechanical ventilation.

Association of Hypertension with All-Cause Mortality among Hospitalized Patients with COVID-19.

It is unclear to which extent the higher mortality associated with hypertension in the coronavirus disease (COVID-19) is due to its increased prevalence among older patients or to specific mechanisms. Cross-sectional, observational, retrospective multicenter study, analyzing 12226 patients who required hospital admission in 150 Spanish centers included in the nationwide SEMI-COVID-19 Network. We compared the clinical characteristics of survivors versus non-survivors.

[Prognostic factors and long-term survival after initial diagnosis of heart failure].

Background And Objective: To assess long-term mortality and prognostic factors after initial diagnosis of heart failure (HF), to analyze the differences in function of the left ventricular ejection fraction (preserved [HFPEF] vs. systolic dysfunction [HFSD]) and to compare the results with the main series of incident cases of HF published.

Patients And Methods: Retrospective cohort study including patients first diagnosed of heart failure (Framingham criteria), between 1-01-1997 and 31-12-2001, classified according to a left ventricle ejection fraction (LVEF) above or equal to 50% (HFPEF) or below 50% (HFSD).
