First wave of the COVID-19 pandemic in Madrid: handling the unexpected in a tertiary hospital.

Introduction: The COVID-19 pandemic was declared on March 11, 2020. By the end of January, the first imported cases were detected in Spain and, by March, the number of cases was growing exponentially, causing the implementation of a national lockdown. Madrid has been one of the most affected regions in terms of both cases and deaths.

Carbapenem-Resistant Enterobacteriaceae Outbreak in a Medical Ward in Spain: Epidemiology, Control Strategy, and Importance of Environmental Disinfection.

Carbapenem-resistant Enterobacteriaceae (CRE) are a growing public health problem. We describe an outbreak by CRE and the measures to control it in a hospitalization unit in Spain. In June 2015, the system of prevention and control of CRE implemented in the hospital detected an increase in the incidence of patients with CRE in a mixed hospitalization facility (geriatrics, internal medicine, and pneumology), with the appearance of four related patients in 2 weeks, three of them being nosocomial cases.

Serratia marcescens outbreak in a neonatology unit of a Spanish tertiary hospital: Risk factors and control measures.

Background: We describe the investigation undertaken and the measures adopted to control a Serratia marcescens outbreak in the neonatology unit of La Paz University Hospital in Madrid, Spain.

Methods: Weekly rectal and pharyngeal screenings for S marcescens were performed in the neonates starting after detection of the outbreak. Environmental samples and samples from health care workers (HCWs) were obtained for microbiological analysis.

[Implementation of a post-discharge surgical site infection system in herniorrhaphy and mastectomy procedures].

Introduction: Monitoring surgical site infection (SSI) performed during hospitalization can underestimate its rates due to the shortening in hospital stay. The aim of this study was to determine the actual rates of SSI using a post-discharge monitoring system.

Methods: All patients who underwent herniorraphy or mastectomy in the Hospital Universitario Ramón y Cajal from 1 January 2011 to 31 December 2011 were included.

[Trends in the prevalence of extended-spectrum beta-lactamase-producing gram-negative bacilli in a teaching hospital in Madrid, Spain].

Background And Objective: The pprevalence of extended-spectrum beta-lactamase (ESBL) producing gram-negative bacilli has increased in recent years. The aim of this study is to estimate the prevalence of infection/colonization due to theses microorganisms per 100 admissions and its trend during the period 2007-2010.

Patients And Methods: Prospective observational study of all patients admitted from January 2007 to December 2010 infected or colonized with ESBL-producing gram-negative bacilli at Hospital Universitario Ramón y Cajal.

[Preoperative preparation, antibiotic prophylaxis and surgical wound infection in breast surgery].

Introduction: The impact of surgical wound infection on public health justifies its surveillance and prevention. Our objectives were to estimate the incidence of surgical wound infection in breast procedures and assess its protocol of antibiotic prophylaxis and preoperative preparation.

Methods: Observational multicentre prospective cohort study of incidence of surgical wound infection.

[Assessment of the surgical site infection in 14 hospitals of the Madrid Region: an incidence study].

Background And Objectives: Health care-associated infections (HAIs) occur frequently in hospitals and have severe consequences, with surgical site infection (SSI) being one of the most commonly reported. The aim of this study was to determine SSI rates and to asses the application of presurgical preparation and antimicrobial prophylaxis protocols in 14 public hospitals of the region of Madrid.

Material And Methods: Multi-centre prospective surveillance study.
