The cost of infection in hip arthroplasty: a matched case-control study.

Objective: Surgical site infection (SSI) represents 30% of all causes of health care-associated infection (HAI) and is one of the most dreaded complications in surgical patients. We estimated the excess direct costs of SSI using a matched nested case-control study in acute-term care at Ramon y Cajal University Hospital in Spain.

Material And Method: Cases were patients who developed a first episode of SSI according to the criteria established by the CDC's National Healthcare Safety Network.

Surgical wound infection rates in Spain: data summary, January 1997 through June 2012.

Background: The Indicadores Clínicos de Mejora Continua de la Calidad (INCLIMECC) program was established in Spain in 1997.

Methods: INCLIMECC is a prospective system of health care-associated infection (HAI) surveillance that collects incidence data in surgical and intensive care unit patients. The protocol is based on the National Healthcare Safety Network (NHSN) surveillance system, formerly known as the National Nosocomial Infection Surveillance (NNIS) system, and uses standard infection definitions from the US Centers for Disease Control and Prevention.

[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.

[Factors associated to admission to Intensive Care in patients hospitalized due to pandemic Influenza A/H1N1 2009].

Objective: The present study explores the possible factors related to severe cases of pandemic flu.

Design: A retrospective cohort study was conducted in patients hospitalized with Influenza A/H1N1 2009 during the pandemic period.

Setting: Ramon y Cajal University Hospital (Madrid, Spain).
