Complicated intra-abdominal infections in a worldwide context: an observational prospective study (CIAOW Study). World J Emerg Surg. 2013; 8(1):1http://hdl.handle.net/10668/864Journal Article;Despite advances in diagnosis, surgery, and antimicrobial therapy, mortality rates associated with complicated intra-abdominal infections remain exceedingly high. The World Society of Emergency Surgery (WSES) has designed the CIAOW study in order to describe the clinical, microbiological, and management-related profiles of both community- and healthcare-acquired complicated intra-abdominal infections in a worldwide context. The CIAOW study (Complicated Intra-Abdominal infection Observational Worldwide Study) is a multicenter observational study currently underway in 57 medical institutions worldwide. The study includes patients undergoing surgery or interventional drainage to address complicated intra-abdominal infections. This preliminary report includes all data from almost the first two months of the six-month study period. Patients who met inclusion criteria with either community-acquired or healthcare-associated complicated intra-abdominal infections (IAIs) were included in the study. 702 patients with a mean age of 49.2 years (range 18-98) were enrolled in the study. 272 patients (38.7%) were women and 430 (62.3%) were men. Among these patients, 615 (87.6%) were affected by community-acquired IAIs while the remaining 87 (12.4%) suffered from healthcare-associated infections. Generalized peritonitis was observed in 304 patients (43.3%), whereas localized peritonitis or abscesses was registered in 398 (57.7%) patients.The overall mortality rate was 10.1% (71/702). The final results of the CIAOW Study will be published following the conclusion of the study period in March 2013.enInfecciones IntraabdominalesEstudio MulticéntricoAbsceso AbdominalEnfermedad CríticaHumanosDrenajeProcedimientos Quirúrgicos del Sistema DigestivoFarmacoresistencia microbianaReoperaciónInfección HospitalariaAdultoMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Infection::Intraabdominal InfectionsMedical Subject Headings::Publication Characteristics::Study Characteristics::Multicenter StudyMedical Subject Headings::Diseases::Digestive System Diseases::Peritoneal Diseases::PeritonitisMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Infection::Suppuration::Abscess::Abdominal AbscessMedical Subject Headings::Diseases::Pathological Conditions, Signs and Symptoms::Pathologic Processes::Disease Attributes::Critical IllnessMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Surgical Procedures, Operative::DrainageMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Surgical Procedures, Operative::Digestive System Surgical ProceduresMedical Subject Headings::Phenomena and Processes::Microbiological Phenomena::Drug Resistance, MicrobialMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Infection::SepsisMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Surgical Procedures, Operative::ReoperationMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Infection::Cross InfectionMedical Subject Headings::Named Groups::Persons::Age Groups::Adultresearch article23286785open access10.1186/1749-7922-8-11749-7922PMC3538624PMC3538624
