Pooled analysis of who surgical safety checklist use and mortality after emergency laparotomy

Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients incl…

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the Globa…

Global economic burden of unmet surgical need for appendicitis

Abstract Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capita…

Modèle d'analyse locorégional des systèmes énergétiques

National audience; RÉSUMÉ : le défi majeur qui se pose aujourd'hui à tout acteur du système énergétique est de rendre compte des rapports, à la fois contradictoires et simultanés, entre mondialisation et décentralisation, d'une part, et entre développement socioéconomique et développement durable, d'autre part. Ce défis doit être abordé par une approche globale, seule capable d'appréhender toute la complexité du problème, induite par les interactions des facteurs socio-économiques, politiques, technologiques et environnementaux. Cette approche doit être menée en replaçant le système énergétique dans un cadre territorial permettant de saisir les logiques et les implications spatiales des dif…
