Skin and soft-tissue infections (SSTIs) encompass a variety of pathological conditions that involve the skin and underlying subcutaneous tissue, fascia, or muscle, ranging from simple superficial infections to severe necrotizing infections. SSTIs are a frequent clinical problem in surgical departments. In order to clarify key issues in the management of SSTIs, a task force of experts met in Bertinoro, Italy, on June 28, 2018, for a specialist multidisciplinary consensus conference under the auspices of the World Society of Emergency Surgery (WSES) and the Surgical Infection Society Europe (SIS-E). The multifaceted nature of these infections has led to a collaboration among general and emergency surgeons, intensivists, and infectious disease specialists, who have shared these clinical practice recommendations.

Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in hospitals worldwide. The cornerstones of effective treatment of IAIs include early recognition, adequate source control, appropriate antimicrobial therapy, and prompt physiologic stabilization using a critical care environment, combined with an optimal surgical approach. Together, the World Society of Emergency Surgery (WSES), the Global Alliance for Infections in Surgery (GAIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), and the American Association for the Surgery of Trauma (AAST) have jointly completed an international multi-society document in order to facilitate clinical management of patients with IAIs worldwide building evidence-based clinical pathways for the most common IAIs. An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting information was shared by an international task force from 46 countries with different clinical backgrounds. The aim of the document is to promote global standards of care in IAIs providing guidance to clinicians by describing reasonable approaches to the management of IAIs.

To learn about medical students' knowledge of and perspectives on antibiotic prescribing and resistance, with the aim of helping to develop educational programmes. Final-year students at seven European medical schools were invited to participate in an online survey in 2012. The response rate was 35% (338/961). Most students (74%) wanted more education on choosing antibiotic treatments. Students at all schools felt most confident in diagnosing an infection and least confident in choosing combination therapies, choosing the correct dose and interval of administration and not prescribing in cases of diagnostic uncertainty. Students felt that too many prescriptions and too much broad-spectrum antibiotic use were the most important contributors to resistance; some (24%) believed poor hand hygiene was not at all important. Most students (92%) believed that resistance is a national problem. Most (66%) felt that the antibiotics they would prescribe would contribute to resistance, and almost all (98%) felt that resistance would be a greater problem in the future. Most students (83%) incorrectly thought that rates of methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia had significantly increased over the past decade in their countries. There was little appreciation of the relative burden of resistance in Europe compared with road traffic accidents (around two to three times greater mortality) and lung cancer (around 10 times greater mortality). Students wanted further education on antibiotic prescribing, and areas of lack of confidence were found. Students overestimated the current burden of resistant bacteria and were unaware of successes in reducing MRSA infections. Educational and stewardship programmes may benefit from including more cases of diagnostic uncertainty, and highlighting successes such as MRSA prevention, as evidence for the importance of current interventions.

In the last three decades, Clostridium difficile infection (CDI) has increased in incidence and severity in many countries worldwide. The increase in CDI incidence has been particularly apparent among surgical patients. Therefore, prevention of CDI and optimization of management in the surgical patient are paramount. An international multidisciplinary panel of experts from the World Society of Emergency Surgery (WSES) updated its guidelines for management of CDI in surgical patients according to the most recent available literature. The update includes recent changes introduced in the management of this infection.

Antimicrobial resistance (AMR) is a phenomenon resulting from the natural evolution of microbes. Nonetheless, human activities accelerate the pace at which microorganisms develop and spread resistance. AMR is a complex and multidimensional problem, threatening not only human and animal health, but also regional, national, and global security, and the economy. Inappropriate use of antibiotics, and poor infection prevention and control strategies are contributing to the emergence and dissemination of AMR. All healthcare providers play an important role in preventing the occurrence and spread of AMR. The organization of healthcare systems, availability of diagnostic testing and appropriate antibiotics, infection prevention and control practices, along with prescribing practices (such as over-the-counter availability of antibiotics) differs markedly between high-income countries and low and middle-income countries (LMICs). These differences may affect the implementation of antibiotic prescribing practices in these settings. The strategy to reduce the global burden of AMR includes, among other aspects, an in-depth modification of the use of existing and future antibiotics in all aspects of medical practice. The Global Alliance for Infections in Surgery has instituted an interdisciplinary working group including healthcare professionals from different countries with different backgrounds to assess the need for implementing education and increasing awareness about correct antibiotic prescribing practices across the surgical pathways. This article discusses aspects specific to LMICs, where pre-existing factors make surgeons’ compliance with best practices even more important.
