Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global priority not fully understood. We quantified burden SSI after gastrointestinal surgery in countries all parts world.
Background80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative breast, colorectal, gastric surgery hospitals worldwide, focusing the effect disease stage complications mortality.MethodsThis was multicentre, international prospective cohort study consecutive adult patients undergoing for primary or requiring skin incision done under general neuraxial...

Transpl Infect Dis 2011. All rights reserved Aim. review the clinical presentation, diagnosis, treatment outcomes 30 transplant recipients (SOTRs) with or from 3 Midwestern academic medical centers. Background. The endemic fungal pathogens, Histoplasma capsulatum Blastomyces dermatitidis , may cause severe...
PURPOSE To provide resource-stratified, evidence-based recommendations on the early detection of colorectal cancer in four tiers to clinicians, patients, and caregivers. METHODS American Society Clinical Oncology convened a multidisciplinary, multinational panel medical oncology, surgical surgery, gastroenterology, health technology assessment, epidemiology, pathology, radiology, radiation patient advocacy experts. The Expert Panel reviewed existing guidelines conducted modified ADAPTE...
The 2015 Lancet Commission on global surgery identified and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility planned surgical services around world, which have also been neglected in pandemic recovery planning. This study aimed to develop validate a novel index support local elective system strengthening address growing backlogs.
The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery not been assessed on a global scale. aim of this study was to evaluate reported checklist use settings and examine the relationship with perioperative mortality patients who had laparotomy.In two multinational cohort studies, adults undergoing laparotomy were compared those having elective gastrointestinal surgery. Relationships between determined using...
Abstract Background The National Institute for Health Research Global Unit on Surgery is establishing research Hubs in low- and middle-income countries (LMICs). aim of this study was the to prioritize future into areas unmet clinical need patients LMICs requiring surgery. Methods A modified Delphi process overseen by Hub leads engaged LMIC clinicians, expert methodologists. four-stage iterative delivered topics. This included anonymous electronic voting, teleconference discussions a 2-day...
Rwanda is a densely populated low-income country in East Africa. Previously considered failed state after the genocide against Tutsi 1994, has seen remarkable growth over past 2 decades. Health care predominantly delivered through public hospitals and emerging private sector. More than 80% of patients are covered by community-based health insurance (Mutuelle de Santé). The cancer unit at Biomedical Center (a branch Ministry Health) responsible for setting implementing policy. made progress...
In April 2015, we initiated a training program to facilitate earlier diagnosis of breast cancer among women with symptoms in rural Rwanda. The goal this study was assess the impact intervention detection on knowledge and skills health center nurses community workers (CHWs).We assessed nurses' CHWs' about risk factors, signs symptoms, treatability through written test administered immediately before, after, 3 months after trainings. We clinical examination before trainings then during ongoing...
Access to surgical care in low- and middle-income countries (LMICs) remains deficient without an adequate workforce. There is limited understanding of the gender gap trainees LMICs. In Rwanda, females fill only one 20 positions available. Understanding surgeons' experiences perceptions careers may help facilitate support for contribute global We performed qualitative analysis on through semi-structured interviews all female surgeons (n = 6) corresponding male who are training or have trained...
BackgroundEnd colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation end after left-sided resection.
There is a strong need for expanding surgical workforce in low- and middle-income countries. However, the number of medical students selecting careers not sufficient to meet this need. In Rwanda, there an additional gender gap speciality selection. Our study aims understand early variables involved junior students' preference specialisation with focus on disparities.We performed cross-sectional survey during their clinical rotation years at University Rwanda. Demographics, preference,...
Abstract Background Identification of patients at high risk surgical-site infections may allow surgeons to minimize associated morbidity. However, there are significant concerns regarding the methodological quality and transportability models previously developed. The aim this study was develop a novel score predict 30-day infection after gastrointestinal surgery across global context externally validate against existing models. Methods This secondary analysis two prospective international...
The WHO framework for early cancer diagnosis highlights the need to improve health care capacity among primary providers. In Rwanda, general practitioners (GPs) at district hospitals (DHs) play key roles in diagnosing, initiating management, and referring suspected patients with cancer. We sought ascertain educational resource needs of GPs provide a blueprint that can inform future capacity-building efforts.We administered cross-sectional survey study practicing 42 Rwandan DHs assess gaps...
