IntroductionThe Lancet Commission on Global Surgery proposed the perioperative mortality rate (POMR) as one of the six key indicators of the strength of a country’s surgical system. Despite its widespread use in high-income settings, few studies have described procedure-specific POMR across low-income and middle-income countries (LMICs). We aimed to estimate POMR across a wide range of surgical procedures in LMICs. We also describe how POMR is defined and reported in the LMIC literature to provide recommendations for future monitoring in resource-constrained settings.MethodsWe did a systematic review of studies from LMICs published from 2009 to 2014 reporting POMR for any surgical procedure. We extracted select variables in duplicate from each included study and pooled estimates of POMR by type of procedure using random-effects meta-analysis of proportions and the Freeman-Tukey double arcsine transformation to stabilise variances.ResultsWe included 985 studies conducted across 83 LMICs, covering 191 types of surgical procedures performed on 1 020 869 patients. Pooled POMR ranged from less than 0.1% for appendectomy, cholecystectomy and caesarean delivery to 20%–27% for typhoid intestinal perforation, intracranial haemorrhage and operative head injury. We found no consistent associations between procedure-specific POMR and Human Development Index (HDI) or income-group apart from emergency peripartum hysterectomy POMR, which appeared higher in low-income countries. Inpatient mortality was the most commonly used definition, though only 46.2% of studies explicitly defined the time frame during which deaths accrued.ConclusionsEfforts to improve access to surgical care in LMICs should be accompanied by investment in improving the quality and safety of care. To improve the usefulness of POMR as a safety benchmark, standard reporting items should be included with any POMR estimate. Choosing a basket of procedures for which POMR is tracked may offer institutions and countries the standardisation required to meaningfully compare surgical outcomes across contexts and improve population health outcomes.
A bulky guanidinate ligand has been utilized in supporting a dichloroarsine, which is an excellent precursor to an arsenium cation and a 2,2'-bipyridine base stabilised arsetidinium dication.
Introduction Trauma resuscitation at dedicated trauma centers typically consist of ad-hoc teams performing critical tasks in a time-limited manner. This creates a high stakes environment apt or avoidable errors. Reporting of errors in trauma resuscitation is generally center-dependent and lacks common terminology. Methods We conducted a systematic review by searching Ovid Medline, Scopus and Embase from inception to February 24, 2021 for errors in adult trauma resuscitation. English studies published after 2001 were included. Studies were assessed by two independent reviewers for meeting inclusion/exclusion criteria. Errors were characterized from the included studies and a summary table was developed. Our review was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42020152875).
ResultsThe literature search retrieved 4658 articles with 26 meeting eligibility criteria. Errors were identified by morbidity and mortality rounds or other committee in 62%, missed injuries on tertiary assessment or radiology review in 12%, deviations from algorithmic guidelines in 12% or predefined for chest tube complications, critical incident reporting, aspiration or delays in care. In total there were 39 unique error types identified and divided into 9 categories including Emergency Medical Services handover, airway, assessment of injuries, patient monitoring and access, transfusion/blood related, management of injuries, team communication/dynamics, procedure error and disposition. Conclusions Overall, our systematic review identified 39 unique error types in trauma resuscitation. Identifying these errors is imperative in developing systems for improvement of trauma care.
Objectives Trauma resuscitations are sporadic, high-acuity situations and conducting observation in the trauma bay for the purpose of quality improvement is challenging. We aim to review contemporary uses of trauma video review. Methods Medline and Embase were searched from 1980 to May 2020 for studies involving trauma video review. English studies of adult and paediatric populations were included for study and analysed for uses of trauma video review, outcomes measured and any resulting quality improvement (QI) initiatives. Results A total of 463 publications were identified with 21 studies meeting eligibility for final inclusion. A majority of studies (11) observed technical skills with analysis of critical procedures, including tracheal intubation and thoracotomy. The remaining studies observed team dynamics and communication. Overall, eight studies resulted in new policies being put in place for trauma resuscitations and six studies utilized trauma video review as an educational tool. Conclusions This study highlights common uses of trauma video review. The greatest benefit for this new technology is in quality improvement and education. The majority of studies focussed on critical procedures and QI initiatives, such as checklists, protocols and continued education. We recommend adoption of video review systems for ongoing improvement of team dynamics and overall trauma and emergency resuscitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
