The World Health Organisation (WHO) recommends routine use of a surgical safety checklist prior to all surgical operations. The aim of this study was to prospectively audit checklist use in orthopaedic patients before and after implementation of an educational programme designed to increase use and correlate this with early complications, mortality and staff perceptions. Data was collected on 480 patients before the educational program and 485 patients after. Pre-training checklist use was 7.9%. The rates of early complications and mortality were 8.5% and 1.9%, respectively. Forty-seven percent thought the checklist improved team communication. Following an educational program, checklist use significantly increased to 96.9% (RR12.2; 95% CI 9.0-16.6). The rate of early complications and mortality was 7.6% (RR 0.89; 95% CI 0.58-1.37) and 1.6% (RR 0.88; 95% CI 0.34-2.26), respectively. Seventy-seven percent thought the checklist improved team communication. Checklist use was not associated with a significant reduction in early complications and mortality in patients undergoing orthopaedic surgery. Education programs can significantly increase accurate use and staff perceptions following implementation.
We conclude that the approach to the medial head of gastrocnemius is free from neurovascular structures and that release of the medial head alone may be efficacious in the operative treatment of isolated gastrocnemius tightness that has failed non-operative treatment.
A best evidence topic was written according to a structured protocol. The question addressed was whether video-assisted mediastinoscopy (VAM) has a better lymph node yield and safety profile than the conventional mediastinoscopy (CM). A total of 194 papers were found, using the reported searches, of which five represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Two studies to date have directly compared CM and VAM with respect to lymph node yield, calculated diagnostics performance and complication rate. In both of these, lymph node yield is shown to be higher using VAM with better sensitivity, negative predictive value and accuracy rates. The favourable figures of lymph node sampling are found to be statistically significant in the single study providing such analysis. Complication rates using VAM are low, however, in the one instance where it is reported as higher than CM, the extensive lymph node dissection used in this technique may be a reasonable explanation for this finding. All studies described here exemplify VAM as a safe and useful tool in mediastinal staging, lymph node dissection and tissue diagnosis of mediastinal diseases given its superior visualization of surrounding structures and advantage of bimanual dissection. The future scope for diagnostic and therapeutic indications of cervical mediastinscopy is anticipated with recent advances and new techniques, such as video-assisted mediastinoscopic lymphadenectomy and virtual mediastinscopy.
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.
