Anesthesia-related activities produce 25% of all operating room (OR) waste and contribute to environmental pollution and climate change. The aim of this study was to document Canadian anesthesiologists' current practice, attitudes towards, and perceived barriers regarding recycling of OR waste and environmental sustainability efforts. ⋯ Canadian anesthesiologists appear ready to incorporate environmental sustainability in their practice but indicate that significant barriers exist. Our study highlights the need for further educational programs and implementation strategies.

Statistical approaches have been developed to detect bias in individual trials, but guidance on how to detect systematic differences at a meta-analytical level is lacking. In this paper, we elucidate whether author bias can be detected in a cohort of randomized trials included in a meta-analysis. ⋯ When combining trial-level data to produce a pooled effect estimate, investigators must consider sources of potential bias. Our results suggest that systematic errors can be detected using meta-regression, although further research is needed to examine the sensitivity of this model. Systematic reviewers will benefit from the availability of methods to guard against the dissemination of results with the potential to mislead decision-making.
