Role of intraoperative processes of care during major upper gastrointestinal oncological resection in postoperative outcomes: a scoping review protocol.

ABSTRACT

INTRODUCTION: Optimal delivery and organisation of care is critical for surgical outcomes and healthcare systems efficiency. Anaesthesia volumes have been recently associated with improved postoperative recovery outcomes; however, the mechanism is unclear. Understanding the individual processes of care (interventions received by the patient) is important to design effective systems that leverage the volume-outcome association to improve patient care. The primary objective of this scoping review is to systematically map the evidence regarding intraoperative processes of care for upper gastrointestinal cancer surgery. We aim to synthesise the quantity, type, and scope of studies on intraoperative processes of care in adults who undergo major upper gastrointestinal cancer surgeries (oesophagectomy, hepatectomy, pancreaticoduodenectomy, and gastrectomy) to better understand the volume-outcome relationship for anaesthesiology care. METHODS AND ANALYSIS: This scoping review will follow the Arksey and O'Malley framework and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension framework for scoping reviews. We will systematically search MEDLINE, Embase and Cochrane databases for original research articles published after 2010 examining postoperative outcomes in adult patients undergoing either oesophagectomy, hepatectomy, pancreaticoduodenectomy, or gastrectomy, which report at least one intraoperative processes of care (intervention or framework) applied by anaesthesia or surgery. The data from included studies will be extracted, charted, and summarised both quantitatively and qualitatively through descriptive statistics and narrative synthesis. ETHICS AND DISSEMINATION No ethics approval is required for this scoping review. Results will be disseminated through publication targeted at relevant stakeholders in anaesthesiology and cancer surgery.
