Objective: Long waiting times for elective surgery reflect not just backlog issues but systemic inefficiencies that disrupt the smooth flow of patients through the surgical care pathway. This systematic review adopts a holistic approach to summarize global policies, strategies, and interventions aimed at reducing elective surgery wait times.
Method: A comprehensive electronic search was performed in PubMed, EMBASE, SCOPUS, Web of Science, and Cochrane Library from December 2019 to January 2020 and updated in April 2022. Eligible studies, published after 2013, focused on waiting lists for major elective surgeries in adults, excluding cancer-related surgeries. Both randomized and non-randomized studies and systematic reviews were included. Study quality was assessed using ROBINS-I, AMSTAR 2, and CASP tools, as appropriate. The review was registered in PROSPERO (CRD42019158455) and reported using a PRISMA flow diagram.
Results: From 7543 records, 92 articles met the inclusion criteria. Evidence was categorized into seven strategic areas: referral management, patient prioritization, preventing scheduled surgery cancellations, perioperative time management, quality improvement methods for surgical care pathways, and waiting time targets for hospitals. Strategies such as referral management, patient prioritization, and preventing cancellations had the most significant impact on reducing waiting times, while perioperative time management and waiting time targets proved less effective.
Conclusion: The review highlights that targeted interventions at different stages of the surgical care pathway yield variable impacts on overall waiting times. While individual measures had limited effects, combining multiple short-term strategies may be more beneficial, particularly for health systems recovering from the COVID-19 pandemic.
