AimThe aim of this scoping review was to provide an overview of the literature about the process of obtaining consent from adult patients undergoing planned surgery from the healthcare professionals' perspective and analyse knowledge gaps.BackgroundThe process of obtaining consent for planned elective surgery manifests an individual's fundamental right to decide what happens to their body. The process is often suboptimal and problematic, placing a significant resource burden on health systems globally. Deficiencies in the documentation on consent forms have also been shown to increase the risk of operating room error.DesignScoping review.MethodsArksey and O′Malley's (International Journal of Social Research Methodology, 8, 2005 and 19) five‐step scoping review methodology was used.ResultsFifty‐three articles were included; 39 primary and 14 secondary research publications. Three key findings were identified; there is currently low‐level evidence about surgical consent processes to inform clinical practice; junior doctors obtain surgical consent frequently, yet this process was likely undertaken sub‐optimally; and current knowledge gaps include capacity assessment, decision‐making and pre‐procedural consent checks.ConclusionPlanned surgical consent processes are complex, and both surgeons and perioperative nurses are essential during the process. While surgeons have responsibility to obtain consent, perioperative nurses provide a safety net in the surgical consent process checking the surgical consent information is correct and has been understood by the patient. Such actions may influence consent validity and patient safety in the operating room. Knowledge gaps about capacity assessment, decision‐making, pre‐procedural checks and the impact of junior doctors obtaining consent on patient understanding, safety and legal claims are evident.Relevance to clinical practiceThis review highlights the importance of the surgical nurse's role in the planned surgical consent process. While the responsibility for obtaining surgical consent lies with the surgeon, the nurse's role verifying consent information is crucial as they act as a safety net and can reduce error in the operating room.No patient or public contributionThe authors declare that no patient or public contribution was made to this review in accordance with the aim to map existing literature from the healthcare professionals' perspective.
