Purpose Digital tools such as mobile apps and wearable devices have potential to improve preoperative preparation and facilitate ‘prehabilitation’ for abdominal surgery patients. This scoping review summarised digital tools used preoperatively by abdominal surgery patients for both monitoring, and for prehabilitaiton. Methodology Databases were searched from inception to 1 May 2023. Studies investigating the use of a wearable sensor device, mobile app or digital sensor in adult patients during the preoperative period leading up to any abdominal surgery were included. All included studies had to involve digital tools used by patients. Results A total of 32 studies were included. Tools investigated were predominately consumer grade wearables, that were often used in companion with a mobile device. Most studies focused on the feasibility of devices and mobile applications to measure aspects of perioperative health such as mobilisation, with very limited evidence on the effect of these tools on surgical outcomes. Dedicated tools to deliver prehabilitation programs or monitor patient preoperative physiology were also minimal. Patient reported evaluation of digital tools were mostly positive, however scarcely reported. Conclusion The use of digital technologies to prepare patients for surgery preoperatively is promising but current evidence is sparse. Further research is required to clinically validate digital tools within the preoperative space, and also on the implementation of digital tools within structured prehabiliation packages.
