Brief summary

Pilot study to evaluate the effect of prehabilitation programme through a mobile application PREHapp in colon cancer surgery. The objectives of this pilot study were to evaluate the usability of the PREHapp for people undergoing colon cancer surgery, estimate the effect of the app on functional recovery after surgery and to evaluate complications during the postoperative period after 4 weeks of follow-up.

Design outcomes

Primary

Measure	Time frame	Description
Usability	2 year	Evaluate the usability of PREHapp with the System Usability Scale (SUS). The SUS is a reliable and valid 10-statement usability scale suitable to assess a wide range of eHealth technologies. The total SUS score ranges from 0 to 100, and higher scores reflect higher usability. An SUS score of at least 62.7 was considered acceptable, and 68 or above was regarded as above average in terms of usability quality

Secondary

Measure	Time frame	Description
Functional recovery	2 year	Estimate the effect of the prehabilitation with app on functional recovery measured with the 6-minute walk test.
Complications	2 year	Evaluate complications during the postoperative period after 4 weeks of follow-up: clavien-dindo classification
