Currently submitted to: Journal of Medical Internet Research

Date Submitted: Feb 2, 2020
Open Peer Review Period: Feb 10, 2020 - Mar 10, 2020
(closed for review but you can still tweet)

NOTE: This is an unreviewed Preprint

Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).

Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer-Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.

Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).

Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.

Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.

Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.

Colorectal survivors after discharge face multiple challenges and eHealth may potentially support them through providing tools such as smartphone apps. They have lots of capabilities to exchange information and could be used for remote monitoring of these patients.


In this study, we addressed required features for apps designed to follow-up colorectal cancer patients.


Features of related apps were extracted through the literature; the features were categorized and then they were modified. A questionnaire is designed containing the features listed and prioritized based on MoScoW technique and an open question for each category. The link of the questionnaire is shared among oncological surgeons and related clinical experts in the country. The answers were analyzed using CVR and the minimum feature set of a monitoring app to follow-up colorectal cancer patients were obtained.


The questionnaire contained ten sections evaluating nine categories of features. Eighteen experts filled the questionnaire. the minimum features of the app identified as: patient information registration, sign and symptoms monitoring, education, reminders, and patient evaluation (0.42<CVR<0.85). Features including physical activity, personalized advice, and social network did not get the minimum score (-0.11<CVR<0.39).


The requirements set could be used for designing an app for the targeted population. Further research might address patient’s concerns on such an app also the extensibility of this features to other types of cancer.
