Development and validation of a mobile application prototype for postoperative cardiac surgery.

Area of Science:

• Health Informatics
• Digital Health
• Patient Monitoring

Background:

• Postoperative care for cardiac surgery patients requires effective monitoring strategies.
• Mobile applications offer a potential solution for remote patient management.
• Stimulating self-care is crucial for successful recovery after cardiac procedures.

Purpose of the Study:

• To develop a prototype application for monitoring patients in the postoperative period of cardiac surgery.
• To validate the content, appearance, and semantics of this application prototype.
• To assess the potential of the application in promoting self-care among cardiac surgery patients.

Main Methods:

• A technological development study utilizing Contextualized Instructional Design.
• Content and appearance validation by a committee of 17 health specialists.
• Semantic validation conducted with 10 cardiac surgery outpatients.

Main Results:

• The VivaCor PósOp application prototype comprises 43 screens.
• Content validity ratio (CVR) and appearance validity index (AVI) were high (0.86 and 0.99).
• Total content validity index (CVI) for semantic validation by patients was 0.978.

Conclusions:

• The VivaCor PósOp application prototype demonstrated strong content, appearance, and semantic validity.
• The validated prototype has the potential to encourage self-care in patients recovering from cardiac surgery.
• This digital tool supports enhanced postoperative monitoring and patient engagement.
