Development of an educational mobile application for patients submitted to orthognathic surgery.
Cristina Silva Sousa, Ruth Natalia Teresa Turrini
PMID 31340340WHAT IT FOUND
Patients rated an orthognathic surgery education app as easy to use and satisfying.
The study measured usability and satisfaction, not patient outcomes, so it is a teaching aid, not proven care.
Key findings
01Patients rated the app's usability at a mean of 79.8 points, and 22 of 30 scored above the acceptable cutoff of 68.
02User satisfaction averaged 82.9%, and no participant reported being unsatisfied on the satisfaction scale.
03The app's usability and satisfaction scores were not significantly related to age, schooling, or use of the application.

What it does not show
The study measured usability and satisfaction, not clinical outcomes such as recovery, complications, knowledge, or self-care. The 30 participants were recruited by convenience and were mostly from São Paulo, so the ratings may not apply to other patients or regions. The app was available only in Portuguese and only for orthognathic surgery. The text and table give different values for the southeastern region, making the participant description unclear.
Declared interests
The app was registered as a computer program patent at INPI. No funding source or conflict-of-interest declaration is stated in the supplied text.
The easy way to misread this
Do not read the good usability and satisfaction scores as proof that the app improves recovery, knowledge, or self-care. The study evaluated user ratings only and did not compare patient outcomes.
