Application prototype for patient education before coronary artery bypass graft surgery

Abstract

Objective: To analyze the content and usability of a mobile application prototype to support patient education in the preoperative period of myocardial revascularization. Methods: This is a quantitative methodological study based on the contextualized instructional design framework. In the analysis stage, a scoping review and a qualitative study were carried out with 13 patients to identify the content to compose the application. In the design and development stage, content was structured. In the implementation stage, resources were configured. In the assessment stage, the Delphi technique was used, with content assessment from the Pasquali criteria and application usability through the ERGOLIST by 20 judges in the first round and 16 in the second. For analysis, the Content Validity Coefficient was used, considered valid above 0.8 and the percentage of agreement equal to or greater than 80%. The binomial test was performed on each item to determine the significance level (p<0.05). Results: Content analysis resulted in a Content Validity Coefficient greater than 0.8 and a percentage of agreement greater than 80% in all analyzed criteria. Usability, on the other hand, presented a percentage greater than 90% in all items. All items analyzed were statistically significant. The OrientaRVM application was composed of 90 screens that form the initial menu and nine sections: understand more about the heart; understand your illness; understand coronary artery bypass graft surgery or breast bypass surgery; care before surgery; care after surgery; rehabilitation and lifestyle changes; patient records; schedule; quiz. Conclusion: OrientaRVM presents reliable content, adequate functionality and was recommended to be used as an auxiliary resource in patient education before myocardial revascularization.
