Abstract 4034


Chemotherapy-induced nausea and vomiting (CINV) continue to be a clinical problem, particularly in the delayed phase. Great variability between perception of healthcare professionals and patients, regarding incidence & severity of CINV1-9. CINV lack of control worsens the quality of life of patients and it is associated with complications12-13 increasing costs for healthcare services14.CINV app is a free service addressed to patients treated with emetogenic chemotherapy (CT), empowering patients to report CINV impact in life and relevant information. This study aims to evaluate the usability and acceptability of a smartphone app to improve CINV management in patients receiving CT, by cancer nursing.


We used 4-dimensions test (content, graphic design, navigation and clinical utility) to evaluate APP's usability and acceptability. Clinical and technical researchers worked together to develop the app’s test. 8 National Hospitals with specialized oncology nursing services were included. 45 cancer nurses invited to participate (from 9 to 23 April 2018) and 33 filled in the test, after making a clinical case simulation through the app.

App was easy to use and had relevant content, although improvement is possible. 91% nurses agree that more than 50% of their patients will be able to use the APP and 88% believe that report generated will be useful in practice.


The CINV app addresses main concerns for patients receiving chemotherapy, clinical situation and individual emetic risk of patient or complexity of the prescribed antiemetic regimen and impact of CINV in their daily life. Soliciting feedback from oncology nurses, we ensured that the app was acceptable and beneficial for patients and clinicians. Some points to improve the app in future. Reporting of symptoms after CT enhances CINV management, self-care, and participation without being a burden to patients, indicating that app can be used in clinical practice by patients.
