Objective: evaluate the effectiveness and usability of a mobile application for post-discharge surveillance of surgical site infection as a support system for clinical decision.
Introduction: Infection of the surgical site (SSI) is one of the main infections related to health care, culminating in financial losses to the health system and high morbidity and mortality, which due to increasingly shorter hospital stays, from 13 to 75% is manifested at home of the patient, requiring health professionals to act more effectively in post-discharge surveillance of this condition. Therefore, considering this problem and the constant evolution of technological resources, with the increase in access and use of smartphones by the population, it is pertinent to develop a mobile application for post-discharge surveillance of surgical site infection. Objective: evaluate the effectiveness and usability of a mobile application for post-discharge surveillance of surgical site infection as a support system for clinical decision. Method: Randomized Clinical Trial to assess effectiveness of a mobile application for post-discharge surveillance of infection of the surgical site. The study will be developed in a large hospital in the city of São Paulo and the study participants will be surgical patients. Expected results: The mobile application for post-discharge surveillance is expected to collaborate in the early detection of potential cases of surgical site infection, to be able to improve post-discharge surveillance strategies, assist in data management, decision making and actions to prevent infection of the surgical site.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| VigiApp | Experimental | the intervention group, which will use the mobile application to detect SSI. The Vigi-App application will be installed on the Smartphone of the selected patients, who will receive training on how to use the application; should access it on days seven, 14, 21 and 30 after the surgical procedure, they will additionally be evaluated in person in an outpatient consultation, according to the hospital routine. The patients in the intervention group will receive notices the day before, through reminders issued by the application, reminding them that they must access and complete the requested information. If the patient presents signs and symptoms of infection on dates other than filling out the application, he can access the application and send his data normally as an extra access. |
|
| telephone call | Sham Comparator | the called control, consisting of the standard infection surgical site post-discharge surveillance the developed infection of the surgical site procedure, by means of a telephone call. You will receive guidance on phone calls; will follow the standard SSI post-discharge surveillance procedure, by means of a telephone call on days seven, 14, 21 and 30 after the date of surgery, being asked about the presence of signs and symptoms of infection according to the instrument previously validated in previous investigation and will be evaluated in person in an outpatient consultation, according to the hospital routine. |
