Acute gastroenterocolitis (GECA) in healthy adults is a frequent cause of looking for medical care in emergency care units and most cases are aimed at etiology viral infection or food toxin, being generally self-limited with good prognosis and only need for treatment with behavioral measures and use of medications for relief symptomatic. Anamnesis is the main resource for the diagnosis and stratification of GECA severity and is infrequent alterations of physical examination and complementary examinations without association with symptoms of alert. Telemedicine has become a resource that allows easier and faster access to medical evaluation, with low cost and rational use of resources. Virtual emergency care is part of Hospital Israelita Albert Einstein (HIAE) institutional routine and there is a large number of consultations whose final diagnosis was GECA. It is not known whether the accuracy of diagnosis of GECA by telemedicine is not inferior to the diagnosis by face-to-face evaluation, considered the Golden pattern. The aim of the study is compare the diagnostic accuracy of GECA by telemedicine with that of face-to-face care. It is a prospective randomized study with a population of adult patients who sought in person the screening of the Morumbi Emergency Care Unit of HIAE with symptoms suggestive of GECA (diarrhea with or without other symptoms of the digestive tract and infectious). Patients whose screening will be excluded of nursing directed for immediate evaluation in the emergency room and patients with dysfunctions organisms or immunosuppression. Patients who accept and sign the informed consent form will be randomized into 2 groups: A) immediate face-to-face evaluation; B) evaluation initially by telemedicine and sequentially at face-to-face evaluation. In both cases, the ICD diagnostics will be compiled and grouped according to clinical significance and will be the primary outcome of the study. Service time, exams requested, guidelines, prescription and destination will also be analyzed. Patients and doctors who undergoing group B assessment will be blinded to the telemedicine assessment data.

The face-to-face assessment will be carried out by the local UPA medical and assistance team and the assessment by telemedicine by the fixed medical team of the HIAE service responsible for urgency / emergency. Both in face-to-face evaluation, as well as telemedicine, clinical data, final diagnosis, destination, total time of care, guidance and prescription will be computed. In the face-to-face evaluation, complementary exams and medications received in situ were computed. Final diagnoses will receive nomenclature according to the International Statistical Classification of Diseases and Problems Health-Related - ICD 10 (institutional medical record requirement - Cerner) and will be grouped according to equivalence of syndromic diagnosis. The diagnosis of the face-to-face assessment is made according to protocols based on extensive medical literature and approved by the institutional clinical staff, being representative of current medical practice and will be considered the gold standard diagnosis. Patients evaluated by telemedicine will be blinded to the diagnosis, recommended destination, guidelines and prescription performed by the medical team. UPA doctors will be blind to the doctor's assessment telemedicine and telemedicine doctors will not have access to the data obtained in the screening.
