QR Codes 2022 - Poor hospital care in Peru is responsible for the constant dissatisfaction and time delays in care in a large number of patients who go to public hospitals. In this work, the development of a system was carried out to optimize the process of medical consultations using QR codes in the Hospitals of Peru that would allow the reduction of time in care and the increase in patient satisfaction. The implementation of the proposed system was supported by a new medical care process diagram, as well as the development of a mobile application for scheduling and managing appointments, complemented by the use of QR codes to display information. The validation process was carried out among a selected group of patients, determining that the time spent in medical attention decreased compared to that of a current medical appointment, in the same sense, satisfaction was increased.
