App for anesthetists engaged in pre-operative evaluations of adult patients. Based on the most recent international guidelines, it integrates commonly collected anamnestic data to provide timely and systematic scores and useful advice for perioperative management. The app guides the anesthetist in collecting a complete and timely medical history, avoiding forgetting key assessments. Furthermore, by entering useful data for multiple scores only once, you will avoid having to re-enter the same values ​​multiple times. The app can also be extended and optimized for the pediatric population and ultra-specialist surgeries. The app has a mere consultative value and has no medico-legal value.
