Efficiency of the "Medidux" Smartphone App for Demission Management in Patients Medicated in Acute Admission Unit (AAU)

The goal of this clinical trial is to evaluate whether the use of the medidux™ smartphone app can optimize post-discharge management for patients admitted to Acute Admission Units (AAU) with non-urgent health complaints. This trial includes adult patients (age ≥ 18) in Emergency Severity Index (ESI) triage system groups 4 (standard) or 5 (non-urgent), presenting with primary symptoms such as cough, back pain, or abdominal discomfort. The main question it aims to answer is: Can the medidux™ app reduce the incidence of AAU readmissions, emergency hospitalizations, or consultations with other medical providers within 7 days after initial admission? Researchers will compare participants using the medidux™ app (intervention arm) with those receiving standard care (control arm) to observe potential differences in the rates of readmissions, emergency hospitalizations, and medical consultations. Participants will: * use the medidux™ app to monitor their symptoms and vital parameters for 7 days after discharge (intervention arm). * receive follow-up consultations at day 7 and at day 28 to assess symptom progression and any healthcare interactions (both arms).
