[A map for the improvement of healthcare: Swiss Health Care Atlas].

The Swiss Health Care Atlas (ASSS) is a free platform accessible to healthcare professionals and the general public. It provides a detailed overview of healthcare practices and the use of pharmaceutical and technological resources in both acute and outpatient care settings throughout Switzerland. It serves as an interactive tool for visualizing medical services and practices in Switzerland, along with regional variations. The ASSS allows the identification of potential under and overutilization of healthcare services, making it a valuable planning and management tool for healthcare and political authorities. This article reviews healthcare practices related to general internal medicine and guides the reader in interpreting a selection of ASSS indicators.
