[Representation of Internal Medicine in G-DRG System - Analysis of Reasons for Prolonged Length of Stay].

Background There is an ongoing discussion within the German Society of Internal Medicine (DGIM) and the Professional Association of German Internists (BDI) about the appropriate depiction and remuneration of internal medicine in the G-DRG. Method Therefore, cases with a significantly prolonged length of stay were analyzed in a multicenter study. 124 cases from 6 hospitals were collected for evaluation. Results The results show that the observed prolongation of hospitalization was mainly due to medical reasons. Discussion Thus, patients with unclear symptoms and consequently need for a thorough workup could not be identified to cause longer inpatient stay. Instead, treatment complications and comorbidities led to extended hospitalization. The results also reveal prolonged hospitalization as a consequence of unsettled or delayed postdischarge care e. g. in rehabilitation facilities.
