The change of hospital internal medicine: a study on patients admitted in internal medicine wards of 8 hospitals of the Lazio area, Italy

The hospital internal medicine (IM) needs to adapt to the socio-demographic changes occurred during the last thirty years: patients currently show an increased overall complexity owing to the increase in the average age of the patients admitted, to more several and severe comorbidities, and a higher concentration in our wards of most severe cases. Our departments have to change in order to pursue a more efficient organization and to offer care to users modulated according to their needs and conditions. The Intensity of Care in Internal Medicine Group of the Federation of Associations of Hospital Doctors on Internal Medicine - Lazio carried out a population-based study in eight Internal Medicine wards of the region with the aim of characterizing the patients there admitted, using the modified early warning score (mEWS), monitoring and evaluating the outcomes of hospitalization. This has allowed us to determine the cut-off of the score indicating a greater statistical probability of a fatal outcome corresponding to 3, contrary to what originally reported by Subbe <em>et al.</em> in 2001. According to our results into the Departments of IM should be provided an area of high care, where monitor and stabilize the patients admitted with a mEWS score ≥3, before transferring them to the wards of lower intensity of care. This organizational model of the high care of medical patients has the benefit of offer the technical and professional assistance appropriate to the level of clinical risk, with more intensive care to more critical stages of illness.
