title: [Comorbidity, pluripathology, resource use and prognosis of patients hospitalized in internal medicine areas].
abstract: OBJECTIVE
  To compare the concept of patient with pluripathology (PP) with the index of comorbidity of Charlson (IC) respect to the resources use and prognosis of hospitalized patients.
  
  
  METHODS
  An observational prospective study of 207 consecutively hospitalized patients in an internal medicine unit was conducted. The PP, a variant of PP with three or more criteria (PP3), IC and IC fit to the age (ICE) were determined, and their relation with the consumption of resources (emergency attentions, programmed consultations of specialties and episodes of hospitalization in the last year, length of stay, own procedures, other specialty procedures and consulting) and prognosis (hospital mortality, significant functional deterioration and rehospitalization) were stayed.
  
  
  RESULTS
  The frequency of PP and PP3 was 40.6 and 16.9%, respectively. The median of the IC and ICE score were 2 (0-7) and 4 (0-11), respectively. We found the following independent relations: IC of 3 or greater with the rehospitalization and the length of stay; ICE of 5 or greater with mortality; PP3 with mortality, rehospitalization and emergency visits, hospitalizations and consultations in the last year; the categories B and F of PP with hospitalizations in the last year; the category D of PP with consultations in the last year; and the association of categories A, B and C with mortality and hospitalizations in the last year. PP was not related in an independent form with any variable.
  
  
  CONCLUSIONS
  The IC and the concept of PP do not identify the same hospitalized patient population. Modifications of the PP definition, like PP3, or the analysis of the different clinical categories of PP and their associations, could improve the utility of this concept.
