Comparison between PROFUND and PALIAR indexes in polypathological patients with advanced non-oncologic chronic diseases

Abstract Background and objective To compare the discrimination power of PROFUND and PALIAR indexes for predicting mortality in polypathological patients with advanced non-oncologic chronic disease. Material and methods Prospective multicentre cohort study. We included polypathological patients with advanced non-oncologic chronic disease, who were admitted to internal medicine departments between July 1st and December 31st, 2014. Data was collected from each patient on age, sex, categories of polypathology, advanced disease, comorbidity, functional and cognitive assessment, terminal illness symptoms, need for caregiver, hospitalisation in the past three and 12 months and number of drugs. We calculated the PROFUND and PALIAR indexes and conducted a 12-month follow-up. We assessed mortality with the Kaplan–Meier survival curves and the discrimination of indexes with the ROC curves. Results We included 213 patients with a mean (standard deviation) age of 83.0 (7.0) years, 106 (49.8%) of whom were female. Mortality at six months was 40.4% and at 12 months 50.2%. Deceased patients scored higher scores on the PROFUND [11.2(4.2) vs 8.5(3.9); p C I 0.665–0.803) was higher than of PROFUND, and there was no difference at 12 months. Conclusions In polypathological patients with advanced non-oncologic chronic disease, the PALIAR index had better discrimination power than PROFUND index at 66 months and there were no differences at 12 months.
