We read with interest the study of Siontis and colleagues,1 which reported that, during 2009, among 118 different clinical prediction rules (CPRs) designed to estimate the risk of all-cause mortality, only 10 were studied in 4 or more separate groups of patients, and of these, only 1 CPR was reasonably accurate across all studies.1 Among the 118 CPRs selected for this study, there was also the Multidimensional Prognostic Index (MPI), derived from a standardized Comprehensive Geriatric Assessment, and developed and validated in 2 independent cohorts of older patients hospitalized for acute disease or relapse of a chronic disease, with a close agreement between the estimated and the observed mortality after both 6 months and 1 year of follow-up.
