We conducted a case study of the costs of hospitalization in elderly patients with 60 or more years admitted in a reference hospital in the city of Natal, state of Rio Grande do Norte, during the period from January 2005 to December 2009. The Multiple Linear Regression model (log-linear) was applied to analyze the factors associated with hospitalization costs. The results of the regression model showed that each additional day of hospitalization determined a 3% increase in average spending and admissions of elderly who died produced a 71.6% increase in costs relative to admissions of patients dischargedhttps://creativecommons.org/licenses/by/4.0/idososcustos hospitalaresdoenças transmissíveis.agedcommunicable diseaseshospital costsFatores associados ao custo das internações hospitalares por doenças infecciosas em idosos em hospital de referência na cidade do Natal, Rio Grande do NorteAssociated factors with costs of hospital admissions for infectious diseases in the elderly in a hospital in Natal, Rio Grande do Nortearticlehttp://dx.doi.org/10.1590/1414-462x201500010011
