20.500.12556/RUL-22465 A comparison of analytic models for the costs of the hospitalized diabetic patients OBJECTIVE: To compare some survival models as applied to the estimation of thecosts of hospitalization as a function of several covariates in diabetic patients. The application of the Aalen regression model (Aalen, 1989) to medical costs is stressed. DESIGN: Retrospective observational study analyzinghospitalizations in a cohort of diabetic patients with a follow up of4.5 years. STUDY POPULATION: A total of 2550 patients have been included in the cohort, according to clinical-based enrollment standards. The patients with at least one hospitalization have been considered in this analysis. METHODS: Costs have been modelled using five different regression model: the ordinary least square regression model, the logistic regression model using the median and the third quartile of the costs distribution as cut-off points,the parametric survival model assuming Weibull distribution, the Cox proportional hazard model and the Aalen additive regression model. CONCLUSIONS: The Aalen additive regression model applied to the costs has the best performances in estimating the mean hospitalization costs for specific clinical profiles. true false false Angleški jezik Neznan jezik Delo ni kategorizirano 2014-07-11 14:26:45 2014-07-11 14:26:45 2022-06-02 03:50:35 0000-00-00 00:00:00 2005 0 0 Str. 135-145 no. 1 Vol. 2 2005 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 311 1854-0023 24325213 http://mrvar.fdv.uni-lj.si/pub/mz/mz2.1/zigon.pdf 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=22465 Fakulteta za družbene vede Metodološki zvezki 0 0 0
