Hospitalisation costs of cystic fibrosis.

Objective: To calculate per-case hospital costs for patients with cystic fibrosis under routine conditions from a healthcare provider's perspective; identify the impact of different cost categories; investigate whether cases with cystic fibrosis can be grouped into homogenous cost groups according to defined severity levels; and determine the value of specific factors as predictors of hospital cost variations.

Methods: All data were collected from cases (n = 131) admitted to an inpatient cystic fibrosis unit under routine conditions during a period of 6 months in 2004. All costs were calculated for the year 2004 and divided into categories with high and low impact on variation in hospitalisation costs between patients.
