In German inpatient psychosomatics per diem lump sums will be introduced as reimbursement rates by 2013. It was the aim to calculate total inpatient costs per case for the psychosomatic treatment of patients with anorexia nervosa and to identify cost predictors.
The sample comprised of 127 inpatients. Cost calculation was executed from the hospital's perspective, mainly using microcosting. Medical records provided data on patient characteristics and individual resource use. Two generalized linear models with gamma distribution and log link function were estimated to determine cost predictors by means of demographic data, comorbidities, and body-mass-index at admission.
Inpatient costs amounted to 4,647 €/6,831 US$ per case (standard deviation 3,714 €/5,460 US$).The admission BMI and "Disorders of Adult Personality and Behavior" were significant cost predictors (p < 0.05).
The formation of patient groups within the diagnosis anorexia nervosa should be oriented towards the determined cost predictors.
2013 年起，德国将采用住院心身医学每日费用总额作为报销标准。本研究旨在计算神经性厌食症患者心身治疗的每位患者的住院总费用，并确定费用预测因子。
该研究纳入了 127 例住院患者。从医院角度进行成本计算，主要采用微观成本法。病历资料提供了患者特征和个体资源使用情况的数据。采用具有伽马分布和对数链接函数的 2 个广义线性模型，根据人口统计学数据、合并症和入院时的体重指数（BMI）来确定费用预测因子。
每位患者的住院费用为 4647 欧元/6831 美元（标准差为 3714 欧元/5460 美元）。入院 BMI 和“成人人格和行为障碍”是显著的费用预测因子（p < 0.05）。
在神经性厌食症的诊断中，应根据确定的费用预测因子来分组患者。
