In the course of a year the prevalence of psychiatric comorbidity as well as the effect of psychiatric comorbidity on the length of stay on two internal medical wards we investigated. When examined by separate methods, the prevalence of psychiatric comorbidity reached 36 % (ICD-10 diagnosis) in a sample of 511 medical inpatients of a university hospital. The study shows that patients with psychiatric comorbidity have a significantly longer length of stay - up to 8.2 days compared with inpatients with mere internal diagnosis. This association was not influenced by the length and the severity of the illness. The findings lead to the conclusion that psychiatric comorbidity is a central contributor to one of the most important factors of medical costs - the length of stay.
在一年的时间里，我们对两家内科病房中精神疾病共病的患病率以及精神疾病共病对住院时间的影响进行了调查。当采用不同方法进行检查时，在一所大学医院的511名内科住院患者样本中，精神疾病共病的患病率达到了36%（国际疾病分类第十版诊断标准）。研究表明，患有精神疾病共病的患者住院时间明显更长——与仅患有内科疾病的住院患者相比，多出8.2天。这种关联不受疾病时长和严重程度的影响。这些发现得出的结论是，精神疾病共病是医疗费用最重要因素之一——住院时间的一个核心促成因素。
