Several studies from Anglo-American countries indicate that in non-psychiatric hospital departments mentally ill patients have a longer length of hospital stay than mentally well, while in Austria and Germany, until now, no studies concerning this question exist. Therefore, we investigated the influence of psychiatric comorbidity on the length of stay in 608 patients of medical, surgical and gynecological departments in Vienna and Tyrol. Based on the Clinical Interview Schedule, 28.1% of the patients in this sample suffered from psychiatric disorders. The presence of psychiatric disorders, as well as type of hospital department (medical department), higher age, more previous non-psychiatric treatment periods, and more somatic diagnoses predicted a longer duration of inpatient treatment. To avoid the influence of cofounding variables, psychiatric cases were matched with psychiatric non-cases. The mentally ill group was treated for a markedly longer period as inpatients than the mentally well. Patients with a diagnosis of dementia or of substance abuse showed a significantly increased length of stay, while we could not confirm this for other psychiatric diagnoses.
来自英美的多项研究表明，在非精神科医院科室中，精神疾病患者的住院时间比精神正常者更长，而在奥地利和德国，到目前为止，尚无关于此问题的研究。因此，我们调查了精神疾病合并症对维也纳和蒂罗尔州内科、外科和妇科608例患者住院时间的影响。根据临床访谈表，该样本中28.1%的患者患有精神疾病。精神疾病的存在、医院科室类型（内科）、年龄较大、既往非精神科治疗次数较多以及躯体诊断较多均预示着住院治疗时间较长。为避免混杂变量的影响，将精神疾病患者与非精神疾病患者进行匹配。精神疾病组的住院治疗时间明显长于精神正常组。诊断为痴呆或药物滥用的患者住院时间显著延长，而其他精神疾病诊断则未得到证实。
