The authors critically reviewed 26 international and American outcome studies that assessed the effect of psychiatric comorbidity on length of stay for medical/surgical inpatients. Three generations of American studies were defined according to the rigorousness of the methodology. Eighty-nine percent of all studies with sample sizes greater than 110 and 75% of the prospective, rigorously controlled, American studies found a significant association between psychiatric comorbidity and increased length of stay. The findings lead to the conclusion that impaired cognition associated with delirium and dementia, depressed mood, and other personality variables contributes to prolonged hospital stays and greater utilization of hospitals and other health resources after discharge. Recommendations for future research are suggested.
作者对26项国际和美国的结果研究进行了批判性回顾，这些研究评估了精神疾病共病对内科/外科住院患者住院时间的影响。根据方法的严谨性对三代美国研究进行了定义。所有样本量大于110的研究中有89%，以及前瞻性、严格对照的美国研究中有75%发现，精神疾病共病与住院时间延长之间存在显著关联。这些发现得出结论，与谵妄和痴呆相关的认知障碍、情绪低落以及其他人格变量会导致住院时间延长，并在出院后更多地利用医院和其他卫生资源。文中还给出了对未来研究的建议。
