The purpose of this study was to assess the effect of psychiatric illness on length of stay and patterns of admission among AIDS patients hospitalized for medical illnesses. Medical records were abstracted for AIDS patients admitted to hospitals in Washington State from 1990 through 1992. Psychiatric comorbidity was defined by the presence of an International Classification of Disease-9 code reflecting psychiatric illness. Medical morbidity was addressed using CD4 count and AIDS-defining illnesses as markers of disease severity. Of 2834 admissions, 15% included one or more psychiatric diagnoses. Psychiatric illness (F 39.1; df 1,2830; p < 0.001) and discharge disposition (F 81.2; df 2,2830; p < 0.001) contributed significantly to the model, explaining increased length of stay (F 67.2; df 3,2830; p < 0.001). Future research needs to address the possible etiology of psychiatric comorbidity's contribution to length of stay and the effect on quality and cost of care.
本研究的目的是评估精神疾病对因内科疾病住院的艾滋病患者住院时间和入院模式的影响。对1990年至1992年期间华盛顿州医院收治的艾滋病患者的病历进行了摘要分析。精神疾病合并症通过反映精神疾病的国际疾病分类第9版编码来定义。使用CD4细胞计数和艾滋病界定疾病作为疾病严重程度的指标来探讨内科发病率。在2834例入院病例中，15%包括一种或多种精神疾病诊断。精神疾病（F 39.1；自由度1,2830；p<0.001）和出院处置（F 81.2；自由度2,2830；p<0.001）对模型有显著贡献，解释了住院时间的延长（F 67.2；自由度3,2830；p<0.001）。未来的研究需要探讨精神疾病合并症导致住院时间延长的可能病因以及对护理质量和成本的影响。
