Past studies have found that medical patients with the diagnosis of depression (comorbidity) have longer hospital lengths of stay (LOS) than those without the diagnosis of depression. This suggested that scores on a depression scale would be positively correlated with LOS. On a rehabilitation ward, 14 stroke and 17 amputee patients were given the Geriatric Depression Scale (GDS) and lengths of stay were recorded. Correlations between GDS scores and LOS were +0.575 for stroke and +0.266 for amputee patients, both in the hypothesized direction. Explanations considered included: (1) depression and medical illness each produce morbidity which summate to require increased LOS; (2) depression delays medical recovery as well as the appearance of medical recovery, and (3) discharge planning is complicated by depression. When depression is associated with inpatient medical illness, DRGs may need to be reevaluated.
过去的研究发现，被诊断患有抑郁症（合并症）的内科患者住院时间比未被诊断患有抑郁症的患者更长。这表明抑郁量表得分与住院时间呈正相关。在一个康复病房，对14名中风患者和17名截肢患者进行了老年抑郁量表（GDS）测试，并记录了他们的住院时间。中风患者的GDS得分与住院时间的相关性为+0.575，截肢患者为+0.266，两者均符合假设方向。考虑的解释包括：（1）抑郁症和内科疾病各自产生的发病率相加，导致住院时间增加；（2）抑郁症会延迟医疗康复以及康复的显现，（3）抑郁症使出院计划变得复杂。当抑郁症与住院内科疾病相关时，可能需要重新评估诊断相关分组（DRGs）。
