To determine the prevalence of cognitive impairment in chronic obstructive pulmonary disease (COPD) patients using the Rapid Cognitive Screen (RCS).
Cross sectional study.
A total of 106 men and women with COPD 50 years of age or older.
Pulmonary ambulatory clinic in a tertiary academic center in St. Louis, Missouri, USA.
We enrolled patients with COPD who completed the RCS tool. Patients were classified as having normal cognition, mild cognitive impairment (MCI), or dementia if they scored ≥ 8, 6-7, or ≤ 5, respectively. The prevalence of each category was measured, and patients' baseline characteristics were compared.
One hundred and six patients completed the RCS. Of those, 36 (33.9%) patients scored ≤ 5 on the RCS, 33 (31.1%) scored 6 or 7, and 37 (34.9%) scored ≥ 8. The prevalence of dementia, MCI, and normal cognition were 33.9%, 31.1%, and 34.9%, respectively. Baseline lung function was not different between patients with normal cognition and those with abnormal cognition (FEV1 1.53 ± 0.39 vs 1.45 ± 0.32 L). In patients with abnormal cognition, there was no difference in patients' characteristics between patients with MCI or dementia.
Cognitive impairment is highly prevalent in patients with COPD. RCS successfully identified cognitive impairment in COPD. We recommend performing RCS in patients with COPD routinely.
使用快速认知筛查（RCS）确定慢性阻塞性肺疾病（COPD）患者认知障碍的患病率。
横断面研究。
共 106 名年龄在 50 岁或以上的 COPD 男性和女性患者。
美国密苏里州圣路易斯市三级学术中心的肺门诊。
我们招募了完成 RCS 工具的 COPD 患者。如果患者的得分分别为≥8、6-7 或≤5，则将其归类为认知正常、轻度认知障碍（MCI）或痴呆。测量了每个类别的患病率，并比较了患者的基线特征。
106 名患者完成了 RCS。其中，36 名（33.9%）患者的 RCS 得分≤5，33 名（31.1%）得分 6 或 7，37 名（34.9%）得分≥8。痴呆、MCI 和认知正常的患病率分别为 33.9%、31.1%和 34.9%。认知正常的患者与认知异常的患者之间的基础肺功能没有差异（FEV1 1.53±0.39 与 1.45±0.32 L）。在认知异常的患者中，MCI 或痴呆患者的特征没有差异。
COPD 患者认知障碍的患病率很高。RCS 成功地识别了 COPD 中的认知障碍。我们建议常规对 COPD 患者进行 RCS 检查。
