多学科非药物呼吸困难干预服务对中重度COPD患者的随机对照试验
本研究将113例中重度COPD伴致残性呼吸困难患者随机分为8周呼吸困难干预服务组（呼吸技巧、手持风扇、运动、节能、饮食建议）或等待名单对照组。干预组在CRQ掌握感、呼吸困难、疲劳、活动性呼吸困难强度和不愉快感方面均优于对照组。
要点
- 8周非药物呼吸困难干预可改善重度COPD患者的呼吸困难掌握感。
- 干预还改善呼吸困难相关的不愉快感和活动性呼吸困难强度。
- 干预对疲劳和呼吸困难维度也有益处，但焦虑抑郁未报告差异。
核心结论
- 8周呼吸困难干预服务改善了重度COPD患者的CRQ掌握感、呼吸困难、疲劳、活动性呼吸困难强度和不愉快感。
研究设计与样本
- 随机对照试验，113例中重度COPD患者按1：1随机分为8周干预组（n=54）或8周等待名单对照组（n=59）。
- 纳入标准为FEV1/FVC<0.70且FEV1≤60%预计值，mMRC呼吸困难评分≥2。
- 主要结局为CRQ呼吸困难掌握感子量表变化，采用改良意向性分析。
主要发现
- CRQ掌握感组间差异为0.5单位（95%CI 0.2至0.8；p=0.0262），干预组更优。
- CRQ呼吸困难组间差异为0.4单位（95%CI 0.1至0.7；p=0.005），CRQ疲劳组间差异为0.4单位（95%CI 0.1至0.7；p=0.014）。
- 活动性呼吸困难强度差异为-0.8单位（95%CI -1.4至-0.2；p=0.013），不愉快感差异为-1.2单位（95%CI -1.7至-0.6；p=0.001）。
- 参与者平均年龄70.9岁（±8.5），50%女性，平均FEV1=0.8 L（±0.3 L；34%预计值），mMRC评分3（IQR 3-4）。
临床怎么用
- 对中重度COPD伴致残性呼吸困难患者，可考虑提供8周多学科非药物呼吸困难干预服务。
- 干预内容包括呼吸技巧、手持风扇使用、运动、节能和饮食建议。

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is an often-progressive respiratory disease associated with disabling breathlessness. Breathlessness intervention services (BIS), which coach patients to self-manage breathlessness using non-pharmacological strategies, are effective in a variety of populations, including those with cancer and serious respiratory disease. This study aimed to compare the impact of the Westmead Breathlessness Service in people with moderate to severe COPD. METHODS: We analysed 113 participants randomised (1:1) with moderate/severe COPD (forced expiratory volume in 1 s (FEV1)/forced vital capacity <0.70 and FEV1 ≤60% predicted) and disabling breathlessness (modified Medical Research Council (mMRC) Breathlessness Score ≥2) to either an 8-week intervention involving breathing techniques, handheld fan use, exercise, energy conservation, dietetic advice (n=54) or 8-week wait-list control group (n=59). The primary outcome was change in Chronic Respiratory Questionnaire (CRQ) Mastery of breathlessness subscale. Secondary outcomes included change in other CRQ subscales (Fatigue, Emotion and Dyspnoea), exertional breathlessness intensity/unpleasantness (0-10 Numerical Rating Scale Score), anxiety and depression. Difference in change over 8 weeks between groups was compared using ANCOVA; p<0.05 statistically significant. FINDINGS: Participants were aged 70.9 (±8.5) years, 50% female, mean FEV1 =0.8 L (±0.3 L; 34% predicted), mMRC Breathlessness Score 3 (IQR 3-4). CRQ-Mastery improved following intervention compared with control (between-group difference 0.5 units; 95% CI 0.2 to 0.8; p=0.0262) using modified intention-to-treat analysis. Better CRQ-Dyspnoea and CRQ-Fatigue were seen in the intervention group (between-group difference-CRQ-Dyspnoea 0.4 units; CI 0.1 to 0.7; p=0.005, and CRQ-Fatigue 0.4 units; CI 0.1 to 0.7; p=0.014). Exertional breathlessness intensity (difference -0.8 units; CI -1.4 to -0.2; p=0.013) and breathlessness unpleasantness (difference -1.2 units; CI -1.7 to -0.6; p=0.001) also improved. INTERPRETATION: An 8-week BIS improved CRQ-Mastery, Dyspnoea and Fatigue, exertional breathlessness intensity and unpleasantness in people with severe COPD.
