Sputum colour may mark bacterial involvement in acute exacerbations of chronic obstructive pulmonary disease (COPD). However, whether colour vision deficiency (CVD) in COPD patients could impact the use of sputum colour charts as part of a guide to antibiotic use in exacerbations is unknown. This study used an exploratory mixed-method approach to establish the likelihood that COPD patients will be colour blind and whether this would result in the sputum colour chart being unusable in the context of the patients' self-management of their condition. CVD is under-reported in primary care and comorbidities in COPD patients increase the risk of acquiring CVD. Participants diagnosed with CVD and risk of acquiring CVD were able to use the sputum colour charts. Colour charts are likely to be usable even in the context of undiagnosed CVD in COPD patients.
痰的颜色可能标志着慢性阻塞性肺疾病（COPD）急性加重期的细菌感染。然而，COPD 患者的色觉缺陷（CVD）是否会影响痰色图表在加重期抗生素使用指南中的使用，目前尚不清楚。本研究采用探索性混合方法来确定 COPD 患者是否可能患有色盲，以及这是否会导致痰色图表在患者自我管理病情时无法使用。CVD 在初级保健中报告不足，COPD 患者的合并症增加了获得 CVD 的风险。患有 CVD 和有 CVD 风险的患者能够使用痰色图表。即使在 COPD 患者未诊断出 CVD 的情况下，色标图表也可能是可用的。
