Clinical care components for people with COPD are recommended in guidelines if high-level evidence exists. However, there are gaps in their implementation, and factors which act as barriers or facilitators to their uptake are not well described. The aim of this pilot study was to explore implementation of key high-evidence COPD guideline recommendations in patients admitted to hospital with a disease exacerbation, to inform the development of a larger observational study.
This study recruited consecutive COPD patients admitted to a tertiary hospital. Patient demographic, disease and admission characteristics were recorded. Information about implementation of target guideline recommendations (smoking cessation, pulmonary rehabilitation referral, influenza vaccination, medication use and long-term oxygen use if hypoxaemic) was gained from medical records and patient interviews. Interviews with hospital-based doctors examined their perspectives on recommendation implementation.
Fifteen patients (aged 76(9) years, FEV1%pred 58(15), mean(SD)) and nine doctors participated. Referral to pulmonary rehabilitation (5/15 patients) was underutilised by comparison with other high-evidence recommendations. Low awareness of pulmonary rehabilitation was a key barrier for patients and doctors. Other barriers for patients were access difficulties, low perceived health benefits, and co-morbidities. Doctors reported they tended to refer patients with severe disease and frequent hospital attendance, a finding supported by the quantitative data.
This study provides justification for a larger observational study to test the hypothesis that pulmonary rehabilitation referral is low in suitable COPD patients, and closer investigation of the reasons for this evidence-practice gap.
如果有高级别证据支持,慢性阻塞性肺疾病(COPD)患者的临床护理组成部分会在指南中被推荐。然而,这些措施在实施过程中存在差距,对其实施的阻碍因素或促进因素也未得到充分描述。这项试点研究的目的是探讨在因疾病加重而住院的患者中,关键的高证据COPD指南建议的实施情况,为开展更大规模的观察性研究提供依据。
本研究招募了一家三级医院连续收治的COPD患者。记录患者的人口统计学、疾病和入院特征。从病历和患者访谈中获取有关目标指南建议(戒烟、转诊至肺康复、流感疫苗接种、药物使用以及低氧血症患者的长期氧疗)实施情况的信息。对医院医生进行访谈,了解他们对建议实施的看法。
15名患者(年龄76(9)岁,预计第一秒用力呼气容积(FEV1)占预计值百分比58(15),均数(标准差))和9名医生参与了研究。与其他高证据建议相比,转诊至肺康复(5/15例患者)的利用率较低。患者和医生对肺康复的认知度低是一个关键障碍。患者的其他障碍包括就医困难、对健康益处的认知度低以及合并症。医生报告称,他们倾向于转诊病情严重且频繁住院的患者,这一发现得到了定量数据的支持。
本研究为开展更大规模的观察性研究提供了依据,以检验以下假设:在合适的COPD患者中,肺康复转诊率较低,并进一步调查这一证据与实践差距的原因。
