Evaluate the feasibility of the COPD Web and its study design and study procedures and to increase the understanding of the potential effect of the tool in order to provide guidance for a future large scale trial.
Parallel-group controlled pragmatic pilot trial.
There was a total of 83 patients with COPD (mean age 70 ± 8 years with a forced expiratory volume in first second percent predicted of 60 ± 17%). The intervention group (n = 43) was introduced to and had access to the COPD Web in addition to usual care, while the control group (n = 40) received usual care alone.
The feasibility of the COPD Web (i.e., if and how the COPD Web was used) was automatically collected through the website, while outcomes on health, conceptual knowledge, and physical activity (PA) were collected through questionnaires at baseline, 3 months and 12 months.
At 3 months, 77% of the intervention group was considered users, and the majority of time spent on the site was related to PA and exercises and was spent during the first month (>80%). In addition, the intervention group reported increased PA (odds ratio [OR] = 4.4, P < .001), increased conceptual knowledge in five domains (OR = 2.6-4.2, all P < .05), and altered disease management strategies (e.g., increased PA) (OR ≥ 2.7 P < .05) in comparison to the control group. The latter was also different between groups at 12 months (OR = 3.7, P = .044). Knowledge of PA was correlated with level of PA (ρ = .425-.512, P < .05) as well as to the use of PA as a strategy to manage their disease (χ = 11.2-32.9, P < .05).
Giving patients with COPD access to the COPD Web in addition to their ordinary primary care might be an effective shorter term (3 month) strategy to promote self-management. However, these results needs to be confirmed in a definitive large-scale trial. Key points Even though self-management strategies are an important part of chronic obstructive pulmonary disease (COPD) management, access to support for such strategies are limited for a large part of the COPD-population. Promoting self-management through the COPD Web might increase short-term levels of physical activity, promote conceptual knowledge and alter disease management strategies. The primary care COPD population in this study experienced limited impact of the disease in daily life, limited exertional dyspnea, and high generic quality-of-life, but vastly reduced levels of physical activity. A future large scale study should include strategies to encourage greater exposures to the COPD Web, including an extended analysis of factors associated with using or not using the tool over time and its impact on outcome measures, objective measures of conceptual knowledge, and physical activity, and it should include a large enough sample size to enable sub-group analyses and strategies to enhance recruitment.
评估慢性阻塞性肺疾病(COPD)网络平台的可行性及其研究设计与研究程序,并增进对该工具潜在效果的理解,以便为未来的大规模试验提供指导。
平行组对照实用型试点试验。
共有83例COPD患者(平均年龄70±8岁,第1秒用力呼气容积占预计值百分比为60±17%)。干预组(n = 43)除接受常规护理外,还被介绍并可使用COPD网络平台,而对照组(n = 40)仅接受常规护理。
通过网站自动收集COPD网络平台的可行性(即是否使用以及如何使用COPD网络平台),同时在基线、3个月和12个月时通过问卷调查收集健康、概念性知识和身体活动(PA)方面的结果。
在3个月时,干预组中77%的患者被视为使用者,在该平台上花费的大部分时间与PA和锻炼相关,且主要集中在第一个月(>80%)。此外,与对照组相比,干预组报告PA增加(优势比[OR]=4.4,P<.001),五个领域的概念性知识增加(OR = 2.6 - 4.2,均P<.05),疾病管理策略改变(如增加PA)(OR≥2.7,P<.05)。在12个月时两组之间也存在差异(OR = 3.7,P = .044)。PA知识与PA水平相关(ρ = .425 - .512,P<.05),也与将PA作为疾病管理策略的使用相关(χ = 11.2 - 32.9,P<.05)。
除常规初级护理外,让COPD患者使用COPD网络平台可能是促进自我管理的一种有效的短期(3个月)策略。然而,这些结果需要在确定性的大规模试验中得到证实。要点 尽管自我管理策略是慢性阻塞性肺疾病(COPD)管理的重要组成部分,但对于很大一部分COPD患者群体而言,获得此类策略支持的途径有限。通过COPD网络平台促进自我管理可能会提高短期身体活动水平,促进概念性知识,并改变疾病管理策略。本研究中的初级护理COPD患者群体在日常生活中受疾病影响有限,运动性呼吸困难有限,总体生活质量较高,但身体活动水平大幅降低。未来的大规模研究应包括鼓励更多接触COPD网络平台的策略,包括对随着时间推移使用或不使用该工具的相关因素及其对结果指标、概念性知识的客观测量和身体活动的影响进行扩展分析,并且应包括足够大的样本量以进行亚组分析以及增强招募的策略。
