在开吸入器处方时，重要的是要考虑到患者的可用性、偏好、信心和满意度。本研究使用新型干粉吸入器(DPI)Revolizer®评估了阻塞性呼吸道疾病患者和未使用吸入器的健康受试者的这些参数。在这项有100名参与者[50名健康参与者、45名轻度哮喘患者和5名轻度慢性阻塞性肺疾病(COPD)患者]的开放式前瞻性多中心研究中，所有参与者都接受了有关使用Revolizer的指导和培训，然后参与者在两次访问中演示了吸入技术。记录执行三次正确的连续尝试所需的平均时间和错误(包括严重错误)的数量。参与者在每次访问时通过问卷的方式被问及易用性、偏好、信心和满意度。被试在访视1完成三次连续正确尝试所需的平均时间为3.75±2.10分钟，而访视2的平均时间为3.07±1.32分钟(P<；0.01)。错误次数从第一次访问减少到第二次访问。超过85%的参与者认为Revolizer易于使用，超过75%的参与者更喜欢它。在两次访问中，Revolizer对所有参与者的信心和满意度得分很高。Revolizer是一种易于使用的设备，是轻度哮喘和COPD患者以及以前没有使用吸入器经验的健康参与者的首选设备。参与者对使用革命者感到自信和满意。
While prescribing an inhaler device, it is important to take into account the usability, preference, confidence, and satisfaction of the patients. The present study assessed these parameters with Revolizer®, a novel dry powder inhaler (DPI), in patients with obstructive airway diseases and in device-naïve healthy participants. In this open-label, prospective, multicentre study with 100 participants [n = 50 healthy participants, n = 45 mild asthma patients, and n = 5 mild chronic obstructive pulmonary disease (COPD) patients], all participants were instructed and trained on the use of Revolizer and then the participants subsequently demonstrated the inhalation technique at two visits. The average time required to execute three correct consecutive attempts and the number of errors (including critical errors) were recorded. Participants were asked about the ease of use, preference, confidence, and satisfaction by means of a questionnaire at each visit. The average time required by the participants to achieve three correct consecutive attempts at visit 1 was 3.75 ± 2.10 min, which significantly reduced at visit 2 (3.07 ± 1.32 min, P < 0.01). The number of errors decreased from visit 1 to visit 2. More than 85% participants found the Revolizer easy to use, and it was preferred by more than 75% participants. Revolizer scored high on the confidence and satisfaction of all participants at both visits. Revolizer is an easy-to-use and a preferred device in patients with mild asthma and COPD, as well as in healthy participants with no previous experience of using inhalation devices. The participants felt confident and satisfied using the Revolizer.
