目的:了解慢阻肺患者在使用吸入装置中存在的问题,通过药师的用药指导,保证患者能完全正确使用吸入装置,同时为药师探索用药教育模式提供依据.方法:通过患者现场操作吸入装置,了解患者在使用过程中存在的问题,再由药师指导患者掌握正确的使用方法.结果:纳入的168例患者中联合用药47例,单一用药121例,总共使用吸入装置215例次,患者使用吸入装置过程中无错误所占比例最低3.72％ (8例次),41.40％ (89例次)存在3种错误,所占比例最高;对错误操作步骤进行统计,其中未呼气或呼气不充分、未屏气或屏气时间不足“,”Objective: To understand the problems existing in the use of inhalation device in patients with chronic obstructive pulmonary disease (COPD), to ensure that patients can use inhalation device correctly through the guidance of pharmacists, and to provide evidence for pharmacists to explore the mode of medication education. Methods: By operating the inhalation device on the spot, we can find out the problems existing in the use of the device, and then the pharmacist can guide the patient to master the correct use method. Results: Among the 168 patients included, 47 cases were used in combination, 121 cases were used singly, and 215 cases were used with inhalation devices. The lowest proportion of patients who used inhalation devices was3.72％ (8 cases), and 41.40％ (89 cases) had three kinds of errors, accounting for the highest proportion. The error operation steps are counted, among which the two most common operation errors are not exhaling or insufficient exhaling, not holding breath or insufficient holding breath time; 94.42％ (203 cases) need to be educated by pharmacists for 3 times to master correctly, and some patients need to be educated for 4 times or more. Conclusion: There are many operational errors in the use of inhalation devices, which need repeated medication guidance from pharmacists to master correctly.
