To investigate whether the inhalation technique improved among patients with asthma and chronic obstructive pulmonary disease after an Inhalation Technique Assessment Service (ITAS), and to assess the patients' and pharmacists' perceptions of ITAS.
This uncontrolled, pre-post study included 405 patients recruited from 42 Norwegian pharmacies. Inhalation technique was assessed by trained pharmacists before ITAS (baseline), directly after (follow-up 1) and three months after ITAS (follow-up 2), and analyzed statistically using SPSS. Perceptions of ITAS were assessed using a questionnaire.
488 ITAS were performed. At baseline, 8% of the inhalation technique demonstrations were rated as optimal and 31% as acceptable. Following ITAS, this increased to 72% (optimal) and 86% (acceptable). At follow-up 2 inhalation technique remained significantly higher than baseline (optimal: 52%, acceptable: 75%). The median rate of wrong steps decreased from 25% (baseline) to 0% (follow-ups). The usefulness of ITAS was rated 4 on a 5-point Likert scale.
Inhalation technique improved significantly after ITAS for both new and experienced users and all assessed devices. The technique remained significantly improved at follow-up 2. ITAS was well accepted by pharmacists and patients.
ITAS can contribute to significant improvements in inhalation technique among patients using inhaler devices.
探讨吸入技术评估服务（ITAS）是否能改善哮喘和慢性阻塞性肺疾病患者的吸入技术，并评估患者和药剂师对 ITAS 的看法。
本研究为非对照、前后对照研究，共纳入了 405 名来自挪威 42 家药店的患者。经过培训的药剂师在 ITAS 之前（基线）、直接之后（随访 1）和 ITAS 后三个月（随访 2）对吸入技术进行评估，并使用 SPSS 进行统计学分析。采用问卷调查评估对 ITAS 的看法。
共进行了 488 次 ITAS。基线时，8%的吸入技术演示被评为最佳，31%被评为可接受。ITAS 后，这一比例分别增加到 72%（最佳）和 86%（可接受）。随访 2 时，吸入技术仍明显高于基线（最佳：52%，可接受：75%）。错误步骤的中位数比例从基线时的 25%降至 0%（随访）。ITAS 的有用性在 5 分制的 Likert 量表中被评为 4 分。
对于新患者和有经验的患者以及所有评估的设备，ITAS 可显著改善吸入技术。随访 2 时，技术仍显著改善。ITAS 得到了药剂师和患者的认可。
ITAS 可以显著改善使用吸入器设备的患者的吸入技术。
