Objective  we want to construct a rating scale for the key technique using the inhaler device for patients with chronic airway disorder and to provide a reference tool for the scientific evaluation of patients’ techniques in the use of inhaler devices. Methods Through literature review and Delphi expert consultation, the items of the rating scale were determined, and the weights and assignments of the items were determined through the analytic hierarchy process. The resulting evaluation form was used for clinical assessment of patients, and the differentiation of each item was tested by the critical ratio method.Results After the two rounds of consultation, the positive coefficients of experts were 95.24% and 100%, the expert authority coefficients were 0.988 and 0.990, and the Kendall-W coefficients were 0.371 (P<0.001) and 0.654 (P<0.001), respectively. The final form, consisting of 10 operational items for evaluating key inhaler techniques for patients with chronic airway disorder, was finalized. The results of the hierarchical analysis showed that the consistency ratio CR was 0.088<0.10, which satisfied the consistency test. The top 5 key operational steps were medication preparation, exhalation, holding the mouthpiece, inhalation, and breathholding. Used for clinical patient assessment showed better discrimination of items (t ≥ 3, P<0.05).Conclusion The rating scale for the technique using the inhaler device for chronic airway disorder constructed in this study is scientifically reliable, convenient, and practical, which can be used as an objective evaluation tool to assess patients’ skill in inhaler device use.
