The metered dose inhaler (MDI) technique of 30 elderly patients (mean age 79.9 years) was assessed. Sixty per cent were competent, though only 10% had an ideal technique; 40% were incompetent. Inadequate timing of actuation and inhalation was the most frequent error made. Competence was significantly related to mental status questionnaire (MSQ) scores of 7/10 or more. Patients who were first prescribed an MDI in hospital were significantly more likely to be competent than those prescribed an MDI by the general practitioner. Competence was not related to age, underlying diagnosis or duration of MDI therapy. Elderly patients requiring MDI therapy should be carefully selected and properly instructed by the prescribing doctor.
对30名老年患者（平均年龄79.9岁）的定量吸入器（MDI）使用技术进行了评估。60%的患者操作合格，不过只有10%的患者技术理想；40%的患者操作不合格。触发和吸气时机不当是最常见的错误。操作合格与精神状态问卷（MSQ）得分7/10及以上显著相关。在医院首次开具MDI处方的患者比由全科医生开具MDI处方的患者操作合格的可能性显著更高。操作合格与年龄、基础诊断或MDI治疗时长无关。需要MDI治疗的老年患者应由开处方的医生仔细挑选并给予正确指导。
