Inhaler device preferences in older adults with chronic lung disease

Abstract

Introduction: Patient preferences are important for medication adherence and patient satisfaction, but little is known about older adult preferences for inhaler devices. Methods: We developed a 25-item written self-administered questionnaire assessing experience with inhalers, prior inhaler education, and preferences with respect to inhaler device features and inhaler device teaching. We then conducted a cross-sectional survey of patients at least 65 years of age with chronic lung disease who had experience using inhaler devices for at least six months in the ambulatory setting. Results: Fifty participants completed the questionnaire. The majority of participants (80%) reported prior experience with a metered dose inhaler (MDI), but only 26% used an MDI with a spacer. Most patients (76%) had received formal instruction regarding proper use of the inhaler, but only 34% had ever been asked to demonstrate their inhaler technique. Physician recommendation for an inhaler, cost of the inhaler device, and inhaler features related to convenience were important with respect to patient preferences. With regard to inhaler education, participants prefer verbal instruction and/or hands-on demonstration at the time a new inhaler is prescribed in the setting of the prescribing provider’s office. Conclusion: Patient preferences for inhaler devices and inhaler education among older adults indicate physician recommendation, cost, and convenience are important. The impact of patient preferences on inhaler adherence and clinical outcomes remains unknown.
