Effectiveness of one-on-one coaching in improving pressurized metered dose inhaler (pMDI) technique among COPD patients: A prospective clinical study

Incorrect use of inhalers among asthma and COPD patients is very prevalent. Yet, no single intervention is considered standard of care. We aimed to conduct a COPD-specific investigation of active one-on-one coaching as the educational intervention to improve pressurized metered dose inhaler (pMDI) technique and COPD symptoms management.
