Technique training does not improve the ability of most patients to use pressurised metered-dose inhalers (pMDIs).

Aims: According to guidelines, inhaler technique should be tested in all patients, particularly those with poorly controlled asthma. We aimed to assess uncontrolled asthma patients' ability to use a pressurised metered-dose inhaler (pMDI) using the Aerosol Inhalation Monitor (AIM, © Vitalograph).

Methods: Practices invited patients for a detailed clinical review by trained asthma nurses according to practice-agreed protocols.
