A Cochrane review evaluated interventions intended to improve inhaler technique in people with asthma. The evidence base included educational approaches delivered by health professionals and other structured methods designed to correct device-use errors. Across studies, training could improve inhaler technique compared with usual care, although the certainty of evidence and durability of benefit varied. The review also highlights an important practical limitation: improving technique is not the same as proving a reduction in exacerbations, hospitalizations or other hard outcomes, because many trials were small or short and used different measures of technique. For clinicians, the message is still highly actionable. Poor technique is a modifiable contributor to ineffective inhaled therapy, so technique should be checked directly rather than assumed from a prescription history. Teach-back, demonstration and repeat assessment are more reliable than asking whether the patient “knows how” to use the device. This aligns closely with NAPCON's emphasis on inhaler technique before step-up therapy. The publication supports embedding device review into routine asthma follow-up, particularly when symptoms remain uncontrolled despite apparently appropriate treatment.
