Improvement of asthma control with a breath-actuated pressurised metred dose inhaler (BAI): a prescribing claims study of 5556 patients using a traditional pressurised metred dose inhaler (MDI) or a breath-actuated device

Abstract: A relationship has been reported between sub-optimal inhaler technique and control of asthma symptoms. Randomised controlled trials and systematic reviews may fail to accurately represent this relationship, by excluding patients who are unable to correctly use the reviewed devices. Breath actuated inhalers (BAIs) are reported to be easier to use than metered dose inhalers (MDIs). This study uses a large primary care medical record database (DIN-LINK) to examine the 'real-life' clinical effectiveness of a BAI v… Show more

“…For example, patients using the preferred Easibreathe device achieved greater asthma control than with an MDI, resulting in fewer GP consultations for their asthma. 34 In a key analysis of the DIN-LINK database of UK general practices, which compared outcomes among 7412 patients using traditional and breathactuated MDIs to deliver ICS, breath-actuated MDIs appeared to improve outcomes; patients using breath-actuated MDIs were prescribed 25% less short-acting β 2-agonist, used up to 64% per cent less oral steroid, and up to 44% less antibiotics, than their counterparts using traditional MDIs. 34 If patients cannot use an MDI correctly after instruction and education they should be switched to a different device.…”

“…Furthermore, these discrepancies proved to correspond strictly to relevant differences in cost-of-usability for each inhaler [29][30][31]. This clear evidence supports the concept that "usability" (when stemming from patients' and nurses' controlled information) is a more complex issue than expected.…”

“…In other words, usability should be regarded as a much more multifaceted concept than those of "intuitivity", "preference", "acceptability", or "satisfaction", respectively, which should not be used as synonyms in the comparison of inhalers' performances. This suggestion is confirmed by the evidence that usability can also affect health care resources and the health technology assessment of different inhalers substantially [29][30][31].…”
