Purpose This study aimed to evaluate handling of six common inhalers and determine correlations between correct inhaler technique patient demographics/ clinical variables. Methods A total 180 chronic obstructive pulmonary disease (COPD) patients were crossed-over handle their past-experienced among (pMDI, Aerolizer, Handihaler, Breezhaler, Turbohaler, Diskus) randomly, without receiving verbal or demonstrative instruction (baseline assessment). Inhaler was assessed using previously defined checklists. The use the then demonstrated evaluated for again. Demonstration repeated until a achieved. Number counselling attempts needed complete right handling, demographics variables recorded. Results mean percentage steps showed that pMDI is significantly lower than all other (76.01 ± 12.61 vs 84.18 10.87, 84.60 12.10, 85.91 9.82, 90.63 9.29 91 10.22 Diskus, Handihaler respectively, at P < .001). Breezhaler lowest participants with least 1 critical error (20%) however, highest (85.19%) .05. achieved after 1st attempt, only included in 3rd 4th (5.93% 0.74%, respectively). Weak very weak found demographics/clinical Conclusions not preferable by COPD patients. DPIs vary ease use, so therapy must be individualised on basis assessment counselling.
