Is simulation based training in inhaler technique of health care professionals more effective than written information?: A randomised controlled study

Background Evidence shows lack of competency among health care professionals (HCPs) to demonstrate correct inhaler technique to patients. Aim: We conducted a multicentre RCT at 2 tertiary hospitals to investigate whether simulation-based training using Aerosol Inhalation Monitor (AIM) and written information is more effective compared to training using written information alone. Method 160 HCPS (69 doctors, 80 nurses, 8 physiotherapists, 3 pharmacists) were randomised into 2 groups of simulation and written information (Intensive Intervention Arm (IIA; n=80)) and written information only (Minimal Intervention Arm (MIA; n=80)) arms. Inhaler technique was assessed using the AIM machine and checklist score (maximum score 20; 10 for MDI and 10 DPI) which were conducted immediate-post teaching and 1-week after. Results: Cumulative combined (MDI+DPI) median scores for the IIA group showed significant improvement at post-teaching compared to MIA at 1-week (p
