Abstract:
Background. Metered dose inhalers (MDIs) are not easy to use well. Every MDI user receives a manufacturer’s patient information leaflet (PIL). However, not everyone is able or willing to read written information. Multimedia offers an alternative method for teaching or reinforcing correct inhaler technique.
Objective. The aim of this study was to compare the effects of brief exposure to the same key information, given by PIL and multimedia touchscreen computer (MTS).
Methods. A single-blind randomized trial was conducted in 105 fluent English speakers (53% female; 93% White) aged 12–87 years in London general practices. All patients had had at least one repeat prescription for a bronchodilator MDI in the last 6 months. Inhaler technique was videotaped before and after viewing information from a PIL (n = 48) or MTS (n = 57). Key steps were rated blind using a checklist and videotape timings. The main outcome measures were a change in (i) global technique; (ii) co-ordination of inspiration and inhaler actuation; (iii) breathing-in time; and (iv) information acceptability.
Results. Initially, over a third of both groups had poor technique. After information, 44% (MTS) and 19% (PIL) were rated as improved. Co-ordination improved significantly after viewing information via MTS, but not after PIL. Breathing-in time increased significantly in both groups. Half the subjects said they had learned ‘something new’. The MTS group were more likely to mention co-ordination and breathing.
Conclusions. Short-term, multimedia is as least as effective as a good leaflet, and may have advantages for steps involving movement. MTS was acceptable to all age groups. The method could be used more widely in primary care.
