Jane Scullion provides some simple and practical advice on optimal inhaler device selection for adults and children, in the first of two feature articles.

Getting the device right for the patient is an important clinical need, but we also need to be aware of patient factors. If people are not engaged with us, then they are less likely to use their inhaler.7

There are additions to devices, such as dose counters, and more intuitive devices with fewer operational factors, but we need to ensure that these features contribute to making the person comfortable in using their inhaler, rather than be dazzled by yet another new device.

The use of nebulisers is not routinely recommended unless there is a clinical need. This type of device can give out high doses of medication and can cause problems, such as hypokalemia, and can lead patients to rely on them rather than seeking appropriate medical help.3, 8

Conclusions

The optimal device for both children and adults is dependent on many factors. Given that there is little difference in terms of clinical effectiveness, in the end it generally comes down to what medication is required within its product licence, the required inspiratory flow rate, and whether a person can and will use it.
