DECISION TREE FOR THE SELECTION OF A PARTICULAR KIND OF DEVICE
PRACTICAL ASPECTS
Aspects important for selection of the appropriate device for an individual patient
When selecting an aerosol delivery device the following questions should be considered:
In which device is the desired drug available?
Which device will the patient be able to use correctly, given the patient’s age and clinical setting?
For which device and drug combination is reimbursement available?
Can all types of inhaled drugs prescribed for the patient be delivered by the same type of device?
Which device is most convenient for the patient regarding time of drug administration, device cleaning or portability?
How long can the device be used?
From controlled clinical trials no significant differences appear to exist between different kind of devices concerning their efficacy and tolerability. Therefore it can be assumed that an ideal patient thoroughly instructed in the correct use of his device can be treated successfully with any inhaler. However it has been demonstrated that only very few asthmatics meet the selection criteria of controlled trials. Therefore decision on a particular device cannot be made on the basis of a few predefined patient characteristics but should take into account the individual situation and preference of a certain patient.
