^aMDI: Metered Dose Inhaler ^bGood cooperation was defined as patient’s support of the administration activities with regard to the age-dependent abilities of the patient, i.e. for younger children no rejection of the administration process or correctly attending to the nurses’ instructions for older children and adolescents.
For each monitored inhalation process a reporting form with the assessment of each of the listed items was filed into the patient’s chart; positive feedback was forwarded if the administration processes were appropriate in the respective item and a negative feedback in cases if administration was inappropriate.
