201 An evaluation of actual versus perceived use of the I-neb by 10 adult CF patients to assess potential benefits of self monitoring online tool on adherence to nebulised therapy recommendations

The I-neb Adaptive aerosol device (AAD) is used widely by CF patients. The introduction of an online assessment tool facilitates patient self monitoring of nebuliser efficiency, treatment times and breathing techniques. Aim: To download and evaluate the use of the I-neb over a period of 1 year by 10 patients; comparing this information with the patients perceived use of the device to identify the potential benefit of a patient self monitoring tool on treatment concordance. Method: I-neb data from a 12 month period was downloaded from 10 patients who were issued with a short questionnaire asking them to outline how they had used their nebuliser. The results were returned to the CF Physiotherapist and feedback was compared with the downloaded data. Results: 70% of patients perceived their I-neb use to be higher than the data downloaded (11.56% and 70.88%) 3 patients underestimated their use ((0.48%-1.5%). Patients perceived that the I-neb provided a quick (80% estimated 75% dose delivery) method of drug delivery. The actual % dose which the patients received ranged from between 94–100% (average 98.4%) 80% perceived that they received >75% each treatment. With 20% perceiving their dose to be between 50 and 75%. 80% of patients expressed interest in the availability of a tool which provided feedback on frequency of I-neb use, time taken, % dose delivered and quality of the mesh of the device. Conclusion: Patient interest in an online method of self assessment tool indicates that this could be an effective method of improving concordance with treatment recommendations and reducing the gap between perceived and actual I-neb usage.
