PURPOSE: Optimal inhalation technique is an important factor of asthma education plan. Appropriate inhalation technique improves drug delivery into the lungs thus helps better control of asthma. This study is undertaken in asthmatics to assess the impact of repeated inhalation technique education in every outpatient clinic visit on asthma control parameters and device maneuver skill.

METHODS: The study was enrolled between January 2014 and 2015 in our teaching hospital's outpatient asthma clinic in non-randomized prospective manner. Inhalation technique and asthma control parameters were assessed in every three month visits and patients are allowed to continue their medication during study period. All patients were analyzed for Asthma Control Test (ACT) score, PEF as % of predicted, asthma annual attack rate and also were monitored and labelled with 14 parameter checklist for device maneuvers.

RESULTS: Fifty eight patients (mean age 52,1±11 years; 43 women) with prior asthma diagnosis were included in the study. The study patients were divided in two groups; group-1: patients who had repeated education from the doctor (n:10; mean age 53±10;9 women) ; group-2: patients who had one or none education from health care provider (n:48; mean age 52±12; 34 women). Patients in two groups were matched according age, gender and educational status. Atopy was present in 39 of 58 (67%) patients and mean duration of asthma diagnosis was found as 14,7±9 years. Patients were on the same inhalation device for 88,1±17 months and average asthma attack rate was 0,36±0,9/year. There was no difference in PEF % (71,5±15% vs 74,4±22%,respectively), ACT (14,4±8 vs 17,6±5 respectively) and asthma attack rate (0,8±11 vs 0,27±0,8,respectively) between group-1 and 2. Device maneuver was found significantly better in group-1 patients. Eight of ten patients (80%) in group-1 were able to use their device with correct 12/14 maneuvers when compared 22 of 26 patients (46%) in group-2 (p=0,05).

CONCLUSIONS: This study demonstrated that repeated inhalation technique education may improve patient's device usage ability but, was not found as an unique factor to affect asthma control.

CLINICAL IMPLICATIONS: Inhalation technique must be monitored in every clinic visit and repeated education must be provided to asthmatic patients in every visit by health care provider in order to improve inhalation device skill.
