Inhaler technique education and asthma control among patients hospitalized for asthma in Jordan.
Objectives
To investigate the effect of inhaler technique education delivered by a clinical pharmacist to patients hospitalised for asthma, on inhaler technique scores and asthma control at three months post-discharge.


Methods
This pre-post interventional study in Jordan enrolled patients who had been admitted for asthma and were using controller medication by Accuhaler [Diskus] (ACC), Turbuhaler (TH) or Pressurized metered dose inhalers (pMDI). Inhaler technique was assessed using published checklists (score 0-9). Asthma symptom control was assessed by Asthma Control Test (ACT, range 5-25). Patients were assessed on admission (baseline), pre-discharge, and 3 months later. All patients received a 'Show-and-Tell' inhaler technique counseling service prior to discharge.


Results
Baseline data were available for 140 patients, 71% females, mean age 52.7 (SD 16.64) years, mean ACT score 10.0 (SD 4.8). Mean inhaler score was 7.5 (SD 1.52) with no significant difference between the inhaler groups (p = 0.174). After pre-discharge training, all patients had correct technique (score 9/9). After 3 months, mean inhaler scores were significantly higher than at baseline (8.14 (SD 0.87, p < 0.001), with mean change significantly higher for TH 1.21 (SD 2.25) and ACC 0.85 (SD 0.97) than pMDI (0.16; SD 0.72), p = 0.001. Symptom control improved significantly for all patients, with a mean increase in ACT score of 7.54 (SD 8.18), with no significant difference between the inhaler device groups (p = 0.326).


Conclusions
Patients hospitalized for asthma achieved correct inhaler technique after training by a pharmacist, and maintained better technique at 3 months than on admission. Significant improvements in ACT scores were documented for all inhaler groups.
