OBJECTIVES: The objective of this study is to evaluate the impact of two educational interventions that are demonstration versus pictorial Leaflet in patients using metered-dose inhaler (MDI). MATERIALS AND METHODS: This interventional study was done in patients who were prescribed drugs through MDI at Tuberculosis and Chest Department. The patients were enrolled in Group A or Group B as per random number table method. The method of use of MDI was assessed using a checklist based on the technique described in the WHO Guide to good prescribing. Patients in Group A were taught the use of MDI by demonstration of the technique by the investigator. Patients in Group B were educated about the technique by a pictorial leaflet based on the technique. Patients were followed up after 15 days and assessed for correct technique for use of the MDI. RESULTS: A total 100 patients were included in the study and were allotted to Group A (47) and Group B (53). Ninety-five percent of the patients had been taught by the treating physician about the method of use of MDI. All the patients at the baseline placed the lips tightly around the mouthpiece and held the aerosol as indicated in the manufacturer's instructions while the step least followed was coughing up the sputum before inhalation. The average steps correctly followed by the patients in Group A and B at baseline were 5.17 ± 2.07 and 5.11 ± 2.04, respectively. These improved significantly to 9.19 ± 0.67 and 6.67 ± 0.63 in Group A and B, respectively, postintervention. The five essential steps of using MDI were followed by 25.53% and 26.41% patients preintervention. An improvement in the technique of use of MDI was observed in 85.11% and 49.06% patients (P = 0.003) postintervention. All the ten steps of the technique were followed by 34.04% patients from Group A and none from Group B at postintervention evaluation (P = 0.0001). CONCLUSION: The inhalation technique for the use of MDI used by the patients is inappropriate. Educational interventions such as demonstration or pictorial leaflet help ensure a better use of the MDI.
