| Abstract: | ObjectiveTo assess the impact of training on use of inhalational techniques of different inhaler devices in spirometry proved cases of COPD and Bronchial Asthma in a tertiary care centre.MethodsA total of 128 spirometry proved cases of Asthma and COPD were enrolled. They were equally distributed in four groups comprising of 32 patients each according to their inhalation devices namely pMDI, Rotahaler, Accuhaler and Turbohaler. Patients were asked to demonstrate their inhalation technique and errors were noted according to their inhaler specific checklist. Patients were also interviewed regarding their knowledge about inhalation devices. Training about proper inhalation techniques was given to every participant. Rechecking of inhalation technique was again done at the second visit after 2 wks in the similar manner. Correct and incorrect steps of inhalation technique again evaluated by filling the checklist of the individual device to see post training improvement.ResultIn our study, out of total cases more than one third of the patients were >60 yrs of age (41.4%) and most of the patients were males (62.5%). During the interview at first visit, almost 92% patients claimed to know how to use the inhalation device correctly but in reality most of the patients (around 96.1%) had committed at least one mistakes in their inhalation technique among all the inhalation steps. Errors were noted in different steps of inhalation including the essential steps among all the four devices. Statistically significant improvement in inhalation techniques including the essential steps were found among all the four devices after educational intervention and demonstration of sequential steps involved in particular inhaler.ConclusionOur study confirmed a significant increase in the percentage of improvement in inhalation technique after proper demonstration and training about the inhalation devices. Inhalation technique including essential steps of inhalation significantly improved in all the four devices used. |
