A Systematic Review on KAP of Nebulization Therapy at Home.

Background: Inhalation is the preferred method of delivering medication for respiratory conditions such as asthma, chronic obstructive pulmonary disease, and other respiratory disease. A nebulizer converts a medication in liquid form to mist, so that the medication can be inhaled into the lungs. The aim of the study is to systematically review the knowledge, attitude, and practice of patients using nebulization therapy at home. The objective of the study is to review the procedure of nebulizer technique and to interpret the outcome of the studies. Method: Scopus, PubMed, BMJ, and other database from 2000 to 2020 were searched using Boolean operators. Title and abstract were screened for nebulizer technology and for inclusion and exclusion criteria. After full text screening 16 articles were included in the study. Result: Use of nebulizer at home was a challenge at all stages including setting up and operating nebulizer, filling up of medication, inhalation technique, end point dismantling, and maintenance. The main challenge experienced by the participants was with cleaning and disinfecting of nebulizer. There were studies that reported with 71.6% pathogen contamination due to inappropriate cleaning and disinfecting. Conclusion: Patients with respiratory disease using nebulizers at home find difficulty in appropriate and rational use of the device. Apart from the nebulizer user guidelines from the manufactures, it is suggested that a short audio visual demonstrating the appropriate and effective use of nebulizers and also its maintenance in their colloquial language with handout infographics would highly facilitate the effective use of nebulizers.
