Knowledge and Practice of Inhalers and Spacers Among Nurses in Kalmunai North Base Hospital

Chronic respiratory diseases (CRDs) such as asthma and chronic obstructive pulmonary disease (COPD) pose a significant global health burden. Effective inhaler technique is paramount for optimal medication delivery in managing these conditions. However, improper use is prevalent and associated with poor disease control and increased healthcare costs. Nurses play an important role in educating patients on inhaler use. This study aimed to assess the knowledge of nurses about metered-dose inhaler (MDI) techniques at Base Hospital, Kalmunai North.A cross-sectional descriptive study was conducted in November 2024. A convenience sample of 65 nurses completed self-administered questionnaires assessing their knowledge of MDI steps and spacer usage, based on the National Asthma Education and Prevention Program (NAEPP) guidelines. Data were analysed using SPSS version 30. Adequate knowledge of inhalational technique was defined as correctly identifying at least three of the six essential MDI steps.The majority of nurses (84.6%) demonstrated adequate theoretical knowledge of inhaler techniques. However, 15.4% exhibited poor knowledge; 88% correctly identified shaking the inhaler, and 78% knew to remove the cap. Knowledge gaps were noted in steps like mouthpiece placement (65.2%) and triggering during slow, deep inhalation (65%). All nurses agreed on the benefit of spacers for children, but only 54.1% knew the correct cleaning method. Despite 80% reporting formal training, significant discrepancies in understanding specific steps and spacer usage were evident.While a significant proportion of nurses at Base Hospital, Kalmunai North, possessed adequate theoretical knowledge of inhaler techniques, a notable minority demonstrated poor knowledge. Specific areas requiring improvement include the precise execution of essential MDI steps and proper maintenance of the spacer. These findings underscore the need for targeted and ongoing educational interventions to bridge the gap between theoretical understanding and practical application, ultimately enhancing the effectiveness of inhaler therapy and improving patient outcomes in managing CRDs.
