Faktor-faktor yang Berhubungan dengan Ketepatan Penggunaan Inhaler pada Pasien Penyakit Paru Obstruktif Kronis di Rumah Sakit Prof. dr. Chairuddin P. Lubis Universitas Sumatera Utara

Abstract

Background. Chronic Obstructive Pulmonary Disease (COPD) is one of the leading causes of mortality in the world, and its prevalence keeps increasing every year, including in Indonesia. Inhalers are the main therapy for COPD, but many patients still use them with incorrect techniques, which can reduce treatment effectiveness and increase the risk of exacerbations. Objective. To identify respondent characteristics, accuracy of inhaler use based on device type, the most frequent errors, and analyze factors associated with the accuracy of inhaler technique among COPD patients. Methods. This study was an analytical observational study with a cross-sectional design, involving 88 samples of COPD patients who used inhalers at Prof. dr. Chairuddin P. Lubis Universitas Sumatera Utara Hospital, Universitas Sumatera Utara, Medan, 20155, INDONESIA. Results. Most respondents were male, aged ≥60 years, had a secondary education level, and were unemployed. The majority had been diagnosed with COPD for ≥2 years, belonged to group E, had GOLD stage 2 obstruction, and one comorbidity. There was a significant relationship between education level and inhaler use accuracy (p <0.0001), and between inhaler type and accuracy (p=0.043). The SMI device was used more correctly, while the pMDI device was most frequently used incorrectly. Patients with higher education levels were seven times more likely to use inhalers correctly than those with lower–middle education levels (OR = 7.284). Conclusion. Education level and inhaler type were significantly associated with the accuracy of inhaler technique among COPD patients. These findings highlight the importance of continuous education and evaluation of inhaler use to improve therapeutic effectiveness in COPD management.
