RESUMO
INTRODUCTION: The present study was designed to evaluate inhaler techniques and patient satisfaction with fixed-combination budesonide/formoterol dry-powder inhaler chronic obstructive pulmonary disease (COPD) in Turkey in real-life clinical practice. PATIENTS AND METHODS: A total of 442 patients with COPD [mean (SD) age: 63.2 (10.6) years, 76.5% were males] were included in this cross-sectional study conducted at 25 outpatient clinics across Turkey. Data on socio-demographic characteristics, characteristics of COPD, inhaler technique and satisfaction with dry-powder inhaler were recorded at a single crosssectional visit performed at the study enrolment. RESULTS: Patients were characterized by prominence of moderate to severe (78.1%) COPD, high rate of regular use of overall COPD medications (89.4%) and Turbuhaler® for an average of 33.7 months, predominance of males (76.5%), primary education (85.7%), urban location (68.3), ex-smokers (61.1%) and spending time outdoors for ≥ 4 hour/day (62.0%). Use of correct techniques was evident in majority of patients (≥ 94%), whereas inhalation maneuvers including breathing out gently away from mouthpiece without blowing into it (71.9%) and holding the breath for 5-10 seconds (78.3%) were performed correctly by lesser percent of patients especially in the older group (≥ 65 years, p< 0.05). Overall percent of patients with the feeling that she/he used the inhaler very/fairly correctly was 73.3%, while 86% of patients identified that they were very/fairly satisfied with the inhaler, irrespective of age and educational status. CONCLUSION: In conclusion, our findings revealed the majority of patients are able to use Turbuhaler® correctly regardless of the educational status, while older age was associated with higher rate of errors in inhalation maneuvers in the real clinical practice in Turkey. Majority of our patients identified Turbuhaler® to be very/fairly convenient regarding ease of use, portability, and usability with an overall self-confidence in using the inhaler correctly among 73% and the satisfaction rate of 86%; irrespective of age and educational level.
