Influences of perceived medication necessity , medication concern, satisfaction with information received, and experience of exacerbation on adherence of inhaled combined bronchodilator and corticosteroid therapy in patients with chronic obstructive pulmonary disease
Abstract:
This correlational predictive study aimed to examine the influences of perceived medication necessity, medication concern, satisfaction with information received, and experience of exacerbation on adherence of inhaled combined bronchodilator and corticosteroid therapy in patients with chronic obstructive pulmonary disease (COPD). The sample consisted of 120 patients with COPD who came for follow-up visits at COPD clinic of Siriraj Hospital. Data were collected by questionnaires including: Demographic Questionnaire, Medication Adherence Report Scale, Beliefs about Medicines Questionnaire-Specific and Satisfaction of Treatment Explanation Questionnaire. Data were analyzed by using descriptive statistics and
logistic regression analysis. The results showed that the majority of participants (90%) of the sample were male, with average age of 73.16 years (S.D. = 10.14). More than half of the
sample (61.7%) had inhaled combined bronchodilator and corticosteroid therapy adherence, while perceived medication necessity, medication concern, satisfaction with information received and experience of exacerbation together contributed for 14.7% of variation on inhaled combined bronchodilator and corticosteroid therapy adherence in COPD (Nagelkerke R2
= 0.147). It was also found that medication concern and experience of exacerbation could predict inhaled therapy adherence in COPD (OR = 0.89, p < 0.05 and OR = 2.68, p < 0.05), respectively. Based on the studys results, it was suggested that nurses should pay attention to assessing medication concern and provide information about prevention and deal with side effect, emphasize the importance of medication adherence for the prevention of exacerbation
