The effectiveness of newly developed written asthma action plan in improvement of asthma outcome in children

Background: Providing asthma education about controller medication use and appropriate management of asthma exacerbation are the keys to improving the disease outcome. Many asthma guidelines recommend that physicians provide written asthma action plan (WAAP) to all of their asthmatic patients. however, the benefit of WAAP is unclear. Thus, we have created a new WAAP which is simplified in Thai and more user friendly. Objective: To determine the effectiveness of the newly developed asthma action plan in management of children with asthma. Methods: Asthmatic children who meet inclusion criteria all received the WAAP and they were followed up for 6 months with measurement of outcome variables, such as asthma exacerbation that required emergency room visit, unscheduled OPD visit, admission and school absence in order to compare with the past 6 months before receiving the WAAP. Results: The analyzed outcomes of forty-nine children show significantly reduced emergency room visit (P-value 0.005), unscheduled OPD visit (P-value 0.046), admission days (P-value 0.026) and school absence days (P-value 0.022). Well controlled group and mild severity group were not the factors that contribute to decreased emergency room visit but step up therapy may be the co-factor to decreased ER visit. Conclusions: The results of this study suggest that the provision of newly developed WAAP is useful for improving self- care of asthma patients and reducing asthma exacerbation.
