Tracey-Lea Laba et al surveyed to find high rates of cost-related underuse of asthma medicines among adults and parents of children with asthma, even in the context of national medicines subsidies. The extent to which people with asthma skipped doses when faced with cost pressures remained to be understood. The researchers conducted an online cross-sectional survey of adults and parents of children 5 to 17 years with asthma in Australia. The study involved n = 792 adults and n = 609 parents of children with asthma. Researchers developed logistic regression models for adults and children with asthma, controlling for key clinical and demographic factors. A cost-related underuse was reported by 52.9% adults and 34.3% parents, predominantly decreasing or skipping doses to make medicines last longer. The study found that young male adults were the most likely to under-use asthma treatments. Researchers suggest the need for targeted interventions to promote discussion of medicines and costs between doctor and patients.
