ABSTRACT
The high rates of mortality and hospitalization among elderly asthmatics, as well as their increasing healthcare costs have become an important public health issue. It would be worthwhile to assess whether inhaled corticosteroid (ICS) can resolve these problems. To explore ICS prescription rates for elderly asthmatics and the factors influencing them and to investigate their association with hospitalization and healthcare costs, we analyzed data from the National Health Insurance Claims Database for the same time frame (December 1 to February 28) across three different periods (2011-2012; 2014-2015; and 2017-2018), from which we identified 6,619, 5,619, and 6,880 elderly individuals, respectively. The prescription rates of ICS increased (52.8%, 65.5% and 68.8%, in the first, second and third survey period, respectively) and inversely the hospital admission rates declined (3.7%, 3.2% and 2.5%, in the first, second and third survey period, respectively). The total healthcare costs per month were significantly lower for patients who received ICS-containing regimens than for those who did not. A multivariate analysis revealed that increasing age, rural residence, receiving a prescription from a clinic, hospital admission, and prescription of asthma medications other than ICS were associated with non-prescription of ICS, whereas cross-boundary treatment increased the ICS-prescription rate. Our study suggests that increases in the prescription rate of ICS are associated with reduced hospital admission rates and lower medical costs in the real-world. ICS prescription rates in rural areas and at clinics, which remain low, need to be increased.
