Stanford RH, et al. - Researchers undertook this cross-sectional survey study to determine the prevalence of as well as the factors related to intentional once daily (QD) use of twice-daily (BID)-indicated controllers among adult asthma patients. This study included 1,401 patients with asthma. Intentional QD use and BID use of their controller was reported by 30.9% and 69.1% of these patients, respectively. They noted that intentional QD use vs BID use was reported by healthier patients having better asthma control (lower asthma-associated ER and ambulatory visits and rescue medication use, and higher Asthma Control Test scores). In most cases, they recognized intentional QD use as a function of patients’ lack of perceived requirement for BID treatment (44.1%) or physician orders to use their controller QD (34.0%). The identified principal drivers of medication-taking behavior were perceptions about health and the need for controller use to control or treat asthma. The probability of reporting once daily use of inhaled controller was more in patients with less severe asthma but these patients still maintained asthma control.
