Patients with uncontrolled asthma in the US and Japan have significantly worse physical and mental quality of life and require far more healthcare than patients with controlled asthma, according to the National Health and Wellness Survey.
The survey, conducted by Kantar Health, and involved patients aged 18 years or more, who were asked about their health status, behaviour, attitudes and outcomes.
The research found that patients with uncontrolled asthma, especially those in Japan, were more frequently hospitalised than patients with controlled asthma.
Patients in the US were also found to have visited hospital emergency departments a higher number of times.
Marco DiBonaventura, director of health economics and outcomes research at Kantar Health, said the research showed that nearly half of asthma patients in Japan and the US do not have their disease under control.
“Given the substantial prevalence of uncontrolled asthma in both the US and Japan, appropriate treatment and disease management should be reinforced in the healthcare community,” DiBonaventura added.
