New Results from the National Health and Wellness Survey Show More Than Half of Brazilian Asthma Patients Are Inadequately Controlled
NEW YORK, June 4, 2012—Having diagnosed asthma presents a significant quality of life burden in Brazilian patients, according to new findings from the National Health and Wellness Survey (NHWS), conducted by Kantar Health and presented today at the 17th Annual International Meeting for ISPOR (International Society for Pharmacoeconomic and Outcomes Research) in Washington, DC.
“It’s estimated that 300 million people worldwide suffer from asthma, and the prevalence is expected to increase as developing countries continue to adopt Western lifestyles,” says Jeffrey Vietri, Ph.D., Manager, Health Economics and Outcomes Research, with Kantar Health. “Brazil has been undergoing rapid economic growth, and like many emerging markets, the burden of adult asthma there is not well-understood.”
NHWS data for health-related quality of life (HRQoL) were analyzed, and Kantar Health found that HRQoL was significantly lower among adults with diagnosed asthma compared with those without an asthma diagnosis. The average mental component summary (MCS) score was 42.41 among asthma patients, versus 46.99 for those without asthma, and the physical component summary (PCS) score averaged 47.27 for asthma patients, versus 50.58 for those without asthma. The differences between asthma patients and those without asthma are clinically meaningful for both MCS and PCS. Results were similar when patient characteristics such as age, gender and comorbid disease burden were taken into account.
In addition, the NHWS showed that 52% of asthma patients had inadequate control of their symptoms. “Most asthma patients in Brazil have inadequate control of their asthma symptoms, and this is likely hurting them both mentally and physically,” Dr. Vietri says. “Matching these patients to appropriate treatments should go a long way toward improving symptoms and subsequently their quality of life.”
HRQoL was assessed using the SF-12 Health Survey Version 2 (SF-12v2), and asthma control was according to the Asthma Control Test (ACT). Visit Kantar Health’s website to download the full poster, “The Burden of Asthma in Brazil from the Patient’s Perspective.
About the National Health and Wellness Survey (NHWS)
The study’s results were drawn from the 2011 Brazil NHWS, a nationally representative, self-administered survey conducted annually via the Internet. Topics covered include the health status, attitudes, behaviors and outcomes among adults 18 or older.
Kantar Health conducts NHWS annually in the US, Europe, Asia and Latin America. The survey is the largest self-reported database in the healthcare industry.
