The association between asthma control and health care utilization, work productivity loss and health-related quality of life

J Occup Environ Med. 2009 Jul;51(7):780-5. doi: 10.1097/JOM.0b013e3181abb019.


Objective: To determine the association between asthma control and health outcomes.

Methods: Cross-sectional data on asthmatic patients were from the 2006 U.S. National Health and Wellness Survey. Asthma control was determined by the Asthma Control Test. Outcomes assessed included work productivity loss/activity impairment, health-related quality of life, and resource utilization. Effects of asthma control on outcomes were determined with linear and Poisson regression models.

Results: There were 2767 uncontrolled asthmatics and 2912 controlled asthmatics. Adjusting for confounders, controlled asthmatics reported (P < 0.001) higher physical and mental health-related quality of life scores (SF-8); fewer emergency room visits, hospitalization days, and medical provider visits; lower levels of overall work productivity loss and activity impairment.

Conclusion: Results indicate that asthma control is associated with better health outcomes. Management with therapies optimizing asthma control may reduce direct and indirect costs of treatment.
