Abstract

Objective

Few patients with asthma have disease that is well-controlled, particularly in Latin American countries. The purpose of this study was to investigate whether partly controlled and uncontrolled asthma are associated with increased costs for asthma-related medications and health care utilization compared with well-controlled asthma in five Latin American countries.

Methods

Using the Global Initiative for Asthma guidelines, we classified respondents from the Latin American Asthma Insights and Management survey into those with well-controlled, partly controlled, and uncontrolled asthma and compared the utilization of health care services and costs among these groups.

Results

Most respondents to our survey (93%) had asthma that was classified as partly controlled or uncontrolled. Across all countries, patients whose asthma was partly controlled or uncontrolled had greater use of asthma-related medications and medical services than did patients whose asthma was well-controlled. After adjusting for age, sex, and country of residence, total costs for asthma-related medications and health care were greater in patients whose asthma was classified as partly controlled and uncontrolled.

Conclusions

Our findings indicate that patients with asthma that are not well-controlled used more health care resources and had greater medical costs in Latin America.
