Community health worker case-detection of asthma or reactive airways disease in a resource-poor community in Nicaragua.

Prevalence of asthma in this community was high compared to previously reported national prevalence (15.2%), possibly due to increased exposure to risk factors. The questionnaire had a high area under the receiver operating characteristic curve, making it an excellent screening tool. This questionnaire could greatly increase the detection of asthma, allowing for education and referral for ongoing care.
