Research looking at the use of technology to improve asthma adherence and outcomes has shown promise. Few studies have looked at the implementation of such research on larger asthma populations.


A Speech Recognition (SR) program was implemented for the total KPCO patient population of 480,142, of which 36,356 had asthma. To be included in this analysis, patients had to have a diagnosis of persistent asthma, filled 1 or more ICS prescriptions in the prior 6 months, and remain continuously enrolled with Kaiser Permanente for a two-year period (10/23/12-10/23/14). We compared adherence and exacerbation events one year prior to the intervention and one post intervention for 4,510 adults ages 19-64. Documentation of an exacerbation event was defined as a hospitalization, emergency room visit, or course of prednisone where asthma was the principal diagnosis.


Patient adherence, defined as portion of days covered (PDC), improved from 39.5% to 41.1% (P-value: 0.0001). There was no difference in asthma outcomes. The implementation of the SR program was found to have had a significant impact when evaluated using the dimensions of the RE-AIM framework. The initial cost of developing the SR system using internal resources was $11,000. Using an external vendor, it would have cost $24,000.


We showed that an SR reminder system was relatively easily adopted and implemented in our organization, at a low cost, that was easy to maintain and allowed us to reach a greater population in an effort to improve asthma medication adherence.
