SPIROSMART: Novel smart-phone ambulatory spirometry

Focus: 

To conduct a clinical trial of a smartphone-based spirometry platform for chronic obstructive pulmonary disease (COPD)

Anticipated Impact: 

Earlier recognition and better management of reduced lung function, to improve outcomes and contain costs

Abstract: 

Spirometry is a well-established technique for monitoring lung function, including progression of obstructive lung diseases, by measurement of a forceful exhalation. Continued monitoring to recognize crises or medication deficiencies is impractical outside of clinical settings. SpiroSmart is an at-home/portable method using a smartphone's microphone and cloud server-based analysis to evaluate lung function and will be evaluated in a clinical trial. Multiple technical challenges of using a consumer smartphone have been overcome, and the fundamental premise has been validated. Three different patient cohorts will be tested, comparing the proposed platform to approved portable spirometry devices in clinical settings. The data will be used to refine the analysis algorithm and display of results to patients and providers, and will form an FDA 510(k) clearance package. Cost savings should result from less expensive monitoring and earlier recognition of impending crises.

We have completed our VA and Bangladesh study and have 60 users from the VA and nearly 4000 from Bangladesh. We are in the midst of data analysis and producing our next round of performance numbers. We have also received some great press on our work, which has led to conversations with new partners.
