Introduction

Accurate diagnosis and treatment is essential to optimise the health of people with asthma however, accessing spirometry and evidencing variation in airflow can be challenging. Home assessment could be a viable solution to enable faster clinical decisions.

Aims 

This study tested the hypothesis that the NuvoAir 12 week Asthma Program (supported virtually by physiologists) would enable accurate diagnosis and optimal treatment and be a positive experience for those assessed.

Method

A retrospective review of data collected from the first 40 patients who completed the NuvoAir Asthma Program by 31st January 2023. Data included: demographics, spirometry quality and engagement, outcomes and experience.

Results

The data from 40 people (32 female), mean (±SD) age 44.5 (±15) years were analysed, 50% were referred with an uncertain diagnosis of asthma and 50% for assessment of uncontrolled symptoms. Over the 12 weeks, 97% completed spirometry at least once weekly (range 1-4) with 77% of spirometry tests achieving acceptable grade A-C spirometry (graded using ATS/ERS 2005 guidelines). 12 weeks of home assessment enabled 67% to receive an accurate diagnosis, 40% to have their therapy optimised and 22% to be referred for an alternative diagnosis. 28/40 (70%) responded to an experience survey; 86% reported the NuvoAir Program helped them detect changes in their lungs and improved their understanding of their health. Collectively, participants gave the Program an NPS (net promoter score) of 68.

Conclusion

A home assessment program with high engagement and data quality successfully enabled diagnostic confirmation and treatment optimisation in people with uncertain/uncontrolled asthma.
