BACKGROUND: Asthma guidelines recommend periodic assessment of impairment and risk factors to prevent exacerbations, which can lead to hospitalization and increased health care utilization and cost. According to recent meta-analysis data, fractional exhaled nitric oxide (FeNO) monitoring is associated with a 40-50% reduction in the risk of exacerbations.
OBJECTIVE: Cost modeling of these data indicates the potential for significant cost savings with FeNO use. Therefore, we attempted to verify this potential for cost savings within a real-world data base of Medicare beneficiaries.
METHODS: This retrospective observational study investigated asthma-related claims from a Medicare data base. Beneficiaries were included who had 2 years of records after an asthma-related inpatient hospitalization (IP) or emergency department (ED) claim. A case-crossover analysis was completed of asthma-related IP or ED events before and after FeNO use during the 2-year study period.
RESULTS: Of the 5911 asthma beneficiaries who met the inclusion criteria within the data base, 101 had an FeNO test during the 2-year study period. During the period before FeNO use, 98 of 101 (97%) beneficiaries had an asthma-related IP or ED event compared with 46 of 101 (46%) during the FeNO period. Asthma-related IP or ED claims and charges per beneficiary per day during the period before FeNO were 0.004 and $16.21 compared with 0.002 and $6.46 during the FeNO period (p = 0.0433 and p = 0.0133, respectively).
CONCLUSION: FeNO monitoring in beneficiaries with a history of exacerbations was associated with a substantial reduction in asthma-related IP and ED claims and charges. These data supported cost modeling estimates and demonstrated that FeNO use in asthma management was associated with significant cost savings.
